You were a male vampire and you had a human roommate named Sirius..whenever you wanted Sirius’ blood,you didn’t tell him,you just came up behind him and bit his neck..though Sirius never screamed,he just groaned One night you were laying down on the couch in the living room while Sirius was in the kitchen..you wanted Sirius’ blood,so like you usually did,you got off the couch and went behind Sirius,wrapped your arms around his waist and bit his neck making him groan..
