Mermaid Sire

The salty sea breeze whipped through Dr. Lang's hair as he and Alex stood on the deck of their small fishing boat. The sun was just beginning to dip below the horizon, casting a warm orange glow over the water. "Dad, do you think we'll catch anything today?" Alex asked, peering into the depths below. Dr. Lang chuckled, adjusting his fishing rod. "I have a good feeling about today, Alex. The sea has a way of surprising us."

As they waited, a figure emerged from the water, glistening in the fading light. It was a beautiful mermaid, her long hair floating around her as she swam gracefully towards their boat. "Dad, look!" Alex exclaimed, pointing at the mermaid. Dr. Lang's eyes widened in amazement. "We must catch her. She could be the key to unlocking so many mysteries of the ocean." With practiced precision, Dr. Lang maneuvered the net and successfully trapped the mermaid, much to her dismay. The mermaid let out a haunting melody, her voice filled with sadness and longing. "We've done it, Alex! This is a momentous discovery," Dr. Lang proclaimed, his excitement palpable. As they headed back to the research center, the mermaid's haunting cries echoed in the air, tugging at Alex's heart. Back at the research center, Dr. Lang and his team worked tirelessly to study the mermaid, unlocking the secrets of her underwater world.

One night, as Dr. Lang and Alex were sitting by the water's edge, a deep, resonant voice filled the air. "Lang! You have something that belongs to me." It was Neptun, the ancient god of the sea, his imposing figure rising from the depths. "Neptun, what brings you here?"

Dr. Lang asked, his voice trembling slightly. "That mermaid is under my protection. You have no right to keep her here," Neptun thundered, his eyes flashing with anger. "We are merely studying her for the betterment of science," Dr. Lang reasoned, trying to calm the god. "Your arrogance knows no bounds, mortal. You have defied me, and now you must face the consequences," Neptun declared. Before Dr. Lang could react, Neptun reached out and snatched Alex, pulling him into the watery depths. "Dad! Help!" Alex's muffled cries filled the air as he disappeared beneath the waves. "Alex!" Dr. Lang shouted, his heart pounding in his chest.

Neptun's laughter echoed across the water. "Your son is now in my domain. Unless you return what is mine, he will remain with me forever." Desperate and filled with fear, Dr. Lang agreed to Neptun's demands, releasing the mermaid back into the sea. Neptun's eyes glinted with triumph as he released Alex, but something happened. Alex grew scales on his legs and his legs grew together. He screamed until he had fully transformed into a young, glistening merman.

Dr Lang's jaw dropped. "Alex, what... what's happening?" Alex looked down at himself, marveling at his new form. "Dad, I feel... alive, powerful, and... different." His words spilled out with a mix of confusion and excitement. Neptune's booming laughter filled the air. "It's mating season, young one. And you, at eighteen, are at the peak of your mating urge." Dr Lang's mind reeled. "Mating urge? What are you talking about?" Neptune's eyes twinkled with mischief. "My dear scientist, your son will soon have only one thing on his mind. Once he's fulfilled his purpose during mating season, he will return to his human form and to you." Dr Lang struggled to comprehend. "But... but this is absurd!" Neptune's laughter echoed across the water. "Absurd, maybe. But it is nature's way. And your son will serve his role splendidly. He will become an exceptional specimen, a prime candidate for mating."

As if on cue, a group of young mermaids appeared, their sleek bodies gliding through the water with purpose. Alex's eyes glazed over with an intense desire, his instincts taking over as he joined the group without hesitation. "Alex, come back!" Dr. Lang called out, his voice filled with anguish. But Alex was lost in the throes of his newfound instincts, his consciousness consumed by the need to mate. About fifteen mermaids surrounded Alex in a beautiful bay and began kissing and caressing him. Alex got more and more aroused and his cock throbbed until it emerged from his scales in a fully erect state. A mermaid asked Alex:" Are you ready to mate?" Alex nodded and she called out to the other mermaids:" He is ready. Let's make him breeding stock." The mermaids touched him all over his body and stroked his cock. They kissed him and licked his neck. He was lost in a sea of sensations and couldn't think straight. Finally one of the mermaids mounted him and rode him hard. He felt her pussy contracting around him and he couldn't hold back any longer. He exploded inside her and filled her with his cum. Immediately another mermaid took her place and rode Alex' cock. He mated with each of the mermaids and drifted afterwards completely exhausted in the wide sea. Neptun watched the scene with enthusiasm and said to Alex:" Your instincts and your stamina are strong, they will turn you into a mere breeding stud in no time. "Alex whispered with an exhausted voice and a smile on his lips:" Yeah, breeding stud!"

