On the top of my head, maybe "power to the players" from monkeyxmonkey on GLG could be ghetto, I don't remember, maybe more middle class and it is high school background.
Second is about a 18 or 19 year old runaway who collapses on the front porch of a mid-thirties businesswoman who is in the closet.
third is about a 19 year old pizza delivery girl who falls for one of her customers who is a rich bored late twenties house wife.
second and third are milfs and the stories are on fictionpress, don't remember the names currently, but could look later.
