A Tail of Temptation [Merman to Mermaid Threesome TG]

Commissioned by Cooolooo

It’s against the law for mermaids to go to talk to humans, but when Mako and Finn spot a beautiful sunbather, they can’t resist approaching her. Only for the beautiful woman to turn out to be a long-haired man! Now Finn and Mako’s natural metamorphic genes are kicking in, and they are both transforming into mermaids, ready to be ravaged by this handsome human.

This story takes place in the same universe as Charlie's Sirens, Marina's Sirens, The Original Siren and The New Sirens, but is otherwise standalone.

Finn’s tail caught the light as he darted through a school of sardines, sending them scattering in a shimmering spiral. He laughed, glanced back over his shoulder and flicked his shimmering red tail teasingly.

“Come on, Mako! You swim like a barnacle with stage fright!”

Behind him, Mako rolled his eyes, though the corners of his mouth twitched. His dark green tail moved with calm precision as he followed, slower but deliberate. 

“You know, speed doesn’t make you smarter,” he called back. “Or less likely to get caught.”

“Oh, don’t be a sponge,” Finn shot back. 

He flipped backward mid-swim, letting the current carry him upside down for a moment. His golden hair floated wildly around his head, glinting in the filtered sunlight. 

“You’re just scared someone up there might actually see you.”

Mako snorted. 

“Yeah, well, someone down here might report us. There are still rules.”

“There are always rules. And they’re always boring. That's why we’re breaking them, remember? Besides, the last outpost is miles away, nobody is going to catch us here unless we’re real stupid.” 

Finn kept his tone light, but deep down, even he was starting to feel a little nervous. This was more than sneaking off campus; this was breaking the law. Mermaids and humans had lived separate lives for their entire existence, more or less. As human technology got better, Atlantis had made it law to stay hidden, at least until a few years ago when their scientists announced it was time for a change. If they didn't do something soon, Atlantis wouldn't stay undiscovered for long, so they decided to reach out to humans on their own terms using their new transformation technology. 

Merfolk were already gender fluid by nature, with three females to every male. Whenever that balance was disturbed, merfolk would simply change. Males becoming females or vice versa, based on what was needed. It was biological, and there was nothing that could be done to stop it. Thanks to that metamorphic gene though, scientists had even found a way to give a mermaid legs, if only for a little while. It had certainly helped relations improve, things were still rocky.

Nobody except the designated ambassadors was supposed to go this close to the surface or humans. If anybody knew two college-dropout males were floating around this close to the coastline, they’d be in serious trouble, and yet, the two of them hadn't been able to resist the thrill. Finn righted himself and stopped, hovering just under the surface. The shadow of the coast loomed above. 

“Coming close to the coast is one thing but going above is another.” mako pointed out, “We could be spotted.”

Finn sighed wistfully, watching the light dance only an arms reach away. 

“But look at it. Don’t you want to know what it’s really like? What they are like?”

Mako drifted up beside him, arms crossed. He was a head taller than Finn, with cropped dark hair and eyes the colour of stormy water—always watching, always calculating. He sighed. 

“Fine. Five seconds above the water. Then we turn back.”

He had that serious look on his face, but Finn knew better; he could see the excitement in his friend's eyes. Mako put on a big show of being serious, but he had been just as keen as Finn to come up here. He just needed the excuse; maybe that was why they were friends. Mako just wanted somebody else to take the initiative so he could follow. 

“Deal.”

They rose in tandem, their slick bodies slicing through the surface in silence. Salty air rushed around them. The world above was brighter and sharper. There was no water between them and the sky, no muffled sound, just heat, light, and birds in the distance.

“Whoa,” Finn whispered. “This is so weird…I can move so fast without the water in the way.”

He flung his hand back and forth so quickly it blurred. 

“The air feels weird on my gills.” Mako shivered before his eyes widened. “Wow, look at that.”

They both scanned the coastline, taking in the trees and the glittering skyscrapers of the city a few miles down the coast. It was so different to Atlantis, with its coral and stone. Neither of them had ever seen so much metal. Finn floated closer, eyes wide as dinner plates. 

