HND-437 - Paying off my scumbag boyfriend's 10 million yen debt with my body, 100 yen per thrust

My boyfriend blew 10 million yen on debt? Now I'm the collateral. 100 yen per thrust, 50 yen per stroke, and free creampies! To save him, I'm letting strangers use me to pay off the debt. The loan shark's demands get crueler by the day, eventually forcing me to endure a gangbang right in front of my boyfriend. A pathetic tale of a woman selling herself for a total loser.
