Ayumi Shinoda transforms into a strict disciplinarian mother the moment she puts on her glasses. Furious over her son's poor grades, she unleashes her anger and begins a sexual education using her body. She erotically explains each part of her mature body, training both concentration and cock with lotion handjobs. She dominates a teacher lecturing about education with face riding and enjoys reverse education with pantyhose and footjobs. Blaming her husband's genes for her son's bad grades, she makes her obedient husband squirm with cunnilingus and spanking, then rides him in a wide-legged cowgirl position, embodying the harsh, cock-focused sexual discipline of a strict mommy.
