Work Text:
Grace has been on Erid for about a decade now, and already he almost feels more acquainted with their culture than he is Earth’s. He’s made a ton of crazy smart alien friends, mostly through Adrian and Rocky’s connections. He gets to spend a lot of time with doctors and scientists that have worked to help him grow accustom to Erid’s atmosphere and temperature, too. Suffice to say, Grace is learning more all the time, and loving it.
Erid has made many scientific advancements thanks to everything he’s brought from Earth, and along with their unique strengths and view of the universe, he thinks they’ve probably far surpassed Earth’s science and technological capabilities at this point. He’s being a bit selfish, but he doesn’t want any other humans to come to Erid. He’s worried they might introduce horrible human ideals like… the economy, or something. Also he might no longer be a unique spectacle to everyone he meets.
Rocky and Adrian have been working hard to rebuild their relationship since he and Rocky returned from their journey to Tau Ceti. It turns out 50 years is a long time, even for a long-lived species like them. Still, they’re sickeningly sweet together. He’s not surprised when Rocky approaches him and lets him know they are considering having children soon. What does surprise him is that Rocky requests his help with the process.
He did, at some point, learn more about Eridian reproduction systems beyond the brief overview Rocky gave him when they first met. Eridians used to bury their eggs to improve the success of healthy hatchlings. Lower in the ground in its cave systems, Erid’s temperature decreases to a cool 130-150 degrees Fahrenheit. However, with modern technology, Eridians can improve the life expectancy of their young even further by securing the eggs inside incubation machines that cool them down to 95-100 degrees Fahrenheit.
It was super interesting to learn about all of this, and of course he chimed in, “that’s basically my temperature, you know?” But the scientist he was talking to already knew this. They got excited that Grace made the connection anyway. Yes, you would be a perfect incubator for Eridian eggs. There wouldn’t be any instinctual fear about predators stealing the eggs, if they were safe inside you.
Huh?
They were definitely a weird one, Grace thought. Grace tried not to freak out too much, and totally buried that information in his brain until Rocky brought it up one day.
“Why would you want that? Your eggs, inside of me? That sounds like some kind of sci-fi horror movie!”
“It would be perfectly safe for you, Grace. After all, our scientific advancements have already allowed you to live in our atmosphere and withstand the burning temperature of my touch.”
“That’s not even what I was asking. Why the heck would you want to put your eggs in me?”
“It was Adrian’s idea, actually. Don’t you want to be the father of our children, question?”
Well, Grace has already learned through years of trial and error that he’s unable to refuse anything Adrian asks of him. And the idea of fathering (mothering?) Rocky and Adrian’s tiny pebble babies activates something in his brain he doesn’t completely understand.
…
Somehow, after this series of events, Grace finds himself in the middle of an Eridian orgy. He’s surrounded by excited aliens with long tentacle genitals who want nothing more than to put their eggs inside him. It’s after he’s been used a few times in both ends that he realizes he doesn’t know where Adrian or Rocky went, and none of the other Eridians understand his speech.
Grace’s mouth is leaking liquid mercury and spit, his jaw sore from use. He sobs as the Eridian in front of him pulls out, expelling eggs onto the Xenonite tile below him. He tries to call for his friends, he doesn’t know where they went, but he needs their help right now.
“Stop, please, ptuhh,” he spits out mercury cum between begging, voice hoarse. “Stop! Rocky, Adrian! I had enough, please!”
Another Eridian, who has been caressing his face, leans its carapace to the side to press its entrance to his wet mouth. Defeated, he presses his tongue weakly against its wanting body. The Eridian fucking into him from behind helps maneuver him upside down and adjusts its ovipositor to enter him from a new angle.
His legs, kicking frantically, are held down by a tall cerulean Eridian whose job seems primarily to watch over him and keep him calm. This caretaker Eridian hums at him sweetly.
