The gloryhole's black cock is a temptation too great to resist. A eager mouth presses against the partition, tongue flicking out to taste the smooth skin of the massive black shaft. The cock stiffens at the touch, and the sucking begins, hungry and voracious. The unknown sucker takes it deep, their lips stretching to accommodate the thickness, their tongue swirling around the sensitive tip, drawing out moans from the other side of the wall.
