This is gonna be a bit of a mix of Dom/Sub, Wolf Pack AU (but no actual wolves) and ABO. Essentially it has the sex aspects of dom/sub, with the pack bond dynamics of Wolf AU and the heat/rut stuff (probably) of ABO. Rated E, will defo get kinky, but also you can probably enjoy as a Porn with Plot and skip the porn if that ain't your thing.

May had waited a long time to find her pack. She had been born an Alpha; her mother had been so proud. She had assumed she'd find all her mates in her early-20s.

By the time she was 25 she had set her sights on SHIELD, aiming to utilise her natural gift of leadership, regardless of her unmated status. It wasn't uncommon for packs to remain uncomplete for many years, as mates were born, or circumstances changed. Although it was hard when many of her friends had already found their pack. Her fellow Academy graduate, Phil Coulson, was an Omega who had found his Beta early on. Clint Barton. As Coulson rose through the ranks, they found their other Beta, Tony Stark, and against all plausible odds, Steve Rogers was their Alpha.

Not everyone was destined for a pack, most people were assigned one life partner. May was sometimes jealous of them, it would have made her life far easier.

She had found Maria Hill first, at age 30. A spunky academy cadet, barely 20 years old and not yet legal to drink. She was her Beta, although determined to prove she could be just as capable as any Alpha. May had fallen in love from their first meeting. Her mother thought she indulged Maria too much, allowed her a little more wiggle room than she should.

As long as her mark was on Maria's neck, May was willing to give Fury's second in command all the authority she needed. Of course, what May's mother would never know was just how much Maria liked to let go of control in bed.

In retrospect, her time alone with Hill had been quite a light introduction to a pack, compared to the later chaos of the mix. Hill had found their second Beta, Bobbi, during a scout of the top academy recruits, a year later. The academy was also how they found their precious Omega, Jemma, a few years after that. Jemma had been barely shy of nineteen.

It was no wonder it took May so long to find them when they were all so bloody young.

They had settled into an easy rhythm: Hill became Deputy Director, May had retired from the field into training recruits, Jemma was still studying in the labs and Bobbi was climbing the ranks as a field agent.

Natasha was the wild card May had not been anticipating.

Natasha had just been assigned to Coulson after months of extensive assessment in a closed-off compound. May had been briefly stationed at the Hub to pay him a visit. Natasha had immediately attacked May, threatened by the presence of another Alpha. It took a long time to negotiate the pack dynamics, both Alphas fiercely dominant and possessive of their pack. The feud had ended when May allowed Nat to mark her, giving over ultimate authority to the younger woman. It wasn't on her neck, that had been May's condition, but that shimmering mark on her inner thigh was certainly Nat's favourite spot.

It took Phil Coulson's resurrection and a reassignment with Jemma, for May to finally find their other Omega.

May watched from the gantry as Coulson and Ward exited the SUV, dragging the hacker in tow. The girl stumbled out, bag over her head and hands tightly handcuffed behind her back. May bristled, her hackles rising as she spied Ward's firm grip on her bicep.

There was a sweet smell in air. May frowned, wondering if it might've been a lingering scent in the lab from Jemma.

Ward manhandled the hacker up the ramp, and the scent drifted over to May. Her nostrils flared at the scent of daisies, cheap perfume and the undeniable cinnamon scent that marked her as one of her own. An Omega. The girl tripped up the ramp and Ward yanked her harshly back to her feet. May growled a warning, the pair stood still in alarm, the girl tensing and turning her head underneath the bag to find the source of the noise.

"Let go of her," May ordered sharply, making her way down the spiral steps towards them. The girl stumbled back from her, Ward frowned and didn't move his hand.

"She's an active suspect," Ward said defensively.

"I know she is," May barked, "but she's also my Omega so I suggest you unhand her now."

May heard the girl's sharp intake of breath, muffled from under the bag. Ward raised his eyebrows in surprise but let go of her mate and held his arms up in surrender as he backpedalled. The girl shuffled backwards away from May as she reached out to grab her, not making it far before May had her own steady grip on her arms.

She didn't relax like most Omega's would, she tensed up more and tried to move out of May's lenient grip. May glanced over her outfit – purple shirt, black jeans, impractical boots and at least three necklaces. Certainly not a threat, and certainly someone who cared about fashion far more than May.

