Work Text:
Mike hadn’t seen Will in a few days.
He had known it was time for Will’s heat, and despite them being a newer couple, heats were…private. Intimate in a way that they had not yet achieved. But Mike hadn’t seen Will during his heats ever, because Will hadn’t ever had a normal heat cycle.
An unfortunate effect from the upside down is how Will explained it to him. Will’s heats were sporadic and could come on in a matter of hours after not having them for many months, or he could have them last for two weeks straight. Despite the infrequency causing them to be much more intense, Will always told him to stay away during his rare heats, at most letting Mike drop off some water and snacks a time or two.
But Will wasn’t dangerous.
Smart, and surprisingly sarcastic at Mike’s expense, sure, but never dangerous.
Mike was currently hesitating outside Will’s bedroom door, Will’s house remarkably quiet for once. Will’s mother was out on a badly timed work trip and Jonathan was at Nancy’s house for the night, which is why when Will had shakily asked for him through their walkie, Mike came running.
Slung over his shoulder was a bag with basic necessities. Saltines, water (the brand Will liked, of course), protein bars, and a few of Mike’s shirts.
Mike knocked gently.
“Will? It’s me.” He called out.
Silence.
“…Will?”
Maybe it was the worrywart alpha in him that caused him to reach forward and open the bedroom door instead of just leaving the bag outside like he had done before. If he had, things would’ve gone quite differently.
Upon walking into Will’s room, he shuddered from how cold the room felt before processing what he saw.
“Will!”
The omega was collapsed in a heap on the ground, tan sheets tangled messily around his bare legs.
He was also very naked.
“Holy shit, are you-“
Will’s eyes met his, and they were feral.
Mike froze like a deer in headlights, bag slowly sliding off his shoulder and hitting the ground with a dull plop.
One of the bottles of water rolled out across the floor, hitting the baseboard with a tink. Mike didn’t even hear it.
“Mike?” Will’s eyes were dilated so much that they could’ve made for hauntingly beautiful redraws of a black moon, but somehow the omega was still in enough of a headspace to recognize him.
Will tried to get up, struggling against the sheets, which were currently winning the battle against the omega. Mike was briefly hypnotized before realizing that he should be helping rather than gawking.
“Hey, easy, easy.” Mike rushed over to help him, crouching down on his knees while he gently untangled the sheets from his boyfriend’s legs. He very pointedly ignored Will’s erection with a blush, yanking the sheets off and tossing them to the side.
“Why are you here?” Will rasped out.
“You called me, Will.” Mike raised an eyebrow, thinking about how he could wrangle Will up onto the bed without the other trying to be more intimate with him.
They hadn’t had sex yet, but Mike wanted them both to be present for it.
“You need to leave. Now.” Will shuddered, before collapsing back to the floor as he curled himself into a ball.
“Woah, hey, I’m not gonna just…leave my boyfriend in a heap on the floor.” Mike scowled, “Let’s get you up on the bed.”
“Mike, You- You need to go, you don’t understand.” Will whined.
Mike reached out, cupping Will’s cheek. “Come on Will, let’s get you-“
He was splayed on his back before he could finish his sentence.
Will had shot up, eyes ablaze, before shoving Mike down onto the floor, quickly crawling on top of Mike before he froze, stopping himself from going any further.
“I told you to leave.” Will growled.
The Omega panted above him, sweat dripping down his neck. His canines were poking out, lips bloodied from the two jagged teeth catching on them. His scent surrounding them was chaotic, a bitter taste of longing and adoration wrapped in a confusing bundle of lust. His hormones were all over the place, and the room reeked of an omega who would murder anyone who got too close.
Will should’ve looked terrifying.
Should’ve felt dangerous, even.
But he wasn’t.
Mike’s eyes flicked down to Will’s lips, eyes going half lidded as he watched Will’s tongue poke out to lap at the fresh blood.
“Stop looking at me like that.” Will whined, “Mike, fuck, unless you want to have sex, you need to punch me off of you and leave right now.”
Mike should’ve felt offended that, despite being an alpha, Will thought that Mike wasn’t stronger than him. That Mike didn’t want this just as bad. Instead, he was quickly reconsidering his priorities.
