Hinako, the insurance diplomat, is sexless with her husband. To boost her insurance performance, she indulges in pillow business to relieve her sexual desires. However, Hinako, who is said to be training her body at the gym, has a strong sexual desire and seeks more abnormal stimulation. So, Hinako is bound and restrained, and stimulated to the peak with electric massagers and vibrators. Further, while still bound from behind, she is stimulated from throat-deep fellatio to bound fucking, and finally, she is made to taste semen from a vaginal ejaculation and a tongue ejaculation.
