Spoiler for episode 1x12: Bad Wolf (Part 1), takes place during it

WARNING: I didn't read back over this, I just kind of wrote it today for no reason. There will be a second chapter but I can't promise a timeset.

"Then let's move it! Into the lift. Isolate the lift controls!" Jack barked at the employees, watching them bus off to find the guns. Rose disappeared with the sweet Hannah, both blonde heads bobbing past the TARDIS. Jack's heart was working overtime, his breath coming in short bursts. He leaned heavily on the console, palms digging into the siding.

The Daleks were moving and they were moving fast. Twenty-two minutes, that's all they had to prepare. Two employees with only the will to survive as their tools, a sweet brat, a companion, and the most brilliant man he'd ever known. But he wasn't really a man, was he? An alien, someone from another planet – another world. A world he knew nothing about, a world that was gone now.

The Doctor.

Jack felt his cheeks warm but he ignored it, he couldn't think like that right now. He needed to man up and get ready for the battle, he had no time to feed his little omega feelings. They were eating away at the back of his mind, stealing his nerves, plucking at his heart strings. The good Doctor had set off his hormones the moment he'd seen him, that first whiff of pheromones had filled his lungs with ache and his head with cotton. The day he'd boarded the TARDIS the Doctor had hugged him, that touch had been enough to set off his heat cycle. He'd hidden away in the TARDIS for days, the ship had kept him hidden from both Rose and the alien for the full length.

The TARDIS understood his problem and kept him out of sight, kept his smell hidden, well watered, and fed.

Captain Jake Harkness was an omega, a rare species in his 51st century world. In Rose's current time, alphas and omegas were the major set and their dynamic ruled strong. But in his time alphas were almost none and betas were the norm, leaving omegas to either pitiful existences in brothels or at the mercy of beta soap and a rough childhood. After his first heat he'd decided to live the life of a strong beta, refusing to ever acknowledge those weak omegas needs that set him into heat once every month. But those heats had all but disappeared, he hadn't had one in years. Not even his promiscuity had set off the cycle.

But one whiff of the Doctor and he was gone, lost in his own touch and biological needs. He'd spent three days with the Doctor's scent around him, staining his sheets and pillows and walls like paint. He'd rubbed himself raw and stuff himself full of his collapsible alpha-cock simulator, but nothing felt as good as a living, breathing alpha mounted on you.

But the Doctor wasn't an alpha, the Time Lords didn't have those sorts of dynamics. Just his people, his weak race of humans who couldn't quite let go of their old biology. You'd think they'd have died out by now, but as long as there was alpha there would be an omega there to spread their legs for him/her.

Jack took a deep breath and turned around, ready to face the Doctor for the last time. The man dropped his lump of wires on the floor, glaring at it like it had bitten him. Jack's steps were sure and quick, he couldn't make this more than a minute or he'd start crying or getting second thoughts or something else equally as stupid.

"Doctor" his voice didn't waver.

"Jack" the Doctor's grin was bright, a light in all this darkness.

"I guess this is the end" Jack wet his lips, catching a taste of the man's scent in the air "That means it's time for good-byes. You're not good with good-byes, right?"

"Nah, never have been" the older man shrugged "Too many in one lifetime. Trust me."

"And I'll just be another" his voice definitely did shake that time, but his smile was just as bright "Let me just say this, Doctor, you...you are worth fighting for."

"And you are trouble" the Doctor shoved his hands deep into the pockets of his coat "Almost destroying the human race with nanobots, bringing Margaret Blaine's little surf board onto the TARDIS, and who knows what else. You've nearly killed us all."

Jack started to lower his gaze when cool fingers grabbed his chin, forcing his head high, "But you did it brilliantly."

There was a tone in his voice, a note of something that Jack hadn't heard in years. Long dormant feelings began to stir to the surface, submissive urges to kneelspreadmoansuck and embarrassing thoughts of takemepossesmeloveme. He swore he saw the man's nostrils flare, swore he saw a gleam in his eyes that wasn't there before. He had to be wrong, there was no way this man was an alpha. Sure he had alpha tendencies, but Jack had been in the presence of top alphas before and even they hadn't brought the omega out in him.

/Stop/ he scolded himself, finding himself smiling and stepping back /He's not an alpha, and he's certainly not your alpha. Don't make a fool out of yourself, Jack, you're better than this. Think beta./

"I have to go" Jack could barely breathe, the sense of dread in the room growing "They'll be here soon. Goodbye, doctor."

