But her husband was deceived by his guarantor and ended up with a huge debt, which caused him to break down and be hospitalized. Nana was driven to the brink by debt collectors when her husband's brother appeared before her. He offered to help her, using Nana's body as collateral. At first, it was just to repay the debt... But Nana was penetrated again and again by her brother-in-law's powerful cock and fell into a hell of pleasure! Brother-in-law, please forgive me.
