"No...it's deep...I'm already deep inside just by inserting it...I'm cumming!"--Nephew Natsuki, who will work as an intern at her husband's company. Minami, her wife, was worried about living with a man, even though he was her nephew, but she believed her husband's words, ``He's a good young man,'' and decided to live with him. On the night of a small welcome party for her, Minami, who was taking care of her drunken husband, also gets so drunk that he falls asleep on the sofa in the living room. At that moment, her lewd fingertips approach her flushed body... "Are you? Natsuki-kun will wake up..." she refuses, but she is excited by the scent of a man she hasn't seen in a long time and entrusts her body to him. But there's something strange about that guy... he's so big and strong... Minami feels intensely as her cock thrusts into her vagina to the point that her waist lifts. "Wait...this is too intense! Maybe it's not my husband who's inserting it right now...!?" Even though it's no good... even though it's no good... I can't resist this pleasure anymore!