“Imagine how it looks up close…”

Mako smacked him across the back of his head.

“Ow!”

“We can't go into a city!”

“I wasn't saying we would! I was just wondering is all…I want to see a human.”

“Me too, but we can't go swimming into a city bay and…”

Mako trailed off, and Finn followed his eyeline. There, tucked between high cliffs, was a small, hidden beach—untouched and quiet. A blonde woman lay on her stomach in the sand, sunbathing alone, her skin golden and smooth, hair like strands of sunlight spread over a white towel.

Neither of them spoke.

Finn’s grin faded, replaced by something softer. Mako blinked, unsure if he should duck back underwater or keep staring. Then Finn leaned toward him and whispered,

“Your turn to go closer.”

“What? We can’t, what if she sees us?”

“It’s just one human, and look, no bikini strap, she’s topless!”

Mako rolled his eyes.

“Seriously? You want to break the law just so you can see some tits?”

“...In my defence, it’s been a while. I keep striking out, no idea why.”

The figure on the towel shifted slightly, and Finn felt Mako’s tail shiver in the water next to him. 

“See? I know you wanna go get a closer look too.”

“Okay, just a little closer, we’re just looking, though, we can't talk or anything.”

“I know!” Finn hissed, already swimming closer.

He kept himself mostly submerged with just his eyes above the water line. This was the closest he’d ever been to a human before, it was making him tingle all over. 

“Actually, I’ll go.” Mako interrupted, swishing past. “I’m sneakier than you.”

“You were quick to change your mind, you didn't even want to be here.”

“So? We can't get caught, I’ll tell you what I see.”

“You’re going to talk to her, aren't you?”

“No!”

“Yes, you are! That’s not fair, I want to approach her, do you have any idea how sexy it’ll be to be the first merman she’s ever laid eyes on?”

“Yes! That’s why I want to do it!”

“Aha! I knew it!”

Their whispered argument was making the water choppy as the two pushed and pulled at one another. Suddenly, a shiver ran down Finn’s spine and he stopped. His scales seemed to stand on end, which was…strange. Sure, he was excited, but this felt like more than that; it was like his whole body had an electric current running through it. His fingers had pins and needles, and he felt his bones click slightly, almost like they were changing shape. Mako’s hands appeared over his shoulders, gripping them tightly as he whispered.

“Hey…Finn? Do you feel weird?

“Kinda…”

The tide moved beneath them, sending the two moving toward the shoreline. The subtle shift in water wouldn’t mean much to a human, but as merfolk, the two of them instantly knew they'd made a mistake. 

“The tide is going out.”

“Shit!”

The waves began to slowly push them closer to the shoreline where the beautiful woman lay, still somehow oblivious to the two of them. Finn felt his tail scrape against the sand, and he shuddered; it had never been that sensitive before. Suddenly, the figure moved, pushing herself up on her elbows and turning slightly. 

Finn ducked, pulling Mako into the shallow water with him. They were so close to the shoreline that there was barely enough water to cover them both. They pressed into the wet sand, and Finn had to hold back a laugh as Mako flailed, somehow struggling to press his chest into the ground. The panic must really have been getting to him. 

Finn shivered as he felt his butt breach the cool air of the surface again and thrust his hips down. Only for the water to lap at his hips again; why was this so tricky all of a sudden. It didn't help that his golden hair was in his eyes; god, it would take forever to get the sand out of it later. 

“Do you think she’s gone? I can't swim backwards in this little water.” Mako whispered. 

“Only one way to find out.”

Finn stuck his head above the waterline and dragged his hair from his eyes. The figure was still lying on her towel, but now she’d turned around and was looking at them quizzically. Only, it wasn’t a she at all. 

The human was a broad-shouldered, long-haired male with a square jaw and grey eyes that twinkled with curiosity at the two figures splashing in the shallows. 

“Uh, hi?” 

His voice sent a strange shiver down Finn’s spine, and he pushed himself up above the water, straightening his back. This was his first time meeting a human, and likely this human’s first time meeting a merman: he had to make a good impression! Which is why it was so unfortunate that he immediately fell face-first into the water. 

