Tap
"Blaaaaine," says Kurt slowly, like his tongue is too big to fit in his mouth. They've been out with their friends, and while Blaine has been the designated driver, Kurt hasn't held back on the tequila shots.
"Yes, darling?" says Blaine, smiling at his drunk husband as he slides off his button-up and puts on a clean t-shirt.
"Why do people…" Kurt drifts off for a moment before focusing again. "Why do people say… Why do people say 'tap your ass'?" he buries his face in the pillow.
Blaine chuckles. "I don't know, darling." He finishes dressing and crawls on the bed, lying parallel to Kurt and smiling at him.
"I mean, it doesn't… doesn't make sense," he hiccups. "You don't just go-" he reaches out and taps Blaine's butt with a finger a few times. By the time he's finished demonstrating, Blaine is shaking with laughter, pressing his lips together and tearing up.
"See? That's… not very… arous- arousi- hot."
Blaine wipes away his tears and kisses Kurt for a moment, his lips warm and open. "You're adorable, you know that?"
Kurt smiles and pats Blaine's butt, then leaves his hand there as he snuggles closer. "Thank you," he barely manages to get out before yawning a gigantic yawn.
"Go to sleep, darling. You can tap my ass all you want tomorrow, alright?" he says with another giggle, and then realizes that Kurt is already snoring; he kisses his forehead lightly. "Love you, K."
