Chapter 3
The more things change, the more they stay the same. That’s all Max could think as he stared at the odd waterproof book. He had hoped textbooks were only a surface thing, but Atlantis University was still a university, and Merfolk had to study just as much as humans did. He stared at the page of the book; it was some merfolk classic apparently, but Max could barely keep his eyes open to read it.
His eyes slid over to the couch. Charlie was reclined, Jamie curled up on one shoulder, one arm around Harriet’s waist, and the other holding his own textbook. He was almost at the end.
“I can’t stand this.” Max sighed. “Charlie, you can write the report, right? I’ll just reword it.”
“You really need to start doing your own work, Max.” Charlie chided.
“How am I supposed to read a whole novel and write an essay on it in a week?”
“Well, if you had come to class, you’d have the analysis notes, and you would have started a week ago, like I did.”
Max grit his teeth; he wasn’t a huge fan of Charlie’s new attitude. It had only been one afternoon, and already he was acting like hot shit because he was the only one who was still male. It made Max second guess going to that party. He knew who he was at parties, he was the king, the big drinker, the flirt, the one who ended up getting a blow job from one woman and falling into bed with another by the end of the night. Now though? He had no idea. Charlie normally hung out on the sidelines; Max did his best to chuck him a girl now and then but he never had the charisma to actually keep them or score. Now, though, would their positions be reversed? The idea made him shudder.
“Come on, you never cared if I copied your stuff before. We both know I’m not going to need essay skills or whatever once college is over.”
“You can't be sure…”
“Oh, I can be. You saw the scouts last year, they had me on the shortlist. Next year, I’ll be picked up for the big leagues, and then kids will have my face on cards…”
“Never hurts to have a backup.” Charlie pointed out.
“He’s right.” Jamie nodded. “Charlie is the smartest of us, you should listen to him more.”
“Oh, like you’re not copying off him like always as well.”
“Actually,” Harriet blushed. “We’re not, Charlie convinced us to give it a go. It’s hard, but he’s right, we have to learn to stand on our own two feet, or uh, fins.”
The two mermaids giggled, and Max felt bile rise from the back of his throat. Those two giggly girls were his baseball teammates; he hardly recognised them! They were acting all soft and submissive! It was weird!
“The party is soon, we should get ready!” Harriet said after a moment, and Max checked the clock.
“You’ve got an hour.”
“I know, but it turns out the girls weren't making us wait around as a tactic; it actually does take longer to get ready!” Harriet replied. We stopped by a few shops on the way back here, and I got some makeup to try.
“Makeup, dude, listen to yourself.”
Harriet just shrugged.
“Exchanges are all about experiencing different cultures, right? Embracing being a mermaid is just part of that, right? Besides…haven’t you ever secretly been curious about what it was like to be a girl?”
“Not to the point that I wanted tits out to here!” Max snapped, poking a finger into the supple flesh and flinching slightly; he still wasn’t used to them being there.
“It’s going to be a long semester if you spend it hating every second,” Jamie said quietly. “Come on, Harriet.”
They swam off to Harriet’s alcove, and Max could hear them opening tubes and pouches with gasps of delight. It was just him and Charlie, the latter of which finished his book and put it down. Max refused to look up even though he could feel the merman’s eyes boring into him.
“They are enjoying themselves a lot more now,” he said quietly. “I don’t want you to be miserable this whole trip…”
Max shifted uncomfortably.
“I know, I just…” he hated how wispy and submissive his voice sounded and cleared his throat. “Look, just because we are in Atlantis doesn’t mean we have to actually act like real merfolk. I’m not about to turn into some submissive harem member just because I have a tail now.”
He jutted out his chin in defiance but almost instantly deflated as Charlie swam over and placed a gentle hand on his shoulder.
“I’m not asking you to change that much, just to try embracing something new. The others are still them, they’re just…embracing a different side of themselves. Doesn’t that sound better than pouting for a whole semester?”
