A male cleaner

He looked into the slightly puzzled face of a cleaner. He was a latino in his early fourties, he'd say, a bit on the stocky side but with broad shoulders and the built of somebody used to physical work.

Also he had his pants open and a medium sized but rather girthy dick out and stroking it with one of his big hands.

"Ah, Dios mio! Sorry Jefe, I did not see the stall being taken."

He still held his Dick in hand and nodded towards the whole.

"Just taking my break. Go on Vato, give the Zorra your load, I'll wait." He grinned. "She is great, no?"
