Katrina was a no one at her collage. She was small, a loner, and unattractive in the eyes of everyone there. But one day, a strange thing happened, turning her into the sexiest girl there, and instantly raising her popularity!
That may not have been super descriptive, but it's an idea I want to explore. I was thinking either a genie or something could help her, or she could drink some sort of magical elixer, but the catch would be she would need to have sex and drink the semen of a human to keep her body from reverting back to normal.
This could have practically anything in it with the right tweeks.
Gangbangs, futanaris, monsters, practically anything.
