The idea of Rocky being sassy and talk back to Grace but magically gains manners and is a little peach when interacting with you.
It’s like those chihuahuas that are sweet little angels with owners but HATE their owners’ boyfriends. Except Rocky is a fully grown Eridian with a serious engineering job and trusted on a planet saving mission.
He’s both doing this to piss off Grace, but also because Rocky is genuinely whipped for you and even though he likes being bossy, something about you giving him instructions and orders makes him all giddy inside.
You lowered yourself onto your bed in the dormitory, pulling the bedsheets up to your chest. Both you and Grace had moved the beddings onto the floor instead of the compartments attached to the wall. You preferred the floor in fear of falling off the bed because gravity wouldn't be kind if you fell.
You turned on your side, facing Rocky.
He sat a few inches away, two of his limbs curled underneath the bottom of his carapace like he was a cat loafing. You were glad he moved out of his xenonite ball into an actual suit to cover his body.
Rocky shimmied in place. “Rocky notice your body is still active when sleeping. Why is that, question?”
You blinked in thought. “Oh yeah, I move around in my sleep. But a bunch of different reasons can cause it,” you started.
“Sometimes it’s maintaining physical comfort, regulating our body heat, or it can be tied to a sleep disorder.”
“What is a sleep disorder?” Rocky asked.
You yawned. “They’re conditions that affect how humans sleep, from the quality to the amount of sleep we’re getting. There’s different types of ‘em.”
Rocky nodded his carapace. “Too complicated. Humans too restless.”
You chuckled. “I think you’re describing Grace right now.”
Rocky tapped two of his claws together. “Grace should be sleeping soon, too. Rocky will remind and or get him if not.”
You reached your hands out towards him, a wordless cue that Rocky understood was a cultural thing.
Rocky trilled, happily trotting underneath your bedsheets to your chest. His body was like a personal little heater, given his insanely high body temperature.
You stroked the top of his carapace.
You had an urge to kiss the top of his carapace, but decided against it. He'd probably be uncomfortable about it, wondering why your mouth hole was on him. Perhaps another night you'd show him some other ways humans show affection to each other.
You let out a tired sigh. “G’night, Rock.”
Rocky shuffled closer. “Good night. Rocky hope you have sweet dreams.”
Closing your eyes, you fell into a dreamless sleep.
Grace shuffled into the dormitory a little later. He paused at the doorway, seeing you snuggled up with Rocky. He held in a coo at the sight, getting under his own bed opposite you.
He folded his glasses, putting them on the empty cot attached to the wall.
“How’s sleep watch going, Rocky?”
Rocky moved slightly, careful not to disturb your sleep. “Good, good, good. They’ve made minimal movements so far.”
And as if on cue, you flopped your arm over Rocky's vents, jostling him. You kicked your leg out from under the sheets.
Grace held in a laugh, chuckling into his pillow.
Rocky carefully returned your arm to your side and crawled out of bed. He readjusted your sheets for you.
He slumped his carapace onto the padded floor between you and Grace. “Nevermind. No understand human sleep.”
Grace patted the top of his carapace. “You know they can’t help it.”
“Yes, yes, understand that part.”
Grace rubbed his eye and relaxed under the covers. “Sweet dreams, Rocky.”
Rocky curled two of his arms under his carapace. “Rest good. Hope you have fun in other life.”
Grace slipped one of his hands under the pillow, his breath slowly evening out.
A feeling of relief washed over Rocky, content that his two humans were now asleep.
Tws: none really, Rocky is just curious about human flesh
Rocky was always amazed by how physically close humans could be to one another.
Despite their society being far more peaceful and utopian, Eridians had way more personal boundaries and rules, especially when it came to physicality and touching. Truth be told, Rocky who was quite active and energetic by nature didn't particularly like this. He craved more physical contact and affection. That was part of the reason he chose Adrian as his mate a large, strong, and beautiful individual so she (i refer to Adrian as she, vc i LOVE this small sunshine husband and big calm wife trope) could "hug" him with her limbs much more.
So he always loved watching how you and Ryland hugging and generally just being physically affectionate with each other. Ryland is surprisingly touchy as well.
He "saw" the softness of human flesh, (especially yours) through the vibrations, through the way sound "bounced" off you just a bit softer, particularly from your chest and hips.
