Kosmo laid down in the sand and chewed on an old bone he had found. He heard some scuttling in the sand and picked his head up. His pupils dilated when he saw a sandy colored, unsuspecting rabbit pop up out of the hole and immediately got into position to pounce on it. Keith had been a bit forgetful lately with his feeding schedule, and it was all because of that pretty princess that's been living with them!

Whenever it was his feeding time he'd teleport in front of his bowl, ready to be fed, but sometimes his master would never come down, and he'd hear him screaming from upstairs. So he'd teleport up into his room and find him rolling around in the sheets with the princess.

Sometimes they were wearing clothes, sometimes they were naked. And one time his master was tied up and the princess was playing with his dangly bits and putting them in her mouth or sitting on them. He wasn't too sure what those bits were, but it made his master scream whenever she did anything to them so he'd bark to try to stop her but then his master would see him and remember that he has to feed him and the princess would hastily untie him so he could take care of his pet.

But now he had found his own meal and he was ready to kill the rabbit when suddenly he heard the princess scream just as he was about to pounce on it. The rabbit ran back into the hole and he growled in annoyance and turned to the princess. Then he tilted his head in confusion when he saw what she was wearing.

She wore a pink bikini top with polka dots that showed all of her cleavage, only held together by thin strings and she wore the tiniest denim shorts he had ever seen on a person. But the strangest thing to him was that she was pointing at him and screaming.

"Oh no! A wild animal! And I'm completely defenseless to fight it! If only there was someone here who could help me!" Allura exclaims dramatically.

"Don't worry darlin' I'll save you!" Keith says heroically from behind his wolf, with a Southern accent.

He lands in front of Kosmo, shirtless with his knife out and pointed at the wolf.

"Stay away from her you filthy vermin!" Keith shouts at him.

Kosmo's eyes get big and he whines and looks upset. Keith immediately breaks character. He knelt down beside Kosmo and hugged him.

"Oh my gosh boy I'm so sorry I didn't mean that you're my best friend and I love you-" He rambled until Allura cleared her throat and placed her hands on her hips, frowning at him.

He mouthed an apology to her then cleared his throat and stood back up in front of his wolf.

"Okay I'm going to kill you now to protect this little lady!" Keith declares and points his knife at Kosmo.

"Play dead." He says through gritted teeth.

Kosmo barks and happily wags his tail before flopping over onto the sand on his back with his belly up in the air and his tongue hanging out.

"Awww..." Allura says and smiles at the wolf. "Oh Keith I don't think this is working..."

Keith sighed and sheathed his knife.

"I know I'm sorry 'Lura. You know I'm a horrible actor." Keith apologizes.

"That's not it." Allura says. "It's just that we can't seem to stay in character."

"Why do we even have to have characters?" Keith asks. "If you're horny why don't we just bang? I can yank off those daisy dukes and fuck you right here in the desert if you want."

"As divine as that sounds, I've just been a little bit bored lately..." Allura says. "I just thought maybe we could come up with some sexy scenarios and act them out. Add some drama and other sexy scenarios."

"Well I thought the scenario we just had set up was pretty sexy." Keith argues. "I know how much you like it when I talk with my accent." He says in it and winks.

"I know darling but be honest with me, is any of this working for you?" Allura asks and twirls a lock of her hair.

Keith looked her up and down and licked his lips before cupping himself.

"Well that outfit definitely works for me..." He rasps and starts to palm himself as he walks over to Allura who was now smirking and doing a visual assessment of her lover as well.

"Really? But I'm hardly wearing anything." She teases.

"Yeah, that's why I like it." Keith tells her.

She hums softly as his calloused hands touch her warm mocha skin...eyes glued to her cleavage.

"Let's get you back to our place before some lucky hikers see you like this." He says.

He gives her ass a playful smack, making her gasp in mock surprise before smiling and unbuckling his belt as they stumbled backwards across the sand towards his house, leaving a confused and still hungry Kosmo behind in the sand.

Keith sat at the kitchen table in his senior BOM outfit, sharpening his blade with a stone while Allura scrolled through her data pad in her silk pink nightie top and matching shorts with bunny slippers.

"Find any good role-plays yet?" Keith asks.

"No. I've resorted to reading fan fiction for some juicy scenarios." Allura says.

"Oof. I'm not sure how I'd feel about acting out a scenario from something as cringey as that." Keith complains.

"It's not all cringey." Allura says. "There's a lot of stuff that's very well written. In fact, there's this one idea I've found that's got me feeling some kind of way..."

Keith arches an eyebrow at her and she passes him the data-pad. He blushed and looked up at her when he read the description.

"Alpha/Beta/Omega dynamics? Isn't that the thing that wolves have for mating?" Keith asks and pets Kosmo's head as he slept at his feet.

