“Shit!” Carl yelled, and I hoped no one was walking by the room to hear what we were doing.
This was going to be quick. Back and forth we went, grunting and swearing, while Carl took a hand off the wall to pump his cock dry. I found his sweet spot and he howled, spurting all over the wall before him.
I was close behind, filling the condom with a “goddamnit!” as I found release. The two of us collapsed together against the wall, breathing heavily, my head on Carl’s shoulder.
“You’re h-heavy,” he groused.
“Sorry.” I forced my sated body to move away from his, holding onto the edge of the rubber so it wouldn’t get left behind in his ass.
Carl walked around the room and found a roll of toilet paper. We both cleaned up, washing our hands in the sink used to refill cleaning solutions. I wrapped up the condom and stuck it in my pocket. No need for any of the cleaning staff to know what had occurred, though I was sure it happened often enough.
