She couldn't stop

100% fiction!

My name is Eric and I live with my family in the suburbs of San Diego. My parents only had two kids, me 18 and my sister, Jesse 19. She goes to school in the city but is staying at home for college to save money. My parents have made so much of a big deal out of saving money that it seems like it is our only choice to stay home while we go to school. It's not so bad, though. My parents are retired from selling their old business and travel pretty regularly.

I always knew my sister was attractive, but I had never thought anything sexual about her until she started going to college. She started picking up guys, and since our rooms are right next to each other, I can pretty much hear whatever is going on. The first time I just sat and listened. The guy didn't sound like he was that smooth, but listening to the heavy breathing of my sister while this dumbass fucked her made me seriously think about what it would be like to be in his position...and how much better I would make sure I did when I fucked her. It never disturbed me. She was gorgeous; 5'6", black straight hair with a beautiful face, 32C tits and a perfectly rounded ass.

The next time she had a guy over for the night, I put my head up against the wall to hear better and pulled my dick out. I worked my cock slowly to their rhythm. The soft moans let me know that this new guy was doing better than the last. While I worked towards my climax, all I could think about was my sister's naked body. The pumping In the next room got quicker and quicker before there was a pretty noisy orgasm from both of them. As the pumping slowed I couldn't hold it any longer. I came hard, shooting 4 or 5 feet in front of me almost all the way to the wall. I kept working my cock until I had pumped it clear and wondered if I had made any noise that they could have heard...I mean, I can hear them.

This guy stuck around for a while and actually got introduced to the family. He seemed nice enough, but deep down I resented how he got to fuck my sister. Whenever I masturbated, I was thinking about her getting railed. Whenever I saw it in my head, it was my cock she was devouring or riding or beating hard. She dated Jeremy for 2 months before he dumped her. It seemed like it was pretty crushing for her. I wanted to make her feel better so I decided I would get her to roast a bowl of green with me and talk about it.

My parents had just left for a week long trip so we sat down in the living room and roasted a fat bowl out of my bong "Dillinger". It was obvious she wasn't used to the medical stuff and she soon started babbling. Talking about how Jeremy said he loved her, and she felt betrayed. Then about how the sex was great with him and she was horny. I immediately had a terrible and wonderful thought "you have a week to get your sister to fuck you". It was decided, I was going for it. I figured I would compliment her "you are hot jes, you could get another guy whenever you want". She blushed and smiled before pulling out another bowl to share. She hit first, and when I was about done hitting, she leaned over to get the bong from me and accidentally put her palm right on my chubby cock. Her eyes went wide, and it was obvious that it was an accident, but she left her hand there just a little longer than she should have, and while she had her hand there, I flexed my cock into her hand. She leaned back and we didn't end up talking about it for the rest of the night. I decided at that moment that I was going to save my orgasm until it was my sister that gave it to me...I had to work fast before our parents came back.

The next morning, I decided I would wake my sister up so we could hang out. When I walked into her room all that covered her amazing body was a single thin sheet. It was the most erotic sight of my life, and it was definitely hard not to pull it out right then and blow a load. I leaned over, put my hand on her shoulder and said "Jes, wake up". She sat up smoothly with her eyes closed and slid her tongue into my mouth. I couldn't believe it, what was happening? The kiss ended as she slowly slid back down to the bed, with her eyes still closed. "Let me sleep Jeremy" she moaned slowly. I shook her a little bit and she woke up abruptly. She sat silently for a second before saying "did I just make out with you?". I was still so shocked, all I could do was nod. She said she was sorry, and told me to leave so she could get dressed.

