Ruri Mari works at an idol cafe. When she is being sexually harassed by a regular customer, another customer suggests a game. If her genitals react without showing any male characteristics, it's safe! However, if she ejaculates white liquid, she has to provide special service. Unable to refuse, she plays the game. Beforehand, the outcome is obvious, but Ruri Mari is punished with an electric massager, and she ejaculates into her panties in no time. From here, the special service begins. Using the store's box seat, she enjoys 3P! Afterwards, she is thoroughly punished by two men. All kinds of toys are used to torture her clitoris and anus, and finally, a massage gun is inserted into her anus, causing her to convulse and climax repeatedly!
