Sasuke swam to the edge of his tank and rested his arms on the edge, resting his chin on his crossed forearms, staring at his caretaker through the open separations of his shelter and the next one over. She always wore simple clothes overtop of her swimsuit which consisted of a skirt and a translucent long-sleeved crop top. She cycled through swimsuits, sometimes wearing one that showed off her midriff. Sometimes one that covered everything up to a high neck. Occasionally she would wear one that dipped deliciously low into her cleavage. Then, on special days she’d even wear a 2 piece.

Today she wore a new one. It was a new two-piece with a simple high hip bikini bottom. It had a tie-back wrap cross-style top with two straps that crisscrossed over her ribs and tied together in the back that showed off the centre underside of her breasts. As she bent down to grab the bucket of food for his neighbors, the Aquatic Water Serpents, he saw how tightly her swimsuit clung to her body.

More specifically, he saw how tightly it clung to her cunt and ass as her skirt lifted up enough it was entirely on display. He bit his lip at the sight and he felt his cock stirring in its sheath. He waited patiently, though. He’s her last stop for the day so he always gets to spend the most time with her.

He could wait. She was on her second to last stop anyhow. She scritched under the serpent’s chin and smiled at the youngling before heading off.

“Be good for Iruka, little one!” She cheerfully called back to all the hatchlings and closed the separation before heading to the one that led to the last Silvertip Shark Mer. The rest of his kind had been either poached or fallen victim to his elder brother who had been sent into a cannibalistic frenzy before he regained his sanity long enough to see what he had done and sacrificed himself to the poachers who stayed circling their cove.

The Search and Rescue facility he was currently residing in, Konoha, had found him as a pup and had taken him in. Apparently, they searched for another of his species, hoping to find a female, but couldn’t find even a sign of them. He didn’t mind, not in the slightest. So long as he could appreciate the beauty of his caretaker day after day, he was certainly happy. Of course, he would love to do more than just look at her, but he could wait. Luckily, though, it seemed he didn’t have to wait much longer from the conversation he’d overheard the night before.

The Research team that was tasked with replenishing extant species, particularly ones that they could not find viable mates, like Sasuke, had seemingly made a discovery.

‘We found something groundbreaking, Ma’am! It means that we can replenish the Silvertip Mers’ Species without needing a female Silvertip.’

‘Well, what are you waiting for, Shizune?! What did you find?’

‘It seems because Mers share nearly 50% of their DNA with humans, they can breed with Humans. Though that means it’s about a 50/50 chance if the offspring comes out as a Human or a Mer, though it seems it would be like any other Parent-to-Child Genetic Trait, one child could come out as Human but the next could be a Mer, it just depends on which DNA prevails.’

‘That’s perfect, Shizune. Now we just need to find a viable candidate. If the Silvertip mating process is anything like our other Shark Mer species, we should present multiple candidates and see if he takes a liking to any of them.’

‘Yes, Ma’am! I’ll start compiling a list right away!’

He smirked at the memory and swam to meet Y/n, his Minnow as he had donned her, at the edge of his tank. She pulled the separation closed for the evening as she entered.

“Good afternoon, Sasuke. How are you feeling today?” Y/n had her wonderful smile as she always did when she greeted him. Sasuke always liked to think that it was different from the smiles she would give to the other Mers she took care of.

“Spectacular now that you’re here,” He smirked up at her as she giggled at his flirting.

“Well, I am very happy to see you, too. I’m always glad that you’re my last stop of the day.” She smiled kindly at him and as much as he didn’t want to fully admit it, it made his heart skip a beat.

“Well, have you heard the news?” He had to stop himself from jumping on her that very moment as he spoke.

“Oh? What news, pray tell?”

“Seems they found a way to repopulate my species even though they couldn’t find a female.” A huge grin split across her face at the news and set the bucket of feed down beside her.

“Sasuke! That’s amazing! I’m so happy for you!!” She called, leaning down and hugging him around his shoulders.

“Believe me, not as happy as I am…” He smirked as he slid his hands around her frame to return the hug, though he made sure to place his hands down low enough to finger at the edges of her bikini bottom’s leg seams. She pulled back from the hug but his arms only shifted to stay resting around her hips. His fingers still lightly toyed with the seams and he was only spurred on by how she didn’t seem to mind.

“So, how are they gonna do it? Artificial Womb? Another species of Shark that’s compatible?” She questioned happily, innocently.

