A tall, slender beauty working as a receptionist at a certain company in the Marunouchi district makes her AV debut. Although she has an elegant, older sister-like aura, her sexual preferences lean towards perversion. She has a desire to be dominated and even enjoys sex with choking, but... once she starts drinking, that perverted side of hers is further unleashed—she loves alcohol but gets drunk easily and becomes horny, just as the words go, becoming increasingly lewd and promiscuous, fully releasing her sexuality!! The lewd older sister turns into a super-lewd sister... A disordered woman is lewd!!
