After finding out about her pregnancy, Shouko and her Husband have decided that it would be worth taking what might be their last leisurely vacation together before the birth at a hot springs for their anniversary. It just so happens that they run into Ichiro, well within his expectations of course, who wishes them the best for the pregnancy, and offers the two a "special couple therapy session" as a gift. With Shouko already well trained under his hypnotism, the only challenge might be her unsuspecting husband.
Back where it all began, Ichiro pays the unsatisfied housewife Shoko another visit. Upon spotting her Shoko's old high school uniform, he gets a fun idea. Using hypnosis to regress her mind back when she was sixteen, he makes her forget about her husband, and convinces her to give him her "virginity", as well as to bear his child.
Shoko is once more the target of self-proclaimed hypnotherapist Tsuzuki as she is subject to even more risqué sexual training. From the use of dildos to nipple clips, Shoko’s body slowly grows accustomed to her new-found sexual pleasure to the point that sex with her own husband has started to grow stale.
Hypnotherapist Tsuzuki sets his sights on a student member of the school swim club, Airi, as he conditions her to subconsciously seek sexual gratification from the predating pseudo-therapist. Apparently, the effects of hypnosis are more pronounced in girls undergoing puberty, but despite all of the sexual intercourse she’s had with him, all she imagines is her pleasuring herself. Just what is there that Tsuzuki CAN’T do with his uncanny abilities?
Meet Ichiro, the hypno therapist, whose set up shop close to a small cafe that Yuiko Ishida works in. He gives her a free session in exchange for a womans opinion on his office, and she got much more help with her marriage than she was expecting.
Setsu Ayase was taken in to the Asano household after she was orphaned, where she became the reluctant mistress of Keiji Asano’s father. When his father died, Keiji forcibly extracted Ayase from his parent’s household after a period of domestic violence perpetrated by Keiji’s own mother. Coming from a history of such abuse, can either of them ever live a normal life together?
