Friendship or lust, which will win? We conducted a human experiment on Kotoe, a super cute G-cup busty girl from a famous university tennis club, and her friend Ryo! The two of them became dizzy after smoking too much pleasure-oriented shisha. Attracted by the prize money, they recklessly challenged a semen-milking game -- how long can they endure raw sex with their bodies that continue to become more sensitive? Kotoe, a national treasure-class beautiful busty girl, plays with her friend's dick while shaking. When she sucks on the head of his penis, Ryo, who pretended to be cool, also climaxes repeatedly. With a red face and such erotic kisses, there's no choice but to put it deep in her pussy? With sweaty close pistons while smoking shisha, she has an incurable creampie orgasm addiction. It's sex after all!