A gentle sort of authority washed over him, and Max felt conflicted. Charlie’s kindness felt so nice, he knew it was genuine too. It wasn't like he was trying to manipulate him. But at the same time, Max had never once been submissive in his life! He didn’t want it to feel so…good. Never in a million years would he have suspected he’d be tempted to melt into another man’s arms. Charlie’s hand was so warm on his shoulder, the grip gentle but firm. He wanted to feel those fingers threading through his long, red hair…and to his utter humiliation, he wanted to feel those fingers in other places, too. He was so shocked by the feelings welling up inside him and inside his new, hidden away pussy, that he shot backwards. His hair fanned around his fan, and Max found himself spluttering, desperately pulling random strands out of his face and blushing profusely.
“Maybe you should pin that back,” Charlie suggested, swimming over to Harriet’s little alcove and returning with two hair clips decorated with pearls a moment later. Max felt his whole body freeze, and fight or flight instincts paralysed him in between. Charlie’s hands gently pulled the hair back from his face and pinned it with the clips before pulling away.
“There! You look lovely.”
Max could feel his cheeks turning the same colour as his hair. Oh God, what was wrong with him? Why was his heart beating so fast in his chest? Why couldn’t he stop staring at Charlie’s kind eyes and wanting to be closer? You could cut the tension in the room with a knife until suddenly, Jamie appeared.
“What do you think?” She gripped, twirling to show off the impressive braid Harriet had done for her.
“You look great! It’s good to see you smiling.” Charlie said and Jamie beamed.
Max felt that bitter taste appear on the back of his tongue again, but this time, he realised what it was: jealousy. He buried the feelings, denying them as much as possible as he swam for the door.
“Let’s just go to the party…”
~
Max had hoped that he would feel like himself again when they arrived. This party was basically the same as any college get-together, except…underwater. The only big difference was that the drinks were served in enclosed little containers made of porcelain or something. Max pressed his back against the wall, trying to melt into the shadows. Is this how Charlie used to feel back home? For the first time, he felt a twinge of guilt; he’d thought throwing a girl his way once in a while was enough but maybe he should have invited him to play beer pong or something. It was lonely on the sidelines.
“Hey, are you new, I don't think I’ve seen you before?”
A blonde mermaid nudged against his shoulder playfully.
“Uh, sort of. I am here on exchange.”
“Oh! You’re one of the humans? How exciting!” The mermaid grinned. “I love your hair! How do you handle having so much hair up on the surface? Wouldn't it weigh a lot without the water to help?”
Max bit his lip.
“Um, actually, on the surface, I’m…a man.” He whispered the last two words shamefully but was met with a warm smile.
“Oh, that's exciting! It must be fun to be a woman for a bit! I enjoyed being a man well enough, but I much prefer this.”
The fact that she not only readily accepted him but also admitted to being a guy herself was…shocking, to say the least. The shock must have shown on his face because the woman’s brow furrowed.
“What’s wrong? Don't you like your body?”
“Of course not!” he responded, “it’s…well, I have I have boobs!”
“...So? They’re fun, right?” She shimmied her chest a little, and Max almost choked on his drink. Normally, the sight of a pair of beautiful breasts jiggling in his face would have him hot and hard, but this time, there was only surprise, no arousal.
“I’m going to get another drink.” The mermaid smiled. “Try to enjoy yourself a little!”
Max pouted, he wished people would stop telling him that and just leave him to be miserable in peace. After a few minutes, though, he looked down at his chest, taking in the cleavage and giving them a little jiggle. The feeling was…different, but not bad.
“I guess these aren’t so bad…”
His biggest problem had been the humiliation of being transformed into a woman but…it was hard to feel ashamed or even care when nobody else seemed to. If anything, he was getting more smiles and compliments from strangers than he ever had. That felt nice if nothing else. Maybe...maybe being a mermaid temporarily could be fun. Max swam to the bathroom and looked at himself in the polished mirror. The red-haired beauty staring back at him was still a stranger but maybe she didn't have to be. His fingers brushed the mother-of-pearl clips in his hair and remembered Charlie’s fingers doing the same.
“Okay…let’s give it a try.” Max took a deep breath and forced himself to smile. “Hi I’m…I’m uh…Marina.”
The name felt much more natural on his tongue than Max's, especially with his slightly musical voice. Marina's smile became genuine and widened as she took in her new face, looking beautiful and happy for the first time.