The words were sour on his tongue but he forced them out, turning away before he lost his nerve. Those same cool fingers caught his wrist, the lips curling and pressing across his pulse point. Jack started to drop to his knees but managed to stop himself, pushing down those ridiculous urges. He didn't have time, the Daleks were coming. Hundreds, thousands...cold blooded killers were coming in swarms.

"Wait" the command was soft, but he obeyed as if it was steel.

Jack looked back, still trying to smile, "What's wrong, Doc? Do you have some secret Dalek-killing technique? Because I could use it."

"Don't I get a hug and a kiss good-bye?" the Doctor teased "You were so eager to give Rose a proper send-off, and all I get is-"

Jack threw himself into the man's arms, holding tight. He pressed his cheek to his shoulder, breathing in the aliens scent of the TARDIS and warm leather. Strong arms circled around his own torso, the hug returned full force. It felt wonderful and safe, each point of contact like fire on his skin. Couldn't he just stay here? Live as the Doctor's companion, help with the ship, travel the universe...stay by his side and in his bed.

It was just hopeful thinking, a pipedream. The TARDIS was never meant to be his home, his eyes were never meant to see the Doctor's sheets...he just had to accept it.

"I'm scared, Doc" Jack confessed, his voice barely a rasp in the man's ear "They're coming. We won't stop them and they'll kill everyone and it'll be our fault."

"Stop that" the Doctor squeezed him harder "I'm never on the losing side. You hear me? Never. Today's no different."

"Maybe, but..." the human buried his nose in the other's neck, taking a moment to indulge his primal instincts to scent "They're going to kill me, aren't they? You guys will win, but this is it for me."

The Doctor's silence was all the answer he needed, he swallowed a whimper.

"Damn it all, I wish I had never met you" Jack's lie was followed by a rueful chuckle "I was a better coward."

"You're a fantastic hero" the Doctor pulled away, holding the human by his shoulders to really look him over "And a good man. I know, I've watched you become one."

Jack started pulling himself back together, "I'm taking as many as I can with me."

"Good lad" the taller man gave him a firm shake, making them both grin.

"I think you mentioned a kiss?" Jack gave him his most charming smile, cupping the man's face and getting close. He couldn't die without a taste, he'd spent too many nights fantasizing about the most intimate of acts with this man to let this one innocent gesture go. The Doctor didn't seem surprised, a small smile on his face as the human took a kiss from him.

That one touch caused them both to moan, heavy pheromones rolling off them to fill the room in seconds. The kiss was electric, setting off bells and whistles and fireworks and lights and everything in their bodies and minds at once. Jack fell into the Time Lord, the man's stalwart grip the only thing keeping him upright. He couldn't believe this was happening, only an alpha could set him off like this!

The Doctor pulled away with a growl, a deep red film had fallen over his eyes and his canines had sharpened. He looked positively demonic. Jack's body was reacting violently, he couldn't hide how full his cock was or how embarrassingly wet he was getting. His head filled with images of him pinned down to a bed, thighs forced apart and a thick cock piercing his wet hole. His cheeks and ears colored at the thought, but oh how delicious the images were. Though human alphas didn't have those fangs, he was sure he could adapt to some prominent neck-biting. To be blooded...bonded forever with this clever man, it made his blood boil in his veins.

Jack went to pull away but the Doctor growled again, yanking him back.

"I-I didn't know you were..." Jack trailed off, staring in awe at the other.

"I knew" the Doctor's voice was low and in control "I knew you were in heat. How could you think I didn't smell you? Your need haunted me for days after. But I didn't know you wanted me so desperately."

"How could I not?" Jack was trying to keep some bravado even as his knees started to go "No alpha has ever made me like this."

The Doctor pulled him back into the circle of his arms, capturing the humans mouth. Jack moaned at the contact, parting his lips and letting the other taste him. It was true, he'd never let another alpha take him. Sure, he'd been fucked, but only by particularly attractive betas or species he knew couldn't get him pregnant. The chances of contraception were low but he didn't want to test the odds, it wasn't worth it. That, and he'd always been (kind of) waiting for the perfect alpha to mount him.

Well, he'd found him.

"We've wasted so much time" the Doctor's tone was bitter when he pulled away from the omega's sweet mouth "The thing I play with like a toy...and we've run out. I'm sorry, I'm so sorry...we could've..."

Jack's heart swelled in his chest, overwhelmed. The fact that the Doctor actually wanted him was enough.

