please check OC sheet for reference before you read! template not mine.

hello PHM fandom :) i was debating whether or not i was going to release this, because this is meant to be a fragment of a much bigger body of work that i plan to work on after i finish the current longfic that i’m writing for another fandom, but what the hell; when filth demands to be written, i must answer its call and deliver accordingly. i’m no good at x reader fics, and i like to have a controlled environment when writing so i used an OC that i’ve had on file since 2020, and tweaked some stuff about her.

this was inspired by a tweet (that i can’t, for the life of me, retrieve anymore) about Eridians having body jewelry as their version of lingerie, AND another post that (i can’t remember if i saw it on here or on twitter) talked about Eridian family crests. these stuck with me and i just had to write something about it.

rating: E (MDNI)

contains: penetrative s e x (p in v), multiple orgasms, vaginal fingering, handjob, cunnilingus, overstimulation; (noisy) jewelry as lingerie, established relationship (Ryland is married to OC); post-canon, headcanons about Eridian weddings and matrimonial customs (i’m just making shit up)

summary: whereas humans preferred skimpy pieces of innerwear made of satin, silk, leather, and spandex, Eridians clad themselves with jewels meant to produce dainty clinking sounds to arouse their mate (or mates) and prepare themselves for reproduction.

title is from a Björk song.

Sei and Ryland’s wedding on Erid had lots of attendees; well, at least as many as the beach inside the biodome could accommodate: Sei's Eridian colleagues at the university, her students, the scientists who played a great role in nursing her and Grace back to health when they arrived; Ryland's students and their parents, and of course, Adrian and Rocky.

The biodome was decorated only with iridescent crystals fashioned into pillars with geometric wisteria motifs; the latter chosen specifically to please Ryland and Sei's sense of sight. It was not an Eridian custom to dress up wedding venues at all, but given that the couple was of the Sol system, they allowed for this significant adjustment to be made.

The main ceremony, after Sei walked down the aisle towards a crying (leaking) Ryland, exchanged vows and xenonite rings, was the engraving of their kamon onto their shoulders, much like the gems embedded onto the legs of married Eridians. This was how Sei introduced herself to Rocky, after all. It was only right for her to update the kamon to signify her new conjugal family on Erid, and to have it forever etched on her body.

Sei took the liberty of designing the crest with the 3D printer so the Eridians could "see" it and be able to replicate it for them on their wedding day. Rocky and Adrian were granted the honor of engraving the crest after their human rituals. Rocky did Grace's, and Adrian, Sei's. A balm developed especially for human skin was applied onto the marks before being bandaged. It was so that the tattoo could heal rapidly and the skin would be left with the lines that had been drawn.

Gifts were also part of the occasion. With the exception of the jointly owned presents, Ryland proudly narrated to Sei everything that was addressed to him while she got ready for bed that night after a tiring day. The scientists gave him a functional Earth globe; a chain for his glasses from his students, and other various Earthly items intended to make him feel closer to his old home.

Sei also had her chance to do this, but not to the extent of her husband's little show. She had to leave out one item because, according to the giver (Adrian), it wasn't supposed to be just presented like a normal gift. Not like Earth-planet gift. Must only show to Grace when Sei and Grace both ready, they said, ending their private conversation with a series of sounds meant to mimic human chuckling.

Whereas humans preferred skimpy pieces of innerwear made of satin, silk, leather, and spandex, Eridians clad themselves with jewels meant to produce dainty clinking sounds to arouse their mate (or mates) and prepare themselves for reproduction.

So here was Sei, standing nervously in front of the shiny, crystalline bathroom mirror as she finished putting on the earring to complete the look. Universe be damned. The Eridians also had their own interpretation of a lingerie set. She was unsure as to how she was going to reveal herself to Ryland with nothing on but the series of chains that wrapped around her torso, arms, and legs. She was taught how to put it on this morning when Adrian gave the set to her. She didn't hate it at all; she was so fond of how it was fashioned for her, specifically. The crystals were shaped into wisteria stems with intricately shaped flowers, colored in a gradient ranging from lilac to deep purple to pay homage to her family name. And even the faintest movement of her arm or a foot made Sei feel like she was being followed by a group of pixies as the crystals swished against each other.

