Lesbian Aunt Marriage Pregnant Fantasies?

[PSZer0Dark30]

Okay. This is a bit of a tough one... maybe. I'm looking for a story that involves lesbian sex with a girl and her aunt. If I"m not mistaken, the aunt ends up seducing the girl slowly over time. Eventually though, the girl becomes very dominant in the relationship. I don't remember too much but I know there is talk about marriage eventually and there's a scene where the girl is fucking her aunt with a strap-on and starts dirty talking about getting her pregnant.

Ring any bells for anyone? I know it was both on Lit and on ASSTR. Any help would be greatly appreciated.