“They figured out that I can mate with and breed a human. So they’re finding me a suitable mate. It’s still a 50/50 chance, like most other kinds of genes, if it’ll be a Mer or a Human. At least that’s what they think. They don’t exactly have a bunch of research to go off of to see whose genes might be stronger. Yet, at least.” He chuckled at his implications that made her blush. “I imagine they’ll have plenty of research by the end of this, though, since as of right now, it’s my job to repopulate my whole species.” Even with his hope and excitement to finally have the opportunity to breed and possibly even claim the caretaker that he’d been watching and yearning for since day one, he let out a rueful chuckle at the reason he even had this responsibility in the first place.

The— rather oblivious— subject of his affections sent him a small, sad smile to soothe him and immediately her kindness brought him back. It reminded him why he liked her in the first place— other than her magnificent body that was practically on display for him day after day in her little swimsuits. He returned a cocky smile and leaned closer to her, his form leaned in enough that she was forced to open her legs to let him settle between them. She still didn’t seem to see anything off about the position even when Sasuke took a deep breath through his nose. He could smell her cunt so close to him and he felt the supple skin of her ass where his fingers dipped under her swimsuit.

He decided to be bold and flexed his fingers to gently knead at the flesh, wiggling his fingers deeper into her suit. Subconsciously, she moved her thighs to try and close around him, just a bit, but it was enough to spur him on.

“I have an idea of a good mate candidate, though. In fact, I’d rather like it to be her. Even if she’s not on the list, I might even request her.” He spoke with a sultry tone, lids hanging low as he let his gaze slide over her form, taking in the swell of her tits in the tight-fitting swim top, up her neck, lingering on the empty canvas of her shoulders and neck, lingering for only a moment on her lips, before meeting her eyes once again.

He was instantly taken aback by the look in her eyes. She tried to hide it but her eyes had always been unwittingly expressive. Especially to Sasuke, he could tell how she was feeling with but a glance even as she did her best to disguise it with a contrasting expression. Even with the happy smile she had on, her eyes shone with a quiet disappointment. Just moments before, before he let his gaze wander over her body, she was truly happy for him and the situation. Happy that he could rebuild his species and bring it back from the brink of extinction.

“What’s wrong, Minnow?” He asked gently, delicately rubbing his thumb over the space where her hips met her ass.

“What? Nothing! Don’t worry!” She tried to smile reassuringly but her eyes still gave her away.

“Minnow, don’t lie to me. You know that I know when you don’t tell me the truth.” His voice turned just the slightest bit stern, just to encourage her to tell the truth. And it worked, her fake smile dropped and she bit her lip nervously with a defeated sigh, averting her gaze to the edge of his tank that still had tooth-shaped dents from when he first arrived as a scared pup, nervous around humans.

“I… I dunno.. I guess I’m kinda.. I dunno, something about you liking someone…” She trailed off and muttered something under her breath that even he couldn’t catch with his impeccable hearing.

“What was that?” He leaned in, head slightly turned to bring his frilled ear closer to her.

“Someone… Someone else…” She muttered again, this time just barely loud enough for him to hear.

“That I like someone else? What do you mean, Minnow?” He had immediately put it together and figured out what she meant. Elation filled his entire being at the revelation that she liked him, too. But he absolutely could not pass up a chance to tease her. It was immediately rewarding when her face flushed with heat and her facial muscles tensed in a way that indicated just how embarrassed she was.

“I-I.. Well.. I mean… It’s just that… Uhm…” She stuttered out, not able to get a single coherent sentence out. If he hadn’t absolutely loved teasing her and flustering her beyond belief, Sasuke would have been pained by the awkward sight. Taking mercy on her when it started to seem like she’d rather be anywhere but there, he put a stop to her sputtering by pushing forward and silencing her with his lips on hers.

She was stunned and frozen, eyes wide and calculating. He pulled back and looked at her with an amused smirk, a brow quirked as if silently asking ‘Do you get it now?’ She remained frozen for a moment, still trying to comprehend what had just happened.

“I-I… What? But… what about who you li-?” He cut her off with a flick to the forehead and a scoff whilst she yelped at the sudden feeling.

“Dummy. I was talking about you.” Sasuke said with an eye roll, still quite amused at her oblivion. Her eyes widened with the revelation and lit up with joy. Before he could tease her again, she launched forward and wrapped her arms around his shoulders to pull him into a deep kiss as she was too stunned to return the first one. With the sudden movement, Sasuke was forced to pull his hands away from her ass to stabilize them before she fell into his tank with the force that she shot forward. He wrapped a strong arm around her middle and grabbed onto the edge of the platform to hold them in place.

