Due to an old family tradition, the Kurisu and Mita families have maintained a master-servant relationship to this day, and as a result, An Mita, the daughter of the Mita family, is fated to serve as a maid. Faithfully adhering to tradition and prepared to offer her body, she becomes a female sex slave who performs sexual services. She is summoned for wake-up blowjobs, and whenever she happens to meet someone in the hallway, she is whimsically ordered to perform servile sex. Her appeal lies in her constant obedience—exposing her skin, offering her tongue, and presenting her pussy. As she pleases multiple men and continues to be desired, her resolve and emotions are revealed. The eldest son of the Kurisu family comes to love her and attempts to save her. His feelings and An's ultimate choice are depicted.
