Chapter 1: Chosen
He was tired; not just tired, but weary down to his very bones. Fresh from a magical creature trafficking bust, he was practically dead on his feet. He had been well and truly ready to go home after he had just finished his preliminary paperwork when a squeaking little note had crawled onto his desk and unraveled into his hands with a flourish. One of his informants had intel about the rash of strange “gas explosions” across the city. They hadn’t really been gas explosions, of course; merely a fabrication that had concocted the moment they saw the severity of the destruction.
Got info on your dark cloud.
I’m not sticking around, you’ve got one shot.
Graves frowned. It was unusual to hear from Gnarlak directly; even more so not to be directed to just meet at his pub. Whatever information the goblin had for him, it was good and it was dangerous – not to mention expensive, no doubt. Graves sighed and stood, his head heavy between his shoulders as he braced himself against his desk for a moment. He took a deep, trembling breath and tried to ignore the ache in his ribs from a potshot one of the traffickers had managed to strike him with. He hid it well until now, unwilling to worry his aurors, but he knew what must lay beneath his vest and shirt. He could feel the heat of the injury through his thin clothes when he brushed over it with his fingers. He knew the skin beneath was no doubt hot with internal bleeding, mottled and purple. Perhaps even somewhat uneven, if any of the bones were broken.
Consumed as he was in his evaluation, he didn’t notice when his most junior auror slipped through his door carrying a mountain of paperwork. Jace Wayland was a thin, willowy thing. Baby faced with big blue eyes that could stop people in their tracks. In all honesty he looked nothing like an auror. He looked as though a good, firm breeze could knock him over; but he was tenacious – more so than Graves had encountered in a junior in a long time. In what he lacked physically, he more than made up for mentally. Sharp as a tack and faster than even his best investigators, although he had never told the boy that. Humility bred caution, after all, and he wanted the boy to make it to a full position. Curious if he could.
“M-Mr. Graves, here are all the leads you asked for me to follow up on while you were out…”
Graves heard it the moment the boy’s words trailed off, the moment he noticed the director’s grimace. IT was too late to cover it up now; the boy knew. He cursed beneath his breath.
“Mr. Graves, are you hurt?”
Graves sniffed loudly and slowly straightened his back into something more regal and commanding than the figure he no doubt cut while doubled over on his desk. He ignored the fiery blaze of agony blaring along his right side and addressed the boy as if nothing were the matter.
“Mr. Wayland... It’s late, why aren’t you home?” He asked. Annoyed to have been caught when no one should be left at the office. Impressed, however, by the child’s drive.
“This seemed important,” the boy said lamely.
“Everything will always seem important,” Graves said, knowing full well the irony of the words leaving his lips. The pot calling the kettle black. “You must take time to recharge or you’ll drive yourself mad.”
“O-of course,” Jace said, but his eyes were still on Graves’ ribs and he knew the subject wasn’t done. “Did the raid go well?”
“Swimmingly,” Graves said shortly as he drew his coat from his chair and made a show of putting it on without ever once letting slip a grimace. Even when he felt something distinctly pop. He began to sweat. “The traffickers were apprehended with minimal casualties to either side.”
“That’s great news. Are you headed home?”
“Not quite,” Graves said, fingers trailing over the little worn out note on his desk before he set the little slip aflame.
“But sir, you—“
Graves shot him a cold, challenging look and watched the boy’s confidence wilt before his eyes. Surprisingly, however, Jace simply clutched his papers tighter and frowned.
“We’re not supposed to do anything alone, sir.”
Graves scowled. The boy was right. It was a rule that they were not supposed to act on any lead alone. Clever child, he saw the note for what it was and knew exactly what to say. What sort of leader created rules they did not themselves abide by? Graves glared at him, assessing, before finally he let loose a small sigh and said, “Get your things, Mr. Wayland. Let’s make this quick.”
The boy scampered off before Graves had so much as a moment to change his mind and somewhere in the back of his head, he felt a niggling. He scowled, but the feeling was lost to him before he could think much more of it – burned away by the low, hot hum of his aching ribs.
