Alone, a man teeters on the brink of ecstasy, his throbbing cock in hand. A sultry voice from his phone guides him, a game of "Red Light, Green Light" with a kinky twist. He's to edge, to bring himself to the brink of climax, and then stop, over and over. His moans fill the room, his cock glistening with pre-cum, as he struggles to obey the rules. The countdown to his intense, huge cumshot begins, each second stretching his self-control to its limit.
