It had been a hard long day and a session in the gym was just what I needed. The changing room was empty so I slipped out my suit quickly but decided to keep my knickers on under my tracksuit pants. They were a pair of black trunk style briefs with lycra in so I knew they would hold me neatly in place as I made my way around the bikes and other equipment.
An hour later and I was done and pleased with my efforts. I made my way back to the changing room and found it quite full. I started to pull off my clothes and get ready for a shower and as my tracksuit bottoms fell to the floor, I remembered what I was wearing beneath! There must have been about 10 blokes in there and my heart stopped. I acted all natural and took off my teeshirt. They were not at all frilly, just black with a sheen to them so there was no reason for anyone to think anything of it. I slipped out of them too and locked my gear in the locker and headed to the shower unit.
The shower area is open plan with about 6 shower heads in a 3 by 3 metre space. I set the water on hot and let it run over me for a couple of minutes. I was aware of people coming and going, but paid no attention. Until I caught two voices over the sound of the raining water. I thought I may have been imagining it but as I strained to hear I could definitely make out the words panties, knickers, cock and arse.
I tried not to focus on the words, I could my cock already swelling into a semi. I turned in the shower faking a rinse off, but it was just to look at who was in here with me. The two guys looked away quickly allowing me to check them out. They were both average, and about my age of 30-35. Of course I checked downwards and my gaze fell on to nice looking cocks, one flaccid and about 4 inches long and the other I guessed was semi erect, it hung down but was 6 inches or so and pretty thick.
Oh no, I thought to myself, what a mistake to make in the gym showers and low and behold as I turned my back to them my won six incher started to stand to attention.
