The hum of the old boiler serves as a rhythm as two maintenance men, hidden in the shadows of the basement, succumb to their carnal needs. The younger one, with a baby face and a monster cock, whimpers as the older one, a bear with a thick, hairy body, devours him. He sucks, slurping and gagging, taking the young cock deep into his beard. The younger one, eager for more, bends over a rusty pipe, offering his tight, hairless hole. The older one, with a grunt, plunges in, fucking him hard, the sound of flesh slapping against flesh echoing in the damp, cold room. They switch, the younger one riding the older one, his cock slapping against the older one's belly, before they both cum, hot and messy, in the filthy, sexy space.
