THE IN HEAT/IN RUT AU MEME
not an alpha/beta/omega meme

There's no need for elaborate backstories for this AU. You go into heat, rut, whatever you'd like to call it. You've always done so since you were of age to do so. It's a socially accepted norm, and people have gotten used to the difficulties that come with the mating seasons. Life goes on.

Isn't this alpha/beta/omega, then? No, not at all. In this meme, there are no gender-variant genitalia unless your character comes prepackaged with those. No giant cocks - again, unless your character is already packing - or self-lubricating assholes or anal wombs, and no knotting. Unless that's your thing. There's also no set in stone roles with regards to dominance and submission, and some people do not even feel the inclination towards either. Still, there are a few similarities, mainly being that the pheromones of others can put someone into heat that was not in it before and the bond between mates. In addition, some humans/human-stand-ins have created packlike dynamics in response, but this is not universal.

In this meme, it's just regular old human...oids feeling the urge for sex. And by "urge," we of course mean all-consuming drive. If characters choose to ignore that urge, it will backfire on them. The more they put it off, the more they will lose their control, becoming more irritable and aggressive, and eventually be nothing but a rutting animal until the need to mate is satisfied. Not all heats call for mating, of course, and most people can just relieve themselves, but when you do mate, you feel the urge to stay by their side and essentially "nest." These desires don't always pan out into offspring, and mating isn't forever unless it's mutually decided upon. However, impregnating your mate is said to be one of the most euphoric experiences a person can have, even if some people only mate because they want to utterly possess someone, as mates are bonded for a while.

If there's anything that's to your fancy that's been left out, go ahead and add it in. Play it how you'd like!

PROMPTS

first heat: Baby's first heat. YOU'RE A TEENAGER/LATE BLOOMER AND WHAT IS THIS?

old hand: You've done this a million times, but it never gets any easier.

happen to be here: You're not picky. You can't afford to be. You'll take anybody who's nearby.

old faithful: You're going to the person you always go to in order to relieve your problem.

worked something out: The two of you aren't involved. You just help each other out.

unexpected: You never expected to rut with this person, but here you are.

forbidden: AKA the obligatory incest or age difference option.

volunteer: You've offered yourself up out of the kindness of your heart.

tribute: This isn't your offer. You're the offer from others, a gift for someone powerful to sate their appetite.

mating: You've decided to go one step further and make your relationship deeper.

nesting: Aaah, (temporary) domestic bliss. And lots of fucking. Lots and lots of fucking. Like, you'll barely be able to stand.

bonding: The bond, which is mildly psychic and intensely physical, makes sex even more intense.

the natural conclusion: Heat calls for pregnancy. Get someone pregnant.

already pregnant: Unfortunately, being knocked up doesn't abate your partner's desires. Or yours.

mates for life: Now you're absolutely certain that you want to be with no one else. Of course, this means you'll be in synch with their heat for the rest of forever.

save you: You've been saved from the advances of an undesired mate by someone who may be much more suited. Show your gratitude?

cockfight: Two people want the same mate. That won't do. There are ways to figure that out, not always involving fists.

increase in dominance: Exactly what it says.

increase in submission: Again, exactly what it says.

unexpected dominance: No one expects you to ever be dominant. Prove them wrong.

protect: You want to protect your mate from others, and that means putting your scent all over them.

set off by someone else: You were doing fine until you got a whiff of someone else's pheromones.

resisting temptation: Your heart belongs to someone. You want to stay out of this "heat" thing. You want to rise above it. Whatever it may be, you just have to not take the bait. Easier said than done.

all worked up: You're beginning to lose control and yourself. Quick, do something before you're jumping anything that moves.

pack: As mentioned prior, some people, especially those far out from civilization proper, have formed packs that hold to the more traditional alpha structure. Of course, these packs come with their own rules when it comes to heat and mating.

suitable partner: The desire for certain mates can come from a subconscious level, and you can find yourself aroused by someone showing how strong they are (they can protect you), how curvaceous they look (that must mean they're fertile), or any other number of traits that can benefit you.

desperation: You'll take anyone! Anything!

final release: You've reached your breaking point and your mindless. At least you'll get relief.

fighter: Part of your process is seeing who's worthy of you by testing their mettle. That, or you want to fight anything.