“What the hell, why is my chest so heavy?” He groaned, pushing himself up and feeling extra weight pulling him down. 

“Oh my Gods…”

Finn turned to Mako to ask what he was talking about, but the words got stuck in his throat. Mako looked wrong, or rather, she looked wrong. A heavy pair of breasts rested against her chest, big enough that they were partially submerged in the water even as she sat up straight. All mermaids were naturally big breasted, it was just their way. Still, it was shocking to see them on Mako, who’d always been male. Finn was about to start teasing her for changing, but then he realised Mako was staring down. He followed his friend's gaze to a second pair of breasts…on his own chest. 

“Huh?”
They had both become female, without even noticing! Finn’s mouth opened and closed in shock. All his life, he’d dreamed of meeting a human, and now this happens! 

“Are you two…okay?”

The human man stepped closer, his feet sinking into the soft, wet sand as they awkwardly dragged themselves up. 

“We’re fine! This… wasn't how I expected things to go.” Mako blushed. 

“Wow, you two really are mermaids though, I’ve seen the news but I never thought I’d actually see one, let alone two! You’re both…beautiful.”

Finn’s heart fluttered. She wasn’t accustomed to human interaction, let alone a human as striking as this one. She also wasn’t used to being a ‘she’. Now that she was aware of them, her breasts felt warm as a blush spread across her full body. The curious look in this human’s eyes was doing something to her insides, making them all hot and horny. She glanced at Mako, who was red in the face as well, his now long dark hair half covering his face; his eyes narrowed.

“If you think we’re beautiful, why aren’t you looking at us?” She asked. 

Finn realised she was right, the human man was staring at the sand, biting his lip.

“Well, because…Do you want me to get you both a towel to cover up?” 

Finn was aware of her own nudity, her breasts exposed and larger than most human women’s, but she felt no shame. It wasn’t like this was her idea and there was something in the way this human was trying not to look at her that made Finn feel special. 

“Why should we cover up?” Finn asked innocently.

“It’s just…your breasts are right there.” The man blushed, “You don't care if I stare?”

“Well, we’re not used to having them.” Mako said mysteriously, “We don't mind being exposed, do we, Finn?”

“Not at all.”

The man grinned, and his eyes flicked up and down both their bodies. Finn felt another bolt of arousal at his gaze; nobody had ever looked at her life that way before. So hungry. 

“If I am going to enjoy the view, I should probably introduce myself.” He chuckled. “Name’s Kai. And you two are…?”

“I’m Finn,” she said, gesturing to her friend. “This is Mako.”

Mako’s eyes locked onto Kai’s, and Finn noticed a spark of interest flicker between them. Mako’s scales glimmered in the sunlight, and her breasts, just as ample as Finn’s, rose and fell with her breathing. Kai’s gaze lingered on their bodies, his admiration obvious. 

“I’ve heard stories about mermaids, they don't do you lovely ladies justice.”

Kai sat himself comfortably on the sand between them and leaned back on his hands, showing off his broad chest. His cocky smile made Finn’s stomach and heart flutter. She’d secretly hoped this encounter would be an amorous one, but this wasn't what she’d pictured in her head at all. 

Still, she felt a warmth spread through her, a mix of embarrassment and excitement. She wasn’t used to being the object of such open desire, but there was something intoxicating about it. Mako leaned closer to Kai, her lips curling into a playful smile.

“Stories?” she teased. “What kind of stories?”

Kai chuckled, his eyes flicking between the two mermaids. 

“The kind that says you’re enchanting, dangerous, and irresistible. Seems like they got that part right.”

Finn couldn’t help but giggle, though she wasn’t sure if it was from the compliment or the way Kai’s gaze made her skin tingle. She glanced at Mako, who was clearly enjoying the attention. Mako’s hand reached out, her fingers brushing against Kai’s arm. His skin was warm, and Finn could see the muscles flex beneath his tanned exterior.

“Dangerous, huh?” Mako murmured, her voice low and husky. “What makes you think we’re dangerous?”

