Chapter Twelve: Brotherly Love (Mandy)

(m/f, spanking, bdsm [light], sex, incest, cons)

It had been six weeks since that awful night when Mandy's parents had made her strip naked in front of Steffi's parents, and then spanked her while they watched. She shuddered, remembering how they had then allowed Steffi's father to spank her and whip her with a big, heavy razor strop. That had been the worst punishment Mandy had ever gotten. And, to make matters worse, Steffi's dad had an obvious boner the whole time!

Still, there was a good side to the whole situation. Afterward, her parents seemed to have realized that they had gone too far in letting Mr. McAllister punish her so severely. And, though they believed in shaming her by making her disrobe for some spankings, they had apparently decided that humiliating her in front of other people had been the wrong thing to do. The result was that Mandy had not gotten a single spanking since that night. That had made her happy. She had hardly been able to sit down for about a week after Mr. McAllister whipped her, and it had taken almost three more weeks before all the marks faded away.

On the other hand, Mandy was starting to get very horny and frustrated. Her parents left her alone, but so had Rick. Mandy thought that he must feel sorry for her too, and that's why he hadn't approached her lately. Sure, there were a number of boys she knew whom she could have seduced, but she hadn't wanted any of them to see her marked bottom. So after six weeks with no sex, Mandy was a little tense.

That was going to end tonight, though. Her parents had gone away for the weekend, leaving Mandy home alone with Rick. He was in his room right now, and Mandy was in hers, standing naked in front of her full-length mirror.

Mandy had a plan. She opened her underwear drawer and found a little leopard-print thong panty. When she had put it on she turned her back to the mirror and looked over her shoulder at her reflection. Satisfied with the way the thong showed off her butt, she took out her new bra and put it on. It was black and lacy, and the top edges of the cups barely concealed her nipples. Pads in the cups pushed her breasts up and made them look a bit bigger.

Next, Mandy pulled on her shortest, tightest miniskirt, a little red spandex number. She adjusted it as short as it would go, until the hem was just barely lower than her crotch. Again she studied herself in the mirror. The tiny skirt showed off a lot of leg, revealing just enough to pique the imagination. Satisfied with the skirt, Mandy topped everything off with a white, cropped tank top. The shirt left most of her midriff bare, and was nice and tight so that it molded itself perfectly to her breasts. While studying herself in the mirror one more time, Mandy briefly considered putting on a pair of spike-heeled sandals, but decided to just leave her feet bare.

Ever since she had discovered her brother's cache of porn videos, Mandy had taken every opportunity to secretly watch the movies and study the things the actors did. She had masturbated furiously along with the onscreen action, bringing herself to multiple orgasms every time, but it wasn't enough. She needed a cock. Because Rick had never made her come, she had paid special attention to the scenes where the same guy had orgasmed more than once. She had already seen how a guy could fuck one girl, take a break and then fuck another girl a few minutes later. She had also watched a few scenes where a guy fucked a girl, and then when he went limp the girl sucked him until he was hard again.

What especially interested Mandy was the way these porn actors would last longer the second time they had sex. Maybe, Mandy thought, if Rick lasts longer the second time, he'll make me come!

Mandy was ready. She took a deep breath and walked out of her room and down the hallway to Rick's bedroom. Standing outside his door, she waited, heart pounding. She was nervous, because she had never actually seduced her brother before. Every time they'd had sex, she had allowed him to think he was punishing her, or that she was just making a trade so that he wouldn't tell their parents about some misbehavior on her part. She had always let him think that she didn't really like it.

After tonight, he would know better.

Placing her ear against Rick's bedroom door, Mandy heard the telltale sound of a porn video playing on Rick's TV. Immediately, Mandy knew how she would keep Rick busy long enough after he fucked her so that he could recover and fuck her again. She would give him excuses to spank her. Mandy knew that Rick liked spanking her, so provoking him would be easy, but she winced at the thought of how much spanking she'd have to coax out of him, and endure, to allow enough time for his recovery. But she resolved to go through with it. She thought to herself, Maybe he's right. Maybe I do like it. Maybe he'll spank my boobs again…

It was time to get Rick's attention. Taking a deep breath, Mandy twisted the doorknob and pushed the door inward, simultaneously calling, "Hey, Rick!" As she expected, it only opened an inch before banging against somthing heavy that Rick had placed in front of it. Mandy was gratified when she heard the television click off and heard Rick cursing. She backed up against the wall opposite Rick's door, and struck what she hoped was a seductive pose.

