It was completely unexpected. My fiance was out of town on vacation. I would have gone with her, but due to a few emergencies at work I was unable to take my own vacation at the same time. So I was very happy to know that she would be home in two more days. Two weeks apart was just too long!

That being the case, I was naturally very surprised when I came home from work and heard the shower running. My fiance and I don't live together, but she has a key to my apartment. I was elated at the thought that she had come home early and was waiting to surprise me. So I decided to surprise her, too.

I closed the front door very quietly behind me and tiptoed down the hall to the bathroom. The bathroom door was open, so I crept right on in. I slowly reached for the shower curtain, then suddenly yanked it wide open.

"SURPRI…" My jaw dropped, and I immediately pulled the curtain closed again. I heard a giggle from behind the shower curtain, and heard the water shut off.

"Anna, what the hell do you think you're doing????" I shouted.

The shower curtain was yanked open again, and I was presented with a full frontal view of Anna's dripping wet nude body.

There was only one problem: Anna is not my fiance. She's Karen's younger sister.

"Hi Jimmy!" Anna said cheerfully, while she posed for me in a way that I'm sure she thought was provocative.

Let me tell you about Anna. She's about five feet, six inches tall, and blonde. At nineteen years old, her figure is slender and lithe. Her breasts are small and perky, her legs are long, and her ass round and firm. She sports bright blue eyes. And to be perfectly honest, she is prettier than Karen. Physically.

In every other way that matters, she doesn't even come close. Frankly, she's a bitch. She's been flirting with me since the day I met her, and more than once she's tried to seduce me. Karen knows about this, of course, and we both laugh about it, and fortunately she knows me well enough to trust me. Anna likes to wear short skirts and short shorts that leave half of her butt hanging out, and she's fond of strutting around in front of me in a microscopic thong bikini at every gathering of our group.

Anna is one of those women who thinks she can get by on her looks. She also thinks that all men are the same. That means she believes that we all think with our dicks. So she's constantly using sex to get what she wants. Apparently that usually works for her, as evidenced by her expensive wardrobe, jewelry and car that she obviously can't afford on the money she makes as a waitress.

Too bad for her that I'm too much in love with her sister to fall for her wiles.

"Anna, please explain what you think you're doing," I said to her, taking my eyes off her nakedness and looking her straight in the face. "And how did you get in here?"

"Karen left her key behind in our apartment when she left," Anna said, smiling impishly, "and I think you know why I'm here." She stepped out of the shower, and though I jumped back she was too quick and she managed to get her arms around me. Pressing her naked body against me she continued, "I want you to fuck my brains out and make me scream! I know you want to." She emphasized that last remark by reaching down and grabbing my package, which was erect in spite of my lack of interest in Anna. "You can have your way with me!" She tried to kiss me, but I pulled away.

I managed to extricate myself from the unwanted embrace. Then I made a point of slowly looking her up and down. I gazed at her breasts, then let my eyes wander down to view her neatly trimmed pussy. I twirled my finger to indicate that I wanted her to turn around Then I took a moment to study her ass, which still had water beaded on it.

"I can have my way with you?" I asked conspiratorially when she turned to face me again.

"Yes!" she said, attempting to hug me again. I stopped her with a hand on her shoulder.

"Anything I want to do?" I said, doing my best to look like I was really interested in her offer.

Convinced of my sincerity, Anna licked her lips seductively and said, breathily, "Anything."

"And you want me to make you scream, huh?" I reached down and took both of her hands in mine as I looked into her eyes.

"Oh god, yes!" Anna cried out.

I grinned and said, "You got it!"

Completely without warning, I sat straight down on the lid of the toilet seat and hauled Anna face down across my lap. Anna was too surprised to resist, but she gasped, "What are you doing?"

"I'm going to make you scream, just like you wanted, Anna."

"But…but…"

"And a nice butt it is, Anna. It will be even nicer, I think, when it's been painted red!"

I laid into Anna's ass with my bare hand. My palm made an incredibly loud SPLAT! as it connected with her still wet flesh. I knew that had to sting, and Anna's shriek of pain confirmed it.

"Goddamn it, Jimmy!" she shouted. "That fuckin' hurt!"

"Of course it hurt!" I laughed. "You said you wanted me to make you scream."

"That's not what I fuckin' meant!"

"Well, it's what I meant. And you did say I could have my way with you, and do anything I wanted." With those words, I started spanking her in earnest. Hard. I'd had quite enough of her antics, and this little scenario was the final straw. Over and over and over, my hand smacked against her cute little ass. I took care to cover her whole butt with my hand.

"Stop it! Jimmy, stop it! Please? It really hurts!"

"Oh no, little girl, I'm afraid you've had this coming for a very long time! You know damn well how much I love your sister, and I'm sick and tired of your little games!" I reinforced my words by spanking her even harder. I was worried that her kicking legs were going to cause her to fall off my lap. I shifted her to the left so that her butt was over my left thigh, then moved my right leg to clamp hers between mine. No escape now! I also had to hold her wrists with my left hand, as she kept trying to reach back to protect her butt.

