Prompt (from LJ): Sam, Dean, gen, set any season, around April Fool's Day. Sam is fed up with all the pranks Dean is pulling on him, so he plans a prank of his own, something that causes Dean to maybe fall or jump into some body of water - it's up to you. But Sam doesn't know that he's already coming down with a cold, and he gets even sicker, and then he needs attention (and maybe cuddling) from a guilty Sam to get him all warmed up and feeling better.
Sam watches Dean get dressed. Undershirt, T-shirt. Flannel. Dean sneezes into his wet towel and drops it in the sink. Hoodie.
Hoodie.
"Are you still cold?" Sam runs a hand down his own bare arm and glances out at the garden centre across the road. There are tulips.
"It's cold id here." Dean's breath catches. He pushes out a breath and rubs his nose.
Sam raises his eyebrows. "Huh. You don't sound so good."
"Shut up."
"Yeah. Like you're stuck inside a phone booth. With a bassoon."
Dean cups his sweatshirted hands, double-gasps, and barks a sneeze into the long sleeves. He snuffles, then straightens carefully.
"You've got a cold."
"You're a geedius." Dean sags onto his bed and melds with the pillow.
"I didn't think... you never... a lake?"
"A lake. Id this weather? 'Course, a lake."
A man walks past the window in shorts.
"My bad, man."
"Takigg advadtage of by sedse of chivalry," Dean mumbles into off-white cotton. "Uhgr... ih-hhuh... HRRtzpfkggK-HOO!"
"Ouch."
Dean gropes the bedside table, knocking down a notepad and an alarm clock.
"Wait. Wait." Sam brings him a roll of toilet paper. The hands that take it are chilly. "Here. God. I'm sorry."
"You should be." Dean honks into the tissue and launches it at his head.
"Hey." Sam tosses his own comforter over Dean. "Be nice. I'll get you hot chocolate."
Dean's teeth audibly chatter.
Sam winces. "Damn it. You're really sick. Hold still." He dips in and rubs Dean's back through the blanket, fast and hard, back and forth, for friction.
Dean coughs, but doesn't move. "What is this, a peddigg zoo?"
When Sam gets back with the drink, Dean's sprawled in toasty sleep.