off your meds: It's fairly rare, but some can get blockers for their heat. What if those blockers run out? Why, it makes your heat ten times worse!

noncon: They don't want this. You don't want to stop this.

dubcon: You say no, but your body says yes and you can't stop loving it.

calm you down: Whether it's to fuck or to fight, you're going mad, and they have to bring you back down to Earth.

territorial: How dare someone look at what belongs to you? You'll have to make things right.

odd man out: For some reason, you don't go into heat. Never have. Being with you is pretty relaxing, and some find it appealing to not have to deal with pheromones that aren't theirs. You do have to learn how to appreciate their problems, though.

WILDCARD

Flat | Top-Level Comments Only

“I…I mean both?!” He snorted and laughed at that, the same cute squeaky laugh that drew MJ to him at first.

Then she posed like that, his eyes boggled.

SNAP.

His underpants gave up and shot across the room vanishing somewhere near the bed revealing a cock that was far too big to be human. A thick shaft, flared head. Unmistakably horselike as her shuffled forward and grabbed her hips roughly.

“I’m here.”

He guided the shaft between her legs and let it grind against her wetness, thrusting a few times experimentally feeling her lips on his length without going inside yet.

She caught the faintest glimpse of that cock before he closed the distance and MJ gasped sharply as she felt him grinding against her. That definitely wasn't his actual cock, but she really shouldn't have expected that he'd turn away from the chance to fuck her with something a little more exotic. Since their last time, it was like a dam had burst and he knew she'd be into it regardless of what was getting into her.

That was definitely doubly so now, given the almost pained groan she made as she pushed back against him, desperate to be penetrated. She didn't quite know what she was in for since she hadn't gotten a good look at what he was working with, but she knew that he was so close and yet not actually riding her yet.

"Please," she heard herself murmur insistently, rocking her ass back against him as her pussy all but dripped with her need. "Gar, don't be a tease."

“W-who’s teasing?” He groaned and shivered. His cock gave a throb and she would feel a trickle of precum running down her thighs. Drawing his hips back again he kept a hand on her hip to hold her steady and used his other to guide the tip to her slit.

It was Thick with a capital T. Maybe five or six inches around? But just as whatever logic was left in her brain might warn her it would be impossible…

“POP”

The flared head was inside her with an audibly juicy sound and a moan from Gar as he threw his weight into her and started rutting his hips to drive it deeper.

For a moment, she didn't fully realize what that was pressing against her entrance like that. It felt closer to a softball or handball or some other kind of ball that definitely wasn't meant for this kind of sport.

But that heat coming off of it was unmistakable, and as much as the human part of her brain wanted to push him away and insist on a little bit of foreplay to stretch her out before just diving in with that thing, it wasn't her humanity that was winning this round.

Besides, that widened tip was already inside her, and there was no way it was coming out until he was good and ready. And given the way he simply threw himself into her the rest of the way, he wouldn't be ready for that anytime soon. And neither would she.

Even though she grunted at the feel of that flared head being pushed impossibly deep into her, MJ's body welcomed him in with surprisingly little resistance. Spreading her legs a little more to give him more room to work, she fumbled for only a moment before driving back to meet his thrusts.

"Y- yeah," she panted out, some of that burning urge to mate finally quelling somewhat. "J- just like that. Push it all the way in and ride me hard."

“F-Fuck you feel so good! You’re so hot!” He grunted and his voice was already sounding more distorted.

His cock throbbed inside her in between each thrust of his hips. Inch after inch pushing deeper and deeper into her. Six inches, seven, the heat pouring off his cock flooding her body.

His chest against her back let her feel the changes as his body began to grow wider, heavier. Almost squeezing the wind out of her lungs and smooshing her into the bed before he took his melting hardening hands off her hips and planted them into the mattress, no longer hands but hooves.

Barely able to fit in her room, a massive green stallion was jerking and twitching its hips to plunge deeper, eight inches, nine…TEN!

Every thrust seemed to push him in even deeper than before, and MJ realized too late that he was definitely growing. Not just his cock, but all of him. He was getting heavier by the second, and MJ couldn't hold herself up on her hands anymore, stumbling face-first into the mattress even as she blindly reached for his arms for purchase.

