I bet there're a bunch of people who have done this already, but I just wanted to do my own because really, who can get enough of Klaine?

(p.s. I can't remember much of the dialogue, apologies if I got anything wrong!)

Disclaimer: I do not own Glee or Baby, It's Cold Outside.

"Blaine? Please, I'm studying-" Kurt started, only to be cut short by the older boy's finger on his lips.

"Shh. I'm not Blaine. I'm Marley's ghost, and I'm here to tell you that you need to stop working so hard. It's Christmas." Blaine grinned, placing the portable radio he had brought in with him on a table. "C'mon, Kurt. Loosen up a bit. I need you to help me with a song that I'll be singing at King's Island." Kurt raised his eyebrows at this and closed his book after leaving a bookmark in it.

"Which song?" Kurt asked, standing up.

"'Baby, It's Cold Outside'," Blaine answered hastily. He pressed the 'play' button and Kurt smiled, singing the notes perfectly.

I really can't stay.

Blaine stepped forward, singing his part before Kurt finished his.

But baby, it's cold outside.

I've got to go away.

But baby, it's cold outside.

This evening has been...

Been hoping that you'd drop in.

...so very nice.

I'll hold your hands, they're just like ice.

My mother will start to worry.

Beautiful, what's your hurry?

They scurried around the room, playing pretend that they were chasing each other around the room.

My father will be pacing the floor.

Listen to the fireplace roar.

So really, I'd better scurry.

Beautiful, please don't hurry.

But maybe just a half a drink more.

Put some records on while I pour.

The neighbors might think.

Baby, it's bad out there.

Say, what's in this drink?

No cabs to be had out there.

I wish I knew how...

Your eyes are like starlight now.

..to break the spell.

I'll take your hat; your hair looks well.

I ought to say no, no, no, Sir.

Mind if I move in closer?

At least I'm gonna say that I tried.

What's the sense in hurting my pride?

I really can't stay.

Baby, don't hold out.

Ah/Oh, but/Baby it's cold outside.

They sang the line together, smiling widely at each other before continuing the next verse.

I simply must go

But, baby, it's cold outside

The answer is no

But, baby, it's cold outside

This welcome has been...

How lucky that you'd drop in

...so nice and warm.

Look out the window at that storm.

My sister will be suspicious

Kurt definitely knew what the next part was, but he hadn't expected what happened after.

"Gosh, your lips look delicious," Blaine murmured, leaning towards Kurt. He placed a hand under Kurt's chin, tilting his head just slightly so that their lips would touch each other. Blaine captured Kurt's lips in his and Kurt jumped a little in shock, but otherwise remained momentarily stunned by the split-second moment. Blaine let his hand drop as he moved out of the kiss, smiling softly. Suddenly, as if he was broken out of a trance, Blaine took a step back and covered his mouth with his hand.

"O-Oh my god, Kurt. I'm so sorry. I just- I- I'm so sorry, I don't want to seem like another Karofsky- I just- I- I-" he stuttered, sighing as he looked at his best friend who was biting his lower lip. "I-I'm just- I'm sorry." he mumbled, running a hand through his hair in frustration.

Kurt took a step forward, eyes soft. "How can you be another Karofsky when I love you?" he whispered, placing a chaste kiss on Blaine's lips.

"I've been looking for you forever."

I am going ecstatic with joy as I'm listening to 'Baby, It's Cold Outside' on a continuous loop while writing this. I hope you liked this! Reviews are welcome! (:
