Twenty minutes by bus from the nearest station, in a block of flats where most residents are middle-aged men. Haruka lives in one of those flats, taking pocket money from the other residents in exchange for her body, supporting a father who gave up on working before she can remember. To her this isn't misery or misfortune — it's simply how the days go. The men in a building with no women in it want something maternal, and pay her cheaply to borrow her tits and her pussy. She gives them handjobs every day while they suck her nipples, and doesn't care that her areolae have gone red. A room has just come free. Vulgar and unpleasant, but very good news for a cock — any interest in life in this building?
