Due to the broken air conditioner, Kizaki and his wife called the husband's best friend, who was a scared air conditioner repairman, to come to repair it, unexpectedly the friend arrived at the time when the husband was at work, so he immediately thought of the intention to rape his wife - who he had been watching for a long time. With weak legs and soft hands, the wife could not resist a tall and healthy man, so she could only bite her teeth and endure when she was humiliated. The story didn't end there, she was threatened by him, she didn't dare to tell her husband, this was also the premise for the bastard friend to rape her in the next times. Until one day because the company was out of work, the husband came home earlier than usual, and as soon as he opened the door, he was surprised to see that his best friend was raping his wife, and was about to run back, but suddenly he grabbed a knife nearby and threatened to kill his wife if he took another step. Afraid that his wife would be injured, he helplessly endured the tying up and watched his wife have sex with him in pain and anger.