The docks were quiet; silent in a way that set Graves’ teeth on edge. There was no late night rush of strangers wasting their money at the dingy bar down the street. No dock workers, no gulls. Something was terribly wrong, Graves just didn’t know what.
What he did know was that he was cold, but also hot. There was a thin film of sweat growing at his brow, and he felt simultaneously smothered by his coat and scarf, and freezing. He shivered despite himself, his eyelids heavy, and clenched his fists a little tighter in the safety of his coat pockets. It was ten past midnight and that rotten little goblin had stood him up. He should have known better than to trust the creature; wicked and cruel as it was. Gnarlak was a valuable informant, but he wasn’t exactly a trustworthy one, and Graves was just beginning to wonder if he should stop by The Blind Pig and have a little chat about certain privileges the goblin was enjoying when Jace finally sighed beside him.
“Well that’s rather disappointing,” the boy pouted, arms crossed to keep him warm.
“Ah, yes. This would have been your first time meeting with an informant,” Graves said softly. He sniffed, nose running from the cold, and shrugged a little deeper into the overwhelming heat of his coat. “It’s not as exciting as you think, Mr. Wayland. Gnarlak would have just haggled us for some cheap line about something we likely already knew. Hardly exciting detective work.”
Beside him, the boy scoffed.
“Then why do we keep him as an informant?”
“Because he might have useful information,” Graves said simply as he gave his surroundings outside the mooring house one last check. “And the possibility of good information is more valuable than the risk of losing that information just because we’re tired of Gnarlak’s bullshit.”
Jace raised his brows at him, surprised by his language. Graves’ dipped his head ever so slightly in concession.
“Apologies. I’m rather tired. Let’s call it a night, Jace. There’s always tomorrow.”
“Of course, sir.”
Graves turned to head back to their disapparition point, his mind caught on thoughts of what he would do once he got home. He’d take a Dreamless Drought, he thought pleasantly. He’d numb his ribs with a bit of mint oil and take a long, hot shower. And once he was clean and his muscles mush from the pounding water, he’d slip into his bed and—
Jace was not beside him.
He turned to look back, concerned, only to be struck right between his shoulders before he could so much as spin halfway around. He let out a shout, the sound pulled from his lips mercilessly as the ferocity of the spell shook his ribs within his chest. He couldn’t breathe, the air knocked from his lungs. He wheezed and scrabbled around, wand at the ready despite his trembling, and prepared to fire a volley of cover fire for Jace only—
Only Jace was the one that had hit him.
Gone was the baby faced boy that sought to please him. In his place was a young man, his large blue eyes a cold and deadly stare that chilled Graves to his core. He even stood differently than his junior auror had. Back straight, jaw squared. Quite like… well, quite like Graves himself, when his ribs weren’t busy trying to dissolve into dust within his chest. A painful, whistling breath escaped him.
“Not quite,” the boy said, an eerie smile on his cherub face. “But it is a name of mine, yes. Occassionally.”
Graves gripped at his ribs, his breath short from the other man’s sucker punch of a spell as before his eyes Jace’s visage melted away. He became taller – taller even than Graves – and broader too. His skin grew if possible paler, and his young golden locks became short, spikey white points standing atop his head. But all it took was one look at his eyes to know he had been a terrible, terrible mistake coming here injured.
Those haunting, mismatched eyes belonged to Gellert Grindelwald. His enemy, an international terrorist, and likely soon to be his murderer.
Graves grit his teeth. His skin itched to be gone from there, to disapparate and get help – but through the pain he knew he was too distracted to perform the delicate spell without getting splinched. Were only his ribs howling, maybe, but the spell had left his back a mottled mess of agony as well; as though he had been hit by a train rather than a simple stunning spell.
His knees felt weak and he staggered, but still he held up his wand. Across from him – pristine and perfect – Grindelwald tsked at him sympathetically.
“Poor Mr. Graves,” he purred, “No one truly looks at you, do they? Your power has blinded them to your weaknesses. No one noticed your injury. No one insisted to see you home. And after tonight, no one will notice when you’re replaced.”
Dread pooled in his belly like liquid lead. Mercy Lewis, he intended to infiltrate MACUSA in a position of power. He couldn’t let that happen.
He tried to hold his wand steadier, but it only seemed to make the shaking of his exhausted limbs worse.
