My Wife's Little Sister (2 page)

Her eyes locked with mine, and I could feel her start to lean in, as if to kiss me. I broke the gaze quickly, turning back to face the blank TV. I willed the TV to turn on, as if for one moment I could have the psychic powers necessary to break this sexual tension.

Kelsey seemed mad, but didn't give up even at this point. She grabbed my knee, moving her hand up. I thought she would stop, but she didn't. When her hand got to my cock, she grabbed it through my shorts.

I grabbed her hand. "This has gone far enough, Kelsey. If you leave now, I won't tell your sister about this."

Kelsey leaned in, whispering seductively in my ear. "You're right. Lynn never has to know about this."

A shudder rippled through my body, but I retained control. "We can't do this."

She continued to lean in, her lips now brushing my ear. I felt the hairspray in her hair brushing up against the back of my neck. "Why not?"

There were many reasons, but I went with the worst one. "Because it's not worth me going to jail over."

She giggled right in my ear, a soft little giggle that sent another wave of testosterone through my body. "You don't have to worry. I turned eighteen last Saturday." I swore to myself. Of course, now I remembered Lynn going to her parents house that day. I had stayed home out of habit. Lynn continued, "I'm an adult now..."

I laughed, the laugh sounding hollow even in my own ears. "You're definitely not acting like an adult. An adult wouldn't try to seduce their sister's husband. No, I'm afraid you're still a bratty teenager."

Kelsey squeezed my cock. She might not like being talked to this way, but it wasn't going to turn her off. "Oh really," she said. "And why do you think I haven't grown up yet?"

I should have dropped it right there, but I had so little blood left in my brain at this point. "I've seen the way your daddy spoils you. My guess is he's never disciplined you the way you need to be disciplined."

She leaned in and whispered in my ear the last thing needed to push me over the edge. She said it so seductively that there was no way I could have resisted. "
So discipline me.
"

Something inside me snapped. With my hand that was already on hers, I pulled. My other arm got up and out of the way as her tiny body was yanked across me. She squeaked with surprise, but I could tell that this was exactly what she had always wanted. Her tits rested on my leg as her legs swung up onto the couch.

I still had her hand pulled as far to my side as I could, and her ass was right underneath my raised hand. She was face down, bent over my knee, in perfect position. Without waiting for her to react, I brought my hand down hard on her ass. The sound of the spanking was muffled by the soft satin fabric, but by the gasp that Kelsey made, I could tell that the spanking was painful.

"You like teasing your brother-in-law?" I asked. She nodded quickly, and my hand came down swiftly on her satin-clad ass. She moaned, and as I rubbed the spot where I spanked through the soft fabric, I could feel my erection crying out in my pants for release. She began to grind her ass into my hand. The skin on her bare back looked so smooth, I wanted to run my fingers all over it. For now, however, the girl needed a lesson.

"Spank me again," she gasped, and I happily obliged her, bringing my hand down harder than I had before. She screamed, and I spanked her again. My hand rose up again, but she moved her free hand to her ass, feebly trying to stop me. She was gasping in my lap. I slowly brought my hand down to her tender ass, rubbing her gently.

"Have you learned your lesson? Are you going to stop teasing me, Kelsey?" I asked. I might still be able to get away from this, still might be able to send her out the door so that I could jerk off to this moment for the rest of eternity, my conscience intact.

She turned, and I let go of her hand so that she could look at me. I could see tears in her eyes, and she looked genuinely repentant for a moment. However, once she got a look at my face, once she could feel my hard-on underneath her, her face turned into a smile of defiance. "Never," she said.

I grabbed her hand and pulled her so that she was face down again. I grabbed the bottom of her sexy satin gown and pulled upwards. I could hear a few of the stitches pop, some fabric tearing, but I didn't care. I exposed her ass to me. A tiny black thong was all the underwear that she had on, and her ass cheeks were already rosy from the beating they had received, but there was no single hand print. The dress had softened the blows a little bit.

Not for long
, I thought. My hand came down swiftly, this time connecting with a loud SMACK. She had been mostly compliant until now, but suddenly she began to struggle. I didn't care; she had to be taught a lesson. My hand came down again, and this time she howled a little in pain. Her hand came down again to block me, but I spanked her other ass cheek, leaving a giant red hand print.