"Alpha" Jack purred, nosing into the man's neck. Hot breath poured over his own neck, fangtips barely scratching the surface. Oh, if they were anywhere else...

"I would've let you have me completely" the human bared his neck, one of the ultimate signs of submission "I would have been so good for you. I wouldn't have said 'no', not once. I would've spread my legs and moaned so sweetly for you, Doctor. I would've done anything for you."

The Doctor was practically panting, his hard length digging into the human's leg. Jack tried hard not to rut against it, his body screaming to have it inside him. He could feel the thickness through the material, he could vividly imagine how it would feel splitting him open

"You will" the Doctor promised "I'll keep you strapped to my bed, open and ready...I'll take you in every corner of the universe."

Jack teared up, "That sounds fun."

"It will be" the Doctor insisted.

"It would've been" Jack brushed their lips, arousal fading into a low smolder of love and dedication "But I need to buy you some time. I need to get out there."

The older man's grip tightened further, pain racing up the human's arm, "Let them do it. I need you back in the TARDIS. I need you safe."

Jack sighed, breath stuttering, "I found the perfect alpha too late."

"It's not too late!" the Doctor's fangs rescinded, the crimson fading from his eyes "You think I'm something special? You're the one worth fighting for."

"It's much too late" the captain pried the fingers from his arms, dropping kisses on the knuckles "I'm going to die here...but I'm going to die with my head full of the most brilliant, infuriating man I've ever known."

"I won't let you die" the Doctor was determined "The moment you see the Daleks shut off I want you back here and into the ship. I'll wait for you."

There was no arguing with him, he had that look and that set to his brow.

"Okay" Jack conceded "I'll run back here."

The Doctor's smile was faint, his hand coming up to cup the captain's neck, "I didn't think there was a compatible submissive for me in all the universe. I looked for a hundred years, but not one of any race made me feel. I've just found you, and..."

"You found me" Jack leaned into the touch "That's enough."

The Doctor grimaced, "You know me. I can never get enough."

Jack could feel his body straining toward the other, "I need to go now. We're wasting time."

"Go" the Time Lord let him go, taking a few steps back "My teeth are itching to bite you. If I do that...I'll never let you go."

Jack shivered, nodding in agreement.

"You better stay alive, omega" the Doctor smirked, using the human term for the first time in years "That's an order."

"Yes, Alpha" Jack purred, getting a low growl in return "No good-bye?"

"Never good-bye" the Doctor swore, shooting him a wink "Just a 'later'."

Jack's smile was genuine, hopeful even, "Later, then."

The moment they lost sight of each other, their hearts broke.

xXxXx

"Last man standing here! For God's sake, Doctor, finish that thing off!"

Jack put up one hell of a fight, but in the end he was cornered like a rat. He only had so many bullets. But God damn it, he took a lot of them down. He stood with his back to the wall, three of those garbage cans were lining up in front of him. A firing squad. Perfect. He kept his chin high and his fists at his sides, refusing to cower before them.

But his mind was gone, lost in fantasy.

It was true, they had wasted too much time dancing around each other. To think he'd spent three days with a fake cock up his ass when he could've had the real thing in his bed. All those elaborate fantasies, all those sleepless nights and steamy dreams...all those repressed desires, all those guilt trips, all for nothing. He'd been so hard on himself about his affection for the Doctor and all he'd had to do was bare his neck to him. The whole thing was kind of hilarious, at least it would've been if it wasn't for his impending death.

"Never doubted him, never will!"

His own words echoed in his mind, he remembered that last blinding grin on the Doctor's face. Perfect. That's how he wanted the Time Lord to remember him. A leader, strong and sure, a symbol of strength. Fuck, he should've been born an alpha. He was just so amazing...

"Exterminate!" the machine grinded, their little death lasers extended from their body.

False bravado wouldn't save him here.

Jack blocked out the grating drone, letting his eyes fall shut. He filled every nook and cranny of his mind up with the Doctor. His stupid grin, his brilliant blue eyes, the smell of his jacket...that laugh...the touch of his hand...

"You're the one worth fighting for."

He wasn't lying earlier, the Doctor would've been the perfect alpha.

Jack's full lips curved in a smile, "...Doctor..."

A second of light, then all he knew was pain and darkness.

xXxXx

"I'm sorry, Jack" the Doctor whispered to the TARDIS, Rose passed out on the floor a few feet away "I'm so sorry...I can't..."