'Tense shoulders, she's defensive' Bobbi's voice filtered into her head, as she saw through May's eyes 'Cheap necklaces. Shirt's faded in the wash, not been ironed. She's young. Living alone, maybe. Not much money.'

"My eyes are up here," the girl snarked, muffled by the bag.

"Quiet," Ward snapped. May shot him an unamused eyebrow, he had the good sense to back down.

May didn't entertain the new Omega with a reply, simply pulled her forwards and through the lab. Fitz and Simmons were out checking the crime scene. Coulson and Ward followed them as they navigated through the bus, the girl deliberately dragging her feet.

May unlocked the door to the Cage, leading her inside and easing her down onto the metal chair. She immediately tried to get back onto her feet, so May pushed her back down and gently locked her handcuffs to the metal bar instead of behind her back.

May could tell she was nervous, despite the attitude, by the way her chest rose and the fear pheromones pouring off her. She shot Coulson and Ward a pointed look. Coulson dismissed Ward but remained in the room.

"I'll be supervising this interrogation," he said to her, "You need a second pair of eyes."

May almost scoffed that she had five pairs of eyes now, but let it slide. She turned to the girl, taking the bag off her head. She was young, about as young as Jemma, May reckoned. Big wide brown eyes and lips coated in an alluring gloss.

'Pretty,' Bobbi purred, 'I was right, definitely young'.

Her otherwise perfectly curled hair was mussed up by the bag, and May had to resist reaching out to fix it, reminding herself that this was an active investigation.

If the hacker was affected by the sight of May, she didn't let it show. She leant back, a challenging glint in her eyes as she locked her hands together casually on the table, staring May right in the eyes. May twitched, she couldn't help it at the dominant posturing from the submissive. She was trouble alright.

"Alright," Coulson said, sensing the tension in the room. The girl didn't even flicker her eyes over to him, just held May's gaze, "Let's start easy, what's your name?"

The girl licked her lips and smiled pleasantly, "Cathy."

May bristled. A lie.

"You're lying," she accused.

"What's your name?" the girl snapped back, addressing May and ignoring Coulson, "I like to know who my kidnappers are."

"Agent May," May replied evenly, "This is Agent Coulson. And your name is not Cathy."

May saw the annoyed clench of the hackers' jaw, but she simply shrugged her shoulders and traced imaginary lines with her finger on the metal desk. She was acting like she was any old Beta, or even an Alpha. May narrowed her eyes.

"Tell the truth," May ordered in her Alpha voice, urging the Omega to listen, "We're just trying to prevent an accident from happening."

Skye tensed, the strict command rolling over her, because of course the universe had to assign her an Alpha who was part of the shady organisation interrogating her. It wasn't fair.

Skye glared back, feeling the instinct to obey tight in her chest, tingling at the back of her neck, almost as though Agent May had a hand physically wrapped around her scruff. Skye fought it; she didn't need to obey. She didn't owe this woman anything. She was stronger than her instincts, even if she had never in her life felt so compelled.

Skye cursed her designation and curled her lip into a snarl as she glared back harder. Stupid Alpha, stupid Omega instincts.

May narrowed her eyes and placed her hands on the desk next to Skye's, towering over her. Skye jerked her hands away, the clang of the handcuffs ringing out against the metal bar.

"I will not repeat myself," May began, "What is your name?"

"Skye," Skye bit back easily, ignoring how nice it felt to roll the truth off her tongue.

May's nostrils flared. She titled her head, studying Skye. Her eyes felt like they could see into Skye's soul. Skye resisted the urge to squirm in her seat under her powerful gaze.

"Your other name," May asked.

"Mary Sue Poots," Skye answered in a light tone, a smirk quirked on her lip. May wasn't even asking the important questions. Mary Sue Poots was a nobody. It sounded even faker than the name Skye did.

"Good," May practically purred. Skye preened under the praise. The thought crossed her mind at how good it would feel to have 'good girl' roll off that tongue. To counter that terrifying thought, Skye rolled her eyes disrespectfully, leaning back in her chair. She took great pleasure in the way May's breathing hitched and her hands tightened their grip on the table.

