Mating the alien

Patreon Commission for @wimble_warcrime

Request: As for the commission, are you familiar with the 'Ice Planet Barbarians' series by Ruby Dixon? The thing I'm thinking of is similar to the series in regards to plot - like human ends up stranded on an ice planet with only giant aliens to keep her company. Except, the aliens aren't seven-foot-tall blue people but more of a cross between a werewolf and a werebear? Something smutty, with a big emphasis on the typical soulmate trope and breeding kink/knotting kink? I also really liked the fic you wrote about the werewolf and marking his human with his piss - if possible, could you add something like that to it, please?

A/N: This was very fun to write, turned out a bit more soft than expected, but I think it’s sweet, enjoy!

When your spaceship crashed into the unknown planet, you weren’t expecting aliens to be there. Well, you kind of were in your wildest monsterfucking fantasies, but in reality you thought it was highly unlikely. Joke was on you when an alien as tall as a tree got to your scared self.

You screamed when his head popped over your broken glass, he looked between a werewolf and a werebear. freaky in a way that made your insides tingle with unknown feelings. But the confusion didn’t matter when you saw him and instinctively punched him in the face, not processing he was trying to help you. (You thought he was trying to eat you, okay?).

After a lot of screaming (from both of you), he got some sort of device inside your ear and then you could finally understand him. You were more than glad for that tiny something that was now embedded in your ear, you didn’t want to ask what it was, it looked like a bug when he pressed it against you. But it was okay, you could deal with an ear bug if that meant you could communicate with the alien species living on the planet. (And maybe with the fine alien who rescued you.)

You weren’t that lucky, though. As soon as you reached the village, he left you with some older looking aliens and disappeared much to your dismay. You didn’t see him for multiple days after that, but they gave you a place to sleep and nice clothes. And when he showed up again with a big dead something hanging from his shoulder, you screamed again, making him jump and drop the dead weight into the snow in front of your hut.

You looked between him and the dead animal (?) and couldn’t stop yourself: “What is that?!”

“A gift,” he mumbled as he turned around and left you there, confused and with a dead animal.

You were even more confused when he showed a couple more times with other weird “gifts”. But when the elders told you about soulmates and all that they implied, you had a revelation. You were more than sure than the one who saved you that day was your soulmate. You knew humans didn’t have stuff like that, but in a way, you could feel it. Deep inside of you. There was something that called you to him like a moth to flame, and you were so tired of him running away from you…

So the next time he showed up, you gave him the hat you were wearing when the spaceship crashed, making him smile at you like the sun just appeared after a long winter. He looked even more handsome when he smiled, and you couldn’t stop yourself from reciprocating.

And that’s how it started.

Between gifts and hanging out with each other you started to develop something more… Something deeper. And he seemed so happy about it. So, so happy that it rapidly escalated to something a bit more physical. To be exact, something with your legs over his furry shoulders and his face buried between your legs until you were soaking his fur and he was devouring you like a starving alien. But nobody could blame you, you were his mate after all (and maybe a bit of a slut when it came to big furry aliens).

But it still didn’t feel correct, there was something missing. And after another talk with the elders, you understood.

And you planned.

That big alien wasn’t going to know what hit him (aka: a horny human with lots of kinks).

He was pounding into your pussy, legs over his shoulder as he pressed down on you, making you moan so loud you were sure the hut next to his could probably hear you. You didn’t care, you were being fucked within an inch of yourself and he was saying the filthiest things against your ear, making you shiver with pent up arousal.

“I’m going to fill you so completely you are going to feel me for days. I’m going to fill you to the brim until you are so full of me everybody can smell it on you.” He kept feeding your breeding kink to the point of making you dizzy with desire, his dick so big inside of you it felt like you were about to be split open. “I’m gonna- I’m gonna…”

“Knot me, mate.” You knew what it did to him to hear you saying that.

As soon as the words were out of your mouth, he was burying himself deep inside of you and you felt his knot stretching you to the point of insanity. It pressed right against your G-spot and you had to cover your mouth to stop some of the screams as you came apart around his forming knot.

