A couple hoping for their son's academic advancement set their sights on a special enrollment slot at Sugi○ Academy and attempt to build a relationship with the school's chairman. However, there is only one such slot available, so the couple plans a trip to host the chairman. During the trip, the chairman repeatedly performs lewd acts—touching his crotch, buttocks, and nipples—right in front of the husband, who remains oblivious. The wife continues to endure various forms of training, including remote-controlled vibrator sessions at tourist spots, mixed bathing, and intense kissing. Ultimately, the chairman reaches an extremely obscene conclusion by taking the married woman from behind and forcing the husband to open the door while still inside her.
