A self-employed couple, exhausted by life and work, with a failing sex life.
They visit a psychosomatic clinic, but it turns out to be a horrific place where a corrupt doctor named Ozawa awaits them, performing lewd brainwashing and sex training under the guise of treatment.
Through his malicious practice that digs into the gaps of their hearts, the couple is brainwashed and trained together.
The wife, Miki, gradually becomes a slut... She begins to crave Doctor Ozawa's thick cock, taking it deep into her throat.
Ignoring her husband, who is shocked after spying on her, she next performs M-shaped leg-spread dildo masturbation followed by a blowjob right in front of Doctor Ozawa.
To the protesting husband, Ozawa coldly declares,
"Miki-san is starting to awaken to real sex. It's about time you woke up too!
Now, the two of you have sex right there—real sex!"
Contrary to the husband, who is happy thinking everything is going well, Miki still cannot forget Doctor Ozawa's thick cock...
"This isn't a consultation, but how about dinner at my place next week to celebrate your recovery?" Invited by Doctor Ozawa, the couple visits his home, where the husband finally learns Miki's true feelings.
"Miki-san, please choose. If you choose me, you will live as my sex slave for the rest of your life. Now, which will it be?"
"Doctor, please make me your sex slave."
The two engage in intense slave sex right in front of the husband.
Miki reaches the peak of ecstasy with Doctor Ozawa's thick cock...
