InstitutionX's anal machine specialist takes center stage, transforming a willing male subject into a quivering, cum-drenched puppet. The machine's piston-like thrusts plunge a generous strapon deep into the sub's ass, stimulating his prostate with merciless precision. The sub's cries of ecstasy fill the room as he's edged repeatedly, his body tensing and relaxing in rhythmic agony. The machine's relentless pace and the sub's bound feet heighten the scene's intensity. Prostate orgasms shake the sub's body, and ropes of cum streak his chest, as the machine milks every last drop from his balls, leaving him gasping and spent.
