(Male to Female / Female to Pool Toy)

“Hello, welcome to Magic Waters, The largest and the most magical water park in the world where all your aquatic fantasies come true! I’m sorry, but we won’t be open for another few hours.” A young woman wearing a shirt with a logo and a wave that spells out MAGIC WATERS on the shirt was too small for her breasts and she threatened to tear the shirt in half. But that wasn’t what caught Sam’s eye. It was an orca tail that protruded from her butt and a large fin on her back.

Sam was a tall well-built man just out of college. He brushed his hand through his short black hair. “I’m here for a job interview.”

The girl with the orca tail pointed him over to a desk with another orca girl, and said with a smile, “That’s amazing! I hope you get the job, you will love it here!”

Sam talked to the orca at the desk who brought him into another room, to wait for his interview. On the way there they passed by countless girls with tails and fins, a few had furry arms and legs like otters, a woman whose legs were tentacles restocked a store, and a dozen or more short girls who looked like they had the bodies of penguins dressed as waiters. In the waiting room sat a woman, she was the most normal woman that Sam had seen since he had arrived. She had short blond hair and was wearing a simple shirt and pants.

She looked up from her magazine, “I didn’t expect anyone else to be interviewing today. My name’s Melody.”

“I’m Sam, nice to meet you.”

“Likewise. And Sam what are you signing up for?”

“Oh, I going to be working as a lifeguard.”

“That sounds fun.”

The door opens and an older sharp-dressed woman enters the room. She was dressed in a professional suit and skirt. Like the other woman, he saw her breasts look like they were about to burst each of the buttons of her shirt, and like the other girl’s Sam’s eyes were drawn to other parts of her. Her arms ended in a pair of stumps, but that didn’t seem to inconvenience her as in place of her legs were eight long tentacles that she used as hands. “Hello, Miss. Reid and Mr. Clark,” she says as she extends one of her tentacles to the two and shakes their hands with them.

“It’s a pleasure to meet you, Miss. Kraken, I loved watching your performances when I was a little girl,” Melody exclaims as she eagerly shakes the woman’s tentacle.

“I always a pleasure to meet my fans, and just call me Karen. As in Karen the Kraken. I may be old, but I’m still as playful and energetic as ever.” The squid woman says, she looks at Sam and says with a smile. “And it’s a pleasure, to have a state champ swimmer working here.” She pulls the two of them close to her, hugging them with her tentacles. She hands them paper and pens. “All you two have to do is sign here and we can get you in uniforms then we can begin orientation.” The two sign the papers without hesitation and then hand them back to the woman. “Now that’s settled will you two follow me?”

The three walk through the back rooms and maintenance halls of the building. The placing is a winding maze comparable to the tunnels under Disney Land. The three-stop at a large door labeled Changing Room. Karen opens the door to the changing room and two octopus women wait for them. The two seem to be identical twins with similar armless tentacle-legged bodies to Karen, the only thing telling the two apart was that part of their hair was covering their eyes on either the left or right., being a mirror image of each other.

“Meet Sliva and Skyler,” Karen says pointing at the two twin octopus women.

“I’m Sliva,” the one on the right with her hair covering her right eye says.

And, I’m Skyler,” the other woman says.

“Well, I will leave you two with these fine women and fetch you two have finished changing,” Karen says as she leaves the room.

After the squid woman left the twins turned to Sam and Melody. They flash a devilish grin at each other. Sliva speaks first, “Looks like I will be in charge of you big boy.”

“And you're mine,” Skyler says wrapping her tentacles around Melody tightly. She picks up the woman with her tentacles and uses the remaining to rush into another room locking the door behind her.

“Well, shall we get started, as well?” Sliva says to Sam. Sam nods in response. “Alright then follow me.” The two enter their separate room. The room was more akin to a doctor’s office crossed with a beauty salon. “Alright strip and place your clothes in this bin.”

Sam does as instructed striping out of all of his clothing and discarding them in a bin. He was a bit embarrassed from being naked in front of the busty octopus woman and his erection wasn’t helping him. Or the fact that she was staring down his muscular body.

“Oh, looks like I choose a hunk to work my magic on,” she says with a smile as her tentacles grab various bottles of liquid out of the numerous cabinets around the room. “Alright big boy lay here,” she says placing one of her tentacles on a cushioned bed-like table. Sam does as he is told laying flat on the table. “Alright, any requests?”

