Newt goes undercover and uses a potion to temporarily change himself into a woman. He crosses paths with Graves (accidentally or they are already working together- your choice), and can hardly hide his arousal, even though he obviously never had sex as a girl before. Graves, being a gentlemen, is obliged to help.
Bonus points if Newt thinks Graves doesn't know it's him and uses this opportunity (because he has been harboring deep attraction to Graves for a long time). Graves, of course, is not an idiot and knows exactly whom he is fucking.
Double bonus points if Graves calls Newt out later ("How did you know?" "Well, for once, that giant hickey on the back of your neck is a dead giveaway - female or not, I remember where i marked you" ), and shows him that gender is not that important.