Kai’s grin widened. 

“Because I can’t stop looking at you both, and that’s got to be some kind of spell. You were where those stories of sirens came from after all.”

Finn laughed, a light, musical sound that seemed to surprise even her. She’d never considered that changing sex would change even the small things. She leaned closer to Kai, her curiosity getting the better of her. The air around them all was so charged, she couldn’t help but lean into it. 

“What do humans do when they meet mermaids?” She asked gently, batting her eyelashes at the human. 

Kai’s eyes darkened, his gaze intense. 

“I’ve never met a mermaid before, so I’m not sure. But I’m willing to find out.”

Mako’s hand slid down Kai’s chest, her touch deliberate and bold. Finn watched, her heart pounding, as Mako’s fingers traced the contours of his body. Kai’s breath hitched, and he leaned into her touch, his eyes closing briefly as if savouring the sensation.

Mako’s eyes met Finn's, and Finn nodded; this was so taboo. They weren't even supposed to be talking to a human, let alone lying with one. Maybe it was the hormones flooding their systems from the change, or perhaps it was the taboo and risk itself that was turning them on. Either way, the result was the same. 

“Maybe,” Finn said, her voice barely above a whisper, “we should show you.”

Kai opened his eyes, his gaze locking onto Finn’s. 

“I’d like that.”

Finn didn’t need to be asked twice. She shifted closer to Kai, her body brushing against his. His skin was warm, his scent a mix of salt and sun that made her head spin. Mako moved to his other side, her hand sliding around his waist, pulling him closer.

Kai’s hands found their way to Finn’s waist, his touch firm but gentle. She leaned into him, her breasts pressing against his chest, and felt his heartbeat quicken. Her hips were wider now, and Kai’s fingers traced along the line where her skin became scales. The touch was electric and her fins shivered in anticipation as they shuffled up onto the drier sand. Mako’s lips brushed against Kai’s neck, her kisses soft and teasing while Finn’s hands roamed over his shoulders, her fingers tangling in his hair as she pulled him down for a kiss.

Their lips met in a rush of heat and desire. Kai’s kiss was hungry, his tongue sliding against hers in a rhythm that left her breathless. Mako’s hands moved lower, her touch bold as she explored his body. Finn moaned into the kiss, her senses overwhelmed by the taste of him, the feel of his skin, the sound of his ragged breathing. She’d mated as a man before, but she felt like a virgin again. The scales that covered her front started to retract, revealing her brand new pussy, pink surrounded by the red of her scales. 

The sand beneath them was warm, the ocean’s roar a distant backdrop. Mako’s lips left Kai’s neck, trailing down his chest, her tongue tracing the contours of his muscles. Finn’s hands moved lower, her fingers brushing against the waistband of his speedo. She hesitated for a moment, her heart racing, before slipping her hand inside. She’d never been with another male before, but she had been one, and that meant she knew exactly how to touch him. 

“Oh damn.” Kai gasped, his body tensing as her fingers wrapped around him. 

He was hard, his skin hot beneath her touch. Mako looked up, her eyes sparkling with mischief, as she shuffled Finn aside and took the length herself. She gave Finn a wink, then slid down to take Kai in her mouth. Finn watched, mesmerized, as Mako’s lips moved up and down, her tongue swirling in a way that made Kai groan with pleasure.

“Fuck,” he muttered, his hands gripping Mako’s hair. “You’re both going to kill me.”

Finn couldn't help but giggle; for all her big talk of being cautious, Mako was being even bolder than her. It was always the quiet ones who were repressed and crazy. 

She snuggled up to Kai’s side as Mako’s head continued to bob in his lap. She leaned in, her lips brushing against his ear. 

“We’re just getting started.”

Mako sat up, her breasts heaving as she smiled at Finn. Without a word, they switched places, Finn taking Kai’s length into her mouth, her lips closing around him with a slow, deliberate motion. He tasted heady, there was a distinct lack of salt tang on his skin that all merfolk had. It made him all the more unique. 

