InstitutionX's sex machine whirs to life, its silicone thrusting cock poised to ravage a lucky man's ass. The muscular, moaning stud mounts the machine, lubing up his tight pucker and positioning himself to receive the relentless prostate pounding. The machine's relentless rhythm drives him wild, his moans echoing off the studio walls as it hits his P-spot with unyielding precision. His prostate swells, his cock throbs, and his body tenses as he nears climax. With a final, intense thrust, the machine milks his prostate, triggering a guttural moan and a torrent of cum.
