of the night. I turned away from his bed, towards the pock-marked wall, with a pillow over my head to try and block out the increasing brightness coming in through the curtains as the sun rose in the sky. I expected to hear Peter get up and leave the room to make coffee and use the bathroom or whatever, but he stayed in bed, apparently in no rush to get up for work.

I guess I left him ten minutes or so, thinking that he was maybe dozing or had pressed the snooze button on his alarm clock. Then I figured he'd gone back to sleep and so turned over to face him, intending to call over to him and wake him up.

I found, as you've probably anticipated, that he was in full swing. He'd pushed the duvet aside, and was lying there, totally naked, masturbating his foreskin up and down his fairly impressive looking cock, totally devoid of self-consciousness.

At first I felt pretty surprised, maybe even a little embarrassed. I should say that I'm no prude - I went to a boys' boarding school and so masturbating with another guy in the room is hardly new to me - but I guess I was taken aback by the sheer candor of the guy. If I was going to have a wank while sharing a room, I'd do it under the covers, as quietly and discretely as possible; or, more likely, would wait until I was in the toilet or taking a shower. Not so Peter: he just kicked the duvet to one side and jerked away at his dick as openly and unworried as if he were stretching or scratching himself.

I felt an immediate instinct to look away: to leave him to get on with it without a spectator. But then I noticed that his eyes were closed. In any case, it occurred to me that, as he'd obviously heard me moving about in the room after his alarm had gone off, my presence was clearly irrelevant to him.

So I took the opportunity of watching him for a while. Out of curiosity, you know.

His bed was on the opposite wall to mine and so I was looking at the length of his body from his left side.

He was well-built, reasonably muscular guy and his chest and legs were covered fairly thickly with black hair. His feet, like mine, protruded from the end of the mattress and so I'd guess he was slightly over six feet tall. His expression was serious and his rhythm was moderately fast: he was obviously intent on reaching his orgasm fairly quickly and without any unnecessary delay. In fact, I think the idea of a guy savouring his masturbatory pleasures was pretty unknown to Peter.

He just lay there for a couple of minutes: his hand doing its thing on his cock, his face expressionless and his breathing apparently normal. Looking like he was just doing it for the sake of it: almost like it was a chore he was attending to.

Masturbation as a bodily function: that's what it looked like.

I took a good look at his cock. It was large - about seven inches or so - and fairly thick. His foreskin made a slap-slap-slapping sound as he jerked it up and down his length. His bell-end wasn't especially
