In a dimly lit room, a man's body is a canvas for electric exploration. A small device sends pulsating waves through his flesh, awakening nerves and drawing pre-cum from his throbbing cock. He writhes, gasping, as the toy's power increases, edging him closer to a no-hands climax. Finally, with a guttural groan, he's pushed over the brink, his big cock twitching as it releases hot, sticky cum, leaving him spent and trembling.
