Bai Jie, the timid wife and teacher, finds her inner slut in the confines of her home. Wearing nothing but stockings and a hungry smile, she takes on her husband Henry in missionary, but her desires run deeper. She invites her students, Su Chang, Xiao Mai, and Zi Zi, to join them, turning the room into a writhing mass of bodies. Bai Jie, big-titted and big-assed, takes each man in turn, from doggystyle to cowgirl, until Henry, cuckolded and humiliated, watches as his wife's lust knows no bounds.
