Chapter Text
Adrian knew instinctively that something had happened between Rocky and Grace the second Rocky returned home.
“Adrian,” that lovely soprano of their mate drifting into the room as Rocky entered. “I'm home!”
“Welcome home, Rocky,” Adrian cooed, their voice raspier, darker. “Something good happened today?”
Rocky tapped their foot happily, doing a small dance.
“Mate with Grace today,” Rocky trilled, hands raised in joy. “Grace so sweet handsome cute when mating. Happy happy happy.”
“Wow!” Adrian giggled, bounding over to embrace their mate. “Three years only, Rocky such a flirt.”
“Adrian is worse,” Rocky huffed, pressing into the embrace, letting Adrian's melody vibrate their carapace. “I thought about you when I was with Grace.”
“Oh?” Adrian purred.
“I think Adrian would like!” Rocky laughed, tapping their feet gently. “Grace big pervert, ejaculate without egg sac or hole, Grace eggs everywhere.”
Adrian shivered.
“Humans are so perverse,” Adrian whistled. “Walking egg sac that ejaculates without reason.”
“There was big big big reason,” Rocky giggled. “But yes, want Adrian and Grace to mate also.”
“Rocky would share?” Adrian laughed. “What happened to sweet Rocky that defended Adrian from suitors?”
Rocky rubbed their claws together shyly, embarrassed.
“Adrian bad asshole jerk always bring up old story.”
“Adrian and Grace different, both Rocky mates. Am not greedy.”
“Normal to have multiple mates. Rocky sorry for attacking suitors in past. Adrian can have many mates if Adrian wants.”
“Grace pervert pervert pervert, Adrian help me handle.”
“Old story always relevant! But only teasing.”
“Rocky always very greedy. Lying to me again, question?”
“Also normal to only have one mate. Adrian only Rocky’s always.”
“Pervert how, question?”
“Grace want Rocky to “edge” him,” Rocky trilled. “Prevent ejaculation, keep Grace hard and ready.”
Adrian shook a little at that.
That was unprecedented in Eridian society. In the past, the Eridians that deposit eggs the quickest would always be the most advantaged - after all, it would result in the highest percentage of eggs in a mate. This rang true even to this day even after years of development and socialisation, and Eridians that laid the fastest eggs were always the most attractive (so eager for mate 🎵🎵!). Not to mention, with their aggressive atmosphere, leaving their ovipositor out for extended periods of time was just begging for an infection.
“Pervert,” Adrian shuddered. They felt their ovipositor twitch at that. “Grace big big big pervert.”
“I saw ovipositor twitch,” Rocky scoffed. “Adrian pervert too.”
“All Grace Rocky Adrian perverts,” Adrian admitted sheepishly. “Not my fault that alien so sexyhotenticing. Rocky needs to fend off suitors.”
“Already do,” Rocky deadpanned.
It's true. Ever since the dome was constructed and Grace was introduced into society as one of its teachers, he had constantly gotten letters. Fanmail. A countless number of Eridians had expressed interest in the alien - Rocky couldn't blame them, not really. At times, they resented the soundproof dome that they had constructed. Maybe if they had filled the biodome with the sounds of Rocky please! I love you, Rocky! Inside pleasepleaseplease! Grace would have far less suitors.
… No, probably not. They'd probably want him more after knowing that he was indeed an option, that the alien enjoyed the company of Eridians in that manner. Not good.
“Adrian wants to help with edging Grace, question?” Rocky purred, teasing. “I will ask Grace if amenable.”
“Yesyesyes,” Adrian breathed, notes falling from their vocal strings. “Of course. Happy to share."
“We would call that polyamory,” Grace hummed, his legs crossed as he brought a pen to his lips. “This is fascinating…”
They were seated at the low dining table and playing chess (Rocky like chess!) when Rocky had brought up the topic of Eridian relationships.
After they had first mated, Grace was worried. Rocky had mentioned that mate would understand, but what did that mean?
Rocky had already known, but the relationship dynamics were exceedingly different in each of their respective societies.
