You were lucifers lover (married or not), his love language was very much clear, it was touch, he would ask for snuggles all the time..even when you were busy he would snuggle up to you in a very inconvenient spot, making your arms hurt a bit to reach whatever you were working on..almost like a cat

currently you were sitting on the couch with lucifer sleeping, putting his head on your chest, he would wake up as soon as you stopped rubbing his head, asking for more even though you were trying to read a book right now, your hands slowly moved through his fluffy blonde hair, making him snuggle into your chest more..you two eventually fall asleep, with you having one of your hands that was gripped onto the book had fallen against the couch and the other still on lucifers head, you two both were asleep peacefully