He desperately wanted to touch you all over, but he didn't know if that was acceptable in human society, and for now, he was still too shy to ask.
bimbo!reader that's on the hail mary not because she’s some genius astrophysicist or strategic mastermind (nope), but… well, honestly? she doesn't even know how she got picked. maybe it was luck. maybe they needed someone “motivational.”
ryland grace sees right through it. the second he lays eyes on her; bouncy hair, glittery lip gloss, that lost smile... he doesn’t hate having her around. in fact? he kinda relies on her dumb little face being there every morning at breakfast with a sunshine grin. it keeps him sane when space isolation starts eating at his brain like mold.
ortiz!rocky sends blip a to the hail mary, their first ship-to-ship communication and when the alert pings? her eyes go wide with unfiltered joy. she squeals so loud ryland jumps, and without missing a beat, she shouts: “we have neighbors now!”
bimbo!reader who adapts insanely fast to having an actual alien as her roommate. when rocky arrives and asks excitedly “where my bedroom?” her wide eyes sparkle and without hesitation she beams; “you can sleep with me!” rocky nods so hard his head might’ve popped off. he doesn’t understand human mating rules… but this girl is inviting him into her bed, to watch her sleep. his heart does a little flip.
bimbo!reader that unbeknownst to her, she accidentally starts a silent competition between the two males. every time she leans into rocky needing him to fix something, every hug she gives him or a chaste kiss on his cheek... ryland clenches his jaw slightly tighter each time. and when she turns those soft eyes towards ryland instead; bringing him coffee when he's tired or plopping down beside him during movie nights, the reverse happens: rocky feels like ryland’s courting his mate in front of him.
bimbo!reader that starts accidentally helping them bond… without meaning to. one day rocky “trips” near her, knocking over her open notebook on the floor. just a clumsy bump, but when she bends down to pick it up? her skirt rides up just enough that both guys catch an eyeful: soft lace panties with little stars peeking out for half a second. they both look at each other with a silent mission on their minds.
bimbo!reader who is accidentally pushed straight into rocky’s lap. she yelps in surprise, but lands perfectly snug against him, his arms instinctively wrapping around her waist for balance. and she doesn't notice anything weird when she snuggles right where he has an obvious tent forming beneath his sleek pants from having a pretty girl pressed right on top.
bimbo!reader who starts to want both of them without realizing to. she also became nervous for the loneliness, and even a nice girl like her has urges. so she may or may not start to touch both of the guys in the hail mary.
bimbo!reader who accidentally bit off more than she could chew. now there's an eager rocky with his dick pressing right against her ass, slowly sliding up and down, teasing through the fabric. her panties are already damp, soaked really… and that delicate lace doesn't help at all. if anything, it makes everything worse. every little brush feels electric, and every nerve of her is screaming for more friction.
bimbo!reader who feels a sudden tap at her cheek and a gruff “open,” from ryland. she sticks her tongue out, eyes half lidded. ryland starts to slide down his dick inside her mouth. “f— f— fudge…” her lips glide over every thick vein on his shaft, tongue pressing softly as she takes him deeper. her nose nudges right into the soft hair at his base. she bobs her head up and down, trying to milk him for all he's worth.
bimbo!reader hears rocky hum low in his throat, watching her with dark amusement. he suddenly pushes two thick fingers against her pussy lips still covered by her panties. she whines against ryland’s cock, spit blabbering down from her mouth. rocky presses his dick harder, and she feels the way his eyes are fixed on her pussy. he groans, “pretty. pretty. pretty. the most pretty mate.” she swallow at his words, making the pressure in ryland’s cock harder; she hears the way he whines when he comes deep inside her throat.
bimbo!reader who swallows hard, milking him. when she finally lets him go, she opens her mouth and shows ryland the way she drank it all up. rocky is still dragging his dick against her slit, over and over, making her whine. “it’s so big,” she says. “i don't know if it’ll fit.” rocky leaves a trail of wet kisses against her tummy, all up to her neck. “rocky will make it fit.”

!!! MIND THE TAGS AND MINORS DNI !!!
The first thing Ryland heard when he opened the front door to the beach house was the sound of something wet.
Something wet with a little bit of suction, like someone was pulling their hand out of a wet rubber glove.
And it wasn’t just one odd noise. The noise was constant. A continuous, repeating rhythm of wet schlorp’s sounded through the home.
Ryland had been out teaching all day. It had been an especially grueling lesson on Earth animals, which his students found extremely fascinating. They were rambunctious and chattery, even more so than usual, and it was near impossible to wrangle them. Very little teaching was accomplished and now Ryland was ready to kick back, relax and give his brain a break.
After he found out what that noise was.
