Today was the closest I ever came to stealing underwear at the gym. while I was working out I was watching a cute guy with a great body, he was wearing a shirt with the sleeve holes cut out far enough down that you could see his naked abs and pecs from the side and an occasional glimpse of his nipple. he was short and olive-skinned, 95% sure he was gay. When I was getting dressed after my shower he came into the locker room and started stripping for his shower. He did the "towel dance" and I noticed he didn't put a lock on his locker. When he walked away and I heard the shower go on, I couldn't resist, I opened his locker. I looked down to see a pair of 2xist briefs still nestled in his jogging shorts. I reached in and grabbed them, still not sure if I would really take them or just check them out. As I lifted them I noticed a thin piece of foam in the pouch. If reminded me of the foam sometimes used to make cushions, but it was maybe 1/2 inch thick. He was stuffing his bulge! I quickly dropped them back in the locker and left. It's interesting, because I wasn't looking at his bulge when he worked out, usually I do look down there but this guy was showing off his upper body so much I don't even think I looked down.
