As a result of an internal survey, a female employee receives a massage. Although she is confused that the treatment will be in the center of her buttocks, her anus is massaged to the point of becoming sensitive, and once her pleasure switch is turned on, she finds it hard to resist even when a penis is inserted. With what little rationality she has left, she holds back her voice and climaxes as the inside of her vagina is massaged. The anal clitoris treatment was performed in a booth with a thin partition set up in a meeting room.
