An unfortunate wife is burdened by her husband's debts—Yuri Shiraishi HEYZO-3756

A debt-ridden older brother and sister-in-law tearfully sought help from their younger brother. However, the older brother pushed the family business onto his younger brother, while he himself busied himself with various unprofitable new ventures. The kind-hearted younger brother, unwilling to betray his brother's past, reluctantly lent him one million yen. However, the IOU prepared beforehand by the older brother stipulated: if he couldn't repay, he would have to repay with his sister-in-law's body! The younger brother, having just signed the IOU, began to grope his sister-in-law in front of his husband, engaging in passionate French kisses, thinking that she couldn't repay anyway. The husband could only sit helplessly beside her, letting her lick his nipples, caress his genitals, and then put her fingers in his mouth, even while he was giving her oral sex. Even after being thoroughly aroused and having his face covered in her semen, he was forced to clean her up with his mouth. The hardworking wife's wedding ring lost its luster; she told him that it was all for him. This is a story about a mischievous younger brother, a pitiful husband, and a deeply loving wife.
