Yoko is a divorced mother who raises her beloved daughter Rena on her own. One day, when she finished her shopping and came home, she heard a suspicious gasping voice from her daughter's room. She was going to preach that she didn't do it in the daytime, but surprisingly, her partner was Kyojiro, a sex friend. Yoko is flustered, but the fact that she has touched not only herself, but also her daughter, she says with a bewitching smile, "Can't you be satisfied with just me?" Kyojiro is puzzled by the sudden turn of events, but he makes up his mind that it is a shame for a man not to eat.
