Have you ever fantasized about wearing someone else’s soiled underwear or swim-shorts? Well I have and I’ve got to write this down quickly because it happened only last week and it was one of the horniest, sexiest experiences I can remember!

It happened at the swimming-pool where I go two or three times a week, quite early in the morning. It’s a modern pool, shared with the Secondary School next door and sometimes the pool sessions during the day are shared too; on my days off, I’ve been there later in the day when the older boys of the Upper School are having their lessons – lean young 16 to 18 year-olds, nearly always wearing those baggy board-shorts; the serious ones sometimes wear compression-style “Jammers” but always in black, so you can seldom see anything unless you get very close-up, which you can’t. Never do you see any sexy “Speedos” these days. Even so, the senior boys can be quite distracting!

On this occasion though, it was early and fairly quiet. After my swim session, I was showering-off in the communal shower area and I noticed a small pair of swim-shorts left hanging on the hook on the wall opposite. Being communal showers, people don’t take their trunks or shorts off to shower, like they do at the YMCA, so it’s unusual to see any swimwear “abandoned” like this. At first, I thought they might belong to one of the fit young Lifeguards, having had an early swim when the pool opened but they mostly wear a corporate-style outfit of blue & red and these shorts were a greenish camouflage design with a pirate-skull logo on them that I didn’t recognize.

“Not really a man’s style of swimwear,” I thought to myself.

I took my time drying myself off, while the shower area cleared completely and I was on my own. I looked around to make sure no-one could see me and I took the shorts down from the hook and looked inside the waist-band, to see what size they were. “Small – 30-32 inches” the label said, “Do Not Tumble”. Inwardly I smiled.

“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. I looked around again and then quickly concealed the shorts in the folds of my towel and went off to the lockers and changing cubicles.

I’ve always had a fantasy about wearing someone else’s underwear or swim-shorts but had never actually done it. In the privacy of the changing cubicle, I examined them more closely. My cock was hard as a rock and leaking pre-cum already, as I tried to imagine when and how the guy had taken them off and left them in a communal shower area without drawing attention to himself.

The shorts were a soft, silky nylon material, quite short and loose in the leg and more like athletic shorts really. Their camouflage design was quite stylish (to my eyes at any rate) and they had a flimsy white mesh gusset inside. When I looked more closely, I experienced one of those rare frissons that run down your spine and then through your whole body, as I realized that the gusset was stained in one very distinct patch to one side. 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. Maybe he masturbated in the very cubicle I was now standing in and then left them, ashamed? Or perhaps he never wore them here at all but instead, brought them with him from home, deliberately and brazenly intending to leave them on show!

I carefully removed my own Speedo briefs, revealing a huge blodge of pre-cum, as my tool was released from its temporary chlorinated prison. The goo still clinging to end of my tool remained connected to the blob deposited in my Speedos, as I lowered my trunks carefully and I tried not to make too much mess everywhere, with all the sticky goo falling against my thigh in a long clear string. I do love my pre-cum but it is messy at times; not everyone likes it but I find my own, and someone else’s, a real turn-on. And it makes a fantastic lube!

For some reason, my heart was racing and I felt flushed, as I stepped into my “stolen” pair of camouflage swim-shorts, still with a raging hard-on, all lubed-up and ready for…..well, you know what’s going to happen, I’m sure!
I carefully inserted my erect tool down into the gusset of the shorts and the end of my penis neatly matched the spot where the centre of the stain was, as I pulled the shorts up properly and found that I was almost hyper-ventilating with excitement. My mind was racing through thoughts of what the guy might have looked like. My cute young nephew, a blue-eyed blond, barely 19 years old, had recently paid me a visit and he was just the right build for these shorts. Also, a while back I posted on Billy’s Pervwebsite Forum page, a thread about my having discovered him on a pay-to-view website, doing unmentionable things that any self-respecting uncle should be ashamed and embarrassed to witness! I knew they weren’t his shorts but they would fit him perfectly and thanks to my nephew’s indiscretion, I already knew what he looked like naked on that website, with his soft, peachy buns and his beautiful, erect, 7 inch uncut cock, so my imagination had no difficulty in conjuring-up images of my nephew wearing them and arousing himself in them.

As all these thoughts raced through my mind and the blood vessels at the side of my neck throbbed under the blood-pressure, I stood there massaging myself through the soft material of the shorts and when I looked down, I realized that, exactly where the head of my organ now throbbed and previously hidden by the camouflage pattern of the shorts, was the tell-tale ring of the cum-stain that had once begun in the gusset of the shorts and had obviously leaked all the way through. By this time, a fresh dark mark was appearing, right in the middle of the original stain, as my own pre-cum finally leaked through to the outer material.

It was all too much really. I couldn’t stop it, even if I wanted to; it was inevitable. As I desperately clutched my throbbing, pre-cum-soaked organ through the soft camouflage material, my orgasm began deep inside my groin, and as it spread its wave of intense ecstasy up and around my waist and back down into my groin, my balls jettisoned their load in an agonizing series of pulsating spasms that shot my thick white cream into the white mesh gusset of the shorts and through the camouflage outer material into my own hand. I gasped as I staggered forwards and had to steady myself with one hand against the cubicle wall, as the convulsions threatened to make my legs give way under me.

I finally stood upright, leaning against the cubicle side, wearing cum-soaked shorts and with cum leaking through the fingers of my right hand. I was heaving for breath and my head throbbed; it was the most amazing experience I can remember, at least where no-one else was present in the room at the same time!

I took the shorts home in my bag after cleaning myself up and I was tempted to keep them to wank into again and again. But then I had an idea. I took them back to the pool last Monday and I hung them back on the wall – but at the other end, on a different hook from the one he left them on. When I went swimming again today, they were gone. Were they retrieved by their original owner or discovered by someone else?
