"Yuna Hinata's lesbian debut." Yuna can't concentrate on her studies because of her private tutor, Nozomi. Enthralled by the seductive Nozomi, Yuna eagerly awaits the punishments she receives from her teacher. "It's the teacher's fault I'm a mess. It's the teacher's fault I get lost in thought. Teacher, please punish me." A series of loving S&M plays unfold: spanking, stomping, and being doused in holy water. Yuna's excitement grows with each special lesson she receives in her private tutoring sessions. And beyond the punishments lies the ultimate lesbian sex, where they yearn for each other.
