When I was I child my mother married a new man. This man had a son 2 years younger than me. In that period I was experimenting with girlfriends; I tried some but had not at that time found the one that I would like to have sex with or maybe I didn´t have the nerve to ask.

Anyway I only had sex with myself, which I normally had every day in the period from my fifteenth year and the next 3 years till I had my first sex experience with a girl. Often I went straight to the bathroom right after school

One day I noticed that my stepbrother also went to the toilet everyday after school and I started to wonder if he was masturbating as well. I spend some days trying to figure out how to spy on him without him noticing me. Eventually I found out, that if I was lying on the floor in the livingroom, I could look out in the toilet because there was this gap between the door and the doorstep. All I could see, apart from the bathroom floor, was lowest part of the toilet and the lowest part of the radiator next to the toilet. I was disappointed cause I was really exited by the thought of him jacking off at the toilet 2 metres away from me. As I wasn´t able to find a better way spying on him, I decided to look out through the gap at the bottom of the door. It was a huge turn on to find out that the steel pipe leading from the floor to the radiator, acted as a primitive mirror and I was able to see the reflections from my stepbrothers hand on his dick when he was rubbing it. I was so exited and got even more exited when I could see his feet, that were placed on the toilet mat spread apart from each other, being pulled together as he came. Often he even curled his toes but even though I watched this facinating sight a lot of times, I never heard a sound.

Normaly I would go to the toilet right after him. I could feel the heat of his thigh that obviously had been spread apart. I would place my thigh in the same angel and jerk off to the thought of him jerking off or even to the thought of him sitting beside me and jerkng me off. I normally came in very powerful orgasms.

From time to time I discovered a little bit of his cum on the board an I licked it up and enjoyed the taste. I even brought his used pants with spots of dried cum in them when I jerked off. It was such a turn on.

One time when he was taking a bath in the tub I excused that I had to use the toilet. My dick was so hard when I leaned forward an silently rubbed myself to orgasm, trying to hide my dick below the edge, and not to make any sounds. The exitement of bringing myself to orgasm with only a thin curtain an 1 1/2 meter between us made me cum very fast.

When I found a girlfriend that I could have sex with these fantasies stopped.