Well then, if May was equally affected by her

"Want to know what side of the bed I sleep on too?" Skye teased in a sultry tone, leaning forward so her necklace shone in the light and drew attention to her cleavage. She bit her lip in a way she knew worked without fail.

May's hand twitched, but she maintained her composure. Agent Coulson looked away respectfully, May had no qualms dropping her eyes down to her cleavage, small smirk on her lip.

"I don't need to ask," May replied coolly, flicking her eyes back to Skye, "You'll be on my side of the bed. Underneath me."

Skye did her best to ignore the rush of lust at that sentence, and keep her face carefully blank, but she knew she had failed when May's nose twitched, and her face morphed into an infuriatingly knowing smirk.

"You seem awfully confident," Skye quipped before May could say anything, tapping a foot against the floor.

"I am," May replied, "Now stop stalling and answer my questions."

"But you haven't asked any," Skye answered with an innocent shrug of her shoulders.

May's jaw tightened. Skye raised a challenging eyebrow.

"We've been getting a little distracted," Coulson said, stepping in.

His questions were harmless enough, and Skye obliged, defending her integrity when they accused her of starting the explosion to draw Mike out. She told herself that she answered more honestly not because the Alpha was there – hip cocked, arms crossed, jaw tight - but because Coulson honestly seemed like a good guy. And Skye did not want to go to jail.

She supposed having a high-ranking Alpha in SHIELD might come in handy sometime soon, all she'd have to do is bat her eyelashes and she'd be able to get access to any document she liked. She smirked, yeah, it might not be so bad.

She followed May and Coulson out to the conference room, thankfully free of the handcuffs. The other guy, an Alpha called Ward, seemed a little upset by her walking free, but he said nothing. He must know that May wouldn't just let her go. Alpha's never just let things go. It was a pain in the ass.

"Oh!" a girl exclaimed, stopping in her stride as she caught sight of Skye in the conference room. May put a possessive but reassuring hand on Skye's shoulder as the pretty girl's face lit up warmly, "Hello."

Skye was already reeling from the revelation of the Alpha, she didn't think she was ready to meet anyone else, but here she was – a cute British girl whose body language screamed 'Omega!'. She smelt like May. Skye frowned, May never told her how many of them there were.

"This is Jemma Simmons," May introduced them, "Jemma, this is Skye."

Simmons waved shyly and Skye went to move forward confidently, determined to quickly establish herself. May, no doubt sensing Skye's intent to assert herself over the other Omega, tugged her back. The hand on her shoulder keeping her in place and forcing Simmons to be the one to approach. Skye would have protested against May, if not for the cautious eyes of Coulson and Ward or the thinly veiled threats by which she was allowed to be out of the cell at all.

When Jemma moved closer Skye noticed the four shimmering silver mating marks patterning her neck. Four! Four were dominant above her. That was…that was far too many.

Jemma stuck her hand out for a handshake. Skye took it confidently, aware of May breathing down her neck. Jemma's hand was smooth and well-manicured, and she had a very pleasant smile. She seemed every bit the prim and proper Omega, as she dropped the handshake and willingly held May's proffered hand. Skye almost rolled her eyes, trust her to get stuck with a T-1000 Alpha and a fellow little Miss Perfect Omega. No wonder May was such a hard ass.

Skye sighed. At least the packmates she had met so far were all gorgeous, bonding wouldn't be too much of a chore. In fact, she could imagine Jemma bent over, May behind her…

"Skye!" May snapped, "Focus."

Skye was startled, could May hear her thoughts already? She didn't think that happened until they were properly mated. All eyes were on her, so she cleared her throat.

"Uh, yeah?"

"Mike Peterson?" Coulson re-iterated, "You said you got ID?"

"Oh, right."

Skye gave them what she had, but they needed to get to her van for the sound recordings of the building. Of course, Agent May was the one who volunteered to drive.

An awkward silence settled over them in the SUV. Skye tried to take short breaths, not letting herself breathe in May's intoxicating scent too deeply. It smelt like home, or what Skye reckoned home smelled like to someone who had one. Warm, comforting, like snuggling by a fire.