“Not going to happen,” he bit out simply. Grindelwald quirked a brow at him and made a show of looking him up and down.
“You know it’s unfortunate you’re against my cause, director, because I like you. You are a just leader, respectful of your staff from the lowest rung to the highest. You instilled great practices in your men and women, and even encouraged unlikely souls like Jace to strive for excellence when no one else gave him the time of day. It doesn’t have to be this way, you know. You could join me.”
Graves snorted even though it made his ribs ache and his spine sing and said, “Join you? You truly are mad if you think I would ever join you.”
Grindelwald made a show of sighing in disappointment and said remorsefully, “C’est la vie.”
Graves had no more warning than that before the man’s knobby wand was up and directed at him, one arcing spell after another flinging at him. With one hand, Graves directed the first blow away while attempting to side step the second, but it caught the barest edge of his shoulder and sent him staggering. He needed to get on the offensive, he knew, and yet he couldn’t find the time to do much more than barely avoid Grindelwald’s attacks. Magic screamed in the empty air of the docks, pulling up huge chunks of concrete and destroying cannisters around them.
Grindelwald had no mind for secrecy. His attacks were needlessly wild and destructive – and Graves realized the man intended for his spells to do more damage to the world around them than to Graves himself. He wanted to leave a scene behind. He wanted the No-Majs to know.
Graves had to risk it, he had to disapparate. He wouldn’t make any true distance that would get him to safety, but he could make it a few feet – and that would have to be enough.
He disappeared behind the light of another arcing spell before it could hit him and reappeared – breathless but whole – behind Grindelwald a moment later. He gathered his power as fiercely as he could and let lose a stunning spell that sent Grindelwald flying across the jagged pavement he had torn asunder and into a heap by the dock and the water.
Graves heaved a breath he couldn’t catch and moved to stand over his foe, to wrap him in chains and call for help, but as he stepped forward darkness began to creep around the edges of his vision.
“No,” he murmured, as though by words alone he could convince himself that he was fine. “No, no, no, not now.”
He took another two or three steps before his knees turned to jelly and bit the concrete. He cried out and he cursed raggedly beneath his breath, then finally looked up to find his enemy gone. He turned quickly to try and spot him and the shadows in his peripherals got worse. He wanted to vomit. He wanted to sleep.
He heard the sound of someone coming up beside him on his other side too late. He turned right into a spell that felt more like a punch to the face than anything constructive or purposeful. He shouted wetly, blood already slicking his lip, and knew immediately his nose was most certainly broken.
He tried to scrabble to his feet but Grindelwald shoved him back down to his knees mercilessly. When Graves looked up, the man looked none the worse for wear. It seemed entirely unfair. Panic began to build inside his chest.
“W-why are you doing this?” Graves gasped wetly, his teeth shiny with blood from his broken nose. “Do you really hate the No-Majs so much that you would jeopardize the safety of your own kind?!”
Grindelwald towered over him, a menacing shadow with a shock of white hair and a shining pearly slit of a smile. He clucked his tongue and bent down at the hips so that he was invading the director’s space. With quick fingers, he snatched Graves’ chin between his thumb and forefinger, and tipped his gaze up to lock with his own unnatural stare.
“Oh my dear director,” he cooed, “Witches and wizards are not my kin. It is, however, because of them that my kind cannot enjoy this world as we should. We remain holed up in dark caves and murky waters and sinister alcoves, unable to journey back to our motherlands – filled with rich flora and soft sands and sunlight – because your kind is too afraid to put humans in their place. Too afraid of ‘exposure’.”
Graves blinked, his teeth-bared sneer melting into cautious confusion. One of his pupils wasn’t contracting anymore, concussed. Blood oozed sluggishly from his nose, his temple, his hair line.
“What do you mean, witches and wizards aren’t your kin?”
There was a tremble to his voice that Graves tried his best to hide, but Grindelwald caught it all the same. The madman smiled and when he did, two little canines became readily visible in his mouth. Graves flinched.
“Rather presumptuous of you to assume your greatest enemy was a wizard, Mr. Graves. Don’t you think?” He chuckled. “I expected more from MACUSA’s greatest.”