Bunching his brows in confusion, Ryland quickly shut the door. He considered yelling your name but he decided against it. You were obviously here, there was nowhere else for you to be, so you must’ve been the one making the noises, but he just didn’t know what you were doing that could make such a noise. Washing the dishes maybe? Cleaning something? He couldn’t help but think that the noise sounded familiar, and in the couple of seconds it took to toe off his shoes, he had a hunch.
Shrugging his cardigan off his shoulders, Ryland hurried to the living room where the sounds seemed to be the loudest. His cardigan fell to the floor and his jaw dropped alongside it when he turned the corner.
You were home alright, alongside the two other members of your family- your mates, as they insisted you and Ryland call them. Rocky and Adrian had decided to stop by while Ryland was gone. And, apparently, they couldn’t keep their claws to themselves.
Adrian sat on the floor- a looming presence in the room considering their sheer size. Ryland often thought it was a miracle they’re even able to squeeze through the front door. Adrian was using three of their arms to tilt themselves back enough to expose the ventral seam on the underside of their carapace, which was gaping wide, oozing silver and had a long, meaty appendage snaking out that ran up and disappeared in your ass.
Adrian’s ovipositor was a deep, navy blue and almost three feet long when fully unfurled. Obviously, only a fraction of that was used during sex with you and Ryland, but the girth of it wasn’t any less intimidating. Ryland still struggled taking it when he and Adrian partnered up.
The first time seeing the sex organs Eridians carried was terrifying and a little off putting. Rocky had been a nice, gentle introduction to the appendage on the Hail Mary- only sporting just over a foot of length and on the skinnier side. It was something you and Ryland could handle after minimal preparation and found to greatly enjoy it with time. Once on Erid and seeing what your new gigantic mate had? It took a while to get used to.
You were next. Held in Adrian’s two remaining arms, the large turquoise Eridian held you against their carapace, your back pressed to the hard rock while their claws clasped under your knees to pull them back and spread your legs wide. A position one might find themselves in while giving birth. Except you most certainly weren’t giving birth. You weren’t even touching the floor, body suspended a foot away from the tile thanks to the strength of the Eridian behind you.
Rocky completed the Eridian sandwich at your front. Two of his legs held him upright, lifting his carapace just high enough to be level with your pussy. Rocky’s ventral seam, which was also open and exposing his fleshy interior, pressed nearly flush with your sex. Ryland could only see about an inch or so of space between the two of you, and could only see a tiny portion of Rocky’s meaty pink ovipositor, but he could guess where the rest of it was hidden.
The two Eridians were harmonizing together in such a way Ryland couldn’t understand what they were saying, but they were undoubtedly speaking praises to you.
You looked absolutely exhausted.
Pinned between the two, it was obvious the three of you had been at it for a while. The silvery fluids splattered between your legs and your overwhelmed, pinched brow was also a big tell. As the two tentacle-like organs with minds of their own battered your holes, the rest of your body wasn’t left alone either.
The blue claws that kept your legs spread were gently kneading the flesh there, a constant pulse of pressure to your thighs courtesy of Adrian. Human’s squishy, fleshy bodies still enamored your mates; they found any chance they could to hold, knead and press against yours and Ryland’s softer bits.
Rocky was also kneading your skin with a claw, focusing on your stomach this time to feel the softness and the slightly raised protuberance where his ovipositor curled inside your cunt. His second free claw was pressed to your tongue, coaxing drool from your lips to wet the rock while his third claw rubbed rough circles over your clit. Your mates knew you derived most of your pleasure from stimulation there, so they made it a point to make sure the bundle of nerves wasn’t ignored.
Ryland popped a boner almost immediately.
In the almost year of being mates, this was the first time he’d walked in on such a scene. It wasn’t the first time he’d sat out while you had your fun with Rocky and Adrian, that had happened plenty of times, but Ryland was always there to watch. Something must’ve happened to get the three of you so amped up that you couldn’t wait until he returned home.
Rocky and Adrian seemed… much more passionate than they usually were too. They usually tried to be very cautious with their fragile mates but that didn’t seem to be the case today.
Ryland took only one step towards the trio before Rocky’s familiar trills demanded something from him.
“No. Grace stay away until mates have finished.”
God, he couldn’t even get closer to watch??
Ryland was stuck on the sidelines, watching the obscene fucking happening in his living room and not able to do a single thing about it. He wanted to come to your side and kiss you stupid- he wanted to take your chest in his hands and give your peaked nipples some attention. Your eyes had been screwed shut ever since he walked in, a stream of garbled moans escaping you at the undoubtedly overwhelming rush of pleasure you were receiving from every angle. He wanted to be a part of it too but apparently he wasn’t allowed. Ryland just resorted to palming himself through his pants.
