Calum:
With cold breezes running over the skin of his arms, the only body parts sticking out of his sheets besides his head he knew something was up. He wasn't the person to wake up in the middle of the night for nothing but the second you're not embraced in his warm arms he can't sleep. Squeezing one eye open after not getting a touch from you while sticking his arm out his curls are stuck to his forehead with a tired smile on his face. You're far away, not aware of your distance and he allows himself to rest his cheek on your chest, the heavy breaths from you lullabying him back to sleep by the single touch of you.
Michael:
It was barely a second you got the chance to turn around to rest on your side, pain in the back forcing you to change your position. And even if Michael's snores were loud in the bedroom it all stopped the second you weren't touching any longer. Mumbles and groans escaped his lips tiredly but it all stopped the second he wrapped his arm around you lazily and pulled you into his chest. He never knew how addicted he had become of you before he went on tour. And it meant the second you were the slightest gone his body would register it. He needed his cuddles and it always had to be from you. Always.
