I didn't like my baby brother at all. There was two years difference between us and for the most part we kept away from each other. By the time I hit puberty he was nothing more than an annoying little shit. My dad thought he was the greatest thing in the world, but had little time for me, which, I guess, made me hate Stevey all the more. Dad didn't work, but mom held two jobs down.
So into puberty I went and out the other side. By the time I was 15 I was pretty much developed and masturbating a lot, and I mean a LOT. I think I compensated for being left out so much at home. I used to jill off at least once a day, but often two or three times.
Stevey suddenly started to disrespect my privacy. He would walk into my room without knocking, or I would find him in there. He would also take stuff that was mine like my MP3 player and when I got it back, he had wiped it. Generally, he was a little shit.
I don't think I actually realised at the time that he too was starting into puberty. That is, until one evening. Dad finally got off his ass and got a job and he and mom had gone out to dinner. I finished my homework and cleaned up the kitchen. (No WAY was Stevey going to help!)
I walked upstairs and into my room.
There I stopped in my tracks. Stevey was standing in my room, his cock in his hand and my panties in the other. In that moment I knew what towering range meant. I flew at him and starting beating the crap out of him, and calling him all the names in the world. I knocked him down, even though he was bigger than me and I was punching and slapping every inch I could get at.
I didn't realise that I had straddled him, OR that his boner was pressing between my legs. That's when it happened. Suddenly, all the anger and all the hate I felt seemed to evaporate into lust. I was suddenly aware of his shaft and my panties (and clit) rubbing it. I started grinding, pressing down really hard on it. Suddenly I felt myself cumming and it was fucking HUGE. I really creamed up and it just kept coming. Looking down, I could see the head of his cock slipping forward and his pre-cum was staining my panties which made me cum even more. I must have had three consecutive orgasms.
Stevey by this time wasn't far off either. I reached down.
I won't say what I did, but I saw the moment Stevey came. His eyes popped WIDE open and I felt him convulsing.
Later, in bed I thought about what I had done and had to jill off again.
Since then, Stevey became totally wonderful. Kind, thoughtful, respectful and now, years later, we are good friends. We also still fool around a little from time to time.
Incest.. well yeah.. DUH. It happened. Do I regret it? Not a damn bit.