A couple of minutes passed before a visible shudder ran through you and your head flung back to knock against Adrian’s carapace. That couldn’t have felt very good but you made no indication you’d even felt the pain. Your legs seized around Rocky’s body, toes curling as the two Eridians prolonged your orgasm with their prehensile organs and rubbing claws until you finally began to slump, muscles relaxing.
You and the scientist learned the hard way that Eridian’s stamina was much more impressive than a human's. It took several orgasms (or the Eridian version of an orgasm, anyway) for them to even begin to feel tired. The true peak to an Eridian’s pleasure was during a mating season of sorts as a mated pair (or group) prepared to lay their eggs together. Their sex organs became extremely sensitive to stimulation. It was a sacred time for Eridians and one that only came around every couple of years.
Ryland suspected that time was approaching. He noticed a couple of days back that Rocky and Adrian became much more… clingy than usual; overly physically affectionate and touchy. Rocky would rub against your legs like a cat, winding an arm around your thigh to stroke the flesh and make you trip over your feet. Adrian wanted to have the two of you in their arms as much as possible. For the past three days, both Ryland and yourself woke up in the cradle of their arms instead of the comfort of your bed as they watched you sleep.
Walking in on a scene like this just solidified to Ryland what he theorized.
For the first time since Ryland joined the stuffy room, the thrusting slowed to a stop. The ovipositors stuffed inside you stopped their visible pulsing. Your chest was heaving in the air, breath ragged as you fell limp. The metallic fluid that dripped out of your core when Rocky slowly retracted his appendage (with some difficulty, as the organs had a nasty habit of trying to stay seated) fell in rivulets down your slit, splattering on the living room floor and painting it silver.
You whimpered when the almost foot long of soft, pliable flesh slipped free of your heat, leaving you empty and raw. Adrian made no move to retract theirs from you, but they did ease up their hold on your knees, cradling you against them a bit more comfortably to give your tired legs a break from being in such an uncomfortable, exposed position.
“Couldn’t have waited for me, huh?” Ryland grumbled, tugging his t-shirt off his body.
Both Rocky and Adrian chirped a firm, “No.”
Ryland looked at you with concern. You were slumped against the turquoise rock, eyes still closed and breath beginning to even out. Just how long had you three been at it? Judging by the state of your pussy; swollen and red underneath the smattering of silver and milky white release, he could only guess.
Rocky skittered up to Ryland’s side and tugged on the leg of his pants.
“Ready for Grace to join now.”
With Rocky’s unneeded help, Ryland was bare in no time and finally took the brief opportunity to kneel next to you, brushing the damp hair from your forehead. Your eyes peeled open and you gazed up at him
“H-Hey baby.” It was the first time you acknowledged that Ryland was even in the room.
“Hi, sweetheart. You look tired. How many times have they-”
“Mate achieve sexual climax seven times,” Adrian hummed, arms lifting you a little like they were proud, claws gently stroking your calves.
Ryland choked on his saliva. “Seven?”
Rocky pressed close and lifted his carapace higher, like he was proud too. “Yes.”
“Guys, humans need breaks-”
“Mate never said word,” Adrian chirped. All of you had a safeword just in case your couplings became a little too overwhelming and someone needed to take a breather. Apparently, you hadn’t deemed it necessary to say it. Or maybe you were so fucked silly, you couldn’t remember what it was.
‘Did give breaks’ is what Rocky chipped in. You lifted your hand and pinched two of your fingers together with a millimeter of space between them. Little breaks, is what that communicated to him. Probably barely a minute a piece.
“Ok, well I think we should wait before-”
“No. Must do now. Statement.” Rocky began trying to herd Ryland between your relaxed legs, which was commonly where he wound up when all four of you were having sex. Ryland brushed him off.
“Why?”
Rocky seemed hesitant to answer, and Adrian chose to stay quiet. “...just must.”
“Is it that time of year that you told us about? The egg season, or whatever you call it?”
The shoves from the brown and light green Eridian became firmer and Ryland had no choice but to move where he was pushed. Rocky was incredibly strong. The blond knelt between your legs, Adrian lowering you close enough to the ground so you were almost sitting. The looming turquoise being kept you slightly elevated, given the girthy protuberance still buried up your ass. It wouldn’t be very comfortable for either of you if you sat on it.
“Yes,” Adrian finally answered. “Clutches almost ready. Want mates ready to receive them.”
