Work Text:

The night was young, but the day was long, and that alone left the two Sinners exhausted. Their day consisted of Mirror Dungeons, Mirror Dungeons, oh, and would you look at that, more Mirror Dungeons. There was only so much a group could do before calling a quits, and the two veterans reached that point not too long ago. Both were laying on Gregor's bed, of course not because he willingly let the shark boy back with him, but more because the fish let himself in and made himself at home. The roach was simply too tired to argue.

A lengthy sigh left the roach's lips as he sprawled out on his bed, accepting the fact Nemo had claimed his body as a cushion. The fish flipped around so he was now laying on his stomach, cocking his head to the side slightly as he chirped curiously, wondering why his pillow sighed.

Gregor simply shook his head, "It's nothin', shark bud." He grinned, patting the lad on the head, nails running along his scalp, of which the black haired man more than happily leaned into, melting into his touch, urging the older male to scratch harder. Though, the expression Nemo gave in return didn't quite believe what Gregor stated, especially as his large tail began to thump on the ground, there was something on that man's mind. The roach shook his head once again, his lips curled upwards as he continued to scratch the lad like a cat, laying his head back on his pillow to stare at the ceiling.

"Don't believe." Nemo grumbled, his voice hoarse as ever, mushing his face into Gregor's chest as he pulled himself further up the man's length.

Gregor simply hummed in response, closing his weary eyes, wanting to call it a night early.

The thuds grew in strength, and volume, as the fish grew even more frustrated by the lack of a proper answer.  Low growls emanating from the smaller figure who began to nip at the roach's shirt, tilting his head to allow his cheek to rest on one of Gregor's pectorals, his bright yellow eyes narrowing dangerously in annoyance.

"Enough of that, brat." Gregor huffed, cracking a single golden orb open to stare at the man on top of him.

Nemo shot up, straddling Gregor's torso as he leaned in dangerously close to the roach's face, both of their noses nearly touching. He sounded much like an irked dog than a person in protest of being called a brat with those growls that were reverberating from his throat.

The roach simply stared at him lazily, clearly unimpressed by this, "You can't even deny that statement, shark bud." He states plain as day. Everyone who knew the fish knew he was the king of brattiness, but also knew he was in the greatest stage denial.

"Tell!" The fish barked his nose scrunching up as his thick brows attempted to clash together.

Placing a finger upon the shark's nose to stun him, gently pushing back without any semblance of a fight, Gregor smirked, wanting to be the one doing the teasing for once, "Ah~ I think I won't." He didn't move his finger from the boy's nose, wanting to observe the fish's frustration as he continued to deny the lad any semblance of a hint as to what was on his mind.

A loud whine. That was all Nemo was able to muster up, his body feeling like a wet pool noodle as he was in that trance-like state of tonic immobility. Curse Gregor for knowing this one weakness of his! The lad couldn't even remember how the roach found out about his nose being his weak point, probably a book or something, but he used it to his full advantage when needed.

Seeing the boy in such an annoyed state was quite amusing, the roach had to admit, but he knew if he lingered for too long he'd risk losing a hand as soon as he released the boy. Lifting his insectile arm to poke the fish's chest, he smirked, "Since you like to hear me beg so much, why don't you try, eh?" After saying what was needed, he lowered his hands, shifting his body so he was sitting up and Nemo was now on his lap.

Nemo lifted a brow, beg? Him? Oh, if he wanted begging he'd get it. Just not verbally, nor sincerely. Fine. Have it his way. The tiny terror grabbed onto the front of the taller man's shirt, his face pressed flush against Gregor's chest as he gazed up with the biggest puppy dog eyes he could muster, blinking them a few times as he whimpered pitifully, batting those lashes all the while.

Gregor wasn't expecting that at all. That was the furthest thing he had expected. It was hard to resist, if he had to admit it. The bug blinked a few times, clearing his throat as he looked away, "Ehrm... Ah... You're gonna have to do better than that, yeah?" Oh that wasn't convincing at all.

He was met with a pound to the arm and a fiery glare. An audible exhale of frustration came from the lad as well. He was daring Gregor to keep being stubborn and see where that'd get him.

Taking note of how annoyed Nemo was getting, he decided it may be a good idea to back down early. Wrapping an arm around the man's waist he holds the lad tight, "Okay, okay, you win." He surrenders playfully.

"Tell. Now." The boy hisses as he melts into the bug's touch.

