Her husband has returned from a business trip after three months. Kana has been waiting for him to return and her frustration is about to explode. When she finds her husband, who has fallen asleep wrapped in a blanket, probably due to fatigue from the long journey, she straddles him and immediately inserts herself! (Huh... it feels better than usual...) Kana is completely satisfied as she repeatedly climaxes with his cock, which is harder than usual, and when she lifts the blanket to kiss him... it's her son! Even if they've mistaken him for someone else, there's no stopping the screw grinding at this point!
