1. In which all angels are naturally cold
As it turns out Lucifer isn't the only angel who burns cold. They all do, and why not they're made from left over particles of stars, and space is a very cold place.
Only Sam doesn't know that, not at first.
He's always wondered why Castiel dresses in so many layers, why he refuses to take off his trench coat. He just figured that angels were simply unaffected by weather conditions. It isn't until much later that he figures out why Castiel never seems to break a sweat when he's covered head to toe in the middle of summer.
Not until they fall into bed with one another, eager mouths moving against one another the unsaid 'why didn't we do this sooner' hanging in the air as Sam settles between the angel's thighs.
The angel isn't cold then; flesh hot as Sam kisses his way across the pale expanse, his own hair falling forward slick with sweat as he rocks his hips into Castiel. The angel moans, a low guttural sound at the back of his throat as his fingers dig into Sam's arms hard enough to ensure there'll be bruises in the morning. Sam's close, it's been a while for him and Castiel is just so tight and perfect around him, a litany of breathy gasps and moans pouring from the angel's mouth is almost enough to do him in.
The final straw is the way the angel's mouth latches on to his neck, messy wet kisses being given as he gasps out "Sam", impossibly blue eyes blown wide as he cums against Sam's stomach. Sam follows after, head buried in the crook of Cas' neck as he lazily rocks through his orgasm.
No, Castiel is definitely warm then, it isn't until later when they're lying face to face, legs tangled together that Sam actually finds out just why the angel is constantly covered.
Sam is a human space heater he's always warm, the same cannot be said for Castiel. Shifting closer to Sam the angel's feet brush against Sam's calf, sending an ice cold shiver up the younger hunter's spine, and now he gets it.
Angels are naturally cold, and now without the cover of Jimmy's wardrobe, Castiel is downright freezing, so he wraps his arms a little tighter around the angel tugging him close, hands rubbing along his back in an attempt to warm the angel. Castiel hums softly nuzzling against Sam's chest and Sam smiles a little knowing he's the one to warm Castiel.