"Haaa..." Gregor sighed, debating with himself for a moment, "How do I put this...? I know you have that... slit thing..." He wasn't exactly sure as to what the cloaca was called, "where you keep your dicks..."

The shark creates a noise of acknowledgement, urging the roach to continue on.

"And well... I was wondering since it's a slit..." He hesitated, "Ah... I was wondering if I was able to do you from the front, yeah?" 

Nemo's brows shot up, eyes wide in surprise at the boldness of the answer. A little 'heh' came from the lad as he smirked cockily, wiggling out of the taller's hold to lean back, supporting himself with one hand, the other on his belt, "Try?" He enticed smugly.

The roach sat there dazed for a moment, his mind trying to comprehend what just happened. He was expecting Nemo to call him weird and that'd be that, but he wanted to go along with this weird idea? He wasn't going to say no, after all, this was his idea, but his mind wasn't wanting to get the show on the road yet, "Are you sure?"

An enthusiastic nod followed by the jingling of metal on metal responded to him.

Oh.

Oh.

He was super serious.

By super serious, it meant the fish was nearly naked at this point. Already down to only wearing his pants. The lad sure didn't waste time when it came to stripping, that's for sure.

Gregor stared, admiring the man's untainted - in his mind - pasty white flesh that was still littered in light pink haphazardly placed scars. How such a creature likes him, he'd never truly understand, maybe it was their shared struggles they went through in solidarity that bonded them together. One thing was for sure, he was always impressed by how fast the fish could throw off his clothes. Then again, having two hands does help that out.

While Gregor was busy staring, he stood up on the bed awkwardly, doing his best to keep his balance as he slid his pants down, kicking them off somewhere away from the two of them. Now completely in his birthday suit, crotch around eye-level with Gregor's face, he showed off his cloaca proudly, slightly opening it to show the roach the inside.

His genitals were a mix of human and fish. A normal male shark would have a pair of claspers outside their cloaca, whereas Nemo's own pair of humanoid claspers rest inside his cloaca. The other difference was his cloaca only really worked as a pouch to hold his genitals rather than the rest of his digestive system. It was strange the scientists at G Corp. decided this was that they wanted to invest their money into, but they sure did it. To fuse a human's and a shark's reproductive organs into one was quite the... Interesting choice.

Gregor snapped out of his daze, observing the hole in front of him. Shakily, he lifted up his human arm, bringing it close to Nemo's opening, his golden gaze trailing up to meet the fish's own, "Ehrm... M-may I?" He stuttered, earning an enthusiastic nod in response.

This was new for him, sure, he's seen Nemo fish out his junk from in there before, but never has he himself even thought of digging his fingers inside. Cautiously, Gregor inserted a finger into the cavern, earning a low groan from the lad. Taking that as a good sign, he began to feel around the walls. They were wet, much like a woman's sex. He was not expecting that in the slightest, especially when he began to insert his finger deeper, feeling a little bump on the inside.

Nemo nearly lost his footing as that bump was poked, a drawn out moan letting loose from this soft lips of his. He unconsciously grabbed onto Gregor's head to steady himself, pushing the man towards his crotch. His legs were shaking, his tail thumping against the mattress, trying to get his little braincell to piece together what just happened.

Looking up in just as much shock at the other, Gregor blushed deeply, "I-... I guess that felt good?" He sputtered, a sheepish half-smile forming on his lips, his glasses somewhat crooked on his nose from colliding with Nemo's groin.

Nemo simply wiggled in response, not wanting to admit it as he looked away, his cheeks tinted with a splash of pink.

Deep chuckles resonated from the brunette at the smaller's reaction, poking that little lump once more. Down fell the shark man with a loud cry, covering his face bashfully, trying to etch out the thought of his legs giving out beneath him. That took Gregor's hand with it, lowering down as his fingers were still inside, prodding harder at the internal nub. "Woah, easy there, shark bud." He jest, shifting to rest his chin on Nemo's shoulder, giving the boy's ear lobe a nip, earning a shuddered breath as a prize. It was rare Gregor got to feel so in control, especially with someone like Nemo who had this natural aura of dominance around him, minus the height that made it a little hard to take seriously.

The fish didn't remove his hands from his face, he inhaled shakily, his body trembling in pleasure as Gregor began to add another finger to thrust in and out of his sensitive slit, those digits brushing past his sheathed members to ram into that ball of nerves. He was never going to admit that he was enjoying this, not so long as he was alive. However, he couldn't hide his tail ever so slightly beginning to wag, encouraging the roach to continue his assault.

