In a dimly lit, sterile room, two twinks stand nervously, their bodies bare and smooth. They're here for punishment, a lesson in control and discipline. Their instructor, a stern, older man, barks orders, making them touch, taste, and tease each other. They hesitate at first, but the electric shock from the device attached to their balls spurs them on. They explore each other's bodies, their hands shaking as they stroke hard cocks and caress tight asses. The instructor watches, his own arousal evident. Finally, he commands them to fuck, their bodies moving in sync, their moans filling the room. They cum together, their bodies convulsing as they receive their final, sticky lesson.