“Welcome to the world, Marina.” She whispered to herself before floating back and examining her body properly for the first time.
It was surprisingly easy to think of herself as a she. Maybe it was the metamorphic gene or just part of being a mermaid; she couldn’t be sure. Didn't Charlie mention something about merfolk being generally more genderfluid by nature? Maybe. She should probably start listening to him more. Marina opened the door and went back out into the party. There were butterflies in her stomach; it was time to embrace the feminine side Harriet and Jamie had talked about. Her usual confidence was still shot, though and Marina found herself floating by the sidelines again, unsure how to start, at least until she heard a familiar voice.
“Max! There you are, I was worried you left.”
Her heart fluttered for a whole other reason.
“Charlie….you were looking for me?”
“Of course.” He said with a concerned expression. “I probably shouldn’t have left you alone, considering how you’ve been feeling about this whole mermaid thing.”
He was worried about her, which made Marina’s cheeks threaten to blush, but she held it back.
“I’m not some damsel in distress.” She said crossly, “And…I thought maybe I’d give this whole being female thing a go. Not because you told me to, though!”
“Hey! That’s great! Are you going to pick a new name?”
“...Marina.”
“It suits you.”
“O-Of course it does! I wouldn’t pick a name that didn't suit me, would I? What, do you think I’m an idiot?”
Marina crossed her arms beneath her chest and pouted. She felt irrationally annoyed by Charlie’s presence, but at the same time, she didn't want him to go. All of a sudden, the most embarrassing and horrifying realisation crashed over her like a wave. She had a crush. A crush…on Charlie! She’d been female for all of a week, and suddenly, she was catching feelings for him of all people? Marina wished a whirlpool would form and swallow her up.
“Well, did you want to come get another drink with Harriet and me? They have this great Atlantean alcohol-”
“I don’t need you to get me a drink. Or check on me. You may have some silly male instinct to protect me or whatever, but I don’t need it.”
Panic welled in Marina’s chest. Accepting herself as a woman was one thing, but to have a crush on a man? Especially Charlie? No, that had to be the hormones talking, and she refused to indulge them. These feelings would fade, she just had to ignore them until then.
“Okay, if you’re sure.”
“I am. I don’t need you looking after me. Nothing has changed! I am still in charge.”
Even as he said it, the words felt wrong. That natural submissiveness he’d been feeling was compelling him to back down, but he refused. Charlie gave him a little wave and swam off to join another group of mermaids gathered around a table drinking, and instantly, Marina felt lonely. She wanted his presence, even if it was irritating as hell.
“Get a grip on yourself…” She muttered.
What she needed was some strong alcohol and attention from somebody other than Charlie. Surely not all mermaids were straight, she would find herself a nice lesbian girl to make out with; at least then, she could feel a bit more in control. Deep down, she was still the same person she had been on the surface…just curvier. Marina set out to do what she did best at parties: flirt. But no matter how hard she tried, her heart just wasn’t in it. None of the beautiful, busty mermaids that had lured her here in the first place were attractive. At least she wasn't attracted to them anymore. For a second, Marina was worried this fucked up metamorphic gene had somehow stopped her being attracted to women, but the mermen didn't do anything for her either.
Except one.
No matter where she went, she could hear Charlie’s laughter clear as day through the party noise. It made her heart lift and squeeze painfully. It was as if her body had forgotten any other options existed; all it wanted was him. Unconsciously, Marina found herself drifting back toward him throughout the night, catching herself, then swimming to the other end of the house. She couldn’t enjoy the feeling of alcohol in her veins because the more she drank, the more her body yearned to be touched and she refused to let Charlie claim her.
Then, as she downed her third drink, or was it the fourth? She noticed something. Charlie had disappeared from the group he’d been drinking with. Her mouth went dry, something that shouldn't have been possible living underwater. Marina knew what it meant when people mysteriously disappeared at parties like this; was Charlie…hooking up with somebody? Jealousy surged through her, and pride be damned, she swam hurriedly through the house, trying to find him. She turned a corner and froze.
