Under the guise of a seminar retreat, a professor invites young researcher Nozomi Anzaki to his home. His true intention: to turn her into his sex slave. Having lost his wife long ago, the professor becomes obsessively fixated on Nozomi, who resembles her, and plots to make her his possession. Through brainwashing and rigorous training, he dominates her mind and body. The desires of a middle-aged man gradually invade the slender, innocent young woman. She receives creampie after creampie, tortured by sex toys, climaxing repeatedly. Extreme oral training and sexual play escalate relentlessly, pushing Nozomi to her limits. What will become of her, her face drenched in the stench of semen?