She cried out. "Stop, please!" I stopped for a moment, rubbing that last hand print gently. She relaxed as I rubbed. I touched her little thong, and she moaned a little bit. My fingers moved without my brain telling them to, rubbing along her little asshole, moving downwards. I was shocked when I touched her pussy. It was so wet that she would probably have a wet spot on the front of her dress. I rubbed her slightly, and heard her moan, "Yes..." It was the moan of a girl's wildest dream coming true.

"Is this what you wanted your prom date to do to you?" I asked, rubbing a little more vigorously.

"Oh, God, yes," she moaned back, writhing on my lap.

"I don't think he's going to get a chance now," I said. I brought my hand out of her underwear, letting go of her hand at the same time. I grabbed her panties and pulled, the waistband breaking instantly.

Instead of protesting, Kelsey moaned and thrust her ass out even more. I didn't want her to get too comfortable, so I gave her ass one last spank, the hardest spank yet. With her hands free, she was able to flip on her back. I got out from under her, sitting on the edge of the couch as she lay across it. I saw the wet tears in her eyes, making her mascara run a little, but I also saw the wet sheen on her pussy, neatly shaven.

"Well, well," I said. "Looks like you went all out for the prom."

Her frown quickly turned into a sexy smile. "I got my hair and nails done for the prom, I figured I might as well get my pussy done too." She hiked her dress up even more, spreading her legs open a little more. I was immediately reminded of how shy Lynn had been the first time we had made love, of how I didn't actually see her pussy until the third time we had sex. Apparently Kelsey didn't have the same shyness.

All my inhibitions were out the window at this point. As she lay there, biting her lip and looking nervous, I knelt on the floor and lifted her feet by her heels, putting her legs on my shoulders. She gasped as my tongue licked up her leg, getting closer and closer to her pussy. She closed her eyes and moaned as I tasted her, lapping up her juices as they leaked from inside of her. She was so wet, so ready.

As another moan escaped her lips, I buried my face into her pussy. My tongue was on her clit, and her moans turned to gasps. Her hands gripped the couch's fabric as her legs tightened around my neck. I knew the pace and rhythm that her sister liked, and I figured it would work on her as well. Within moments, I was sure that I was correct, as her entire body began to buck and writhe on the couch.

Suddenly, she froze, her legs tightening even further around my neck. I would have had to stop if it was Lynn, but Kelsey's legs were thinner and not as strong. I continued to lick, knowing that she would cum soon.

She didn't disappoint me. Within a few moments, a stream of fluid began to flow from inside of her. I backed away and furiously rubbed her clit with my hand. The stream of fluid became a torrential downpour as my fingers touched her in just the right way. She had her eyes squeezed shut tightly as the fluid squirted from within her young body. As the leak slowed to just a dribble, she opened her eyes briefly. "Nobody's ever done this to me before. You're amazing," she gasped, before her eyes rolled back into her head. I continued to rub, and suddenly another rush of liquid poured out of her as her body seized with pleasure.

Just like her big sister
, I thought. I stopped rubbing and her own hand went to her clit immediately, softly rubbing herself as she writhed in ecstasy. I took my shirt and pants off quickly, and when her eyes opened they went straight to my cock. She froze. "Oh my god," she said. "It's even bigger than I thought it would be."

I smiled, but wasted no time. I thrust my cock into her face, and she looked at me with apprehension. "I've never-"

I didn't wait for the whole sentence, instead thrusting it into her mouth. She moaned, and was soon sucking with all her might. The way she moaned while sucking, I would think she was eating the most delicious food of her life.
Well
, I thought,
my cock had been the one thing she had desired for years now.

I pulled the top of her satin dress down. She hadn't been able to wear a bra with this dress with her back being exposed, and so her boobs spilled out easily. I grabbed one, enjoying the feeling of this teenage tit. They were bigger than they had been years ago in the hot tub, definitely a C-cup or maybe even a D-cup at this point. The nipples were barely lighter than her skin, and I tugged at one of them mercilessly as she took my cock in her mouth, deeper and deeper.

