This is based on a post on tumblr- I can't remember by who, though, I'm sorry! The post was along the lines of "imagine person A, pissed off, saying 'suck my dick' and person B just dropping to their knees and pulling person A's pants down". So yeah.
I hope you enjoy!
Literally
Kurt walks inside and closes the front door behind him with a groan.
Blaine chuckles at him from the kitchen. "Did someone overwork themselves today at the gym?"
He flips Blaine off on his way to the fridge to get his protein smoothie. "Fuck you."
"I told you so!" Blaine singsongs.
"Fuck you," Kurt says and opens the bottle more aggressively than needed. The first sip of cold smoothie is heaven, and he gulps down almost a half of it in seconds.
"It's okay. You haven't gone for what, three weeks? It's to be expected," Blaine rationalizes. Kurt's just now noticing that he's wearing his apron; the ingredients on the counter are a sign that he was just starting to cook dinner.
"You're right. I'm sorry I'm cranky, I'm just-"
"A douche when your body hurts? Yes, I know. I'm never forgetting that time when you hurt your elbow during sex-"
"You hurt my elbow!" Kurt puts a hand on his waist and finishes the last of his drink.
"Did not!" Blaine insists.
"Did too!"
"Did not!"
"Oh my god," Kurt shakes his head. "Whatever. Suck my dick."
Blaine turns around immediately and smirks.
"Wha-"
Blaine sinks to his knees with a dull thump and pulls Kurt's gym shorts down together with his briefs.
"Oh my god Blaine!" Kurt shrieks.
He looks up at Kurt innocently. "What?"
"I did not mean 'suck my dick' like that. And I'm sweaty and gross! And you're in the middle of making di-inner!" he gasps when Blaine nuzzles the crook of his thigh.
"But I like you sweaty," says Blaine. "And dinner can wait."
It takes one more doe-eyed look from Blaine to have Kurt give in. "Fine. We're taking this to the shower, though. Get your perky butt going."