"Fuck you! Asshole!" Anna screamed at me.

"You know, Anna, if you keep using that kind of language with me, I'm just going to have to spank you longer!"

"Fu… no, please, stop Jimmy! Stop! I'm sorry! I won't bother you any more! I'm sorry!!"

Oh, she certainly was going to be sorry! I intended to make sure of that. I started spanking her faster. By this point, I'd been spanking her for several minutes, and her ass was starting to glow with a nice shade of deep pink. It was also getting quite warm, and I planned to make it even warmer. I was determined that Anna was going to learn a lesson.

Anna's struggling and shouting died down a bit after a while once she realized it wasn't going to do her any good. I could tell she was crying, though, by the way her body was shuddering. Good. Maybe this was getting through to her. I kept spanking her hard, even though by now my hand was really starting to sting, too.

As it turned out, Anna's becalmed state was a ruse. It seems she thought that if she acted compliant, I might stop spanking her. When it became apparent that I wasn't stopping, her churlishness returned.

"You'd better stop it, Jimmy, or I'm going to tell Karen everything!" she bawled.

I paused, and let my hand rest on her now very hot bottom. "You'll tell Karen?" I asked.

"Yeah. She's gonna find out everything!"

"Well…" I replied slowly, "in that case, I guess I'd better make it worth the trouble, eh?"

"What? What do you…"

Without answering, I stood her up and turned her to face the bathtub, then pushed her to her knees. I made her bend over the edge of the tub, with her hands inside on the bottom. When I knelt down behind her, I saw her shift her body and open her legs! She must have still thought I was going to fuck her! Unbelieveable. I slid open the drawer next to the sink and picked up the object inside. Anna's delusion was about to come crashing down.

I picked up the wet washcloth from the edge of the tub and wrung it out over Anna's red bottom. She gasped at the touch of cool water. "Thank you…" she whispered, thinking I was cooling her bottom off.

Imagine her surprise when the big hairbrush in my hand slammed into her right buttock! She howled miserably, both with surprise and pain. The hairbrush left a dark red mark on her cheek. My arm went back again, and another solid blow struck her left cheek. Whack after whack after whack crashed into her burning ass. Her response was to yell and shriek, but it seemed she had enough sense to keep her hands out of the way of the hard wooden hairbrush.

I didn't count the spanks, but by the time I finally stopped Anna's ass was raspberry red. I put the hairbrush away and seated myself once more on the toilet seat lid. I left Anna where she was, and listened to her weep while she rubbed her well-spanked bottom with both hands. I gave her as long as she needed to compose herself. When her sobs subsided I said, "Get up, Anna."

Anna stood, then slowly turned to face me. Unusually for her, she didn't say anything, and she actually tried to cover her breasts and crotch. Staring at the floor, she waited for me to speak.

"Where are your clothes, Anna?"

"On your b-bed…"

"Then let's go get them. I want you to get dressed, and then I want you to go home." I stood up and allowed Anna to leave the bathroom first, then I followed her to my bedroom. I half suspected that she would try another pass at me, but instead she just reached for her clothes.

I watched Anna step into a pair of black thong panties, then put on a matching bra. Her designer blouse was next, and then she picked up her designer jeans. When she tried to get into the jeans, I felt a twinge of pity for her. Those jeans were skin tight. I had seen them on her before, and knew that they looked like they were painted on. Indeed, it was with much effort, delicate wiggling and many little yelps and gasps that she was finally able to get the jeans all the way up. Once she got them fastened, they were like a second skin. I knew that had to hurt!

Slipping her feet into a pair of sandals, she looked at me and said, softly, "I deserved that." Then she turned and left without another word. I watched her walk stiffly and almost bowlegged to her car, then closed my front door when I saw her drive away.

Anna never made good on her promise to tell Karen, and I decided it was best to keep mum too. Sure, Karen was well aware of the way Anna flirted with me, but Anna had never been so brazen before, and I wasn't sure how Karen would handle Anna's latest escapade. When Karen eventually noticed that Anna was no longer flirting with me, she chalked it up to her sister finally growing up.

Karen remained blissfully unaware until a couple months after our wedding. Then one day Anna came to visit us. She nervously told us of something really stupid she'd done. She confessed that she had gone to a casino, and had lost her rent money, and begged us to help her out of the mess before she lost her apartment.

Of course, Karen insisted on helping her out. Between us, Karen and I make enough money that it wouldn't be too much of a burden, so I agreed. And then Anna, in her gratitude, really threw me for a loop.

"Thank you!" she cried, clapping her hands. "I promise I'll pay you back!" But then she got serious, and started looking nervous again. "But, um…" She paused as if she couldn't decide what to say. Then she blurted out, "But I think I need to be taught a lesson." She looked at me and said, "A hard lesson."
