i love samdean kisses that feel less like romance and more like finally snapping after holding themselves back for way too long. all that restraint just gone in seconds.
like dean going into it thinking he’s gonna be gentle because it’s sam, because it’s sam, because he’s spent his entire life trying to protect him from everything including himself. and then sam kisses him back too hard, too eager, grabs dean by the shirt with both hands like he’s scared dean might disappear if he lets go for even a second, and suddenly dean’s slamming him into the nearest wall with this awful desperate noise caught in his throat.
and the thing about them is they know each other too well. they know exactly what gets a reaction. dean knows sam gets shaky when somebody holds the back of his neck. sam knows dean loses his mind when somebody touches his waist, gentle and grounding, like he deserves tenderness.
their kisses are never neat. they’re messy and breathless and a little painful sometimes. mouths bumping together wrong because they can’t slow down long enough to care. dean accidentally catching sam’s lip with his teeth and immediately trying to apologize only for sam to kiss him harder for it.
and god, the grabbing! sam clutching dean so tightly it almost hurts, fingers twisted in flannel and leather like he’s trying to anchor himself. dean with both hands on sam’s face one second and gripping his hips hard enough to bruise the next because he genuinely doesn’t know what to do with the sheer intensity of wanting him.
i think they’d both get overwhelmed by it really easily too. all heavy breathing and foreheads pressed together afterward because they kissed so hard they actually got dizzy. dean laughing a little under his breath, stunned by it, while sam just looks wrecked in that big-eyed silent way he gets when he feels too much at once.
