When I was a 17 year old boy my best friend was a 17 year old black kid, we'd been friends since second grade. He had a brother that was 3 years younger than he was, he was a brat and I hated it when he came around or went with us. But one sunday afternoon my feeling for him changed, the three of us went to his uncles place outside of town to swim in the stream that runs through his place. My friends uncle wanted him to help him do something, so me and his lil bro went on to the stream. We swam there often and always went in naked, that day was the same, the water was warm and felt good. I didn't plan on this happening, cause I really didn't like his lil bro, but he's the one that started it. And for some reason I didn't or couldn't resist his advances, and by the time we started back to the house I'd let him fuck me three times. As far as I know my friend never found out about it, if he did he never said anything, but he did ask me why I never said anything bad about his lil bro anymore.
