Rui Otokoto is a rigid, intimidating female manager whose sharp mind and flawless work leave no room for weakness—but also create enemies without her realizing it. She becomes the target of Kato, an underperforming subordinate, who suddenly brainwashes her at the office with a hypnosis app. Driven by his desires, she is subjected to anal humiliation, while an implanted urge to overcome her supposed narrow-mindedness sends her spiraling into two-hole pleasure, repeated orgasm faces, and total sexual slavery.