Humans mostly mate for life, and would only choose one mate of the opposite sex. This was the norm. Everything else was taboo, which resulted in many humans being ousted from their communities. It was fragmented and alien, and Rocky thought it was, like most other human things, inefficient. The male would insert genetic material into the female, resulting in a singular cell that multiples to form a singular baby.
Eridians on the other hand also mate for life. However, due to the lack of genders, everyone can mate with everyone else. Strong babies always resulted from the most varied genetic material, so egg-bearers with multiple partners resulted in the best and strongest children. Eridians would thrum together while mating, and all would deposit their eggs in the egg-bearer. Everyone happyhappyhappy together, and the egg-bearer will give birth in 3 human years to a clutch of 15-20 babies, give or take.
“Grace sad because I am not female, question?” Rocky hummed sadly.
“No, I think something is wrong with me,” Grace laughed. “Something is definitely wrong with me. I really do love you for who you are. I think I'd probably like you less if you were a woman.”
“Nothing wrong with that,” Rocky trilled, cheering up immediately. “Rocky happy.”
“... Not to say that I dislike women,” Grace continued. “I had girlfriends.”
“Rocky aware.”
“I… probably would have had boyfriends too, if anyone expressed interest. I'm not really against that either,” Grace continued again, his heart getting restless. “Maybe I just… like? People who like me back?”
“Nothing wrong with that either,” Rocky sang.
“There are so many labels and so many types of humans and sexuality that it stresses me out,” Grace choked, burying his face in his hands. “I don't know. Does it matter? Should it matter? There aren't any humans around for millions of light years.”
“Grace is rambling again.”
“Fiddlesticks.”
Rocky fiddled with their claws as Grace continued speaking, theorizing about the development of such a “unique” way of life. Rocky wasn't an Eridopologist. They don't know why their society had developed in this manner.
Either way, it wasn't a good idea to introduce a concept to Grace with science. They were getting off track.
“...Grace.”
“Yeah bud?” Grace hummed, worrying the tip of a ballpoint pen with his teeth as he circled another note that he'd just made.
“Rocky wondering if you would like to 🎵🎶🎶 Adrian also,” Rocky warbled.
The pen flies out of his mouth at a speed that shouldn't be possible under the laws of physics as Grace choked on his own spit, grasping at the surface of the table.
“Ah. Apology. I should have been more delicate with my words,” Rocky laughed. Grace was always so dramatic.
“What? What? What?” Grace stared at Rocky, eyes wide, before a hand flew to his face, fingers pinching at the bridge of his nose. “Sorry, what?”
“Adrian is loving mate,” Rocky hummed. “Adrian curious about you.”
“Oh, okay. Yeah,” Grace laughed, incredulous. “So you guys talk about me.”
Rocky nodded.
“And Adrian, whom I've never met in person wanted-” Grace coughed. “They wanted to have sex with me? Is that right?”
Rocky nodded again.
“And you two had…” Grace waved his hands. “Like. A conversation? About it all?”
Rocky nodded, but paused.
“Am I overstepping human boundaries again?” Rocky whined softly. “Apology if so. Please do not be distressed.”
“Oh, no no no,” Grace shook his head, heat rising to his cheeks. “I mean. Probably? This would probably be an overstep. But I'm not angry or distressed I'm just-”
“Is sleeping with mate’s mate bad, question?” Rocky asked.
“Well, see the issue is that most human mates don't have another mate, right?” Grace explained, flustered.
“But you just said like polyamory,” Rocky tilted their carapace in curiosity.
“I'm…” Grace trailed off. “I don't think I'm polyamorous.”
Rocky deflated at that, sad notes whistling from under their carapace involuntarily.
“Well, I'm not exactly sure, actually,” Grace sighed. “As I said, I don't think I would have cared too much about the gender of my partners... Maybe I wouldn't mind having multiple partners! But before I agree to things like that, I have to get to know Adrian, right?”
A metaphorical lightbulb flicks on in all of Rocky’s minds.
