For Science ~ ryland grace x reader
based on my post from last night about rocky and Adrian wanting to watch purely for science and ryland being kinda too into it. "4 scientists standing in a circle consenting to let each other watch" to quote myself lmao
3k words, smut, voyeurism, exhibitionism, all consenting adults
-----------------
Itβs not like the topic of sex hadnβt come up in the years you spent traveling with Rocky to Erid - he was curious by nature, fascinated by the human body and all its inner workings - but he respected the fact that it was meant to be a private act. He would pretend he never heard you and Ryland when things got a little steamy, making himself busy on the far end of the ship until the sounds quieted down.Β
So now, sitting on the beach with Ryland, Rocky and Adrian, you were stunned into silence by the blunt questions being directed to you. βYou want to what?β Ryland gapes beside you. βRocky, Adrian want to observe human mating,β said so easily in his melodic tones. Ryland looks at you for help, not sure how to continue this conversation.Β
βFor science!β Adrian chimes in, βyou are first humans weβve known, we want to study everything.β
βYou watch Rocky eat, this seems like fair trade,β Rocky states, tapping a claw against the sand. You choke out a laugh, willing the heat in your cheeks to dissipate. βSorry,β you start, glancing at Ryland to see the pink dusting his cheeks, βyou want to watch usβ¦ have sex?β
βYes, observe sex,β Adrian settles a little further down, tilting their carapace toward Rocky. βI know is private ritual,β he hums, βbut could be good data to have.β
Ryland nods slowly, staring at his knees while he thinks. Finally, he sighs and faces you, βwe would ask the same thing if we were in their position.β He purses his lips, biting back a grin at the shocked look you shoot him. βYouβre thinking about it?β You ask, disbelief coating your words.Β
He laughs, throwing himself back to lay in the sand. βIβm just saying I donβt think itβs such a crazy thing to ask.β He gestures to the aliens next to him, βlike, theyβre hundreds of years old, theyβre intelligent beings, theyβve got a brand new species of equally intelligent life living in a terrarium on their planet, surely theyβd want to know.β He lifts his head just enough to look at you, trying to gauge your reaction to his thoughts.Β
Before you can form a response, Rocky stands proudly. βRocky already heard all noises on ship, human mating very loud.β
You groan, kicking Rylandβs leg when he lets out a belly laugh at that. βCanβt you just like, watch porn on your laptop?β Youβre grasping at straws at this point. βNo,β Rocky says immediately, βGrace said porn isnβt realistic. Rocky want to see real thing.β Ryland laughs again, covering his face with his hands, βI did say that.β He peeks at you over his fingers, snorting when you roll your eyes and flop into the sand beside him.Β
βHey,β he turns his head to you, βonly if youβre comfortable with it.β You think for a moment, trying to find a reason to deny the advancement of science other than sheer embarrassment. βIt does feel a little like weβre zoo animals,β you sigh.
βWe are zoo animals,β he whispers, hand finding yours, βbut we have a choice.β His thumb strokes over your knuckles, βbesides, they could learn so much about our biology, think of the studies theyβll be able to do with a few samples from us.βΒ
βSamples?!β Your eyes go wide, βyouβre already thinking about jerking off in a cup for them?β He turns away with a cackle, βtheyβre already studying our bodies,β a quick point to a bruise on his arm from the most recent blood draw, βwhy wouldnβt they want to learn about reproduction? They already know how it works, we tag-teamed so many of those conversations on Mary.β
You groan, squeezing your eyes shut like you can make the conversation end if you canβt see any of them. βCome on,β Ryland whispers against your cheek, βletβs be guinea pigs.β The grin he cracks is thrilling, like heβs finally living out a fantasy he didnβt know he had. βYouβre a fucking nerd,β you breathe quietly, smiling when he buries his face in your neck. βIs that a yes?βΒ
βYes, fine, we can do it,β you mumble, laughing when he throws a fist in the air and turns to Rocky and Adrian, still sitting quietly beside him. βOkay, weβre in,β heβs all business suddenly, βhow do you want this to work?βΒ
βJust want to watch, we go now?β Rocky stands and starts heading in the direction of your little house. βWha - now, now?β You stammer out, eyes flying to Ryland when he stands and offers a hand to help you up. βYes, now,β Adrian answers, launching into a list of positions they researched and ranking which ones they wanted to see the most.Β
β-------
The house is quiet, late afternoon light filling the space with a nice glow. You stand nervously in the bedroom, watching as Rocky and Adrian make themselves comfortable on a bench Ryland dragged in. You set your boundaries on the walk back: the Eridians wouldnβt talk, if either of you were uncomfortable at any point youβd stop, Ryland wasnβt allowed to teach while actively fucking you. All the normal stuff.