Suddenly I grabbed her hair and pulled her up, mussing up her perfectly styled hair in the process. I began to thrust deep, fucking her mouth with all the force I could muster. My cock went deep in her throat, making her gag. More tears sprang from her eyes, ruining her makeup even further.

"Do you like this?" I asked as I pulled my cock out of her mouth. She nodded, obviously in rapture. "Tell me how bad you want it."

"I want it," she croaked out, obviously with a sore throat from the abuse I had just given her.

I slapped her in the face with my cock. "That's not good enough. Tell me you want me to fuck your mouth."

She seemed to blush, but she quietly said "I want you to fuck my mouth."

I grabbed her cheeks. "What was that? I couldn't hear you."

"Fuck my mouth, please!" she said loudly.

I let go of her cheeks and thrust my cock back in her mouth, fucking her as she had asked. Soon, she had her hands on my hips, pushing me away. Okay, I thought. She had had enough.

I got on top of her on the couch, and she gasped. "Please, be gentle. I..." she trailed off.

"You what?" I asked.

"I- I had always hoped- I've been saving myself..." she said, trailing off.

I realized what she was trying to say. "You're a virgin," I said.

She blushed again, then nodded slowly. "Please, I want this so bad, but be gentle..." She bit her lip.

I paused for a moment. Lynn hadn't been a virgin when we had met, and here I was, about to deflower her sister. My conscience almost won out, but my throbbing member was now the throbbiest it had ever been. It was in control, and it wouldn't let me stop.

I pushed so that the head of my cock was just entering her flower, spreading her just a little bit. She closed her eyes, obviously scared. I leaned down and kissed her, the first kiss I had given her since we had started this. I felt her whole body relax as she deeply kissed me, her tongue going into my mouth. I tasted my own pre-cum as she no doubt tasted her own wet pussy, but I was way too turned on to be grossed out.

Her body yielded to me, and her legs spread open further. Her already wet pussy got even wetter, and I pressed into her. She wrapped her hands around my neck, holding me tighter for comfort, and I let her. I could feel her satin gown underneath me as I began to rock back and forth, slowly spreading her open underneath me.

I pressed in, and within an inch I encountered resistance. She hissed in pain as I rocked back and forth, rubbing up against her hymen over and over. Finally I pressed in deeper, tearing through the resistance. Her nails dug into my back as she gasped through the pain, and she tensed up. I kissed her again, and she kissed me hungrily, desperately. As the extra lubrication from her hymen flowed through her, she loosened up again, and my cock slid all the way inside of her.

As I began to slowly thrust inside of her, I braced myself for the inevitable poke from the IUD that I had become conditioned to. As I buried myself to the hilt again and again, no poke came. I smiled. Of course Kelsey didn't have an IUD, she wasn't sexually active.
Before today
, I mentally added.

Soon she was completely relaxed, and she wrapped her legs around me. I began to rail into her, thrusting into her with all of my energy. Her squeaks of pleasure soon became cries of desperation as she tried to pull me even deeper inside of her. I heard her high heels clack together repeatedly behind me as her legs were tossed back and forth with the sheer energy of my fucking.

"Yes," she moaned. "Yes, Tom, fuck me. Oh, God, please fuck me!" I honestly couldn't tell if she was crying out in ecstasy or if "God" and "Tom" were interchangeable terms to her. Her eyes rolled back into her head again, and I could feel her pussy begin to tighten underneath me. I knew what this meant, and continued to go deep inside her.

Her back began to arch and she dug her high heels into my back as she came, her pussy's contractions squeezing me harder than Lynn's ever had. This fresh, teenage pussy was tighter than I had experienced in years. I couldn't help myself as I began to thrust deep inside of her.

As her orgasm finished, I pulled out of her, standing up. Her pussy was leaking juices onto her dress, which was bunched up and wrinkled now. I had sweat a little bit and the front of it probably smelled like it. There would be no covering that up with fruity perfume.

Her hands were on her tits as she continued to writhe. Her eyes opened and looked at me, a crazy, animal lust within them. She got to her feet, and immediately noticed how messed up her dress was. She quickly shimmied it off her hips, letting it hit the floor.