“Woah, woah! Time out!” Ryland made a T with his hands. Adrian’s carapace tilted at the gesture. Rocky made an annoyed noise. “We still need to have a discussion about that! We haven’t agreed to house any eggs.” You didn’t look like you were listening to a word he said, instead looking like you were about to fall asleep. “Besides, your clutches don’t need a host to thrive, they’re just fine staying in a regular nest. You guys want to include us in the process which is sweet and all but… can’t we just babysit them or something?”
“Could. But clutch much safer and warmer in mate.” Adrian seemed pretty set on this idea. Ryland wanted to argue that human bodies were not warm compared to an Eridian, but someone was getting impatient.
Claws shoved against his back, knocking him forward to nearly topple onto you. He stopped himself with his hands just in time, planting them on Adrian’s carapace. Their body thrummed at the contact. You blinked up at him with a smile.
“Do you need to switch positions, sweetheart?” Ryland whispered. “Or need a pillow or something for your back?” Adrian wasn’t very comfortable to lay on without some sort of padding, especially when naked.
You shook your head. “I’m ok. I’m more comfortable laying like this anyway. It hurts to squish my face into Adrian if I turn onto my stomach. I can last a little longer.”
If you say so. Ryland took great care when he guided his tip to your drooling cunt, being as gentle as possible as he slid inside. Your throat bobbed but you didn’t protest, only sighing through your nose with a grunt. Compared to Rocky, Ryland’s dick didn’t hold a candle. He wasn’t small by any means, but he also wasn’t a foot long and have a cock that could twist and curl against your walls. You weren’t complaining though.
Speaking of Rocky, he didn’t waste any more time to press Ryland’s torso closer to yours in order to bare the scientist's ass to the room.
One thing Ryland still couldn’t get used to, even after a year and then some of having this weird, gross alien sex, was the heat. Eridian’s ovipositors are hot, and every inch that snakes into you is an inch of fiery warmth that could become borderline uncomfortable at times.
Ryland’s forehead hit your sternum as he felt the molten heat beginning to creep through his intestines. Usually, Rocky would take more time to get Ryland prepped but given how wet Rocky already was thanks to you, he slid in easily.
Once Rocky was fully seated and Ryland could feel the bumpy underside of his friend scrape against his ass, the Eridians didn’t hesitate to start rutting, tearing moans out of your throats. Ryland didn’t have to thrust into you at all, Rocky’s pistoning doing all of the work for him by moving his hips to and from your pelvis.
Your hands, which had been gripping the turquoise arms that kept you elevated, moved to tug Ryland’s face down into a sloppy kiss. There was no gentleness to it, just a desperate clashing of teeth and tongue. You swallowed Ryland’s yelp of surprise when he felt a claw clamp around his balls. Rocky’s small hand rolled the heaviness between his rough fingers, fondling the sack and coaxing the first odd spurts of cum from his tip. Your gummy walls squeezed around his shaft and Ryland could feel the rhythmic drag of Adrian’s ovipositor against your walls from the inside.
It was hard to feel where Eridian began and human ended.
Your feet hooked around Ryland’s waist to squeeze him closer, a strangled sob escaping you when the coarse pubic hair at his base scraped against your raw clit. Ryland kissed your tears away.
Ryland came first. With your heat hugging him so tightly and Rocky’s ovipositor twisting and writhing deep in his gut, bumping erratically against his prostate, he had no chance of lasting more than a couple of minutes (the Eridians always complained that humans cum too fast). While he filled you, Adrian came next. You felt them pulse, quake and another fresh load of hot, silvery fluid filled your ass. Your vision turned white soon after and your depleted body found a weak, pathetic finish.
You presumed Rocky eventually finished after a couple of pumps because you felt Ryland’s navel get warmer against yours and he groaned against your jaw. The four of you sat, soaking each other in and coming down from your combined highs. Ryland was the one that moved first.
“Alright, (Y/n) is tapping out. I’m tapping out for them.”
“What mean tapping out, question?” Rocky asked, bracing his claws on Ryland’s hips to pull his vent away. His ovipositor tried everything in its power to stay buried but with some tugging and a wet shlop, the organ fell free and plapped to the floor. A rush of silver followed.
Ryland gently eased his cock from you. “They’re done for the day. They need rest.”
There were some low grumbly notes of protest.
The blond sat back on his heels to help you stand but Adrian beat him to it. The big Eridian softly pulled the navy ovipositor from you and the rush of shimmery cum that followed was immense and sticky. Cradling you in their arms, Adrian stood and brought you to the corner of the room where a giant makeshift nest lay. When the Eridians wanted to stay in the beach house instead of leaving the biodome, that’s where they bunked. They said the eggs they lay will go there too. Apparently, Adrian wanted you in there for the time being.
