Working as a private tutor supporting a high school girl's studies, Yuria hides a dark secret beneath her innocent appearance—she is a deviant choking lesbian obsessed with asphyxiation. Living secretly with her student Risa, Yuria suddenly shocks her with a confession of desire, drawing Risa into her twisted world. Using choking and suffocation techniques, Yuria renders Risa unconscious, reducing her to a helpless state. With black gloves and plastic bags, she employs various methods to steal Risa's consciousness, completely dominating her. Risa's eyes roll back, drool and foam spill from her mouth as she collapses into a pitiful condition. Yuria delights in the sight, molesting Risa's limp, unresponsive body. Overwhelmed by pain and pleasure, Risa's mind is utterly broken. This work delivers a shocking exploration of lesbian extremes, pushing past the boundaries of body and mind.
