College student Miyuki Arisaka visits a small company for a job interview, only to discover it's actually a trap set by a sadistic group of creampie enthusiasts. With her personal information compromised, she's kidnapped on her way home and becomes the victim of a confinement and gang rape ring. Subjected to relentless rape, toy torture, and continuous creampie after creampie, she's forced to ejaculate sperm helplessly, sinking into despair. The cruel men implant pleasure by filling her womb with creampie after creampie—twenty times in total—breaking her will and conditioning her body. Ultimately transformed into a creampie-slave, she reaches orgasm solely from creampie, fully trained as a flesh urinal.
