Chapter One

       The dim flicker of florescent lights filled the conference room with light. At it’s center two women and a man sat in silence. Shifting occasionally in their seats and looking nervous, they were patiently waiting. The minutes seemed like hours when suddenly the door swung open violently and in rushed an elderly looking man in a lab coat, two young females in business attire in tow.

       He quickly broke the silence with his slight German accent. “Please relax. I am Dr. Gruber and these are my assistants Svetlana and Bella.” He took a seat at the head of the table while his assistants sat in two chairs against the back wall. “First I would like to thank all of you for agreeing to help in our research. Because of your decision to volunteer we will make great strides toward helping millions of people in need.” He turned to Svetlana, a statuesque blonde. “The files please.” She rushed over and placed them on the table in front of him.

       “First we have Chris. 26 year old male. Six feet three inches, brown hair, green eyes, Caucasian…an aspiring artist. We love the arts, such an amazing talent to be able to capture beauty. Tell us Chris, why have you agreed to help us.”

       Chris shifted up in his seat glancing around the room. “Honestly Dr. Gruber I need the money. I want to open my own gallery and with the amount you are paying I couldn’t turn down the opportunity.”

       Dr. Gruber pursed his lips and stared intently at Chris. “Ambition is good, we like our subjects to have ambition. Of course the money is why you are all here. $500,000 is a lot of money. I’m sure you are all here for similar reasons. Anna?”

       Anna, a 27 year old beauty with porcelin skin and raven hair worn in a should length bob answered quickly. “My house is on the verge of foreclosure. I’d really like to help your project, but yeah… it’s the money that got me here.”

       “I see, and you Beth? “, said the Doctor. Beth, a 23 year old red head with tanned skin accented by freckles chimed in, “Cash is good, but your add intrigued me. Pushing the limits of body response, creating a new and better me, experiencing mood elevating highs like nothing I’ve ever known. I’m an adventurous woman doctor Gruber. I need to know this is all about.”

       “And you shall in good time my dear.”, said Gruber. “Bella, please hand out the consent forms.” Bella, a tall tanned brunette scurried around the room handing out forms and pens to the three. Dr. Gruber continued talking, “What you have in front of you is consent forms. By signing these you agree to take part in our experiments for as long as determined by us to achieve the desired results. You agree to participate in any way we wish, remain available at all times, and understand that changes – some even extreme – may occur to your mind and body. You will live at our facilities throughout the process and realize that privacy will not be an option. After signing the forms in front of you the money will be transferred into the accounts you dictated upon application to the program and only then will I explain more about what we are working on.”

       All three picked up their pens and looked down at the forms in front of them. Beth signed immediately and without hesitation. Chris looked over the form, which stated what the Doctor had just said but in more intricate legalize, then signed his name. Anna, sweat forming on her brow, looked sheepish and concerned. “Anna, are you having second thoughts?”, asked Doctor Gruber. Anna shook her head yes. “Now is the time to change your mind. If you are uncomfortable with participating you may leave and find another way to save your house.” Anna still seemed unsure. Gruber continued, “On your application you indicated the years you’ve spent turning that ramshackle brownstone into the home you always hoped to grow old in. Are you sure you want to throw that away?” Tears pooled in Anna’s eyes. She wiped them away, leaned down and signed her name.

       Bella quickly scooped up the forms from the three and left the room. “Right now she is depositing the funds into your accounts. You are now all participants in one of the greatest human experiments ever attempted!” Gruber stood and continued talking, “In signing those forms you agree to never divulge any part of these experiments to an outside party. Should you attempt to sue, press charges, or otherwise divulge our work you will be tried for breech of contract in the jurisdiction of our choosing, which is a small Eastern European nation with laws very tolerant of our projects.”

       

       Gruber stood, “Now with all those formalities out of the way I shall explain to you some of what is in store. Svetlana the lights and projector please.” Svetlana walked to the wall and with a couple of flicks of the switches the lights dimmed and the projector sprang to life with a power point presentation.

       “We are conducting amazing experiments in pushing the boundries of human response, growth, and sexual attunement. In other words, we are working on multiple fronts to perfect aspects of human sexuality. To do so we are running a great number of experiments in many different levels and manners, ones which will lead to cures for many issues and maladies and will unlock aspects of the human mind and body never before possible.” Generic slides of happy couples, hands holding hands, and romantic kisses flickered across the screen while Gruber continued, “The experiments are incredible strenuous and extensive and we promise that none of you will leave the same as when you entered, but should everything work as intended you will undoubtedly be impressed with the outcome.”

       Anna looked peaked, every time Gruber said the word sex she looked ready to run or throw up. Chris looked on curious though nervous, while Beth listened intently looking for more answers. Gruber continued his presentation, “You three were chosen out of hundreds of applicants for very specific reasons. Either you suffer from specific physical or mental hurdles we are looking to cure or posses the fortitude and background that lead us to believe you will see them all through.”

       Gruber’s eyes scanned them back and forth. “I trust that you find each other at least reasonably attractive as that will be key to your adaptability to the program.” Beth looked over at Chris and smiled a half smile, her mind running with thoughts of spending time with him. Chris smiled, cleared his throat and leaned up in his seat, while Anna stared down at the table barely breathing.

       “As you know the program for you began immediately for you upon signing the forms. Hence why we had you all tie up any loose affairs before coming today. I apologize that I’m unable to explain any more of what we will be doing just yet, but we do not want to bias any of the experiments. Now if you will all please rise and follow Svetlana and Bella the journey to a new you begins now.” Gruber motioned for them to rise and follow his assistants which all three did, Anna walking unsteadily behind the other two. Her mind racing with thoughts of dread of what might be in store.

       The assistants led all three out a door and onto an open tarmac. There waiting on a runway was a small private jet engines running and door open. Svetlana motioned toward the plane when Anna broke in, “Where are you taking us?!” Bella answered quickly in a lilting British accent, “My dear, you did not think these experiments would be taking place here did you? There are hundreds of laws against human experimentation alone. You will be traveling to a private facility on a foreign island. Now please board the plane.”

       Anna took two steps back, looking around for some sort of escape from what she had just gotten herself into. She didn’t want to lose her dreams, but the reality of what she had entered into filled her with dread. Sexual experimentation?! A strange island and no description of what they intended to do? What kind of people were Chris and Beth for going along so willingly? What was she going to endure? She started to turn and head back for the building muttering apologies and looking for the exit. Suddenly out of the door Dr. Gruber appeared. He grabbed her by the arm, “My dear I’m sure you’re not leaving after signing that form. Do you really want to be extradited to a nation that settles breach of contract with the death penalty.” Anna went ghost white. “That’s right”, continued Gruber, “it would be best for you to comply from here on out. You will not only be helping millions but you will also derive some incredible pleasure from the experience yourself.” He firmly pointed toward the plane. Anna paused, her head swimming with all the rapid information, force, and fear. She turned and timidly walked up the stairs and into the plane.

Chapter Two

       Once inside the plane Anna was escorted to a plush leather seat facing Chris and Beth. The doctor and his assistants boarded the plane and sat in the front in some deep discussion in a language none of the experimentees spoke. Anna looked sullen and terrified, she stared at the floor to avoid the gaze of Chris and Beth. Shortly after reaching cruising altitude Beth broke the silence between them. “I think this could be really amazing, there’s so much mystery and danger and from what the doc says it seems we’re in professional hands.” She leaned closer to Chris and touched his arm gently, “Besides, I can’t wait to get to know you both better.” Chris blushed, fully aware of her intentions, but it was Anna who spoke up next. “How can you be so cavalier about all of this. We’re on a plane going to god knows where! It’s Beth isn’t it?” Beth nodded at her. “Listen Beth in case you didn’t hear, they’re going to run experiments on us they haven’t described yet. They’re going to do things with us, and to us, involving our sex and sexuality? We might be landing to be fondled by a group of crazed Chimps for all you know.” This statement struck Chris and his expression quickly changed from flirty and bashful to worry. Anna continued, “My `sex’ experience to date consists of two long term boyfriends. Suffice it to say they always enjoyed it way more than I. I’m really terrified ok?! And I’m shocked you aren’t too.”

       Beth responded, “Two boyfriends and you’re what – 27? You’ve got to live more. I for one think it might be amazing and his promises of amazing new sensations and experiences…”, she mockingly shook, “send shivers through me.” Chris finally responded verbally, “Listen, it doesn’t much matter now does it? We’re already on the plane and the forms are signed. We might as well go along with the program.” Just as Anna was about to raise her voice and try to turn them to her side Bella walked up with a tray and three glasses. “Refreshments?” All three grabbed a glass and slurped them down. Vodka tonic? Anna thought. At least I can have that to calm my nerves. She leaned back and looked out the window contemplating her situation and how she might escape but became so sleepy as the minutes wore on. She looked down at her drink and over at Chris and Beth who were both slumped forward. There’s something in the drinks! She started to get up to confront Bella but was too tired. Before she knew it she was unconscious.

       The next thing she knew she was opening her eyes and trying to adjust to her surroundings. She still felt groggy, like the morning after sleeping off a bad night of drinking. Looking around the room she saw Chris and Beth both sitting on a bench facing her. It was some sort of a hallway with green tile on the walls floor to ceiling. Above her florescent light flickered and buzzed. She started to say something but heard the taping of shoes coming their direction from down the hallway. Doctor Gruber and two female nurses in scrubs were coming their way. Talking as he walked up to them Doctor Gruber said, “Welcome to the lab! We don’t want to waste any time so we’ll skip any additional introductions or formalities and begin the intake immediately.”

       Anna shouted at him, “Where the hell are we?! What did you put in our drinks?!” The doctor, almost expecting her reaction already had his hands raised in a stop motion. “You were all given a sedative to make the time pass more quickly on the flight and relax you. All you need to know is that you are now in the lab and under our control.” The hell we are though Anna, but as she went to raise and fight back her arms and legs refused to respond. “What’s wrong with me! Why can’t I move?!”

       Dr. Gruber sighed, “For both our protection and yours you were all slipped nanobots in your drinks. Amazing little devils, they have been replicating throughout your bodies for hours and have one primary function. They stop your muscle response when your brain signals violent tendencies. Further, they can be controlled from our remote viewing station where one of our staff can render you inert at any time.” Anna began to tear up at the hopelessness of their situation. “So we continue.”, said Gruber. “Please rise and follow me. He began walking down the hallway to a door at the end. Anna, Chris, and Beth all rose and followed him with the two nurses bringing up the rear.