“Grace can take more. Grace is strong, strong, strong!” the supportive Eridian sings. “The babies will grow strongest and healthiest with more fertilizing!”
He sobs again. He wants to make Rocky’s babies as strong as they can be. The Eridian at his mouth parts its entrance and its tentacle-like ovipositor snakes out. The ovipositor wraps flirtatiously around his neck. It strokes at his chin, slithers up to swipe at his lips. He whines, trying to sing the Eridian word for “please”.
“Will fertilize soon, do not worry, sweet incubator.” the Eridian inside of him trills. Its ovipositor pulses inside of him in warning. “Eggs inside?”
He cries. Yes, please.
“Eggs releasing, now,” its voice wavers in the wake of its orgasm. “Wow! Alien whore is so good…”
Grace feels the familiar stretch of the eggs as they exit the ovipositor and fill him in a satisfying, intense stretch. It feels amazing, he dreamed about this since learning about Eridian mating, but he is beyond exhausted at this point. Rocky, please come back and check on me, he begs internally.
The Eridian inside him finally pulls out with a wet squelch, panting, and drags its claw gently across his belly, pushing a little against the indentations of the eggs filling him. It sings, trying to calm him down like the other Eridian before, but he can’t stop the sobs of over-stimulation.
“Please!” He screams. The ovipositor wrapped around his neck snakes up to prod at his mouth, shushing him. He whines and licks at the leaking tip, not wanting to displease its owner. His mouth is soon stuffed with prehensile tentacle dick, spit again leaking from the sides of his lips.
He chokes on the ovipositor for a minute, lost in the sensation, before being interrupted by the feeling of a claw brushing up against his entrance. It’s likely the caretaker Eridian preparing him for yet another suitor to have their go at breeding him.
Then, he hears a familiar voice.
“How is Grace doing? I heard its moans from across the damn building!” Rocky! Thank god.
“It’s doing amazing. It’s taken over a dozen clutches already. Its mouth is just amazing, too. You’ve done well to find this creature, so perfect for breeding.” the caretaker responds. Grace finds himself flushing, pleased with the compliment. Though the other comment takes him out of it a bit and he has to stop himself from giggling around the ovipositor in his mouth. A dozen already? They’re playing the scene up too much, it’s not realistic…
“I want to try its hole, please.” No, no, no… Grace moans around the ovipositor, needing to speak but he can’t.
“Go ahead. They just finished with it. Look at how many eggs are still inside… it has room for even more, I think.” the calming Eridian rubs at his stomach, and he feels an egg slip out of him.
“Yes, it has so many holes for eggs to be stored. There is no one more perfect for bearing my children.” Grace’s heart races, feeling incredibly honored but also terrified. His best friend who gave him everything, has been wanting this from him, too? Sure enough, he feels Rocky’s claw push at his entrance, pressing all three digits inside easily.
“Grace, you whore. You’re so full of all these dirty bastards’ seed.” His friend chuckles, low, at his expense. “And I bet you’re loving every second of it.”
The humiliating, dreadful, terrible part, is that he was. He just needs a break. Some water, maybe. And to get some of these eggs out of him. That relief doesn’t seem to be coming anytime soon. He feels the ovipositor in his throat slowly pull out, spilling its spend onto his tongue, smearing it across his face. He coughs hard, trying to catch his breath.
“Color?” Rocky prompts him.
“Green.” he responds immediately. “Rocky, please, I just need—”
“Shhh. Shut it up, please.” Rocky interrupts him.
The Eridian who just came in his mouth sticks a hand inside, pressing down hard on his tongue. He gags, eyes filling with tears.
“That’s right, whore. You were made for taking Eridian eggs.” Rocky uses two claws to spread his cheeks, pressing his ovipositor up against Grace’s hole. “You’re nice and loose now. You’re ready for someone to be rough with you. Scream for me, Grace.”
Rocky pushes inside and Grace does scream, loud, though muffled by the hand in his mouth.
