I share a home with a few other guys about my age. My room is downstairs and has it's own exit. Jeff's room is upstairs just off the back porch. Jeff is a fairly good looking guy with a great body. I've always wondered what it would be like to spend an evening in bed with him.
One night, we'd been out trying to pick up these two cute ladies. Nothing worked out so we came home horny. We said goodnight and went our separate ways. I knew if Jeff was half as horny as I was, he'd be rubbing one out before going to bed.
So I went outside and snuck up the back stairs and peeked through the blinds in Jeff's room. Sure enough, he had the TV playing some porn and his hand was under the sheet rubbing his cock.
I got so excited seeing this. I'd never before seen a guy stroke himself. But I started getting pissed that he kept the sheet covering himself. My mind was racing, 'Come on you idiot, pull that damned sheet down! Who jacks off under a sheet?'
But as he got more intense, he did finally pull that wonderful cock out. I always thought he would be larger than me, but it seemed to be the same size. It was so fascinating to watch him pull himself. He did so with his dick pointing right at his chin, where I jack off with it pointing straight at the ceiling.
I loved watching his face, a face I see all the time in other situations, but now I was seeing it in his most private and intimate moment. I looked back to his dick, which he was rubbing really hard now. I could tell he was close to cumming as his feet started to tense and he threw his head back, no longer watching the woman on the TV get pummelled by her man.
Then, he spurted a few ropes, but most of his cum pooled in a puddle on his six-pack abs, just left of his belly button. He reached under his bed and got a towel and started to wipe up.
This is when I thought it would be best if I snuck back downstairs. I got to the bottom of the stairs and took out my engorged dick and rubbed one out right there under the half-moon. I could hear my jizz hit the pavement.
It was fun when I saw him the next day. He mentioned having a good solo session before going to sleep the night before. I wondered if he knew I was watching. But how could he have? I never let on that I did. But it was fun getting to see a new side to my housemate.