The inside of the room was very formal and medical looking. Instruments, hoses, and wires of all sorts ran throughout the area and three gynecological table were set up facing one another with a stool in front of each. Anna, Beth and Chris stepped forward as the doctor beckoned them over to a table. “Please remove your clothing then turn around and face me. Chris and Beth began hastily stripping. Beth pulled her dress over her head in one motion then turned to face the doctor. “Everything please, underwear too.” She slipped two fingers inside the band of her thong and yanked them down over her legs. By this time Chris and Anna were also naked and standing in front of the doctor covering their genitals and breasts with their hands.

“Please drop your hands, it is quite ridiculous that you would show such modesty. Clearly you’re all going to be in intimate contact with one another. And yes Anna, we read your file and I assure you we’re going to leave the lights on here.”, said Gruber with a smile. They dropped their hands, Anna looking mortified and despondent at everyone seeing her naked. Chris looked scared and ashamed, but Beth seemed unfazed.

Gruber walked over to Beth first. “Good frame, thin but slightly curvy. Height 5’3”.” One of the nurses was diligently taking notes on a clipboard. Gruber cupped her breasts causing Beth to look away. “B cup, slight sag for her age.” He then squatted down and patted her thighs, “Spread your legs please.” Beth did as commanded as Gruber ran a hand up to her slit. “Medium hair growth, no trimming. And small retracted clitoris.” He stuck his index finger into a container of lubricant a nurse handed him then slipped his middle finger inside causing Beth to grunt. “Medium shallow with defined G-Spot. Vaginal orgasm potential.” He looked up at Beth, “I’m going to stimulate you now for a few moments. I want you to concentrate on the feelings of pleasure.” Beth closed her eyes and complied as Gruber began circling her clit with his thumb and rubbing against her G Spot. Within a minute Beth was leaning her slit into him and breathing heavily. Gruber continued his ministrations while talking, “Medium turgidity from the clitoris and quick heavy lubrication with light stimulation.” He pulled his hand away and moved over to Chris. Beth opened her eyes looking slightly disappointed.

Gruber squatted down in front of Chris. He began grabbing and inspecting his penis. “4 inches flaccid, medium size testicles three inches by two inches.” Chris seemed uncomfortable and worried as the doctor stood. “Chris, we need to get measurements of your arousal. We know by your application and intake forms you are straight so I will have one of my nurses step in for me. Eventually gender will be less important to you but for now we will do what makes you most comfortable as we need good accurate samples.”

Gruber stepped back and a plain looking brunette nurse with short hair knelt in front of him. She began to gently caress his penis with her fingers, running them up and down the shaft then circling the head. Chris gasped and she continued taking his cock firmly in her hand stroking it. Her other hand cupped his balls gently and she exhaled directly over his genitals. For all of her work though he was only becoming semi hard. Gruber looked over the papers on a clip board. “This is part of the reason you were selected Chris. You have physical and mental blocks that cause semi impotence. We are going to help you overcome that problem forever. Please fellate his member.” The nurse dutifully complied with a kiss to the tip of his penis, swirling licks underneath, and then taking the whole thing into her mouth. She pumped vigorously and Chris slowly hardened in her mouth groaning all the while. For a few minutes the only sound in the room was the slurp of the nurses mouth and Chris’ groans. Anna looked the other way and tried to pretend this wasn’t happening a foot away. Suddenly the nurse grasped the base of Chris’ cock firmly and pulled her mouth off while the other nurse quickly ran in with a caliper. “6 inches doctor by 2 inches in width. Testicles tight and full against his body.” “Good, now collect our specimen.” The kneeling nurse began rapidly licking the underside of his penis while the other nurse positioned a cup in front of his glans. Chris, began bucking and moaning, “Agggghh… Agghhh… I’m… I’m…”, with that he shot five spurts of cum into the collection cup. The nurse continued holding onto his cock and pulled him tightly against her body until the spasms of orgasm subsided. Gruber held up the cup and inspected it. “Very small sample, only 4cc’s and a velocity of ejaculation of only half a foot per second. These numbers will be a great baseline to judge our improvements off of.”

The nurse stood leaving a sweaty and spacy looking Chris staring down at his quickly shrinking cock. “Now on to you Anna.” She looked mortified and shut her eyes firmly as the doctor stepped in front of her. “34A cup breasts. Slender frame. 5’6” with 23 inch waist.” He knelt down in front of her and taped her thighs for her to spread. Reluctantly, Anna spaced her legs apart then felt his fingers probing her folds. “Very heavy pubic hair presence with medium labia majora hiding the minor completely when unaroused.” Again he slipped his finger into the lubricant and pushed inside of her. “Good depth, 4 inches unaroused, very small G-Spot. Medium clitoris, 1 inches from base half obscured by the hood.” He looked up at Anna who had stolen a glance down at him. “Now we proceed with arousal.” The doctor began pumping his finger inside her and circling her clit but Anna seemed unresponsive. “Subject not responding to digital manipulation, moving on to oral.” He leaned in and began licking her clit with long broad strokes then sucked it into his mouth and began rapid flicks of the exposed tip. All the while his fingers stroked inside her. Anna could not keep her composure under his incessant ministrations and began to pant. As he sped up and continued she let out a moan then began to tense. Dr. Gruber could tell an orgasm was building inside her and chose that moment to stop licking her clit. “Clitoris fully engorged is 2 inches with ½ inch exposed from hood. Very turgid. G-Spot still small but slightly swollen, lubrication adequate for penetration. Proceeding to test orgasmic response. Nurse.” The nurse stepped behind Anna and wrapped her arms around her cupping her breasts. Both supporting her and flicking her nipples the doctor went back to sucking on her clit and fingering her. Anna, though straight was so lost in the sensations she was unaware the female nurse was molesting her breasts. She began to moan, “Mmmmmmmm.” Her breathing rapid she began tense. Sensing the coming orgasm and wanting to get maximum result the doctor wrapped his free arm around her hips and pulled her clit into his mouth. He continued slurping quick and hard on her clit as Anna began vocalizing, “Arrhhhhhhh!!! Arhhhh!!!! ARRRRHHHHHH!!!” She came, and came hard. Only with her first boyfriend had she ever felt the waves of pleasure surging from her loins. They shot up through her body and combined with the aching pleasure from her nipples. Finally after a few moments she went slack and slumped back against the nurse who stood there steadying her.

“Good baseline orgasmic response. 7 strong contractions and 4 smaller ones with light pulse in clit. Nurse?” The nurse who had been working Anna’s nipples responded, “Hardened nipples, at ½ inch in length, sensitive and responsive to touch.” Gruber stepped to the note taking nurse and wiped his slick hand on a towel she held out. The other nurse steadied Anna on her feet, who was now red and clearly ashamed as Gruber spoke. “Sorry Beth, your turn will come soon as we are just beginning. I am pleased with the results so far and we have good baseline information to work off of. Now if each of you will please follow us to the chairs at the far end of the room we can complete or intake notations for the morning.”

Chapter Three

       Chris, Anna, and Beth followed Gruber and the nurses to the gynecological chairs at the other end of the room. The entire area looked very sterile and professional. Each chair had one large overhead light illuminating it with stirrups already extended. Beside each were various machines wires and a small table covered with a surgical towel. As they neared the chairs Gruber told them all to wait.

       “Now we continue our intake tests. Nurses?” One nurse took Beth’s hand and the other took Anna’s hand, leading them to the two furthest spaced chairs. Arranged in a circle, each chair faced toward the center giving the seated person a view of everyone else. Beth was helped up into her chair, wincing at the cool vinyl as it touched her skin. Anna was positioned in her chair the same, her legs like Beth’s, placed up into the stirrups. Only when the nurses began pulling straps out from underneath the chairs did they begin to panic. It was useless though, the nanobots prevented any attempts to fight the nurses or jump and run.

       As the nurse began pulling out the straps Anna screamed. Seeing her dismay Gruber walked over and placed a hand on her quivering knee, “I know you are feeling scared and helpless, that is normal given the circumstances. The straps are for your own safety. These tests can be very strenuous and we do not want you to involuntarily hurt yourselves or the staff.”

       The nurses continued strapping both women down. One across their forehead, both arms and wrists, both feet and thighs, and one across their hips; both women were now completely immobile. Hearts pounding in their chests and staring across the room at one another, Anna began to whimper. Beth meanwhile looked genuinely scared but more controlled, clearly awaiting her fate as it came. Finally, the nurses walked over to Chris, who looked terrified. With little other option he complied and was soon strapped to the third chair.

       “Now we begin the next test procedures. As you are different genders there will be different tests applied. I realize that relaxation will be a foregone conclusion for you all but I will try to ask you to concentrate on the physical sensations you are about to experience and understand that we have no desire to harm you.” With that Gruber sat on a stool in the center of the chairs and looked up at his nurses while pulling on rubber gloves. “Please begin applying the test to the ladies.”

       The nurses each raced to the two bound women and lifted the towels on the surgical carts next to them. Anna could only see out of the corner of her eye but there appeared to be several wires and pads along with jars of liquid. The wires were running off the table and behind her to some unknown location. Looking over at Beth her situation seemed the same, wires on a table running to what appeared to be a complicated bank of machines covered in dials and knobs.

       The nurses applied two yellow pads first, one above each woman’s heart and another on her abdomen above where her uterus would be. Then they went to the bank of machines and began clicking and turning knobs. Oddly enough to Anna, nothing seemed to happen. The nurse walked back over and brought two more pads with wires back. “The yellow ones are just for readings sweetie, it’s the white ones that are for the fun.”, said the nurse. First she rubbed a gooey stick substance over each breast and then pressed the pads firmly on her nipples. She returned to the table and then repeated the process with Anna’s clit. Beth received the same treatment, all be it with more composure than Anna was exhibiting.

       The nurses then returned to the machines behind the women’s chairs and hollered to Gruber, who was busy looking over a chart, that everything was ready. “Excellent, let’s get started then.”, he said with a smile. Anna was quivering with fear and could see even Beth was breathing rapidly and looking around the room in dreaded anticipation. At that moment both women heard the first clicks from behind them along with a low hum. A beat later they felt the first sensations from the pads. Both took a sharp intake of breath and tensed.