Unable to overcome her appearance, Sei throws on a kimono to cover herself before she exits the bathroom. She sees Ryland sitting at the edge of the bed, illuminated by only the warm pin lights overhead. He was still busy marveling at the xenonite globe when he spoke.

"I want to bring this to the classroom when I come back to work. We'll be touching on Earth's geological characteristics soon. I'll tell them what all of these... grooves... mean," Ryland trails off as his ear picks up on the crystal tassels jingling. He turns to Sei. "What's that sound?"

Sei stops just a few feet away from him. "It's... probably the gift I got from Adrian.."

"Oh?" Ryland perks up. He smiles. "May I see it?"

"I'm... I'm wearing it."

Sei averts her eyes at the carpet as she sheds the only remaining cover she had on. Cold air engulfs her as soon as she does. She can feel Ryland staring even if she was avoiding his gaze. She takes a gamble and peers at him. Sure enough, he was ogling at her, crimson and shocked.

"A-Adrian gave you that?" Ryland stammers. He adjusts his glasses as if to get a better look.

Sei nodded. She sat beside him with her legs folded, crossing her arms in an attempt to hide her breasts. "They said that this is customary for Eridian wedding nights. I'm guessing that this is the equivalent of a lingerie set," she laughs softly as she explains the gift to Ryland. "I feel kinda weird wearing it though..."

"You're beautiful, Sei," Ryland says, quiet and reverent.

Sei can feel the red in her cheeks blooming into a deeper hue. "That's... That's good then. I didn't want to disappoint."

He put out a hand to touch her chin, and also to have her look at him directly. "I don't think you ever could, at least in my eyes."

"Th-thank you..."

Ryland beckons her to him, and pats his lap. "Come here."

Sei follows, scooting on the bed so she could perch herself on top of her husband. She puts her palms on his shoulders, but Ryland takes one of them and brings it to his lips, kissing her knuckles and the rings that were connected to five delicate xenonite chains that mimicked the tendons of a human hand, converging to a band that was fastened around her wrist. Sei also wore this on the other hand with her wedding ring. Being this exposed flustered her so much that she couldn't even speak.

"Is it working?" Sei asks with a quiet voice, chuckling softly as she recalls the rationale that this was meant to entice her partner. If she so much as looked down, she would have gotten the answer to her question.

Ryland was straining in his pants. The moment he saw Sei step out of the bathroom and disrobe herself, he had already been having trouble keeping his mind together. He doesn't even know what he was saying, telling Sei to sit in his lap. Everything was a blur except the woman before him. He was exponentially more aroused from having her so close to him like this. Ryland sighed. He needed to thank Adrian for this, immensely. His eyes could feast on the sight for the rest of his days.

"Yes," Ryland replies. "Very much."

He has now worked his way up her arm and to her neck. Sei lets out an elongated breath as he attaches his lips to the underside of her jaw, while his left hand fiddles with the metallic tassel earring. She grips at the material of his shirt. A shiver runs through her entire body when Ryland decides to maneuver all of her hair over her left shoulder, letting the light overhead reflect off the Eridian handiwork.

"I don't care as much for the sounds that these make as I do for how they look on you. I mean, it sounds lovely, but…” he whispers lovingly into the skin of her collarbone. "Thank God we evolved to have eyes..."

Sei laughed. "Eridian shade?"

Ryland shakes his head. "Not at all. Just... being grateful for biology... Evolution..." He continues kissing the expanse of skin made available to him, all while reviewing the slopes and dips of Sei's body with his hands, covered with foreign jewelry that was not helping to cool either of their physical states. Sei begins to unbutton Ryland's shirt just to level the playing field; she peels it off with relative ease as he's also letting her undress him.

Sei gasps sharply when Ryland cups her breasts. He squeezes and kneads them in his palms, rolling and tugging at her pebbled nipples every few times as he continues mouthing at her neck. He hums, pleased beyond compare.

