defined - it was about the same thickness as the shaft of his cock and seemed to blend in with it, instead of being bulbous and clearly separated like a mushroom head as mine is. His balls were large and, like the base of his cock and the lower part of his stomach, densely forested by a tangle of wiry black pubic hair.

I noticed that his bell-end remained fairly dry as he masturbated, as mine does. There was a crude joke back then that my mates used to say about their cocks "dripping" when they saw an attractive girl, and for a while I'd wondered if my cock was somehow odd because it leaked so little precum when it was hard. But Peter's looked pretty similar and it was kind of reassuring to see that.

The smell of his cock was subtle yet unmistakable in the warm air of the room. It was the familiar smell of male excitement: as sharp and distinctive as the smells from girls and women when they get horny. I find the smells from females during sex an overpowering turn-on, and here the smell of Peter's male equivalent made me feel equally aroused. I felt my own cock stiffening rapidly in my briefs.

I rubbed myself discretely under my duvet as I watched him. The sight, smell and sounds of his cock were really turning me on.

I was surprised that he didn't use his other hand to caress his body, as I do when I masturbate. I fondle my balls, play with my nipples, rub my stomach, and sometimes even play around with my arsehole a little. But Peter just wanked himself with his right hand and his left hand lay motionless at his side. I considered that it might be because he was aware I was watching him, but, like I said, he seemed so disinterested by my presence that I don't think it would have affected his performance one way or the other. I guess that it was just his way of masturbating: relieving himself in a workmanlike and mechanical way.

He started breathing very quickly about ten seconds before he came. That also turned out to be part of the established routine. His strokes then became very rapid as he headed into his orgasm. With his free hand, he grabbed his discarded briefs which I guess were lying amongst the bedding at his side, and, as his cock started squirting, he cupped them over the top of his cock to catch his semen.

He kept gasping as he milked his cock into his underwear. His orgasm was fairly copious: some of his cum dribbled from his briefs and leaked onto his stomach.

After his climax had subsided, he just lay there for half a minute or so, still holding his cock with his right hand and his briefs over the head of it with the other, recovering his breath. The strong smell of his cum, thick and mildly-cloying, filled the air.

Then he threw his sticky briefs to one side and got up. I closed my eyes, pretending to sleep.

After he'd gone for a shower, I pulled off my briefs and masturbated my own cock underneath the duvet. I was really turned on by what I'd just seen and relieved myself urgently and breathlessly. I squirted into my dirty briefs, as he