“Such good mate, get rest now. Ready for eggs very soon,” the alien cooed. You didn’t have the energy to argue.
Nestling you into the pile of Eridian and Earth fabric replicas, Adrian tucked you in all nice and cozy with a deep, resonating hum of song before turning to scuttle back to the two sitting in the middle of the room.
Ryland watched your eyes seal shut in exhaustion and gulped when Adrian scooped him off of the floor.
It was his turn now.
alright everyoneeee get up and get dressed, it’s time to go to church! I really made up some total bullshit about eridian mating culture and biology for this. inspo for the anatomy came from this tumblr post and this reddit post! team huge adrian forever btw, this is an art piece for reference on how big I picture them! as always, thank you for reading :)

hhmm now that i'm dusting off this blog, i may start sharing more loose ideas as well
imagine, if you will, crafting things with Rocky, with tools similar to his own for engineering work . maybe he has a spare set, maybe he makes you some– either way, while sitting with him one 'evening', you find yourself fully absorbed in watching him work . seeing him in his element, weaving xenonite together with practiced ease, it was delightful to see . the work itself also looked fun, and you voice these thoughts aloud-
Rocky pauses, tilting his carapace toward you. "You wish to learn, question?" The text-to-speech voice rings out, and you give a nod. "I mean, yeah! We've got a lot of time on our hands out here. If you happen to have some extra tools, and you're up for playing mentor, then of course." Now, you're not actually sure if it'd be possible for you to craft with xenonite– but, the idea is still fun to think about. Maybe you could turn the tables and make him a little figure, as a gift.
Rocky trills, seeming delighted by the notion, and he starts fluttering about his workspace. "Happy, happy, happy! Rocky will make lesson plan." By that point, he seems rather distracted, and in between his hurried working, he ushers you away to get food after realizing the time, long before you do. ("Grace is eating– disgust– that means time for you to eat. Go, or Rocky get Grace to move you.")
The next day, not even an hour after you've woken up, Rocky is rushing you along, while Grace watches on from the side. He's got this smile, like he knows something, and you narrow your eyes at him (to which he raises his hands in mock surrender, saying "I haven't done anything– I just think it's nice to see him so excited about something") before Rocky is calling your name, already down the hallway.
Upon reaching his workshop area, you see what all the fuss is about it: on one of the ship's tables, lie a pair of oddly shaped gloves– your size, with pieces akin to a tattoo gun attached to each finger, and it takes you a moment to realize; these are Rocky's tools. Or, something similar. Regardless– these are his tools for working with xenonite.
Your heart skips a beat. While you're aware that he's always true to his word, you still weren't expecting it. "I– you actually put this together for me?"
Rocky can practically feel your excitement; hands fidgeting slightly, as though to hold yourself from reaching out just yet, attention fully drawn to the items on the table, but the absolute joy radiating from you– your very being seems to sing, and it settles over the room like a blanket, warm and enveloping.
He finds that he quite enjoys your song, and would do anything to hear it more often.
"Yes, yes, yes, Rocky prepare tools and lesson. We will start now, statement."
Later, Grace peeks in the room to find you both set up on the floor, huddled together and weaving the threads of metal into shapes. Rocky is switching his focus between a few different things, as is his multitasking nature, but he always returns to you and your progress. You're absolutely beaming once you finish crafting your own little sphere, and though it's a little wobbly, the lines uneven, it doesn't dim your passion. You hold it up proudly, spotting Grace in the doorway, and showing it off to him. He commends your work with equal enthusiasm, but truthfully, he was more focused on the big, bright smile on your face, and the sparkle in your eyes.
as said in Matthew 7:7-8, "ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you..."
my first attempt at writing a threesome about Grace x Reader x Ortiz!Rocky. this is just straight up filth, like almost everything that i publish on this blog. enjoy, my freaky parishioners, specifically the anons who requested this. [MDNI]
I hope you’re ready to become a specimen to be studied because that’s exactly what’s gonna happen once Rocky lays his eyes on you. You're no Eridian; he doesn’t know your biology that well, and Rocky being Rocky… he’ll be curious about everything. He'll ask you about every bodily function you have and how it works; he’ll ask permission to touch you maybe during the first few days, but after that, he’ll decide on his own that you’ve become “comfortable” enough with his inquisitive nature that you’ll just be down to answer any query he might have about your body.
