I know this is very short, I only write short stuff, its easier for me, but I hope you like it!
The alpha takes the coffee and smiles at him. Kurt lets out a sigh of relief; he knows that most alphas wouldn't stop an angry rampage and is glad this one is at least somehow more reasonable than rest of the alpha population.
"We are very sorry, sir" he apologizes again, just to make sure "I promise you this will never happen again"
The alpha nods absently and, to Kurt's surprise; holds the back of his neck with his free hand. The hold is firm and Kurt feels his legs weakening at the touch. He's not used to this; Blaine is a beta and while he's very satisfied with his boyfriend, he used to dream of this as a kid; of firm, big, alpha hands, the dominance and the imprinting. Of mating, of meeting some stranger and just knowing that he's the one.
He always knew that Blaine's and his relationship couldn't work on the long shot, not really. Blaine was a beta and while Kurt really loved him, he also knew that, as an omega, he would, sooner than later; find his alpha.
At first, he thought it was Sebastian, he surely felt a spark with the young alpha when he found the snarky little meerkat hitting at his boyfriend. But no, Sebastian wasn't nearly dominant enough, not really, he was just a pup, childish and if Kurt ever submitted to someone; it would be to someone who actually knew how to handle him.
And this alpha, he knows.
Kurt mewls and bares his neck, allowing the alpha to bury his face on his neck, to grind his face with the back of his neck and his chin with his shoulder. He moans at the feeling of the alpha's warm breath on his ear and urges his face to press harder on his skin by burying his long fingers in his soon to be mate's soft, short, brunette hair.
The taller boy growls and licks his collarbone before biting in his neck. Kurt should be ashamed, because there's an entire crowd witnessing his marking, but he can only feel pride and smugness, because this alpha is going to be his.
