Heat salvation

Commission for @hanaotaku95

Request: In anticipation for Alien Romulus, may I request an A/B/O scenario where Female Reader is the only omega on their research station that is examining the Xenomorph lifeforms. Well, they escape and start killing people, and the reader has managed to evade. Fortunately, she goes into heat and this saves her life as the Xenomorph is a virile Alpha.

When you got selected to be one of the researchers in a very special project, you counted yourself lucky. Only the most smart omegas were supposed to be able to enter such elite program, and you got in. You were happy, you were better than anyone. You couldn’t be thankful enough. And you got to work with the most interesting alien species out there, researching and testing and being completely interesting. You were over the moon.

All the testing and poking was a big annoying, they snapped and hissed at you, but you got used to it pretty quickly. You were the only omega in the ship and that was a bit weird, but you didn’t care, you were happy to be researching aliens. That was enough.

Until the specimens got out.

Until the xenomorphs escaped.

It was a normal day in the lab, and you were just getting some tests done when you heard screams out of the lab where they did the testing. But then you heard the screaming in the distance and the scientists around you got all nervous. They tried to hide you, a normal reaction of betas and alphas protecting the only omega, but they didn’t have enough time. One second they were fine, the next second there was a big scary alien in front of you, killing them all.

He was the same xenomorph you were in charge of, the one that you tested, the one that knew you… But he hated you. You were sure of it. You tried to be as careful as possible, but sometimes some little pain was inevitable. Some of the testing was brutal and you didn’t want to do it all, but it was that or getting out of the program, and the taste of new knowledge was too good to pass.

You thought he was going to kill you, but instead he stopped right in front of you. He smelled the air and stare at you. His weird elongated head twisted to the side in such a puppy like gesture you had to bite down on your lip to avoid giggling.

“Are you going to kill me?” You asked. You knew he talked, but he never talked to you. You weren’t sure he was going to talk to you now, but you had to try, you had nothing else to lose. He was going to kill you either way.

He kept staring, and you almost thought he wasn’t going to answer, but then he surprised you. “You don’t need to know that, do you omega? You only need to know that your body craves mine. I can smell it.”

“What?” You were more than confused by his words, not knowing what he meant.

And then he surprised you for the second time: “You are going into heat. And you smell like the best food in the universe.”

“I- I don’t…” You gaped at him, your brain short circuiting for a second. There was no way, you weren’t due for at least a month, but the fast rise of your chest, your body overheating… It couldn’t be, could it?

“Don’t you feel it, omega?” He asked, smelling the air again and licking over his sharp teeth. You shivered at the sight. You were about to say no when he stopped you. “Don’t lie to me.” His growl was enough to send spikes of arousal down your body, your pussy getting wet as he growled again, smelling the air.

“Yes,” you confessed.

He didn’t hesitate to ask: “You want to be claimed? You want to be fucked?” His long tail was swinging behind him as you shivered. You wanted that. You wanted what he was offering. Your body craved him.

You knew you should say no. You knew it would be a bad, bad, bad idea to say yes. To tell that amazing specimen of alien that you did want to be fucked by him. That you were in heat… And you knew he was an alpha. But you didn’t even know if he had a dick, or something similar to that… You didn’t know if your bodies were compatible, but he didn’t let you say anything. He smelled the air and was over you in less than two seconds.

When his body covered yours, you were more than ready to be squeezed, to be fucked, to be used as however he pleased. You could only feel the heat and the way your pussy was getting wetter and wetter every second it passed. Your brain got disconnected from logical thoughts the second you smelled his alpha pheromones. It was maddening, your clit asking for attention as your nipples got hard. You were no better than any other needy omega.

He said something in a language you didn’t understand, and then he added: “Say you need this. Say you need my alien dick.” He rubbed what seemed to be a phallic organ against your damp center. You whimpered, and he ripped your clothes away, leaving you panting and aroused under his hard body.

So you didn’t even think twice before saying: “I need it. I need you. I need your dick.” You barely recognized your own voice anymore, but your need was too great to ignore, you never felt like this. Your other heats have always been suppressed and cared for by other betas or omegas, but the presence of an alpha, and your induced heat… It was too much, your whole body felt electrified.

“Good omega, such a pretty slut for his alpha.” In other situation that could have made you mad, but you craved his words the same way you craved his body. His dick was still rubbing against your center, this time spreading your juices all over his dick, creating the most delicious friction.

“Yes, alpha.”

He didn’t need any other word. He entered you in a long slow thrust, not stopping, not letting you accommodate to his girth, but it was good enough to make your eyes roll back into your head, your brain empty apart from images and flashes of his hot body over yours. Your hands grabbed along his elongated head, trying to grind yourself into him, but not being able to. He controlled every single millimeter of your body, holding you down as he fucked into your dripping cunt.

“Faster, harder,” your voice was barely a whisper but it felt like a scream.

“Beg,” he ordered, his tail curving around your neck, not pressing, but making you tilt your head back, your brain fuzzy.

You always thought you were above begging, that you would never… But there you were, first time with an alpha and being split open by alien dick. Nothing could surprise you anymore, you weren’t above begging, not at all. “Please alpha, please. Please. Please,” you chanted.

He laughed over you, cruelly and harshly. You felt absurd, but the second his tempo increased, you were ready to beg again if it was necessary. It was so good. He was so good. Such a good alpha. A bright part of your brain thought you were over your head, that maybe your heat induced you to like him… But in that moment you didn’t care. You were an omega in heat, and he was an alpha ready to give you everything you craved.

And he delivered.

He fucked into your pliant body, hands and those tentacle-like appendages holding you down completely, at his mercy. You couldn’t even squirm under his body, just enjoying what he decided to take, what he decided to give. You were a recipient for his dick, just an alien fuck toy, owned by your alpha… And you loved it.

His orgasm came first, filling you with molten lava seed, your insides turning and convulsing to be filled so deeply and completely. And that threw you over the edge. You came hard and messily around his alpha cock as he grunted over you, your screams muffled by the tail still wrapped around your neck.

He filled you over and over, until you felt like you were about to burst, just to pull out and do it all over again. He fucked you for hours, until you didn’t know which way was up and which way was down, until you were so cum-drunk you would give everything for your alpha, until your poor omega cunt was oversensitive and tender.

And then he did it again.

After you don’t know how many hours, he stopped, wrapping his appendages and arms around you in the weirdest embrace you’ve ever felt, but the most comfortable, too. Still panting, your head resting against his hard chest, you asked: “Why didn’t you kill me?” It has been bugging you since he appeared.

He said nothing for a few seconds and then deadpanned: “Because your omega smell was too good to kill. I prefer to keep you.” You didn’t know what to say about it, you were literally spared because you were an omega...

Weirdly enough, you were okay with that.
