One day, Rena, a new teacher, visited a student in the class in charge of her homeroom teacher. However, as soon as her student welcomes Rena, she makes her drink tea with a coma-inducing drug and lays down. The half-gray student's father who appeared in the middle of the act also intervenes and is thoroughly wrapped around. That night, when the dark money lenders who had lent money to her father came, her father proposed to give Rena's body to her debt form and let her do whatever she wanted. Eventually, Rena becomes a lewd woman who accepts everything from vaginal ejaculation to facial cumshots.
