We are a beautiful, obedient girl who remarries and is constantly being raped by an incredibly horny old man (in-law) without her happy mother knows

[Big beautiful girl rape] [Incest] Yui and Mitsuki are sisters with different fathers. My mother was poor, carrying the debts that the man who flew there created, and lived together with the three of us. One day, my mother tells me she's remarried. Although he is an elderly man, he is wealthy and will also be able to take over his debts. Yui and Mitsuki were suspicious, but the smile she saw in her mother's first time in a while was so happy. And a wealthy life like a dream. However, the two were raped every day by their father-in-law, a silly old man, without their mother knowing. They chose to be raped if they could survive if they were both together...
