Iroha Tanaka, a student teacher at a low-achieving all-boys school, began experiencing extreme stress and shoplifted from a convenience store. Caught by the store manager, she was forced to pay off her debt with her body and brutally raped. The incident was later exposed in a weekly magazine, causing an uproar at the school. Under the supervision of the faculty, her anus was stretched open with fingers, anal beads, and vegetables, relentlessly stimulated until her tight hole became loose. In this state, a cock was thrust inside her, marking the beginning of a new, degrading experience.