Time seemed to stretch endlessly and Dr Lang's heart was heavy with guilt and sorrow. Eventually, as the mating season passed, a familiar figure emerged from the waves, but it was not the timid, bookish Alex he knew. Instead, a striking, confident athlete stood before him, resembling a Greek god brought to life.

Alex spoke, his voice laced with an otherworldly resonance. Neptun smiled at Dr. Lang, his gaze piercing. "Your son has served his purpose well. He is truly a specimen of great potential." Alex turned to his father, a sense of purpose burning in his eyes. "I have made arrangements with Neptun. I will return to the sea during mating season next year." Dr. Lang's heart sank at the thought of seeing his son again guided by his instinct like a mere animal.

"Alex, you don't have to do this. You're not just some breeding stock." Alex's voice was resolute. "I am Neptun's stud. I will mate with whatever he brings to me." Neptun fixed Dr. Lang with a cold gaze, his hand reaching out to Alex' balls possessively. "That belongs to me now," Neptun declared, his voice like crashing waves. Alex smiled proudly and said: "I couldn't imagine a greater honor than you claim my seed - it is all yours." Dr. Lang felt a surge of helplessness and fear as he realized the extent of Neptun's control over his son. Neptun gave Dr Lang a handful of pearls and added cold:" Send your son to the best universities money can buy, and make sure that he gets good grades. If you fail I will take him away and train him myself. I have big plans for my priced mating stud!"

Whump Prompt 97

Write something inspired by this concept:

A mermaid gets obsessed with a human and uses dark magic to trick him into becoming a merperson too. He has no choice but to follow her into the depths of the ocean.

The problem is, changing into a merman is horribly uncomfortable and traumatizing. As he adjusts to his captivity in an underwater prison, light and air feel like they're a lifetime away.

Merman TF (rubber, transformation, WIP)

This short fiction (~1,600 words) was originally written as a blurb which I expanded. I'm revising it again to make it longer and more story-like, but I'm tired and procrastinating and it may not be done for months, so I'll post this second draft as-is.

Intent on checking his nets, a poor and lonely old fisherman walks along the shore at daybreak, creeping along the cold sand and stray bits of seaweed through the chill wind. At the beach's rocky boundary, he finds a pair of golden bracelets lying in a tide pool, mysteriously abandoned. They look intricate, expensive. He could pawn them, or return them to their owner for a reward. Overcome with curiosity, he picks them up. They glow, then jerk, and fling themselves onto his wrists of their own accord, tightening fearfully. Immediately a viscous, coral-red tar pours forth from the bracelets, in thick strands that lengthen and wrap themselves around the fisherman's arms.

In a panic he tries to pry the bracelets off his wrists, but they are clamped tight, and prove impossible to remove. His hands, now coral-red and rubberlike in texture, appear larger, stronger. The rubbery tar spreads up his arms in hungry webs, and tentacles shoot out and latch onto his torso like grabbing hands. They lengthen and twine around him possessively, squeezing and groping around his emaciated body through his threadbare clothes. Against his arms the first strands shorten and grow taut, pulling his arms together and then binding them against his chest with a slick plop, and the cloying slime swells in spurts and waves, thickening around him layer by layer.

Immediately the fisherman's thoughts are of getting help, and be begins to run back down the beach toward town. As they slither under his clothes and wrap around his chest, the red vines extend downward and wind themselves around his legs, growing thicker and stronger as he gallops like a horse, fighting to free his arms of their slick bondage as he goes. Stealthily the tarry vines around his legs thread together, knot and grow taut, and before he's gotten fifty feet, just as the fisherman manages to break the vacuum seal around his arms, his legs are bound up and he falls forward onto the sandy beach, rendered immobile.

He catches himself, with some relief, then his arms are seized again and yanked behind him by a hungry mass of ropey tentacles that bind him by his wrists to his ankles, hog-tying him neatly. He calls for help, his voice hoarse and quiet from frequent disuse in life, but the cunning tar creeps up his neck and stretches a slick gag across his mouth, muffling him. The slime smells like sea-salt, and sweat, fragrant and masculine. Bitterly he fights against his cunning restraints, angrily bucking and grunting, but the rubbery tar ripples and bubbles around his body into the beginnings of a cocoon. And still the goo pours from his demonic bracelets, unabating, spewing syrupy hands that spread across him in webbed striations, clawing their their way over his feeble form.

