Kato visits his friend Takao's house to show off his newly purchased DSLR camera. However, Takao's mother, Ayako, suddenly rushes out excitedly. "I won a Hawaiian vacation in a raffle!" she exclaims, thrilled about her first overseas trip. She pulls out an old swimsuit and begins indulging in a tropical resort mood. Seeing this, Kato asks Ayako to be his photo model. In high spirits, she happily agrees, gradually complying with increasingly bold requests. The next day, Kato uses the photos to blackmail Ayako, forcing her into even more daring bikinis and then starting to shave her pubic hair completely bare.