"Godammit, Mandy!" Rick yelled from within his room. "You know you're supposed to knock before you try to come in here!" Mandy could tell Rick was mad, and she could hear him pushing something away from the door. "You've just earned yourself a spanking! Mom and Dad said I could spank you if you misbehaved! So I'm gonna…"

The door opened, and Rick stopped in mid-yell when he saw his younger sister dressed like a hooker. He let out a long, low whistle as his eyes traveled up and down her body. "Holy shit, Mandy, why are you dressed like that?" He kept staring, obviously liking what he saw. He was dressed only in a T-shirt and briefs, and it was obvious that he already had a hard-on, probably because he'd been watching porn, but in no way diminished now that he was staring at his sister. "You look fuckin' hot!"

"I was hoping you'd think so," Mandy replied. "Wanna fuck?"

Rick's jaw dropped. "I…"

"I'll take that as a yes," Mandy said, grinning. She walked toward her big brother and put her hands on his muscular chest. Then she pushed, making him back up. When she had backed him up to his bed, she gave him a push, and he fell onto his back.

"Mandy, what are you up to?" Rick asked, completely befuddled by Mandy's behavior.

"Shhhhhh." Mandy put a finger to her lips. She bent down and grabbed the waistband of Rick's briefs and pulled them down his legs and off. Pushing his legs apart, she kneeled on the floor and grabbed his hard cock with one hand. "Have I ever told you you've got a big one?"

Without waiting for an answer, Mandy went down on her brother. She sucked as hard as she could and took him all the way to her tonsils.

"Oh, shit, Mandy! Shit!"

Mandy looked into Rick's eyes as she bobbed up and down on his throbbing shaft. She was amused by the look on his face, and knew it was going to be even better in a few seconds. When she was satisfied that Rick's cock was as hard as it was going to get, she stood up. She climbed onto the bed and straddled her brother. Reaching under her miniskirt, she pulled the crotch of her thong to one side and lowered herself onto Rick's cock.

"Oh god, Rick, that feels so good!" Mandy moaned as she sank down until her pussy was enveloping Rick's whole dick. She held herself there for a moment to savor the sensation, then rose up until only the head of the shaft was inside her. Down she went again, then back up, riding her brother with wild abandon. "Oooooooo," she purred, enjoying Rick's facial expressions almost as much as the feel of his dick inside her.

"M-Mandy," Rick stuttered, "Don't forget I can't c-come inside you!"

"Just tell me when you're about to do it," Mandy gasped, "and I'll get off…" She bounced on his cock even faster, and was already nearing climax herself. I must have needed this more than I thought!

As Mandy had expected, it was only a minute later when Rick hollered, "I'm gonna come!"

Mandy immediately rose up off of her brother. Kneeling on the bed beside him, she lowered her mouth to his trembling dick. His first blast of spooge erupted before she could get her lips around him, and it splattered against her cheek. Giggling, Mandy took Rick into her mouth and caught the rest of his load.

This was the first time, she realized, that she had ever let a guy finish in her mouth. Typically, she made her "boyfriends" wear a rubber, and they would usually shoot off in the rubber while they were fucking her. In the past she had only let Rick come on her face and tits because she knew he thought it was part of her punishment. Of course, she had tasted Rick's semen before, but only by scooping it up and licking it off her fingers. She liked the flavor, and was now discovering that the juices shooting directly into her mouth produced a pleasant sensation. Mandy sucked hard, trying to coax every last drop out of her brother's dick. A moment later she felt him softening, and knew he was done.

Mandy rose back up on her knees and smiled mischievously at Rick, who still wore a dazed expression. She opened her mouth wide and showed him that she hadn't swallowed — her mouth was full of his juices. Rick looked on in surprise when Mandy closed her mouth, swallowed dramatically and then opened her mouth to show him that his come was gone. Rick was wide-eyed and his own mouth was hanging open.

"Mandy, what has gotten into you?" Rick finally asked.

