Yui Nishikawa makes her premium debut, wrapped in the allure of adulthood! A sister who loves shota invites her close friend, a young boy, for an overnight stay at a hotel. The boy innocently enjoys games and snacks, but in front of a woman's voluptuous body, he becomes fully erect! Following her instructions, he thrusts his hips wildly, and the sister is thoroughly satisfied with the shota's cock. From female anatomy lessons to sleeping together and taking baths… it's a secret "sleepover siscon" sex threesome that Mom doesn't know about!
