College student Miyuki visits a small company for a job interview, but it turns out to be a trap set by a group of devils who love creampies. Her personal information is discovered, and she is kidnapped on her way home, imprisoned, and gang-raped. Miyuki is forced to give deep throat blowjobs, is tortured with toys, and is gang-raped repeatedly by vile men, and is used to excrete sperm, with no way to escape. The vile men pour 20 loads of semen into her uterus, training her to enjoy pleasure. She is now a human toilet slave who climaxes with creampies.
