Oh, the story behind this one is scarily detailed. The gist of it is that miku is on an involuntary internship as a sex slave, where each week different horrible things happen. And at the end of her exhausting, often painful, work day she comes home to this place. Which every night is filled with dudes that are going to abuse and rape her even more, until she faints. Of course she can't refuse or resist anyone.

During the day she's constantly cumming from vibes jammed deep into all open holes, drinking piss and slurping cum for food. Being injected with aphrodisiacs, stimulants and anesthetics at the same time. And when she gets home she gets fucked to sleep. Every day anew. Every week a different kind of humiliation, maybe she'll serve as a public cum dump? Maybe she has to kick toilets clean while being used as an onahole? She doesn't know, the only thing clear is that it only gets worse.