She stared out the window as the city flew by, it wasn't necessary to give directions, they already knew where her van was. The air buzzed with an unacknowledged energy, and Skye found her gaze unconsciously drawn back to May. Her instincts wanted her to manoeuvre over the gearshift and climb into May's lap. It would calm the anxiety rippling around her body. She chewed her lip, her leg bouncing uncontrollably with the nervous energy.

May was breathing deeply, measured, her face calm as she concentrated on the road. She had gorgeous silky hair, smooth skin, strong hands that gripped the steering wheel –

"See something you like?" May said, eyes not moving from the road.

Skye cleared her throat and turned her attention back to the city. The car rolled to a stop at a red light. A couple walked by what was clearly a female Alpha with her arms around her Omega as they laughed at some joke.

A hand was suddenly on her knee. Skye jumped in surprise, as May's warm hand stilled the jiggling limb. Skye immediately felt more settled, which slightly alarmed her, even if her body weren't feeling anxious anymore.

"You don't want an Alpha," May stated. Skye couldn't tell if she was challenging Skye to refuse or simply stating what was fact.

"Not really."

"You don't want any of the pack," May continued, "There are three more you've never met. You don't even feel curious about them?"

"Not really," Skye repeated, even though that was a lie and they both knew it. She was curious.

"So, you plan to ignore us," May stated again, "Pretend your designation doesn't exist."

Skye didn't deny it. It had been her first thought.

May squeezed her knee gently, before swiftly moving her hand to the gearshift as the lights changed to green. Skye's shoulders slumped, heart feeling heavy at the rejection she felt with the loss of the hand.

"Okay," May said simply, "Whenever you're ready."

She kept up a stubborn silence but May made no attempts to break it. They soon reached her van, Skye scrambling out of the SUV as fast as she could, grateful for a breath of fresh air that wasn't May. Her nose wrinkled immediately, 'fresh' might have been an optimistic term for the smell of the alley.

She saw May's disapproving survey of the alley and her van, and Skye felt herself become protective of her home. She picked the lock on the side door easily. May shot her a raised eyebrow.

"What?" Skye said defensively, "It's not like you let me take my car keys with me when you kidnapped me."

She could sense May's strong criticism of the state of her living, as she rummaged through her belongings, finding some cables to start up her router again. May crossed her arms, peeking into the mess. Skye wanted to snap at her for being judgemental but didn't want to prove she cared about her opinion.

"This isn't safe," May finally said, voice surprisingly soft.

Skye scowled at her, "You try running away with $300 at 17."

May's jaw tightened in possessive anger and her fingers flexed as though she was fighting the urge to grab Skye. Skye knew the anger was directed at the situation, but still resented May for it. She deliberately took her time to spite May, firing up her laptop to check the sound files and send them to Fitz.

She made sure to tuck her SD card into her bra, before turning to May, "That should do it."

But then her Alpha was knocked out by Mike Peterson, and suddenly she was being kidnapped again.

May was livid. Mike had Skye and he was recklessly leading her mate and even his child into danger. He could explode any moment. She had just got the stubborn, infuriating hacker, she wasn't going to let her die.

She mentally blocked herself from her mates, they were usually too busy anyway to lurk in her mind, but she didn't want the distraction.

It was a good thing Skye was street smart, May was proud as she kicked a guy in the nuts and found her escape. May was caught by a thug, had to fight her way out – easily, but she lost sight of Skye. She followed the sweet scent, leading her up to the roof where Mike had her arm in a death grip.

She saw in slow motion as the fake cop took a shot at Mike. He pushed Skye away, she fell to the floor – thankfully out of harm's way. May was sprinting, but too far from the cop who shot again. Mike keeled over the railing with the force, but May couldn't look to see if he'd survived as the cop reloaded and pointed the gun at Skye.

May swept his legs out from under him, wrestling the gun to the ground before knocking him out with a swift punch. She checked he was out, before looking up to Skye, shaking the stray hair from her eyes.

Skye looked ruffled, out of breath and a little scared. When they caught eyes, she had a little quirk to her lip as she looked her up and down, almost as though she were checking her out. Was she turned on by that?

Skye was still staring at May in awe as she offered her a hand to stand up. Skye took her head without protest and May pulled her up, feeling the fast jump of Skye's pulse under hand. It was faint, they hadn't bonded yet, but May could swear she felt attraction from her. She must be more of an Omega than she wanted to admit if seeing May fight turned her on.

