My fair-skinned, big-breasted girlfriend was taken away by her father and forced to have sex with him. (DASS-226)

Rinmu, who will graduate next year, and her boyfriend Yuta have kissed, but haven't taken things further. They've agreed to wait until they're adults before having a physical relationship. When Rinmu visits Yuta's house, she meets his father, Tetsu, who treats her with the same gentleness one would show a daughter. That day, due to train disruptions, Rinmu is unable to go home and is forced to stay overnight. The next day, while Yuta is away, Tetsu gives Rinmu an aphrodisiac. Tetsu wants to have a physical relationship with Rinmu, but she refuses. Just then, Tetsu tries to pull Rinmu away, but Yuta arrives and defeats him.
