Unpopular office worker Miko Sakura stays behind alone to work overtime. Used to masturbating every day, she cannot resist slipping off her glasses and touching herself at her desk, unaware that a male coworker has appeared behind her. Seeing her without glasses for the first time, he loses control, grabs her breasts, and buries his face between her legs. The rough attention after a long dry spell unleashes her pent-up desire: she screams through the empty office, thrusts her hips wildly, talks dirty, and cums over and over.