"Pretty girl," whispers Ryland, "my pretty, pretty girl. All dressed for me..."

"I'm barely wearing anything," Sei protests, cheeks aflame from the praise. He noses at the side of her face before he kisses her, and she responds favorably: she shifts closer to him in his lap and loops her arms around his neck.

Ryland pulls back first. "You're wearing just enough for the occasion." He smiles to end his reply. His hands travel south, caressing her sides before resting on her hips where he draws her further into his body.

"Aah," Sei bit her lip a little too late. "Ry..."

As much as she wanted to press her thighs together to relieve the growing ache between them, her position granted her no method of achieving this temporary relief; if anything, this only communicated that she’s descending further and further into a much more pliant state. There’s no other way to go but down; no other way but to shamelessly grind into her husband's erection with her dripping cunt, occluded by nothing but a taunting curtain of thinner crystalline flowers.

Something about the way that the jewelry rubs against her body from the slightest movement was adding to the stimulation that Ryland was already giving her, too. The chains she wore around her body were very similar to the Eridian celebration attire, although the tassels on hers are more refined; more glittery and polished. Whoever made this was very much aware of how humans liked shiny things. Sei was torn between thanking and cursing their attention to such details.

"Can I touch you some more?" Ryland asks. Once Sei nods, he dips a hand down between them, fingers finding a comfortable position in her slick folds.

"Ry, mmh..." Sei curves away from Ryland but he tugs her back in with a gentle push on her lower back with his other hand.

"No, no, don't run, sweetheart. Come back to me," Ryland says, blandishing Sei by running his fingertips down her lower back. He pouts at her attempt to escape his touch, but he is hardly upset. He and Sei are quite similar in that area; they both pull back once the heat becomes too strong, but after spending all that time with each other on the Hail Mary, there were only a few things from which they shied away and avoided. One of these was how they pleasured each other. Sei was so much more bashful about physical intimacy than Ryland. He wasn't all too dissimilar, but her hesitance prompted him to be more forward in this aspect; kind of like a genetic disposition that gets activated under the correct circumstances.

Ryland doesn’t mind Sei's shyness. He’s chalked it up to cultural differences, yet despite this he never stopped coaxing her out of her shell. That's what he was doing with his other set of fingers right now: curling and stroking at her walls, looking for that place that he knew would yank Sei outside of her mental fortress. More noises spill out from her as he circles her clit in loose, slow shapes with his thumb.

Sei reciprocates by palming Ryland through his pants. He reacts instantly. His eyes pinch shut and his mouth hangs open, his hips bucking into Sei's touch in a conscious rhythm as he chases the irresistible pressure that the material of his Eridian textile trousers was numbing out.

Sei makes quick work in freeing Ryland from all the offensive layers of clothing. She plants her knees on either side of his thighs, whining at the loss of his fingers while she allows Ryland to slip off his remaining covering. He doesn't allow a minute to pass with his fingers not slotted inside Sei's pussy. She hums contentedly as they assume their earlier position, though with less clothes this time. No other effort was required of her other than familiarizing herself with the length of her husband's cock, hard and flushed from want; and keeping herself stable on his lap.

Sei strokes Ryland as he fingers her. They share more kisses, interspersed with breathless mundane exchanges of their current dealings and punctuated with requests for stronger stimulation: Sei's on leave from the university lab for a week. Deeper. More to the left. She's got many papers to write, but there's no need to rush. The Eridians don't need hard copies, anyway. Right there...! She plans on encoding her writing using the keyboard that Ryland uses for his students. Don't stop, Ry — oh, Ry, please, please, please...!

Ryland is more or less in the same boat. Faster, Sei. He's got lots of tests to grade, and lesson plans to review. Touch the frenulum; you know where that is, don't you? He sort of regrets introducing the concept of parent-teacher conferences to the Eridian parents, because now they want detailed reports about their children's performance, and that means less time for him and Sei on their workdays. Good girl, Sei. Keep doing that, that's it...

