My best friend Danny was invited for a sleepover which we did often. I have a double bed and we sleep together when he's at my house.
We went to bed a little before 11 and I sat reading a magazine. He lay down and was sleeping almost straight away, I could hear him breathing.
Fast forward two hours and no matter what I did I couldn't slip into sleep. As it was really hot we had removed the bedclothes and I looked down at Danny who was deep asleep. What I saw next was amazing. He was on his stomach and gently he was humping the bed, I could see his butt clenching as he did so. He had his face to me and I could see he was still sleeping. I gingerly reached out and cupped one of his tight buttocks feeling it clench under my hand.
Then he turns over and I saw his erection poking out of the fly of his boxers. He was moaning in his sleep and as I watched he gave a huge grunt and semen pumped from his lovely penis. I was so turned on that my best friend had just had a wet dream beside me.
I reached out and got some of his semen, and rubbed it on my hard penis and wanked off right there.
