You guys are well aware of how much Speedo fun I’ve gotten up to in pool change rooms over the years. It’s a huge part of my Speedo fetish. Well, I’m here to share an experience I had in the change rooms yesterday. Let’s just say I’m still a little sore from the encounter. The Big Guy and I are both in our thirties and this experience was consensual.

It was a beautiful winter’s day—so much so that I put sunscreen on—and my Speedo tan would have gotten a top-up after spending nearly an hour swimming laps. The pool was quiet enough that I had a lane to myself. I dropped my dork shorts, stripping down to my newish Tom Daley ADIDAS Speedos, which are incredibly sexy. I probably could have gone one size bigger, but as they are, they’re a nice, snug fit.

There were two empty lanes beside each other in the middle of the pool. As I went to jump into one, I looked up and saw a guy at the opposite end of the fifty-metre pool about to jump into the same lane. He saw me just as I saw him, and we played a bit of musical chairs as we both moved over to the other open lane. We got it sorted in the end and were both laughing.

When I’m in the pool, I don’t mess around. Once I’m in, I bang it out. I swam fifteen hundred metres. I regularly swap which side I breathe on, so every two hundred and fifty metres, I’d catch glimpses of the guy in the lane next to me as we passed each other. He was a big guy—leaner than me, but at least half a foot taller—and he swam a lot faster than I did. He was wearing a pair of navy Speedos with some white writing on the bum that I couldn’t quite make out.

After my first set, I swam five hundred metres of slow breaststroke, alternating with a length on my back, kicking. This gave me a chance to look around the pool, and it was even quieter than when I’d gotten in. The Big Guy was loitering a little at one end, but apart from a nod of the head, we didn’t chat.

Another five hundred metres of freestyle, and I was done.

I jumped out of the pool and, since I had some chores to do on my way home, headed to the change rooms for a quick shower and a change into some dry Speedos. I wear Speedos all the time.

The huge change rooms were empty. I had a quick shower, put on a pair of ADDICTED Speedos, and was just packing up my bag when I heard someone enter the change rooms. It was the Big Guy.

He dropped his bag against the wall on the opposite side of the change rooms from where I was. As I turned to leave, we crossed paths while he was heading towards the showers. He was a big man. My guess that he was half a foot taller than me was spot-on. He had broad shoulders and looked to be in his mid-to-late thirties.

He had his towel over his shoulder and was standing there in all his Speedo glory. His navy Speedos had the logo of the local Surf Life Saving Club on them. From my quick, discreet glance at the front of his Speedos, I could tell he was a big man all over.

As we navigated past each other, we joked that we’d been getting in each other’s way all day, referring to the lane confusion earlier.

Then he said to me, “Love your Tom Daley Speedos.”

Wow. That threw me off. This guy knew his Speedos.

I kind of stuttered my response. “I like yours too.”

There was nothing about this guy that gave me the impression he was gay or bi. He looked like a straight Aussie bloke. But he knew his Speedos.

As he walked towards the shower cubicles, he looked over his shoulder at me and said, “Real men wear Speedos, right?”

He gave the slightest flick of his head towards the shower cubicle at the end, which he was heading towards.

Was that an invitation?

While I stood there, my mind racing, he opened the shower cubicle door and turned back towards me. This time, his little head-nod invitation was delivered while he grabbed a handful of his crotch through the front of his Speedos.

That was definitely an invitation!

He closed the door behind him, and I stood there like a kangaroo caught in headlights.

A moment later, I put my bag back down, put on my wet ADIDAS Speedos, and grabbed two condoms, which I always keep in my bag for just this sort of occasion. I tucked them into the hip of my Speedos, grabbed a towel, and headed towards the cubicle at the end. The door had been left slightly ajar, and the shower was running.

I knocked lightly.

“Cum in,” was the reply.

Opening the door, I was greeted by the sight of the Big Guy with his back against the wall and water splashing down his front. The front of his Speedos was pulled down, revealing his cock and balls, while his big hand stroked his big cock.
