I was messaging with trufflemores and spawned a headcanon which spawned this drabble. I'm sorry for your dentist bills.
Kurt was exhausted.
It was midway through finals week at NYADA, and he had thankfully gotten through his "Comedic Acting" monologue okay, but he had Cassie's "Intensive Jazz for Dummies" routine tomorrow, and she had already informed them that one mistake got you an automatic C, and two got you a failing grade. He'd been practicing ever since he got home that day, and now his legs were almost audibly protesting having to ever move again.
"Kurt? Baby, it's been five hours," called Blaine from his spot on the couch. He only had one final left, and it wasn't until Friday, so he was rewarding himself by marathoning Toddlers and Tiaras. Kurt was incredibly jealous. "If you don't stop, you literally won't be able to move tomorrow. Come snuggle with me!"
"You're so needy," Kurt teased as he slowly ambled his way out of their bedroom and into the living room, flopping down on top of Blaine, who let out a quiet "oof" as Kurt's weight landed on him.
"No, I'm concerned and also a little cold, and you make a wonderful blanket," said Blaine with a grin, prompting a faux scowl from Kurt, who had pillowed his head on Blaine's chest.
"So you're just using me for my body heat. I see how it is!" Kurt said with a pout. "I'll kick you out in the snow, Blaine Anderson, see if I don't."
"Rachel would never let you kick me out, I help her run duets all the time," responded Blaine, running a hand down Kurt's spine comfortingly. "She might like me more than you at this point." Blaine punctuated that sentence with a wink.
"I should be madder about that, but I'm too sleepy to argue anymore," Kurt said, yawning partway through his statement. "Keep rubbing my back and I could be persuaded to forgive you, though." Kurt started to curl up against Blaine's chest, eyes closing in contentment.
"And you said I was a cuddle monster," Blaine said fondly, hearteyes in full swing and TV marathon completely forgotten.
"Because you are," huffed out Kurt, almost asleep. "You almost didn't let me out of the bed this morning."
"Details, details. Shhhhh, baby," Blaine said quietly, moving his hand that wasn't stroking Kurt's back up to tangle in his hair and scratch lightly at his scalp.
"Oh, now you're fighting dirty," Kurt slurred. A few seconds later, he was dead to the world.
Blaine smiled one last time at his worn out fiance before shifting to grip Kurt in his arms and carry him to bed.
Kurt woke up just slightly as he felt himself being lowered onto the mattress, long enough to hear Blaine whisper "I love you, baby," and kiss him gently on the forehead before dozing off again.
