Miki learns of her sister's enormous debt and confronts the collectors alone. To save her only sister, she accepts a brutally unfair deal and swears to repay the money as their human sex toy. Overwhelmed by a powerful aphrodisiac, she is repeatedly pounded by thick cocks and drenched head to toe in enough cum to make pregnancy seem inevitable. Even continuing to ride them for her sister is not enough to satisfy the humiliating rules of repayment.
