School idol Mia is attacked and kidnapped by a reclusive classmate while delivering a print job. Forced to drink tea with strong diuretic effects, she's denied access to the toilet even as her bladder reaches its limit, eventually wetting herself while being filmed. In this state of utter humiliation, she's forced to endure having her nipples sucked, handjob sessions, and relentless deep-throat penetration. Her soaked pussy is licked clean, then pounded deeply and repeatedly, climaxing against her will over and over. Convulsing violently, she screams "No, stop!!" as shame and pleasure gradually consume her. Through this prolonged confinement, Mia slowly descends into depravity, ultimately losing all control.
