Bound tightly to the chair, his cock straining against the restraints, he's left alone with his thoughts and the hum of the vibrator pressed against his balls. His punishment for his transgression is clear: he must bring himself to the brink of orgasm, but not allow himself to cum. His body twitches, fighting the urge to thrust into the vibrations, his cock leaking pre-cum in anticipation. The room grows hotter, his breath coming in ragged gasps as he struggles to hold back, his self-control tested to its limit.