Neither of them could speak in English at this point. Ryland was pointedly thrusting into Sei with three fingers now that he's found where she likes it most, and Sei was focusing on the head of his cock, aware of how much this drove him crazy. Because of this, Ryland breaks first; he shamelessly ruts into his wife's fist as he comes, decorating her stomach and some areas of the chains with ropes of white. He nearly loses it again when Sei licks her hand clean. He pulls her in for a kiss — sloppy and searing — tasting his own release as his tongue melds with Sei. He prompts her to lie down so he could make her finish too.

Sei parts her thighs for Ryland as soon as her back lays flat on the mattress. Her hand greedily fists a handful of his blonde hair, and the other slips by her side so they could intertwine their fingers. He travels south, kissing her through the jewels and metals that she wore. He looks for where to remove the pieces from the waist down, and once he spots it, he's flinging the ensemble on some inconsequential part of the bed.

"Aah...!" Her hips jerk up when Ryland replaces his fingers with his mouth. He flattens his tongue over her cunt, then laps up every drop that gushes from her like it's his first time getting a taste of Sei. Sei used to be hesitant about this at first, but when Ryland assured her that there was nothing wrong with it, she no longer held herself back from grinding her pussy onto Ryland's face. She's doing it now, as a matter of fact, and Ryland is more than willing to be of use to her this way.

Sei nearly screams when Ryland couples his licking with rubbing the tip of his nose into her already kiss-swollen clit. His hands pin her hips onto the bed to keep her from thrashing. She can feel every hum and moan that Ryland makes against her pussy, and even more the way he was vocalizing the rhythm with which he was feasting on her. It was so obscene yet so delectable to hear Ryland making those sounds. Sei would have probably lost control earlier if she saw how desperately he was humping the sheets to relieve his half-hard cock.

Tears prick at Sei’s eyes as she drowns in the compounding deluge of bliss that soaks her from head to toe. The jewelry clinks and conforms willingly to her contortion as her back arches up from the force of her orgasm, rippling through her with so much intensity that she was led to assume that her soul left her mortal body for a moment.

Ryland doesn't let up. He helps her ride the wave, drinking up everything that Sei has to give him until even as she's pushing at his forehead, begging him to detach from her lest she begin a new and much more torturous ascent. He stops only when he feels it’s time to stop, and by then, Sei is a twitching mess. One of Earth and Erid's saviors, adorned to be ravished by her mate and painted in both her own cum and her husband's; shivering from the force of coming off such an exquisite high brought to her by none other than her most beloved. She was all his; and he, hers. Their arms — marked by their family crest — are the testament of that mutual belongingness.

They were only getting started. Ryland wasn't done yet, and neither was Sei.

He lifts himself up, coming to kneel before Sei as he pumps his cock back to life. It doesn't take much time; eating Sei out and seeing her come so hard were enough to goad the fire in his loins. Ryland loved Sei so much; too much. The strength of his devotion to her overwhelmed him most of the time, and it only became much more forceful as he watched her come apart from his own doing.

Ryland is leaking again when he gets himself fully erect. He dips down to caress Sei's cheek, checking in on her for a moment to see if she had come back up. Sei looks at him through her hazy vision.

"You alright, sweetheart?" Ryland asks, searching her gaze for any signs of discomfort. Sei nods. He smiles at her, ever loving and warm.

Sei mirrors his gesture. "I want more, please... I'm still... Ah..."

"Aching, hm?" Ryland can't help but smirk as he supplies the word for Sei's needs. She blushes, and nods again. She calls for him with weak but open arms.

「もっとちょうだい、旦那さん… お願いんだから…」Sei whines, her toes impatiently tracing the length of his thigh. Her pleading goes straight to Ryland's cock.

Ryland has learned Japanese along with Eridian. The main reason used to be because he didn't want to be talked shit about by Sei and Rocky onboard the ship — the former had taught their Eridian friend her own language, and oftentimes they used that advantage to talk about Ryland behind his back. In retaliation, Ryland studied Japanese to challenge their confidential conversations. This evolved to be more of an affectionate endeavor, however.