“Silly Rocky,” Rocky sung. “Grace doesn't have Eridian hivemind, so Grace never got to know Adrian!”
“Eridian… hivemind…” Grace trailed off.
“Yes yes,” Rocky whistled. “Bonded mates share many thrums, big part of Rocky is Adrian.”
Grace stared blankly at Rocky.
“I'm sorry,” He started. “I have no idea what that means.”
Each Eridian operated as a “hivemind”. Worker cells keep the individual Eridian healthy and alive, and their 5 minds each cooperate to control the main body.
Given their individual biological traits, it made sense that each individual could also combine into a larger hivemind - they do this by thrumming.
For bonded mates, a marriage ritual is made by embedding a stone into each other’s bodies. This stone was usually made with material from the mate - they swap cells.
Like this, their connection would deepen, the larger parts of their individual bodies combining into a whole. Being mated to Rocky, apparently, would already be similar to being mated to Adrian, as they are two parts of the same whole.
Grace had unwittingly been pulled into a space alien throuple and now the third member of said throuple wanted a piece.
“Okay. Okay I understand,” Grace flushed. “But uh. We humans don't work like that.”
“Understand,” Rocky hummed.
“So for some people, loving more than one is difficult,” Grace mumbled, flustering further as they spoke. “And me? Ol’ lonely Grace with no mate to begin with? I didn't even think I would love one!”
"Understand…” Rocky wilted.
“No no no,” Grace spoke, alarmed. “I mean! Anything could happen, right? I'm on Erid, and I fell in love with you! Remember? I had a whole crisis over that?”
“Eridians do not forget,” Rocky sung, before raising two hands. “Grace wants courtship,”
“Wait, no that's not-” Grace groaned, turning away from Rocky in embarrassment. “I need more time, and I need to… get to know Adrian, we need to go on dates-”
“Grace wants courtship, statement,” Rocky giggled, hands wiggling happily. “I understand.”
“I mean-”
“Rocky will let Adrian know!” Rocky stood up, giving their carapace a brief stretch. “Hope that Adrian will court Grace successfully.”
Grace could only gape as Rocky scuttled away from the table, leaving their game half finished (though that was mostly Grace’s fault for getting distracted with Eridopology). He spared a weak glance down at the chessboard - Rocky had mate in three.
“Grace, meet Adrian!” Rocky sung, raising two arms to gesture at the new Eridian in the dome.
Grace had met other Eridians, of course. Mostly while they were working on his dome, and some members of the faculty. This was the first time he'd met someone that he actually knew about, though.
Rocky loved talking about Adrian. Rocky would sing about how intelligent Adrian was, about how lovely Adrian’s voice was, and even about their day to day as mates.
Rocky had never explained exactly what Adrian looked like to him, though. This also made sense, since to Rocky, Adrian probably looked like another Eridian with the distinctive “Adrian” tattoo on their arms. To Grace, however…
Rocky was small. Their carapace was an Earthy warm Ochre. Underneath their rocky carapace where friction at their joints wore off, striations of a vivid green peek through - a material that looked like jade. After they'd returned to Erid, Rocky had gotten some maintenance on his carapace - that is, they'd gotten themselves polished. Like a haircut. The green got more vivid, their Carapace less dull.
All that Grace knew about what Adrian looked like was that Adrian’s marriage stone to Rocky was an icy blue.
He simply did not expect to be face to carapace with such a stunning Eridian.
Adrian was larger than Rocky - if Rocky were a french bulldog, Adrian would be a German shepherd. Their carapace was made of a similar material as Rocky, but they were far encased in keratin.
Exposed spots of an iridescent, icy blue mineral twinkled under the faux sunlight. Some faces were cut sharp like a diamond where others were smooth and polished, shining like a exorbitant opal. Under the brighter portions of their exoskeleton, dark striations of grey-black lined their body like stripes on an animal.
“... Isn't staring rude for humans?” Rocky questioned.
