Hi my name is keith and i'm 17 years old. I have a brother Paul who is 19. My story happenend 3 years ago. I had just arrived home from soccer practice when I saw my brothers bike leaned against the house. He was usually at his friends house around this time and i would come home to an empty house. On entering the house I left my boots at the back door and got a drink. I started to walk up the stairs as i got to the top of the stairs my brothers door was slightly open but he had his red hot chillis album on dead loud. I was about to walk in and tell him to turn it down when i could see through the crack of the door he was jerkin off. I was totally shocked yet at the same time slightly aroused and so continued to watch. Iwas at this point gettin a full hard on as i was noticing that while he was stroking his cick he was caressing his balls something that was totally turnin me on. I pushed the door open a little further but not so much as he could see me and pulled my shorts and boxers down. I then started to stroke my own 7 inch cock to the same rhythm as him stroking his 8-9 inch cock. Justas i was really getting into it the music cut off and as he turned around to change the song he spotted me and i ran to my room.
After around half a minute he opened the door to my room and asked me what the hell i was doing i told him i was sorry and that it would never happen again but it was so horny i just couldn't not jerk off.