He chuckled at her enthusiasm and hummed against her lips as he hoisted her back onto the edge where she was sat. Eventually, she had to pull away for air but kept her arms around him and their foreheads nearly rested against each other.

“So… What do you say, Minnow?” He asked with a husky purr in his voice. Her eyes were glued to his lips, a haze around her mind after a kiss like that.

“Wha..?” He smirked teasingly at her and lifted his hand from around her to lightly grip her chin. Forcing her to look at him, she finally seemed to return to the moment, though she still looked vaguely confused.

“About the scientists’ little discovery?” He reminded her, his Minnow’s eyes lit up with recognition before her cheeks flushed with searing heat.

“I- uhm.. I really.. really like the sound of it…” Her blush somehow increased as her voice trailed off, though he heard her just fine. His sharp teeth peak out when he grins wolfishly at her.

“Well, then. Since I’ve already decided who I want my partner to be, might as well get started, right?” His words were husky with veiled excitement and sent a shiver down her spine, but she still managed to nod bashfully. She quickly glanced back at the separation to make sure it was closed before she carefully scooted towards the edge, making sure that she wouldn’t fall in. Willingly and consciously, she opened her legs even more, a clear invitation. Happy with her compliance, he hoisted himself up and slotted where his fleshy upper half met his scaly tail against her hips with his face just an inch or two above hers.

Without wasting a second, he dipped down to capture her lips again as he ground his genital slit against her awaiting, though clothed, sex. Shifting his weight onto one hand, he moved his other to the hem of her swimsuit bottoms just next to her wet pussy. His clawed fingers teased at the edge, never quite dipping in. He positioned his hand to fan his four fingers over the top of the inside of her thigh, his thumb at the hem. The tip of his finger, careful of his claw, lightly traced the sensitive skin just under it, teasing her even more. She whined into his mouth and just as he began the motion to give in and slide his thumb under the fabric and reach her weeping little cunt, the separation loudly slid open, announcing the arrival of someone else.

The two pulled apart in a panic, though the damage was already done. Whoever had walked in had caught them, though even if they hadn’t, the flushed faces and the way her thighs clamped together like a steel trap would have given them away.

“Well!” Tsunade declared with a single loud clap of her hands. “That makes things easier!” She approached the edge of the pool, pointedly ignoring that she had almost caught the two in the middle of his fingers buried in her cunt had she walked in even a minute later. “Sasuke, I have news for you. We found a way that you can-” She began, about to go on a long-winded speech about their discovery.

“Save my species. Yea. You and your assistant aren’t exactly the most quiet, y’know.” Sasuke cut her off and grumbled, clearly less than pleased that he had been interrupted. Tsunade looked surprised for only a moment before her mind caught up with the events. Sasuke knew about the discovery— that he could breed a human— and he had clearly chosen his future mate and he was ready to get started with the whole process. Perfect.

“Well! In that case, it would be in the best interest of the Research Team to watch you in the act, to help with future cases like this one, and to learn more about your species.” She explained, not leaving room for debate. Great. First, they got interrupted, now they have to wait for those Science Nerds to show up, and they’ll have an audience. Well, That last one Sasuke didn’t mind as much. He could show off that his little Minnow was his. They could watch as he bred her good and full, stuffing her with his cum and plugging her up with his knot to make sure that it took. To make sure that she’d be full with his offspring.

To his— and his Minnow’s— pleasure, it didn’t take too long for the rest of the Research Team to show up. At first, it made her flustered and shy but she was quickly distracted when Sasuke pulled himself back up between her thighs, level with her face.

“Don’t worry about them, ‘kay? Just focus on me. Focus on how I’m gonna breed you full…” His husky voice growled, nosing at the underside of her jaw. He nipped lightly at the skin there and reveled in the tremor it sent through her, even moreso the sweet gasped little moan she rewarded him with.

She nodded and turned her head towards him to recapture his lips. With a pleased rumble, he intertwined their tongues and nipped at her bottom lip with his sharp teeth. His Minnow hummed into the kiss and wrapped her legs around his hips. Gladly, he began grinding against her and appreciated the slickness that was dampening her swimsuit bottoms and soaking through onto his genital slit. They felt the eyes of the Research Team but chose to focus on each other instead. At least, she did. Sasuke kept an acute awareness of them watching them, watching him take what he wanted, what he had been wanting for months.

