It had been too long. It had to happen.

100% fiction!

I was well into my eigth year on a fifteen year prison sentence for robbery when the unthinkable happened. Either my mother or my sister would come stay a couple days on in the prison sponsored conjugal visit program, designed to help hold families together. On this one particular visit my sister came up with her daughter and the visit proceeded to go about as they normally do. She would update me on the latest news while I helped her unpack the food bags. She would then head into the two bedrooms to make up the beds with the sheets she had brought from her home. We never used the sheets and towels provided by the facility.

While my sister and mother were merely happy with spending time with me, I also enjoyed being away from the prison for a few days and of course selecting DVD movies with the most sex scenes in them from the prison library. Families were not permitted to bring in any DVD's though many families did. I never asked it of my own family. I would just choose a Monsters Ball or Basic Instinct and wait for my family to fall asleep. The me time I spent jerking off into the wee hours of the night.

Later that evening while my niece had dozed off on the couch I sat in the living room, which was open to the kitchen and channel surfed until I got distracted by a female beach volley ball game. The time spent in prison had literally made me a pervert and nearly anything caused a rise in my pants. I was still in the throes of the game when my sister called to me from the open bathroom. I attempted to hold on a few seconds while my hardon abated, but to no avail. Her second call was much more insistant and I walked into the bathroom trying to seem normal while shielding my cock. Her head was halfway under the water and she wanted me to wash the back of her head. I had done it on occassions before and reluctantly agreed to do so again.

A strange thing began to happen to me as I waited behind my sister for her to soak her hair. The sweatpants she wore were a tight number with the spelling across her ass and I found myself suddenly noticing and admiring the shape of my sisters ass. The more I stared the hotter my insides became--and of course the harder my dick became. I removed my wrists and my buldge strained to break free of my own sweats. Breathing a bit heavier, I looked down at the six or so inches between us and swallowed hard as I leaned further on the balls of my feet until my dick was literally a sheet of paper away. I rotated my hips imagining running my dick across her ass--but suddenly she was ready.

I got behind her and suddenly realized the delima as I stood poised behind her with her awaiting me. My dick would stab her to death should I lean over her to wash her hair. Instead I manuevered to the side of her and began applying shampoo to her hair. The weird move was quickly noticed and I was instructed that I would have to stand behind her. Suddenly wishing I was plastic man I followed her orders. And while I didn't make a complete mess out of things, I was sure she felt me as her body stiffened at one point when she backed up abruptly. But she never spoke about it and so I got through the washing as quickly as possible and failed to forget about it.

Still later that night I was watching She Hates Me when I paused at my favorite scene and went to check on my sister and niece. While not under the covers my sister seemed sleep and my niece after waking up to eat was already back sleeping again. I went back to the couch and quickly undressed and got under the covers. The covers were for quick shielding. However, while I messaged my swollen dick to its full eight thick inches the covers were at my side. I guess I was too comfortable because I sensed her too late. But again she never said a thing as she looked me in the eyes before walking into the kitchen to grab a drink.

On the way back she avoided looking at me--or maybe I avoided looking at her. I was misreable all of forty seconds because then after briefly going into the bedroom she came back out and went into the shower. The door was left open and again I felt myself flushing. Rather than put back on my clothes I waited until I knew her to be in the water before easing up and creeping over to the open door. While the curtain kept most of her body secret, her silouet was inticing and I felt my legs weakening. I was drowning in lust. Then suddenly she yelled my name, startling me. She wanted me to bring her soap from out of her room. And this is how I know lust is intoxicating. I walked into the room and collected the bar of soap and took it into the bathroom to her. She looked out from behind the curtain, down at my heavy and bobbing dick and then into my eyes with a smirk. "You still jerking off?" She asked. I responded about movies being played out and hesitated a moment before she went back behind the curtain. I walked back outside and paced outside the door thinking of a move that would advance things, but I drew a blank, so lost totally loosing time.

Suddenly the water stopped and I kicked myself. I gave up on running to hide behind a sheet and went into the kitchen to drink some water. Then my sister came out of the bathroom and was a streak of flesh as she went into the room. I angled myself closer to the hall to catch more, knowing that there would be and then she exited the room and went back into the bathroom. Her shape was stunning and my dick was aching. And again I was called to help lotion her back. I knew I had to make it happen then or suffer the rest of the week. Completely naked, I walked back into the bathroom and she glanced down at my dancing dick and giggled before turning her back to me. She then removed the towel so that I could apply the lotion. She too was now naked. There was too much lust in the air for conversation and as I applied lotion I made sure to make sure that my cock was rubbed against her ass and back.

When I begin to notice her motions I knew it had to be then. I ran my hands down to her wasit and began to lotion her ass as she leaned slightly forward. I then ran my hands between her thighs, feeling her heat the closer I got to her pussy. I half expected her to jump when my hands connected with her swollen pussy lips, but she released a slight whimper. I then inserted a finger and she spread her legs further apart. I worked my finger in and out of her until I was able to insert another. I made sure to lather of her pussy before walking closer to her--"wait!" She wanted away from the bathroom mirror and I understood.

She placed her hands on the toilet and bent all the way over. I took ahold of her hip with one hand while lowering myself and aiming my swollen dick head at her pussy. She sucked in air as I pushed myself in halfway and when I pulled out she groaned. I continued to ease into her up to where her pussy juice mark was, before slowly pulling out again. I then took control of her hips with both hands and rocked her back and forth on my dick while looking down as my thick vieny dick eased in and out of her bald and moist pussy. Her walls were tight around my dick and before long she had made the adjustment. She began to rock herself back onto my dick< pushing off the toilet, breathing heavier.

I chanced a bit of noise and began slamming into her as well, smacking into her ass. Her yelps became more impassioned and we both gave up on noise control as she slammed herself into me hard while using one hand to paw at her pussy. I found a rythym and continued to plow into her--pulling out near the head before driving back in my full length. Then suddenly she tried to pull away while going silent, beginning to cum. I followed her, continuing to pump in as much as I could until I saw spots, followed by a heatwave traveling up my body until it lingered in my nuts. I pulled free just as a spurt shot out onto the small of her back followed by another that landed across her ass. I growled while squeezing out a few more drops, which she turned to take up with her hands and rub on her tities. I was amazed looking at her lotion her breasts with my cum. And I knew, the fun was only just starting.
