Dean started every morning the same; with him slamming his hand over the snooze button, grumbling obscenities until his body woke up, and being forced to untangle himself from the warm body next to him.
He always somehow managed to make it to the kitchen dressed and clean, and then proceed to glare at the clock - 5:36 it read this time - before he would think up some dumb joke about how he should not be up before the sun that Cas wouldn't be awake enough to hear.
Castiel would make coffee and the sweet aroma would open his eyes for a few minutes. Cas would place the coffee down in front of him before heading to the bedroom to change. Dean drank aimlessly until he heard the foot steps behind him and the hand reaching forward to snatch his coffee. Some mornings he would make a fuss over this and claim his mug back, knowing there was enough for the both of them in the coffee maker. But instead he just smiled, a small quirk of lip, and pulled Cas down.
The kiss tasted like coffee, tangy and sweet. When they pulled apart there was a smile on their faces, and they were both suddenly awake.
The rest would be a rush of movement as they both prepared for their day. While Cas fixed his tie Dean would steal the croissant he had in his mouth (as revenge for the whole coffee thing) and fix his tie for him. Cas would mutter that he could do it himself, but he would let Dean do it anyway because deep down he liked those moments where Dean would try to hide the smile on his face as he grumbled about how incompetent he was.
This time when Dean finished adjusting his tie he would glance up and lock eyes with Cas. And he would use the tie to pull Cas towards him and they would share another kiss. He would tangle his hand in Cas' hair - which he was sure Cas was going to complain about later while he was leaving - and wrap his arms around his waist. They would stay in that embrace for a few stolen moments, knowing they had places to go and things to do but also knowing it didn't matter because the sun was warm on their backs and Dean's fingers were pulling him even closer and the kiss tasted like cinnamon bread instead of coffee.
Then, like always, Cas' found rang and they had to split apart. Dean would sit back down and finish his breakfast, sneaking glances at Cas smoothening out his slightly creased suit. And again he would think about why in the world a big shot lawyer like Castiel would want to be with a greasy mechanic who dropped out of high school. But then he would shake those thoughts out, because it didn't matter how or why, it only matter that they were here having another perfect morning together and knowing they were many more mornings like it to come.
And while Cas was heading out he complained about his rumpled hair before closing the door behind him.
