We were having an autumn heat wave, a couple weekends after Labor Day, and to make the most of it, I had gone with a buddy from work, along with some other friends to a recreation area at a nearby lake where we hung out, jet skied, waterskied and tubed and just spent the day swimming and goofing off. It was late afternoon, most everybody had loaded up and gone home, but I was staying in a tent, planning on extending my weekend with some fishing in the morning. The weather was expected to be cooler, the campground was nearly empty, and I was beginning to look forward to the fishing.
But today, I was sunburned, dirty and tired and I decided to get cleaned up. Adjacent to the campground there was a bath house, with showers, toilets and such, so I grabbed a towel and went into the shower to wash the 'lake' off.
Nobody else was in there as I entered the bath house. I took the first shower stall and I took my time, first washing and then just relaxing. At one point I thought I heard another shower start, but I was enjoying the shower, the cool water felt good on my burnt skin and it was kind of putting me in a horny sort of mood that got me looking forward to an evening alone in my tent in a deserted campground.
After I got out of my shower, I was sitting on a bench in the changing area, drip drying with my towel draped over my head and my legs splayed and a semi hard dick all exposed and dangling and I heard the other shower stop. Then the rustle of another person's towel then the rattling sound of the shower curtain and rings, but then nothing. I expected wet foot steps on the floor, a cough, or something, but there was not a sound. A moment later I pulled my towel off my face and saw my buddy as he stepped out of the other shower and stood there, wrapped in a towel and just looking at me. I pulled my knees together and sat up a bit as I tried to arrange the towel in my lap. Under his wet towel I could see the outline his dick bulge, which was also half hard. I was waiting for him to make joke or say something to ease the sudden strange atmosphere in the room.
Both of us were now in our late 30's, but we've been friends for a long time; since grade school actually and had spent our lives running in the same circles together; school sports, summers, camp-outs, hang-outs, school events...just everything, and we've shared just about everything; jackets, coats, shirts, pants, even undies. Homework, lunches, sodas, beers, smokes, I mean just everything.
There had also been a few fights, alot of grab-ass and horseplay and joking around, like guys will do, and it seemed like he was always making a joke or pranking someone. However, what he was doing right then was different, like he wasn't goofing. It was a bit over-the-line and awkward and made me feel a little uneasy. I avoided eye contact, but I could see him and I realized he was now slowly moving toward me.
He'd dropped the towel and was now nude. His dick was now fully erect as he edged toward me. I waved him off with a non-verbal sound meant to let him know to "cut it out" or knock it off" and I put my right hand up in a 'hold-it-right-there' gesture. In another second he had stepped up to my outstretched hand, which I was now using to create and maintain a space between us as my mind raced. This was just exactly the kind of joke he'd play and I really didn't feel like like living down the teasing as he related the story later to whoever he thought would laugh.
My hand was now resting on his chest. He was directly in front me. His dick was just getting harder and longer, and just way too close, so I pushed him back a little. To stay in contact, he quickly covered my hand with his and held it against his chest. Alarms were going off in my brain as I tried to process everything and decide what to do.
