#Sheith Omegaverse.
Omega Shiro and Omega Keith had always been happy together. Their relationship wasn't 'conventional' by earth standards, but for Galra it was quite normal for Omegas to live as a couple. Sometimes they chose an Alpha to offer heat aid.

#Sheith
So far Shiro and Keith hadn't needed an Alpha to help them. They knew each other well enough to comfort each other during heat. They didn't like the idea of some dominant Alpha setting foot in their little love nest. They could manage just fine on their own.

#Sheith
Being Galra meant Keith had a different kind of scent & Shiro couldn't get enough of the potent odour. He would take charge of building their big nest & line it with Keith's worn clothes. He loved to roll around naked, covering his body with the sumptuous Omega perfume.

#Sheith
Another Galra trait that pleased Shiro was Keith's dick. While modest & small when flaccid, it tripled in size when he became aroused. The shaft was thick and ribbed with a soft violet hue leading up to a darker purple head. Shiro loved it, he could stare at it for hours.

#Sheith
The other detail about Galra Omega cocks was that they could also inflate the base to resemble a knot. This had evolved from years of Omegas having to manage without their Alphas as they went off to fight in battles. The Omegas learnt how to help each other during heat.

#Sheith
As soon as Shiro's heat began he would crawl into their nest & present himself to Keith, nuzzling & whining for his 'knot'. Keith happily obliged his mate, fucking him good & deep before wedging his Omega knot inside Shiro's slick hole. Keith loved making his mate happy.

#Sheith
Similarly Shiro helped Keith with his heat. As he didn't have a 'knot' he wore a specially designed bulbous cockring. It worked perfectly as a knot substitute. Keith would ride on top of the big Omega, purring & begging to be filled.
It worked for them.
They were happy.

#Sheith
Even though Galran Omegas were self-sufficient and practical, there was still one thing they couldn't do.
Breed.
For that they still needed Alpha seed. Traditionally a pair of Omegas would both mate with a carefully selected Alpha, increasing the chances of a baby.

#Sheith
Human Omegas like Shiro could also be impregnated by a Beta. Galra didn't have Betas, so Keith had no idea if he could also mate with one. He assumed having a human father meant he probably could.
Neither of them wanted to mate with an Alpha. They knew it could get rough.

#Sheith
They were both strong enough to take it, but neither had experience with Alphas. They'd seen other Omegas covered in scratches & bites, unable to walk properly for days. This turned them off, made them feel safe & content they had each other. Yet still they wanted a baby.

#Sheith
After talking it through they decided to try and breed with a Beta. They both had someone in mind, but felt awkward raising the matter. He would be excellent parent material and they felt he might be open to their suggestion, being an easy-going type of guy.

#Sheith a/b/o cont.
Beta Hunk had always prided himself on his abilities as a baker. He loved creating delicious flavour combos, and knowing people enjoyed his wares gave him a warm glow in his heart.
Something else that ignited his heart was seeing big handsome Omega Shiro.

#Sheith + #hunk
He knew Shiro and Keith were together, but a tiny spark in his core always burned brightly for his crush. He never thought he stood any kind of chance to be anything more than just a friend. He'd long given up on any romantic notions, but nobody else came close.

#Sheith #Hunk
At no point could Hunk ever have imagined what would happen next.
He'd spent a busy morning working in his bakery when Keith and Shiro casually strolled in. After a few well-aimed jokes about having 'buns in ovens', they invited Hunk for dinner at their place.

#Sheith #hunk
They told him they had a proposition for him and it would mean a great deal to them if he accepted. Hunk agreed to come over at 7pm. He spent the rest of the day feeling curious and a little anxious, but excited about spending an evening in Shiro's company.

#Sheith #hunk
"You want me to what?"
"We'd like you to breed us."
"Oh boy, you guys know I'm not an Alpha right?"
"Yes, that's the whole point. We want to mate with a Beta, so who better than our favourite friend?"
"Well, I'm SO flattered, but I-"
"Fantastic! Thank you so much!"

#Sheith #Hunk
And that's how it happened. Hunk found himself quite literally head-hunted by two broody Omegas. The idea that his one true crush wanted to have his baby felt like a dream come true. He got so caught up in his thoughts he almost forgot about Keith.
/Breed 'us'/
Oh.

#Sheith #Hunk
As luck would have it, Keith fell into a heat a week later. It came on suddenly, so Shiro hurriedly contacted Hunk.
The Beta baker mistakenly read Shiro's message to mean he was the one in need. His heart raced thinking this was the moment he'd always longed for.

#Sheith #Hunk
With a big smile Hunk arrived at the Omegas' home, but before he got chance to knock, Shiro flung open the door & dragged him inside.
The burly baker couldn't hide his delight at being manhandled by the big Omega, but his joy soon waned when he saw Keith presenting.

#Sheith #Hunk
Hunk swallowed hard. He'd made a promise and now he needed to step up and deliver the goods. He glanced at Shiro and saw the hopeful look in his eyes.
"Ok. So, I guess this is it, Keith is ready...oh eh, don't worry if he starts growling, it's just a Galra thing."

#Sheith #Hunk
Shiro hesitated and pulled Hunk in for a hug, squeezing him tight. The smitten Beta closed his eyes, the warm embrace turning him on. He felt sure he'd have no trouble getting hard wrapped in Shiro's arms, but the big Omega stood back and handed him his cockring.

#Sheith #Hunk
"You need to wear this, it helps with the mating process. When you're ready to come, lock yourself inside, it stops the seed from dripping out. Keith will need it...things get a little messy." He stroked Hunk's arms and chest. "You need more of my scent on you."

