Ai Ohtori, a sadistic teacher, delights in breaking in her young, pure students to the world of BDSM. She uses bondage to keep them helpless and vulnerable, her skilled hands and toys coaxing screams of pleasure-pain from their lips. She focuses on one student, her ripe body trembling as Ai explores her every secret place. The girl's virginity is no match for Ai's expertise, and she's soon begging for more, her cunt dripping with need. Ai grants her pupil's wish, fucking her hard and deep, marking her as her own with a torrent of cum.
