At a welcoming party for new employees held at an izakaya, the stunningly cute new hire Rei Kuruki becomes the center of attention. The male coworkers who obsess over her draw resentment from the female seniors, who then turn their focus on Rei and begin tormenting her with pranks. The harassment escalates with scenes of her being forced to touch penises while completely naked, and penalty games that expose her breasts in public within the restaurant. The atmosphere of the welcome party spirals out of control, culminating in her being taken away by car, where everyone participates in bareback gangbang sex. The female seniors, smirking all the while, join in the abuse as Rei is repeatedly creampie fucked over and over again. A twisted new dynamic emerges, and the intensity shows no sign of stopping.