“Yeah, I kinda wanted to keep my muscles. I worked hard on them and don’t want to lose them and besides my girlfriend likes them,” Sam says nervously as the octopus woman looms over him, knowing that he has given all control to her. “You know like a tomboy?”

“With a body like that, I can understand why your new look similar to your current one,” Sliva says as he pulls out a container of gel. “Open wide.”

Sam opens his mouth as wide as he can when suddenly one of Sliva’s tentacles covered in the purple gel plunges into his mouth. The tentacle goes deeper and deeper reaching all the way back to his throat. Once reaching its destination it swills around covering it with the gel. Once Sam’s throat was fully covered the tentacle was removed causing him to gag.

“What… was… that… for…?” Sam was trying to catch his breath. He coves his mouth his a girly gasp. His voice was different, it was higher sounding like that of a woman’s. It was noticeably higher but still sounded someone masculine as it was deeper sounding more like a stereotypical tomboy. “Wow, I sound different. I like it, I sound tough yet feminine,” he says testing out his new voice becoming rather fond of it.

“Alright, now onto the next part,” Sliva says as she wraps a tentacle around Sam and lifts him into the air causing him to let out a girly squeal from the sudden lift. Silva grabs what looks like a shampoo bottle and squirts it into one of her tentacles. She rubs the deep red liquid into Sam’s hair causing it to be covered in a layer of thick red bubbles. She runs her tentacles through the screen of bubbles. Sam could feel his hair get lighter, softer, and longer. Sliva stopped when the layer of bubbles reached down below Sam’s neck She carried him over to a large skin, where she held him under it. The water washed off the bubbles revealing beautiful shiny red hair that looked more like a wig on him due to its color being very unnatural and plasticy. Sliva brought him back to the table where she laid him back down. Sam ran his hand through his roughly cut red feminine hair.

“This might tingle a bit, but try to remain as still as possible, got that big boy?” Sliva says as she covers two of her tentacles in another pink gel. Sam nods in confirmation. “You are going to be out for about an hour, your body is going to feel strange like it’s being poked and pushed all over the place,” Sliva starts to spread the pink gel across Sam’s body starting at his legs and turning him upside down to get her back. Sam shives as the cold gel sticks to his body as if it were paint that dried on him. Sliva closes Sam’s eyes as she starts to apply the gel to his head. Like the woman said he started to drift off to sleep.

Sam woke up in a pitch-black empty room. He looked around until he noticed a mirror on the wall. He smiled as he brought his hand through her new hair. It didn’t fit with his old body but on his new muscular tomboy, it would fit perfectly. While looking in the mirror he notices something strange with his feet, they looked dainty. It spread up his legs removing all of his leg hairs as well as making them daintier as well, but still having noticeable muscles. His hips flared out becoming thick with fat. His butt ballooned out becoming two round spheres. Sam rubbed his large round fatted ass, feeling the pleasure as it jiggled. His attention was drawn away from his bubble butt when he felt his penis tugging. He wraps his hands around his erect penis it starts to shrink. It gets smaller and smaller in his hands until it the tip reaches his crouch and folds into a vagina as he cums out of his new female sex. Sam’s large muscular hand sank into his soft fleshy folds. The changes spread to his torso causing him to become skinner but keeping most of his muscle. His nipples start to become hyper-sensitive as they start to rise. He cups them as they start to become hills and bloom into a pair of double G mountains. Sam moans as he cups his new pair of breasts grouping them as he squeezes them with his muscular hand. As he plays with his new breasts his hands become smaller as they and the rest of his arms lose muscle. Sam gasps in shock and closes his eyes tightly as his face starts to tingle. He could feel his face shifting as it became softer and his lips puffed up. Sam held his new body tightly as he squealed in delight from the changes.

“Sammy? Sammy? Are you there Sammy?” a voice says waking him up.

“What?” she says groggily.

“How was your dream you looked like, you were enjoying yourself?” Sliva says with a smile while running a tentacle over Sma’s breast.

Sam jumped up from the table and stared at a large mirror in the room. The once muscular man was now a sexy curvy bodybuilder. Her muscles were notable enough to still make her look feminine, but also make her look tough. She grinned as she posed in front of her mirror. “I feel powerful and sexy,”

“I’m glad you like your new body, Sammy,” Sliva says with a smile,” But we aren’t done yet.”