Mandy laid down beside her brother and pressed her body against his. "I was really, really, really horny. I've been hoping for about a week that you'd want to have sex, but you never said anything, so I decided to take matters into my own hands." While she spoke, Mandy lightly ran her fingers up and down Rick's chest. "Hey, take off your shirt, okay?"

Rick sat up and pulled off his shirt, then said, "I thought you didn't like having sex with me, Mandy. You never acted like you enjoyed it before…"

"You're silly, Rick," Mandy teased. "Of course I pretended I didn't like it! I was afraid you'd stop if you didn't think you were 'punishing' me!"

"You mean, all this time, any time I wanted to…"

"You just had to ask." Mandy leaned in and kissed her brother's cheek. "Of course, I probably would have kept pretending not to like it. You know, to let you think I was only doing it to get out of a spanking from Mom and Dad."

"Speaking of that, don't think this gets you out of a spanking for trying to come in my room without knocking. I'm still gonna spank you for that, you know."

This was what Mandy was waiting for. She immediately put on a contrite expression. "Oh, yeah. I'm sorry about that. Um, are you gonna spank me hard?"

"Heh. Well, it wasn't that big a deal, so I'll just spank you with my hand. Okay?"

"How many?" Mandy asked. She hoped it was a lot.

"I'll just spank you until I decide you've learned your lesson. Not too many, I guess."

Mandy decided to be bold. "You can spank me a lot if you want," she said very softly. She lowered her eyes and didn't look at her brother.

Rick was quiet for a moment, then said, "Okay, Mandy, now I reallywant to know what's going on. Spill it."

"Um, well…" Mandy thought for a moment and then said, "Remember a while ago when you said you think I like getting spanked?"

"I was just joking, Mandy," Rick replied.

"I know, but… I think you were right. I think I do like it." Mandy felt heat in her face, and knew she was blushing. "Maybe I get in trouble all the time on purpose. I mean, not on purpose, but…"

"I think I know what you mean," Rick said, grinning. "Well, from now on, I'll spank you whenever you want. You probably already know I like givingspankings."

"Yeah, I kinda thought you did. But I wasn't sure if it was just because you got to see me naked when you spanked me, or … if you really liked spanking me."

Rick laughed and said, "I like spanking you, and I like seeing you naked, and I like having sex with you… hell, Mandy, you're the hottest girl I know!"

"Really?"

"Every guy at my school wants to fuck you, Mandy."

Mandy giggled and said, "But every guy doesn't want to fuck his own sister!" She rolled her eyes and tossed her hair and continued, "Besides, I think I already have fucked every guy at your school! Oh god, I'm such a slut!"

Laughing, Rick assured his sister, "Oh, you haven't even come close to getting with all of them, Mandy. I would have heard about it if you had. Now, there are a few guys who claimthat they've had you, besides the ones I already know about, but I think they're full of shit."

"Okay, yeah, I guess I've only slept with ten different guys. That's like a different guy every month since I lost my cherry to Billy." Mandy looked up at Rick and said, "Anyway, weren't you about to spank me?"

"Yes, I think I was." Rick scooted to the edge of the bed and said, "All right, get yourself over my lap!"

Mandy tried to look reluctant, but in fact she was eager. Over Rick's lap she went. Rick started spanking her almost immediately, on her skirt. The skirt wasn't much protection, though, and the sting came through loud and clear. Mandy endured it mostly in silence, only offering an occasional grunt or yelp. She was waiting for Rick to notice her thong, but she could feel that her skirt wasn't riding up enough for him to see it. That surprised her, because as short as the skirt was, she thought it would ride up as soon as she bent over his lap.

Rick took a few minutes to deliver two hundred sharp spanks to the back of Mandy's skirt, then asked her, "Are you ready to get it on your bare ass?"

"Yeah, spank my bare butt, Rick…" Mandy said softly. "Teach me a lesson!"

"Then let's get your skirt up and your panties down…" Rick tugged Mandy's skirt up to her waist and exclaimed, "A thong!"

"Do you like it, Rick?"

"Oh yeah! It looks sexy, Mandy. You have a really great ass, so you look good in a thong."

"Really? Thanks!"