#Sheith #Hunk
Keith squirmed and purred while Shiro prepped Hunk.
"Wait? You're not staying? I thought y-you wanted me to ..eh..both of you?" Hunk stammered.
/Please stay/
"No, I'm not in heat. I'll only be a distraction. You'll be fine. Isn't this exciting?"
Hunk grimaced.
/no/

#Sheith #Hunk
Shiro closed the bedroom door, leaving Hunk alone with Keith. The heat-struck Omega writhed & moaned, trying to claw all of Shiro's clothes around him in their nest. He glared at Hunk, his eyes fixed on his crotch. The kind Beta smiled nervously.
/Please be gentle/

#Sheith #Hunk
This wasn't what he'd expected. He thought Shiro would be there too.
/Ok calm down, this is Keith, your friend, he's great/
But the feral Omega before him didn't resemble the Keith he knew. Hunk shook his head, he needed to focus.
/He's just an Omega, nothing weird/

#Sheith #Hunk
"Hey Keith, don't worry, I'm here. Would you like me to join you in your nest?" Hunk spoke in a calm voice, trying to pacify the snarling Omega.
Slowly, he undressed, but Keith had other plans and crawled out of the nest to circle Hunk in the middle of the room.

#Sheith #Hunk
The sweet-natured Beta felt like prey being stalked by a predator. He tried to relax & told himself to just go with it, allow Keith to sniff out Shiro's scent on his body.
/It's fine...holy shit!/
He took one look at Keith's Galra cock and felt his own disappear.

#Sheith #Hunk
/Where the fuck did that come from? It's huge...and purple!/
Keith growled & hissed as he pushed Hunk into the nest. It felt warm & smelt musty, strangely arousing. Hunk realised it must be Shiro's scent. Keith straddled him, the Galra cock bouncing off his belly.

#Sheith #Hunk
Hunk thought Shiro's scent would sedate Keith, make him more pliant. Instead, it seemed to drive him wild. He rubbed himself all over Hunk's torso, twisting and grinding, soaking his remaining clothes with slick.
"Ahh..need..knot me..fill me," Keith whined.

#Sheith #Hunk
/Shit, the cockring..I need to put it on/
Curving his big hands round Keith's slender waist, he gently moved him on his back. Hunk wriggled out of his pants and boxers and stripped away his slick-covered t-shirt. He looked down at his too soft dick & sighed.
/Oh no/

#Sheith #Hunk
/Please don't let me down.. don't let Shiro down...ah lovely Shiro/
Just thinking about the big Omega gave Hunk a little jolt in his groin.
Keith wrapped his legs round the Beta's sturdy body, his untamed edge softening into something more fragile and needy.

#Sheith #Hunk
"Please, give me what I need. Take me, breed me." Keith's eyes filled with tears and Hunk saw his desperation.
He moved over Keith's smaller frame, caging him with his big arms. Keith looked radiant, his violet eyes glowing.
The Beta found his confidence.

#Sheith #Hunk
He needed to accept the Galra cock, not feel intimidated. He reached down and touched the purple member. It felt surprisingly soft, velvety almost. He stroked it, feeling the supple ribbed texture slide over his palm.
/This feels nice/
"Ah, g-good," Keith purred.

#Sheith #Hunk
"Yeah? You like that? Tell me what else you like." Hunk wanted to imagine all the stuff Shiro would do to make Keith happy. Picturing Shiro doing all manner of lewd things gave Hunk an instant boner.
He slipped the cockring on, smiling at it's rounded shape.

#Sheith #Hunk
/So this is what an Alpha knot must feel like/
Hunk settled between Keith's thighs, still paying attention to his cock. He marvelled how it increased in size.
/I bet Shiro loves it, I bet he sinks on top of this purple beauty and rides it all the way to heaven/

#Sheith #Hunk
Keith groaned, his hips rolling up, trying to connect with Hunk's heavy cock.
"Please, h-hold them together...like S-Shiro does..ah."
"Oh that's what you like? Does he make it feel good?" Hunk grinned, he loved hearing Shiro's name.
Keith whimpered, "Yes, so good."

#Sheith #Hunk
"Okay sweetheart, whatever you need."
What Keith needed was to come first, because it would help prepare him for Hunk's seed. The fresher the slick, the better the flow to his eggs.
Hunk took hold of both cocks and rubbed them together.
"Oh, that really is good."

#Sheith #Hunk
Galra cocks were very sensitive, capable of multiple orgasms in quick succession. Their design gave intense pleasure, as well as optimal functionality for breeding. Keith's heat heightened all his senses. Feeling their cocks slide together pushed him over the edge.

#Sheith #Hunk
"Ah..yes ahhh," Keith cried. "Now I need you to come inside me...Please." He lifted his legs up over his cum-covered tummy, presenting his hole, eager and twitching, dripping with slick.
"Breed me Beta, give me a baby." Keith's eyes seemed to light up with desire.

#Sheith #Hunk
Hunk didn't need telling twice. Lining his thick member up with Keith's entrance, he eased himself in. The slick made Keith's insides feel hot & wet, perfect for receiving fresh potent seed. The Omega clamped on to Hunk's shoulders, digging his nails into the flesh.

#Sheith #Hunk
"Ah yessss...good, like my Shiro, fuck me harder, come inside me, knot me," Keith growled, his walls contracting, almost sucking the Beta inside. Hunk had never felt anything so forceful and it didn't take much for him to feel a familiar wave of fluttering pleasure.

#Sheith #Hunk
He sped up his thrusts, faster with every push. Through the mess of Keith's slick, Hunk fucked them both to completion. He felt his seed shoot out, filling the Omega. In his mind he thought only one thing.
/Shiro/
"Ahh Shiro!" Keith hollered, making Hunk smile.

Sleep time!
Hunk indulging his crush is all I need right now. Both he and Keith dreaming of lovely Shiro is totally valid and it's only going to get better 😏💋🔥😘🍑🍆🍼
