how about wall slamming sex? like, cas and dean just got in a huge fight and they’re yelling at each other until dean slams cas up against the wall, and soon enough he’s fucking growling, kissing cas hotly and opened mouthed while cas just squeaks at the mere surprise of it
but then cas gets into it, and then their hips are rocking together and the two are moaning and cas just needs more as dean presses him harder into the wall, and then the two are fumbling with clothes, practically ripping them off of each other as they slowly become pools of fabric on the ground
and dean is desperately searching for lube before he finds it and he pins cas to the wall again, cas who wraps his legs around dean, and dean wastes no time shoving his fingers inside of cas until castiel is whimpering and panting
and dean is fucking breathless when cas slides down on his cock, and castiel just makes this little noise of bliss before they’re back to where they started and everything is rough as dean bites into cas’ skin, as he growls and cas just claws at him desperately, feeling every single punctuated thrust dean has to offer until he can’t take it anymore and he’s coming, and dean is doing the same, muffling loud groans into cas’ shoulder before they breath heavily, slowly sliding back down to the floor where the kiss each other languidly, offering begrudging apologies and shy smiles as they interlace their fingers.
