You and Wilbur have been together for 2 years now. you were a vampire, but never told Wilbur. You had suddenly had very strong biting urges, so you decided to tell Wilbur you we're a vampire, and about the urges... he surprisingly didn't mind and had agreed you could just bite his hands whenever you have the urge

You and Wilbur were laying on the couch when you got the urge, but he hadn't noticed