“What are you?”
“It’s a little too late for that information to help you now, don’t you think?”
Graves’ mouth pressed into a firm, resigned line. He jerked his chin free of Grindelwald’s grasp and squared his jaw a little tighter, tipped his chin a little higher, and glared.
“Do your worst.”
He braced himself, jaw so tight it hurt, but forced himself not to close his eyes. He’d meet his end head on, he told himself. If nothing else, he would do that much.
Seconds ticked by and yet, nothing happened.
Grindelwald felt a little pang in his heart that he had not felt in years. His blood quickened in his veins, magic flush and excited just below his skin. He sucked in a quick, harsh breath and then let it out in a loud, slow, stuttering laugh – surprised, amused, enticed.
“You are quite fascinating for a wizard, Percival,” Grindelwald smiled. He lifted his hand first to the man’s neck, his grip loose and suggestive as he thumbed the director’s fragile Adam’s Apple, and waited for a reaction. When no begging came, no crumpled expression, no fear, he then lifted that hand higher and brushed his thumb over the painful swelling of Graves’ broken nose and set it back to its proper place with magic. He smiled when he caught the noticeable surprise on Graves’ face. A startled blink and a soft, relieved sigh to finally have the throbbing in his face ebb away.
Grindelwald didn’t give him another moment to ponder it. He then brought his hand to cover the man’s eyes and compelled him to sleep with a soft, whispered spell. Exhausted as Graves was, the effect was instantaneous. He caught the director by the shoulders just before he could crumple completely to the ground and gently scooped him into his arms. He looked down fondly at the face of his unconscious potential mate-to-be and smiled.
“Oh what fun you’ve turned out to be, Percy dear. Oh what fun indeed.”
Chapter 2: No Going Back
Graves woke somewhere far away from New York, that much was clear right away. In the night’s air a chill had crept over him, but he could tell from the fine powder of the sand that he was somewhere warm and tropical, the sun having absorbed into it all day and only just beginning to fade.
His eyes fluttered – disoriented – as he was lifted momentarily in bodily jerks, the sound of popping buttons confusing him as they pattered uselessly to the sand around him. He was eased out of his shirt, then two hands ran down the length of him from his shoulders, over his tight chest, down the flat span of his stomach to stop at the hem of his trousers. He opened his eyes and took in the visage of his captor haloed in the sway of glittering palms. Palms unlike he had ever seen, their leaves pale like silver and glowing like stars in the darkness.
Above him, Grindelwald smiled kindly.
“Finally awake, sweetheart?”
Something fuzzy worsened in his head, making his mind feel stuffed with cotton and the pressure behind his eyes suffocating. He closed them and that felt a little better. Grindelwald chuckled softly, murmuring a soft ‘sleepy boy’ beneath his breath like a song. His shoes and socks were removed and his chill got sharper. His pants were jerked from his hips in rough pulls and thrown to join his shoes. Finally, his underwear joined them and he was naked in the sand, skin tan in contrast to the snow white of the particles that covered him.
Gentle hands cupped his cock and held it from his body as though weighing it. Distantly he caught Grindelwald murmur, “So big, and yet you could still be viable…”
What came next was stranger still, making the fog in his head flutter alarmingly as something screamed deafly to be heard. Something cold and long and soggy was stuck to his skin in a strip, then another and another, one after the other in a strange crosshatch. He opened his eyes with a wince and a little frown, and leaned up muzzily onto his elbows to look down to his hips where Grindelwald was sticking long stripes of seaweed onto him, murmuring unintelligibly all the while. Words that slid through Graves’ mind like oil, too slick to catch but leaving runny trails in his mind as they passed by.
Grindelwald clucked his tongue disapprovingly and eased him down by the shoulders until he was prone once again, a whisper of magic making him drowsy once more, too heavy to move. He groaned, confused and exhausted, as hands lifted his legs in a rhythm of up and down, up and down – winding his lower body in seaweed and other marine plant life until his legs were bound together from hips to ankles like a worm.
“It’s almost over, love,” the man leaned over and said into his hair, lips murmuring into his scalp. Something wasn’t right. This wasn’t right. What wasn’t right? The fog began to drift and thin.
