Ami, a voluptuous married woman with big tits, felt lonely after being repeatedly ignored by her husband, who had no interest in tennis. Wanting his attention, she decided to join a tennis class. Wearing a new outfit and swaying her curvy body, Ami began receiving coaching. However, her pent-up frustration toward her husband caused her body to react intensely to the coach's passionate instruction, growing hotter with each session. During a break, she secretly masturbated alone in the changing room, but was caught by a fellow player. As a result, she ended up being teased and played with using rackets and tennis balls.
