Klance One - Shots || DISCONTINUED

6. Mate (Smut/Fluff)

Alpha/Omega AU! This will also be a smut! Please feel free to skip this chapter if smut isn't your cup of tea!

Keith is the omega of the story and Lance is the Alpha!

Keith groans as he tries to get out of his clothes as quickly as possible,  and there was sweat going down his face. Keith can't help but curse to himself for forgetting that he himself was an omega and that he had a heat. He was blaming himself for not having suppressants and birth control on him at all times like his father taught him to.

Beforehand he asked Allura to lock his doors so no one can enter, she was confused at first but Keith said he'll have Lance to explain for him, which he is currently doing.

"Why did Keith just ask me to lock him in his room?" Lance's eyes widen and hits himself for forgetting. "Keith is in his heat, his pheromones will get stronger and irritate the other alphas that aren't bonded." Lance goes towards Shiro and tells him to beware that Keith went into his heat. Shiro nods and gives Lance a saddened look, knowing he'll be having a tiring few days.

"You need to lock me and Keith in his room for a couple days." Lance says with embarrassments, she just looks at him with confusion, "Keith and I will unable to do training or be part of missions." She gives him another confused look, "Look, both Keith and I are going to be physically unable to work." Lance turns to Hunk, who's a Beta, and gives him a look, "Hunk can you please tell her, I have to go help Keith now." Hunk nods with sympathetic look and Lance runs off.

Lance gets hit with a huge wave of an aroma that he can't get enough of. He knocks on the door and the door opens, Lance can't help but feel aroused at the sight before him. Keith gives him a look of hunger, Lance undresses while making his way towards Keith, who has legs spread for his alpha. "L-Lance..." Keith whimpers, and Lance just comforts him by caressing Keith's torso, "Shh baby... I know..." Lance leans down and kisses Keith.

Keith hungrily kisses back and aches for Lance to touch him; Lance just smiles into the kiss and treat Keith like a flower, gentle. He can't go full alpha on him since they're in space. Lance pulls away from the kiss and pulls away, Keith whimpers and tries to get Lance to touch him, "Keith, baby..." Lance moves down from Keith's torso to his hole. "I have to be careful okay... I'm assuming you don't have birth control do you?" Lance asks gently, Keith just moans in relief as Lance inserts two fingers. Keith shakes his head 'no' to Lance's question and goes down onto Lance's fingers.

Keith moans out loud as Lance moves his fingers, he grabs a fist full of sheets and squirms underneath Lance. "L-Lance!" Keith fidgets and twitches with each movement. Lance smiles at his mate's actions. "I know baby..." Lance adds the third finger and Keith's eyes roll back a little bit.

"A-Alpha..." Keith whimpers and Lance looses a little bit of control. "I n-need you..." Keith pulls Lance down for a kiss, as soon Lance pulls away from the kiss Keith groans in annoyance that Lance hasn't started fucking him yet. Lance adds a third finger and Keith hides his face from Lance as he moans, Lance tries thrusting a little harder, which caused Keith to scream in ecstasy. "L-Lance!" Lance is yet again loosing control, he pulls his fingers out and wipes them on the sheet and aligns himself at Keith's hole.

In Keith's mind it's just, 'yes, yes, yes'.  Keith whimpers as Lance slowly thrusts into Keith. Lance growls and hides his face in Keith's neck. "Oh god..." Lance start leaving love bites all over his neck, his tongue constantly running across his neck. Keith's finger Lance through Lance's short hair and tugs at it. Lance growls again which made Keith hot and whimpered in response.

His omega instincts is kicking in, and making him submit to his Alpha.

"F-Fuck-" Lance says loudly away from Keith's ear, Keith looks at Lance with glassy eyes and rosy cheeks, "What's w-wrong?" Keith moans and Lance digs his fingers into the mattress, "My rut is kicking in."
