My friend 'bob' and I would sleepover each others houses fairly constantly. At the time which this occurred we were both 16. One night we were bored so we started talking about masturbation, girls, sex, etc. I had gotten a hard on just from talking and so had bob both still fully clothed. To gain a better image Bob was around 5'7' and 5' hard and I was around 6' and 6' hard. We both were really tired so nothing else happened that night we both just fell asleep. In the morning we were just lying around, and yet to start talking from waking but no one was home in my house. All of a sudden I notice a bulge under the blanket which bob was laying under. He started to flex his cock under the blanket and soon I had begun to do the same. Eventually bob pulled down his blanket and exposed his rock hard dick. Anti-climatically, nothing else happened that day and bob left a few hours later that morning.
Next weekend bob came over to spend the night again. Similarly we started to talk about the same subjects as last time. Except this time it lead to us watching some cable porn. About half way through the show we both had nonchalantly slipped our hands under our blankets and began jerking off slowly, refraining from contact between each other. During this I could see bobs hand moving slowly up and down his dick which was really turning me on, and what I believe was the same for him. A few minutes later I heard bob let out a soft moan and cum under his blanket. He then went to clean up in the bathroom. While he was doing this I threw off my blanket and masturbated feverishly until I shot three or four ropes of cum onto myself. When we had both cleaned up we fell asleep pretty quickly.
In the morning I awoke with a hard on and bob, seeing this began to touch my feet. He started moving his hand up and down my leg while I was flexing my penis while acting asleep to encourage him to proceed. He then reached my thigh and had run his hand up my shorts and was dangerously close to my balls. With my anticipation at a max and my cock hard as a rock he finally began to slowly massage my balls. Still pretending to be asleep I flexed my penis more and he then snook his hand gently on to my penis and began to stroke ever so softly.
My cock twitched in his small hands I began to move my hips to the rythym of his hand. Shortly, he removed his hand from my member and then smoothly slipped off my shorts and boxers. My penis then sprang up at 90 degrees and awaited the warm grasp of his hand. Once he had placed his hand back on my cock he started slowly by moving up and down while massaging the tip of my penis ever so gently. He then placed both hands of his on my cock and I started to thrust my hips to move my penis in and out of his grasp.
After I tired of this he went back to jerking me off and soon I was reaching my climax. With my eyes still closed I began to feel my balls constrict and the cum start to flow up my penis. Bob started to stroke even faster and I shot almost seven full ropes of cum all over our bodies.
After I cleaned up and came back to the room bob had already slid down his pants and started to play with his fully erect 5' penis. I lay next to him and enclosed my hand on his cock. Right away he was into it and he was moaning quietly. I even pumped his cock and enjoyed feeling his penis flex as I held it in my hand. Soon after he said, 'I'm cumming' and he pulled up his t shirt. I then felt his cock bulging in my hand as he began to unload his cum. Tighten his balls dry he emptied his load all over us. Since this occurred we have never done anything like it since we both had taken interests to girls in our school.