Kai’s head fell back, his hands gripping the sand as he fought for control. Finn’s tongue swirled around him, her mouth warm and wet, her technique instinctual despite her lack of experience. Mako’s hands roamed over his body, her touch teasing and playful, her lips brushing against his chest as she watched Finn work. She licked at his shaft, then moved down to tease his balls, burying her nose in his manly scent. 

A glance upwards showed Mako rubbing the man's shoulders as she allowed him to lie back against her breasts. She gave Finn a wicked grin; this was the wildest, most insane thing theyd ever done! Her lips trailing kisses up Kai’s chest as she leaned in for another kiss. Kai’s hands found their way to her breasts, his touch reverent as he cupped them, his thumbs brushing against her nipples.

Instantly, she felt herself getting wetter. Her breasts were so sensitive she mewled at the touch, pressing them closer so his thumb crushed against the nipples.

“Don’t forget about me.” Mako begged, “That looks lovely.”

Finn groaned with jealousy as one of Kai’s hands left her to feel up Mako. Now they were both his playthings but one hand just wasn’t enough. 

“Maybe you two could play with each other a little,” Kai said roughly, “I want to see how you work.”

Finn whimpered as Mako’s fingers slid along her tail, right to that sensitive bunch of scales that had pulled back to reveal her sex. Her touch was light but insistent. Finn gasped, her body arching into the touch, her senses overwhelmed. She had never felt anything like this, the pleasure building in her core, the heat spreading through her veins.

Kai’s lips moved to her neck, his kisses hot and hungry. Mako’s fingers trailed inside and began to thrust in and out of the mermaid’s new pussy. They moved faster, her touch firm as she teased and pleasured Finn. The mermaid’s moans filled the air, her body trembling on the edge of release.

“Kai, Mako,” she whispered, her voice desperate. “I—”

A wave of pleasure cut off her words, her body convulsing as she came, her cries echoing across the beach. Mako’s touch didn’t stop, her fingers continuing their rhythm as Finn rode out her orgasm. When she finally came down, breathless and trembling, Kai was looking at her with a mixture of desire and smug satisfaction.

“You bitch,” Finn pouted playfully, “I wanted my first orgasm to be from him.”

“There now, no need to fight, there is enough of me to go around,” Kai replied. 

He shifted, his body moving with purpose as he positioned himself between them. Mako’s hands roamed over his chest, her lips meeting Finn’s in a deep, passionate kiss. Kai’s hands gripped Finn’s hips, his touch firm as he guided her onto him. It was slightly awkward with the tail but somehow, they made it work. 

She gasped as he entered her, his thickness filling her completely. Mako’s hands moved to Finn’s breasts, her touch gentle as she teased and pleasured her. Kai began to move, his thrusts slow and deliberate, his eyes locked onto Finn’s as she undulated her tail.

The sensation was overwhelming, pleasure building with every movement. Mako’s lips trailed down Finn’s neck, her kisses soft and teasing, her hands roaming over her body. Finn’s head fell back, her moans filling the air as Kai’s pace quickened. Mako’s body pressed against Finn’s back, her breasts brushing against her skin, her hands moving lower to grip the other mermaid's tail. Finn could feel her open pussy pressing against the sensitive scales at the back of her tail. Mako was fucking herself against them. Kai’s thrusts became frantic, his breath coming in ragged gasps. 

“I’m close,” he muttered, his voice hoarse.

“Leave some for me, big fella,” Mako whispered. 

Kai’s body tensed, his movements becoming urgent as he surrendered to the pleasure. His cry echoed across the beach, his release hot and intense. Finn followed soon after, her body convulsing as she came, her cries mingling with Mako’s as they found their release together.

They collapsed onto the sand, breathless and sated, their bodies tangled together. The sun dipped below the horizon, casting the beach in a soft, orange glow. Finn’s heart was still racing, her body buzzing with the aftermath of pleasure. 

“This is the best day.” Kai sighed happily. “When I found out mermaids were real I almost didn't believe it.”

“Are we really so fantastical?” Mako asked, trailing circles across Kai’s chest with a delicate finger. 

