The first person is Sena, a married woman who at first glance gives off an uptight image in a suit. But in reality, she's sexually frustrated and her panties are already soaked. The moment she grabs a young man and lets him into her room, she changes completely and becomes a nymphomaniac at the front door... The second person is Ryoko, a wife who also gives off an impression of being serious, but once the lid is opened, she sucks and strokes the young man's immature genitals, begging for sex!