He reveled in her little moans that he captured with his lips, muffling her even more with his tongue invading further into her mouth. He shifted his weight onto one arm again and quickly moved back to the position he had been in when Tsunade walked in. His fingers toyed at the edge of her swimsuit then switched directions to rub his fingertips over the growing wet spot on the fabric, coating his fingers and claws in her slickness. He hummed against her neck and nibbled the skin to leave a mark on her skin. Gods, he wanted to mark her so badly. Wanted to claim her and make her his forever after but he supposed that would have to wait until after he bred her full.

That was a very efficient claim in its own right. Her moans flowed freely into the air as she tossed her head back and gave him more space to mark up and lave over with his long, rough tongue. He couldn’t wait anymore, he decided, and shifted his hand to the edge of her bottoms again, deftly wiggling under the seam and reaching her bare cunt. She let out a squeak at the sudden, though very much not unwelcome, intrusion, his fingers directly stimulating the sensitive skin.

“Sa-Sasuke…” She whimpered, suddenly aware of how empty she felt, her wet hole spasming around nothing.

“My good little Minnow…” He hummed and pressed kisses down the column of her throat until he reached the top of her translucent coverup. He quietly growled at the layer of separation and reluctantly pulled his hand away from her dripping cunt to rip through the thin material with his claws, eliciting a gasp from his girl. He didn’t pay attention to the little pout she sent him, though he did silently appreciate it, making a mental note to make her do it again.

Quickly enough, he hesitated for only a moment about tearing her bathing suit since it made her tits look so pretty. He compromised with himself to tug at the crisscross straps showing off her cleavage first, watching the way it shifted her breasts and made them jiggle when he released it. He tugged the fabric down over her tit slightly and shifted his hold to cup her breast and manually pull it out the rest of the way, seeing the way her nipple stiffened in the cold air. Only then, after appreciating the sight and locking it in place in his memory, did he hook his clawed finger into the strap once again and snapped it easily enough, letting it unravel until it hung loosely around her neck, the bottom half falling to the ground behind her back with her coverup top.

“Sasuke!” She yelped, “I could have just untied it you know!” She huffed, making him chuckle at her.

“But where’s the fun in that, Minnow?” He teased, cutting off any more complaints by dipping his head to take a nipple into his mouth, swirling his long tongue around the hardened bud.

“Should we prompt him to get to the actual mating? Or-” A member of the Research Team spoke up, sounding flustered at just watching the foreplay.

“No. Let it happen naturally, we would only rush the process if it was detrimental to getting it done as quickly as possible. That would be more likely with a female specimen since most species’ females have only a short fertile period. Males are usually constantly fertile unless they lose potency with old age, but with Sasuke, we clearly don’t have to worry about that. Leave him be.” Shizune reprimanded him, cutting him off sharply and trying to keep her voice down to prevent disturbing Sasuke.

He appreciated the thought but couldn’t resist the eye roll at their discussion, talking like he wasn’t even actually there. He must have accidentally released an unconscious growl because his sweet little Minnow reached her arms up to hold him, tangling her fingers into his hair, encouraging him to switch his attention fully on her again. He sent a grateful look up to her and pressed a soft kiss to her breast before he lowered himself further into the water, moving his hands to hold both of her thighs.

At first, she was confused until he pushed her skirt further up to her hips and tugged at the waistband of her suit bottoms, generously offering her to not rip them to shreds. She let out a breathy chuckle and leaned back on her hands to lift her hips for him. Before he pulled them off, he pressed a kiss to her clothed core, sending a jolt of electricity up her spine. She whimpered when he pulled away, taking her bottoms with her, exposing her dripping cunt to the cold evening air.

He smirked at her reaction and didn’t give her time to readjust before he dove in and shoved his face between her thighs. He lapped at her cunt hungrily and sucked headily on her clit. Immediately, the sensations had her squirming and whining, her hands buried in his hair, unsure if she wanted to push him closer or tug him away from the immense pleasure almost immediately overwhelming her senses. Sasuke hummed appreciatively at the taste of his little Minnow. She really lived up to her name with the way he was devouring her. The slurping sounds resounded all around the shelter around his pool and filled the ears of his good little Minnow, Tsunade, Shizune, and the rest of the Research Team. Most of them shifted in their seats, unsure if they were aroused or envious. A mix of both, they decided.

