In the dimly-lit gloryhole, a black cock thrusts through, eager for action. A hungry, anonymous mouth envelops it, slobbering and sucking with wild abandon. The cock grows harder, pre-cum dripping as the stranger on the other side jerks it off. The pace quickens, balls tighten, and a hot, thick load of cum shoots out, coating the insatiable mouth. The game repeats, with another eager participant ready to service the black cock.
