Nana, a voluptuous big-titted girl, starts working part-time at a local izakaya and gets hired. One day, she's called in by the manager under the guise of training, where sexual harassment begins. Gentle and obedient by nature, Nana struggles to resist the escalating harassment and eventually gets fucked raw. Watching employees force her into titty fucks and handjobs, she's further dominated. The next day, she's taken to the manager's house again under false pretenses, where three coworkers join in on the harassment. Though hesitant at first, shy Nana gradually surrenders her body and awakens to pleasure. As the manager's huge cock thrusts violently inside her, Nana repeatedly makes lewd faces, turning herself into a spectacle for all to enjoy.
