This is an extremely late birthday present for colfhummel. Yes, I am ashamed. BP!Kurt and Sebastian in an established relationship. Sex. Nothing out of the ordinary. 4,2k. For full list of kinks and such, refer to ao3.
“So, your birthday is coming up,” Kurt says when they’re settled on the subway. They’re on their way to Sebastian’s friends Halloween party, dressed in semi-matching costumes and working hard on keeping their hands off of each other.
“Mhm. So?” Sebastian says, pressing his thigh closer against Kurt’s.
“So,” Kurt says, squeezing Sebastian’s hand. “What do you want? Do you want to do anything special, do you want a gift?”
Sebastian snorts and rearranges himself, slips his hand out of Kurt’s and slides his arm around Kurt’s waist instead. “No, I don’t want a gift. I don’t want to do anything.”
“Yes, really. It’s no big deal.”
Kurt tries hard to keep his face in check and not let his surprise and shock show, but judging by Sebastian’s entertained expression, he’s failing.
“But…It’s your birthday,” Kurt tries to argue. He doesn’t have a better argument than that, though, and he hears how weak it sounds.
“Yeah. But I’m only turning twenty-two. It’s just another day.”
“But there’s gotta be something?” Kurt tries.
Sebastian leans in, puts his mouth so close to Kurt’s ear that his breath makes Kurt shiver. “Well, if you really want to give me something, you can let me fuck you.”
