I was in college when I first started having sex with other guys.  At first it was just mutual jerk-off sessions, then there was "a little help" for each other, and then handjobs before I finally gave my first blowjob (described elsewhere here). Still, there were only two guys I was doing it with, and all of us kept it a strict secret.

There was a guy in two of my classes named Pete, who might have suspected I was bi, but didn't know it for sure. Pete was about as tall as I was, but had a more muscular build. He was a bit of a jock, playing hockey and football on the school teams. We both liked sailing, but he lived in a subdivision and I lived on a lake. At the end of the school year, I told him to come over to go sailing anytime he wanted to.

One time when he came over, the rest of my family was away at my grandparents for the week, and Pete and I went out for a late afternoon sail. We got out a little too far, and were taken by surprise by a thunderstorm that blew up quickly. We headed back, but got caught in the rain and drenched. Just as we approached the dock, a gust caught us and we nearly capsized, losing our spare lifejackets in the process. We released the sail, and Pete jumped out and pulled us to the dock. We got the boat tied up and went into the house. Although it was quite warm out, the wind had given us a chill. I told Pete he could have the bathroom first for a hot shower.

After undressing in the bathroom, he leaned out the door and yelled, "What should I do with my clothes?"

"Leave them in the sink" I said, "I'll loan you a pair of my jeans until they're dry."

I handed him a pair of sweat socks and an old pair of Levi's I had that were ripped at the knees.

"That's all?" he asked.

"Well, I'm not loaning you my underwear" I told him pointedly.

"I meant a T-shirt,” he laughed.

Pete had a quick shower, and came out to the family room with one towel around his waist, using a second one to dry himself off and carrying the jeans. I went in and had a quick shower myself. I dried off, and pulled on my other pair of Levi's 501s (newer and in better shape!), but no underwear, as I often went without around the house.

I picked up our wet clothes and started towards the laundry room. Pete was sitting in the family room watching the TV. As I came back from throwing our wet clothes in the washing machine, Pete stood up and I gasped. Pete's a little heavier than I was then, and those jeans were really, really tight on him - and he was showing a huge cock and plainly visible balls tucked down one leg.

I knew Pete had seen my reaction, and I mumbled something as I turned away to hide my stirring erection. I went to my room and grabbed two T-shirts from my drawer, pulling one on and leaving it out so as to hide my crotch. I returned to the family room and tossed the other one to Pete without really looking in his direction.

Pete got up out of the chair