"You're enjoying this, ain't'cha?" He teased, "Wish I got this lucky with what they did to me." He darkly joked, their shared unfortunate circumstances allowing him to, "Here I got this cursed arm, and you got two dicks. I don't think it's fair, yeah?" As the roach spoke, he picked up the pace, the flat side of his chitinous arm carefully wrapped around Nemo's lithe body as he continued to finger the boy's cloaca.

A gargled, "Nnnghh..." was all the lad responded with, trying to hold back the creeping vocalizations that wanted to vomit outwards into the air. Baring his neck, he allowed for Gregor to pepper kisses along the supple flesh, a fiery trail of sensations being left it their wake. God, this felt amazing, he had never felt such sensations, it felt completely different than when he was taking it up the ass and his prostate was pounded into oblivion. Just one little poke to this bad boy had him weak in the knees, two made him collapse!

Humming in approval at Nemo's actions, the roach added another finger to the drenched slit that was beginning to overflow with juices. Three fingers was getting a bit crammed, seeing as the man's cocks were still inside. This frustrated Gregor slightly as he wasn't able to get the angle he wished now, and knowing that Nemo enjoyed his back half to be filled to the brim - the little size queen he was - surely that meant he'd want the front to do the same. With that in mind, he hooked his fingers around one of the twin rods and plucked it out, repeating with the second until the two leaky poles of flesh were exposed to the elements.

The lad was slowly becoming a whimpering mess, his breathing becoming more and more labored as Gregor continued on. His voice going up an octave as his cocks were now exposed. Mindlessly, he grabbed Gregor's wrist, urging him to reinsert his fingers into him, begging to feel that jolt of pleasure once more. He couldn't control the little humps his hips were making as he wordlessly pleaded for more.

"Alright, settle down, shark bud." The middle aged man commanded lightly, grinning at the urgency that was behind the younger's actions. He lightly dragged his fingers along Nemo's weeping, open slit. The boy shuddered in anticipation, his body's movements insisting on him hurrying up. Hurry up he did, because he plunged those three fingers inside, immediately bullying that lump once more.

The fish's back arched back as he released the loudest moan, his eyes rolling back as his tongue lolled out the side of his mouth. That was it~ His breathing picked up, becoming more ragged as he manhandled Gregor's wrist once again, humping his hand desperately, his own digits forcing Gregor to insert a fourth into him. He was on cloud nine, absolutely lost in the sauce. The brain fog that enveloped his mind was growing stronger by the second, the knot in his stomach growing tighter and tighter as Gregor's fingers poked and prodded around his opening. He could care less if his cocks were being pleasured, but that spot? That little lump he didn't even know he had? That needed to be pounded now and hard.

Nemo was moaning Gregor's name in that raspy tone, his throat feeling raw as he began to overexert it. He released the most pitiful whine, caked in need, as the roach removed his fingers from Nemo's hole. He pitifully tried to grab his hand back, he needed to feel full again, he was almost there!

"Hold your horses, shark bud." Gregor firmly scolded the panting, whining mess that was on top of him. His now soaked hand was reaching for his own belt, but those sharp eyes the fish had beat him to the punch. Lithe hands finagled with his belt, flinging it violently to the side, practically tearing open the roach's pants as he pried the man's rock hard, fat cock free.

"Mine. Mine. Mine." Nemo possessively repeated, a frantic need evident in his tone and actions as he scooted off of the man's lap to lay on his back, making sure his tail was off the edge of the bed off to the side as to not lay on it,, pushing his twin rods to either side in order for him to open up his flooded slit. His eyes were pleading with lust for Gregor to insert himself, his chest moving up and down as he panted heavily, his gills flailing with each breath as well.

Gregor had never seen such a side to Nemo. He was used to the man being assertive when it came to sex. Well, yes, this was assertive in a sense, he wasn't like this. Could this be what they call a 'bitch switch?' He has seen the boy in heat-like states before, but never to the point where he was willing to be a pillow princess. A frustrated hiss broke Gregor out of his thoughts, showing the lad was becoming impatient with his inaction. He shifted in order to over over the fish, positioning himself awkwardly by supporting his body up with his human arm, but leaning his insectile arm lower to bend at the joint - he wasn't really liking the sound of having a hole through his mattress - thus giving him a lopsided posture as the fish took it upon himself to line Gregor up with his cloaca.

