Graves topping the fuck out of somebody, basically. Could be Omega credence, wide-eyed and broken, maybe never heard of werewolves and now he's being chased through the woods by this terrifying thing that has him pinned down and is clawing his clothes right off...could be Magizoologist Newt trying to help Graves control the change, all gentle and understanding, but he smells so damn good and Graves just wants to get up in his face and lick his freckles and knot him until he screams....hell, could be werewolf!Graves with Tina or Queenie or whoever. Just hot, dirty, dubcon/noncon werewolf sex.

Bonus points if Graves feels absolutely racked with guilt when he's human again