Oh. Except those weren't arms anymore. Peering over to her side, she saw the unmistakable shape of a hoof and suddenly remembered Gar mentioning something about horse cock the last time they'd been together.

"Oh fuck!" Her voice was quieter than one might think, almost a squeak as she realized that she was in something of a dangerous situation. Hell, people have actually died from this.

But even as he continued to fill her up as he drove into her, this didn't feel dangerous. If she really let herself think about it (or rather, not think about it too hard), this felt right. Perfect even. He'd cum so much and be able to coat her insides with it and she'd get pregnant for sure....

She grunted a little as she struggled to keep her ass in the air, trying to ignore the blatant urge to get knocked up. They were fucking, just fucking, and she was going to enjoy it up until it hurt.

"S- so big-..." she gasped out, wondering if that cock would actually grow the length of her entire torso. How her insides were coping with this, she had no idea, but she was of no mind to stop or slow down. "Ngh, yes, impale me on that thing, Gar. D- don't stop til I'm soaked in your cum!"

He answered her command with a whinny that probably startled whatever neighbors she might have, then again after the animal filled day the city was having they probably would just put headphones on and hope that the problem solved itself.

Doubling his efforts seemed to mean faster and harder, each thrust coming in half the time as before, the last thick hot inch of cock forced in till she could feel his balls slapping against her with each thrust. The bed creaked and groaned under the stress but somehow her body was taking the entire thing perfectly. He was almost sure if she were to flip over he'd see the bulge in her belly, but he wasn't at any sort of angle to test that theory given his new horse head.

Instead he snorted and bucked into her throbbing and feeling his hard cock get tighter, so close to cumming already from the absolute heat that had been roiling them both for hours. But he couldn't hold it back much longer.

And it sounded like she didn't want him to.

That whinny from Gar sounded perfectly natural to MJ, and if her neighbors thought differently, she couldn't care less. She was getting what she wanted, what she needed, and if she ended up screaming loud enough to shatter eardrums when she finally orgasmed, so be it.

When she felt those heavy balls slap the back of her thighs, she groaned thickly, wrapping an arm around her stomach. She could actually feel him as he moved, her stomach rippling with each thrust, that flared tip bulging along her slim body as it beat mercilessly against her cervix. It should hurt, it should be agonizing, she should have shattered her pelvis just accommodating that tip, never mind the rest of him. Instead, MJ just wound the fingers of her free hand into the sheets, giving her purchase to at least attempt to fuck him from her position on the bottom, all but growling in her efforts.

"Come on," she insisted breathlessly. "C- cum, Gar, please. I'll do whatever - hah! - w- whatever you want, just f- fill me up, please!"

The sound of balls slapping against thigh, of a much too large green cock being forced into such a tight wet hole were filling the room with even lewder sounds then last time as Gar groaned and neighed again, melting into only two audible...very human words.

"I know!"

And then MJ would feel it. A twitch that started in his hips against her ass and carried all the way into a shudder passing through his cock and therefore her entire body. Throbbing became harder and hotter and he howled with pleasure as cum began gushing out of him and into her with enough force she would feel the first spray flooding her.

Digging his hooves into the mattress and twitching his hips he kept her pinned pressing more weight into her so she couldn't move, as if she'd want to at this point. Finally getting the sensation she'd been craving for hours now but in one of the most extreme ways.

And he was so distracted by the relief flooding into his brain he didn't even notice he'd somehow spoken while still in horse form. Pure lust had unlocked a new power.

Her grunts mixed into the wet sounds of him relentlessly pumping into her, and MJ was pretty sure she was going crazy, body hot and stretched around a giant horse cock like some living fleshlight. But when he started twitching, and each throb vibrated throughout her entire body, her own orgasm barely had time to roll over her before Gar came like a garden hose.

She was suddenly pinned down to the mattress as he gave in, the arm wrapped around her middle now sandwiched between their bodies and the bed. Maybe that was why she immediately noticed the way her stomach distended from the sheer amount and force of his cum, almost giving her the illusion that she was already pregnant and heavy with child, and rational thought left her entirely as her intense orgasm hit her hard, leaving her writhing under him as a primal scream ripped from her throat.