He sidles up to you slowly, hands coming to rest on your waist. βReally? A cuck bench?β You laugh, gesturing to the other side of the room. He laughs too, winking while he draws closer, βa scientific, observational cuck bench.β He stops before he kisses you, βjust focus on me,β he breathes against your lips, feeling your body release a little tension at his proximity.Β
You melt into him when he finally presses his lips to yours, trying to push your nerves to the back of your mind. Ryland takes his time, kisses you slowly, passionately, like heβs trying to draw out every insecurity from your body, like he wants you to enjoy it with him. Gentle fingers slide under your shirt, spreading over the warm expanse of your back. He pulls you against him tighter, groaning quietly when you roll your hips against his.Β
βThatβs it, baby,β he whispers in your ear, teeth nipping the sensitive skin below it. You tilt your head to give him more access, breath hitching at the way he sucks marks on your neck. You can already feel his erection against you, pressing insistently as he sinks his hands under the waistband of your pants, fingers squeezing the plush flesh of your ass. You palm him through his sweatpants, feeling him shiver against you when you get the pressure just right.Β
He chokes on a whine, pulling away from your neck just long enough to get his shirt off. Your hands trace over the expanse of his stomach, you canβt help but admire the extra weight heβs put on. He grins against your lips, big hands cupping your face before heβs moving to pull your shirt off too.Β
The cool air against your skin suddenly reminds you that youβre not alone. Ryland feels the tension return to your frame, shifting so your back is to the aliens in the corner. He strokes your arms and kisses you soundly, his tongue claiming yours in an attempt to keep you in the moment with him.Β
βSo fuckinβ pretty,β he murmurs under his breath, feeling the goosebumps that raise under his fingers. βCold, sweetheart?β His smile makes your heart skip again, he looks at you like you hung the moon. You nod and he twists his mouth like heβs thinking of the best way to warm you up. βWant me to help?β Heβs teasing now, clearly getting a thrill out of making you grin despite yourself.Β
βLay down for me,β he kisses you again for good measure. You climb on the bed, laying against the pillows while he sheds his pants with a wink. βLove you,β he whispers into your skin as he works his way up your body. You arch enough to let him unhook your bra, accepting the deep kisses he gives you when he throws it to the ground.Β
A soft moan makes its way out of your throat when he licks down your neck and chest, slowly working his way to your breasts. He looks up at you from under his lashes when he takes a nipple in his mouth, eyelids fluttering when you stroke a hand through his hair. He sucks on your breasts like itβs his job, drawing out sounds from you that are almost embarrassing in current company.Β
When you tug his hair with a murmur of his name, he groans, tongue vibrating against your sensitive nub and pulling a whimper from you. He pulls off with a pop, a string of saliva connecting his lips to your nipple. The sight sends a shock to your core, your hips rolling against him and head tilting back. He smirks to himself, shifting so he can get your pants and underwear off.Β
He sits back on his knees and takes you in. Soft hands lift your leg, his lips leaving sweet kisses from your ankle to your knee. He lays flat, dark eyes locked on your pussy, not even trying to hide the growl that claws its way out of him. Seconds tick by with no additional contact, you reach for him, tugging his hair again.Β
βPlease, Ry,β you whisper, moaning when he licks a stripe up your core like thatβs all he was waiting for. The first taste has him groaning against you, his eyes rolling back and fingers flexing on your thighs. βSβ good,β he whines into you, pressing your legs further apart.
You throw your head back, grinding your hips when he bumps your clit with his nose. Itβs a little exhilarating knowing that youβre being watched in such a vulnerable position. Ryland between your legs, slowly taking you apart with his tongue, encouraging you to take what you need. And it doesnβt help that Ryland seems to be working twice as hard as normal, like heβs trying to show off to aliens who donβt know any different.
You feel a hand leave your leg and soft fingers prod your entrance. He looks up at you without breaking his rhythm, waiting for permission that you give quickly, willingly. You feel more than see the smile that pulls at his lips, then he pushes in and squeezes his eyes shut. βOh, baby,β he groans into your skin, βso tight, so warm. This all for me?β Your breath hitches, you love his mouth in these moments.Β
βJust for you, Ryland,β you moan, back arching when he slides a second finger in. He growls again, speeding up his movements and chasing your release like it already belongs to him. A curl of his fingers has you bucking into his hand, spreading your slick against his chin and cheek. You clench down, guiding his head to exactly where you need him to tighten the coil in your stomach.Β
He flicks his tongue and sucks just right, staring up at you with wide eyes as he feels you building. Little groans of, βmhm, mhm,β fall from his lips, spurring you towards the edge. A gasp pulls from your throat and your whole body tenses, heat rolling through you in waves. You grind against his face, feel him lick up your release as it spills around his fingers still nudging that spot inside you.Β
You flop down in the bed, breath coming in harsh pants, and take a second to assess your body. Your legs were tingling, vision a little fuzzy, core spasming as Ryland slowly pulls out. He stays where he is, pressing kisses to your thighs and hips, whispering praise until he sees your face relax fully. When you reach for him, he moves quickly.Β
He wipes his mouth with the back of his hand, smiling when you let out a small sound. βDoing okay?β He asks against your jaw, fingers intertwining with yours and lifting above your head. βYeah,β you breathe, βI could go for another one.β Itβs your turn to wink at him.
