Black Butler boyfriend/girlfriend scenarios

How you two sleep

I don think demons sleep, but for the sake of the story, they will.

Sebastian- You and Sebastian sleep with your back turned to him and his face in your hair. You two also hold hands while you sleep.

Ciel-  You and Ciel sleep on your sides facing each other.

Alois- How you and Alois sleep is completely up to Alois' mood. If he's happy he will sleep with his arm tightly wrapped around you. If he's sad or upset, you hold him and his head will be laying against your chest, he likes the sound of your heart beat, it calms him. If he's in another mood he will lay on top of you, while you are holding him.

Grell-  You and Grell sleep taking turns each night on who holds who. One night Grell will hold you close, and the next you would be holding her close to you.

Undertaker- Undertaker lays on his back, with your head laying on his chest and his arms wrapped around you.
