Haha no Omanko ni Mosaic o Kakeru Boku ~Okaa-san wa Shakkin Dorei~

"If you can't pay back the money, maybe your wife will pay you with her body?"

Yuuki Kamimura and her mother, Yumiko, were living a modest life in a shabby apartment. Since his father's company went bankrupt, Yumiko earns money by working part-time, and Yuki attends school while working part-time.

His mother is kind, strong, and takes good care of him. Even though they were a little poor, Yuki was satisfied with his life. Until a man named Tatsuya came to visit him.

Nanba, an illegal moneylender, had come to collect his father's debt. In addition to the principal amount of 3 million, Nanba demanded a huge interest rate. Yumiko has no way to repay the debt, so Nanba makes a proposal.

We sell pornographic videos that we can't show in public. How about having your wife act as an adult film star in the video? Yumiko accepts the proposal for the sake of her family. Yuuki is shocked to hear that her mother is a porn star.

Nanba makes a further proposal to Yuuki. Nanba suggests to Yuki that he should edit his mother's pornographic videos.
