Ai, a young lady raised in a wealthy family, begins dating a man named Ashida whom she met on social media. However, he is a delinquent working for a company under the control of a yakuza syndicate, and he has been deceiving Ai to extort money from her. Pure-hearted Ai doesn't notice this and, at his request to "do a part-time job," heads to a certain location. Waiting there for her are thugs running an underground brothel. Passed around by Ashida's colleagues... she is thoroughly treated as a plaything, subjected to massive creampies that make pregnancy inevitable, and facial cumshots that leave her beautiful face covered in semen...!
