OKSN-013 - Everything about Mom, Tamaki Yasuoka

She was already a bad actress to begin with, but the 'idiot son' character's acting was even worse and totally ruined it for me. After getting sexually harassed by the doctor during a check-up, she suddenly ends up having sex with him, and then the son starts massaging her shoulders, only for her breasts to be tied up with rope and the scene to jump straight into full nudity—there's absolutely no sense of story here. I wish they'd put more effort into making it actually exciting.