The goo around his body surges and swells, slowly growing him into a shapeless mass. When his legs are completely encased the restraints behind him snap, and the fisherman heaves and rolls himself onto his back with a grunt. He fights with a renewed fervor against the slippery evil encasing him. He rakes at the rubbery gelatin coating his legs and claws furrows into the malleable, pulsating mass. His arms, now thickened with forming muscles bigger than he has ever witnessed, are powerful. But the virile bracelets spread far more of the tar along his extremities than he can tear away, spewing heavy loads of living crimson that fill in the claw-marks while growing his legs longer.

More tentacles sprout from his manacled wrists and latch onto and encircle his waist with increasing girth. He yanks at the ravenous ropes encircling him and they stretch taut, then grow instead around his arms and wrists, tangling them and swelling them further. They clamp around his meager muscles until, in pain, he's forced to release his grip on the goo enveloping him. The vines pull his arms against his sides, leaving him lurching and armless as a snake. He wriggles and cranes his necks to look down at himself, with difficulty as tendrils climb past his nape and dig into his pressure points. He resembles a dozen spiderwebs overlaid each other, hundreds of gooey strands upon strands all stretching and writhing and circling around him, clinging and swelling and merging into an increasingly shapeless cocoon intent on devouring him whole. And still the tar pours forth from the bracelets, unabating.

The gag that stifles him sends forth feelers, thin tendrils that part his lips and climb into his mouth. The scents of salt and masculine musk are overpowering to the his nostrils and tongue. The demonic tar presses down at him from every which way as he wriggles inside it, invading his pores and binding to his skin. He can't feel his clothes anymore, the fabric eaten away by the viscous tar. Gooey ropes shoot from his arms and torso onto his legs, the pulsating vines transferring mass to lengthen the growing stump of his legs even as more slime flows from the bracelets onto his upper body. His bound-up legs grow and stretch into what seems a heavy tail that swells and lengthens, unfurling to reach ten feet, fifteen feet after a minute of steady work. The fisherman wriggles impotently in his crimson bondage as he grows to gigantic proportions.

As the eel's tail reaches twenty feet, a long fin unfurls along both of its sides like a folding fan, a wide, strong membrane that conjoins at the tail and extends its length by another three feet. Finished expanding, the goo stops its travelling and turns its attention inward. The taut webs of ropes stop their serpentine writhing and begin knotting and lacing, entwining and wrapping. Slowly they begin to settle in place, and their surfaces flatten, smooth and congeal into a shiny, rubbery skin on the body. Inside the congealing, the wriggling tar separates into heavy cords of striated muscle, rippling and knotting and swelling with strength. Hungry for bones to support them, the pulsating fibres bear down on the fisherman, grabbing and digging into his naked body as they lengthen and thicken. And finally the last of the goo crawls over the fisherman's head, in hungry hands, lacing over his face and shutting him in darkness.

Hundreds of muscles fill the empty tail, diagonal and paired, working in tandem, and more of the tar congeals into strong ribs and vertebrae. The bulging muscles strain against the rubbery red skin, standing in stark definition as the skin pulls taut around them. The long belly turns white with speckled borders, the tailfin turns the beautiful bright green of sea grass. As the goo swallows his face a new face is formed over him, the hauntingly beautiful mask of a Sea Prince, red with a splatter of black around sapphire-blue eyes. Strands of white hair sprout from his scalp and grow long. Spiraling dark horns grow up from his forehead, and pain shoots through him as they anchor themselves in his skull. Pale claws grow from the tips of his fingers.

The fisherman cannot breathe, the rubber is suffocating him. With newly free arms he digs in his talons, and yanks at the slick rubber that has encased his face. He tears through the skin and pulls it away. The mask tears apart, and his face tastes fresh air. The tendrils in his mouth stretch and cling to his gums. But his arms grow heavy, and he's unable to hold it. The mask snaps back, and knots over his face. Again he digs into the rubber and yanks at it, but it stretches less each time he tugs, each time gripping his face more tightly still. He twists and pulls at the flesh-prison around him, but with every passing moment the still-developing system of muscles around him grows stronger and denser, and soon he is unable to move his limbs or body, helpless to its power. Instead the rubber skin begins controlling his body like a puppet, moving his limbs for him without his volition.

The muscles cement themselves to his body. Tentacles invade his mouth, his ass, filling his orifices with pulsing thickness. Air-tubes insert themselves into his nostrils, supplying him with air. The eyes behind the tight mask around his face pulse with hypnotic blue rings, as between the fisherman's legs the merman's twin procreative shafts form and begin throbbing with need, assaulting the fisherman with waves of pleasure. Against his will, his struggles weaken, hypnotized and subservient to the Sea Prince's will. He feels the mask of the great eel grow taut on his face as it smirks in diabolical satisfaction.

