#409233 - It wasn’t a pee-stain either; no argument about it, it was the remains of a cum-stain! So here I was, standing in the locked cubicle, leaking pre-cum like mad into my own damp Speedos, now barely containing my painfully trapped and engorged tool, and in my hands I had a pair of someone else’s cum-stained swim-shorts! I began wondering if he had actually aroused himself and cum while he was in the pool wearing them. “My size,” I thought, as I immediately began to picture the kind of young, fit guy who might have worn them; I imagined that I might have enjoyed a “Tumble” with him and I began to get a hard-on. The shorts were well-dry, so the guy probably wasn’t still here.