"It makes it easy to spank your bare butt, too," Rick chuckled as he administered a hard smack to Mandy's right cheek. He watched the way her already-pink flesh turned white for an instant where his hand smacked against her bottom. He spanked and spanked and spanked, and before long the pink darkened to red. Mandy's entire bottom was hot and she was starting to squirm. The bare-bottom hand spanking went on for a long time, though Rick didn't spank steadily. He paused frequently to squeeze and massage his sister's ass, rubbing away some of the pain and then creating new pain with another flurry of spanks. From time to time he spanked very slowly, letting several seconds go by between smacks.

More than once during the hand spanking, Rick paused and slipped his hand between Mandy's legs. Rubbing her pussy through the thin fabric of her thong, he would say, "Tell me again why I'm spanking you."

"You're spanking me because I tried to come in your room without knocking first," Mandy would moan. Rick's fingers were really turning her on. She knew her pussy was wet, and that Rick could feel it soaking her panties.

"That's right. And how long has knocking first been a rule?"

"Years and… ooooh… years…"

"That's right!" Rick would answer, and lay into Mandy's butt with a rapid series of very hard spanks. Mandy's rear end was positively glowing from the spanking.

The hand spanking finally ended with the three-hundreth spank to Mandy's bare bottom, more because Rick's hand was really starting to sting than because he thought Mandy had been punished sufficiently. "All right, Mandy, have you learned your lesson? Will you remember to knock from now on?"

I… I promise, Rick. I'll always knock from now on!"

Rick allowed Mandy to stand up, and her hands flew to her sore bottom. When Rick asked how her bottom felt, she replied, "It's hot, and it hurts!" But the spanking hadn't been severe enough to make her cry, and she secretly wished it wasn't over yet. Glancing down, she saw that Rick hadn't yet regained his erection. She was about to say something to encourage him to spank her some more, but he saved her the trouble.

"Now, Mandy, let's talk some more about that thong you're wearing," Rick said sternly.

"Wh-what about it?"

"I remember you, when you were thirteen, trying to talk Mom and Dad into letting you wear thongs. I also remember that they told you 'no'. They said that, when you turned sixteen, you could wear thongs, but until then you'd have to be satisfied with regular panties. Do you remember that?"

"Um, yes…" Mandy was staring at her toes.

"Good. Now, you know good and well that fifteen and a half is not sixteen," Rick said. "So, you are breaking Mom and Dad's rule right this minute. I'll have to punish you for that. Now tell me something else. Did you buy that thong special for today?"

"N-no."

"I didn't think so. How long have you had it?

"Couple months."

"I see. So I assume that you've worn it out of the house from time to time?" Rick was looking very serious now.

"Yeah. Sometimes."

"Then I'll have to punish you for that, too. One more question: Have you ever worn it out of the house under a short skirt?"

"Yeeeeessss!" Mandy groaned.

"Then I think you know that means even more spanking. I don't think Mom and Dad would allow that, even if you were sixteen. So," Rick smiled at his little sister's obvious nervousness, then continued, "since you've broken Mom and Dad's rule, I'll spank you like they would. Take off your skirt and T-shirt." A moment later, Mandy was stripped down to her thong and bra.

"Now," Rick directed, "go downstairs and get Dad's paddle — the big one — and bring it back here."

"Um, Rick? Dad would spank me downstairs."

"Oh, you're right. To do this right, I'll go downstairs and sit in his chair. You come down a minute later. I'll be waiting for you." With that, Rick left his room and went downstairs. In the living room, he made sure the curtains were shut and then took a seat in his father's recliner. He tried to sit like his dad would. Of course, his dad wouldn't be naked…

One minute later, Mandy came timidly down the stairs and stood in front of her brother. "I've been a bad girl, Rick. I deserve a good spanking. Please paddle my bottom," she said, using the words reserved for spankings from her parents and sometimes from Rick when it was a full-family punishment. Sometimes she was punished in her bra and panties, when her misbehaviour warranted more than a pants-down spanking but less than a naked spanking. Thinking about it, Dad would probably order a naked spanking for the offense for which she was now going to be spanked. Rick was letting her off easy.

"Fetch the… small paddle, Mandy," Rick said.

