Responding to a man's request, a big-breasted older sister enters the bath together with him while wearing a school swimsuit. Using her proud 105cm breasts, she gently washes his body with bubbles, causing his cock to steadily grow until it becomes fully erect. She carefully brings him to climax using both her mouth and breasts, then moves with him to the bed. While he dries her hair, she becomes even more aroused as he licks her nipples, then passionately gives him a second climax with loving titty-fuck. A full showcase of her irresistible charm.
