We have a unisex sauna at my gym. I usually go in there after I hit the pool, usually it’s very uneventful. But today was different.

After my swim I headed to the sauna. It was quiet in there and there was just me and one other guy but he left shortly after I arrived.

I was in my own head thinking about things and then this beautiful woman walked in. She had a bikini on, and while it wasn’t the smallest in the world, it left nothing to the imagination.

She was sat on the lower level so I had a good view down her top and of her toned body.

I could feel myself getting hard so I tried to take my mind off it, but it didn’t work. Before I knew it my cock was firm and my tight trunks were straining to hold it.

I tried to act as if nothing had happened but I could tell that she had noticed given it was basically at her eye level.

We didn’t say anything, and I didn’t want to leave and expose myself further so I waited it out until she left, which felt like an eternity.
