In the dimly lit, pulsating heart of the gloryhole, a black cock, thick and veined, awaits its anonymous sucker. A horny patron, unseen, reaches through the partition, eager fingers wrapping around the shaft. The cock stiffens, ready for the wet, warm embrace of the gloryhole's secret devotee. The licking begins, tentative at first, then hungry, as the anonymous tongue explores every inch of the rigid, black flesh. The cock slides in and out of the opening, fucking the willing mouth, as the sucker's hand works its own throbbing member. The rhythm intensifies, the licking turning into sucking, deep and intense, until the black cock explodes, filling the gloryhole with hot, sticky cum.