“Honey, fantastic doesn’t begin to cover it.” 

Kai stretched out his arms, and Finn and Mako each snuggled into his sides. Finn sighed happily; if it weren't for the sun slowly drying out her scales, she’d happily stay here for hours. 

“We should probably get back.” Mako sighed sadly, “We’re not exactly supposed to be here.”

Kai sat up slowly.

“Oh?”

“Only ambassadors are supposed to be meeting with humans at the moment,” Finn admitted, “Us regular folk are supposed to stay in Atlantis, we’re not even supposed to come near the coast, let alone…meet humans.”

“We did a lot more than just meet.” He snickered, and Mako snorted with laughter. 

“That’s an understatement.” 

“Is it true you can get legs if you want?”

The mermaids shook their heads.

“The ambassadors are working on these nanites that can change our tails into legs, but they’re just for ambassadors.” 

“Well then, I guess the way forward is clear,” Kai said confidently and the two mermaids shared a look of confusion. 

“What do you mean?”

“You two have to become ambassadors so that we can do this again!” Kai laughed, “You think I can go back to sex with regular old human women now that I’ve tasted what a threesome with two mermaids is like?”

Finn giggled in delight; this guy had confidence to spare, that was for sure. He had a point, though; that was the most erotic thing Finn had ever been a part of. She was certainly in no hurry to be male again or sleep with another mermaid. 

“Maybe we can sneak back here, the two of us.” Mako winked, “Do you come here often?”

Babe, I’ll come here every day if it means meeting you both,” Kai grinned, giving them both a kiss before assisting them to the water. 

“No promises, but we’ll try,” Finn whispered, letting her hands linger on his arm a second longer than necessary before slipping back into the ocean.

Kai waved to them from the shore and watched them go, Finn’s heart felt surprisingly heavy as they slipped back below the waves. As soon as they were deep enough she let out an excited shriek.

“I can't believe we did that!”

“I know!” Mako gasped, “Oh my God, and he was so…alpha male. It was incredible, I mean, he had enough masculine energy to turn us both female, I just…”

She swooned dramatically.

“We have to come back.”

Finn twirled through the water, enjoying how light and buoyant it made her new breasts feel. 

“Absolutely! We already know the way up here, nobody caught us, I bet we can do it again!”

Mako looked like she was about to reply when her smile fell, and her eyes fell on something over Finn’s shoulder. Finn was about to ask what it was when she felt her back hit something warm. She turned and saw a stern-looking, wide-chested mermaid wearing a security badge around her neck. 

“Uh oh.”

The mermaid raised an eyebrow and glowered down at the terrified mermaids. 

“What was that about sneaking out again?”

~

Kai sat alone on the sun-warmed sand, his broad shoulders hunched slightly as he stared out at the rolling tide. The late afternoon sky burned gold above him, casting long shadows behind the dunes. His long blonde hair, damp from an earlier swim, clung to the sides of his face in lazy curls. His hands were clasped loosely between his knees, idle fingers digging little grooves in the sand.

He was waiting. Again.

It had been three weeks since he'd met them—Mako and Finn. Two mermaids, their voices as clear and soft as wind chimes, with bodies made for sin. His jaw had dropped when he first saw them frolicking in the shallows, arguing about something which turned out to be him. Then, when they had returned his flirtations, his heart had damn near stopped.

The meeting had been brief, like a dream slipping away as soon as it was grasped. But it had happened. Kai could still feel the salt-sweet breeze on his face as they spoke to him, their laughter ringing in his ears, their soft scales under his fingertips. The sound of Finn’s moans as she came around him echoed through his mind at night, and the feeling of Mako’s fingers tracing circles on his chest haunted him. 

He’d been half joking when he said it but it turned out to be true: he couldn’t go back to human women, not after tasting them. They’d promised they’d come back. And yet… they hadn’t. He'd returned to the beach every day since. At first with excitement, then later, with quiet hope. And now, with something heavier. A kind of sorrow that tightened in his chest every time the tide rolled in and left only foam behind. He knew they probably wouldn;t be back straight away, it was against the rules after all but he had thought they would have appeared at least once by now. 

