Looking for Story

Story by Darklord79

I think it was from AO3. It involved a unremarkable girl who is jealous of her sister and mother for being hot. She summons a Succubus that gives her a hot body and a massive cock. She then fucks and impregates her sister and mother. Epilog goes on that she has a growing harem of pregnant women.

If anyone can find me a copy it would be appreciated. Not sure if it got deleted from AO3 or I forgot to bookmark it.
