During the actual meal, Blaine excuses himself to get something out of the kitchen. Later, he can't even remember what it was or if he actually brought it to the table, because as soon as he steps back into the dining room, his brain freezes.
Kurt is just sitting in his chair, humming along with the music as he takes the tiniest sip of wine. When he spots Blaine, this grin spreads across his face, soft but brilliant and Kurt wiggles his fingers to wave. And Blaine wants to kiss him so badly that it aches and that's when his brain turns on to remind him you can totally be kissing him right now.
So, he forgets what he was doing in order to cross the room as quickly as possible and pull Kurt out of his seat. A little bit of wine sloshes onto Blaine's shirt, but he doesn't really care, because he can feel Kurt smile briefly against his mouth before he swipes his tongue against Blaine's lips.
They keep it light for a little while, kissing and running hands gently through hair and over the curves of one another's faces, when suddenly everything shifts just right. Blaine's left hand manages to undo the buttons of Kurt's summer cardigan as the right, seemingly dazed, rests on the curve Kurt's neck. He's warm and rosy pink and looks so innocent with his big blue eyes half-shut that Blaine is taken completely by surprise when Kurt presses his hips into Blaine's suddenly.
"Hey! You okay?" Blaine asks, pulling away suddenly. His voice has dropped to something husky but giggly, making Kurt smile.
"I'd be better if we were on the couch," Kurt replies; a little surprised to find that his voice dropped even farther, no where close to a countertenor now.
"The couch? Oh dear, do you need to rest after my wonderful cooking?"
He's teasing Kurt, his mouth swollen but set into a serious line. Blaine's eyes ruin it, though, shining a brilliant gold with his eyebrows nearly touching his hairline. Kurt presses their hips together again, a wicked grin to match Blaine's forced seriousness. It has the desired effect of: A) convincing his boyfriend that 'rest' is the last thing on his mind and B) getting said boyfriend to scoop him up so they're chest to chest and lead him to the couch while kissing Kurt hard.
In the background, there's a pause in the music as the song slips. The next one is a bit too fast compared to the rest of the mix and it sticks out like a sore thumb. Neither Kurt nor Blaine notices, too wrapped around and in each other to care about it right now. This is something they've been wanting all summer but never got between Kurt's summer job at the shop and Blaine going to as many auditions as possible and both of their families.
None of those things matter now, because they're together and alone in Blaine's house. Kurt is spending the night and staying until his shift starts at three tomorrow. The next day, he plans to surprise Blaine by picking him up for dinner and a movie. Right now, he kisses Blaine's neck, trying to keep himself from leaving a hickey. Blaine, meanwhile, begins to undo his belt and Kurt thinks good thing these are only plain skinny jeans and then Blaine's hand is my pants and then all his thoughts go hazy.
It's okay. They've got time for thinking later.