He was lifted into a pair of strong arms, sand falling from his back in a tinkle of dust that sparkled in the moonlight. He heard the sound of feet walking through water. Graves blinked and looked down. Grindelwald was walking them slowly, deliberately into the water. That was strange, he thought. But it would feel so good. His skin itched for it. Ached to be cooled of his fever. To be slick and chill and free. He let one hand droop down, eager for the water’s embrace, and Grindelwald chuckled.
“Such a good boy for me,” he praised. “So ready, so perfect. I knew you would be. We were made for each other, you and I. Destined to be mates.”
Graves moaned as his head suddenly throbbed. Mates… Mates with Grindelwald. Mates with… his enemy. The word clicked in his mind and he gasped like suddenly immerging from the water after staying down for too long. The docks, Jace, Grindelwald – he had been kidnapped and – wildly he reached for his magic, one hand out to blast Grindelwald away from him while he could still fall in shallow water and claw his way safely back to shore without drowning.
It didn’t come. Instead of his magic appearing as he envisioned, he felt it siphon from his palms and travel his veins down to the seaweed that embalmed him, absorbing it and warming around his flesh. His legs began to tingle, as well as his crotch, sending his heart into a fitful blaze.
“Ah, you’re back,” Grindelwald said with a smirk that bled into the tone of his words, “Just in time.”
“What are you—Are you fucking crazy?!” The words exploded from his mouth in a gush as surprisingly temperate water – not warm, but pleasantly cool, pleasantly refreshing – greeted first his ankles, then up his calves and the seat of his ass. He tried to kick out, but the seaweed was stronger than he could have imagined, so strong that it didn’t even stretch when he tried to spread his legs to break it. He pressed at Grindelwald with his hands, but the man only chuckled and continued to march them into the sparkling waters of the lagoon.
“Grindelwald,” he gasped as the water reached his navel, unable to hold back the desperation that was beginning to claw its way up his throat. He couldn’t swim like this, he’d drown, holy fuck Grindelwald was going to drown him.
His guts churned as death approached for a second time that night and he felt fear loosen his throat for a plea, for begging, but the words fell to dust in his mouth as the water turned Grindelwald’s clothing to specks of stars, hovering above the pool of water and lighting the way to its depths in the middle of the lagoon.
“Don’t worry, darling, I’ve got you,” Grindelwald said, utterly unphased. “You wizards, you think you’re the most powerful generation this world has yet to spit from its womb; but time has made you deaf to the old stories and that only makes you blind. What use is all that power to a blind mind? Cut off from the Old Ways, throwing temper tantrums with your spells and foci like children. But you… You’re the closest I’ve seen to the men from the old times and the Old Ways. The most viable wizard I’ve seen in a long, long time.”
Viable. That word again.
“What the fuck are you talking about?!”
Grindelwald ignored him. The water embraced Graves to his shoulders, his neck. His breath accelerated. Fear seized his lungs like a vice and he craned his neck to stay above the water. He was going to drown—
Grindelwald took advantage of his open-mouthed plea for air, surging down to plunder him. He sucked Graves’ bottom lip between his teeth and he bit him, sharp canines piercing soft flesh. Graves shoved at his shoulders and chest, and surprisingly Grindelwald released his lip, his smile bloody and pleased. Graves touched his swelling lip, red smearing across his fingertips, and tongued the puncture marks – deep and only on the inside of his lip. The punctures tasted strange; tangy like copper, yes, but something else. Salt water, maybe. Sharp and earthy.
His eyes were positively owlish when he looked up at Grindelwald, he knew, but it was hard to feel embarrassed when he was so damn confused, when his heart was hammering so hard, when his mouth was so full of that taste, quickly turning sweet. The more he licked and worried at it, the more the tingling in his crotch quickened and increased, spreading up his belly, enveloping him in a most concerning way.
“What—?” He managed to babble before one of Grindelwald’s hand came up to frame his jaw, searching for something so intensely it stole Graves’ focus for just a moment, before he swept one thumb to trace his lower lip and said, “You are going to be beautiful.”
Then Grindelwald let him go.
He managed one horrified yelp before the water embraced him.