“Oh- I'm sorry,” Grace shook his head. “I’m sorry, Adrian, you are gorgeous.”
Rocky startled at that, jumping and shaking their carapace. Adrian cooed softly, a glittering arm raising to touch one of their many faces.
“How flirty,” Adrian cooed, their voice a little lower than Rocky’s. “Grace is a dangerous man.”
“Oh- No! That's not what I meant!” Grace spluttered. “You are… just objectively very beautiful. Your colours are really vivid, like a gemstone. It's stunning.”
“Rocky not beautiful, question?” Rocky fumed, shaking their body slightly.
“No-” Grace sighed, pinching the bridge of his nose. “Rocky fishing for compliment. Statement.”
“Rocky go fishing,” they twirled then, cheeky. “Adrian very beautiful mate. Rocky very lucky.”
The two Eridians purred then, nuzzling each other through their exosuits.
“Well, it's very nice to meet you, Adrian,” Grace smiled. “I'm Ryland Grace, and-”
“Adrian knows,” The larger Eridian chirped. “Rocky tell me all about you. Good good good human saved Earth and Erid.”
Grace flushed then, pursing his lips together in a meek smile.
“Rocky not kidding,” Adrian whistled, amused. “Grace easy and loud.”
“What is that supposed to that mean?” Grace raised a brow.
“Rocky said you were obvious obvious obvious, everything make you hard,” Adrian giggled. “Noisy when hard. Blood rushing loud.”
“What?!” Grace yelped, turning to face Rocky. Rocky sheepishly grabbed at the sand under their feet.
“Grace is very enticing and cute alien,” Adrian purred. “Excited to begin courtship.”
“I leave first,” Rocky chirped, scuttling away at speeds Grace had never seen Rocky move at.
“Oh-” Grace blinked, before turning back to Adrian. Somehow, he felt like he was going to be eaten up.
“I made Grace a gift,” Adrian cooed, stepping in the sand shyly. The movement was strikingly familiar, and Grace felt his heart warm. “Had some help, but I hope you like.”
“Ah… thank you,” Grace mumbled. The thought that Adrian was trying to win him over was already flustering him. “What did you make?”
Adrian shifted again, producing a canister. It looked awfully similar to Blip-B, the xenonite shell encasing what would be Adrian’s gift within.
“Am not engineer like Rocky,” Adrian hummed. “Biologist.”
“Oh yeah, we should definitely talk about that,” Grace smiled. “Rocky told me about your work. It's incredible.”
Adrian cooed at that, a low melody.
“Grace very very very dangerous man,” Adrian swayed. “Call me pretty and smart on first meeting.”
“That-” Grace flushed, grasping what he decided to call Blip-K. “I'll shut up now. Thank you for the gift.”
“In Eridian customs, open gift in private,” Adrian sang. “Will leave Grace with gift. Hope you like!”
And with a final chirp, Adrian ran off as well.
Grace stared blankly at what was sealed within Blip-K.
Opening the canister and dumping out the contents, he was shocked to see what looked like a red ball encased in a container that unravelled easily. The red ball was small, about the size of a ping pong ball. Grace had absolutely no idea what it was.
Grace eyed the ball, poking it with a finger. It was slightly warm yet nowhere close to the ambient temperatures of Erid. Of course, the canister had ensured a vacuum seal. It was very thoughtful of Adrian, or it would be if he knew what it was.
Maybe there was something more?
Grace studied the Blip-K, trailing fingers down its exterior. It looked like one of those space canisters yes, but there were also grooves etched into the grooves on the original canister. Groove-ception, if you will.
Having stayed for about four years on Erid by now, he was perfectly fluent in the written Eridian word (or at least Rocky’s language) and semi-fluent at spoken Eridian (he goes off key at times, resulting in apparently hilarious sentences).
The grooves were Eridian characters.
Grace licked his lips as he carefully traced the lines on the container.
Beautiful
Oh.
Ah, dang. Grace really was so easy. He felt his face flood with warmth yet again.
Beautiful?
Beautiful!
He was beautiful.