       Gruber spoke up, “Interesting sensations aren’t they Beth? Please describe them to Chris here.”

       Beth’s voice cracked as she started to speak, “It’s light, like hundreds of fingers brushing against my nipples…. down there…”

       “Excellent”, said Gruber “Please increase to full measure.”

       The nurses clicked more buttons and dials. Anna tensed fully and let out a moan, “Gwaaaaa”. Beth meanwhile was mewing and moaning on her own. More clicks and both women began flexing and tensing their hands and feet. Their muscles flexed and tensed against the straps. It was clear they were building toward a massive orgasm. The procedure continued to work them to a frenzy, with Beth plateauing first. Her breathing rapid, veins pulsing in her neck and brow furrowed she was straining against the straps to buck her hips and cum. Suddenly the hum behind her stopped and she went slack. “Arrrrr….”, she looked around the room like a frenzied animal. Meanwhile the same thing happened to Anna across the room. She whipped her eyes over a Gruber as the machines stopped, her lip pouting.

       “Don’t worry ladies, the machines will start again soon. Of course you won’t get to cum right now. You see the yellow lead wires are feeding the computer with information on your sexual response. Every time it reaches the point of orgasm they shut down the stimulus. You see we need to know how far we can push your limits, what your maximum arousal looks like, and prepare you for your entrance to the program.”

       As Gruber finished talking Beth prepared to plead for mercy, but she never got the chance. Instead the machines kicked back on and both women began straining against their straps. Beth glanced over at Anna, she was so hot straining to cum. And wet, her juices were running down her ass cheeks and pooling on the table.

       Both women continued to writhe against their straps as Gruber sat on a stool and wheeled over to Chris. Both nurses walked over to either side of the chair as though they’d done all of this a hundred times before. Gruber adjusted his gloves then took Chris’ penis in his hand. It was already hard from watching Anna and Beth, allowing Gruber to give it a closer inspection. He cleared his throat and the nurse to Chris’ right stepped up close to his head. She pulled her chest against his head and leaned down so he could only look directly in her face.

       “Sweetie”, she spoke up, “I want you to concentrate on me, ok?” She leaned in and kissed him sweetly on the lips then pulled back and stroked his head gently while staring in his eyes. She was beautiful thought Chris. From out of sight Chris heard Gruber speak up. “Ok Chris, I need to get internal readings now. If you relax this will be most pleasurable. Try not to strain, concentrate on her and go with the sensations.”

       Nervous, but distracted with the nurse, Chris settled in for whatever was about to happen. That relaxation ended when he felt the first spike of penetration in his rectum. He began to look wildly around and tense against the straps, clenching his ass firmly against the intruder. The nurse pulled him tighter into her chest and spoke up, “Relax and concentrate on me. Imagine it’s my hand and that we’re playing a little game.”

       This distracted Chris enough that Gruber was able to work two fingers inside his ass. Curving them upward he began to probe and feel around. “Ah, there we are!” Chris tensed and quivered, whatever Gruber was doing it was an intense internal feeling like nothing he’d ever known. He felt his cock throb as Gruber rubbed inside.

       “Prostate is small and dense”, Gruber continued his probing, “And… there we are… vas deferens and cowpers glands are underdeveloped. This probably accounts for his limited ejaculate release. Now we proceed with milking stimulation. Nurse prepare the cup for sample.”

       All the while, Beth and Anna were groaning and moaning out of sight. The smell of their sex and sweat was hanging in the room. Each time the machines would shut down they would whimper, beg, or cry. Chris, Gruber, and the nurses were oblivious to them though. Gruber curled his fingers inside Chris and began rhythmically pumping them against his prostate. Chris shuddered and moaned. For some time Gruber remained slow and repetitious with his rubbing, noting to the nurse that he could feel swelling in the glans and that they were clearly building with fluid. Finally he picked up speed and pressure. Chris strained against the straps and cried out, “Ahhhhhhh!!!  Ahhhh!!!!! Ahhhh!!!!”

       “The cup”, Gruber said. With deft skill the nurse maneuvered the cup under the head of Chris’ penis while holding his head tightly. Her gaze never leaving his clenched face. With a final whimpering cry Chris flexed his body against the straps and a wad of hot cum shot out into the cup. This only encouraged Gruber to increase his speed and pressure, forcing jet after jet of ejaculate out. For Chris it seemed to go on forever – an orgasm but only limited pleasure, as no one would touch his cock. Finally, seeing no more cum oozing out Gruber pulled his fingers from inside Chris, who’s sweat drenched frame collapsed shuddering against the chair.

       “6cc’s this time. Clearly there is room for huge improvement, but thankfully you have come to the right place.”, said Gruber patting Chris on the thigh. He instructed the nurses to turn off the machines and un-wire the women. They did so right after another orgasm was denied them, leaving both Anna and Beth begging for release. “Please! Please!!!!”, shouted Beth.

       Gruber walked over to her and examined her nipples. “Almost one inch and quivering.” He leaned down and blew across one of them causing Beth to groan and jerk. “Clitoris is enlarged, red and throbbing, nearly 10ccs of fluid emitted from her vulva.” He glanced up at Beth’s face, “You are going to do great here Beth.” He then walked over to Anna and noted that her tension was clearly a sign of great things to come.

       The nurses walked over to each girl with a large glass of water, which they greedily gulped down. Then before finishing the last sip the glasses were pulled away and a large blue pill was shoved in their mouths. Anna went to spit hers out but the nurse placed her hand over her mouth in anticipation of such a reaction. “Please cooperate and take the pills, if you don’t we’ll give the medications to you another way that will be less pleasant. It’s an important part of your time here.” Realizing they couldn’t win the battle both women relented and swallowed down the pills with the last of the water. Chris, still delirious from his milking swallowed the water and pill with no complaints.

       “Nurses please unstrap them and escort them to their room. Explain to them what the pills are for and the room rules. I have other subjects to attend to.”, and with that Gruber briskly walked out of the room.

                       End Chapter Three

Chapter Four

       After being unstrapped the three were led by the nurses through a double set of swinging doors and into an adjacent room. Walking unsteadily and quivering the three looked disheveled, tired, and confused. Inside the new room sat a huge tank filled with a pinkish liquid. It was easily 5 feet deep with metal stairs leading up both sides. The nurses guided Anna, Beth, and Chris to a set of stairs and stopped them.

       “We need you to all three walk into the tank and submerge yourselves to your necks. Stay inside till we tell you to get out.”, said one of the nurses.

       All three entered the tank as commanded and stopped. It was warm, slightly viscous liquid. They all stopped and stood crouched so only their heads were visible. After a few minutes they noticed a tingling sensation that rapidly began to burn. It wasn’t a terribly painful burn, but rather uncomfortable. Beth gasped a quick intake of air, and Chris winced. With that the nurses instructed them to raise and exit the other side. As they climbed out and went down the stairs the gooey liquid slid off, leaving them shiny as it rapidly dried on their skin.

       “This way.”, said the nurses as they led them through another set of double doors at the other side of the room.

       These opened into a long hallway. The walls tiled mint green like a hospital with rows of doors along its length. As they walked past the doors Anna noted they each had a whiteboard with sequential letter number patterns. A1, A2, A3 and so on till the end of the hall… 10 in total. At the end of the hall they turned a corner to another hallway the same as the last. Walking down the hall they passed B1, B2, B3 and finally stopped at B4. The nurse opened the door and motioned for them to enter.

       Inside the three were lined up again and given a chance to take in their surroundings. There were three tables in the center of the room. Each padded with white vinyl. They looked like massage tables but there were three holes cut out. Again Anna noted the straps hanging from their sides. At the far end of the room was a half wall with a sink and toilet and a standing shower beside it. The walls were covered in white tile and the floor in white linoleum. In fact, everything was very white and very sterile looking.

       “This will be your room. I’m sure you are all smart enough to deduce the rooms you passed belonged to other recruits – so don’t think you’re alone in this experience. During the day and as needed you will partake in our experiments. When you are not needed with the doctor you will spend your time here. Each day you will be given time for one shower and one bowl movement. Otherwise you will be on these tables.”

       Anna and Beth were led to the two outside tables and placed face down. Their head went into a padded section just like a massage table, but their breasts drooped through two of the holes and faced the floor. A third hole opened directly under their sex. Legs spread slightly apart the nurses proceeded to strap them both down – restraining them at the head, elbows, wrist, back, waist, knees, and ankles. Chris was fastened down to his center table in the same manner. Once in place the nurses brought over bowls from a cart outside the room and fed them. It was textured and thick, must be oatmeal thought Chris. Then they were all blindfolded.

       “Now we want you to sleep for a while. I know you ladies are humming with tension and fear, but it’s important you rest.”

       With that they heard the door close and the room went silent except for the buzz of a florescent light. None of them bothered to talk and eventually the strain and stress of the day took it’s toll as they lulled off to sleep.

       Anna’s sleep was fitful. The throbbing ache of need continued to pulse from her clit and nipples. Her dreams were filled with Chris… his lips on hers, his hands, his cock. Beth was deeply dreaming of fucking Anna, and Chris was lost in a three way with the nurses. Suddenly they were awakened by the sound of the doors opening.

       “What’s happening?!”, awoke Anna with a start.

       “Oh God I’m so hot!”, cried out Beth.

       Nothing else was said and all three could only hear the sounds of feet moving around the room. Next they heard a stool wheel over to their left sides and then they felt hands. Anna jerked as both her breasts were cupped and rubbed. Whoever was rubbing them had sticky hands… it felt like molasses. The hands then trailed down to her crotch and began rubbing over her mound. Meanwhile Chris felt the same sticky sensation as his rock hard cock was tugged and massaged. `Shit! Is it always hard now?’, thought Chris. Beth was also being rubbed and letting out small moans as she was touched. The hands continued into their slits and over Chris’ testicles with particular attention being paid to their clits and his tight head. It was incredibly frustrating as none of it was vigorous or attentive enough to bring them any relief. After a few minutes the stroking stopped the stools rolled away and the three were left alone.

       Then it began. Subtle at first but with growing intensity all three felt a tension and ache in the recently rubbed areas. It was dull at first but quickly built to a heat and intensity. Beth and Anna could feel their mounds swell and lubricate. Their clits grew hard and throbbed, almost trying to force their way up into a full erection. Their nipples quivered and pulsed with every heartbeat. Chris could feel his cock hard as a rock. It twitched and bounced back and forth looking for something to touch. It was maddening.