Letting up on the suction on her clit, he dipped his head down to wiggle his tongue into her, squirming against all the sensitive spots in her cunt. He replaced the stimulation on her clit with his thumb, pressing on it and rubbing rough circles on the sensitive bundle of nerves. The sensations overwhelming her cunt before she could even adjust to the temperature had cries of pleasure soaring out of her throat into the air. When his tongue shifted in just the right way, in just the right spots and his thumb teasing her clit with just the right pressure, she couldn’t hold back the scream of ecstasy or the sharp tug of his long hair as she creamed around his tongue, her juices flowing into his mouth as he kept up his movements. He moaned against her and happily swallowed her liquid pleasure.

He kept lapping at her cunt until she was practically sobbing and pulling at his hair to escape the overstimulation. Granting her mercy, he finally pulled away and pressed an apologetic kiss to her inner thigh, though she could tell he wasn’t sorry in the slightest. She panted to regain her breath from the way her powerful orgasm pulled the air from her lungs. In a soothing motion, Sasuke gently pulled himself up and pressed his lips to the hollow of her throat, stroking over her thigh until she could breathe regularly again. Then, with a deep kiss full of tongue and teeth and passion, he slotted his hips against hers with his member free.

The slick appendage wiggled in the cool evening air in search of warmth to bury itself in. She hummed into his mouth when the narrowed tip stroked over her glistening pussy lips. She was still sensitive from the orgasm he’d wrenched from her but the want to be filled up overpowered the overwhelm of it. Sasuke smirked against her lips and separated their kiss with a trail down to her jaw, then to her neck, then to the juncture of her neck and shoulder. The empty plot of skin was so tantalizing and his teeth ached with the want- the need to sink his teeth into her and fully claim her. Mark her as his.

That’ll have to wait, he reminded himself. Now’s not the time to focus on that. Now is the time to breed her greedy little pussy. Fill her up with pups and keep on filling her up, over and over again. She’s a good little girl, so eager for being knotted and bred. She’ll be an even better little mate, he encouraged himself in his mind to wait just a little longer. Just a bit longer and she’d be his good little mate. First, he had to thoroughly breed her tight little cunt. With that thought in mind, he pushed forward, pressing his length closer to her entrance. His long, slimy tongue laved over her skin as he nibbled and sucked on the skin to leave little marks that would satisfy his urge to claim her for now.

“Fu-u-uck, Sasuke..!” She called, circling her hips to try and coax his cock into her. When it didn’t work at first, she wrapped her legs around his form and pulled him closer, her one arm wrapped around his shoulders, the other working with his to hold them steadily on the edge to not fall in. His other hand still kneaded at her thigh and precisely dug his thumb into the flesh to coax it more open to her pretty little pussy.

“Don’t worry, Minnow, I’ve got you.” He muttered against her flesh before he pulled back to rest his forehead against her shoulder to look down at where they would soon be connected. Looking past her tantalizing tits, he watched as his member squirmed against her, sliding through her folds in search of her greedy hole. Finally, it caught on the edge of the convulsing muscles and immediately began slithering in. The Research Team all jolted to lean forward when she sharply inhaled a gasp. The guy from before seemed the most interested. He was leaned forward the most and his gaze was heavy. The way he stared so intently made a fire burn in Sasuke. It was a mix of jealousy and pride, though it was more cockiness than pride, really.

It infuriated him that someone would look that intently at his mate, especially when she was so vulnerable. So exposed. His instincts yelled at him to cover her whole body with his own, even pull her into the water away from prying eyes but logic, thankfully, won out knowing that it would be dangerous as his little Minnow, despite her nickname couldn’t breathe underwater. Yet, he reminded himself, once she was good and full with his pups and claimed, her body would undergo changes to properly care for the pups for the chances that it was a mer. The cockiness reinforced his reasoning, as well. The cockiness that cried out in pride that she was his mate. That the bastard could look all he wanted but his good little Minnow was his to touch. His to hold. His to pleasure and enjoy.

Nonetheless, the mer lowly growled from where his head rested on his little mate’s shoulder, side-eyeing a glare at the man with a cocky smirk pulling at the edge of his mouth. The hand around his shoulders slid up to his hair and gently carded through it, soothing him back to the moment where he was about to fuck her senseless. Almost immediately, a low rumbling emanated from his chest, it was almost like a purr. With a shocked giggle bubbling from his Minnow’s throat, Sasuke quickly diverted her thoughts to her throbbing core once again when he quickly canted his hips into hers.