Mandy turned and walked to the coat closet where the spanking implements were kept. Although she knew that for today at least, she and Rick were playing a little game, she still felt the familiar butterflies in her stomach as she approached the closet. As she took the paddle from its place, she wondered if those butterflies were a physical manifestation of the inexplicable attraction she felt toward doing things to earn spankings. Her typical misbehavior was almost unintentional; she didn't mean to be disobedient. It was almost like something compelled her to break the rules and earn frequent punishment. Was the fluttering in her stomach signifying the strange excitement she felt before every spanking? Mandy wished she knew.

Rick took the offered paddle from his sister's hand, and patted his thigh. Mandy, compliant, draped herself across his lap without protest. "Punish my naughty bottom, Rick," she whispered.

"This part of your paddling is for simply owning and wearing this thong, Mandy." Rick raised the paddle and slammed it against Mandy's right butt cheek. He delivered a second blow to her left buttock, and then the third to the right side again. Because he didn't want to leave serious marks on his sister, he only gave her ten spanks with the small paddle, five to each cheek. They were solid spanks, though, and Rick spaced them so that each buttock was well covered.

It's strange,Mandy thought, but right now I feel like I'm really being spanked by Daddy…She was about to ask Rick why he had only spanked her ten times, but then she realized that he was trying not to mark her.

"All right, Mandy, get up and put this paddle away, and bring me the large paddle," Rick said. He watched Mandy wiggle across the room again, and admired his handiwork. Maybe, if I'm lucky, he thought to himself, Mandy will start behaving better and get spanked less my Mom and Dad. Then I can spank her more often without worrying about them seeing any marks I leave.Mandy handed him the large paddle and went back over his knees.

The large paddle was about five inches wide, and fourteen inches long, not counting the handle. It was long enough to cover both of Mandy's butt cheeks with each blow. Rick let the paddle rest on Mandy's bottom for a moment so that she could feel its weight. He could feel her trembling in anticipation. He brought the paddle up and swung it down across the meaty center of his sister's butt. Mandy had been relatively quiet throughout her spankings so far, but now she let out a little yelp. Rick's second blow slammed into Mandy's sit spot, and the third just below her tailbone.

A second round of three spanks landed on exactly the same spots, and Mandy was crying out her pain with each blow. She hollered especially loud at the spanks to her sit spot; she felt the impact of those smacks in her pussy lips! Four more spanks came, these overlapping the spots hit by the first six blows.

"Please, Daddy," Mandy sobbed, "I've had enough!"

"Oh, you haven't had quite enough, young lady," Rick replied. "There's still the matter of your wearing a thong out of the house, under a short skirt! Stand up!" Pointing to the ottoman in the middle of the room, he said, "I think you know the position." Indeed, Mandy knew the position. She stepped to the ottoman and bent at the waist, placing her hands flat on top of the footstool and then placing her feet about a yard apart. Rick stood to one side and slightly behind his sister.

The paddle smashed the paddle against Mandy's red ass, hard enough to make her squeal in pain. "Oooooooooooow! That one really hurt, Rick!" She rocked forward and back, trying to drive out the pain.

"Good." Rick hauled back and slammed Mandy's butt with the paddle again and again, until the count reached ten. He paused between each blow to allow her to return to the proper position before delivering the next blow. When he finished, he allowed Mandy to stand and rub her bottom. "Here, put the paddle away." He handed the paddle back to his sister and watched her walk gingerly across the room to return it to its place.

When Mandy walked back to her brother she glanced at his penis and was encouraged to see that it was showing signs of life. But not enough. Fortunately, Rick was on a roll, and had more 'fun' in mind.

"You know, Mandy, while I was paddling you I started thinking," Rick said, folding his arm across his chest.

"About what?"

"Let's go back upstairs first," Rick replied. He let Mandy lead the way so that he could follow and look at her butt.

Once the siblings were in Rick's bedroom again, Rick said to Mandy, "I was wondering about what you did when we had sex before I spanked you. You seem to have learned some new tricks!"

Mandy giggled. "Yeah, I guess I have! Did you like them?"

"Oh yeah! You were great! But… every time we've fucked before, we always just did it in the missionary position — you know, you on your back and me between your legs. We've never done it with you on top before. And I know that you've always done other guys in their cars, and it's hard to do any different position in a car. At least that's what I've found out when I've done it in a car. Besides, those guys always tell me what they do with you."

"Most guys would be afraid to tell another guy what they did with his sister," Mandy pointed out with a grin.