He could feel his body dying, readying itself for the change. He had to be in the TARDIS when it happened, he would be vulnerable and very unwell for the next few days. He couldn't wait a moment longer. He could see the golden tendrils creeping under his skin, threatening to eat him alive. Every dominant instinct he had was screaming at him to go back and get his submissive, but he couldn't.

Jack was strong and resourceful, an "omega" who lived the life a what the humans call a "beta". He was one of a kind, his Jack. He was so sure they would've been perfect together, no matter how brief their time together. He could picture how good Jack would look bent over this control panel, stark naked and mewling his name...begging for anything the Time Lord would give him.

He would bet his psychic paper that Jack begged more sweetly than even the most talented whore.

The Doctor shook his head, knocking the fantasy away. He couldn't go down that road, his hands were already twitching towards the buttons that would taken them back to that forsaken satellite. He hung his head, guilt swamping his hearts.

How could he just leave him behind? Jack was the first person to make his hearts pound in hundreds of years. The human had triggered every dominant instinct he had, his hormones had gone crazy from just the scent of Jack's arousal. He'd even broken face for him. He was a bastard, a lowlife, scum...he didn't deserve Jack. The captain needed to find someone else, someone worthy of his love and dedication.

That is...if Jack was still alive.

No, no...through the pain of dying, he could still feel the human's presence. It was like a warmth in the back of his mind, soft like butter and just as smooth. His boy was alive, he could feel it.

The Doctor almost flipped the switch, he almost went back, but he couldn't.

"Don't let me forget him" the Time Lord whispered to his ship, stroking the console lovingly "Please, lovey, don't let me forget him. I have to find him...I have to get him back. Can you feel how much he means to me?"

The TARDIS purred in response, vibrating briefly beneath his palms.

"You know it" he groaned, a burning pain blooming in his stomach "That stupid, stubborn, reckless git...he could be my everything, if I let him. And you know what, old girl?"

The Doctor closed his eyes, a weak smile on his lips, "I think I'll let him."

xXxXx

Everything hurt, but at least the darkness was gone.

Jack stood on shaking legs, practically falling into the wall. He pushed himself off, going for the hall where the Daleks had been. He dropped down to one knee, running his fingers through the fine ash piled on the floor. What had happened? He'd been expecting dead droids...or droids ready to kill him again. It wasn't dust, these things had been fried.

The sound of grinding metal rang through the air. He knew that sound all too well.

"No" Jack felt his heart crack, his omega instincts flaring back to life "Wait for me!"

Jack raced down the hall, knocking into the wall twice in his haste. He rounded the corner rather sharply, catching himself on the doorway. He watched the TARDIS fade away, flashing in and out of existence. He ran at it, new heart pumping hard in terror. He went to grab the handle only to handle air, the ship gone.

That was it, that was all his heart could take. He could feel it breaking, shattering, pain spilling into his lungs and through his stomach. He groaned, curling his arms around his stomach as he hunched over. It hurt, it hurt so much. It felt like he'd eaten needles and pure fire, everything inside him tearing itself apart. He dropped to his knees, tears leaking from the corners of his eyes without his permission.

His alpha had left him behind. The Doctor had promised to stay and he'd lied. Jack trusted that man more than he'd ever trusted anyone, and now that trust was broken. His alpha had sworn to wait, had said he wouldn't leave him behind...and it was all a lie. The Doctor had spun him sugar sweet lies of bonding and heat, but it was all fake.

He'd taken Rose and left in the TARDIS, abandoning him.

That's what was tearing him up. His new alpha had purposely left him behind and taken a beta with him instead, and he'd been just down the hall. No message, no more promises, no way to get back...just the after-image of the TARDIS and crippling pain. The sadness was deepening, dragging his shattered heart down with it.

Jack laid down on his side, laying his head down on his arm while his free hand massaged his chest and stomach. The ache was too deep to just massage away but he sure as hell tried. This was why the omega race was dying out, this right here. This nasty sickness growing in him would only get worse before he went numb. An omega torn from their alpha became a shell, a hollowed out body, worthless beyond belief.

The Doctor was gone, taking his warm feelings with him.

What was he going to do now?

Hope you enjoyed my little fic here. My first attempt at both the Doctor Who fandom and the omegaverse. If you review, be kind, for I am fragile.

Next chapter: 10 gets a message on the TARDIS, his alpha instincts flare and he goes back for his precious omega Jack. Where has he landed up? Will be raunchy

BTW: The inspiration for this story is "Flesh" by Simon Curtis. I highly recommend listening to it, it's hot :)
