Six months into their relationship, Hiroshi visits his girlfriend's home for the first time and is instantly captivated by the stunning beauty and voluptuous figure of her mother. Kind and intelligent, with a subtly sweet fragrance surrounding her, the woman leaves Hiroshi flustered. That night, graciously allowed to stay over, he finds himself unable to sleep. Venturing out of his room, he suddenly encounters her mother in the hallway late at night. "What's wrong, Hiroshi? Can't sleep? Let me give you a little massage," she says softly, leading him into the bedroom. Completely stunned by the unexpected turn of events, Hiroshi can hardly believe what's happening.