Grace tries to mediate between the two of you. He was sort of sore with jealousy at first when he realized that he might have to share you with Rocky, but he really isn’t the type to not budge when Rocky asks for something — what Rocky wants, Rocky gets — well, he should learn how to share, really; but Grace will teach him about that too. He knows he’s got a bit of an advantage here; you’re both human; you’re more comfortable with Grace, and he knows how to navigate situations that you two find yourselves in. Perhaps not as well as when his head is spinning while you two are making out in the lab after you’ve both bared your feelings to each other… He’s like Rocky in this sense; he’s still trying to wrap his head around the fact that you like him back. He'll come around.
The first batch of questions from Rocky is quite tame: “what this body part for, question?”, “why have protruding muscle in feeding orifice, question?” — but you’ll find out right away that Rocky is touchy even in that earlier stage. You once had to spend at least five minutes explaining why he can’t just tug at your tongue so he can get a better look at it, or that he can’t have you sit on his lap so he can study your scalp and find out how your hair is attached to your skin. So Rocky negotiates, and you end up perched on one of the lab benches as he stands between your thighs, parted just enough so he can be as close as possible to you. Rocky is, by no means, rough: he knows through Grace that you’re equally fragile, so he does his best to be gentle. He'll ask you to lean into his palm as he examines your face, knowing you’ll get tired from holding one pose for an extended period of time.
But even with all of that tenderness, he’s still got that glint in his eyes while he explores you. It's a strange, arousing mix of his curiosity and some kind of hunger, because really, Rocky wants to know how you feel against him; how you’d feel on him, around him, especially in this human form he’s taken. he’s so taken yet still so appalled by how much fluid the human body makes for specific reasons and situations, so that’s the experiment that he wants to conduct next. It'll be easy, he’d think. He has Grace to guide him through you.
The set-up goes like this: you’re laying on the mattress that they’ve set out on the dormitory floor — bare from the waist down — with your back resting against Grace’s chest as he holds you from behind, reassuring you that he’ll tell Rocky what to do, and that there’s nothing to worry about. Rocky, ever the eager individual that he is, has his palms spread atop your thighs, already giving the plump flesh little squeezes; even after all this time, he’s unable to fathom how soft you are; so abundant with curves and openings that he could sink into you every day if he wants. So, so warm, and so, so slippery against his own skin.
Rocky begins with your mouth, as always. The Eridian-Human disconnect regarding the attitudes toward eating has long been a favorite source of humor for the three of you; however, in this case, Rocky cares more about understanding why you’re gushing down south as much as you were producing spit around his fingers as he thrusts them into your mouth. he presses on a particular spot on your tongue, and you moan around his digits. Your eyes flutter shut, lips closing in around him as you suck. Grace runs his hands down your trembling arms, traveling up your sides and catching the curve of your breasts. He tells you to relax, and it doesn’t take much of you to do so, as you’ve associated the sound of his voice with comfort already. you don’t miss how his cock twitched against the skin of your lower back at all, though — you have half a mind to reach behind the two of you to stimulate him, but you put that thought aside for now.
Rocky watches intently as he continues prodding into the wet cavern of your mouth. His other hand steadily creeps down to brush against your folds, and you make that sound again; only louder this time, and this pulls an overjoyed purr of a laugh from Rocky. He withdraws his fingers from your tongue to focus on your pussy. The shame of missing him against your lips washes over you, but that’s replaced by the bolts of pleasure he gives you as he gathers strings of slick that you so generously made for him: glistening nectar from the fruit of his labor. he lays prone on the mattress, all inhibitions and courtesy of asking permission cast aside when Grace verbally tells him it’s okay to lick — he should, actually, because Grace knows you’ll like it. Rocky sings as he gets a taste of you, and you shiver at the feel of his tongue running up from your seam to your clit.
Grace snakes a hand over you and uses his fingers to spread you open, presenting your clit to Rocky. You gasp at the cool air of the dorm hitting your sensitive skin. “This is called a ‘clitoris’,’ he explains. “it would make [name] feel really good if you touched her here, Rocky.”
You brace yourself as the Eridian stares at your sex, mulling over whether he should use his fingers or his mouth. he asks Grace this, and he’s told that either would feel nice. So Rocky tries with his fingers first, and your back arches against Grace as he rubs up and down, and up and down your clit, stimulating the nerve endings like he was setting fire to all of them. He looks up at you from between your legs, elbows supporting his upper body as he smiles at you with so much of that innocent wonder he has about human biology, even if what he was making you feel was anything but innocent. He’s even more delighted when your whimpers come out in jagged succession; he’s switched to drawing slow ovals over your clit now, and you’re sure that you’re about to come in the next few moments. When he brings you there, Rocky is quick to catch your release with his mouth, much to your surprise; he laps up everything and tastes it intently on his tongue. He decides that he likes it.