Though he wasn't too confident in speaking Japanese (Sei is very nitpicky about American accents), Ryland can understand Sei well by now, and he understands just how much she needed him to start fucking her until she couldn't think of anything else but him.

Ryland lifts her hips and slides a pillow beneath her lower back. His hands rub up and down her milky thighs as his eyes greedily take in the full view of her glistening pussy; so pretty and pink, all for him. Ryland inches closer to Sei, bringing his cock to her cunt and rubbing the head and shaft between the lips. They both groan from the feeling.

"Ry, stop teasing, please," Sei complains, reaching out to him with a hand. "I need you inside me now..."

Ryland gives in. He plants a kiss on her knee before positioning himself. He lines himself up to her entrance and slowly pushes in, anticipating that tight, wet heat that he loves so much. A moan rumbles through his chest and escapes from his lips gradually as he bottoms out; it turns into a string of whimpers as soon as he starts rolling his hips into Sei. Her tilted hips give him more access into her body, and the feeling is nothing short of heavenly.

Even the slightest push has her spasming around Ryland, as if she’s sucking him in further into her cunt. Ryland hisses as his upper body curves down. He catches himself with an arm, planting a palm on an empty spot by her head and collecting himself as fast as he can, wanting nothing more than to start fucking into her.

Sei keens once Ryland sets an even thrusting pace. He jostles her where she lies, crumpling the sheets laid out beneath her and mussing up her hair further against the pillows. Every downward force of his hips makes the metal tassels sway. Out of instinct, her legs lock him in, effectively pushing him deeper. Ryland curses without censoring himself for the first time in years.

"Fuck," he gasps, "Sei, t-that's… God, sweetheart, mmh — take me in deep, that's it, that's a good girl..."

His eyes pinch shut, then flit open again from the overwhelming warmth that Sei had him wrapped up in. A hand reaches up to cup her cheek. Ryland coos when Sei leans into his touch, prompting him to adjust himself. He stops for a moment only to get further into her. He hooks both her feet onto his shoulders and starts pounding into her.

"Ry —!" Sei scrabbles to grab at Ryland. She paws at him ineffectively, her strength faltering from the bolts of pleasure that were coursing through her body. "Aah, mmgh!"

"Yeah, baby?" Ryland pants along with the rhythm of his hips. He leans forward and slows down to a sensual grind, which only drives Sei crazy. The way his pelvis was rubbing so deliciously against her clit was making her head spin. Ryland smiles down at her lopsidedly. "B-be good and - ah! - tell me what you want."

"I-" Sei breaks out into a blissful sob. Ryland slows down to let her speak and wipes away her tears. "Nngh, agh...! P-please - please kiss me..."

Ryland bends towards her, capturing her lips and slipping his tongue back into her mouth. He resumes his earlier speed. Sei whines into the kiss as her fingers weave through his soft, messy, blonde tufts. Her tugging only spurs Ryland on. He parts from her and directs his attention to her neck, nipping at the flushed pillar of skin.

He pauses for a moment; he wraps his arms around Sei's midriff and lifts her up, eliciting a small noise of surprise from her. Her cheeks flare up from the new position. He kicks away the pillow beneath her earlier.

Sei was on his lap again, much like how she was before when she first got drunk on the ship and told Ryland about everything: her clan's mistreatment of her during her childhood, her reason for moving to the States, and why she volunteered. She told herself then that she'd never let it happen again, to never act so improper in front of a co-worker after that, but by that time she knew deep down that she had stopped seeing Ryland as just a crewmate.

"R-Ry, what..." Sei trails off, her hands awkwardly resting on Ryland's chest. He takes one of her hands and kisses her palm before weaving his fingers through the gaps of hers, leaning back on the headrest. He smiles at her, glassy-eyed behind his glasses from adoration.

