MILK-249 Mei, an office lady on creampie duty, is used daily by old men in a trashy apartment complex

Mei, a neat office lady, moves to a new town and finds herself in an apartment complex full of old men living in filthy rooms. When she complains about the noise, they turn on her and force themselves on her. Trapped in their squalor, she is broken down until she stops resisting and becomes their sex slave.