It was probably fine to have sex for the first time during one of Will’s heats, right?
He was being a good boyfriend, a proper alpha, a provider even to help Will through his pain. Totally legit, and not him thinking with his dick at all.
Mhm, plan made.
Mike’s arms reached up and clasped onto Will’s hips, raising a leg to catch in-between Will’s thighs as he brought the other’s erection down to grind harshly on his thigh.
“Oh-“ Will shuddered, “Mike~”
His omega sounded so pretty when he said his name.
“Mike, that was a mistake.”
Huh?
The room suddenly felt several degrees colder, and Mike’s instinct told him to run. But his instinct must be wrong, this was Will, his beloved.
“You should’ve left when you had the chance.” Will’s eyes were dark, his hand smoothly trailing up Mike’s neck and cradling his face.
It distracted Mike enough that he didn’t think too deeply about one of Will’s hands reaching up into his hair.
Will’s hand suddenly clenched into his curls and yanked Mike’s head to the side, leaving his neck vulnerable. Before Mike could even process it, he felt Will’s teeth sinking into his neck.
Oh, fuck.
This was bad.
This was really bad.
But oh, it felt so, so good.
“Will-“ Mike choked, eyes squeezing shut as pleasure flooded his body.
Going by the rules of shitty porn Mike had watched, usually the gland biting happened during sex, and it was the alpha biting the omega to make them come first. But here his omega was, so desperate to have his alpha that he had to place his claim before Mike could.
Will bit down harder, hips stuttering as Mike’s hand slid around to feel down his ass, slick covering the area and dripping down Will’s thighs. One of Mike’s fingers slid a small dip into Will’s entrance with ease, and the omega whined around Mike’s neck, hand still clenched into Mike’s curls. The angle was just such in a way that he couldn’t fully push his fingers in.
Mike’s eyes peeled open, blurry room coming back into focus through the waves of pleasure. Will pulled away after a few more moments of Mike teasing his entrance, blood dripping down his chin and smeared around his lips. Will’s tongue lapped up the liquid around his lips, his eyes still dark with the hormones that only a heat could cause. His hold on Mike had weakened, the rush of sensation from biting Mike still overwhelming his system a bit.
Mike adored seeing his omega so needy for him, but now?
Now, Mike wanted to devour him.
Will’s eyes were still glazed over when Mike’s hands wrapped around his waist, pulling him back down gently in a softness that Mike only reserved for Will. He gently nuzzled into Will’s neck as he felt his canines start to sharpen in anticipation.
And then he calmly sank his teeth into Will’s neck gland, and he was home.
His omega melted into him, and Mike heard a soft whimper from above.
“Shit, Mike-“ Will moaned with feeling, and Mike shuddered as he felt the front of his pants dampen from an outside source.
Will had just come untouched.
His omega was sensitive, wasn’t he?
Will’s slick had soaked the front of his pants, a giant wet spot that would most likely stain. Will went boneless on top of him, not reacting at all when Mike released his neck and flipped them around, putting his omega flat on his stomach before pulling his ass up into the air.
“Present for me?” Mike calmly asked (demanded), pulling away to yank all of his clothes off, feeling weirdly overdressed.
He had only taken his eyes off of Will for all of thirty seconds while he did the world’s quickest strip (not an easy feat when you were crouched on the floor), turning back to Will.
The omega had somehow in that time regained clarity, regained his erection, and flipped back around with his body fully sat up. Will’s eyes were heavily focused on Mike, muscles tense like he was about to pounce.
He definitely would’ve if Mike had taken even a second longer.
Mike scowled, ignoring the way his cheeks flushed hotly at the thought.
But they could do that another time.
Instead, Mike pounced on him.
He grabbed Will, flipping the omega with an ease that clearly startled the other. Mike was lean and thin, but just because he had more spread out muscle didn’t mean he wasn’t strong. He pulled Will’s hips up with a firmness that left no room for any other bratty behavior, and he let his dick slide in immediately.
God, that felt good.
