Pretty much what it says in the title. I'm looking for good harem or polygamy M/F+ stories (and especially ones that didn't get marked as such) that do a good job or showing the group dynamics of such a relationship (without getting too realistic or drama intensive).
Preferably without any mother/son or father/daughter incest.
Bonus points if they have an interesting plot on top.
Some of the stories that I have found and enjoyed are:
It's My Party
Flight of the Code Money
