A busty older sister, dressed in a school swimsuit at the request of a man, joins him in the bath. With her proud 105cm・I-cup breasts, she lathers his body with bubbles, and despite her efforts, his penis remains firm! Using her breasts and mouth, she gently teases him before moving to the bed. While the man dries her hair, she enjoys having her nipples licked, and then, with loving paizuri, she prompts his second ejaculation.
