He shot his load on to the fogged glass shower divider separating our two showers.
I had left the steam room, delirious from the heat, from trying to sweat out everything bad in my body, had stumbled to a shower stall. I could hear someone else leaving the steam room behind me, and then saw that they, despite other open showers, had opted to go in the one next to mine. I knew what was coming.
For a straight gym, my gym has some of the most homoerotic gym showers I have ever been in. The shower stalls have fogged glass separating one from the other, so that you see the outline of the person showering next to you, see a blurry vision of a naked male next to you, one of those scrambled porn channels that you would try to unscramble mentally as a kid. I usually peek out of the side of my eyes, so as to be somewhat discreet, as I watch guys shower next to me.
There was the usual coyness of the two of us washing our cocks and our assholes for way too long, some way of saying that we were cruising. He would put his ass closer to the glass separating us. For a moment, the scrambled cable station, comes into view. For a second, I see a late night softcore movie, the volume turned down so my family doesn't know what I'm doing, trying my best to mentally hold on to the image, to save it for later, to eventually have enough of these snapshots to assemble into a short movie, one that will be projected on to the screen of my childhood sexual imagination in moments in locked bathrooms.
He turns around. I get a good view of him stroking his cock. I stand closer then, giving him a view of me near the glass, me stroking my cock.
I watch underneath the glass, the view of his sexy toes digging tighter and tighter into the floor tiles as he gets nearer and nearer orgasm. It's about to come. He puts the head of his cock against the glass and I watch with all the hunger in the world as his semen paints the glass between us. He towels off and leaves the stall, not bothering to clean this huge streak of cum from the wall, not bothering to rinse down the drain the drops of it on the floor. For a moment, I dream of how good it would feel, how good it would taste, to wipe up the drops on the floor and put them to my mouth, my tongue. I wish I could reach the streak of it on the glass between us. He has left to get dressed and I watch his cum slowly ooze down the glass in slow motion and am so turned on by this, by this now absent man, by his swagger, by his lack of care. Something in his failing to clean up his cum, to leave it there for whoever to see, his exhibitionist qualities, push me over the edge. I cum. I wash mine down the drain and watch his on that glass keep sliding down as someone else steps into that stall.
