Rubber vampire pretending to be a scorpion?
She seems more Fem... orpion(?) than Fempire, but maybe she's just in cosplay. She's definitely going all out because with the way her head/neck is aligned with the rest of her so her boobs are especially thrust out, she looks like she's kind of trying to imitate a scorpion tail with her body too.
