I bought a portable steam room for various reasons, and I used it for the first time last night. I set it up on the balcony of my apartment, and I waited until it got dark. I figured I should have a proper steam, naked, so that's what I did. Sitting in the dark, by myself, a little bit high, hot, and sweaty, I couldn't stop myself. Feeling the steam warm my cock and balls, and feeling the heat on my bare cock head, I was overwhelmingly horny, I had to start touching myself.
First, some nipple rubbing, that felt incredible and took no time to get my cock hard and throbbing. Then the thought of how wrong it was to great getting myself all riled up like this took over, and I had to touch my rock hard raging boner. God, I don't remember the last time it felt so huge and solid in my hand. And to have my balls hanging so low from the heat and swinging while I jerked my cock and played with my nipples in turn, it was nearly impossible to stop myself from cumming. Then, the memory of an erotic story came into my mind, and I had no choice in the matter, I had to keep jerking, my cock was soaking wet from the steam, and I was leaking so much precum, I thought it would be any second before I exploded my load all onto the wall of the steam room, it turned me on so much that I had to take some precum and rub my nipples with it. That got my cock as hard as diamonds, and during a couple throbs, the precum shot out of my cock.
There was precum everywhere, on my nipples, on the floor, on my cock head, running down my shaft and balls, it was incredibly sexy. Luckily, the steam ran out before I could unload out on the balcony.
I went inside, took a couple pictures to post here, had a cool down shower, and went to bed to finish myself off. I had such an amazing long orgasm, and I unloaded so much cum, so hard that I fired some onto my pillow.

I can't wait to have another steam.
