Study of Virtue 1.5: Slave Maid SM Training (Haruki Genia)

Ibuki, renamed Maya, is a debt-slave virgin subjected to prolonged, sadistic sexual torture by Master Arima and a 'big sister' to break her into an obedient doll. After enduring electric stimulation, aphrodisiacs, forced orgasms, and physical trauma while restrained, Arima presents a sadistic choice: leave as a free woman or stay as his sex-slave maid with her astronomically massive debt forgiven. A shattered Maya ultimately rejects freedom, fully embracing her new identity as the willingly submissive, broken maid Ibuki.
