Domestic!Destiel with canon bunker setting based on this tweet:
Dean takes his time in the shower. It’s the one thing he’s extremely grateful for in the bunker. The water pressure is just perfect, beating down on his back and shoulders. There’s a rhythm in his head that’s been in his head the entire day and he begins to sing. Rubbing his hands over his face and ducking his head under the water he doesn’t hear anyone open the door. Hell, he didn’t even realise he forgot to lock it - years of living in motels with just his brother meant he hadn’t really needed to.
He’s just grumbling the chorus when he hears the shower curtain sliding open and whips round with a yelp.
When he blinks water from his eyes and covers himself as best he can with the small face cloth he find Cas staring at him with a bag of crisps in his hands.
“Cas!” He yells. Cas isn’t moving though and hold the crisps out in front of him.
“CAS!” Dean yelps again.
“Are we - Dean, stop screaming, it’s just me… are we out of cheetos?” His eyes are wide and look impossibly blue in the bright bathroom. For a moment he forgets that he’s only got a face cloth covering himself.
“What? Cas, you’re holding the empty bag, of course we’re out of cheetos.” Cas’ eyes grow wider. Dean sighs. “I’ll make a run… just… just leave me for a moment to finish.”
“Thank you, Dean.” Cas grins. Dean’s pretty sure he is on the verge of melting at that look and smiles back. Cas has gone through eight packs of cheetos in the last week and he’s sure that it’s unhealthy, but buying more of them will make him happy and a happy Cas is a happy Dean. Plus, when they’re pressed against each other watching TV, Dean can’t help but dip into them.