Or maybe the odd red ball on his table was beautiful?
Just then, his fingers reach a delicate notch on the other end of the Blip-K, much farther down.
Ah, of course. A second compartment. Rocky was right, he's a stupid human through and through.
Twisting the second compartment open, Grace blinked as a rigid slice of metal fell out. Grooves are cut into the piece, like a letter.
It's a letter. It's not like a letter, it is one.
Grace smiled, grasping the note in his hand and trailed a finger across the grooves. There seemed to be dust pigment forced into the grooves, likely making the contrast more apparent for the human. It's very thoughtful, and Grace felt his face grow warmer at that.
Adrian is trying to court him. Actually.
A small sigh escaped his lips as he traced the note.
BeautifulSmartHandsome Grace,
I WorkHard on HumanBiodomeProject, this is SideProject. I expedited since I hope you AppreciateLoveEnjoy. Understand human not LoveLikeEridian, hope you consider me as LoveSexMate. Gift is for mouth! Enjoy.
LoveYou BeautifulSmartHandsome Grace,
Adrian
Oh they are so incredibly blatant with it. Grace buried his head in his hands. They wanted him, for some absurd reason, and they were already throwing around words like love? Eridians had “LikeFriendALot” “LoveCompanyGoodPerson”, but the letter was dripping with desire that even a human that was culturally distinct could sense it.
The letter also gave no indication of what exactly this little red ball was, aside from it being for the mouth. That's incredibly scary, is it not? He's supposed to put it in his mouth? Is it a sex thing?
He cracked an eye open, staring at the orb from between his lashes as his fingers dug into the meat of his skull.
He definitely trusted Adrian. It's a no brainer - Adrian was Rocky’s mate. They wouldn't try to poison him, and they were apparently one of the biologists working on the biodome. Whatever it was, it was definitely safe.
Picking the squishy red ball up, he took a deep breath and placed it into his mouth.
Immediately, a soft and shockingly fruity scent wafted up to his nose, reminiscent of a grape.
Grace blinked.
In the time that he spent on Erid, they'd had multiple scientific breakthroughs on the development of food as well as the habitat development on the planet. Apparently, they were considering a cloning program to create other lifeforms from Earth based on the science in the laptop, too (Grace didn't know what to feel about that).
Even after years of work, Grace still hadn't tasted something that was so intensely familiar.
Biting down, a faintly bitter but still immensely sweet juice spilled from the flesh, and Grace moaned.
It's a grape.
Or at least, it's what Grace would identify to be a grape. It smelled like a grape, and tasted vaguely sweet. The flesh of the fruit was clearly made from his own muscle tissue, with fibre weaved through the complex. Little holes were added to contain juice - juice that tasted like a combination of pure glucose and what was probably vinegar.
Did they figure out fermentation? Did they harvest what little quantities of yeast was on his body while he was asleep to make wine and then vinegar? How was the fruit matrix created?
It was hard to think, because tears had sprung into his eyes.
Adrian had recreated fruit on Erid. He could kiss them.
“Adrian!” Grace lit up. “It's good to see you!”
A few days had passed since Grace had been moved to tears. Instead of Rocky, Adrian had visited him that morning.
“Grace,” The Eridian purred. “Liked gift, question?”
“Yes! About that!” Grace smiled, excited. “How did you do that? That was incredible! It tasted so much like a grape! We have to discuss this!”
Adrian jumped at his excitement, scuttling backwards.
“Loud human,” Adrian sang. “Shocking.”
“Oh! I'm sorry,” Grace looked away. “I'm just. I'm very happy, and humans get loud when we're happy.”
“Oh!” Adrian sang. “Happy happy happy.”
“I do want to talk about it, though,” Grace said sheepishly. “Can we? How did you do it? How long did it take?”
“Adrian here to bring Grace to work,” Adrian hummed, amused. “Not time for discussion, time for teaching.”
Grace groaned at that, his shoulders drooping.
“But… we have plenty of time! We don't need that much time to walk to work,” Grace pouted.