       The sensations continued unabated, all three sweating moaning and begging after a short while. Straining against the straps they cried out for help, to be released from their bonds, for anything to make it stop. All they could think about was their bodies and their desire. Even reserved Anna, who had only had two boyfriends, was willing to fuck anything with a pulse… anything to help calm her down. After what seemed like eternity the doors swung open again and the sound of feet entered the room.

       “Please! For God’s sake… touch me! Get me off!”, screamed Beth.

       “Touch it! Oh…. Pppp…pppp please touch it!”, moaned Chris.

       Anna merely continued straining and struggling against her straps. Again they strange sticky goo was applied, and again they all cried and begged when they heard the stools wheeling away. To their delight they heard them wheel back up a moment later.

       A nurse spoke up. “We hope you have been resting.”, said the nurse sarcasticly. “We are going to take things a step further now…”

She was cut off by Beth, “THANK YOU! OH, THANK YOU!”

“Don’t thank us yet. What we’re about to do is going to hurt. I’m not going to lie…it’s going to hurt a lot, but it’s part of your time here.”

Anna jerked against her bonds and screamed, “LET US GO!”

Her scream was ignored and all three felt hands against them again. Beth and Anna felt fingers pinch their left nipples hard. They cried out but before they could even crescendo the pain multiplied. A needle was driven directly into each nipple followed by a heated sensation that coursed throughout their breast. The procedure was repeated on their other breast leaving them both wailing straining and sobbing. Chris who could hear their cries but was unaware what was happening to them felt a rubber sleeve pulled over his cock. It was form fitting but must have been weighted because it was heavily pulling his cock down toward the floor. He then felt a cold metallic sensation cup is balls and over his pernium. A hand was placed on his ass pressing down firmly then he felt a mouth close to his ear.

“Sweetie. This is going to hurt like nothing you’ve ever experienced. We’re sorry, but it has to be done. Bite down on this rubber stick and feel free to scream if it helps.”

Chris started to protest as the stick was thrust in his mouth, and with that he heard a click beside him. A pain like thousands of stinging bees shot through his cock as dozens of needles thrust from a metal casing surrounding the rubber sleeve and deep inside him. He screamed at an octave and tone unlike anything heard by Beth or Anna before. It was wild, visceral, and terrifying. The pain slammed through him followed by a burning in his cock then it began to swell feeling as though it would burst. Chris screamed again but suddenly it changed pitch – high and soprano. Needles had thrust from the metal casing deep inside his testicles. They were injected with the same burning liquid and felt like they were on fire from the inside out. Additional needles thrust deep through his pernium and into his internal glands. Chris passed out from the agony.

With that Beth and Anna began begging again; promising to do anything Gruber or the nurses wanted. They were ignored and instead felt fingers on their clits. They cried and struggled against the straps then screamed. “AAAAAAAAAAAAAAAAA!!!!!”, screamed Anna as she felt the needle pierce through the tip of her clit and deep inside along its shaft. As it went the burning sensation moved with it… deeper and deeper inside. It felt as though her clit was seared on a grill. The same was occurring to Beth, who like Chris passed out. As quickly as the agony began it ended, and the pain with the retracted needles.

Anna, the only one still conscious laid sobbing on the table as the stools rolled away from Chris and Beth. The one beside her lingered and she felt the gentle stroke of a hand on her head. “There, there… I know it was horrible, but it’s over. You’re going to feel funny for a while where the needles stuck you. We’ll be back soon to unstrap you three and bring you to the observation room. You’ll like it there.”

With that the stool rolled away and Anna heard the nurse exit the room. Alone, scared, and confused Anna started to hate herself for signing the contract. It wasn’t long though before her thoughts turned to her breasts and her clit. They were erect, swollen, and twitching again… begging for release as though none of the pain had ever happened.

END Four

Chapter Five

What must have been hours passed. Beth and Chris remained silent and motionless, still passed out from their agonizing experience. Anna though remained fully conscious and intensely aroused. The need for sex, for manipulation, for outright fucking dominated her every thought. She never imagined her body could feel such intense need. Though she couldn’t see it she knew she was extremely wet. And her breasts… she usually forgot they were even there, especially with how small they were, but they screamed and throbbed to be touched. Anna occasionally willed her mind to think a coherent non-sexual thought. She’d fleetingly wonder what was injected in them, what had happened to Chris, whether she could escape, then her mind would again be consumed with lust.

Finally she heard the door open again and the shuffle of feet. Instinctively she screamed in terror, which woke up both Chris and Beth. Hands grabbed her arms and the straps confining them were released. Immediately they were pulled together and cuffed together at the wrist. Then her other bonds were released and she was stood up leaning against the table.

The process was repeated with Chris and Beth when finally a male voice spoke up. It was Gruber, “My nurses say you all have been doing very well. You understand why we had to bind your arms again. Can’t have you trying to quickly give yourselves and orgasm.”

Beth shouted out, “Let us go!”, and began sobbing. Then Anna spoke up, “What did you inject us with?! My breasts… what did you put in them?!”

“All will be revealed momentarily”, Gruber said reassuringly. “I know you want manipulation and release more than even freedom at this moment. Your blindfolds will remain on for the time being and you will remain cuffed, but if you allow the nurses to lead you to the final step of intake you will be granted your well earned respite.”

Desperate, exhausted, and confused all three were taken by the arm and lead willingly out of the room and down a corridor. At the end they momentarily paused then passed through a door and into a new room. Blindfolded, scared, and over aroused the only thing they all knew was the floor was soft and padded. It was like walking on a bed.

Finally they were all stopped and turned to the left. Shoulder to shoulder they again heard Gruber’s voice though it was more booming and slightly distant. “When your restraints are removed you will leave your arms at your sides, look up at me, and remain still until I say otherwise. Do you understand subjects?” All three said yes, resigned to whatever fate was coming. The restraints were removed and their arms dropped by their sides. Then their blindfolds were taken off. The amazing brightness of the room blinded them for a few moments then winking they made out Gruber and their surroundings.

He was standing 8 feet above them behind a metal railing in front of stadium seating. Behind him were half a dozen rows of seats filled with men and women in suits, some with lab coats over top. The floor they were standing on was quilted and sheeted like a large bed, as were the walls in every direction. Everything was stark white. Seeing the surroundings and the people all staring Anna instinctively went to cover herself, but her body wouldn’t let her. Damn nanobots she thought to herself.

Gruber again began to speak as two of the nurses moved over beside Beth. “Ladies and gentlemen you will find in front of you our subjects from B4.  Left to right we have Beth, Chris, and Anna. Each has undergone the first 5 days of intake very well. Beth came to us responsive, sexual, and with average organs and build. She will serve as a control. Chris is 6 inches by 2 inches when fully erect. He releases only a minimal amount of ejaculate and has a history of erectile dysfunction. Anna, the black haired waif on the end has limited experience and has been very inhibited sexually. Now please look through your clipboards as we discuss the dimensions and organ issues each faces going into the experiments.”

Anna, Beth, and Chris were depressed and ashamed. They couldn’t will the bots to allow them to look away, but they could express sadness and shame. As the dimensions of her clitoris and nipples were described and discussed in detail tears welled in Anna’s eyes. She couldn’t imagine a world people would do this to one another. But even in their deepest despair though they couldn’t quite shake the intense feelings of lust and need. It made even Beth feel more ashamed, especially as she could feel the dampness running down her thighs from her loins.

Suddenly they all were brought back to the moment as Gruber addressed them directly. “Subjects, what you see behind me are the investors, doctors, and researchers working and backing our projects. They are fascinated with the potential you all hold. Now some answers. The dip you were placed in after your intake contained a hair removal agent. As you can see by looking down… yes look down at yourselves. Every hair follicle from the neck down has been permanently killed. We need you sleek and smooth for our experiments and believe that our removal process will soon benefit millions currently suffering through waxing and electrolosis.”

Chris gasped upon seeing his sleek new body, though Anna and Beth seemed little phased. Gruber continued, “ The gel is an androstenedione based lotion. We have been working on perfecting it’s properties to target the regions it is applied only. The end result we will learn through our experiments with you, but it is hoped it not only increases sexual response and desire, but also size and function. The pill you were given after initial intake was an activator, it suppresses certain chemical reactions from your hormones and body that would otherwise negate or half-life the androstenedione.”

Beth and Chris were lost, but Anna who had worked in pharmacology grew pale and trembled, these were major experiments and they were the lab rats.

“Finally we come to the injections”, Gruber continued. “ The injections are the major catalysts for everything occurring or about to occur to you. Alone the androstenedione would have minimal effect as we learned with A1 and sometimes negative effects as we learned with A2… poor bastards actually reversed genders.” Beth screamed at hearing this. “Relax Beth, we’ve progressed far beyond that. The injections contained stem cells primed for the organs they were injected into. In conjunction with the pills, stimulation, and the gel they will begin to grow and change your bodies into what we hope will be the ultimate in human sexuality. Of course there will be several more procedures before we can get to a point of knowing.”

Part of Anna wanted to collapse and faint, but her mind was constantly clouded with the throbbing need. Even Chris, though mortified, still maintained a raging erection.

Gruber pointed at them, “If we can perfect the growth, manipulate and change the size of sex organs, and chemically heighten desire we will all make billions in the pharmaceutical market – which is why you’re all being handsomely compensated. Though I would bet you’d give it all up for a chance to cum right now?”

Beth shouted out, “Oh Please! Please let us cum!”

“See how effective things already are!”, Gruber tittered as the audience laughed.

“It just so happens this room is designed to grant you your request Beth. We need to see where you all are in sexual need, ability, climax and desire before we enter experimentation. Accordingly please look at the screen on the wall below me.”

All three looked down as it flashed to life revealing an image in black and white line drawing of a woman soul kissing a man. Beth panted.

“We want the three of you to enact each position and picture as it flashes on the screen. You are welcome to cum as much, as loud, and as intensely as you need during this time but each time Chris needs to cum you need to place it in the cup the nurse is handing Beth.”

Chris and Beth looked primed to maul each other and even Anna couldn’t help but flush and squirm at the thought of intimate contact – even if it was in front of a dozen people.