"Yes. But there are some people who write alternate universes where other species, mainly humans use this system for mating as well. They have scent glands and the alphas claim an omega as their mate and help them when they're in heat by knotting them and getting them pregnant-"

"Whoa you want me to get you pregnant?" Keith asks, eyes wide.

"Well...at some point yes but not right now, we're both far too busy for a child at the moment. But there's something extremely intimate about the thought of you putting your baby inside of me..." She sighs, giving Keith a seductive look.

His face was bright red and he could feel a tent forming in his suit from his erection.

"Claiming me as yours and no one else's..." She continues and he licks his lips.

"Yeah...yeah I like how that sounds." He says. "So how do you want to do this?"

Allura fixed up her tiara on her forehead and looked herself over in the mirror. She had a sexy nightie on and she wrapped her robe around herself to cover herself until the right moment. She walked over to the front door of the house and knocked on it.

"Princess, do you need something?" Keith asks from the other side of the door.

"Yes." Allura says and smiles. "I need some company. I'm so terribly lonely."

"The point of you being here is so that you have no company." Keith explains. "Your father sent you here to wait out your heat so that you don't attract any alphas who will try and claim you. You're alone for your own safety princess."

"Yes I'm aware." Allura groans. "But can't you just make this one exception. Please Keith. You're my most trusted guard, and I'm just so lonely."

Keith sighed and unlocked the door.

Allura squealed in delight at the sound of it unlocking and then ran over to the wall and stood there, happily awaiting Keith's entrance.

He stepped into the house, wearing his regular BOM suit instead of his Senior one and sniffed the air. Then his eyes widened and his hands trembled as he shut the door behind him.

"I shouldn't be here while you're in heat." Keith breathes and looks away from her. "It's not safe for you."

"Why?" Allura asked. "All of my guards are omegas. Including yourself aren't you?"

He sighs and looks around the room before his gaze lands back on Allura. Her eyes widen when she realizes...

"No. I'm an alpha." Keith says.

She licked her lips and shifted her weight.

"But you already knew that didn't you." Keith accuses and she giggles.

"I may have had a hunch." She says and takes off her robe.

Keith's breath hitched when she stuck her ass out towards him. She was presenting to him.

"Allura..." He gulped.

"Mate me Keith..." She moans. "Claim me, knot me, breed me! Please, I need it!"

"I'm only a guard. I'm not suitable enough to be your alpha." Keith says and takes deep breaths and looks up at the ceiling to keep from pouncing on her.

"I don't care about your title." She says and runs up to him and hugs him tight.

Keith took in a sharp inhale, pretending to have her scent overwhelm him.

"I love you Keith, I want you to be my alpha. I need you to claim me now so that I cannot be promised to another." Allura explains.

She gasped when she suddenly felt Keith's big, beefy hands grab her ass. He growled and began to grind against her and she whined.

Allura gasped as he tore away her nightie, leaving her naked before him except for her panties.

He licked his lips as he observed her form, shy but sexy, completely bare except for her panties but damn she was gorgeous he thought as he reached for her.

"Oh! Oh!" Allura gasped and moaned in surprise as she was suddenly lifted into the air and over Keith's shoulder.

"Oh Keith, I know you're in rut and physically you're so strong, but please...try and be gentle with me. At least in the beginning. It is my first time after all." Allura requests.

"As you wish Your Highness." Keith replies and opens the door to the master bedroom.

He threw her down on the bed so she was laying on her back and then he pushed her thighs open and licked his lips when he saw the wet spot forming on them. He reached down and nuzzled his face against her clothed folds and his pupils dilated as he took in the scent of her wetness and he licked her through the fabric, making her even wetter and whine even more, so he let his fangs grow out and he bit the cotton fabric in his teeth and smirked.

Allura gasped as Keith tore her panties from her then swiftly opened her legs wider to expose her pussy and he chuckled as he stared at it.

"Look at you, already soaking wet for me." He chastises. "Me, a simple half-breed guard is about to mate and breed the princess..."

Allura whined and rocked her hips towards him and he chuckled again and took off his gloves before reaching down and petting her pussy, making her whine then moan as he slid two fingers in her with ease and stretched and explored her sex.

"Oh yeah...you're ready to be bred." Keith says.

Allura grunted as Keith suddenly flipped her over onto her stomach and lifted her hips up in the air pushing her thighs apart to reveal her sex.

Keith made quick work of his belt, then began unzipping his fly, planning on pulling his pants off just enough to get his cock out. But then one look from Allura over her shoulder tells him otherwise.

"Keith...I want you naked..." She whines.

He licked his lips as he stuck his hands in his pants to pull himself out.

"You think you're the one that should be giving me orders right now?" He asks and pushes her back down to give it the perfect arch.

"I am your princess." She reminds him.

"You're also my omega." Keith reminds her. "You're in heat, and I'm your alpha." He growls.

Allura whined as he pulled her hips back and ran his shaft in-between her folds.

