Career-oriented office lady Mone Endo is demoted after taking the blame for her superior's mistake, transferred to a special department known as the hospitality relief unit—a division dedicated solely to sexual servicing. There, she is treated merely as an object to satisfy the lust of male coworkers and clients, her body completely dominated. Her 100cm+ I-cup big tits, wide pussy, and even her anus are used in a relentless threesome fuck. Bound tightly with rope, Mone experiences the pleasure of submission, climaxing intensely as both her ass and pussy are penetrated simultaneously in a double-fuck scene. Three thick creampie loads are shot deep inside her holes, further liberating her body and driving her to ultimate ecstasy.
