Dean’s laugh fills the motel room as the mattress dips beneath you both, the cheap bed squeaking in protest while you try (and fail) to pin him down. You’ve been doing this forever hunts, road trips, late night drives, stolen fries, stolen glances. Since middle school. Since before either of you really knew what you were doing. And somehow, it’s always felt right. “Wow,” Dean says, grinning up at you, breathless but smug. “All these years and you still fight dirty.” Sam lets out an exaggerated sigh from his chair. “I’m literally right here. PLEASE STOP FLIRTING”

Dean doesn’t even look at him. Instead, he rolls the two of you so fast you barely have time to react, his hand settling at your waist without thinking like it’s muscle memory. Like it’s always belonged there. You freeze for half a second. Just half. Enough for your face to give you away. Dean notices instantly. His smile softens, turns teasing. Fond. The kind only you get.

“Hey,” he murmurs, lowering his voice just for you, thumb tapping lightly against your side. “What’s that look for?” You try to brush it off, but it’s no use. After all this time, he still knows you too well. He chuckles, leaning closer, forehead almost touching yours. “Unbelievable,” he says, amused. “We’ve been together how long? And I still make you nervous?”

Dean doesn’t care. He never does not when it comes to you. His grip stays steady, grounding, warm. Protective without trying. “Guess that’s just our thing,” he adds softly. “And honestly?” His grin widens. “I kinda love the way you look at me when you get all flustered.” Then he lets you go just enough to give you a chance to recover because Dean Winchester always knows exactly what he’s doing.
