I don't own Glee, I don't even own Klaine, but I do enjoy shipping them.
Season 5, Episode 16: "Tested."
Closing in, breaking out…
After Blaine moved into the loft, he just wanted to be close to Kurt. Long distance was hard. He felt like he needed to make up for lost time, unfortunately Kurt was starting to feel smothered. When he was talking with Eliot, he was wondering what to do. He believed they were end-game, but at this rate he would start resenting Blaine if they didn't manage to work something out.
Kurt had his band, his friends, whereas Blaine hasn't had time to work things out for himself. He knew what everyone would say, they moved too fast and now they can't crack it in the big city. But, he had to speak up.
He dreaded this; he loves Blaine and doesn't want to hurt him. When Blaine got home, he took a deep breath and started.
"Blaine, I feel like we need some space. We never talked about what we would do when you moved here. I think with us going to school together and spending all this time together, it's too much."
"I'll move in with Sam." Blaine said. "I understand."
"It's not like we're breaking up or anything." Kurt said anxiously.
Blaine pulled him in and started kissing his neck making Kurt let out a sharp gasp.
"While this isn't technically a fight, I don't see why we can't go into the other room and have spectacular make-up sex, anyway." Kurt responded, letting himself be dragged into the bedroom by Blaine.
Kurt had grown into himself a lot during the time they had gotten together. He undid his fiancés shirt, stripping him down slowly, kissing the exposed flesh and nipping gently at him, making Blaine gasp in response. Then he pushed him down on the bed.
He then undressed himself, giving Blaine the sexiest gaze ever, before moving to divest the other man of his jeans. He peppered kisses on the inside of Blaine's thighs, seeing Blaine's boxers stretch against his aching length. Blaine let out a sigh as Kurt removed his boxers, making his hard-on spring free. Kurt bent down and took his cock into his mouth. This took Blaine by surprise. His lover didn't often give him head, but when he did, Blaine loved it.
Seeing Kurt's blond hair and those soul-piercing eyes almost made him come undone before they even started.
"Babe, wait." He gasped, before he climaxed too soon. It had been a while, so he didn't want it to be over so quickly. He flipped his fiancé over onto his back, spreading his legs and preparing him with their ironic pink lube in kept in the drawer, Kurt bit into the pillow as to not moan too loudly.
They had some loft rules that got made because of Rachel and Browdy (who sounded like animals in the bedroom).
When Blaine entered Kurt, they both moaned, it was a feeling of being again united as one, something Blaine had never felt before.
That was how he knew, the first time he took the other man's hand into his, as they ran down the hallway of Dalton Academy; this was his soul mate. He knew he wanted to be with this man forever and he would do anything to make their relationship last, even if it meant letting go and seeing if Kurt came back to him.
In that moment, nothing mattered but their love.
