I went up to the roof of my building with my friend Cathy and Linda, one summer night. We usually liked going up there to get away from heat. Cathy came rushing over to us and in a low voice told us she just saw a naked boy laying on his bed stroking his dick. We rushed over and saw him spread out bare naked on his bed with the curtains wide open. We just couldn't take our eyes off of him, stroking away at his huge hard dick. We were getting the sexiest show of our lives and determind to see him shot out his load. It took him around ten minutes to finally cum and got to see the squirts of sperm shout across his chest. We all ended wetting our panties and horny as hell watching him masturbated. Since then, we all go up to the roof at night to see if we catch him yeking off again. The funny thing is that we sometimes bump into him in the street, and he dosen't have a clue that his been spied on by three horny teen girls. I,m sure that the three of us are embarrassed to confess, that we've been fingering ourselves off to it. Personally I would never tell anyone I've been fucking myself with a hair brush handle and working myself into a frenzy three time a day, thinking it's that's guy's dick inside me. I wonder how embarrassed he would be, if he knew we were watched the whole thing.