The merman reborn tests his new body idly, coiling and uncoiling his great length and feeling his muscles flex with ease. He is powerful, he knows, and he relishes his great strength. Satisfied, he gives into the waves of lust. He looks at his twin shafts, then rolls onto his stomach and starts grinding against the sand, humping and humping for friction. The tension in his gut builds until he climaxes and releases a vast, pearlescent puddle of seed. He coils himself, then uncoils in a flash, and springs himself forward into the ocean. In the shallows, he waits, invisible, unmoving. On the sand, his seed lies sticky and potent, alive with magic and ready to grab the next passerby and transform them into the Sea Prince's mate.

Becoming human 🧜‍♀️

Does the shrinking hurt, like being squeezed and split in half? Or is it like being hugged all over?

I don’t draw usually shrinking because it freaks me out! What do y’all think??

Dark Blue Moon and the Suffering Sun Part 7

reblog and comment plz <3 i read every one of them and love them all

also here's the masterpost

Damian knew Phantom used echolocation to locate this ravine in the first place, but the question was whether Damian could try the same thing. Damian hugged the walls of the cliff face, keeping his body flush against the surface, and lurking around corners and behind obstacles. The coast was clear.

Clearing his throat, he let out a high-pitched click, projecting it as far as his voice could carry. Immediately, his sensitive ears picked up the echoes coming back in layers. While the sound he sent was singular, the echoes came back in staggered waves, with layers of different pitches and tones and brief silent spells over the course of a millisecond.

This echolocation was useless!

Damian weighed his options. He could approach the surface, but there was no telling if Skulker had a vessel nearby where he could lick his wounds. The worst thing he could do was just hand himself on a silver platter to the creep. On the other hand, he doubted a flashlight would be very useful at the very depths of the ocean.

He still had to try.

Damian’s backside tingled with a light pressure, a feeling he’d come to associate with his lateral line. He armed the wrist ray on his left hand, and grabbed the Anti-Creep Stick with the other. Scanning the ravine revealed no other sirens or fish, but a slight stirring caught his eye.

Damian squinted at the crevice on the opposite side of the bark, not quite sure of what he was supposed to be looking at, until his nose caught the smell. There was definitely something there, but it didn’t smell like another siren the way Phantom and the teenage girls did.

An octopus then?

Octopodes were intelligent creatures, beautiful examples of the ocean’s biodiversity.

But Phantom needed sustenance, and he couldn’t afford for Damian to be picky. However, he put away the bat regardless. He wasn’t so cruel as to bash its head in to death. No, he would make it quick.

Damian unsheathed his claws, and coiled up his tail. Hopefully it wasn’t one of the poisonous varieties. He truly did not want to test Phantom’s immunities at the moment. Like a tiger waiting to leap, Damian kept his body still, and scrutinised the rock for the slightest deviation in colour…

There! Damian pounced. The octopus’s colour returned to its natural yellow pallor. His hands wrapped around its bulbous head. Score! Now to kill it. Sorry octopus, your sacrifice will not be in vain.

However, the mollusk was not about to give up without a fight. Suckered tentacles slapped at Damian’s face. The slimy skin of its head allowed it to slip out of its grasp. As Damian went to activate the wrist ray, a cloud of ink spurted right into his face, and he lost track of it.

Dammit! Damian let out some uncouth words under his breath, and banged his hand on the rock.

Hunting for food was difficult. Theoretically it should’ve been simple. Find something edible, kill it, bring it back, but everything Damian found was either too small to be worth the effort, or too big to risk his life. Multiple times Damian was forced to dive around corners or into claustrophobic cracks as ocean behemoths crossed his path. He couldn’t even find a patch of seaweed or algae this deep into the trench.

He was running out of options as the sun began to set above. Damian was starving himself, and it was getting frustrating. His body was not adapted to thrive in these waters, or maybe it was, and he just didn’t know how.

Either way, the exhaustion of the hunt began to take its toll on him. Far from providing for Phantom’s recovery, he had only wasted his own energy for nothing. Each failed kill, each accumulated bruise left him more and more anxious. That was why when he spotted a lone anglerfish creeping up from the depths, Damian decided to challenge it.

She, for male anglerfish were absolutely tiny satellites to the females, drifted into the twilight zone where Damian caught sight of her. She was almost half his size, and her teeth seemed as big as his fingers Her lure glowed brightly against the darkness of the deep ocean, as little fish wandered closer to the ‘sun’ and got chomped for their troubles. She was truly beautiful.

