Sup, so Dean and Cas are going out. If you want, this can be in the series. I just imagined this as them being a bit younger.
Castiel was sick. Dean had woken up to his boyfriend groaning and holding his head beside him.
Dean had instantly broken out the chicken soup and blankets.
For the whole day, Cas had been given blankets every ten minutes and an unlimited supply off chicken soup.
"Dean..." Muttered Cas, a hand snaking out from under the avalanche on blankets piled on him.
"Dean, come to bed." His voice was even more gravely than normal, deep and rough.
"Its half three in the afternoon."
"I'm cold?"
"You have over fifty blankets, Cas and the heat is on full blast. You're paying that bill."
A sleepy, blue eye cracked open and squinted up at Dean.
"I need you, Dean."
Dean rolled his eyes and sighed. He crawled into bed next to Cas and rearranges the blankets so he was covered a bit.
Cas snuggled up beside him, sighing happily, his head tucked under Dean's stubbly chin. Dean clutched onto Cas' pyjama-clad shoulders.
The second Cas started snoring, Dean dropped the scowl and nuzzled down into Cas' sweet-smelling hair.
He gently swept his sweaty locks away from his forehead and kissed his forehead.
"I love you." He whispered.
Cas shifted closer to him, trying to keep warm.
"I love you too," came his half-asleep reply, muffled from Dean's chest and three hundred blankets.
