Rika, a hostess working in Ginza, maintains a close relationship with a married man outside her work. Though their affair is forbidden, being alone together again after a long separation deepens their emotional and physical bond. As soon as they enter the hotel room, their lips meet in passionate, longing kisses. The man gently caresses Rika's breasts and pussy before presenting his hardened cock. She takes it fully into her mouth, carefully licking and sucking. In response, he thrusts his bare cock into her heated vagina, pumping vigorously. Reaching climax repeatedly, Rika receives his thick cum deep inside her as their illicit pleasure intensifies. Lost in instinct and desire, they forget the word "mistress" as their bodies unite fervently, etching this intense relationship into their hearts.