“Notice at even the suggestion of coitus Chris’ erection has swelled. The head is purple tight and shiny with a bead of pre-cum already forming on the tip. Look over at Anna, her thighs are slick with her lubrication dripping down, her breasts flushed red and nipples twitching. Our subjects are already showing the possibilities we are creating here.”

A picture flashed up on the screen of a woman sucking the nipple of another woman. “Anna, please begin the release session and follow the picture.” She hesitated a moment, she needed and wanted release, but so many eyes were watching her. Finally, her hormones got the better of her and she walked over to Beth. Leaning down she took her rock hard left nipple into her mouth and began to lick and suck. Beth wrapped her arms around Anna’s head and threw her head back. “Oooooooo”. Anna continued then kissed over to her other nipple continuing the act. Intensity was building inside Beth’s loins. Electricity was flowing from her nipples to her clit as she involuntarily thrust her hips forward and her leg muscles tightened. Chris was whining, swaying on the balls of his feet and waiting to jump in. As Beth neared her climax Gruber spoke up. “Same picture, Switch!” Anna slowly pulled her lips off Beth’s nipple with a slurping sound as Beth grunted and whimpered. She then leaned forward and took Anna’s nipple into her mouth. With her tiny A cup breasts though, Beth easily sucked half the mound into her mouth. Anna cried out, “Yesssss!”. She rocked on her feet, her labia slightly gaped and lubrication leaking out down her legs. She wanted Beth to keep going to make her cum.

A new picture flashed up on the screen. “Switch!”, yelled Gruber. Looking over they saw the image of two women stroking a man’s cock. Anna and Beth moved over and knelt down in front of Chris. Looking directly at Chris’ cock and balls Beth and Anna panted. They wanted him inside of them, probing them, filling them. Beth moved first and grabbed hold of Chris’ cock. He jerked and gasped as she took hold of his throbbing member. Anna wrapped her fingers around the base, her other hand cupping his balls. Beth began to slowly pump, his pre-cum helping to lubricate the shaft. Within a few strokes he was grunting and thrusting forward to meet her hand. Anna leaned in closer, her breath streaming across his tight head… she wanted him in her mouth. It wouldn’t be long before he shot his load but suddenly another picture flashed on screen. It showed a woman on her back with another woman on all fours fingering her. Bringing up the rear was a man fingering the kneeling woman. Anna didn’t hesitate, she laid directly on her back as Beth moved between her legs. Her fingers slid effortlessly into Anna’s super lubricated hole as Chris’ did into hers. The penetration was divine, and Anna’s hips immediately and instinctively lifted off the floor to meet Beth’s fingers. Beth thrust back into Chris’ hand crying out, “Fuck Yes!”

Fingers continued to thrust into the women’s holes, the smell of sweat and sex hanging heavy in the air and both women crying moaning and whimpering. As Beth’s thumb vigorously rubbed and circled Anna’s clit the tension built to a crescendo day’s in the making. She tensed and flexed her whole body wildly exploding into an orgasm that turned her vision black and left her breathless. “ARRRRRRRR AHHHHHHHHHH!!!” She screamed as wave after wave lurched from her pussy and throughout her body. She felt a gushing release as her gspot spammed and she squirted for the first time. Beth was close behind. “FUUUUUCKKKKK!!!!”, she screamed out, pussy clamping down on Chris’ fingers. Both women collapsed murmuring and groggy while Chris looked on dismayed and animalistic. Suddenly the screen flashed again. It showed a woman laying on her back hips elevated being fucked by a man while a woman straddled her face.

Both Anna and Beth were listless from their orgasms, but Chris was in no mood to pause. He grabbed Anna by her thighs and lifted her hips from the floor to level her sex with his throbbing cock. Beth gathered herself enough to move over and straddle Anna’s face, lowering her sensitive pussy onto her mouth. As Anna wrapped her lips around Beth’s clit and sucked Beth gasped and threw her head back, “Gwwwaaaa”, she cried out. Simultaneous, Chris thrust into Anna, filling her with the third cock of her life. He slid easily into her tight canal forcing a moan from her. His rhythm took on a life of his own as he finally built toward orgasm. Seeing Chris thrusting and the constant moans and probing of Anna’s tongue sent Beth into another shuddering orgasm, “AAAAHHHHH!” Her juices flowing with each contraction, they ran into Anna’s mouth and down her face. It was as much as Anna could take, she came again hard, her own contractions sending Chris past the point of now return. Grunting, pumping, moaning Chris cried out, “I’m… I’m…”

“THE CUP!”, screamed Gruber. Beth snapped out of it fast enough to hold the cup on Anna’s stomach. Chris pulled out and grabbed his slick cock as a torrent of cum shot out and into the cup. 12 squirts later he collapsed to his side panting. Beth, who had rolled off Anna’s slick shining face, held up the cup and looked at it’s contents. It was the most cum she had ever seen come out of a man, maybe 5 tablespoons. Then the screen flashed again.

“Continue!”, yelled Gruber. Heady, sweaty, and exhausted but still horny they looked at the screen. To Chris’ relief it only showed two women. They were sitting side by side, legs spread, masturbating their clits. Moving into position they both gingerly began massaging their sensitive clits. Gruber spoke up over the scene, “Denote, even after two orgasms and heavy stimulation their clits remain erect. Also denote the size, they are still fully erect and swollen.” Beth and Anna once again began feeling the tension of orgasm building. They began moaning and thrusting their hips up to meet their fingers. Without control Anna began grasping and massaging her breast with her free hand. Beth reached behind herself and grabbed her ass cheek. Behind them Chris was growing hard again.

As they began to plateau and near orgasm the screen flashed again eliciting a whimper from the near orgasmic Beth. This time the drawing showed a woman sucking a man’s cock on top of him in the 69 position. The man’s mouth was buried in her pussy and another woman was thrusting her fingers into his ass. Beth didn’t hesitate, she pushed Chris back, straddled his face, and lowered her mouth to his hardening member. Gently kissing the head and moaning as his tongue licked her bud she slowly opened her mouth and sucked him inside. Chris’ cock began to swell, as Anna moved between his legs.

She had never thought about fingering a man’s ass before, but with only pausing hesitation she began working her index finger inside. It was tough, as Chris was flexing to Beth’s mouth and also resisting the intrusion. Seeing the situation Beth improvised and took Chris’ shaft all the way down her throat.

Feeling this Chris moaned and relaxed momentarily allowing Anna to slip her finger in. He grunted and strained to expel then accepted her probing. Inside she felt a large swollen lump, it was big and throbbing. Instinctively she began to rub against it. All the while Beth continued moaning and slurping his cock. Chris felt an intensity inside and out like nothing he’d ever known. There was a building need everywhere through his loins and he’d completely forgotten about licking Beth. The two women continued and picked up intensity. Beth felt his cock as rigid as steel and Anna felt a pulsing tightness from inside. Gruber shouted down, “Let him cum in your mouth but don’t swallow any of it Beth! Spit it back in the cup.”

Beth continued frenzied bobbing and sucking as Anna moved her fingers into high speed. Chris came – hard! “AWWWWWWWWWwwwwww!” He thrust up into Beth’s mouth and released wave after wave of hot, sticky, spunk. Beth began struggling with the third spurt. There was so much cum… she had to swallow. Seeing the dismay in her eyes Anna moved the cup against his shaft and Beth began to drool his load out her bottom lip and into the cup. It just kept coming, wave after wave, finally after what seemed like minutes it stopped and Chris began going soft in her mouth. The cup was nearly full and a cup in volume.

Both girls, still heady with lust looked over to the screen for further instruction, but none came. After a lengthy pause Gruber spoke up, “That will conclude today’s fucking. As you will all note the cup holds roughly 16 tablespoons of ejaculate from Chris. This will be greatly improved upon as we begin our experiments.” Hearing this Anna and Beth gasped, then looked over at Chris with concern. What the hell are they going to do to him thought Anna. Gruber continued breaking her train of thought, “Now we will offer a treat to our female subjects. Since we don’t want Chris’ product to go to waste I want you each to drink half of it.”

Holding and looking at the cup Anna gagged. She never swallowed and the sheer volume of the cup was significant. As she gagged and shuddered Beth grabbed the cup and held it to her lips. Tilting it back she began to drink it’s warm salty contents. Filling and sticking to the insides of her mouth it tasted bitter and slimy. She managed the first gulp but by the second was having trouble. Eyes squinched shut she kept slurping it down till it was half empty then she licked her lip and handed it to Anna. “Your turn. You might as well start drinking, we don’t want to upset them.”

Chris rolled over to watch Anna hold the cup of his spunk to her lips. The smell hit her, pungent and male, Anna quickly jerked the cup away and gagged again. Then pinched her nose and held it to her mouth. She swallowed the first mouth-full. Anna tried to concentrate on something else, to pretend she was doing something different, but the flavor and texture shocked her back to reality. After the first gulp she doubled over and prepared to vomit. Beth moved over and smacked her ass hard which paused her reaction. Grabbing her head she began emptying the contents of the cup into Anna’s mouth who, with Beth’s encouragement, quickly slurped it down. After the last labored swallow, Anna nearly vomited again.

The audience broke professional decorum and began politely clapping. Gruber spoke up over the din, “Very good ladies. You best get used to such meals – they contain chemicals which will help you with your sessions. Besides we demand they occur anyway as it’s the most effective method of dealing with the ejaculate we will create.”

Hearing all this from Gruber, feeling her overworked and still wanting sex, and still tasting Chris’ jism in her mouth and throat Anna lost control. She collapsed into a fetal ball on the floor and began shuddering. How had her life come to this? What was going to happen to them now? How could she be expected to drink another person’s cum in front of dozens of other people? Beth and Chris crawled over and held her tightly. For however extreme their circumstances were, they knew they were all in this together. 

Gruber spoke up as the rest of his crowd rose and exited the room. “Nurses, please take them back to their room. Feed them two large meals, shower, and bathroom them. Strap them down and give them another lotion session then leave them to rest. Tomorrow we begin the experiments.”

