A couple who illegally enrolled their child into a prestigious academy with over 70 years of history. Their secret is exposed, forcing them to apologize to the school's chairman. Seizing the wife's vulnerability, the chairman imposes "educational discipline" on her—a humiliating training trip to a hot spring resort. Outdoors, she is controlled with a remote vibrator; in the bath, she is forced into mixed bathing and made to perform fellatio. Amidst groping of her nipples and ass, she exchanges deep, saliva-filled kisses. Eventually, the chairman's penis penetrates her twitching pussy.
