Our chaste sissy slave is in for a relentless session with the fucking machine. His big cock aches, but he's denied release as the milky machine pounds his prostate. The relentless thrusts make him buck and squirm, but he's bound tight. His femdom trainer watches, cruelly edging him closer to the brink, only to deny him the sweet release of orgasm. His milky prostate takes a pounding, with every thrust making him whimper and beg for mercy.