With a swift thrust inside, Gregor sheathed himself within Nemo's slit. It was surprisingly tight, but the torrent of slick that was filling the interior was what really got him. Sure, he knew there was quite a bit in there from what he had felt, but it was literally gushing out once he took the plunge, it looked like a tiny waterfall.

Nemo quickly locked his legs around Gregor's waist, earning a groan of both pain and enjoyment. Mostly lower back pain that came with age, though. Then the humping began again, Nemo started lifting his hips to meet Gregor's own, urging him to get this show on the road. The roach was more than happy to follow that idea. He steadily began to back out, then thrusting harshly back in, causing the lad to gasp, his arms now wrapped against the roach as he found the man's head, his fingers tangling mindlessly into those brown locks. The two veteran's lips met, melding together as they allowed their tongues to creep inside each other's mouths, fighting for dominance. For once, Gregor won, all he had to do was surprise the fish with a snap of the hips, bursting his concentration, finally being able to taste Nemo's inner workings at the cost of his poor tongue. Gregor noted to not do that again, because fresh blood began to pool on his tongue as he grazed those sharp chompers the lad possessed.

Moans and groans filled the room in no time. Their sounds were music to each other's ears. A harmony of carnal desire and need. They were mating. The roach's thrusts became more erratic as time passed by, his rhythm becoming sloppier once Nemo's orifice tightened around him further. They were both reaching their boiling points, ready to spill over any time now. Nemo's fingers were tightening their hold on Gregor's hair, pulling him back to gaze into each other's lust-filled eyes, both glazed over with an animalistic greed.

"Gghh... F-fuck..." Gregor groaned, biting his lower lip, shutting one eye, he was close, he knew it, he could feel that coil in his stomach tightening further and further. The dam was about to break and he could tell. "N-Nnnnnemo... I'm close..." He stuttered out, his hips never ceasing their movements that the fish happily met with his own.

The lad's legs tightened around the older man's waist, acknowledging the statement without a word. He's been close himself, but has held back, wanting Gregor to finish first in fear of possibly loosening up.

Minutes passed by before Gregor did one last powerful thrust into the fish, burying his face into the crook of Nemo's shoulder as he growled barbarically, pouring his hot seed into the boy's opening, filling it up fully, allowing it to overflow onto the bed without a care in the world.

Nemo's eyes snapped open as his back arched, leg-locking Gregor into place, his own twin cocks shooting their own rounds once Gregor's seed began to fill him up. It was so warm. So filling. He felt whole.

The two took a moment to recollect themselves before either even dreamed of moving. They were panting hard, their bodies sweaty, and legs all felt like jelly. That was an intense session.

Gregor was the first to recompose himself. Slowly, he sat up, pulling himself out of Nemo's slit with an audible schlorp. He picked the boy up with his single arm, flipping them to how they originally were laying, "That was..." He sighed blissfully, "absolutely amazing, shark bud." 

A pleased string of grumbles and grunts reverberated from the lad, his limbs feeling limp as he allowed his body to be maneuvered back to how they were prior. He never guessed that his cloaca would feel so good. But what exactly was that nub inside of him? Surely that couldn't be what he thought it was. Deciding to put that out of his mind, he closed his eyes, drifting in and out of consciousness from sheer sexual exhaustion.

"H-hey! You can't fall asleep on me yet!" Gregor barked, "We gotta at least shower first and get some new sheets. Don't want to be sleeping in our own cum, yeah?" He joshed, but was entirely serious.

Nemo didn't care, he was pooped and he was sleeping one way or another. He grumbled, limply waving a hand around.

"Fine, you rest, I'll bathe you." Gregor begrudgingly agreed.

Needless to say, both were out until Dante was sent to fetch them the following morning as both overslept. Their manager wasn't shocked in the slightest to say the least.

 

 

Notes:

I was originally going to try and write a Nemo / Gregor omegaverse fic tonight but here I am, writing porn about Gregor fuckin Nemo's cunt.
Lowkey debating on if this makes Nemo intersex or not. But I think it now does since I gave him a g-spot. ¯\_(ツ)_/¯
Who cares as long as shark boy gets plowed by bug man.
But for real, do give me opinions on that. It'll bug me if I don't figure this out. ( Pun intended )
If worse comes to worse, I just say the G Corp. researchers had some messed up fetishes or something idk.

Also, side note, this is shorter because my keyboard is currently deciding to be funky and wanting to double type most of my keys, and it's REALLY FUCKING ANNOYING. So y'all only get 3.5k words this time.