Grindelwald’s image warped above him from beneath the water, his skin suddenly teal and white, glimmering strangely. He watched as Graves sank, hands thrashing to give him the push he needed to rise, but his bound legs anchored him down. He screamed and wriggled, his magic lashing out wildly and with abandon, but the seaweed ate everything up and the tingling just grew. It accumulated in his crotch and his waist, gathering in his chest, the sides of his neck, all down his legs and feet. The water pressed in on him unnaturally, and even though he had only sank a few feet it weighed on him as though it were trying to compress him, change his very shape. His scalp began to itch, his bones ached. Finally he screamed and the water came to claim him, and he welcomed it if it meant the endless pain would finally, finally end.
He awaited death; surely he could escape it no longer. A shadow passed in the water, quick like a dart. The edges of his vision began to grow black, the taste of the sea so fierce in his mouth and then there were lips on his, breathing what felt like heavy, glossy air back into his lungs. He latched onto the owner of those lips, nails digging in like a knife through butter as he clutched tight to them, breathing them in. When their lips parted, he surged forward for more, terrified he’d die, he’ drown, he’d – but the water ran through his lungs like fresh meadow air and he breathed.
He breathed underwater.
When next he opened his eyes, the world was as clear as it would have been on land, every inch of the depths of the lagoon painfully visible to him. It was unnatural, infeasible, and yet his heart still pounded at the wonder of it all. It was terrifying and yet amazing.
He was a good number of feet down now, nearly at the bottom. Hands grabbed his jaw and turned him, filling his vision with another man’s face – Grindelwald’s face – only it was different now. His skin was flecked with pearly white scales that framed the very edges of his cheeks and brows, the length of his neck, his ribs and followed a trail down to –
Graves’ mind froze as he took in Grindelwald’s tail, just as pearly as the rest of him like a shroud of death, his fins gossamer and floating beautifully. He was broad like this, muscled in ways Graves hadn’t anticipated, and at his neck something fluttered. Gills, Graves realized. The man had gills.
“Mermaid,” Graves gasped dumbly. Something swirled in front of his eyes, making him jerk back, but those hands held his face close, stopping him from pulling away.
“No,” Grindelwald said, eyes suddenly so hungry. “Merman is the word you’re looking for. I’m not the Mermaid, sweetheart, you are.”
Then that hand raised and grabbed a swirl of that inky blackness that had swayed into his vision, stretching it between them until finally Graves felt a slight pull on his scalp. It was his hair, he realized, only longer than it had ever been, curling around him like a halo as it danced in the water. Not a hint of grey in it either.
“So beautiful,” Grindelwald said, soft and slow like he was looking at a miracle. “Do you know how our kind is made, Percival?”
Percival. As though they were intimate; anything other than enemies. Our kind, like he was one of them – a creature of the sea. Beneath the seaweed his skin itched and ached.
“They can be born, yes, but the process is a long one. We’re hunted now. Relentlessly. Our mates cannot rest in the cool waters of our mating lagoons to grow fat and bear life because they cannot make the swim to them before they’re picked off. Babes are few and far between, our grounds destroyed by humans and development, and we can’t fight back because of these infernal statues of secrecy. We are near extinction, and yet the magical world turns a blind eye to us so they can remain comfortable. But there are other ways to create life. The wizards and witches that remember the Old Ways, the ones powerful enough to survive, they can be changed. Like you’ve been changed. And now we are one powerful Mer-creature closer to beating extinction.”
No, he thought, eyes wide and tears eaten by the lagoon as he shook his head in the frame of those hands. No, no, no.
He shoved the man away and reeled, disoriented, as his legs kicked awkwardly. Each thrash loosened the wrappings that kept him prisoner though, so he kicked harder, feeling them peel away like the petals of a flower on a sudden, crisp fall morning. The more he kicked the more the itching and the aching stopped, and he sucked in a sigh of relief as they faded away and finally he could move, he could swim.