You breathed in unison for a few moments, his dick still filling you completely as he kept breeding you. You shivered at the thought, but then remembered your plan. “I want all of your marks on me,” you told him right after his first orgasm.

“What?” His brain couldn’t fully process your words as he kept coming inside of you, another shot of his come hitting your cervix. He looks down at your joined bodies pointedly.

“I don’t mean this. Well, yes, I do, but also the marks,” you tried to explain without having to spell it out. You moved your hips, pulling a low moan out of him. He looked at you confused, like a puppy. He was so adorable you couldn’t be mad at him for being oblivious to everything. So you swallowed around the knot in your throat (haha double knotting), and choked out: “I want you to pee in me after you… finish.”

He stopped breathing for a second, staring at you intensely. But the next shoot of his cum inside of you had him closing his eyes and moaning. After, he asked: “Wha- what? Who told you about that?”

“The elders.”

He groaned and rocked his hips, making his knot rub against your G-spot and making you see stars. “I thought… Humans don’t do that,” he muttered, your brain turning fuzzy with a new wave of pleasure.

You tried to focus so you could explain, it took a little while, but you finally said: “Humans don’t need to mark their partners with piss, but that doesn’t mean some of them don’t do it for fun and pleasure.”

“They do?” You hummed in agreement. “Do you- Did you… with anyone?” The low growl in his tone sounded jealous, and you felt bad for liking that. You liked that he was possessive, you liked that he was about to mark you completely.

“N-no,” you lied. He looked at you with big eyes, catching your lie easily. “Okay, yes. I’ve done it before.”

He smirked down at you, his mischief showing in every inch of his face. “And you liked it?”

“Yes,” you confessed. Even though his knot was deep inside of you, it was the confession that made you blush harder. “So… are you… are we... doing this?” You slowly let out, your voice breaking as he rolled his hips.

“Do you really want to?” He asked after a particularly good shot of his come made him moan your name like a whore. Dang, you loved how vocal your alien got when he was high on passion.

“Yes,” your tone was vehement when you answered, a twitch of his dick hitting right over your oversensitive G-spot, making you see stars and a wave of pleasure so intense hit you, you almost came again.

He kissed your forehead with an exhale, whispering: “You are perfect, my mate.”

After all that talk, you focused back on your body and felt how you were almost overflowing with his seed. He filled you up so completely you could feel it moving inside every time he rolled his hips. You contracted your muscles to milk him and smiled big when he groaned in response, praising your pussy. His thumb found your clit and he started to work you up again, slight rolls of his hips that mixed with his dexterous fingers to drive you higher and higher, your orgasm almost at arms reach.

But it wasn’t until his knot deflated that you could feel him fully, his dick didn’t go down, and he started pushing in and out of you again, the mess of cum inside of you being pushed out as he pushed in. The sounds it was making were driving you into the next dimension. His fucking driving you right to the edge.

And then you felt it. You felt the warm heat of his piss inside of you, warming you from the inside out, such a sinful moment that you felt your body floating as the orgasm hit you. You threw back your head as he peed inside of you, your body convulsing in his arms, your voice breaking with pleasure as he completed the union between the two of you.

He pulled out just in time to finish peeing right over your messy pussy and lower stomach, the heat making you groan once again, whispering nonsense about how good it felt, how nice and warm… Your brain couldn’t process everything, you never came so hard and for so long, but the feel of him in and out of you, the warmth and the utter fullness inside your soul was so much more than you could express.

When he finished, he pulled you up to his body, the mixture of fluids leaving your over-used pussy and leaking down the sheets, making an obscene mess. You were so tired you couldn’t hold yourself up, your body not responding after pleasure that intense. You looked up at him just in time to see a single tear rolling down his cheek. You pulled him down and licked it off his face, making his dick twitch against your abdomen.

“Let’s clean up so you can mess me up again,” you teased. His responding growl made your insides turn and twitch with anticipation, more than ready to be filled and defiled once again.
