The long-established inn where Saki serves as the proprietress was once one of the best in the hot spring town. However, now that glory is gone, Saki, pondering her future, consults with Kita, the capable president of a travel agency. Kita comes up with a plan and proposes, "Let's use the beautiful proprietress's amazing body to satisfy the male guests and aim for a 5-star rating and make the inn flourish!" Saki cannot hide her surprise at the plan, but she decides that it is the only way to revive the inn. Saki, who was introduced to a local influential person by Kita, feels that the satisfaction of this customer holds the fate of the inn in her hands, and she struggles to provide erotic service with all her might... "Please heal Kokoro and lower body." This inn is proud of its high-quality hospitality for men. A beautiful young proprietress who serves as a sex bomb to liven up the hot spring inn!!!