There was Charlie, pressing himself against the wall, both hands grasping Harriet’s chest. She was moaning as he tweaked her nipples and Marina felt her pussy quiver in response. Her jealousy turned from a flame to a raging inferno; she couldn’t take her eyes off Charlie’s hands as they pressed and played with Harriet. She was the only one with a chest bigger than Marina's, and Marina resented her for it for the first time. She’d spent the last few days wishing her tits would disappear, now she wished they were bigger.
Eventually, she tore herself away from the sight and forced herself to swim home.
“This is temporary.” She hissed, trying hard to convince herself. “Just ignore and in a few days, you’ll be able to laugh it off.”
~
That turned out to be wishful thinking, unfortunately. If anything, her crush on Charlie seemed to grow with each passing day. It stopped being a pure physical attraction and started morphing into more. The way he spoke so gently, yet with such authority, the way he made her want to submit to his every will without even trying, the way he smiled when she put a little extra effort into her appearance. It was all so hard to ignore. Marina was at war with herself, simultaneously craving his approval and attention and hating how much she enjoyed it. That was how she found herself organising his notes and books while he was gone without even realising until he swam back in the door and gave her a grateful smile.
“Hey, did you do this? Thanks, Marina.”
“I’m doing it for everybody.” She lied quickly. “This place is a sty. It’s not like I like you or anything, I’m not giving you special treatment!”
She quickly swam over to Harriet’s desk and began shoving papers about, making a show of organising her things as well, though there was no sense of quiet satisfaction she’d gotten from doing for Charlie.
“Marina, I think we should talk-”
“I think you should mind your own business.”
“I know you’re still mad at me for this whole mermaid thing-”
“No, I’m not!”
“Marina, for God's sake let me speak!” Charlie said, frustrated and adding an edge to his voice.
The sound made a shiver run down Marina’s spine all the way to the tip of her tail, and she couldn't help but comply. The urge to listen and submit to him was overwhelming and a massive turn-on.
“Marina, I have tried being patient,” Charlie said firmly. “But I think it’s time you get over yourself.”
“G-get over myself!?”
“It’s not my fault this happened to you. If you’d paid attention, you would have known there was a chance this could happen.”
“I know…” She sighed, squirming a little under his gaze. “But I swear, I’m not angry with you anymore.”
“Then why are you so pissed off all the time?” He cocked his head to the side in concern. “Is there something you’re not telling me? If I can help I will, you know that, right?”
Marina bit her lip; it was so tempting to tell him the truth. That her frustrations were born of desire. She could swim right into his arms and let Charlie take care of her, just like his new merman instincts told him to do. God, it would be wonderful. But she could never. She refused to give in.
“No, I am fine.” She said instead, “You’re imagining things. Now, if you’ll excuse me.”
She swam off to her alcove and dove right under the covers of her bed, face burning. She wasn't sure whether to be sad or glad when Charlie didn’t follow her. She busied herself with trying to read that stupid book for her essay. She wasn’t even halfway through and the assignment was due soon, but reading was torturous. But not as tortuous as the sounds that met her ears after a few hours of trying.
Pleasured gasps and breathy laughter made Marina’s cheeks burn and her pussy wet. She recognised those sounds, Charlie and Harriet were going at it again, just like at the party. She could hear Harriet’s soft moans as Charlie played with her tits and Marina felt her nipples stiffen in response. She wanted that and she hated herself for it. It was getting harder and harder to resist her own desires.
Marina forced her eyes closed, willing herself to fall asleep and block out the sounds. Time must have passed because when she blinked her eyes open all the main lights were out and the water around her was silent. She rolled, floating upwards slightly and felt a tug at her chest.
“Wh…what?? How have my breasts gotten bigger?”
They were at least E cups now, maybe even bigger. Her metamorphic gene must have activated again, making her grow thanks to her one sided rivalry with Harriet. God, how embarrassing.
Marina tossed and turned in her bed, her traitorous mind continued to conjure sinful images of her and Charlie together. She tried to convince herself that it was just a harmless crush. But deep down, Marina knew her desire ran much deeper. The tension between them was palpable whenever they were close, and she couldn't help but imagine what it would be like to surrender to his strong embrace.
