I probably got about 60% done. Post apocalyptic. The MC's dialogue style: "Covered but her face. Room has tables, chairs. Walk to table. Put down what Geo have brought. Fistful of grass. Hard to find in city. Saw man on old poster, giving to girl. / Smells sweet. Window to right. Whole wall of room gone. Just air, city, below. Geo stares out. Amazed. Frightened."

I guess he is from the wrong side of the tracks and the people on the right side share some rooms in a high rise and they all share a girl who every day is subjected to sex from one of the men. The MC buys a day from one of them.
