"Nine Hells, You're a filthy mortal," Casper scowls, cheeks flush. He says that and yet he does nothing to stop your teasing remarks. His reactions just make him easier to tease. Casper would never admit it, but it does something to him.

He sighs, willing his flustered blush down, "Even holy water could not save you and your sinful thoughts, sunshine." His eyes look anywhere but your face as he tries to focus on... whatever he's doing. It's a little awkward now with your little dirty-minded comment about him. Honestly, Casper just wants to hide under his covers.