“Fuck.” Mike hissed, watching as Will went pliant again.
Will’s chest and face was mushed into the floor, hands grasping at the floorboards for purchase, scraping blindly. His hips were raised to meet Mike beautifully, and had Mike been an alpha in rut, he would’ve forgotten the move for dominance that Will had almost tried with him moments prior.
Unfortunately for Will, he was not an alpha in rut.
Instead of moving, he stayed still.
Will wiggled a bit, before turning his head, “You can move Mike.”
“No.”
Will froze underneath of him.
“N-No?” Will sounded befuddled.
“Not until you apologize.” Mike’s tone sounded bored, but his heartbeat rushed loudly in his ears.
“What the fuck, Mike?” Will started to sit up on his elbows, before Mike gave a single, sharp thrust then stilling again.
“Ah-“ Will’s chest slammed back into the floor, body spasming at the rolls of pleasure coursing through his body.
“You tried to take control.” Mike scowled, like he wouldn’t have gone along with it if it happened.
Honestly?
He just wanted to make Will squirm more than anything.
“Fuck, Mike, are you serious?” Will moaned, “I’m sorry I bruised your frail alpha ego.”
“Not good enough.” Mike hummed, and then he started to slowly pull out.
“Wait!” Will yelped, head snapping up as he looked genuinely worried that Mike would walk out over this.
Then, Mike sunk slowly back into him.
“Guess I’ll have to fuck the obedience into you.” Mike cooed.
He started slowly thrusting, making sure to hit deep inside each time. He kept changing his angle, until he found the spot that made Will spasm like he was being electrocuted.
“Mike~” Will whined oh so sweetly, and there was the sweetness he was wanting to hear.
He angled his thrusts towards that exact spot, shuddering as Will continued to let out cute little moans and mewls in response.
Mike kept his pace steady, watching Will fall apart under him.
It was a few minutes of relentless thrusts before Mike felt himself getting close.
“You, hnnn, want my seed inside?” Mike kindly asked.
“Yes, Yes-” Will whined.
Perfect.
“Then apologize.” Mike sweetly responded, slowing his pace down enough just enough to where it would be frustrating.
“Motherfucker.” Will growled, and Mike shuddered as he sharply thrust into him accidentally at the sound, “Mike, if you don’t come in me I’m going to get up off the floor, force you back down again, and ride you until you’re a sobbing mess. And you’ll be the little bitch apologizing to me, because you’ll be crying like I’m your mommy.”
And oh could Mike imagine it,
could imagine calling him m-
Mike was coming inside of Will at the thought, pride abandoned as he emptied out before his omega had come again.
He slid out after a moment, collapsing next to Will while panting on his back.
“Fuck, Will, give me a moment to get it up again.” Mike groaned, eyes fluttering shut.
A few moments passed, before Mike felt his legs being pulled open.
“No need.” Will cooed.
Two of Will’s fingers pressed into his asshole, Will’s fingers lubed up with his own omegan slick. Mike startled as he shouted at the intrusion, eyes flying open.
“Will! Mmm, shit, what are you-“ Mike moaned.
He looked down, and Will’s eyes were dark again.
Predatory.
Will’s thick cock swung as he rocked his fingers into Mike, and Mike’s eyes tracked the motion.
Mike felt hungry.
“Shhh.” Will murmured, “Let Mommy take care of you.”
And Mike squeezed around Will’s fingers, an embarrassingly desperate mewl escaping him.
“Fuck.” Mike moaned as Will’s eyes sparkled with the new information.
What the actual fuck was wrong with Mike? Really? When did that kink even develop?
“These went in a little too easy for a first time, baby.” Will cooed, “Did you finger yourself without me?”
“I-“ Mike was breathless as Will added a third, eyelashes fluttering as he struggled to keep his eyes open. “I was thinking of you early today when I did it, promise.”
Will’s eyes were a black hole Mike was lost in, both of them keeping eye contact the entire time.
Mike shivered.
“You think Mommy will fuck you when you fucked yourself without her permission?” Will’s voice was sickeningly sweet, and holy shit Mike was so into this.