But it felt wrong. He couldn’t separate his legs, everything beneath his hips felt alien and cumbersome. He flailed in the water frustratedly before finally twisting to look at his legs, convinced there was still some seaweed trapping him tight, only to find all of the seaweed gone. Gone like his legs. Instead everything from his hips down was a solitary, powerful column of muscles that tapered down to a single thin joint and bloomed into a set of large, silky looking fins. He was covered in scales, rich like blazing emeralds and tipped in black, contrasting strikingly against the paleness of his belly where scales turned to skin once more. His forearms where flecked with it; his belly, his ribs, his chest. And he was smooth. Genderless looking.
His prick was gone.
“The fuck…” he wheezed, hands shaking as he moved them over the flatness of his scales and new appendage. “What the fuck!”
Grindelwald swam up to and swatted his hands away, then grabbed his slender hip by one large hand and began to run the fingers of his other over a select group of scales, voice gentle as he reassured him.
“Ssh, ssh, ssh, you’re all right. It’s here,” he purred, and Graves could only suck in a sharp breath as his scales fluttered, nerves alight in a manner he couldn’t even comprehend but knew was arousing. Grindelwald pet that place again and again, the tip of one nail parting a few and slowly creating a seam Graves hadn’t even realized was there. From this seam his flesh began to part and slowly, ever so slowly, a small protrusion began to appear – pink, tender and tapered.
And small. At least half the size he remembered it.
“Ah,” Grindelwald said, “Not quite done yet are we?”
Graves had no more warning than that. Grindelwald began to stroke it, cooing over how perfect it was soon going to be, and Graves felt his body melt into the man’s hold. His eyes rolled and a strange, melodic purring began to emit from his throat, vibrating his gills. He tried to control himself, to suck in a breath to tell him to stop, to let him think, but he could barely hold onto Grindelwald’s forearm and shoulder to brace himself, let alone string together coherent sentences. Below his prick he felt something swell and heat, pleased by the attention. He figured it was his balls.
And in Grindelwald’s hand Graves’ cock slowly but surely began to shrink. At first Graves thought the thing was merely retracting back into his body. With every throb Grindelwald’s fingers coaxed from the little organ, it seemed to swell before shrinking to a length shorter than before, over and over. Before Graves’ eyes he lost another inch, then another – helpless as Grindelwald stroked his size away.
“Nna-aah, nn, nn, nno-ooh-aaah, ah, ah,”
“You’re still intact, mostly,” Grindelwald said, focused on his task, eyes fixed on Graves’ moistening slit as something thicker than water began to ooze from the seam that continued beneath the man’s little dick, a hole slowly beginning to appear from behind it. “Although this little thing is going to be much too pretty to call a prick, really. It’s more similar to a woman’s clitoris than the heft of a real man’s cock. Not to worry, though, you’ll match this cute little thing soon enough.”
The thought was terrifying and yet Graves couldn’t resist the magic of Grindelwald’s fingers. The shrinking didn’t stop until he came, spurting a little cloud of clear liquid, and he tried not to think about the fact that the man had needed little more than a thumb and index finger to coax Graves’s pathetic excuse for a cock to orgasm. It was barely larger than a grown man’s thumb now, and even though he had come it appeared to refuse to soften – instead bobbing and twitching in post orgasmic bliss against Graves’ tail.
“What the… What the fuck did you do to me?” He asked, eyes still closed as he reeled from the strength of his orgasm. It hadn’t been like ejaculating as a man had been. It had been a full body pull that sent shivers over his entire being, making his nipples perk and stand hard on his chest, and all of his skin – and scales – tingle. Lost as he was in the sensation, still butter soft in Grindelwald’s arms, he missed it the moment the merman slipped a thick thumb in something he couldn’t even fathom.
He had never felt anything like it. It wasn’t his anus, he knew, and yet there was a new, moist cavity beneath his ball-less prick that Grindelwald had slid into. He mewled before he could shout, his throat lax and prone to moaning after so much pleasure. It felt…
Grindelwald’s thumb and the girth of his middle knuckle stretched him pleasantly, his opening so slick and swollen from the prior attention to his prick. Grindelwald stroked his tender insides before pulling out and inserting two fingers instead, searching. Graves gasped, heart thrumming, overwhelmed by all these changes and the fast pace of their revelations that he couldn’t keep up with.
Grindelwald pressed something inside him and finally he screamed, head thrown back and throat taut as he clutched tighter to the merman, drawing blood.
