a/n: i guess the pearls forming are kind of like whatever various stones the human body makes but not so gross, dont think too hard about how it works just enjoy the crazy mermaid smut <3
Working at the hybrid aquarium and rehabilitation center was the best choice you had made within the past five years. You had been volunteering when you were offered a job. You took it of course! It was a fun and fulfilling job! You got hands on experience with so many different animals and hybrids. Helping them go on to live better lives if and when possible. Some prefer to stay at the facility, happy enough in containment not having to fight or work for food.
Sometimes though, you couldn't help but feel some of your tasks were above your pay grade. You were happy to lead the guided tours around, introducing people to resident mers and hybrids, letting people pet and interact with the stingrays. You don't mind having to give medicine to the sick mers, you don't even mind cleaning out and prepping the quarantine tanks.
But just sometimes you weren't sure what you were doing at this job. Some things you felt so unqualified for.
Like today. While you had some experience caring for the animals and hybrids medically, most of that was just being handed a dose of medicine and told to give it to one of them. You were kind of unprepared to accompany one to the doctor, as it were. Even though you were pretty close with Joost, the mer in question, you weren't supposed to make friends with any of the hybrids especially those set to be released eventually. But you couldn't help it, Joost was such a friendly critter.
Joost had come to the center after getting attacked and needing a few stitches on his abdomen, he was mostly good now, the stitches had come out and he seemed in good spirits. Usually. Apparently he had been acting lethargic and complaining about pain and kept getting brushed off as a tummy ache.
So, you were there to keep him company and make sure he didn't freak out at being examined. He flopped over the edge of his pool, pouting because he was pulled up from the bottom for the check up. He had little interest in talking so you let him be and wait for the doctor.
They come in hauling a cart behind them, and starts tending to Joost after a few pleasantries are exchanged. The doctor easily checks all his vitals and finds them good, except for a slight high temperature. They ask him to go belly up so they can investigate him, he whines and grabs your hand when the doctor starts palpating his abdomen, moving lower and lower as he indicates. The doctor discusses his symptoms and what has truly been going on with him recently. They speak softly into a walkie talkie, before excusing themself for a moment.
Joost wiggles and pulls himself out of the water while they're gone, hauling himself onto your lap without second thought. He whines about wanting to go back to his little area. The doctor sighs a little when they return and the mer is wrapped around you, you've got your legs in the water, you having ditched your shoes and socks and rolled up your pants to do so.
The doctor returns with another employee who holds a plastic case in one hand and a small bottle about half full of something blue. The two of them talk together quietly setting up the device and you stay sitting there with Joost, who's still all up in your lap, lower half twisting uncomfortably in the water. The doctor requests Joost at the edge again, introducing their partner as a tech, the person who can interpret the scans.
The device is explained as a portable ultrasound machine, the tech talks him through the procedure, touching it to his skin and showing what it will feel like to make sure he's okay with it before proceeding. You end up basically on your belly, holding his tail up while the doctor moves the gel coated probe over his abdomen, the tech watching the ultrasound itself.
He whines and covers his face, embarrassed surely, you think. He's being felt and examined by so many people, it must be embarrassing. Especially when the tech describes what they're seeing. Apparently the stress of the injury and coming to the center was so great that Joost's body started creating pearls, they explain the science of it but you kind of just tune it out on accident.
The gist of it being the pearls are what is causing him pain and discomfort and have to be extracted. He shakes his head and yelps at the prospect of surgery, to which the doctor kind of shrugs and says he has to get them out somehow. Explaining the easiest way besides surgery would be sexual arousal, orgasm would force the pearls out of his body. They offer maybe he can take care of it himself, or another medical professional will. He mumbles that he'll figure it out and the tech and the doctor and tech both pack up and leave.
You're pulling on your shoes when he speaks again. "Can you help?" Joost asks gently, peering up at you, one hand grabbing the edge, the other rubbing and soothing the pain.
"You sure?" You ask, uncertain. You weren't supposed to get close, weren't supposed to let them bond with you. But you were far beyond that at this point.
He trills a little and nods. "Mh, please? I don't want the doctors to do it, it would be all..Clean, weird." Sterile, he means. His brows furrow and pinch together in the cutest way.
You just can't say no to that face.. "Okay, I'll see if I can come in early tomorrow."
"Thank you," He grins, webbed fingers grasping at the air, beckoning you close. He grabs your face and plants a kiss on your lips when you do. "Thank you, thank you."
The next morning, you arrive early, before the center opens to the public. Joost is already up and on the sun shelf when you get there. "Hi, hi, hallo!" He chirps, giving a crooked grin.
"Hi, Joost, how are you feeling?" You ask gently, kneeling at the side.
"It still hurts, but you'll help, ja? Help me?" He grasps your hand in both of his, giving the back of your hand a couple kisses.
"That's why I'm here. How do you wanna start?" You feel almost awkward, but he knows you better than the doctors.
"Need you to touch me, please. Please.." He rolls over, hands stroking down his own body.
