Heat
With the sun blazing down and the heat not seeming to be letting up, it's going to be a long summer. Although he'd never usually admit it, Blaine loves it. Even though he's sun burnt on the back of his neck and he's sweating enough to drown it's worth it just to see Kurt.
In summer Kurt has no choice but to take off some layers, he sits in the garden with Blaine in just a vest and his hair sticking up all over his head. It's too hot to be comfortable but he can take it to get to watch Kurt's muscles flexing while he tries to put on sun lotion, eventually calling Blaine over to rub it into his back, to which he happily complies. Sometimes they'll just stay in the house with the windows open, feeding each other ice cream and sucking ice cubes into one another's mouths when they kiss. Kurt likes to pour cold water onto Blaine's chest and lick it from him, Blaine thinks he just like to watch him shiver.
But most of all he loves the nights. Kurt gets restless and can't sleep in the heat most nights, so they sleep naked and Blaine kisses him and sucks wet kisses onto his collar bone, running along his jaw tasting sweat and making Kurt gasp in the empty house. He likes it best when Kurt gets so hot it makes him woozy and too tired to fuck, so Blaine can ride him. They fuck slow and deep, Blaine riding Kurt into the mattress and watching him sweat and moan beneath him. When the heat gets too much they can take a shower and let cold water run down their backs, Blaine likes to stand and watch Kurt's face when the cold hits him and then squeal when Kurt flicks some at him before he's got in, resulting in a lot of kissing and unfinished showers.
Blaine just really loves summer with Kurt.
I Will Form
Blaine finds that living with Kurt might be one of the best decisions of his life.
At first it's just the joy, the rush of being able to say home and mean it. Actually mean somewhere that they both live and sleep and be together. It means a future, and it means a definition of I want to be with you, and more than just a long time. After a week or so Blaine finds there are some little things about it that outweigh the rest.
He loves to wake up next to Kurt, getting to see his face so serene and still from sleep, lips just a little pursed and begging to be kissed. Blaine will sometimes just sit and watch him for a while, staring at his eyelashes fluttering every once in a while and running his fingers just barely over the bumps of Kurt's spine until he awoke.
He loves to get out of the shower and drag himself down the stairs, to find Kurt making pancakes wearing just one of Blaine's old super hero shirts. His bare feet padding on the kitchen floor and the curve of his ass through the thin material. Blaine loves that he can walk up behind him with his towel loosely around his waist, wrapping his arms around Kurt's and kissing him with the lazy haze of the morning between them.
He loves to be able to make love to him wherever, and whenever he wants. Them being able to fuck as loud and recklessly as they feel like because it's their home and they have time and sometimes they just can't resist being louder than usual. Blaine loves to pull moans and high pitched cries from Kurt just because he can, he knows Kurt loves it just the same.
