Rioshi, a woman running a secluded hot spring inn in the countryside alone, decides to do her best to entertain guests when she receives a rare group reservation. However, Rioshi knows nothing about her clients' work, and they become displeased. Trying to cheer them up, an incident occurs: the manager's wallet goes missing. Although Rioshi didn't steal it, the manager is furious and forces Rioshi to perform oral sex on a subordinate, culminating in him ejaculating inside her mouth.

Forced to apologize, her kimono is stripped off, and she is forcibly penetrated. Despite being raped, Rioshi, aroused by various sexual acts inflicted upon her, reaches orgasm multiple times…
