A Ducifer headcanon dump because I’m drowning in the feels T^T
Lucifer developing a fascination with Dean’s freckles and tracing over them when their lying together, while he’s sated after sex, or when Dean’s asleep, so he can slowly and methodically count them. Dean doesn’t understand and he tries to question Lucifer about it, but Lucifer just shushes him and continues to trace his skin, until Dean let’s the gentle pattern of Lucifer’s fingers on him skin lull him to sleep. Since Lucifer is an archangel, he has infinite patience and doesn’t get tired. So far he’s in the low 1000’s.
Lucifer also developing a fascination with Dean’s hands, at all the scars and callouses on his hands, but also at the way they’re so firm and graceful and steady in everything he does, whether it’s to stitch his brother up after a really bad hunt, or if it’s cleaning his weapons. His favourite thing to is to watch Dean hands methodically unassemble and assemble his gun so that he can clean it.
Lucifer takes some kind of weird pleasure in watching Dean as he works in the kitchen. Dean actually doesn’t mind but sometimes he finds it creepy when he continues to watch him with that quiet intensity of his for long periods of time. When he finally snaps and asks him about it, Lucifer just shrugs. “I like watching you” Dean says nothing and goes back to work and Lucifer pretends that he doesn’t see the way the tips of Dean’s ears have gone red.
Lucifer being extremely protective of Dean to the point where it annoys him. As a hunter, Dean is used to taking risks…it’s what he’s done his whole life. Lucifer HATES this. If it were up to him, he’d have tied the hunter down and kept him by his side forever (and has even on occasion tried to sneakily put a binding spell on him, but that had led to no sex for a week when Dean find out, so he didn’t try that again). Dean’s too smart. If Lucifer had it his way, Dean would probably find himself locked away bound and naked in Lucifer’s bed in some faraway hidden place, for his eyes only. (And no, the idea doesn’t send a secret thrill down Dean’s spine at all). But Lucifer now knows that nothing can control this beautiful strong hunter and his strong sense of justice, so he has no option but to let him go. But he’ll never stop trying ways to make Dean stay.
When they’re lying together, Dean notices that Luifer’s hands like to wonder a lot. Particularly over his stomach and his chest, where his fingers trace warm patterns into his skin over and over again. At first Dean thinks it’s just random, but then he realises that he’s tracing patterns, his fingers running the same route over and over again. And at first Dean can’t figure it out but then later he realises that he’s tracing enochian protective sigils into his skin. Lucifer knows that he can’t protect Dean by keeping him with them so instead he marks the symbols into his human’s skin, so that everyone will know who the hunter belongs to. To Lucifer Morningstar. And if anyone tries to get in the way or harm his human, they know what they’re getting into.
Dean not understanding why Lucifer would ever be in love with him and Lucifer holds him down and gently tells him all the ways in why he’s so special and the reason he fell for him. Presses fierce kisses all over his body and he whispers into his skin all the reasons why he loves him. How Lucifer is in awe with how beautiful and brave and oh-so selfless Dean is. How he always puts everyone else before him. How beautiful and bright and pure his soul is.
Dean being really embarrassed and trying to hide his body from Lucifer, or covering his face with his hands, but Lucifer pulling them away and reverently worshipping and exploring every inch of his body
Dean crying when Lucifer says so because it’s the first time that he’s ever had someone focus that much attention on him and love him so completely despite all his flawss
