There is a man with a loving wife and daughter. The man suspects that his daughter is trying to seduce him, and his wife catches on to this and encourages the relationship but the father is hesitant because of his own personal beliefs that incest is wrong. Meanwhile, the daughter's friend, who is named Ruby (the only name that I can remember) begins having sex with the man and Ruby's mother also enters into it. The man's wife knows about all of this and participates in it as well, but the man refuses to have sex with the daughter in the beginning. I've been looking for this story for a while, and any help is greatly appreciated.