Grace gets the privilege of penetrating you first. He kisses you as a reward for being such a sport for Rocky’s bit of the “experiment”, and also as a way to get his fill of you. He places you in supine, sliding a pillow beneath your lower back to ease you off the flat surface of the dormitory floor, and positions himself between your legs. He has to demonstrate this part to Rocky first, not wanting him to hurt you on his initial inexperienced trial. Having been fingered and eaten out, you accommodate Grace easily. He bows his head as he slips inside of you, the glide only making him feel closer to the edge. He wills himself to hold that back, and starts to thrust, all while telling Rocky that this is what he’s supposed to do: begin with a slow pace, have patience, and ask if he can do more later on. You’re none-the-wiser to Grace and his diligent teaching methods at this point, because all you can really focus on is how good each drag of his cock feels against your walls. Your hands switch between holding onto his arms, sides, and thighs for support, or anchor to reality; it’s hard to think rationally when your dirtiest fantasy is finally happening to you, with the addition of a very, very excited Eridian who wants to experience you in the same way, too.
You have to hold onto the sheets when Grace snaps his hips into you; a result of your own doing, since he asked you if he can go faster. He leans forward, closer to you so he could kiss you, and your legs wrap around his waist to draw him nearer. Rocky whines from the compulsion to be in contact with you again; he’s been stroking himself for the past couple of minutes, so when you briefly snap out of the haze that you and Grace were sharing, you beckon him towards you. He rushes to your side, and lets you wrap your hand around his cock to touch him yourself. His body curves forward; his fingers grip your wrist, steering you so you could stroke him the way he wants you to. Grace finishes at the sight of both of you — his hips pummel into you erratically as he fills you up, sighing as he empties himself within your addicting heat.
Rocky practically positions you according to his preference like a doll once Grace tells him that it’s his turn. You hold onto Grace as he sits up against the adjacent wall; your body’s bent over while Rocky is on his knees behind you. Rocky is a little bigger than Grace, you find; he’s stretching you more as he slots himself into your cunt, and remnants of Grace’s release drip out from where you’re both connected. Rocky wants to do that too; to give you his own release, to feel it wrap around him and paint you inside with it; and he wants to do it without Grace’s help next time. He’s a fast learner, and he aims to do good. It’ll be his first practical test, and he only needs you to tell him how well he’d do.
You don’t even get to savor the struggle of keeping your jaw from hanging slack at the feeling of being so full of Rocky, because he’s decided on his own that you’re ready to take him in such a brutal rhythm. He dips down to wrap his arms around you as he resumes that same tempo.
“[Name] feel so good; good, good, good,” he trills into your ear. He licks the shell of it, and chuckles brokenly. “Can [name] promise [name] will do it with Rocky only later? Want to get you alone, want you all to myself…”
Grace kisses you, swallowing your noises as Rocky plunges into you over and over again, catching you as your arms begin to give out. He croons, telling you that you’re doing so well while he’s pumping his own cock at the same speed as Rocky who’s fucking you in wild abandon.
You announce not long after that you’re going to come again, and Rocky is more than happy to be the one to bring you to another exquisite peak.
“Yes, yes, [name], come for Rocky one more time,” he coos into the damp skin of your nape, “wanna hear you sing again, please, please, please…”
You cry out his name as your second release rips through you, shaking in his embrace as you fuck back into his cock in faltering pulses. Rocky takes it all, and sighs as he does the same, spilling every drop within you like he always wanted. He presses his cheek against your shoulder, panting from exhaustion and satisfaction. You’ve got yours on Grace’s, and he’s dotting your forehead with gentle pecks. You tiredly lift your head, meeting his lips in a sloppy kiss.
Rocky is just about to figure out that he likes being sheathed inside you like this. Maybe he could get away with that before he fucks you again in a few hours.
grace & you becoming mates w/ rocky & adrian (however you wanna picture them) BUT you have no clue
yall are chilling on erid all happy with them and reciprocating their advances (even telling the other eridians you see about it and they say nothing about it)
then suddenly a pebble/young eridian just goes "you have been courting savior rocky and mate adrian long time! when official, question?"
and Grace is so confused so he listens to all the information he can (instead of books I would like to think they have some sort of record) and questions rocky on it and rocky pretends to be clueless why adrian is upset cause rocky said that they informed grace & you on the process
anyways: yall end up a poly group and you and adrian are tormented by those two sassy and bratty beings