The gasp she let out was rewarding and had him rumbling deeply in satisfaction. He buried himself to the hilt and stayed there for a moment to let her adjust. He knew he was larger than most human males— a fact that filled him with pride— and that his phallus was greatly different from them, shape, texture, and mobility-wise. His cock squirmed inside her, satisfied with the heat, and moved in search of her pleasure spots. His instincts led him to wanting to pleasure his partner just as much, if not more, than the pleasure he received. His instincts knew that if his partner orgasmed it heightened the chances of his seed taking. As if he needed any help. His species’ seed was very potent and his thick, firm knot would keep his mate plugged up to ensure that none of his seed leaked and lessened the chances of impregnation, even if only by a fraction. With the stream of sharp, almost surprised moans and gasps coming from his mate, he could tell his phallus was doing its job.

“F-fuck- Sasuke- Sasuke, please~!” She whined, burying her hand firmly in his locks, though not tugging. Her incoherent plea was enough for him to comply and rest enough weight on the hand planted on the firm round behind her to easily use his other hand, wrapped around her hip with a tight grip, to move his hips back. The water rippled behind him and splashed quickly up against the corner wall of his pool and hitting the backs of her thighs and the top of his tail as he snapped his hips forward again. He did this a few more times, slowly pulling out until only his wriggling tip stayed inside her wet heat and thrusting his hips forward quickly and powerfully. He tried to keep up the teasing pace but he couldn’t take it anymore.

He needed to breed her. Breed her tight little pussy. Fill her up with cum and make her belly swell with his young. With surprising speed, he set a bruising pace and filled her clenching walls with his wriggling cock over and over again. He could hear the Research Team mumbling amongst themselves, comparing notes or some shit that he couldn’t bring himself to care about but the noise itself was enough to ignite his possessiveness. The hand planted on the ground clenched and scratched at the cement. His sharp claws dug into the hard surface and scraped deep lines into it, taking the rubble with it. His other hand gripped tighter and ended up ripping her skirt where it rested around her hips. He paid little mind to it— as did his good girl— and simply kept up with his pace, though he vaguely recognized that the material was essentially unsalvageable with tearing it so much whilst it was bunched up the way it was. With a growl and a fire lit in his eyes, he smashed his lips against his Minnow’s and claimed her mouth all over again. His tongue delved deep enough to almost choke her. She didn’t gag but her throat lightly convulsed against the foreign feeling before he pulled the appendage back. He only wanted it to be pleasurable for her. No discomfort.

His hips kept up the heavy pace as he buried himself to the hilt again and again. Pulling back from her lips, a thick strand of saliva kept them connected before he leaned back in and licked it away from her kiss-swollen bottom lip. As if on pure instinct, he immediately shifted to her neck and left bites and hickeys on the side he hadn’t yet marked up. All the while, he never relented on his pace, water splashing around him and creating small waves into the rest of the vast water at his back. His member continued to squirm inside her, aiming for each and every one of her pleasure spots and slipping easily into all the nooks and crannies of her inner velvety walls.

Her voice trembled as she cried out in pleasure and shifted her hips to meet his thrusts, subsequently forcing his cock deeper inside her. The pointed tip was forced all the way to her cervix. The wriggling pointed head met her cervix directly, immediately beginning a venture to enter the deepest part of her. Sasuke and Y/n both let out groans of pleasure at the feeling, hers more a surprised noise quickly transformed into a drawn-out whine of bliss while his was one of pure ecstasy at the feeling of claiming his Minnow so deeply. So deep inside her that no one would ever be able to claim her as he had. Not that anyone else would ever get the opportunity to try. No, she was his mate. And he would ensure that her body knew that by thoroughly breeding her over and over again. She would not be without pup for long, breeding her to her heart’s content.

Without much reprieve, Sasuke returned to his brutal pace, jackhammering his hips into hers as he buried his face in her neck. His claws dug heavily into the pavement, cracking it even more with his strength and his other hand kept a bruising grip on her hip, not that she minded the marks it would leave behind. His marks. Her walls fluttered around his cock as he mercilessly pounded into her. Her moans echoed around the walls and went higher in pitch when the cord in her belly was pulled taut again.

