A Russian amateur, locked in a chastity device, is brought to his Mistress for a brutal lesson in obedience. She climbs atop his face, her pussy dripping with desire, smothering him as she demands his tongue's service. His balls, confined and aching, are her plaything, bitten and slapped until they're sore and swollen. The sub's cuckold predicament intensifies as his Mistress' pleasure grows, leaving him breathless and yearning for release, yet denied by the unforgiving cage.
