I read a fic where Grindelwald (as Graves) seduces Dumbledore, who has no idea he's actually Grindelwald. I want one where this happens, then in the middle of sex, Dumbledore accidently calls Grindelgraves "Gellert". On Dumbledore's end, it's an honest slip up. He has no idea "Graves" is Grindelwald, but he's never stopped having feelings for Grindelwald.
Grindelwald, however, hears his real name and figures Dumbledore figured out his disguise. In the afterglow, he removes the disguise and asks Dumbledore how he knew. This doesn't go over very well.
