The story of how it came to be that I fucked my 14-year-old sister-in-law could be told in many more words than this piece here, but the truth is that it all boils down to a couple of nights.

Obviously in the nearly two years after I first married one of Stacy's older sisters, a lot happened that led to the sex, but there was nothing really that could be written to hold the readers interest.

From the first day that I was introduced to Stacy I was taken with her. I guess that being 22, fairly attractive, in good shape, and just out of college made me attractive to her as she ended up with a monster crush on me that really opened the door to the rest of this story. The tale between us started out with the customary stares and giggles from Stacy when she was only twelve. Everyone knew that Stacy had a crush on me, though we all just dismissed it as youthful infatuation and I always played the responsible, collected, don't encourage it, not affected by it husband.

My wife and I tried to get out at least once a month, to do dinner and a movie. For the first six months after our son was born, we didn't get out. When we decided to resume our 'date nights', we picked my sister-in-law Stacy to baby-sit little Cletus, even though she wasn't even 13 at the time. We just figured that she was responsible enough, and if my mother-in-law was needed, she was just a couple of blocks away.

It became a steady ritual on the third Saturday of every month for Martha and I to get out. Because most times we didn't get home until after twelve, it also became part of the norm that Stacy would always end up spending the night sleeping with my son in his bed.

On one of those Saturday 'date nights', shortly after our son turned two, my wife and I returned home earlier than usual. Stacy was still up, watching the TV in the living room. The baby was sleeping in his bed, which has sides to protect against falling out.

Martha invited her sister to watch the TV up in our bedroom with us and Stacy happily agreed. I think they both felt guilty because they didn't get together enough since our marriage.

Stacy came into our room in her robe, after Martha and I had readied ourselves for bed. In fact, we were already in bed with the TV on when my sister-in-law arrived. I don't know who decided or if it was just by happenstance, but I moved over toward the center of the bed to make room for the youngster. She innocently removed the robe to get into bed, and it took all of my willpower not to pay total attention as the youngster was wearing one of my own old t-shirts as a nightgown.

With the three of us lying on the bed with me in the middle watching this movie, it seemed as if it might be a talk-a-thon between the sisters with me in between, but my wife soon dosed off, leaving Stacy and I to finish watching the movie alone. As much as I was taken by the youngster's beauty, and knew that she had a crush on me, I would have never even considered saying or attempting anything with the youngster, being absolutely too terrified for fear of being executed by my wife's entire family. That doesn't mean that I wasn't fully aware that the young beauty was there. I sneaked peaks and allowed my nose to appreciate her presence.

With Martha now sound asleep, Stacy and I continued to quietly just watch the movie. After a while I got bored with the movie, being too aware of Stacy lying so close to me, wearing only panties and my old t-shirt. As my testosterone levels were obviously rising, I laid back and closed my eyes, trying to avoid seeing her, but being very conscious of her presence. Still I couldn't avoid thinking of her, which was what I did until I eventually dosed off.

Later that night I woke up lying on my side with my wife behind me and Stacy in front of me. She was sleeping about halfway down the bed with her back to me. Instead of turning right back to sleep I was once again aware of this young beauty, and I had one of those moments of inspiration. Pretending to be asleep, I innocently began moving my leg as though to get more comfortable and brought my foot up and placed the top of my foot squarely in the crack of my young sister-in-law's sweet little bubble butt. The feeling of my foot nestled between these 14-year-old cheeks, nestled where her thighs joined, ended up giving me an erection of steel.

Soon, Stacy stirred. In retrospect, I suppose it was the contact of something foreign in the soft indentation where her ass met her legs that woke her. Sensing that she might be awake, I simply continued to pretend to be innocently sleeping. The youngster lay there for a moment, not moving or doing anything, and then she actually pressed her ass back against my foot, and amazingly, began flexing her cheeks, almost like she was grabbing at my foot with her ass.

My cock, already hard, now almost hurt because it got so tight feeling. I couldn't believe what Stacy was doing. Then, even more surprising, she reached behind herself and gently pulled the back of the t-shirt up past my foot, so that all that remained between my foot and her ass was her panties. The warmth and firmness of her flesh was incredible.

My heart was beating wildly at what was happening. I was actually debating with myself whether to move my foot, but before I could get up the nerve to do so, Stacy moved again. This time she simply got up and left the room to go to sleep in my little son's bed.

I was so painfully hard that I had to get up and get off in the bathroom dreaming of fucking that incredible ass. I couldn't help but to later wonder if maybe Stacy had done the same, once she got to bed by herself.

In the morning, I didn't expect her to say anything and she didn't. Thankfully, she acted as though nothing had happened.