You watch him pause, fingers pressing into a slit in the scales. "Here, please.." You can't help the sharp inhale as he uses two fingers to spread open the slit, catching a glimpse of the pink of his walls.
It's so erotic, this sweet mermaid begging for your touch because he hurts so bad, holding himself open, begging for your touch. "Fuck. Yeah, okay." You nod, thinking how you can get closer. You decide to go get your wetsuit, promising you'll be right back.
A coworker spots you at your locker, asking what's up, and you say simply you have to help in one of the tanks. It's not a lie. They nod and let you go to change.
Joost trills when he sees you coming. "Look so nice," His tail wiggles in excitement. "You'll come in with me?"
You laugh softly, eyeing him up and down, spotting how his slit looks puffier now, his fingers playing along the line of it. "Yes, I'm coming in. Silly…" You ease yourself into the water, it's pleasantly warm. The mer comes right up to you, purring as he touches you.
"Missed you.." He murmurs, grasping your face and bumping his forehead against yours.
Maybe you had gotten a little too close and visited Joost in his recovery pool a little too often…
"I missed you too," You sigh with a smile when he smooches your cheek. "How do you wanna do this?"
You hadn't gone this far in your relationship with the mer, maybe that was part of why he was stressed out.
Joost hums in thought, before wiggling around, pressing his back to your chest, sitting between your legs. He takes your hand and guides it to his slit. "Please.." Is all he says, giving a whimper when your fingers dip inside.
You watch what you're doing over his shoulder, going between rubbing the swollen skin and dipping just inside. Mostly just mapping him out, you can see pink flesh showing from how aroused he is, hot and dripping wet too. You sigh as your fingers slip inside easily, and feel something else just inside, at the top of his slit. He whimpers and trills as you tease him, fingers petting deeper, investigating.
"Oh," You gasp softly, feeling something pressing at your fingers, and he gives a little please. "Oh my god.." Your fingers are swiftly pushed out by his cocks, two big soft cocks that flop on his tummy as they slide out.
You take them in your hands, feeling how thick and heavy they are. "Look at this, you keep all of this tucked away inside, huh? Never would've known.." You murmur, pumping them in your fists.
Joost trills and tosses his head back against your shoulder, his cocks pulsing in your grasp, the tips, soft and flexible, twist and squirm as your hands move down. It doesn't take long before both tips are squirting cum, and he's crying out, one of his hands desperately feeling inside himself. After a moment and a lot of loud desperate whining he's pulling out a small pearl.
"Here.." Joost says, pushing it into your hand, making you let go of his dicks.
"Oh, wow. How many did they say you have in there?" You ask, examining the pearl, not a perfect sphere, slightly oval shaped. You set it carefully on the edge of the pool.
He groans when your hands return to his slit. "Mf… Fuck, I can't remember… Ten, I think."
"Okay, that's okay. We can do that, huh?" You slide your fingers in him, drawing this trilling whine out of him. He's so hot inside, his walls soft and squishy under your fingertips.
One hand focuses on gently fucking his slight while you jerk off one of his cocks with the other hand, he squirms between your legs. "You can't get overstimulated already, Joost. We just started, got nine pearls to get outta you." You shush his whimpering as he's overcome by another orgasm as you're thumbing at the tip of his dick. You work another pearl out, setting it aside before returning to business.
His tail thrashes as you continuing fingerfucking him, cramming three fingers in his soft, swollen slit, pumping them in and out. "Doing so good, oh there we are, good job," You purr, getting out two more. "Look at that.."
"I need a break, fuck…Please, please..." Joost pants, pulling at your hand.
"Come on.. We're almost halfway." You don't pull out but stroke his spasming walls gently.
"It's too much," He whines, he can't help the way his body pulls your fingers in deeper. "It's so good, oh fuck!" Chirps spill from him, these sweet noises, simply unable to hide how much he needs this.
The pearl slips out of him when he does get your fingers out. You give him a moment to breath, looking at the slick and cum that coats your hand. You indulge yourself and stick your fingers in your mouth, groaning at the taste of him, salty, like the seawater he lives in.
After about a minute, you return your hands to his needy body. "You ready?" You ask gently, getting a trilled out yes. He gasps sharply when your fingers slip back in, so easy like he's meant to be stuffed full.
You start slow again, two gently in and out of him, your other hand joining his around his cocks. Both of you working to get him off and get the pearls out. "So good, baby, you're doing so good." You get a sweet trill out of him with that, and another pearl.
You pick up your pace, jerking his cock and thrusting both fingers in and out, curling them here and there.
His muscles tense and his tail twists with his next orgasm, openly whimpering your name. He gushes around your fingers, unable to control it, two more pearls rush out of him as well. "Oh, good job..Only two left…" You put them aside and pull your hand out to focus on his cocks once more, since his hand fell away.
You jerk both of them off, watching the way he reaches down and parts his slit with both hands. He's whining and trilling, watching himself as well, watching the way his hole clenches around nothing. "So pretty…Fuck, I shouldn't be saying that but you are.."