The rest of the day was chill and uneventful. We ordered chinese, and watched movies. After a while she asked if we could smoke the bong again. I was thinking I needed to keep going with my plan tonight...somehow I was going to get her to want to fuck me. I came back with the reefer and my bong and we smoked a ton. We started talking about porn at some point, and I told her about how I dug on blow jobs and big tits. "My favorite kind of porn is a chick who knows how to rock a cock doing just that". She grinned and told me she loves all kind of porn. Straight, girl on girl, guy on guy, orgies, gang bangs and even glory holes and bukkake. "What is it about all that stuff that you like" I said. "I love forbidden things, I love watching people receive pleasure. I always loved how you would cum with us whenever we would fuck..." She obviously said it without thinking. Her face flushed and she kinda froze. Now was my chance to make this happen and even have it be her idea.

I smiled."It's ok Jes, I should have known you heard. Come here" I told her and she sat next to me. I put my arm around her and said in a calm voice "do you have something you want to tell me?" She shook her head after a second and said "what do you mean?" I reminded her about how she touched my dick, how she told me she was horny, how she kissed me that morning. She blushed and said "fuck it...my favorite type of porn is incest porn. I have wanted to fuck you ever since I thought about you listening to me fuck my first college guy". "Wow all I've wanted to do was fuck you since that night" I blurted out. She grinned and asked if I wanted to start with some porn. I dick was already a rock in my pants. "Sure, but I watch porn naked" I said, and she just stripped off and said "Me too". We sat on the couch next to each other and put on some mother son incest porn Jes had stashed away. They started the film by walking through the house and looking at family pictures. This couldn't have been faked. The mother and the son were both quite attractive people, and Jes and I started touching ourselves...all I could think was "Success!".

It wasn't long before my leg was rubbing against hers. Her hands were the first the start exploring. She reached over and knocked my hands off of my cock. She grabbed my thick cock with both hands and a few inches stuck out the top. "big boy!" she groaned as she started pumping me with both hands. "I'm about to taste your cum Eric" she said as she leaned over and slid the extra cock into her mouth. I was in heaven. I leaned over and grabbed her tits while she slowly worked her mouth down farther and farther down on my hard cock. It felt like it went on for hours. She was a goddess, working me to the point where I could barely keep hold of it and easing me back just to do it again. She started moving a little faster, a little harder and completely steady. It wasn't going to take me long to cum. I felt my whole body tense and my cock expanded. At the moment right when i let loose, she slid all the way down till my cock disappeared and she worked back and forth hard and fast, probably unloading and ungodly amount of cum down her throat.

She didn't even miss a beat, and said "your cock is going to need a rest, why don't you figure out how to kill the time until you are ready again" seductively climbing on top of me and rubbing her tits on my face, letting me stop her and suck her nipple. My hands explored her body while my mouth and tongue played with her perfect tits. I reached my hands up and rubbed her back and pushed her against me in the process. As I held her against me, I rubbed myself against her body. I carried her into mom and dads room and put her down on the bed. My tongue traveled down her body until I was down at her cleanly shaven lips. I teased her, going in circles, then up one leg and back, making her feel the anticipation. I got into position and started working her clit with my tongue held flat, moving in slow strong circles. Her back arched and she cried out with some of the first peaks. Her taste and smell awoke my dick, and I knew it was time to make her cum before I fuck her. I focused pressure with my tongue and drew circles around her swollen clit. She howled a low groan of pure ecstasy while an intense orgasm rocked her body. It was difficult to keep my tongue in place but I kept going until she had to push me away.

"Too much, but oh god. You ready?" she asked, and i was already getting in position on her to slide myself in. I pumped slowly while going deeper and deeper. I rubbed myself against her clit while I pounded hard against her g spot. She melted into my arms as we rolled around with our arms around each other. She leaned up and licked some of juices off my face between peaks and said "please don't stop". I was a man on a mission. I pounded away, pulling her legs up over my shoulders, she closed her eyes and said " oOoOoh fuck I'm cumming" and the walls of her pussy clenched tight on my extremely swollen cock. My body shuddered as I came another intensely large load into my sister's pussy. I continues to pump for a while and all we could do for hours is kiss, not even pulling myself out of her.

And that was the first time it ever happened. Now we spend a good portion of the time naked while mom and dad are away, and we definitely still fuck while they are here :)