That seemingly nothing episode was the watershed event for me and although nothing more immediately happened, I began thinking of the youngster quite a lot. On her next two baby sitting stints, it was all that it could be to avoid letting Martha see me ogling her sister, but that doesn't mean that Stacy didn't notice. She did. I could see it in her eyes. Hell, she even blushed once when she caught me looking directly at her crotch.

It was almost three month after that night when Martha reminded me that she was going out with her older sister and their best friend that coming Friday, something that had been arranged months earlier to celebrate the friend's birthday.

I had been thinking and yes, plotting, so when she gave me this reminder, I gave a surprised, "Oh shit."

"What's the matter?"

"I told Pete Romano and Tommy Cuddahy I'd meet them after work and we'd have a night together."

"Damn Ray. You knew that I was going out. I've reminded you a couple of times."

"Yeah, yeah, I know, I know. I just forgot. Damn it!" I paused and then, ever the martyr, added, "No big deal. I'll cancel out with them."

Martha nodded and went on working on opening the mail. Then she suddenly said, "Why don't you just have Stace come over and watch Cletus?"


... I waited for affect, as if I hadn't thought of that and then said, "Do you think she would, on such short notice?"

"Awww, for her fav-wit brother in law?" my wife teased. "I don't know if she'd do it for me, but I'm sure if you called her..."

"Yeah, alright. Can I help it if I'm a hunk?" I teased back then asked, "Would you call her and ask her?"

"Yes. What time will you be home? Or should I tell her she should just count on sleeping in the baby's room?"

"Yeah more than likely," I said.

"I don't know if I should trust the two of you being alone without me," she said, laughingly. Then added, "I'll give her a call as soon as I'm done with this stuff. I just have to file a couple of bills."

Thus it came that Stacy came to baby sit Cletus on Friday. Martha stayed until my sister-in-law arrived and then left to go out with her other sister and their friend.

I had told my wife to tell Stacy not to expect me, as I probably wouldn't be home until after midnight.

All I did was stay a couple of hours later in work, catching up on some of the crap that I always put aside. After that, I stopped at a restaurant to eat, putting myself in a mellow mood by polishing off a bottle of Chianti.

I got home just around 9:30 PM. I thought I'd find Stacy either in my son's room or watching TV in the living room, but she surprised me. I called out to let her know that it was me and she responded, "I'm in here," from my bedroom.

I opened the door and looked in. Stacy had already put Cletus to sleep in his bed and was watching television on Martha and my bed with the lights off. From what I could make out she hadn't switched to her nightwear. She was still in her sweater and jeans.

"Hey, how are you?" I said.

"Is anything the matter?" she asked, concerned.

"No, everything's fine. Just didn't stay out like I thought we would. I was too tired," I told her, then said, "Don't get up ... you can watch whatever you're watching."

"You don't mind?" Perfect, I thought. Better than I could have planned.

"Nah. I don't know why I'm so tired, but you're not going to bother me watching that. I'll probably be asleep before I'm on the bed," I kidded.

As Stacy turned her attention back to the TV, I grabbed my pajama bottoms from the dresser and took them into the bathroom where I stripped and put on those bottoms, purposely not wearing any underwear beneath.

Coming back to the bedroom, I padded my way to the bed. Stacy's illuminated face looked at me as I then took up my usual spot in bed, which happened to be laying down, facing her.

"I'm gonna conk right out. Feel free watching whatever you want," I told her, then light heartedly added, "But you might not want to get too close to me, cause being so beautiful, I might mistake you for Martha ... I wouldn't want to be accountable for anything that happened while I was asleep."

Stacy giggled and said, "Well as long as you're asleep I would guess you'd be safe. The girls in school say that the only safe man is one who is sleeping or dead. And I sure don't want you dead."

I smiled and closed my eyes while my sister-in-law continued sitting on the bed facing me watching TV over my shoulder. I didn't waste any time acting as though I was dozing off and laid there with the sheets turned down just in my p. j. bottoms with one arm under my head and my other hand out in front of me, resting on the mattress between us.

As I lay there, I was constantly attuned to every sound and of course to the sweet smell of her clean young body. I tried to act as a sleeping person would, breathing heavier as if in a deep sleep and unmoving.

Shortly thereafter, I felt her shifting and as I excitedly waited, the youngster then lay down herself, facing me with her head propped up on one arm, as though to continue watching TV, with her free hand out in front of her next to mine.

After a couple of minutes in which I remained unmoving, the 14-year-old placed her hand over my hand and let it rest there. The touch and warmth of her hand was arousing in itself to say the least. Then she scooted a little closer to me so that our hands were right up against her right breast and paused. My heart was beating about twice its normal rate. Stacy obviously thought that I was asleep and was being the dangerous young teen. Very slowly she began caressing the back of my hand with hers.

