Instead of my parents going on a trip, my mother's best friend, Maina, will take care of me. Ryosuke can't help but have erotic fantasies about Maina's sweet scent. He wants to touch her smooth, pure white skin, and bury himself in her soft-looking breasts. Ryosuke, who is preoccupied with Maina, plots to make fun of her freshly-removed, fluffy underwear, but ends up discovering that he stole her.