Rick laughed at that and replied, "Yeah, but these guys are all my good friends. And except for Billy, the first guy you did, I fixed all of them up with you because they wanted to have sex with you. I knew what was going to happen, and they knew that."

"Yeah, and you knew I wanted to sleep with them, too."

"Right. I wouldn't fix you up with one of my friends unless you wanted me to," Rick said. "But we're getting off the subject. Not only did we do it with you on top this time, but you also let me come in your mouth, and you swallowed. I've never heard of you swallowing before."

"Um, so what's your point?" Mandy answered, knowing exactly where this conversation was going.

"I want to know how you learned those things," Rick said.

In answer, Mandy glanced down at her brother's footlocker, then back at him.

Astonished, Rick said, "You've been watching my videos?" When Mandy nodded, he continued, "That means you've been coming in my room when I'm gone! Coming in my room and getting into my stuff!"

Blushing, Mandy admitted that Rick was right. She knew it meant another spanking, but she was willing to take it because Rick's cock still wasn't all the way hard.

"All right, I'm afraid I'm going to have to spank you again, Mandy. Even though you learned some good stuff from watching my videos, you should have asked first." He opened a dresser drawer and took out his belt. Then he pulled out his desk chair. "Bend over the back of the chair and hold onto the seat."

Mandy quickly got into position. The back of the chair was high enough that she had to keep her legs together and almost stand on her tiptoes. It was a perfect position in which to receive a belt whipping. She waited nervously.

Rick stepped behind his sister and tugged her thong down her legs. "Let's get this out of the way," he said. Mandy stepped out of the tiny undergarment, and was now left wearing only her bra. Rick knew she would feel vulnerable in this position, with her pussy clearly visible. He folded his belt in half and said, "This is for coming into my room when I'm not here."

The belt slashed across Mandy's already-burning ass, and she squealed at the sting. Rick whipped her hard and fast, and Mandy's legs were soon dancing and her butt was wiggling back and forth in an instinctive attempt to avoid the belt. She hadn't cried during her previous spankings, but she did now. Tears poured from her eyes and her makeup streaked her face. Rick wasn't whipping her nearly as hard as her father usually did, but it still hurt. The worst pain was mostly due to the fact that her bottom already hurt before the whipping started. Had she not been spanked immediately before the whipping, it wouldn't have hurt nearly as bad.

Mandy also realized that she hadn't expected her forays into Rick's room to be found out, and that now she felt honestly bad about it. Because she felt guilty, she welcomed the punishment she was now enduring. She forced herself to hold her bottom still so that Rick could whip her properly. She let herself drift into the familiar release of guilt that came with punishment. When she reached that point, the pain turned to pleasure.

Rick only whipped Mandy thirty times. When he had dealt the final stroke, he said, "I'd better stop. If I keep spanking you, you'll have lasting marks. Your ass probably shouldn't be showing marks, just in case you get in trouble with Mom and Dad in the next few days."

Still bent over, Mandy said, "Thank you for punishing me, Rick. I deserved it."

Rick stepped close behind Mandy when she stood back up. He made her gasp when he pressed against her sore bottom. Reaching around her, he took her breasts in his hands and squeezed gently. Pulling her against him, he said, "However, the belt was only for coming into my room when I was gone. You still need to be punished for getting into my things, which is a serious matter. And since I shouldn't punish your ass anymore…" He fingered the clasp between Mandy's breasts and popped her out of her bra.

"… I think I know how to finish your punishment."

Mandy nearly orgasmed when she realized that Rick was going to whip her tits again! And yet, she was afraid. It had hurt incredibly the last time, and Mandy's mind rebelled at the idea of enduring that pain again. But something inside her wanted it more than anything right at that moment. The part of her that was afraid won out first. Turning to face Rick, she fell to her knees and begged, "No, please, Rick! Not that again! Please don't!" But her face was near her brother's half-erect penis, and she noticed that, when she started begging, it stirred and began to stiffen more. In response, Mandy begged more pitifully. "Please, Rick, please! Anything but that!"

Rick realized that he was aroused by Mandy's pleading, but he held firm. "It's no use, Mandy. I'm going to whip your tits. You deserve it. Stand up!" He pulled her to her feet and walked her to his bed. "On your back, just like last time!" He pushed her down onto the bed and made her roll onto her back. "Now, I'm going to whip them more than last time. Will you keep your hands out of the way?"

