I'm really sorry if you're upset by this its crude this was a missing long-term lesbian fan fiction for smut it was mostly smut and super sexy.
A girl who met her true love and stopped her casual sex ways but it was explicit.
The main character is someone who has a ton of casual relationships but never takes love seriously here are parts of the description.
"She loved having sex especially sex with gorgeous women"
'That is until she met..." Love everlasting of her life
And then the first line in the book
"Under the counter it was her first time tribbing judging by how she couldn't catch her breath"
it was so hot
It was an original fanfiction on ao3 and seems to be deleted
