In this adult student role-play, one male club member makes a calculated move that reverses their positions. Trapped in a drugged sexual ordeal and pushed to her limits physically and mentally, Natsume is reduced to screaming orgasms and forced obedience, ending with her humiliating apology displayed around the school.