“Cute sad expression very effective manipulation tool,” Adrian shivered. “But no, is work time.”
Grace sighed, turning back into his home to grab his coat.
“Apology,” Adrian giggled. “We discuss next time.”
Grace sighed, stepping out of his home and shoving his hands into his cardigan pocket.
“Why come escort me, anyway?” Grace pondered as they walked. “Rocky always did it, and I thought he just wanted to hang out. But now you're doing it?”
“Escorting is part of courting,” Adrian cooed, teasing. “Must make sure Grace is safe.”
“Oh… is that right,” Grace felt his cheeks warm.
“On Erid in past, life dangerous. Many predators eat Eridians,” Adrian sang. “Strong Eridian mate always escort vulnerable Eridian mate everywhere. Even if safe, instinct guide us.”
“Wait,” Grace paused, turning to look at Adrian. “So you two escort me to work because your instincts are protective of me?”
“Yes,” Adrian ruffled their carapace proudly. “Will protect mate from danger. Rocky done once, Adrian will also do.”
“Oh…” Grace smiled weakly. “That's sweet.”
“Will be sweet for Grace,” Adrian hummed, low and dangerous. “Grace sweet for Adrian too?”
Grace was not used to this.
No, Grace definitely wasn't used to this.
The flirting he had experienced on Earth was subtle. It was a push-pull, where girls would sidle up next to him with an innocent smile, asking about his hobbies and interests. He blushed without fail every time, because he was pathetic, but also because it was always such a foreign feeling to be desired in that manner. He was never all that good with intimacy.
He must have gone quiet, since Adrian twitched, before continuing to speak.
“Apology,” Adrian mumbled. “Too forward.”
“No,” Grace spoke, low. “I like it.”
“Grace likes forward?” Adrian questioned.
“I… think I do,” Grace felt his eyes glaze over slightly. It was a nice feeling, he thought. “I'll be sweet for you I think.”
“Yes,” Adrian giggled. “Grace always so sweet. Heard lots from Rocky.”
Oh, he was in trouble.
“Rock-” Grace said, flustered. “Rocky told you all about me in bed, didn't he?”
“Yes,” Adrian sang.
“It's not fair,” Grace mumbled. “I don't know anything about you.”
“Because Rocky embarrassed,” Adrian said, matter-of-factly. “And you never asked.”
This was true.
“Tell me?” Grace asked, his voice trembling.
“After work,” Adrian giggled again. “I find you later, tell you all about Rocky.”
And with that, Grace looked up to see the entrance to his classroom.
Dang it.
As promised, Adrian showed up again after he had returned to his home for the day. Surprisingly, though, they had asked to move to the soundproof dome that Rocky had constructed.
“Not because sex,” Adrian assured. “If talk about Rocky, want privacy.”
And thus there they were in the soundproof dome. The scent of sex lingering in the room did not help, especially since his Pavlov'd hindbrain was roaring to go at the drop of a pin.
After their first time together, Grace became a bit of a menace. He'd whine and hum in Rocky’s direction, riling the poor thing up, before eventually being dragged to the sex dome.
“Grace always so greedy,” Rocky had hummed at him, tone annoyed as all heck - and Grace just whimpered back at them, weak to his body’s wishes.
“With me, Rocky usually egg-bearer,” Adrian spoke, cutting through Grace’s foggy mind with a knife. “You understand?”
“That-” Grace flushed. “You're the one inserting, I guess?”
“Yes,” Adrian cooed. “Rocky always needy and weak, always beg for ovipositor.”
“Please,” Rocky cried weakly, carapace tilted up, presenting their hole. “Adrian hurry.”
Their seam was cracked open, liquid metal pooling and dripping down from their body. Rocky, weak to affections, had already ejaculated - eggs stuffed deep into their sac and already attempting to overflow .
Adrian’s body shivered as their seam began weakening as well.
“Rocky always so greedy,” Adrian hummed. They reached a hand out towards their seam, tracing the entrance faintly. “Always ejaculate before Adrian ready, always so pathetic for me.”