"So if you wanna get fucked, we're going to do things my way." He says and teases her by pressing his tip against her entrance.

She moans and clutches the sheets in her hands and arches her back further towards him, unaware that he had heeded part of her request and stripped himself of his suit.

"You ready?" He asks and holds her hips, pressing his tip back up against her entrance.

"Yes." Allura says and then screams as Keith plunges into her from behind.

"Fuck you're so wet." Keith groans and closes his eyes, taking in the feeling of being completely sheathed within her. "I was able to slide right into your tight little cunt."

He gives her ass a light smack before continuing to rock his hips against hers.

He fucked her roughly from behind, making her moan and whimper, teasing her clit just to make her clench around him and he closed his eyes and pretended to concentrate on forming a knot. He bit his lip then pulled out and flipped her onto her back, holding her legs open by pressing on her inner thighs before plunging back in.

"Oh do it Keith please!" Allura begs seductively and places her hands on his shoulders. "Knot me, breed me, claim me as your mate."

"Alright then." Keith smirks.

He kisses her lips gently and she giggles as he hooks his arms under her thighs and spreads her legs open wider as he sinks himself to the hilt inside her and she moans softly from the stretch.

"You asked for it." He breathes against her lips.

Allura shudders and smiles softly when she sees his eyes turn galra.

"Oh Keith..." Allura moaned seductively.

Keith smirked and licks his tongue across his fangs.

Then she furrowed her brows in confusion when she felt something pushing on her walls inside of her. She shifted a bit on the bed and looked down at where they were joined, thinking that she was just in a weird position but her walls kept getting stretched as if something was growing inside of- the realization hit her and Keith's smirk grew as her mouth gaped and her chest started heaving as her breaths got shallower from her discovery. He held her hips steady to keep her from writhing too much and hurting herself as she started to squirm underneath him.

"Keith...Keith! Can you actually- is this a- oh! oh...Oh!" She pants and moans as her walls stretch for him.

"Why so shocked? You said you wanted my knot." Keith drawls and rubs his thumbs on her sides in soothing circles.

"Yes but I didn't know you were actually an-" She mutters incredulously.

"Alpha." Keith finishes for her. "Yeah. I am."

Allura gulped and her eyes widened.

"It's a galra thing. My mom told me about it. But we tend to keep quiet about it so that way the people we conquered wouldn't see our omega soldiers and generals as weak or be able to use our sexual practices against us during the war." He explains.

Allura gasped at his response and her mouth gaped again as his knot stretched her tight walls even more as it swelled. Keith closed his eyes and furrowed his brow, clenching his jaw shut and grunting as he took in the pleasure of knotting his mate.

"Ah Keith!" She screamed. "It's too big it won't fit, take it out!"

"I can't..." Keith pants and Allura furrows her brows in confusion. "The point of having a knot is so that I can't pull out..."

He leaned over her and she gulped.

"You know that's what breeding means right?" He drawls.

She gasps as he thrusts into her roughly and places a hand on her lower belly, gently stroking it with one of his fingers.

"So that all my cum gets inside of you to get you knocked up with my baby." He whispers sweetly against her lips as he rubs her lower belly.

Allura smiled and felt a warmth spread through her at the thought of having a baby with Keith. They both wanted to have at least one child together and even though she knew it wouldn't happen now because she wasn't in her fertile period, the realization that it could happen if her fertile period lined up with one of his ruts had her feeling some kind of way.

Allura's eyes widened and she screamed as it got bigger and she spread her legs open wider so his knot had more room and Keith let out a deep exhale and his eyelids fluttered as his knot swelled to it's full girth.

"Oh! Oh! Oh!" She screamed over and over again as her cunt was stretched to it's limits to accommodate his knot.

"Keith! Oh...oh Keith..." She moaned and tossed and turned her head on the pillows.

"It's so big! I'm so stuffed!" She keens and moans again as her walls clench around his knot and he hisses before licking his lips.

"Yeah you are." He says and his lip curls up in a smile. "You're taking my knot so good. You're such a good girl and you have such a tight cunt. I'm gonna fuck it with my knot then fill it with my seed and get you knocked up!" He grunts and squeezes his eyes shut and clenches his jaw and pounds her into the mattress.

She screamed his name so loudly that she was sure the Garrison could hear it from their house as she came. Keith roared her name in response and added "Oh fuck yes!" As his hips stuttered and he held her hips flushed to his as he filled her with his cum.

Allura gasped and looked down at where they were joined, clenching the sheets from the feeling of getting flooded with all of his cum. There was so much of it. There would be quite a mess to clean up once he pulled out.

Keith's arms nearly buckled and he bent over her, his sweaty hair falling into his face and he panted and breathed heavily as he laid over her.

"How was that for you?" He asks and smirks.

"Perfect." She answers and kisses him.
