An incestuous sex movie by Miu Shiromine. After getting married, Mari found out that her husband had ten half-siblings. Her father-in-law was a womanizer. Her father-in-law agreed to pay the down payment on the condition that Mari and her husband let him live with them. After living together for half a year, Mari felt extremely disgusted with this father-in-law who changed women like he changed clothes. But she never expected that, instead of going out to find women, he would even target her, wanting to impregnate his daughter-in-law!
