"Teacher, please punish me." Hana mischievously shows off her chest to the middle-aged cleaning staff. She confesses to the middle-aged teacher and receives his punishment. She is spanked and tied up with hemp rope, but the cleaning staff sees her and threatens her, taking her to his room. "You like being tied up, don't you?" Hana is intoxicated by being tied up. She confesses this to the teacher and receives further punishment... Her still-growing body is drowning in pleasure.
