Riri Aimo, a pure and innocent high school track team sprinter, seeks to improve her speed through a radical training program under a perverted coach who introduces her to hormone secretion techniques. Her sincere desire gradually unravels as these extreme methods take hold, driving her toward mental collapse. Tears, snot, gag fluids, and arousal juices pour out uncontrollably. With deep-throat penetration causing vomiting and retching, her consciousness wavers—her eyes lose focus as she enters a drooling, euphoric state.

Witness the shocking transformation of a natural girl completely broken down by relentless indoctrination.
