Queen Actress Tukishima Naru dominates her submissive cross-dresser (Naru) by turning him into a human toilet. She starts by making him smell his own feces through his nose. Kneeling on all fours, Naru presents a huge dildo to Mistress Tukishima, who skillfully guides it into his anus with her tongue. As she pleasures herself with the dildo, Naru must clean it using only his mouth and saliva. Once he's made it shiny enough, he receives a reward in the form of a passionate anal ride on top of Mistress Tukishima's plump ass. Not only does she indulge in some scat play but also offers up her own urine as part of their intimate session. The climax comes when Mistress Tukishima decides that it's time for full-on toilet training. She forces poor Naru to hold in his bowels until they're about to burst, then administers an enema to help relieve the pressure. Afterward, she presents him with a cute pink diaper which he wears while becoming increasingly aroused due to his desperate need to defecate. Finally, after enduring countless humiliations at the hands of his mistress, Naru is allowed to release his pent-up waste onto the floor – covered head-to-toe in filth from his ordeal. In this final stage of training, Mistress Tukishima feeds Naru food she has previously chewed before spitting out what remains undigested back into his mouth. Next come various items like carrots, sausages, and gummy bears which are inserted into his rectum and forced down his throat. To wash everything down, she pours holy water over his face and neck before presenting him with an unbelievable amount of excrement - more than he could possibly handle! Despite being completely overwhelmed by both quantity and disgusting taste, Naru continues to consume every last drop under orders from his sadistic queen actress mistress.
