Unseen hands grope and caress, seeking forbidden pleasure in the confines of the gloryhole. A stiff, throbbing cock pushes through the hole, desperate for touch. A willing participant, hidden on the other side, takes it in their hands, feeling its pulsating heat. They stroke it, tease it, until it's leaking pre-cum, then they plunge it into their wet, waiting mouth, giving it a sloppy, passionate blowjob until it erupts, filling their mouth with hot, salty cum.