Protecting her breasts with her hands, Mandy begged her brother, "No, no, no…. please don't!" When she saw that Rick's cock was now fully erect, Mandy desperately wanted it inside her. But she knew she'd have to endure a tit-whipping before Rick would fuck her. She could tell he was determined to punish her tender little breasts, and she realized that her nipples were hardening in anticipation. "I won't be able to keep my hands away, Rick!"

"Then I'll have to tie you up."

Mandy couldn't believe it. Her pussy was getting wetter just thinking about being tied up. She had never even thought about being tied up before, but the mere suggestion turned her on beyond belief. She held her wrists out to her brother.

Rick just looked at her for a few seconds, then he went to his closet and came back with a necktie. "This is all I have to tie you with." He knotted one end of the tie around Mandy's left wrist, then told her to reach over her head. He looped the necktie around a bar of his brass headboard, then tied the other end to her right wrist.

Finally, Rick wrapped his belt around his hand, leaving a length loose, and straddled Mandy's waist. Mandy looked into his eyes and whispered, "Make it hurt, Rick…"

The belt flashed down and slapped Mandy's left nipple. Mandy shrieked in agony and braced herself for the next lash. The next lash came quickly, smacking against her other nipple. Rick worked quickly, whipping back and forth from one breast to the other with a steady rhythm. Mandy was suffering intense pain and was straining against the bonds that held her wrists. A flood of tears wet her face and she wept loudly. "Oh god, that hurts so bad!" she wailed.

"It's supposed to hurt, Mandy!" Rick said with a grin. He paused after he had dealt five lashes to each tit and reached down to pinch and twist his sister's rock-hard nipples. Pressing his palms against her small breasts, he roughly squeezed them, coaxing more squeals from Mandy.

"Aaaaiiiiii! Ooooowiiiiee! Hurts…!" Mandy's chest was heaving with her sobs.

Rick let go of her tits and started whipping them again. He resumed his left-right-left-right pattern, this time lashing each small globe ten times before stopping to pinch and squeeze them. Mandy struggled fiercely under him, and wailed in pain, but he didn't relent. He torturously fondled her breasts even longer this time, taking pleasure in her miserable cries.

When he was finished squeezing and pinching, he climbed off of Mandy. "You're halfway there," he said. "I'm going to whip your tits thirty more times. But I'm going to do one at a time now, fifteen in a row to each tit."

Mandy's eyes were wide, but not because of Rick's words. Her eyes were locked on his cock, which was now, at last, fully erect. And Mandy wasn't sure, but it looked even bigger than normal. She couldn't wait for him to stick it in her. But for now, she had thirty more lashes to endure.

Rick delivered those lashes even harder than the first thirty. Fifteen quick, hard strokes to Mandy's left breast had her writhing and squealing in pain, and fifteen more to her right breast had her screaming. He dealt the final stroke, then dropped the belt and stared at his sister's abused tits. He was breathing as heavily as she was.

Quickly getting her sobs under control, Mandy looked at Rick and said, "Fuck me! Fuck me Rick! I need your cock! Fuck me and make me come!" To emphasize her plea, she spread her legs and raised them into the air. "Fuck me!"

Rick needed no further encouragement. He got on top of her, then drove his throbbing cock into his sister's tight, dripping wet pussy. He buried himself to the hilt, then pulled back and drove in again. A rhythm was quickly established, and Rick started fucking his sister harder than ever before. To his own surprise, he wanted to make her come, to reward her for the way she had so completely given herself to him tonight. In his porn videos, the girls always climaxed when the guys fucked them, and he was determined to get the same reaction from Mandy. Thinking about it, Rick realized he had never made a girl come. Tabitha, one of the girls he slept with now and then, acted like she was having an orgasm every time, but he was pretty sure she was faking. He wanted to give Mandy a real orgasm.

And he did. He had only been pounding her pussy for a minute when her eyes rolled back in her head and she let out a wail of pleasure. "Oooooooooooooooh! Yeeeeeeeeeees! Yes! Oh god, I'm coming, Rick!" It was the first time she had ever been fucked to orgasm. Mandy wrapped her legs around her brother and pulled him deeper into herself, and a moment later she orgasmed a second time. Her moans and cries of ecstasy filled the room.