Chapter Six

Strapped down with throbbing organs Anna, Chris, and Beth fought through a restless sleep. As usual their dreams were filled with lust and the erotic. During their first time strapped down the dreams had been romantic and soft now they were raging hard core. As usual they were broken at regular intervals by nurses rubbing the Androstendione gel on them, each time leaving them more horny and needing than the last. The drug cocktail coursing through them was potent. While normally the threesome they had experienced earlier would have left them exhausted and sore, it was as though it had never happened. Even more maddening to them was the waiting. Despite the chemicals and the general tiredness, the inability to know what was coming was terrifying. Each time the door opened they would jump and start in their restraints – expecting this time they would be headed for whatever bizarre experiment that awaited them.

It was clear to the nurses that Anna and Chris were the most scared. Several times Chris begged them not to hurt his cock like last time. He pleaded and whimpered when they touched him expecting the worst pain and manipulation his mind could imagine. Anna sobbed and cried. She didn’t know what to expect exactly but the pain of the needles and the humiliating experiences she had been put through made her think of the worst. She dwelled on the horror movies she had seen, picturing saws and needles.

This suspense continued on and on each time broken by fitful sleep. After several lotioning sessions the door once again opened starting them all awake. Again the shuffling moved throughout the room but instead of another erotic massage they were unbound one at a time and ordered to stand. Quivering, confused, and stressed the three wavered as they stood. Beth went to remove her blindfold but instead a nurse spoke up ordering them all to keep their hands at their sides. If they did not they would be punished painfully. It was enough to keep their terrified selves locked in position.

A nurse stepped up beside each and wrapped her arm around them. Serving as a brace they walked all three forward, through the door, and down a long corridor. At the end they were stopped and ear plugs inserted into their ears. Oblivious to their surroundings now they were again embraced and walked forward for a few dozen steps. Then Anna and Beth were led to the right and Chris to the left. It was an intricate set of turns, stops, and starts. Finally Beth was stopped and turned to her left while Anna was walked a few paces beyond, stopped, and also turned to face her left. Across the way the same scenario was happening to Chris but he was turned to face his right.

Anna suddenly felt two more sets of hands touching her and guiding her. It was taking them more work as her fear was laboring her compliance. Two sets of hands grabbed her arms and directed her backwards while another set pressed back and down on her shoulders. She slowly stepped back and through force of direction moved to sit. Blind and deaf she had no idea what they were doing to her, but she could feel cold metal on her thighs and ass cheeks. Her hands were moved down till her forearms touched the arms of the chair and then her head was pushed back till it rested against a cushion. She could feel her thighs and feet in stirrups like a gynecologists office. Then she felt them strapping her down. She went to jump up and struggle but they moved quick using force and body weight to keep her in position. She couldn’t hear anything but she knew she was screaming. They strapped across her forehead, wrists, upper arms, ankles, thighs, and hips. It happened in a flash as though they had done this hundreds of times. Before she could fully comprehend her situation she was immobilized in her seat. Meanwhile, the process was repeated with Beth.

Across the room Chris was directed forwards a few steps. Still standing he felt his pelvis come in contact with a strange gooey substance – it felt like jello. From seemingly nowhere – especially since he could neither hear nor see – he felt a board against his back. It was rigid to be sure, and he was speedily strapped down at 10 points. Besides the board all Chris was aware of was his cock and balls in the weird gooey substance. It was body temperature warm and pliant. He could feel his cock hardening and the substance was allowing it to firm up while still encasing and holding it tightly.

Suddenly their earplugs were removed and the sounds were deafening. The hum, whir, and buzz of machinery was as loud as a factory and from seemingly every direction came the moans, cries, begs, and whimpers of voices in ecstasy and pain. Over all of this they managed to hear Gruber’s voice.

“Welcome to your first day of experimentation! Everything you’ve been going through has been leading to this. Starting today we will begin changing your body physically. We will be changing the size, shape, and function of your sex organs. Sensations will be manipulated on a permanent basis, and mental processes will be tweaked. Every one of you will leave here a drastically different person than when you arrived and each of you will be given gifts that will change every aspect of your lives!”

Anna and Beth screamed louder than they ever had. Chris begged to be let go. Tears streaming down her face Beth resigned herself to her fate. These monsters were going to alter her body in extreme ways – ways that would change her permanently. She had wanted new experiences and knowledge, but nothing like this.

Gruber continued, “Know you are not alone in this, there are many other subjects also going through experiments in this room, as you can hear. I will not lie, this will not be easy but understand that in the end your contributions here will change the lives of millions of people for the better. Also understand that every person in this room is having a slightly different experience. Some are being changed differently than others, some are being transformed at different levels. The A group, who has mostly transitioned from these experiments were taken to the extremes. They were the primary experiments to see how far we could stretch the capacities of their bodies and what we could make them into. They taught us much, the unending size breasts and testicles could be increased to – yes there are limits. The amount of nerves that could be concentrated in the tip of a cock, the amazing capacity of vaginal elasticity… they were an incredible set of subjects.”

“You, the B subjects, are where we go for refinement. We know what we can create and do, but now we want to see if we can perfect some of those lessons. It may not always work out as desired but that is the price of science.”

Anna spontaneously vomited. Her skin was clammy and slaked in sweat. She had screamed again and again listening to the mad scientists’ description of his work but was finally settling on tense fear. There was no point in struggling, the straps were too tight and besides, the nanobots wouldn’t let her fight or run anyway. Chris started to yell something but was cut off by Gruber.

“Now we begin. Nurses, place the ring gags in their mouths please then remove their blindfolds so they can watch their surroundings. After that begin the machines and procedures based on your charts.” Finished, he turned and walked away, his footsteps quickly lost in the cacophony of human sounds and machines.

As the blindfold was pulled from her eyes Anna was momentarily blinded by intense light. This quickly gave way to a sight straight out of a science fiction horror. The machine she sat in was huge. She couldn’t move her head but she could tell that it’s bars, and displayed covered walls nearly surrounded her. She could still see to the front and could glance down at her naked sitting body. Her breasts were completely exposed and the pad she rested against served to jut her chest out. Her legs were completely splayed, so much so she could feel the cool caress of air against her slightly parted sex. Across the way she saw it for the first time and again screamed in terror through her gag.

It was a long row of men – all strapped to metal boards like Chris and all with their genitals encased in a strange goo filled box. The box was mounted on a large metal box and had dozens of wires running throughout it. The man beside Chris was moaning, and coated in sweat. Looking more closely at his box she could see his balls were wrapped in some strange looking set of wires. His cock meanwhile was surrounded by the most complicated and large looking metallic sleeve. It was a vision she could never have imagined. The sleeve was furiously pumping on him, then slowing down. Every time it slowed he groaned and winced then it started again. She glanced back over to Chris, unable to imagine what was in store for him in his sleeve. Looking up at his face she saw a measured expression of compassion and horror. Clearly he was looking at her and whatever he was seeing had him worried for her sake.

Chris meanwhile was scared for Anna and Beth. He could see them both across the path and their predicament looked mortifying. They were strapped to strange seats. Below them were a half dozen large phallic tipped arms. On either side of their hips on separate articulated arms were odd cup shaped implements connected to hoses that ran off behind the machines. Above and behind their heads were large cylindrical tubes connected to hoses. Further hoses had strange looking devices dangling from them behind them and at head level. Without warning lights went off around Anna’s machine. Chris watched her tense as her experiment began.

End Six

Chapter Seven – Anna’s Ordeal

Two hoses with small fuzzy brushes dropped down on either side of Anna. Eye level she watched as they flexed and turned then the brushes came to life, spinning at a variety of speeds. A slimy goo coated and dripped off of them. The hoses dropped further and the brushes moved perfectly so as to rest against her nipples. As the goo came in contact with her she felt a tingle shoot throughout her nipples. It felt like an icy/hot balm but pleasurable. Her nipples hardened like pebbles sending waves of achy need throughout her breasts; then the bristles began to spin. It was slick and soft like fine velvet with the hoses maintaining pressure against her nipples and areola. It was one of the most intense, divine, and erotic feelings she’d ever known. She strained against the straps to thrust her breasts out and felt her sex ache and throb. Anna knew she was literally dripping wet and was moaning for want of something inside.

The brushes were relentless but not enough to get her off on their own. Eyes half lidded and staring at the hot straining men across from her she was quickly forgetting her surroundings. Suddenly the hoses retracted behind her and the caressing stopped. She only had time for a quick whimper though before two articulated arms rose up. They swept forward and placed a clear cup over each breast. Hoses ran from the cups up and out of site. Anna suspected what they would do before it even occurred. As they sprang to life she again strained forward against the straps. This time it wasn’t just out of lust, she was being suctioned. As her breasts stretched forward to their maximum and Anna moaned out of mixed pleasure/pain the machine held the pressure firm. Her breasts were now fully stretched forward, only filling the cups a quarter of their capacity. The unfilled space filled with a greenish fluid, then she felt new brushes again caressing her hard distended nipples. How they got inside the cups was a mystery but yet there they were buzzing, brushing, and sending intense feelings radiating from her nipples through her body.

Anna couldn’t hear much of anything over the hum of machines and the screams and cries of the other experimentees. Worse yet, the heavy arousal she was going through fogged her mind. With all that was going on it was quite a surprise when she suddenly felt a kiss on her cheek. Her eyes shot open fully and she jerked with fear against her restraints. “How are you doing sweetie?”, asked a female. With the gag in place all Anna could do was grunt and moan. From out of view a pretty redhead nurse in blue scrubs appeared in front of her. She bent forward and leaned between the suction cups bringing her eyes level with Anna. Smiling the nurse spoke up, almost shouting, “Our readings show you’re reaching a three on the arousal scale. That’s great Anna! A highly turned on woman in the real world would register a one on our scale. Before you finish the program you’ll be much higher.”, she said with a wink. Anna groaned loudly and jerked against her restraints. “There… there…”, said the nurse patting her thigh. “For today we’re only going to take you to a four. Now I know you’re feeling a need from your genitals unlike anything you’ve ever imagined – and that’s only from the stimulation of your breasts!”

Anna began to tear up. Partly out of overwhelming sensations of sexual need and partly out of fear of what was to come. She honestly didn’t believe she could be any more aroused than she already was. “Now I’m going to begin working on your southern bits. Go ahead and cum if you want, but don’t think it’s going to bring you much relief.”, the nurse said with a wicked grin.

