In a dimly lit dungeon, a powerful femdom teases her bisexual sub to the brink of madness. She parades her curves, clad in leather, her massive strap-on bobbing tantalizingly. The sub, locked in a chastity device, groans in despair as she strokes her toy, taunting him with its size. She forces him to lick her boots, grinding her crotch in his face, before finally releasing his cock from its cage, only to deny him orgasm again and again, pushing him deeper into his bi-sexual fantasies of humiliation and denial.