"I want you closer like this," Ryland says. "I'll lead and you follow, hm?" He takes hold of her waist as he cants his hips upwards once to test the waters, to see if Sei was comfortable. All he needed was to hear her moan before continuing, armed with the knowledge that he was doing exactly what Sei wanted.

The tassels jingle as Ryland thrusts up into her, and it's all music to their ears when Sei grinds back down onto him. Her jaw goes slack at how deep Ryland can now reach inside her in this position. If she shifts slightly to the—

"A-ah!" Sei half sobs and mewls when Ryland hits that spongy patch of nerves. Her fingers inject into the muscles of his back from the electrifying surge that runs through her back, trembling with both the force and the tingling sensation of being stimulated so strongly.

Ryland stops and stares up at Sei. He kisses away the tears that run down her cheek. "Right here, baby?" he thrusts up to her at the same spot and Sei cries out again.

"N-no, agh - ! Please, not there, Ry... Ngh! Nnh, mmgh...!" whines Sei as he resumes his movements. Ryland is now fully focused on getting her to cum again, and it's pulling her out of her rational mind real fast. She colors when he smiles up at her, all breathless and just as fucked out as her. It was all too much for him: the feeling of Sei's slick, velvety walls gripping him so tight, her voice crying out for him in a sloppy dialectics of wanting him to stop but also to continue fucking her senseless.

Sei comes for the second time that night, and before she could even recover, Ryland manhandles her one last time, laying her on her back again as he folds her legs up and over her torso. The gems of her anklets shake and clink near his ears as he pummels into Sei.

"Ry...! Augh...! I just -" she sobs, "I just c-came, please..."

"Please what, Sei...?" Ryland turns to kiss her ankle. The palpable heat between them is making his glasses fog up and obstruct his line of sight, but such a trifle doesn't convince him to stop. "Use - use your words, come on... hm? What is it?"

Sei tips her head back on the pillow, eyes bleary from her tears. Ryland sees this and only fucks her harder; the knot in his stomach growing more and more taut at each passing second.

「中に出して…！」 Sei manages to reply before she wails again, announcing another impending climax.

Her words were enough to make Ryland snap. His hips stutter and he comes, crying out as he spills every drop of his cum into Sei; he doesn't stop moving until Sei finishes as well, ignoring the burn of overstimulation until all he could hear was the voice of his wife babbling his name as she descends from the high they've brought themselves to.

Sei lays limp on the bed, her legs giving out from exhaustion while Ryland collapses atop of her, equally out of breath. He breathes out a laugh when Sei lazily puts her arms around him, and he returns the gesture, chuckling as he rolls them over so that she’s more comfortable.

Ryland could've pulled out in this moment, but he elects not to, wanting to stay inside Sei for as long as she'll allow. He's happily rubbing noses with her because she doesn't seem like she'd start telling him off for being clingy. His free hand reaches for hers, the one where she's wearing the xenonite ring that they exchanged earlier this morning.

"I used to think it'd never happen," Sei murmurs. She was also looking at the ring.

"What, getting married to an American?" Ryland jokes. He adjusts himself so he could have a better view of her face.

She shakes her head. "Going to space." She snorts and then laughs, nuzzling into his neck. "Yeah, getting married to an American. My grandmother would've gone ballistic," she says, "but I know that she would've warmed up to you. She won't disapprove once she knows that you make me happy." Sei presses a kiss onto his chest. "You're one of the few who understand me well."

"I am?"

"Mm."

"Oh."

"Take the compliment, Ry, please."

"Alright, alright — compliment taken," he chuckles. "It all just feels surreal to me."

"The compliment?"

"Having you here. Being here, on Erid, with you."

Sei smiles. "I'm still stuck on the fact that Adrian gifted me lingerie for our wedding night."

"Won't be the last time that you'll wear it," Ryland says. This earns him a soft smack on the shoulder. He breaks out into a laugh, opting to apologize for teasing Sei by kissing her wherever he could reach.

She pulls Ryland down with her again; a sign of forgiveness that she so readily offers him, time and time again. He gathers her into his arms, kissing her forehead as they settle back onto the pillows.
