The compressor hums softly in the background, a steady rhythm that matches the pace of the unseen hand working a thick, throbbing cock.

The man's grunts grow louder, more insistent, as he chases his climax, eventually finding it, his body tensing as he erupts, ropes of hot, sticky cum coating his hand and the floor.
