When Blaine had invited Kurt over, he hadn't expected everything to turn out like this.
What he had expected was for Kurt to greet Cooper, shake hands with him and talk for a minute or so, then for Blaine and Kurt to disappear into Blaine's room to have 'treasured alone time'.
So what he hadn't expected was for Kurt and Cooper to sit laughing together on one sofa, and he himself sitting on the other, pouting.
"Oh, and did he tell you about his blanket?" Cooper snickered, shovelling abnormal amounts of M&Ms into his mouth. "He used to take it everywhere!" he grinned and offered some sweets to Kurt, who declined, laughing. "It was his best friend and—"
"Coop, didn't you say something about work? Places to go, people to see, that kind of thing?" Blaine was glaring at his brother, signalling heavily towards the door with his eyes. Cooper shrugged.
"No, actually. Anyway Kurt, I totally forgot, I promised to show you the pictures!" He grabbed a leather bound album from the shelf and sat down again. "Let's see..."
"No — you don't — don't you dare—" Blaine spluttered, making a mental note to steal Cooper's large supply of playboys from under his bed later, burn them, then scrub his eyes out with soap.
Kurt was cooing over the photo album, which was lying open on his lap.
"And that's the famous one of Blaine on the lambskin rug," Cooper was saying, pointing to the picture with a flourish and ignoring Blaine's whispered death threats and the fact that Blaine was rapidly turning an unattractive shade of red. Cooper looked at the photo thoughtfully. "I remember Mom taking that– then Blaine ruined the designer carpet because he had forgotten to put on his napp—"
"Shut up, shut up, shut it now!" Blaine had reached the tomato soup stage. Kurt smiled at him fondly, holding back giggles.
Cooper opened his mouth and stuck his crunched-up M&M-covered tongue out at Blaine, who was grinding his teeth. Cooper immediately - deliberately! - turned another page of the album. "God, I had forgotten he had had that teddy! He used to put bowties on it and wear a matching one, and run round the house wearing it without any other clothes on." Blaine groaned, pointedly looked at his brother and drew a finger across his throat, then very obviously looked at the knives lying on the counter.
Cooper wasn't phased. Quite the opposite. He smiled wickedly.
"So, you two done it yet? You must know, Kurt, Blaine here has a very strong phobia of—"
"Shut up, I am warning you-"
"Blaine frequently wet the bed."
"I will kill you in your slee—"
"And I haven't even started to tell you about the restaurant incident!"
"I will tell Mom about your magazines, Cooper Anderson!"
Cooper stopped mid-flow. Kurt was grinning, and Blaine looked very pleased with himself. Cooper was resembling a puffer fish.
"You wouldn't, Blaine."
"I would."
"You — you little—"
"I'll tell her what you really get up to at Uni—"
"No you won't, you idiot—"
"And I'll tell her about the time you were supposed to be on that camping trip, but really you were in Vegas!" Blaine finished triumphantly.
Cooper opened his mouth and shut it again. He blinked, defeated.
Blaine jumped up from the small couch and bounded over to Kurt. He took his hand.
"Come on, babe, we're going up to my room."
And they weren't interrupted.
