Kaoru, who works as a concierge at the hotel, had a reputation among the users for her excellent customer service. A soothing smile, meticulous consideration, and above all, Kaoru valued service that was close to the customer's heart. However, sometimes that overly vigorous service spirit deviates from the scope of work. When he senses that the customer is hungry for the warmth of a woman's body, he offers his own body. In order to make her important customers smile, Kaoru is willing to provide a vaginal shot service.
