Welcome to the hot-spring inn run by busty H-cup beauty Kanna Kitayama, playing a seductive young innkeeper. She tells her guest that a special “sex hot spring” service is available, but first invites him to watch her masturbate while he decides. Her shameless display makes him so horny that he cannot hold back, and they spend the night fucking raw on the futon. With Kanna offering such irresistible hands-on hospitality, it is impossible to look away.
