Kaori Saotome's third exclusive release from One's Factory marks her first anal-themed title. Despite having no prior experience with anal sex in her personal life, Kaori undergoes extensive preparation for her first anal penetration, including repeated enemas, cotton swab insertions, and sausage insertion to gradually stretch and loosen her anus. Her face alternates between surprise and pleasure as she experiences these new sensations for the first time. Fueled by unrelenting curiosity, she moves on to a sandwich fuck, completely immersed in uncharted pleasure, screaming passionately as she forgets all pain.
