This happened about ten years ago, with my best friend, Jeremy. We were both in college and we were still living with our parents. I was over there one afternoon just hanging out on the couch in their basement rec room. I was sitting at one end and Jeremy was laying with his feet across my lap. I always thought that Jeremy was a good looking guy, and I couldn't take my eyes off of his crotch. I had always wondered how big he was, and I thought, 'what the heck, today's the day.' I reached over and started rubbing the bulge in his jeans.
His body sort of stiffened up, but after a few minutes the rubbing must have started feeling good, because he relaxed a little. He closed his eyes and soon my hands were fumbling with his belt, and unzipping his pants.
I was rubbing his dick through his briefs and he let out a little moan. I pulled his jeans down past his knees and tucked his underwear under his balls. His dick was a thick seven-incher with a nice pink flared head. I started rubbing his dick faster while tickling his balls with my other hand. His breathing got deeper and he was moaning and gasping.
My right hand was the one that was on his dick and he put his hand over mine and guided the speed that he wanted me to go. He really liked it fast and hard, both our hands were a blur as we jacked that stiff rod. I could tell that he was about to shoot because the pink head was turning a darker hue.
Suddenly he moaned real loud, his hips rose off the couch and he pulled his t-shirt up just in time to blast a big load of cream on his stomach.
After several squirts his body relaxed and I rubbed his sperm over his abs while his breathing returned to normal. After a few more minutes he got off the couch and without a word, headed for the bathroom to wash up.
