MIDA-727 I’ll make your beautiful body messy with all kinds of fluids. The busty office lady, locked away in the filthy room next door, is defiled by an abnormal, lustful older man’s relentless advances and degrading treatment… Mitsuki Momota

A salarywoman named Mitsuki goes to complain about the foul smell coming from the filthy apartment next door. But the creepy, overweight man who comes out gets angry and drags her into his dirty room, where he restrains her and gropes her. Overcome with lust, he runs wild and forces himself on her. In the heat of the moment, he pushes himself on her and continues his abusive behavior. Even though she tries to endure it, she reaches her limit and breaks down in humiliation. Seeing her reaction, the man becomes obsessed and says he wants to keep her there, and their forced cohabitation begins. From there, she is subjected to degrading treatment and made to obey his every demand, trapped in a miserable life dominated by the disgusting man.