With that she knelt down between Anna’s legs. Another hose with a thin suction tube slowly began dropping down from above the nurse. As Anna watched its slow decent she figured out what it was for. She began to tense, her thighs quivering against the straps, waiting for it’s contact to push her into orgasm. The brushes against her nipples began to quickly flick up and down, increasing her tension even more and eliciting a cry. Drool streaming from her gagged mouth Anna was desperately trying to mouth ‘Please’.

She felt the nurses lips kiss her trembling thighs and then her fingers parting her lips. The nurse yelled up at her, “You are soooo wet Anna! That’s very good!” Then she felt it. The nozzle surrounded and sucked her clit up inside, pulling it out from its hood and halfway up the cylinder. Every muscle and tendon in her body shot ridged at once and from the tip of her clit, through her belly, and to every inch of her body an explosive orgasm tore through her. She screamed – high pitch and involuntary – as her mind went black and everything around her seemed to stop. It went on and on and on… wave after wave crashing over her being.

Whether from sheer exhaustion or some other turn of biology, the nearly painful orgasm finally subsided. After what felt like eternity Anna finally stopped flittering her eyes and opened them to see the smiling nurse. “Very good! Just imagine Anna… if you’re at a three now what will that be like at a nine?!”, she cackled almost manically. As she talked Anna could feel the arousal rapidly returning to its previous intensity. “Mercy!”, she mouthed against the gag. The nurse ignored her, leaning in close to her ear she continued to talk. “Anna… you’d best enjoy this as you can. You have soooo many sessions here before you can even be evaluated. Now the machine is going to move to the next and final phase. You’ll remain in this phase for a while before today’s session ends.” With that the nurse once again walked out of sight.

Once again Anna was straining against the straps. It felt as though the cylinder was bobbing up and down on her clit, sucking it in rhythmic time. Though she couldn’t move her head to see, she imagined it was vigorously blowing her. No lover, masturbation, or even dream had ever come close to the feelings it was generating in her and that coupled with her breasts was pushing her to even higher heights of arousal. She knew she was building toward another major orgasm then she felt her chair shift around. Not unlike a motion ride at an amusement park, the chair was adjusting and aligning her. Then she felt it against her vagina.

She tensed and jerked trying to move upward and away, but the straps gave her absolutely no freedom of movement. There was something phallic lining up with her pussy. She could feel it nuzzling between her soaking lips and could tell it was large and very solid. Finding the alignment it wanted it quickly and unremittingly thrust upward. Out of pleasurable relief, humiliation, and fear Anna screamed.

It moved fully inside, filling her unlike anything she had ever known. Then it began slow piston like thrusting. In and out… In and out… the machine was fucking her. At the same time the devices on her breasts and clit increased their ministrations. In the face of so many stimuli the violation quickly turned to pleasure and Anna once again began to edge toward shattering orgasm.

She was not prepared for what happened next. Another probe began rubbing against her anus. Anna had never been penetrated in her ass. The thought had always filled her with equal dread and disgust. Had she not been sexually worked over for days prior and had she not been experiencing the work of the machine she would have protested, tensed, and tried her best to protect her virgin ass. As it was the best she could muster was a wide eyed, gagged beg, “Eeeeaassse… Noooooooo!!!”. With that the probe began inching inside her ass. Anna squirmed against the straps and tried to expel the intrusion but there was nothing she could do. Like the vaginal probe, once it was fully inserted it began to slowly pump in and out.

She groaned and thrashed, repeatedly groaning as the vaginal probe began to pick up speed. With the clit cylinder now vibrating as well as sucking Anna’s arousal reached a cresendo. Within minutes the anal probe began to feel pleasurable and Anna was losing her last vestiges of control.

The nurse again stepped into view and leaned over close to Anna’s ear. “That’s it sweetie, ride the sensations. In a few seconds you will pass into arousal stage four. Then the machine will make you come even harder than the last time.” Anna’s whole body was quivering and her eyes were rolling back in her head. By this point she was crossing over from plateau toward orgasmic release and was nearly oblivious to the words of the nurse. “The machine will keep pushing you into orgasm after orgasm for a while with short rests in between. I’ll be monitoring your vitals and reviving you if you pass out. Enjoy it sweetie. I’ll check in at your first break.”

She leaned in and as her lips kissed Anna’s cheek the next orgasm tore through her. Her muscles contracted and strained against the straps repeatedly as she screamed and screamed.

It Begins for Chris

Firmly strapped down and immobilized, Chris was overwhelmed by the sights and sounds of the room. Anna and Beth looked terrified and the multitude of apparatus surrounding them were ominous. He was scared for his own predicament and worried about them, especially Anna. Knowing her background and what she had already gone through he wasn’t sure she would be able to take this part. At best he thought she would lose her mental faculties at worst she might die. Beth, who was being shifted into a new position by the machine looked bewildered, but somehow he felt she would be able to cope with her experiment.

As for himself, he was steeling his nerves for whatever was about to happen. The box in front of him completely surrounded his manhood. This in itself was terrifying as he remembered the last time they had placed his parts inside a metal apparatus. Unable to move or clearly look down he couldn’t see exactly what was in store for his poor cock and balls. Instead he had to watch the row of poor women across from him. Between Anna and Beth was a girl of no more than 19. Blonde and beautiful she was dripping with sweat. A nurse was kneeling in front of her rhythmically and gently massaging her pussy while the machine thrust a dildo in and out of her mouth. She was in distress and although Chris didn’t know how long she had been there she looked exhausted.

Suddenly a nurse in scrubs stepped up in front of him. Placing her hand on his chest she looked into his eyes. “We’re going to start your machine now!”, she yelled over the sounds of the room. “I’ll be checking in with you throughout the evening as the procedure unfolds.”

With that she stepped out of sight and the machinery around him began to hum. The initial sensation was delightful. It felt like dozens of expert hands massaging his cock and balls. For the sexually pent up Chris it was heavenly. Then he felt his parts being adjusted. His cock was lifted up and balls pulled downward. It wasn’t painful, just the feeling of manipulation. Throughout his genitals he felt a light vibrating sensation, one that was incredibly erotic and pleasant. Then he felt a tight grip on all of his maledom and a pinching sensation at the head of his cock. Suddenly it felt like fire as something was forcing its way down his urethra. With each passing moment it pushed deeper and deeper fully probing the length of his cock.

It hurt and Chris was moaning as it moved into him. Simultaneously he felt probing at his rectum. He instinctively clenched his ass tight but the pushing was wet and relentless and the intruder moved into his ass. It was large and stretching his sphincter was painful but then it began to move around inside of him. Like a strange alien sensation alive in his ass it pushed against his prostate and probed to find his reproductive glans. Meanwhile the penile probe had worked inside past his cock. Like a worm it was snaking up into and past his prostate. He could feel painful and odd sensations deep inside in places he had never felt, then it stopped.

As the probes completed their penetration the pain subsided and was replaced with the most intensely pleasurable feelings his cock had ever known. He could feel his prostate being stroked causing waves of internal pleasure to radiate from his core. His cock felt as though dozens of vibrating tongues were licking it from all directions. Within moments he was straining and grunting.

The nurse stepped in front of him again and began stroking his chest. “It’s o.k. Chris. We want you to release and cum for us. Let it go sweetie.”

With a loud moaning cry Chris felt himself ejaculate. Wave after wave of pleasure crashed over him as jets of hot cum spewed forth. As his final spurt shot through the tubes and out of him he suddenly felt an incredible, terrifying, and unexpected sensation. Fluid was shooting back up the tubes and filling him up again. Filling and stretching the capacity of his prostate and other glands and filling his balls from within. It was not pleasurable but not painful in itself. What it did do was elicit a gasp from Chris and forced his body into shaking spasms.

The nurse spoke up again, “The machine is filling you back up with your ejaculate Chris. Your expelled cum is mixed with more stem cells and other chemicals that are being absorbed by your organs.” Chris was only half listening.

“As this procedure is repeated over and over your parts will expand and change. You will fill with more and more ejaculate, over time creating the volume the Doctor requires. You’ll also refill with that huge volume very quickly so within minutes of cumming you will be ready to shoot another equally large load.”

Chris couldn’t believe what she was saying and could only partially concentrate on it. He wished they would just let him go, he didn’t to go through this. At that instant, as he felt internally filled to capacity, the machine ceased injecting him and began the pleasurable sensations again. Within moments he again expelled another huge ejaculation, this one longer, more powerful, and with more volume than before.

The nurse continued stroking his chest. “Oh baby that is soooo good. You are doing so well! Here’s a secret I’m not supposed to tell… If I do a good job transforming you I’ll get to occasionally test you out!” Chris looked down at her and could see giddy glee written across her face. “Not only will I get to try that ever rigid spunk filled cock of yours but the machine is stretching it, growing it, and transforming it to the proportions necessary for all that cum. We’re talking 11 inches long with balls the size of oranges!”

Chris shut his eyes tight as again the cum serum was flooding back up inside him. What nightmare was this! Modified, manipulated, and pimped out to this perverted nurse all while watching Beth and Anna, the two people he cared about most, suffer and struggle. Chris whimpered and began to tear. He wanted the nightmare to end but despite his desires the machine continued on pumping and extracting.

Breaking Beth

With the cacophony of sounds around the room reverberating in her ears Beth glanced over at Chris. He seemed uneasy and the nurse with him very interested in his reactions. If she didn’t know better she would have sworn the nurse had an unprofessional interest in him. As she contemplated the upcoming session she thought on what Gruber had done to her so far. All the chemicals, serums, and devices were clearly changing her. She had always been easy to arouse and had larger than average breasts but these changes were obviously manipulating her. She was always so horny now. In fact, there were few things she could think about anymore besides sex. She wanted carnal interaction constantly and when not otherwise engaged thought the most perverted thoughts. Her breasts were clearly growing and her body becoming more sensitive and quick to respond.

As she contemplated her ordeal her nurse walked right up to her. A pretty black girl with a mischievous grin and shapely figure, Beth instantly recognized her for the hotness she exuded. Leaning up cheek to cheek with Beth the nurse’s hot breath cascaded across her neck. “Hello Beth. I’ll be assisting you throughout your transformation. Some of the nurses here are sadistic, others are coy, I am clinical and direct. I’m not going to lie to you about this process, it is extreme and you are going to cry. Sometimes it will be from pain, sometimes from pleasure, mostly it will be because of the changes inside you. Remember, no one can or will help you. You volunteered for this, and you will adapt.”

