Aya, the educator of new employees, grabbed Seikawa's crotch for being late and gave him a lecture. As punishment, she performed intense oral sex on him. Moriyama had an affair with the female president of a client company inside the office. Seeing this, Aya couldn't help but masturbate in the toilet. When she came out, she encountered Seikawa and was raped in the overnight stay room. She called Moriyama to her home and, in exchange for not reporting his misconduct to their superior, forced him into unprotected sex. The sadistic woman Kanou Aya is irresistible!
