Incest scenario - the wrong family members
Let's say a girl has come home from her first year in college with a naughty idea in mind. She wants to seduce her father, after having gotten caught up in incest porn during the school year and then watching her roommate fuck her dad. Thing is, every time the girl makes an attempt at catching her father's interest, she instead ends up attracting someone else instead, her brother, uncle, mom, cousin, etc. Eventually she's ended up fucking her way through a long line of her relatives.
I've been kicking this idea around for a little while. How else can I spice it up?
