I Would Never Have Believed It

I love ST. I've been reading it for about two years now and have noticed the increase in the number of incest based stories. Now, I had not really thought that much about them to be honest. Its not that I thought they were weird or sick, they just didn't do anything for me other than make me think that "forbidden" fruit is always juicier. I have a sister who is 18. She is very tall and thin and has almost no boobs! We are good friends and this is just as well because we live in the middle of nowhere. We both hate it! Someone once asked me what my home town was like. I told them that if ever my country needs an enema, my home town is where they would put the tube! My sister, Sarah, often jokes about her appearance. She once told me that her bra size was the same now as it was when she was 12. One evening, Sarah and I were just chatting in general, although I could tell something was on her mind. After a while she asked me if she would ask me something. I said sure. She said "Allan, when you feel horny, do you just like go for it or do you use porn or something?" I wasn't freaked by her questions because as I said we are good buddies as well as bro/sis. So I told her that I like ST. She hadn't heard of it and I offered to show her the website. We went up to her room and I found the site for her and showed her how to get at the stories. Then I said I would leave her to it. Instead, though, she asked me to sit with her for while. We read story after story and, as usual, I got a raging hard on. I think it was getting to Sarah too, because she was breathing really deeply and kept squeezing her legs together. Then, as she clicked the mouse she let her hand fall right onto my lap and my hard on. I leapt up and said, "Time to let you finish." Sarah swiveled around on the stool and let her legs part. I could see she had a pair of green cotton panties on, but what really had my attention was the huge damp spot that made the material look almost black. Sarah shucked her skirt up and pushed her hand into her knickers. Suddenly, I knew I was leaking pre-cum too, and I stood there and unzipped myself. For a moment we just looked at each other masturbating. Sarah suddenly stopped, stood up and slipped her t shirt, skirt and knickers off and went and lay on her bed. I stood next to her watching her masturbate. All the time my head was buzzing with: "Fuck, dude,,, this is your SISTER!!" All it did was to make me hornier. Sarah asked me to kneel up on her bed between her legs and for a moment I really thought she was going to ask me to fuck her. We masturbated hard and fast like that and Sarah arched her back and had a great orgasm that involved her creaming her hand, then the bed and my knees! I leaned right back and shot my load. I don't know how many ropes of cum I let go, all I know is that it was the most intense orgasm I have ever had. When I looked at her, I had shot my load onto her face, her tits, and her pussy. Sarah reach up and pulled me to her and we just hugged and cuddled. I could feel my cock against her pussy lips and as we cuddled I think I entered her a little, but not much. I went to bed that night buzzing with what we had done. The next few days I found myself totally obsessed by it. Sarah did too, because she took opportunities to flash me. I found her panties in my bed two nights ago with a little note that said "Fill these." Of course, with her aroma on them I did and I walked to her room and handed them back to her. She fingered them and smelled me on them and then, to my surprise, she slipped them on, pressing the sperm filled crotch up against her pussy. A few minutes later, I could hear her jilling herself off. There is no doubt that forbidden fruit really IS sweeter. I know we wont go all the way, but we are both exploring this lovely new world!