“Sasuke- Fuck- Please!” She whined and bucked her hips. The Research Team, from their positions leaning forward to see the pair better, could see his muscles contracting and his hands gripped tighter— though he remained aware and careful with his hold on her flesh. They could tell he was rapidly approaching his climax and they were all on the edge of their seats— literally and figuratively— to see it. His thrusts slowly became sloppier and his grunts and growls became more frequent, his nips at her neck did, too.

What the scientists couldn’t see and his little Minnow hadn’t noticed was the swelling bulge at the base of his wriggling cock. It was stiffer than the rest of his member and steadily grew in size and mass. As his thrusts gained more reckless force and speed it began to catch on the edge of her hole. That made her notice. When she felt the bulging knot catch on her hole a louder moan ripped from her throat. The wide eyes of the Research Team snapped to her and watched her come undone. Her back arched, her toes curled, her nails dug into his shoulder and scratched angsty red lines into the skin, her mouth hung open in a silent scream as she gushed around his member. The convulsing and contracting of her walls around him had Sasuke closer to his own end.

His knot swelled to full size and with a final rough thrust, it pressed hard against her gushing little cunt before it popped inside her. Another wave of ecstasy rushed through her and sent her into another wave of orgasm before her last one even finished. A loud, high-pitched cry escaped into the room and practically vibrated the walls. Her orgasm’s ecstasy lasted for what felt like forever as his white hot seed shot into her. His narrow tip had wiggled past her cervix and sent his cum directly into her womb. His potent seed filled her up and filled her lower belly with delicious warmth that kept her in a state of blissed-out pleasure. She shivered in her fucked out haze as Sasuke filled her up with spurt after spurt of spunk.

“You did so good, Minnow. My good girl, took my cum so fuckin’ well. Gonna be such a good momma.” He purred in her ear, licking the spot just under it.

“Is it done? Did he do it?” The guy spoke lowly to the rest of the Research Team and Y/n and Sasuke barely resisted the urge to roll their eyes.

“If I had to take a guess, I’d say yes.” Tsunade said sarcastically. Sasuke licked at the bites and dark hickeys on his Minnow’s neck and shoulder to soothe any aches and to help the deeper ones heal faster. His member pulsated inside her as he recovered from his powerful orgasm. He had touched himself before to the thought of her but he never could have anticipated just how good she felt around him. He felt like he was in Heaven with her so tightly wrapped around him. Her heat clenching around his cock so snugly.

In the afterglow of their orgasms, Sasuke felt his arm getting tired from holding himself up and his tail aching from exhaustion from thrusting inside his little mate while keeping himself from falling back into the pool. Carefully, he maneuvered her in his hold to gently pull her into the water with him, though making sure they didn’t go under. Her grip on him tightened and her other arm shot to wrap around his shoulders making him chuckle. The deep sound sent a shiver down her spine and a blush to her cheeks as well as a vibration through her body from where their chests were pressed together. As an afterthought, Sasuke quickly discarded the ruined fabric of her skirt to the edge of the tank before he continued on with his movements with her.

“Don’t worry, Minnow.” He cooed to her as he moved to float on the water with her on his chest, slightly swishing his tail to keep them afloat. “I won’t let you fall in. Promise.” He nosed at her temple and pressed a kiss there.

“How do you feel?” Tsunade asked, addressing his little Mate.

“Full. Warm.” She spoke dazedly, snuggling into his chest comfortably.

“Good. From the looks of it, you should be pregnant in no time. We’ll monitor your progress and stats to make sure everything is all good and we’ll set up on-site lodgings for you. Let us know as soon as you find out when you’re pregnant. Since we observed this time, we technically don’t have to observe more of the breeding and mating but if it didn’t take this time, I’d like to observe your next session just to see if there are any differences, if that's okay with you. And, I’d like to ask, is there anything that we didn’t see that happened?” Tsunade inquired, eyes flicking between the couple and her notepad.

“Well.. Right now, we’re stuck.” Sasuke’s little Mate spoke softly, almost unsure.

“‘Stuck’? What do you mean?” Shizune asked, incredibly intrigued.

“I knotted her. We’re tied together until it goes down.” Sasuke spoke up, his voice slightly annoyed like he wanted this to be over and to have time alone with his good little Minnow.

“So you’re species has a knot! Interesting!” She spoke excitedly and quickly scribbled it down in her notepad. Sasuke huffed and nuzzled into his Mate’s hair and inhaled her scent. Her scent, enhanced by the vigorous physical activity and it sent a fuzzy pleasurable haze to his brain that had his chest rumbling with a purr.

