The complete in-motion OVA adaptation of Harushiro Shusuke's Take Me as Much as You Want in Place of My Daughter from TI Net. This adult family role-play follows Minako, whose daughter Reina is pregnant. Reina's husband Akio is a large, polite, cheerful former rugby player with a charming smile. While Reina is out, Minako looks through old clothes and tries on a revealing cheerleader uniform. Mistaking her for Reina, Akio embraces her from behind and tries to initiate sex. He stops as soon as he realizes she is his mother-in-law, then admits he has gone more than a month without sex and is close to his limit. Minako responds by offering to take her daughter's place and receive all the semen he has saved up. As their affair continues, her motherly feelings give way to raw sexual desire, and she wonders whether she can ever return to being a proper mother.
