A woman is taken to a host club by a friend for the first time. She is confused by the unfamiliar place and the host's service, but when they are Kokoro, she gradually opens up and feels comfortable. "The truth is, this is what's going on." She is surprised when the host shows her his erect penis inside the club, but she is gradually Kokoro by his eloquent speech and by the penis she hasn't seen in a long time. Once she gets turned on, she changes completely and devours the penis inside and outside the club.
