The black cock pulses, hungry for release, as the anonymous mouth works its magic. The licks, sucks, and deep-throating continue, the cock disappearing entirely, only to reappear glistening and engorged. The mouth works diligently, bringing the cock to the brink of explosion, before backing off, teasingly, and starting the process anew. The rhythm is intense, the pleasure palpable, as the cock is relentlessly blown in the dark confines of the gloryhole.
