A mysterious gloryhole beckons, promising anonymity and pleasure. A curious new initiate, heart pounding, presses her lips to the cool, smooth surface, feeling the pulse of an unseen cock on the other side. She tentatively flicks her tongue, tasting the salty pre-cum, before opening wide, taking the stranger's length into her warm, wet mouth. She learns the art of the blowjob, guided by the grunts and thrusts, gagging slightly as he hits the back of her throat, yet determined to please.