“Maybe they got caught,” he told himself, “Maybe they are in mermaid jail or something.”

His friends had laughed when he told them.

"Mermaids? Seriously, Kai?"

"Sure, bro, and I suppose they gave you their underwater phone number?"

“I think it's all conspiracy, those mermaids on the TV are totally fake.”

He'd tried to get them to see. Even invited them here, hoping that maybe, just maybe, Mako and Finn would return when he wasn’t alone. But every time they came, the sea stayed silent. Just waves and gulls and the wind. Eventually, his friends stopped coming too, shaking their heads and muttering about saltwater getting to his brain. Well, that and him just being horny and wanting to one up Chris’ story of meeting a hot lady of the night while off the clock. 

Now he sat alone, the cold edge of doubt creeping into him. Maybe they were never coming back. Maybe they’d been caught, or punished or worse, what if they plain forgot about him? They were mermaids; gorgeous ones at that, those two could have any man they wanted. Human or merfolk. Maybe he was just an exciting thrill to them, easily forgotten. 

Kai looked down at the sand beneath his feet, then out again to the horizon. The sun was beginning to dip, its light catching the tops of the waves and painting them in fire. He let out a long, slow breath.

"I guess you’re not coming," he murmured.

And then, just barely, a sound. Like a splash. Not far out.

He froze. The sea stilled for a heartbeat. The wind even stilled; like it was holding its breath just like him. And then something moved beneath the surface. Something graceful. Two shapes, gliding side by side, just below the waves. Kai’s heart surged and he jumped to his feet just as two beautiful, familiar faces appeared above the waves. Kai was running down waist deep in the water before they could drag themselves up on shore.

“You’re back! I thought you’d forgotten about me!”

“Forget you?” Finn giggled as he raised her into his arms. “Never!”

“Help us onto shore, we’ve got a surprise for you!” Mako laughed as the three of them dragged themselves out of the waves. 

“When the authorities found out what we did, we were in big trouble.” Finn explained as he placed her down on the sand. “Real big trouble.”

“Like, holy shit I thought we were done for!” Mako laughed, “But then, the observation station saw you here everyday waiting for us.”

Kai’s cheeks went pink; he hadn;t realised he’d been watched. 

“They decided that in the interest of human-merfolk relations, more ‘normal’ merfolk should be allowed to meet more 'normal humans’ and the like,” Mako grinned, “To make things feel more natural.”

“So you got permission to come visit?” 

“More than that.” 

As she spoke those words, Kai’s eyes were drawn down to Finn’s beautiful red tail. The scales seemed smoother today. He watched in amazement as the scales got so smooth they started to melt into the skin itself and grow pale, turning the same creamy colour as Finn’s skin. Mako was starting to change now two, their beautiful mermaid tails transforming into legs before his very eyes. 

“We have these nanites; they are still experimental, but they can change a mermaid into a human and vice versa, at least temporarily.”

“So if you get us both some pants, we can come spend some time with you…maybe some friends if you have them?”

Mako batted her thick eyelashes as she said that last part, and Kai felt his heart begin to race. He was torn between jealousy and the overwhelming need to show and share his two bathing beauties. Nobody would care about Chris’ stories again once he brought two mermaids to campus. When the change was done Kai offered his hand to Finn who wobbled to her feet like a newborn deer, giggling and clinging to him as he gave her a lesson in walking. 

“This feels so strange, and it's so weird to be so…exposed.”

Where once had been scales was now a neat mound of hair between her legs and Kai grinned.

“Well once you’ve both got the hang of these things, why don’t I teach you some fun new positions they open up.”

Finn gripped his arm and stumbled, sending them tumbling to the sand where she landed on his lap, knees either side of his hips. Kai’s cock twitched in his speedo and he wiggled his eyebrows.

“Just like this.” 

“I think I am seeing the appeal.” She giggled.

“Save some for me!” Mako pouted and the three of them all laughed. 

Kai ran his fingers through Finn’s hair and pulled her close.

“Maybe the pants can wait.”