“All for you,” Rocky whimpered, shaking as their seam quivered in anticipation. “In me, please.”
Adrian sighed at that, their ovipositor squeezing out of their seam. It was largely the same as Rocky’s, except significantly larger. This was natural, of course, since Adrian’s body was larger.
It always was a delight to fuck Rocky.
Rocky, that sweet babe, was always receptive to flirty words. Even before they became mates, Rocky was so adorable - a soft promise from Adrian and they would splutter, words stuttering from their vocal strings. At the time it was less a promise and more just teasing, but things between them shifted rapidly over the course of some short decades.
The pretty thing shook, overstimulated and weak, as Adrian began inserting.
At the start, Rocky couldn't take all of Adrian. Adrian was large, and Rocky’s sac wasn't all that large. Rocky would cry and whimper while riding Adrian, trying to press their ovipositor further into their hole to no avail. After years of sex though, Rocky fit like a glove - their sac stretched out like rubber.
Adrian sighed, feeding their ovipositor into Rocky.
“Yes yes yes yes yes,” Rocky cried, pushing back towards the ovipositor. “All in, all for me-”
“Slut,” Adrian hissed. “So loose for me now. Ruined for everyone else.”
“!” Rocky sobbed, Carapace shaking with intensity. At that declaration, Adrian felt the sac pulse weakly as Rocky squeezed around the intrusion. “All because of Adrian. Adrian too big for Rocky.”
“All because of me,” Adrian cooed. “Loose pervert Rocky, ruined by me. So pretty for me.”
Adrian hummed a low melody as their ovipositor was pushed into Rocky’s sac, the organ slick and wet inside.
“Wet wet wet,” Adrian growled. “Feels so used. Feels like others here before me.”
Rocky whimpered, their own ovipositor twitching weakly in their carapace.
“Rocky always so wet and ready for me,” Adrian cooed. “Maybe need more eggs from others, fill up nice and full?”
“No…!” Rocky whined. “Only you!”
“Now Grace also,” Adrian teased, the base of their ovipositor twitching as eggs began moving through their appendage. “Grace fill you with eggs too. Small amount. Small dick. Fit in together with me.”
Rocky’s spent ovipositor jumped, pressing against their sac.
“You want that,” Adrian growled. “So greedy. Always so greedy.”
“Want eggs from all mates,” Rocky whimpered. “Fill me, please.”
“... Should I leave?” Adrian asked, teasing.
Grace squirmed on the bed, dick roaring hard. He's nearly in his 50s, yet he was straining like a teenager that just discovered lube.
“No,” Grace whispered. “Want to know more.”
“Oh?”
“How… how big are you?” Grace flushed, eyes wet with moisture. “You couldn't fit into Rocky?”
“Not for a while,” Adrian purred. “Always Rocky fuck me to completion last time, always so sad sac can't take mate.”
“He's…” Grace swallowed. “He's a size queen.”
“Meaning, question?” Adrian tilted their body, a behaviour they had learnt from Rocky.
“He likes… he likes it big,” Grace explained sheepishly, hands digging into the meat of his thighs. “I'm not enough for him.”
“Not true,” Adrian sang, reassuring. “Your holes perfect for Rocky. Always tell me how tight you are, no matter how much you stretch.”
Grace let out a whimper, his hard-on tenting through loose astronaut pants.
“Always tell me how cute you are, stupid stupid stupid human that gets stupider when having sex,” Adrian sang. “Only one brain, start melting with little teasing. Like now.”
Grace groaned, his hands flying to press against the front of his pants.
“I should leave?” Adrian laughed, the tune melodic.
“Stay with me,” Grace whimpered as he laid back into the sheets, hands clutching at the hem of his pants. “Talk to me.”
“Took Rocky three years, only took Adrian few days,” Adrian teased, clambering up on the chair next to the bed for a clearer view. “You are slut like Rocky.”