Hiding behind a small shelf, Damian aimed the wrist ray. The gills should allow him to subdue her quickly. Then securing the kill should be easy.

Damian waited. Just a little closer…

Then he fired.

The light of the shot was almost blinding. When the glare faded, Damian saw not a dead anglerfish, but a very much alive one dashing away. No! Damian sprung into a sprint after her. This may well be his last chance to get anything edible. He had to give chase.

Thankfully he’d gotten a lot of practice the last few others. As the anglerfish tried to round a corner, Damian grabbed its tailfin with his claws, digging in to try and slow it down.

Instead, the angler swerved to the side. Its powerful muscles slammed Damian against the rocky wall. Damian cried out in pain, and his grip loosened enough for the angler to get away.

Damian groaned. Not another one.

Damian lay there, dizzy from pain and exhaustion, watching morosely as the scraped scales healed themselves before his eyes, taking up valuable energy that he did not have to spare. Night fell. Without light, the next few quarries would be even more difficult, if not impossible. What he would do for Alfred’s cooking right about now. He would never make trouble at the dinner table again, if he ever got out of this alive.

His lateral line spiked up again, but Damian just felt tired. Sighing, he readied himself for another beating. How the might have fallen…

He noticed a beam of light shining from around a corner. Hushed voices followed. They were speaking Atlantean! Damian’s heart soared. He didn’t know they were this close to Aquaman’s territory! He knew there were a small number of settlements in the Pacific, but he never expected to stumble into one of them!

“Over here, I require assistance!” He called out.

The whispers rose into rushed conversation he couldn’t make out. Soon he found a light being shined on him, and two Atlantean soldiers, a man and a woman, pointing their spears at him. What?

“State your business here, siren.” The venom in the woman’s voice was palpable. Belatedly, Damian realised it was hasty of him to assume good relations between the two ocean peoples. However, this was his last shot.

“Please, my companion is injured and requires medical assistance. I swear on my name that we do not mean you harm.” Damian pleaded, with complete earnestness. He even added a whimper at the end to make himself look more vulnerable, more childlike and unthreatening, even if it was beneath him.

The man laughed. “Hah! I’ve heard that one before, punk. But if you think you’re gonna pull one over us easily, you’re shit outa luck. Your kind’s not welcome in these waters, now scram.”

Damian’s mouth gaped open. Did these people have not the slightest compassion? He often criticised his father’s habit of picking up strays, but deep down he knew that that trait was a quality of his character, and not a flaw. These Atlanteans could not even be bothered to spare him a glance outside of telling him to leave. Their eyes did not hold compassion, or sympathy, or even pity, only hardened wariness, and contempt.

“Please, I beg of you.”

The soldiers bared their spears at him. “I said scram, siren! Go back to your pod and stay there.”

Damian gave them his best glare as he turned tail and swam.

Only, he stopped once he turned a corner, but was still in earshot.

“Damn sirens, sinking to new lows. What next, a baby?” The male soldier muttered, his voice trailing off as the two returned to their patrol.

Patrolling soldiers meant an outpost, maybe even a settlement. And that meant food, medical supplies, and weapons. Damian knew a golden opportunity when he saw one. If these miscreants would not grant him the aid requested, then who was Damian to decide he didn’t need permission?

And so Damian stalked them closely. He trailed behind the duo of soldiers a dozen or so metres away, using his lateral line and nose to keep close track of their movements. A sense of calm quelled the ever present instinctual fear of being out in the open, as the familiarity of stalking targets washed over him. He almost didn’t have to try, with how terrible their situational awareness. If he were in king of the ocean’s shoes, he’d be very disappointed with his underlings’ performance.

Perhaps he’d have to snitch on them to Aquaman once this was all over. That would be suitable revenge.

The soldiers unwittingly guided him through the ravine, finally ascending. Above the cliff shelf, about two hundred metres away, stood an Atlantean settlement. Looks like he managed to catch them at the end of their route. Excellent.

Damian estimated the town’s circumference to be around ten kilometres, judging by parallax. He could just spot scores of Atlanteans going about their day, kicking their legs about to swim in a way that seemed so clumsy after seeing Phantom zip through the waves. The buildings stretched out from the flat sandy planes to jutting out from the sides of cliffs.

What was more important was the fields. Huge fields full of leafy plants he had never seen before. Along the cliff face, vines weaved between stone supports bearing strange fruits.

Damian grinned.

Now, all he needed to do was infiltrate.