It felt incredible, but her hips still ground back against him as she rode out the convulsing climax, as though knowing she could survive that only left her wanting more. Even as Gar became more articulate in his animal form, though, MJ became less so even while looking wholly human. At least, as human as she could with a stallion buried balls deep into her and her belly stretched with the biggest load she'd ever taken in her life.

The weight over her began to lighten, muscle spreading out.

Rough horse fur became short and smooth, hooves melting into massive paws and claws.

Hot heavy breath on her neck as the massive horse cock began to draw back and change in shape. Thicker, wider till MJ would feel herself stretched in a different direction. The new shape thrusting to her still longer then any human had a right to be.

But so thick that it felt like not a drop of Gar’s cum was going to be leaking out of her.

The largest dog Gar could think of wasn’t an earth dog, but something he’d seen while visiting Kory’s homeworld. If MJ could see it she’d see that she was being fucked into the bed by something that resembled a Mastiff, but it was the size of a hippo with long green antenna and a mouth big enough to swallow her whole.

But mostly what she could feel was a hot heavy cock stretching her in different ways each time he bucked, another shudder being her only warning before a fresh gush of cum was delivered directly to her womb.

“M-mine…so hot…so tight…my mate!” He growled as he adjusted his weight so she could catch her breath…maybe.

She was nowhere near recovered from what she'd just gone through before she noticed the cock inside her changing shape, and MJ made a small whimpering noise as she instinctively thought he was withdrawing from her. She was stretched enough that there was no way she'd be able to keep most of that cum inside her once he pulled out, and the thought of losing any of it so soon-....

Oh. But he wasn't pulling out. If anything, MJ felt herself stretched even more widely, and she scrambled against the sheets a bit so she could turn her head enough to look at him and get a better idea of what to expect as he continued driving into her.

Except that she had no idea what that was. Her eyes widened as she could make out some vaguely canine features, but before she could even formulate the thought processes needed for words beyond the breathless keening noises she was making, she was being filled again, stretched beyond just what that cock was doing to her. The skin of her abdomen felt tight as it swelled just that much more, and she realized that he was cumming directly into her uterus, and even though she found herself wondering how much more she could take of this impossible fuck fest she didn't want him to stop.

When he shifted his weight, her hand moved to grab at one of his forelegs, as though afraid he'd move away. "Kn- knock me up," she heard herself gasping when she finally did find the words. "D- don't stop until I'm totally full. And then keep going."

"Anything for you." He groaned and drew back his hips a few inches. With the knot inside her that few inches felt like it might turn her inside out! But then when he thrusted back in she could feel a sensation like a wave of pressure hitting her from where the hips connected, traveling all the way along his shaft making the knot throb and the cock stretch her out once more.

Each thrust hit her like that sending the pressure and heat through his cock in waves till they were bouncing off one another in a feral sort of almost rhythm.

A heavy wet tongue ran along her spine flicking the back of her neck before she felt his teeth grazing her shoulder and a lusty growl in her ear.

"You're so perfect! So smart and funny and hot and tight! I'm gonna breed you every night, whenever you want it, however you want it till you're dripping cum from every hole!"

She nearly hissed as he pulled his hips back, that knot barely dragging along her insides before it started to tug. She couldn't help clenching around him, still afraid he would slip out of her and spill all that precious seed all over the bed. But thankfully he was an excellent mate and still wasn't done with her, and he pushed that cock back inside her so hard that she let out a deeply guttural grunt and came right on the spot.

Fuck, she wasn't ever letting him leave her if he kept making her feel like this!

She tried to keep up with him and rock back against him as hard as he was giving it to her, even if she intellectually knew that was an impossible task. Her intellect was no match for her instincts, though, and she was determined to keep writhing under him so long as she was able to move. That tongue along her spine made her shiver and moan, and she turned her head in such a way to let her long hair cascade over one shoulder, leaving the other exposed.

"Mark me," she told him, voice husky with need. "M- make me yours, Gar. Do anything you want to me, so long as I get your cum everywhere, every night, always."

"Every night." He thrust into her again "Every day." Another rock of his hips and his balls slapped her thighs. "You'll always have some of my cum left in your womb after tonight." He growled and lost himself in the heat leaning forward and sinking his teeth into her.