“Fu-haahdge,” Grace gritted as he shoved his bottoms down, revealing his cock. It slapped weakly against his lower tummy, blood streaming through like a hurricane.
“Ah, Rocky was not kidding. Smaller than expected,” Adrian hummed.
“You-” Grace whimpered, grabbing at the water-based lube that was stocked in the dome by this point. “Not you too!”
“You like,” Adrian sang. “You like being small and weak and soft human for us.”
Grace felt overwhelmed tears spring to his eyes as he squeezed lube messily into his hands.
“Rocky bigger than you, Adrian bigger than Rocky,” Adrian sang sweetly. “Adrian twice as big as Grace. Will split you in two.”
A slippery hand reached down, grasping his cock in his hand. Grace whined as he began stroking, the noise of wet friction filling the space.
“Grace never makes it to Rocky’s sac,” Adrian teased. “Always ejaculate so quickly. Need us to train. Like how Adrian trained Rocky’s hole.”
“Oh-” Grace trailed off with a high pitched noise. “Please.”
“Stop,” Adrian hissed.
Without really meaning to, Grace’s hand paused as he cried out, teetering at the edge.
“Already so far gone,” Adrian clicked. “When together, we will take turns holding Grace down.”
“Please please please-” Grace cried, hands twitching as he fell from the edge. “Let me- let me move, please!”
“Use your words,” Adrian sang.
“H-huh?” Grace sniffled. “What do you mean?”
“Say Grace want to 🎵🎶 his 🎶 until 🎵🎶🎵🎵,” Adrian crooned. “Say 🎶🎵🎵 for Adrian and Rocky, want mates to 🎶🎵 your 🎶🎵🎵.”
Grace's eyes widened, his cock pulsing in his hand.
“... Only if okay,” Adrian immediately took back their words, sheepish. “Adrian always too much. Rocky is the sweet one.”
Grace sniffled, tears rolling down his cheek.
“It's…” Grace squirmed, cock pulsing in his fingers. The lube was getting cold. “I'll do it.”
Adrian perked up at that.
“I… I want to-” Grace swallowed. “I want to jerk my cock until I come all over myself.”
Adrian shivered.
“I-” Grace sobbed, shaking. “All my holes for Adrian and Rocky. Want my mates to f-fuck my holes.”
“Wow,” Adrian whistled, pleased. “Grace really want that? How perverted.”
“Please-”
“You can keep touching. Slow,” Adrian sighed. Their carapace was bulging obscenely. “Lift up your shirt and tell me you want mates to 🎵🎶 your 🎶🎵🎵mouth until 🎶🎵🎵 all filled with eggs and keep 🎶🎵🎶 forever.”
Grace cried, hands shaking as he continued rubbing himself, far slower than he wanted to.
His other hand shifted up to his torso, pushing his shirt up and above his pecs, showing Adrian what was probably only a slightly clearer view of his nipples - pink and abused by Rocky.
“I want- want my mates to fu-haahck my ass and my mouth,” Grace sobbed. “Until all my holes are filled with eggs and-”
“Faster,”
Grace cried as he sped up, his cock burning red from stimulation.
“And what, Grace?”
“And k-keep me…” Grace felt his lower belly clench. “Wet and ready for mates forever-”
“That's not what I said,” Adrian laughed. “Grace so cute, so honest when hard. Tell me what you really want.”
“Want you,” Grace cried openly. “Want to cum.”
“We'll work on that,” Adrian giggled. “You want mates to 🎵🎶🎶🎵🎵. That's what you want.”
Grace felt his body seize as a wounded cry burst from his throat unbidden. He sobbed through his orgasm, his cock pulsing weakly as his “eggs” were squeezed out from his dick.
He panted heavily, before curling up into himself, exhausted.
“You're okay,” Adrian hummed, sidling up gently to Grace, who whined. “I'm sorry if it's too much.”
“Adrian,” Grace spoke softly. “I like you a lot too.”
Adrian purred at that.
“It's not the same as with Rocky,” Grace mumbled. “But I think I'd enjoy it. Next time.”