It had been a long time since I was as excited as then. If she were older, I would have dispensed with the subterfuge and threw her onto her back and fucked the ass off of her. However, I was pretty sure that my little sister-in-law was a virgin; at least that was the image she always portrayed. I guessed that she was probably very unsure of herself at that moment.

Then almost unexpectedly she gently picked up my hand and brought it up atop her sweater, cupping her right breast with it. My cock was actually in pain, I was so hard. Her breast, which was about the size of half an orange, was taut and full. It took all my willpower not to begin squeezing it, allowing Stacy to hold my hand to her instead.

Still pretending to be asleep and stirring a little, I mumbled, "I love you sweetheart," as though being half-asleep talking to my wife. I then gently began fondling Stacy's B-sized breast through her sweater. I had never in my wildest thoughts ever imagined that I would be fondling a 14-year-olds tit, and Stacy's had to be the fullest, firmest, breast that one could ever hope to get his hands on.

Now that I started moving without freaking the youngster out, I became a bit more daring, next moving my hand to her left breast where I continued my fondling of her and was pleasantly surprised to feel her small nipple swell and harden in the palm of my hand. Oh my god, the youngster was aroused! Feeling bolder, I slid my hand down her side to the base of her sweater and as I began to slip my hand under her sweater, Stacy shocked me. To my delight, she reached down and pulled her sweater up, allowing my hand to slide onto her incredibly soft and smooth skin, her stomach actually quivering under my fingers. I then slid my hand up and once again cupped her left breast, now only the bra was between the palm of my hand and the swollen flesh of tit.

I continued to fondle her until eventually she reached up and grabbed my wrist and pushed my fondling hand even tighter against her breast. My cock suddenly erupted in my pants. I was never this worked up in my life. It had to be her age and her innocence, along with the potential for danger. As I continued to fondle that wondrous tit-flesh, I felt the youngster all of a sudden stiffen up, shudder, and tremble beneath my hand. Stacy was fighting a moan as she was obviously experiencing an incredibly powerful orgasm.

Wow, we both got off at nearly the same time and it seemed to satisfy my little sister-in-law.

After having settled down she gently laid my hand back down on the bed and got up and left the room. I was unsure what she was up to, but being that she hadn't shut the TV off, I lay there hoping that she would return. Realizing that she might be feeling guilty and remorseful, I began praying that I wasn't a dead man in the morning.

Then, to my relief, she returned. As she came into the room, I squinted open my eyes and as she moved in the darkness toward my bed, I saw that she had changed into her t-shirt nightie.

Happily, she moved up alongside me on the bed. I was very excited. Obviously, my little sister-in-law was feeling naughty and somewhat brave. Just how brave, I didn't know, but I was sure to find out.

I continued to act as though sound asleep like nothing happened. Then, once again, I felt that now familiar hand over mine and Stacy again moved my hand to cup her right breast over her sleeper t-shirt. I heard her intake of breath. Not wearing a bra this time, her naked breast felt incredible through her t-shirt. I immediately felt her small nipple swell in the palm of my hand. Just feeling her young, full, firm, breast rolling freely in my hand would certainly have been enough to make me cum all by itself if I hadn't just shot my wad 10 minutes earlier, but I was happy I wasn't ready yet. I genuinely wanted to see just how far all of this was going to go.

Still feigning being asleep, I mumbled something incoherently and began rolling the youngster's nipple between my thumb and forefinger, cupping and fondling her breast with the rest of my hand.

I wanted to rip off her shirt and panties and fuck the shit out of her. I was so hard it was almost intolerable but the only way I had a chance in hell of not going to prison was to fain ignorance and innocence. I was breathing erratically as Stacy gently scooted right up to me placing her forehead against mine and moved my arm around her which landed my hand right on her ass. I was in purgatory, between heaven and hell, not being able to just fuck her brains out, but wanting desperately to do so, all at the same time.

Having to act as if I was a sleeping body, I again mumbled something incoherently and pulled my young sister-in-law tighter to me, enjoying my hand on her ass with my cock pressing tightly into her groin. Not sure just how far she was willing or wanting to go, I simply just held her and mumbled, acting as though I was talking to my wife, "I am so in love with you." Then, I waited for Stacy to make the next move, hoping beyond hope that there would be a next move.

After about 2-3 minutes of just lying there with her, Stacy gently reached in and softly kissed me on the lips. I let my lips part just a little and felt her tongue gently brushing my lips almost as though she wasn't sure what she was doing, which might have been the case. I then extended my tongue until it gently brushed hers and at first she just softly played with the tip of my tongue but after a while she grew more aggressive until we were gently fully sucking on each other's tongues. I wondered if my 14-year-old sister-in-law had even been truly kissed.