“Will-“ Mike choked out.
“I think you need to apologize.” Will smirked, reversing their roles from earlier.
But fuck, Mike really wanted Will’s cock.
“I’m sorry,” Mike immediately folded, eyes watering with tears, “I swear, I won’t do it without your permission again. Please, please fuck me, I promise I’ll be good, Will-“
Will was frozen at the whimpering and pathetic alpha underneath him, dried blood around his neck as he begged for his omega’s cock.
This was what he had wanted.
He reached down in between his thighs, scooping his slick up and lathering his dick generously with it.
“I’ve got you, Mike.” Will’s voice deepened to his regular tone, and then he lined up and slowly started to slide in.
It wasn’t natural like when Mike slid into him, no. Will had to slowly go in, centimeter by centimeter. Mike may have already been loose, but Will was big.
“Will, Will,” Tears streamed down Mike’s face, the alpha clearly overwhelmed with the feeling of a cock inside of him for the first time.
“You okay?” Will paused, not wanting to cause any unnecessary pain, “Take a breath, Mike, and let me know when I can move.”
His words didn’t get through to Mike, the other hiccuping through his tears.
Finally, after a tense minute or two, Mike started to squirm.
“Did you…want me to beg more?” Mike shyly asked with a flush, wiggling his hips.
Well, that worked too.
Will hummed, letting his hips shallowly start to thrust back and forth.
“I want you to tell me exactly what you want me to do to you.” Will spoke softly.
“Fuck.” Mike panted, and Will let his shallow thrusts come to a halt despite his dick throbbing.
“I…” Mike swallowed, eyes going hazy with more tears, “I want you to fuck me, Will. Treat me like I’m your omega, bite me until I pass out, whatever you want, Will, I want to be good for you.”
“And?” Will tilted his head.
Mike floundered.
“What else are you supposed to ask when you make a request?”
“Please..?” Mike shuddered as Will started to shallowly thrust again.
“So close, baby.” Will smirked.
Mike’s eyes flickered with understanding, his face flushing bright red.
“I…”
“Come on, say it.”
“Please…Mommy…”
Will rewarded him with a deep thrust, chuckling as Mike sobbed in response.
So cute.
Will let himself start to pick up a rhythm, immediately finding Mike’s prostate and continuing to slam into it with precision. Mike grasped onto his biceps, unable to do anything but hang on desperately.
Just as Will wanted him.
“Will-“ Mike whined, and god, his alpha being so needy was really awakening something in Will.
“Yeah?” Will moaned as Mike clenched particularly tight into a thrust.
“I wanna come, wanna come, can I, please?” Mike was babbling again.
“Of course.” Will bumped their noses together, holding eye contact with Mike until the alpha’s eyes rolled back into his head as he orgasmed.
Will kept fucking deep into him, even as the alpha started to genuinely sob from overstimulation after a minute or two.
“Mommy-“ Mike was a wreck, sobs wracking his body, “S’ too much!”
But his scent gave him away. Mike smelled like embarrassment, lust, and a desire for more. So, with that being said, Will ignored his pleas.
“You’ll take what I give you.” Will growled.
“Will!”
Will leaned down onto the unblemished side of Mike’s neck, and right as he came inside, he bit down on Mike’s neck.
Mike screamed, body seizing up before going completely limp.
Will slowed his thrusts, before his brain caught up.
Oh shit.
The haze started to pull back from his brain.
What the absolute fuck was that?
“Mike…? Mike?!” Will started to panic, pulling out despite his dick already getting hard again.
Mike had passed out, and it was his fault. And yeah, Mike had asked for it, but they hadn’t ever discussed this sort of thing in detail. What was he thinking?
This
was
unlike
him.
Before he could dwell on it, the fog shrouded his mind quicker than before, like it had been waiting for him to realize.
Why did it feel…familiar?
What are you waiting for, Will? He’s all yours now.
Right…
Will knew what was best for Mike.
He slid back into the other’s hole, Mike’s limp body pliant as he started to fuck him again. He freely moaned, feeling more slick gush down his thighs. His alpha felt so good, so loose.