“That’s right, tell everyone here how much you like this. That you were made for it.” Rocky starts thrusting, in and out, mercilessly. His ovipositor feels huge. It’s so, so good. “That you’re mine.”
“M’yours, haaaah,” Grace manages to say, the Eridian holding his mouth open seemingly taking a bit of pity on him and moving their claws to his neck. Rocky, meanwhile, leans further into him, gripping both sides of his hips with his claws, leaving bruises in his wake. The rhythm of his thrusting starts to speed up.
“Good whore. So good. You’re going to incubate so many eggs for me. I’m going to keep you here for the rest of your life and you’ll be full of my clutch for every second.”
Grace sobs. There’s nothing stopping him from speaking now except for the burning pleasure breaking his brain open. The stretch of Rocky’s huge tentacle scrambles any semblance of thought he might have had.
“Rocky, please,” He sobs. He can’t tell him to stop. He can’t say anything. All that comes out is something really stupid. “I love you, please!”
“Good, good, good, fuck,” Rocky curses and starts screeching words incoherent to Grace, and Grace feels his claws grip even harder onto his hips. “Say it again, now, please.”
“I luh-love you, haah,” He’s finding it hard to think. He screams out another moan. “I’m, fuh-- so, in love with you, I caaaan’t!”
“Love you too, Grace.” Is the last thing he hears before feeling Rocky’s ovipositor still, shifting and pulsing as it lays eggs into him. He wails. He feels himself fill up with his best friend’s genetic material, so sore and wet and exhausted. Rocky makes some melodic clicking noises and grabs onto his hips one last time, hard, then collapses at his feet.
The other two Eridians surrounding him all relax their grip on his limbs, lower him to the plush blanket-covered floor. The caretaker moves to stroke at his hair, whistling softly at him.
“You did so good, Grace,” the caretaker chimes, their voice beautiful as always.
“Thanks, Adrian… ugh, can I have some water?”
“Right away.” they gracefully maneuver their body to grab a bottle nearby. They uncap it and hold it up to his face so he can drink. He slurps it down quickly. “Need anything else?”
“Mm, c’mere. I want cuddles.” he says. He pulls on Adrian’s arm, who follows his directions and settles down at his side, stroking their claw against his belly. He looks down, trying to picture all the eggs that were just laid inside. “Rocky gave me so many this time…”
“Do you feel ready for the surgery yet, question?” Rocky asks from below him, stretching his limbs to climb to his side opposite Adrian. “To actually carry our eggs inside of you? It’s okay if you change your mind. The electronic incubator would work just fine.”
“Noooo, please, I want to.” Grace says, and closes his eyes to enjoy the feeling of his mates stroking him. “It’s perfectly safe, you said.”
“It is.” Adrian chimes in again. “And Grace is going to do a fantastic job as our little incubator. Even if he wants us to pretend he doesn’t want it sometimes.”
Grace flushes and hides his face with his hands. He can’t handle Adrian teasing him.
“Grace just wishes we were a different type of alien, something meaner that doesn’t let him choose. Like humans, right Grace?” Adrian prods at his fingers playfully.
“Mm, no. I’m happy you’re Eridians.” he peeks at Rocky from behind his fingers. His ovipositor has almost completely disappeared back into his carapace. “Did you have fun?”
“Stupid question. Yes, I love breeding you, Grace. It’s more fun every time we do it together.”
He grins. It’s still nice to hear that after all this time.
“Okay, let’s get Grace back home. We can bathe together and then watch over him sleep.” Adrian says, moving to push Grace to sit up.
“Whaaaa, but I wanna stay here a little longer. I’m sleepy.”
“Yes, but the lovely Eridians that helped us out have another party soon, and they need to clean up after us. Rocky and I can carry you home.”
“Okay fine!” he huffs in mock disappointment, secretly a little excited. “Please just let me put some clothes on first, this time.”