They were shape, the grip was so hard, the kind designed to crush bones but he stopped short of that. She would for sure have a scar there to remember tonight by. But he held her with his teeth in place and the thrusting picked up speed. Tail held high as he rutted in her harder, faster, so fast the bed was bouncing against the wall making even louder thumps as his claws tore into the mattress through the sheets.

She didn't know what she'd meant when she asked him to mark her. At least, she had no conscious idea that his teeth would sink into her skin, would never have asked for it if she were in a clearer state of mind. But the part of her that was an active participant in this situation knew dammed well what she was getting herself into.

And that part of her was loving every rough, destructive second of this.

That cock was fucking her faster, deeper, and every thrust forced out a thick grunt or moan as she still fought not to simply sink into the mattress. It felt like something of a losing battle, and she finally lowered her head in an instinctive show of submission. "F- f- fuck!" she hissed out. "Breed your bitch, yes!" She didn't care if he wrecked her bedroom or wrecked her pussy, so long as she got more of his cum pumped deep inside of her womb.

He growled around her shoulder and she could feel his hot drool dripping over it as he released her arm and lapped at the marks he'd left with pride. The heat radiating off his body was sweltering as he kept up this breakneck pace.

"Mine. Mine. MINE. MINE!"

His thrusts were already so fast but she felt the tightness inside her growing again. The throbbing of his cock as each thrust seemed to make it grow again. Was he shapeshifting once more or was he just getting close? His cock ached for release and he could practically feel her body melting to better shape around him as his knot pulsed and tightened her even more.

With a primal howl that rattled the windows he came again so hard his paws dug into the carpet behind them and his fur bristled. This cum felt thicker somehow, heavier then the goo already stretching out her belly. Could jizz be dense? Maybe but it felt like she was going to pop any second now.

Moaning deeply, MJ wanted to tell him that yes, she was his, and he was hers, and she wanted him to give her everything he had until she risked actually exploding. But words were beyond her now as she gave herself over to the pleasure, her inner walls clenching and twitching as she felt orgasm after orgasm rolling over her and threatening to drown her. She couldn't breathe, couldn't think, and she didn't want to. She just wanted to be rammed by Gar's cock until she felt too heavy to move with the added weight of all his cum.

When she realized he was getting bigger, all she could do was brace herself, fingers clenching at her ruined mattress as her mouth hung open and eyes widened in an expression of absolutely mindless bliss. She needed this, needed to be fucked and bred and made his, and when she finally felt more of his hot seed gushing into her and stretching her usually slim body beyond its limits, a harsh yell was ripped from her throat as she squeezed around him as hard as she could. That knot made it so nothing was going to escape her, but she absolutely did not want to risk it.

Her belly did indeed weigh her down, and lying against it now made an enjoyable pressure course through her as her body struggled to keep it all in. She could swear she tasted him in the back of her throat, and that was the only thing that made her stop panting like an animal, closing her mouth and swallowing on the off-chance a single drop of him tried to escape.

And finally...the world seemed to slow down again.

Heavy panting, warm breath on her neck as Gar's body began to melt and shrink against her once more. From thick muscular beast to firm solid man, his chest to her back and his lips on her neck.

But not all of him changed back, the knot aching in her pussy was evident of that as his hot sweaty body pressed her down into the bed all the same, his hips twitching and jerking as he shuddered inside her.

"Y-you saved me, you're so amazing."

As she struggled to catch her breath, MJ dimly noted that he was shifting into his more familiar form again. Well, familiar in terms of appearance; she's yet to actually sleep with Gar when he looked like Gar, and the fact that that suddenly bothered her a little must be a sign that she was slowly coming back to her senses.

Not that she was at all upset by what they'd done. Even as the various pains took the place of the frantic pleasure, she was still more satisfied than she could ever remember feeling in her life. Still being knotted might be helping with that, especially when her neck stung from the bite and she found it hard to so much as shift under him due to her added weight.

Though the muscles in her arms screamed at her, she brought a hand down to absently graze her fingers along her swollen belly, finally realizing just how full she was. "Holy shit, Gar," she gasped when she was finally able to speak. "Y- you-... that was-...."

Unable to properly define it, MJ could only chuckle breathlessly as she reached her hand back, intending to affectionately cup the back of his head. "You've officially ruined me for anybody else."