"You like that, don't you?" Rick grunted while he continued stroking in and out of her tight, wet pussy. "I'll bet you like this, too!" He reached down and pressed his thumb against Mandy's clitoris, rubbing it in little circles. The combination of clitoral stimulation and the steady thrusting of his cock made Mandy come again, almost instantly. Mandy's whole body convulsed, and Rick could feel her pussy clamp tighter around his cock.

Thinking of his porn videos, and knowing Mandy had watched them too, Rick had an idea. He pulled out of his sister's cunt, prompting a protest from her. He reached up and untied her wrists and said, "Turn over. Get on your hands and knees."

Changing position, Mandy asked, "Doggy style?"

"Uh-huh." After making some slight adjustments to Mandy's position, Rick was inside of her once more. He quickly discovered that, in this position, he was able to thrust even deeper, and he took full advantage of that. Mandy was moaning with pleasure, feeling her brother in places she'd never been touched before.

Now it was Mandy's turn to remember things she'd seen in the videos. "Slap my butt!" she cried. She felt the smack, and the pain combined with the pleasure she was feeling. On top of everything else, her tits were throbbing. A few more slaps pushed her over the edge, and she climaxed one more time.

Neither of them could believe how long Rick was lasting, but neither brother nor sister was complaining. Mandy had already come four times, and felt like she was going to come again. Sure enough, another orgasm rocked her body a minute later.

Finally, Rick could hold back no more. "Oh shit, Mandy, I'm coming now!" He pulled out of his sister's pussy, and Mandy quickly turned around. She was in time to get her mouth on his cock before the first blast, and she eagerly sucked down every last drop of his sweet juices.

Exhausted, the two siblings collapsed into each other's arms. They lay there with their naked, sweating bodies pressed together. They both knew that it had been the best sex either of them had ever had. They held each other in silence for a long time, hearts pounding.

Mandy finally spoke. "Thank you, Rick."

"For what?"

"For making me come. No guy ever did that before. Not even you, until now."

"I guess I've never really thought about it, you know? I guess most of us guys just want to get off quick. I didn't realize how good it could be if it lasted longer."

Mandy giggled and said, "So my plan worked."

"What plan?"

"Well, I saw some of the guys in those movies fuck a girl, and then fuck her again, or fuck a different girl, after they took a break," Mandy explained. "And I noticed that they always lasted longer the second time."

Chuckling, Rick said, "They last a long time the first time, too!"

"Probably cuz they get a lot of practice," Mandy laughed. "But anyway, I decided to fuck you, and then make you spank me after. I was hoping you would get hard again so you could do it again." She rubbed her sore bottom and said, grinning, "It just took a little longer than I planned on!"

Rick hugged his sister and said, "You know, Mom and Dad won't be back until tomorrow night."

Mandy's face lit up and said, "Yeah! So we've got all night, and most of the day tomorrow…"

"We've got time to try all sorts of things…"

"I wanna try some of the other positions I saw in those videos," Mandy said. And maybe I can persuade you to eat my pussy, she thought to herself. Then she thought of something else. "Hey, I was wondering something."

"What?"

"Where'd you get the idea to spank my boobs? I didn't see that in any of your movies."

"Oh. Um, well, there's a friend of mine who's in college, and he has some

S&M videos."

"S&M?" Mandy asked, puzzled.

"S&M is about masters and slaves, and all different kinds of punishment, besides spanking. I guess you'd have to see the videos yourself. I can't really explain it, because it's not just about sex and pain. There's a whole psychological aspect to it. Jarrod could explain it better, cuz he's into that whole scene."

"Can I meet him?"

"I dunno. He might not go for it."

"Why not? I'm willing to try it out. I think."

"Well, because you're only fifteen. You're jailbait. He might be afraid of

getting arrested."

"Oh. I wouldn't tell anybody," Mandy promised.

"I'll talk to him and see what he says," Rick said. "Maybe he'll at least let

me borrow his videos, and I can let you see them."

"Okay," Mandy sighed. Looking down, she noticed that her brother was starting to get hard again. She smiled and reached for his dick…
