Ami, a wife, is lonely because her husband, who is crazy about tennis, doesn't pay her much attention. Wanting her husband to pay her some attention, she joins a tennis class. She immediately puts on her new tennis clothes and receives instruction from the coach, shaking her plump body. Her frustrated body reacts to the coach's passionate instruction and becomes hot. Ami indulges in masturbation in the break room, but is seen by her practice buddy, who plays with her body with a ball and a racket.
