Set in an era defined by a rigid class system, this story unfolds within a society where the bourgeois class commonly kept domestic servants as sexual slaves. Yuki, a young country girl who recently arrived in the city, begins working as a live-in maid for the prestigious Ichijo baronial family. Overwhelmed by endless chores and deprived of sleep, her life quickly spirals into abuse and domination as the men of the household begin dragging her into their rooms. She is forced to worship their feet, her plump, shapely buttocks lashed with a whip, and subjected to deep-throat servicing as a daily routine. Eventually, her anus is violated and she undergoes enema training, until her entire body is completely under the control of the baronial family.