“Well, I don’t believe there’s anything else we need to observe, so let’s all head out and leave the couple be. And yes, that means everyone.” Tsunade spoke, adding sharply at the end as her harsh gaze landed on the guy that had been far too invested with the view. Sasuke, glad that the woman had realized their want for privacy, let out a small, quiet sigh of relief and watched them all file out. He glared and bared his teeth at the guy who insisted on leaving last and walked slowly to glance back at them. When he saw the Mer’s expression, he quickly filed out with the others. The raven-haired Mer stroked over his Mate’s bare back and soothed her hip where his grip had surely planted bruises.

“Gonna be such a good momma to our pups. Such a good mate. So so good.” He cooed at her and planted kisses on her face before landing on her lips. It was sweet compared to the rough, lustful, and debauched kisses from not long ago. His cock remained buried inside her with his knot plugging her up to keep his hot cum, his potent seed inside, to make sure she was properly and thoroughly bred. She hummed happily against his lips and relaxed against him as he slowly guided them to the small island trainers coaxed him onto during shows where they could simply rest.

Once they were settled, it didn’t take long for them to drift off, pleasurable heat warming them both and lulling them into a comfortable state. His knot remained full whilst they drifted and stayed as such for a while after they fell asleep. His member easily slipped out of her and back into his sheath once his knot softened enough. They stayed comfortably cuddled together until morning when the sound of the separation sliding open echoed in the otherwise silent area. In walked Shizune with a towel, clothes, and a kind smile as she approached the edge of the pool.

“Good morning. I know your clothes were, unfortunately, damaged,” she sent a teasing look at Sasuke who blushed and looked away with a small ‘hmph’, “so I thought I’d bring you a change of clothes. I’d also like to give you a small physical check-up after last night to make sure everything is all good and dandy. Afterwards, I have breakfast inside for you.” The kind woman spoke gently with a soft gaze.

“Oh, thank you, Miss Shizune! I really appreciate it.” Y/n smiled at her and looked back at Sasuke to silently communicate if it was okay for her to leave for a bit. He wasn’t quite pleased with it but he knew it was more than reasonable. To show his understanding he leaned up and captured her lips sweetly as his hands softly ran over the skin of her back and sides. Carefully, she lifted herself off of him, slightly wincing at the soreness in her hips and between her thighs. Instantly, he moved and held onto her firmly as he maneuvered them both further into the water to swim her back to the edge. Kissing him in silent thanks, she climbed out and accepted the towel with a smile at Shizune.

“See you in a bit, Minnow,” Sasuke said, he rested his chin on his crossed arm on the edge and looked up at her, admiring the view of her naked body. He was so used to staring at her in her cute little swimsuits and just imagining what she would look like without the coverage and actually seeing it was so much better than anything he could have imagined. The planes and curves of her body were so enticing that he knew he would never get tired of seeing her bare like that. Seeing her stomach as she dropped the towel to put on the clothes Shizune brought, he couldn’t wait to see it swell his child, to have physical evidence that she’s his.

“See you soon, love.” She cooed back at him as she pulled the shirt over her head after she buttoned the skirt closed. His whole face perked up at the nickname and he couldn’t stop the purr that erupted from his chest. Chuckling, she kneeled down and pressed a kiss to his forehead before she stood to leave.

Exiting the shelter, she saw that the separation to the Aquatic Water Serpents was open while the morning crew did their rounds and fed the Mers, and performed check-ups if necessary. The younglings were occupied with the feeders and if any of them needed check-ups while Iruka was freely resting in the tank. When he saw her and Shizune passing by he quickly made his way to the edge to get to them.

“Hey.” He got their attention with a hiss, though remained quiet enough to not attract the attention of the younglings, “You’re lucky the younglings were already asleep down in the cove with how loud you were being.” He hissed out with a slight glare with no real heat behind it. Instantly, her face erupted with heat as her eyes widened in mortification. With a shrill whine of embarrassment, she buried her face in her hand with a muffled apology to the serpent. With Sasuke’s separation left open for the morning crew, he heard Iruka’s words and smirked. He was suddenly smug like he had never been before. A cockiness filled his chest as he reveled in the knowledge that he had made his Mate feel so good that she was loud enough to be heard through the walls. Instantly, he made the decision to ensure that he always made her feel that good.

He’d have her screaming his name every time.