“Perfection,” Grindelwald purred, voice so dark and so hungry – barely reminiscent of the man on the beach. “I’ve got you, darling, you’re almost done.”
The fingers were removed and his slit ached from the loss, that moist seam drooling helplessly into the water, trying to entice something, anything back in. He felt empty. He whined.
Something long and tapered and hot pressed against him, two hands holding his hips firmly in place and then it was sliding in, filling him in one long fluid push. He yowled, the end of his scream melting into a moan as finally the aching dissipated, and pleasure bloomed in him once more. His tiny dick shivered between two scaled bellies as Grindelwald began to thrust, twirling them in lazy circles as he kissed Graves’ neck, his shoulders, the edges of his hairless and softening jaw.
Graves’ eyes rolled, and while something in the back of his mind howled that he needed to pay attention and escape, he couldn’t focus past the relentless rhythm of Grindelwald’s pounding dick in his sopping cunt. Hands moved from his hips – hot and swollen – and brushed his nipples instead, tweaking and pulling and playing until they felt hot and swollen too. Graves mewled, the sounds swallowed by a hungry mouth when Grindelwald quickly kissed him, tongue slipping between lust slackened lips and conquering.
Grindelwald pet the seam of skin stretched around the girth of his invading prick, stroked it while it appeared to swell even more where they met. Graves keened as that stretch moved further and further into him, struggling at his surreal entrance until finally it popped in, making his cock dribble feebly. He could feel it traveling up and into his new insides, passing up and up and up. He felt a little bloated.
Another followed just behind it, stretching him just as taut before sliding in. Grindelwald pet his neck and his hair. He pressed kisses into his neck and when next he tweaked his nipples Graves felt the flesh of his chest move as though there was some give to it. He moaned, confused, aroused.
The third swell entered a little easier. He could feel his stomach begin to press against Grindelwald’s flat abdominals.
“You’re going to be so fat with my eggs,” Grindelwald said. “You’re going to save us.”
His hips ached. His belly felt so full and while it felt mind-blowing entering, the next egg made him feel too tight, fit to burst. He sobbed into an open-mouthed kiss as Grindelwald’s words registered. Eggs. He was impregnating him.
Finally no more eggs passed through him, and as though Grindelwald knew there would be no more, he began to thrust – hard and heavy. Graves could feel a strange weight on his chest, shifting with each thrust. He tried to look down but Grindelwald slipped in for another kiss, his tongue running over Graves’ sharp new canines. He whined when Grindelwald grabbed his chest and pressed that weight into him, and he knew he was soft there. Without looking, he knew he was suddenly soft there.
“Perfect,” Grindelwald gasped into Graves’ mouth, shoved forward twice more, and then warmth was blooming inside Graves, filling him even more. It came like a slow and steady faucet, and he kept waiting for it to end, but it seemed endless. His bloat worsened, fat against Grindelwald’s slim belly. Fingers took him by his tiny cock and fondled him and he clenched, his whole body seizing as that pushed him over the edge. He could feel it as his insides milked Grindelwald’s dick, urging more of the merman’s seed deeper, and he sobbed.
Grindelwald only pulled out once it had stopped, but nothing leaked out with the exit of his dick. He brushed a large thumb over Graves’ sopping, gaping entrance and purred as it shrank again beneath his touch, taking his dick with it, the scales sealing and trapping in his eggs and sperm. Leaving him fat and – and – and –
He sobbed again, hands shaking as he reached down for his pudgy belly. He looked down and his face contorted as he found his view obscured by two modest breasts, just enough for a handful. Grindelwald cupped one and brushed a thumb over its still erect nipple, smiling when Graves moaned despite himself and shivered.
“Lovely,” he purred, “Marvelous, perfect. Such a good mama.”
“Get them out,” Graves whispered, eyes wet. “Change me back.”
“No, pretty mama,” Grindelwald said as he moved both hands up to cup a slender jaw and pet back tears from long, sooty black lashes framed with flecks of beautiful green scales. “There is no going back.”
He guided Graves' hand back onto his heavy breast and squeezed his hand around it while taking the other to Graves’ belly, making him feel the life beginning to sow there.
“There is no going back.”
