Sato Yukachan's first outdoor shoot is a risky one where she has to have sex unnoticed in a public place with ordinary people around! In an office that unknowingly cooperates with the AV shoot, separated by just a thin wall, they engage in sex. Under the table of a izakaya, she experiences an orgasm with a vibrator, and in the toilet, she performs a breast job! At a home party of a staff acquaintance, she quietly endures the sounds while having sex! Whimpering softly, she reaches a silent, intense climax!