She pictured his mesmerising eyes, the way they seemed to see right through her, and the playful smile that always made her heart skip a beat. Her tail flicked restlessly, betraying her growing restlessness. She knew she had to confront these feelings head-on, if she could just convince Charlie and herself that she wasn't going to submit to these feelings, maybe they would go away.
In a second she was up and swimming from her own alcove toward Charlie’s, heart hammering in her chest. Marina took a deep breath, her gills flaring as she tried to calm her nerves. There was a faint glow behind the seaweed curtain, Charlie was still awake. It almost felt like he was waiting for her and Marina hated how happy the thought made her. She took a moment to steel herself, then brushed the curtain aside and slipped inside.
Her gaze was immediately drawn to Charlie, lounging on a bed of soft coral, his powerful tail draped casually over the edge. His scales shimmered in the faint light, and his bare chest rose and fell with each deep breath.
"Marina," he rumbled, his voice deep and commanding. "It’s late, is everything okay?"
Marina's heart pounded so hard she was afraid he might hear it. She tried to maintain her usual feisty demeanour, but her voice trembled as she replied.
“Fine. Actually, no, I came here to tell you to remember your place.”
“My…place?” Charlie said with a cocky smile.
“Look at me!” Marina pointed to her chest. “I went up a cup size because you got handsy with Harriet! You have to stop.”
“That’s not my fault, I think that says more about you than me, Marina.”
Charlie pushed himself up, his tail rippling with a fluid strength that sent shivers down Marina's spine. He swam towards her with a purposeful stride, his eyes never leaving hers.
“I…you’ve gotten all high and mighty since we arrived. I…um, I wanted you to know that I won’t submit to you like the others.” The fire slowly died in her voice as he got closer. By the time she finished the sentence, her voice was little more than a sensual whisper.
Marina's cheeks flushed, and she knew her eyes must be giving away her true desires.
Charlie closed the distance between them, his presence overwhelming yet intoxicating. He reached out, gently cupping her cheek.
"Marina, I know it's hard, but I think we both know that you really want to give in to your new mermaid instincts, don’t you? There is no shame in it.”
Marina's breath caught in her throat as his thumb brushed against her lower lip, sending sparks of pleasure through her body. She couldn't deny the truth any longer. She wanted him, needed him, with an intensity that scared her.
"Please..." she whispered, her eyes pleading. "I want to, but..."
“Don’t let your masculine pride ruin what could be magical…” Charlie whispered huskily, and he wrapped his arms around her. “I'll take care of you."
Oh, how she wanted that. She wanted to be looked after for once and have somebody else take the lead. No more macho posturing, just gentle caresses. Marina relaxed into his embrace, her tail entwining with his as if they were meant to fit together perfectly. She could feel the hardness of his cock, hidden behind his scales, pressing against her soft belly. Her own pussy, hidden behind her tail scales, began to throb with anticipation.
Charlie nuzzled her neck, his hot breath sending shivers down her spine.
"Let me show you how good this can be," he murmured, his lips trailing kisses along her jawline.
Marina moaned softly as his hands roamed over her body, caressing her curves with a possessive touch. He gently guided her towards the bed of coral, his tail guiding her movements with subtle dominance. As they lay down, Marina's scales parted willingly, via some instinct she couldn’t quite control, revealing the entrance to her most intimate place. Charlie's eyes darkened with desire as he gazed upon her exposed pussy, glistening with arousal. She watched as Charlie’s own scales shifted, revealing a thick manhood that took her breath away.
“Were you always so big?” she whispered and Charlie nodded.
“I just didn’t have the confidence till we got here but now…I know how to use it.”
He positioned himself against her, and then, with one swift motion, he thrust forward, penetrating her in one smooth stroke. Marina gasped, her body trembling as she felt the full length of him filling her. Charlie's cock was thick and warm, and the sensation of him brushing against her inner walls sent waves of pleasure through her.
"You feel so good, Marina," he growled, his voice hoarse with desire. "So tight and wet."
God, it sent shivers of pleasure through her, knowing that she pleased him. He began to move, his hips thrusting in a steady rhythm. Each stroke sent ripples of pleasure through Marina's body, building an intense heat within her. She clung to him, her fingernails digging into his broad shoulders as she met his powerful thrusts. Her huge chest was trapped between them, and Charlie’s deft hands made quick work of her bra. It floated away and her bare nipples crushed against his chest for a moment before Charlie pulled back, still undulating his tail and plunging into her.
