Yumi decided to invite instructors to her home for golf, tennis, and yoga lessons while her husband was away on a business trip. The first to arrive was the tennis instructor. Wearing a brand-new tennis outfit, Yumi receives form guidance as the instructor stands behind her, wrapping his arms around her body. Every time she swings the racket, his arms brush against her big tits, gradually turning her on without her even realizing it. With such close physical instruction, Yumi becomes increasingly aroused.
