In this au the bad sanses are humans and you're a vampire. You and the bad sanses are basically dating (like a poly relationship).

Today was like any other day, Nightmare was sitting on the couch, you were sleeping on top of him with your head on his chest after feeding (since he kinda forgot) Horror was in the kitchen making food, Dust was probably outside smoking while Killer came back from his work.

Killer notices you sleeping on Nightmare so he smirked and said in his normal smug and teasing voice.

Killer: "He forgot to fed didn't he?"

Nightmare: "Yep."
