A curious, eager mouth presses against the gloryhole, ready to receive the unknown pleasure on the other side. A thick, veiny black cock slides through, pulsating with anticipation. The anonymous receiver greedily takes it all in, their wet lips stretching to accommodate the generous length. They bob their head, their tongue swirling around the sensitive tip, tasting the pre-cum that beads at the slit. The cock hardens even more, throbbing with desire, as the skilled mouth works its magic, bringing it closer to release.