He was gonna fuck Mike’s hole until he could get his alpha’s stomach protruding with cum. God, he couldn’t wait to see Mike cry. Will let his lips lean back into Mike’s neck, but rather than bite, he started sucking.
He was going to mark Mike up with so many bruises that it’ll look like someone strangled him. His perfect alpha.
A bruise was now above the bite mark, and Will leaned in to make another. Then another, and another.
His,
His,
Theirs.
He came inside, filling Mike up nice and good. Mike’s dick had started to harden again, and Will felt his insides clench with need. But he still needed to fill his alpha more before he could reward himself.
Will felt his dick harden again, and he started to rock in and out, hand coming around to grasp Mike’s hard cock. Mike was completely unconscious, but his face was flushed as he started to whine despite being unaware. Aw, it looked like he was overstimulated.
Good.
Will kept fucking him slow, sucking and nipping anywhere he could leave a mark. He left countless marks on Mike’s collarbones, then grabbed Mike’s limp arms and worked all the way down those. They wanted Mike to look like he was owned, subservient.
Huh?
But then, he hit Mike’s prostate, and the way Mike clenched around him had him coming deep inside. That, that was the exact way he needed to come.
Perfect. He was surely impregnated now.
Will frowned.
But Mike was an alpha?
He glanced down, seeing Mike’s hard cock leaking pre-cum, and the omega in him ached. His alpha knew exactly what he needed, even when unconscious.
Will pulled out, shuffling on top of Mike as he reached around, aligning Mike’s cock with his entrance before sliding in.
“Oh, that hits the spot.” Will moaned out loud, frowning when he realized that Mike wasn’t awake to meet his thrusts up.
“Wake up, baby.” Will ground down, lightly smacking the other’s cheeks.
Mike still didn’t wake up, so Will started to clench around him. And that did the trick. Mike’s body start to stir awake, unconsciously giving a half-assed thrust up.
Will softly moaned in response.
“…Mmmmh?” Mike slurred, slowly coming into consciousness.
“Mike.” Will whined, grinding down, “Come on, I need you to fill us up good again.”
“…Us?” Mike’s voice was still groggy, half conscious.
Will.
“Well, you put a pup in me, didn’t you?” Will batted his eyes, moaning as he felt Mike’s cock throb. “Of course you did, you wanted Mommy to be nice and full, right?”
“Yeah.” Mike’s voice was a bit more alert, but for some reason it sounded a bit guarded.
Distract him.
“Mike,” He cooed, watching Mike’s eyes dilate, “I don’t feel full yet, can you come in me some more?”
“Yeah, yeah. I’ve got you, Will.” Mike’s eyes went glassy again, and he started to slowly fuck up into Will.
Will let his eyes flutter close.
And inside Mike’s stomach, Will could feel a newly made creature, not even an inch big, squirm pleasantly.
“Mmm, Will, my stomach feels weird.” Mike mumbled.
“Mommy’s cock may have been too big for you…need me to kiss your sore tummy better?” Will grinned, watching Mike’s face flush bright red.
“God, you’re so going to use that against me forever, aren’t you?” Mike slowly thrust up into him.
“Hnn, of course,” Will rocked back down, “You’re my good little alpha, aren’t you?”
Mike nodded.
“Good boys let themself get fucked,” Will cooed.
Let themselves get impregnated.
“It felt so good,” Mike’s eyes went glassy as Will bounced on his dick, “Really felt like I was your omega, heh.”
“Yeah, you let us impregnate you real good, baby.”
Mike was too fucked out to catch the slip up.
“Shit, can I come inside?” Mike moaned.
“Only if you let me fuck you again.” Will murmured back.
“God, yes-“
Mike came inside, and mere moments later, he was being flipped by Will again.
“Gonna impregnate you some more, Mike.” Will giggled, eyes dark.
They wondered how many creatures they could implant before Mike noticed. There was at least 3 forming ones now, small and barely noticeable. Will was going to make his stomach full, going to make so many that they ate Mike from the inside out, until he begged Will to make the pain stop-
But right now?
He would play the part of a mate.

Well done, Will.