With that the nurse kissed her cheek, pulled away and pulled a lever to the side. Beth’s chair rose up a couple of feet then tilted forward. It stopped when she was 60% forward, her weight hanging toward the floor. Pushing another button the strap below her chin pulled upward keeping her facing forward. Beth could no longer see her body as it hung down toward the floor. Pulling another lever the nurse turned her gaze toward Beth’s face and watched intently.

Seconds later Beth felt her breasts being encased in cold metal. She jumped at the chill, and with fear. She watched, quivering with anticipation as the nurse walked out of view. Then she felt it. It was a tightening feeling on both breasts. There was the feeling of gentle tugging then intense pain. She screamed and jerked against her bonds as she felt each globe stabbed from several directions. It was the same agony she had felt that day in her room when strapped to the table. Then it stopped and the gentle massage began again coupled with a strange wet and slimy feeling.

As the moments passed the massaging sensation became more and more intense. It felt as though her breasts were vibrating and being lavishly sucked. Her nipples were being manipulated and vibrated. It was something unlike any previous experience and it was growing from deep inside her breasts. A pulsing sensation then the throbbing tingling sensation she had only felt before from her clit. The moments passed and she couldn’t help but watch Chris across the room. He was slaked with sweat and straining, screaming, and relaxing over and over. Normally it would have been horrifying to watch, but with all the manipulation and chemicals Beth was finding it highly erotic.

As the time passed Beth became ever more focused on the feelings from her breasts. The sensations were amazing. The normal pleasure from her breasts was enhanced with the increasingly powerful new sensations. As best as she could describe it her two chest clits were being manipulated with deft skill by the machine and she was feeling an explosive intensity building in her chest. Her breath labored and she began straining and twitching. While she found she wanted something to touch her hot and aching pussy she mostly wanted her breasts to be stroked.

Nearing her release Beth felt a hand on her cheek. Her eyes shooting open she saw the nurse in front of her. “Ooooo”, Beth groaned. The nurse leaned forward and spoke up over the machine. “How are your breasts feeling dear?” Beth moaned and grunted again. “That’s excellent. Too many women do not get enough pleasure from their breasts and you are going to help us change that.”

The nurse leaned down and adjusted something out of view. Beth tensed as she felt the vibro-sucking sensations on her nipples intensify. “When this is all done you are going to have some of the most pleasure sensitive breasts on the planet Beth. You’ll forget all about your genitals and focus all this pent up lust on your chest. Now get ready to feel your new orgasm.”

With that the massage shifted to high gear and Beth felt the tension in her breasts crescendo, then explode. An orgasm burst forth from her breasts with the same crashing, pulsing, intensity she had only ever known from her pussy. “Fuuuccckkk”, Beth screamed. Her body shook and jerked as she yelled.

Soon it ended and she hung limply, gasping for breath, feeling the tingling pulse throughout her breasts as she had so many times in her post orgasmic clit. Then the massage began again.

Evaluation

The sessions passed one after another. After each round at their machine Anna, Chris, and Beth left so exhausted they had to be carried to their rooms. After a while they blended together and their bodies were left in a constant state of tension and release. They were exhausted, but the sadistic doctor clearly had an agenda. They had all noticed changes in each other as well. Anna’s organs had grown noticeably, as had Chris’. All of them were much more responsive to touch sensations and their orgasms had grown increasingly intense; more intense than any of them had ever imagined possible.

It was impossible to judge which session they were currently on, but following restraint in their respective devices, the three were shocked when they didn’t start up like usual. Instead they saw Gruber step into the center of the room.

“My dear subjects, I want to congratulate you all on how far you’ve been coming in such a short time. You are all changing in such wonderful ways and progressing nicely. With that in mind we have a special day before us.”

The subjects lining the rows were watching him intently. Nothing he was saying was very reassuring. In fact, it was terrifying, as every time Gruber said the word special it seemed to mean some sort of new change or agony.

Gruber continued, “You may have wondered what the strange light emanating box is in the center of the row. Well you are about to find out as we have two potential graduates today who will demonstrate their changes to you. Their readings to date have shown they have achieved the desired changes we seek. However, those changes have been calculated with their machines. We require real world demonstrations in the manner they will experience in the future. If they pass they will graduate from the room and head to newer and better things. If they fail, it is back to the machines for more manipulation and change.”

As he spoke a pair of nurses were leading two people to the light box in the center of the room. One male and one female, both looked worried and charged to complete their challenge and graduate.

“Here we have Yuki and Fritz,” Gruber said.

Leading Yuki to the box two nurses arranged her up on her knees, legs spread slightly facing toward the male row. A beautiful Asian girl, she was also quite dainty, no more than 5 feet tall and less than 100 pounds. Her wavy black hair swung past her shoulders and her sleek body glimmered from the lights emanating from below.

“Yuki has been through 200 sessions. To the eye she looks the same as the day she arrived, however with luck we will all see the success we have had with her internally.”

The nurses pulled her down and replaced Fritz in the same manner but facing toward the girl’s row. Beth gasped at seeing him – he cock was huge and it wasn’t even hard. Clear precum was dripping from the tip and his balls were easily the size of lemons. As she ogled the nurses began stroking his member, hardening it quickly. With each stroke it grew until it’s full length, easily 10 inches long and 5 inches thick, stood at throbbing attention. Then they pulled him down to standing position and pulled Yuki back up on the box. They arranged her on all fours facing the women and led Fritz behind her.

“Now we will begin your evaluation. You will fuck in the positions we indicate and you will not stop until I say. Enjoy your test!” Gruber and the nurses stepped away as the two subjects waited with anticipation. Yuki was already wet, her juices dripping onto the table below her. Fritz’s cock glistened with precum.

As the two waited the rows of machines holding the watching subjects hummed to life. Within moments they began their usual straining, orgasms, and manipulation. This time however they were watching Yuki and Fritz.

“Vaginal intercourse Fritz,” said Gruber.

Leaning forward Fritz began trying to penetrate Yuki. While her wetness should have made it simple his size was causing some frustration. Gripping her hips firmly he pulled her hard back against him and pushed his throbbing head past the tight resistance. Yuki let out a painful cry then whimpered as he began burrowing in deeper. When he felt her jerk as he bottomed out he pulled back then began a steady rhythm.

Pain quickly turned to pleasure as Yuki began thrusting back against him. Within moments she jerked and cried with a powerful orgasm. She would have collapsed had Fritz’s tight grip not held her hips up so he could continue his thrusting. A few thrusts later her head flew back again and she screamed as she came a second time.

This continued for a short while until Fritz began to pick up speed and grunt. Overcome with the intensity of the situation he had lost sense of Yuki’s pleasure and pain and slammed forward with all his might. Yuki screamed out in pain as his cock head crashed against her cervix then he released. For all watching his orgasm seemed to continue for an eternity. Within seconds white froth was pulsing out the sides of her vagina and splashing on the table below. Seeing this one of the new girls on a nearby machine became ill.

As his marathon cum began to subside Gruber stepped to the sweating, quivering couple. “Good, now to test the machine’s changes on Yuki. You see everyone, we hadn’t even manipulated her genitals during her sessions, and poor Yuki here knows what this evaluation is about for her. She has had dread in her eyes since she was led to the table, but I promise she will find it immensely pleasurable.”

Gruber stepped away then shouted over the sounds of the room, “Fritz, anal now.”

Yuki steadied and braced herself as Fritz’s still erect and turgid member brushed against her sphincter. There was no need for lube, the amount of ejaculate dripping from his hard cock was enough to wet the entrance.

With pressure his cock began sinking into her hole. Unlike her vagina that had provided some resistance her ass opened itself up. In fact, it seemed to Fritz as though it was trying to swallow his cock whole. Each inch sinking in deeper elicited new cries from Yuki. Despite his size and vigor they weren’t cries of agony. Rather, Yuki was clearly cumming from her ass – hard and repeatedly. Once all ten inches were buried fully inside she looked back over her shoulder and with a stern face said something in her native Japanese.

Gruber gleefully spoke up, “My dear Fritz, she says hard and fast.”

With that Yuki lurched forward then slammed back against Fritz, expelling and swallowing his entire member inside her ass in one quick movement. He grabbed her hips and together they entered a rapid trance like pace of slamming his huge member inside her ass. She came, over and over – harder each time. Shortly Fritz came again and Yuki cried out in ecstasy feeling his spunk splash throughout her.

Then she flipped over on her back, pulling Fritz into missionary. He continued pummeling her ass, cum splashing out with each thrust and the table glistening with sweat. He was again nearing his climax when it happened. Yuki screamed out in obvious pain rather than pleasure. Gruber came dashing up to watch more closely, he was obviously concerned.

Grabbing Fritz’s ass Gruber directed harder thrusting and watched as Yuki began writhing, struggling, and screaming in pain. He allowed Fritz to finish inside her again then directed him to slowly pull out. His cock head, swollen and an angry purple color, pulled out of her anus with some effort resulting in a popping sound. The nurses pulled her shaking form into a sitting position resulting in steady cum flowing from her ass and coating her thighs and the table in a pool nearly an inch deep.

Sitting in Fritz’s cum, shaking, and gently crying Yuki anticipated what was going to happen even before Gruber spoke. “Yuki, you have failed the evaluation. Since your recruitment in Kyoto we have been grooming you and testing you to become our anal success story. Your anus has been manipulated and filled with more pleasure nerves than any other part of your body, it has been stretched and made self-lubricating. The response to pain instead of pleasure then is problematic. We must continue your experiments.”

Gruber waved for the nurses who grabbed the sobbing Yuki be the arms and legs and began carrying her back to her machine in the row of women. Her screams and cries for another chance were ignored and soon the hum of her machine added to the sounds of the room.

Gruber turned to Fritz and smiled. “You have passed my dear man. Your volume is satisfactory and your lack of a refraction period is a resounding success! Please follow the nurses to your room.”

With that Fritz disappeared out the doors at the end of the corridor and Gruber turned again to the rows of experimentees. “My dear subjects, you have just witnessed the culmination of your experiments. While you are all being changed in various ways in the end you will either succeed like Fritz or suffer poor Yuki’s fate. Remember, it is not her fault, rather the experiment has not fine-tuned her biology yet. Soon enough she will be given another opportunity and when she succeeds can rest confident in the joy of her newly transformed self.”