βI can get back down there if you want,β he teases, licking into your mouth when you laugh. βMm, Ry, I wanna come with you,β you hold his face with your free hand, thumb swiping against his cheek gently. That sweet pink shows itself on his skin again, making you giggle as he drops his weight into you.Β
βI think we can make that happen,β he groans, shoving his boxers off with one hand and kneeing your legs farther apart. You spread easily, so wrapped up in the man above you that you forget thereβs been an audience here the whole time.Β
He wastes no time, slotting his tip against your entrance with a whimper against your shoulder. You roll your hips just right, feeling him slip in. He shudders above you, βsl-slow baby,β he begs, βyβ got me so worked up.β A sharp nip lands on your neck, causing your head to drop back again with a moan.
βLove those noises you make, so sexy,β heβs talking to distract from the fact that heβs not moving. βCan feel you squeezing me already, god, youβre amazing,β he slides in another inch, gasping and groaning when he feels your walls give way for him. βOh- oh baby, fuck.β
You try to relax, try to make it easier for him, but the sounds falling from him are so hot, you canβt help the occasional clench that rocks you both. It takes him a while to push all the way in, he does everything he can to keep it together when he bottoms out and you gasp right in his ear. Heβs not usually so sensitive, you briefly wonder if being watched is doing it for him that much. He did agree to it pretty quickly, after all.Β
He gives a testing thrust, panting above you with the effort. You roll your hips when he finds a rhythm, feeling how he squeezes your hand still in his above your head. He builds speed, practically fucking you into the mattress with the depth of each thrust. Youβre a mess beneath him, moaning and gasping, head tossing and turning, free hand sinking nails into his back and neck.Β
A steady string of βyes, yes, yes,β punches out of him, like he couldnβt keep the words in if he tried. Without breaking his pace, his big hand grabs the back of your thigh, heaving it up towards your chest. The new angle makes your eyes roll back, his cock reaching deeper and deeper. A growl rips from his throat, low tones vibrating against your chest. You hug him to you tighter, taking everything he gave you with barely concealed elation.Β
He feels you clench around him particularly hard, feels how close youβre getting. He releases your hand to grab your other leg, pushing it up to match the other one. The position pushes the air out of your lungs, your legs shaking under his hold. βGive it to me, sweet girl,β he rumbles, βcome on my cock, baby.β
You slip a hand down to where youβre connected, gathering some slick and rubbing your clit in rough circles. Your fingers brushing against his length almost makes him cum, he whimpers into the air and grits hit teeth to stave it off.Β
The sensations build, your body going taut as you finally crest the wave. A broken cry rips from your throat, legs shaking against his strong hold. It shatters through your whole body, heat and sparks for what feels like an eternity before you can suck in a breath. You clamp down on him and it tips him right over, a loud groan signalling his end before you feel warmth flood your walls.Β
He fucks you through it, dropping your legs in favor of leaning forward and kissing you messily. It's all teeth and tongue, heβs practically drooling into your open mouth. Your body relaxes against the sheets again, letting him press you into the mattress with grounding weight. He places sloppy kisses all over your face and neck, eyes half lidded in his own daze.Β
βJesus, okay,β he laughs with his face hidden, βI was really into that.β A surprised laugh bubbles out of you, your hands cupping his cheeks to lift him up where you can see him. βI could tell,β you smile at his blush, βitβs been a while since you went for a mating press.β He grins into your palm, βAdrian mentioned it and I couldnβt stop thinking about it,β he sighs, pressing a sweet kiss to the tip of your thumb.
He rubs your side soothingly, turning his head to Rocky and Adrian, βyou guys, uh - you got what you needed?β You look over to see them stand, stepping off the bench like normal. βRocky has questions, statement.βΒ
You and Ryland burst into giggles, βyeah, of course. Just give us a few minutes to clean up?β They amble towards the door, βRocky, Adrian wait on beach, have much to discuss.β
You donβt have a chance to ask what that means before theyβre gone. Ryland turns back to you slowly, βI know they donβt have anything to compare that to, but is it weird I wanted to impress them?β He looks shy, like he canβt believe that just happened. βTheyβre actually talking right now about how much of a beast Grace is in bed,β you laugh, squeezing his cheeks when he goes bright red.Β
He groans and rolls off of you, covering his face with a pillow. βYouβre never gonna let me live this down,β it comes out muffled but you hear it anyway. You shift to lay against his side, βhey, I was as much of an eager participant as you were.β
βBesides,β you skim your fingers over his chest, βit was kinda hot, seeing you so lost in it.β
βLost in it?β He snorts, pulling the pillow away. βMhm,β you hum, βlike you were drunk on me.β He grips you tightly with both hands, sliding you up his body until he can kiss you properly.Β
βWe should ask them to make alcohol so we can do that again tipsy,β he whispers against your lips, smiling when you push his head away with a laugh. βAdrianβs got more positions they want to see, anyway.β

ryland would SO be down for the science and accidentally discover new things about himself, like he's just always down to experiment lmao