He chirps your name, sweet and pathetic, as he cums. Right in front of your eyes, the last pearls pop out one by one out of him, as he's still holding himself open. His hands fall away after that, as he pants and whines from the sheer feeling. You let go of his cocks and grab the final pearls to set on the edge, returning your hand to stroke his slit, cooing praise into his ear. You take some of the water and splash it on him, making him gasp at the feeling, the warm water feeling almost cool against his hot wet slit.
"You did so good, oh my god. That was incredible." You rinse your hands in the water, though you yearn to lick the salty, fresh cum from your fingers. You let him come down from the overstimulation.
"Thank you," Joost wiggles and twists to face you, pulling you a little deeper into the water to hug and kiss you. "Thank you so much!" His eyes are half lidded and his cheeks are flushed and he's still so obviously aroused. But you know you can't do anything more now. Not right now. You feel so lucky having not been caught fingerfucking the mermaid stupid.
"You're welcome, baby," You shouldn't be calling him that, but it's kind of whatever at this point. "I have to get to work now, okay? I'll be back later."
He pouts but nods, kissing you again, and once on your cheek for good measure. "I'm keeping these." He giggles, scooping up the pearls.
"Yes, it's only fair. You made them after all." You laugh as well as you get out of the pool.
"I'll make them into something for you when I get out of here, ja? How's that sound?" Yeah, he's bonded hard, and you have too.
"That'd be so sweet. I gotta go now, bye." You return the kisses he blows and scamper from the room hearing an employee with a cart, coming with breakfast for the mer.
They ask what's up and you say you had to help out, they laugh at that and remark on how much you do, and how you should be paid more. You agree, you should be paid more for all you do.
𖤓 early in the relationship, you both try to hide it from his fans/public eye, but it eventually becomes obvious that you two are dating. it brings you two even closer and joost is happy to finally show you off on tour and on his socials<3
𖤓 a lot of his fans support your relationship after seeing you sweet and genuine you two are. at first there is some backlash due to jealousy, but most fans think you're beautiful and kind and want to see more of you and your relationship with him.

⸝⸝ ‘you should wear these more often’ — joost klein
content warnings | MDNI ! nsfw , gn!softdom!reader , sub!joost , dry humping , teasing , joost is a bit pathetic here , but that’s how i like him , it’s a bit short…
the pink sits so prettily against his skin. joost is perched on the couch edge, knees pressed together, eyes fixed on the floor. his cute pink boxers the soft, silky ones you bought him, are stretched tight over his hard-on.
you’ve been grinding against him for an hour. now you’ve got him desperate , pants off, just in the pink.
“look at you,” you murmur, stepping between his knees. your voice is soft, warm. “all dressed up for me. so pretty. so worked up.”
“they’re not—” he starts, but you shush him with a finger on his lips.
“they’re pink. they’re soft. and they’re the only thing between us. isn’t that right? just this softness between your cock and me.”
he nods, frantic. you can see the damp patch already forming at his tip.
you pull him forward, pressing yourself against the front of his boxers. the friction is immediate. he gasps, hips stuttering against you.
“that’s it,” you whisper, breath ghosting his ear. “rub against my jeans, baby.
you grind slow and deliberate. rough denim against the soft cotton. you feel his heat, his pulse, through the layers. each roll smears his pre-cum into the garment.
“joost,” you breathe. “i can feel you leaking. your pretty boxers are getting so wet. so messy. all for me.”
“please,” he whimpers, eyes squeezed shut, hands gripping your forearms. “please, schat, i need—”
“you need what, sweetheart?”
“i need to cum. s’fucking bad. please, let me cum. i’m so close, i’m gonna—”
“gonna what? gonna make a mess? gonna soak your cute pink boxers for me?” you grind faster, harder. his cock jumps against you as he lets out the most pathetic moans you’ve heard from him. the cotton now thoroughly soaked, cool and slick.
“cum for me,” you groan. “cum in them. let me feel it.”
he sobs, a broken, whiny sound, and then he’s pulsing. you feel the hot, wet rush through the fabric, the cotton growing impossibly heavy. his hips jerk erratically against you as he comes, head falling back, silent on his lips.
you keep grinding through it, milking every spasm, feeling the flood soak through to your jeans. the air fills with his salty, musky scent.
when he stills, boneless and panting, you pull back just enough to look. the pink is darkened, plastered to his skin, a glistening mess. white streaks leak down his thigh.
you smile, reaching down to brush the soaked cotton. he flinches.
“look at that,” you say, voice soft with awe. “you made such a pretty mess. so good f’me.” eyes on his dazed face, you kiss his forehead. “you should wear these more often”
a/n: ahhh i had sm sm sm fun writing this!!!! tysm oomfie for this request and your very sweet words!! i agree,,, i also love joost and his pink boxers.. they have been on my mind for quite some time hehehe
I wish I was a tattoo artist to get an opportunity to touch him 😵💫
I knowww!! His tattoo artists are soo lucky 🤭
It’s a good cliche for a reason, imagine tattoo artist reader getting to touch him as they tattoo him, one hand pressed to his skin as other other works, wiping his skin clean, even just diligently shaving him for the tattoo 🤭🤭