Charlie's hands roamed over her body, squeezing and caressing her breasts, pinching her nipples until they hardened into peaks. His fingers trailed down her stomach, teasing the sensitive skin just above her tail.
"Oh, Charlie!" Marina cried out, her body arching off the coral bed as he touched her in all the right places. "Yes, right there!"
He chuckled, a deep and sensual sound, as he continued to pleasure her.
"You like that, don't you, my little mermaid?”
Marina could only moan in response, her words lost in the wave of pleasure crashing over her. Charlie's words were like a spell, stirring her passions and awakening her true nature. His mermaid, yes, she was all his, that was all she ever wanted to be.
Charlie increased the pace, his tail flexing with each powerful thrust, driving his cock even deeper inside her. Marina's body trembled on the edge of release, every nerve ending alive with sensation.
"Cum for me, Marina," Charlie commanded, his voice thick with desire. "Let go and feel it all."
His words were the final push she needed. With a cry of abandon, Marina's orgasm exploded through her, rippling along her tail and up her spine. Her pussy clenched around Charlie's cock, milking him as wave after wave of pleasure washed over her. Charlie growled, his own release building as he felt her climax. With a final, powerful thrust, he buried himself deep inside her, his cock pulsing. They lay entangled, their tails intertwined, as their breathing slowly returned to normal. Marina nestled against Charlie's chest, feeling his heartbeat in time with hers.
"You're even more incredible than I imagined," Marina whispered. “I couldn't deny it any longer. God, I wasted so much time being stubborn.”
“That’s what I’ve been trying to tell you.” Charlie chuckled as he snuggled closer. “But that’s okay, we still have the better part of the semester to make the most of.”
~
“You’re sure about this?” Harriet asked as they floated outside the embassy doors. “Finishing your whole degree here?”
“Positive.” Marina grinned. “Charlie is staying too, it’s not like I’ll be on my own.”
She snuggled into Charlie’s side for emphasis and he gave her shoulder a squeeze.
“I never would have guessed you would be the one to stay.” Jamie said. “Being a mermaid has been fun, but I am ready to get back to having two legs, a dick and playing baseball.”
“It’s going to take some time to get used to being a guy again.” Harriet chuckled.
The idea made Maerina shudder. She was so happy here in Atlantis as a woman she never wanted to go back to the surface especially while Charlie was staying with her.
“Don’t worry guys, I’l take care of her.” He nodded. “And I finish my degree this semester, I already have a job lined up at the research institute.”
The bell above the door rang, and a red light lit up, signalling that the decompression chamber was ready. The four friends looked at each other with bittersweet smiles.
“We’re gonna miss you so much.” Jamie sighed. “We’ll come back for a holiday sometime!”
They all hugged, and Marina watched as Harriet and Jamie disappeared into the chamber. She didn't envy their long, boring trip to the surface or their transformation back into men.
“Are you sure about this?” Charlie asked a moment later. “There is still time to change your mind.
“Didn’t you hear me? I am totally sure.”
And she was. There wasn't a single doubt in her mind that this was where she belonged—in her new body, her new home, with her new love.
“Come on!” she called, flicking her tail and curling Charlie with a playful grin. “Race you back to the dorm. We have just enough time before class for a little fun.”
Charlie chuckled and gave her a playful peck on the nose, only for Marina to surge forward and press their lips together passionately. Her body melted against his, and once again, she smiled, thinking about how foolish she had been to resist this. She didn't know what the future held for her down here in Atlantis, but she knew that with Charlie at her side, she could do anything.

Can they change sex more then once?
The Spiralled Eye
it goes both ways, but its much more common for males to become females thanks to the gender ratio
Rat matt
Are males the only ones that can change sex or can females change into males? Like if there is a group of females will one of the become a male?
The Spiralled Eye
I've never published to ao3. And the sequel is still to be written.
Blondemystique
Idk, maybe on archiveofourown? and i do love your stories! Im sorry if this sounds crazy but just curious... does charlie begin to change female next with marina for another male?
The Spiralled Eye
