From Worthless To Worthy In Five Mistresses: Episode 3, "Chastity CBT"

Mistress Felony works Scout over hard. The chastity cage bites while she slaps and squeezes his balls raw. Scout strains, breath ragged, but he stays quiet. She shifts fast. Fingers trace the metal cage, teasing his trapped cock till it swells useless against the steel. The tease stops. Her slap drops him back into pain. Each change in mood leaves him shaking, dick throbbing for nothing. She straps on thick black leather and lines up behind him. The dildo sinks deep. Scout grunts, ass stretched open without mercy. Felony pounds steady, hands gripping his hips, driving the point home. When she pulls out, she plants one boot in front of his face. He licks the toe, tongue working the sole until it shines. She turns, presents her ass, and orders him to eat. His tongue buries between her cheeks, desperate and thorough. The dildo gag replaces her strap-on. Scout takes the thick rubber in his mouth while Felony rides it, hips rolling until she comes hard and squirts down his chest. He stays locked, aching, used for every hole she wants. Next trainer?