May pressed a brief kiss to Skye's temple, one that left a lingering pleasant tingling on Skye's skin even as she grabbed her hand and pulled her back into danger.

It had not been a surprise to anyone on the team when Coulson offered Skye a position of the plane. May was her Alpha, Jemma was her Omega, and she had enough skill to stand on her own two feet in the team. The entire rest of her pack were ranking members of SHIELD. It made sense.

Ward wasn't terribly happy, feeling that Skye was being given mate-privilege, but Coulson was quick to assure him that if she crossed a line, they'd happily send her to live with the more than capable supervising eyes of Maria Hill or Natasha Romanoff. There wasn't much Skye could do wrong under those watchful eyes.

Skye was not surprised either. She wasn't particularly happy, but she knew the deal. Join SHIELD and be with your mates, or don't join SHIELD and be with your mates you've never met but with less fun things to do and no freedom. It was an easy choice. Besides, SHIELD was exciting, had the answers she wanted, and she knew she was damn good at her job.

So, she packed up her van, wondering if she'll ever see it again.

"Would you like some help?" Jemma asked timidly, stood with her hands clasped together nervously as Skye shoved clothes into a bag.

Skye looked up; she would usually say no, not wanting anyone else to be touching her few precious personal belongings but upsetting Jemma – who so far had been nothing but kind to her – felt wrong.

"Sure," Skye said brightly, smiling at the other Omega. She could feel an easy camaraderie with the other female genius on the plane, someone who was also naïve but wanted a sense of adventure. Someone who did not have any desire to control her every move.

Jemma's face broke into a toothy smile, climbing into the van next to her. There wasn't a whole lot of space, but Jemma made it work.

"This is nice," Jemma commented, picking up her hula girl from the dash.

"Got it from the car dealer when I bought this piece of junk," Skye said, "I know it's tacky, but it's been through a lot with me."

"Throw or Keep?"

"Keep."

Jemma placed it carefully into the cardboard box, with the same organised care she had shown all the other items in there. There weren't many, but Skye was pleased Jemma treated them all as though they were important, even if they had little real value.

It went much quicker together, Skye sacrificing half of the computer junk in favour of a few USB sticks and her laptop. SHIELD could have the servers; they were patchy at best anyway. She had managed to find all her scattered clothes and put them into a pile, whilst Jemma had quietly re-folded each item to fit them into her duffle.

Jemma's eyebrows rose and her eyes shone teasingly when handling some of Skye's lingerie, to which Skye put a finger to her lips and threw her a wink. Skye was just finished chucking the duffle out the side of the van, much to Jemma's chagrin, when Fitz appeared looking as excited as ever.

"May says she needs you," Fitz told Jemma, "Something about Bobbi."

Jemma nodded, squeezing Skye's hand once before leaving to find May. Fitz turned to her with a grin as he took the box from her arms and hurried her up the ramp.

"I'm glad to have you on board," Fitz said, as he led the way up the spiral staircase to the upper level, "Always good to have another Omega with us, and of course any mate of Jemma's is a friend of mine."

He led her through the swish living quarters she'd already seen, opening out to a common area surrounded by little pod-like bunks.

"Simmons doesn't have a bunk," Fitz babbled, "She shares with May and I'm sure you'll be the same since…" he trailed off at Skye's unamused glare, "Well I suppose, only if you want to that is. Although hers is bigger, and comfier or so I'm told. Since she's the pilot and all."

Skye spied an open empty bunk and dumped her bags on top, "This is fine."

Fitz wiped his palms on his jeans nervously.

"Who's Bobbi?" Skye asked, curious.

"Oh, she's a Level 7 Field Agent," Fitz answered, "She's really cool. She's with Maria Hill right now, Natasha had to leave for an undercover mission."

"And who's Natasha?" Skye asked with a frown. So many names to remember.

"You don't know?" Fitz exclaimed, looking thoroughly surprised.

Skye shook her head with a frown.

"Black Widow? She's your other Alpha?"

Did Fitz just say Black Widow? As in THE sexiest member of the Avengers and 'her Alpha' in one sentence? Surely not.

"Black Widow is my what!?"
