A seven-day ordeal of devastation with a ruthless yakuza; a substitute trains a woman, her body explored in every part; though she doesn't want to climax, she is continuously penetrated to orgasm... Harutani Miu SORA-455

I only learned later that my daughter needed extensive medical treatment due to a rare disease. My husband, feeling guilty for losing his job, hadn't told me about our daughter's condition and tried everything to find a solution on his own. However, he gambled away his money, accumulating huge debts. For my daughter and husband's sake, I chose a week of sex slavery. At the time, I thought it was the right choice. I believed the future could be changed. But when I was being used as a sex object by those debt collectors, even though I hated it, I was helpless. Now, I can no longer face my husband and daughter.
