G-cup, demure bank employee Sayaka stars in this installment of SEX Finance, playing a woman who gives her entire salary to a host. Her stable job, stunning beauty, and gorgeous figure are her main appeal. She requests a loan of 1 million yen, hoping that the longer she remains in debt, the longer the relationship will last. Initially hesitant toward filming, she quickly starts squirting once given sex toys. Despite her innocent appearance, her dominant, sadistic nature gradually emerges as the session progresses.
Under the Mating Finance rules, borrowers must provide sex videos as collateral, with all footage completely erased upon full repayment. Loan amounts are determined by the borrower's looks and body, and failure to repay risks the video being leaked. Satisfying the lender may increase the loan amount, while referring new clients brings favorable interest rates. The service also arranges short-term overseas jobs.
The first part features breast fondling, ass kneading, nipple play, nipple licking, fingering, cunnilingus, handjob, squirting, vibrator insertion, kissing, blowjob, standing doggy-style penetration, cowgirl position, and creampie in missionary. The second part includes playful bathing together, double blowjob, cumshot on tongue, and internal cumshot. The third part involves dressing her in cosplay, followed by bed play including kissing, blowjob, 69 position, oil pouring, cowgirl penetration, immediate penetration, doggy, lying doggy, creampie in missionary, and facial cumshot—delivering increasingly intense and intimate scenes.
