HOW YOU SLEEP-
Ashton:
Spooning. He'll never let go of you when your both sleeping. He'll have his arms around your waist, pulling you as close as he can, nuzzling his head in you neck.
Michael:
He might not seem like it, but he likes it when you sleep with your head on his chest, so he can feel your heart beat with his. He'll rest his hand in your lower back, slowing drawing circles with his fingers.
Calum:
He loves it when you face each other when sleeping. Noses almost touching legs intwined, his arms wrapped around the curve of you waist. Both of you mirroring each other. Then in the morning, he loves it when he opens his eyes to his true love before him. ( also he is a naked sleeper ;D )
Luke:
Luke loves it when you sleeping topless. Not naked, just topless, both of you. He'll sleep on your chest, and you'll wrap your SMS around him. You heart beat soothes him to sleep. He loves feeling your smooth skin on his face in the mornings.
