This happened when we were both fifteen.
One night I slept over my friend 'Joe's' house. We were up late, and his cousin 'John' was sleeping over too. So we went to bed, and in the morning I was the first to wake up. I started playing viedo games for a while until 'Joe' woke up. We were both in shirts and boxers. He walked by and said he had to piss wicked bad. So just joking around I said, 'Going to work off that morning boner?' He pulled his boxers down to show me his boner which I didn't even ask to see. So he was standing there with his hard dick hanging out and then he started putting it near my face. He kept telling me to 'suck it' but I didn't. So then I said, 'You're not the only one who's hard, ya know.' And he sat down next to me and started fondling himself, while staring at my hard dick through my boxers. Then he reached over and started playing with me. I stopped playing and reached over for his dick. This went on for a few minutes then his cousin started waking up so we stopped. A little has happened since once and a while we feel each other's boners, but we're both attracted to girls. We never talk about it, and act like it didn't happen.