“Hell yeah, I love this body. I feel like I could double my fasted time in the pool and turn heads in the process!” She loudly exclaimed laughing. New thoughts filled her mind, as she became more competitive in sports as well as everything else including looks. “Whatever is next I can take it!”

“Calm down killer,” Sliva says with a giggle. She pulls out a red shark-shaped gummy from a bottle filled with other shark gummies. “All you need to do is take this.”

“A gummy?” She says with a shrug, before gulping it down with one bite. The area around her shoulder blades and above her butt starts to get stiff. “Why are my shoulders stiff all of a sudden?” she says as she rubs them.

“With breasts that big you will get used to it,” Sliva says pushing up Sam’s large breasts. “But this time it’s different.”

“Different? What do you mean- AGH!” Sam was interrupted by a girly squeal as red shark fin and talk popped out of her back and butt. Sam flicks her new tail around until it lands in her arms feeling its large form. “Man, I have a tail sick!”

“It looks good on you Sammy,” Sliva says as she turns to a closet.

“Hell Yeah, it does!” she loudly shouts. “And please don’t call me Sammy

“Ok then. Time, for you to get dressed,” Sliva says pulling out a red lifeguard uniform with the words “Safty Shark printed on it.

Sam slips on a swimsuit slipping her tail and fin into respective holes. Her breasts and ass tightly strain against the sink-tight suit and tie her hair into a ponytail. “Isn’t it a bit small for me, do you have any bigger ones?” Sam notices a hole in the swimsuit’s chest right where her belly button is. “Is this hole supposed to be here?”

“Don’t worry dear, it will fit perfectly in a minute. And yes, you will find out later,” Sliva says poking the girl’s breasts. “Now come with me we are almost done.”

Sliva leads Sam back out of the room. Upon entering the room the other door opens and Skyler brings out a woman in a wheelchair. The woman’s hand had long wavy sapphire hair, and her breasts were comparable to her own that strained a tight sapphire bikini top, but the strangest part was that in place of her legs was a long fishtail with sapphire scales. It took a second for Sam to realize who she was, it was Melody. Like her, she had gone through her own changes. Where she was a plain boring girl previously but now she was a sexy mermaid.

“Sam! Is that you?” she says in a song-like voice.

“Damn, looks like you went through some major changes too,” Sam says putting her hands on her hips admiring the half-fish woman.

“Not as much as you have,” she giggles back her eyes glued to the tomboy’s muscular body and breasts.

“Alright girls you can talk later, we need to finish and get the two of you on your way,” Sliva says as she grabs two large cans of air from a closet.

Skyler pulls two small boxes and a can out behind her back and exclaims, “Alright who wants to go first?”

Sam and Melody look at each other before Melody quickly raises her hand, and quickly exclaims, “ME! I want to go first!”

“Someone’s excited,” Sliva says as she elbows her twin with her tentacle.

“Best not keep her waiting, right honey?” Skyler says as she uncaps the can. She approaches her mermaid and dabs her tentacle in the can getting clear goo on it. She then rubs the goo on the area around Meldoy’s bell button. Melody giggles from the cold tickle of the woman’s tentacle rubbing her chest. “This is going to feel strange for a minute,” the woman says as she opens the box. Inside the box is a white plastic nozzle like any you would see on an inflatable. Skyler sticks the nozzle onto Melody’s chest, it sticks into place. Melody shifts in her chair as she grunts and the plastic merges seamlessly with her skin. She poked at the plastic that was now firmly attached to her chest in place of her belly button shivering from each touch.

“What happens, if I open it?” she asks prodding at the cap.

“You’ll deflate,” Skyla says casually. Melody gasps in fear instantly pulling her hand away from the plug. Sensing the girl’s fear, Skyla smiles and says,” Don’t worry all you need is someone to blow you up again. Trust me having someone blow you up is the best feeling in the world.”

“Ok then,” Melody says trying to imagine what it would feel like to be deflated and reinflated. Skyla suddenly yanks her plug open, causing air to flow out of her. Melody’s body starts to sag as her body deflates like a balloon, her movements slow to a crawl as she starts to sink into herself. She brings her deflating arm into her vision as it becomes flaccid as the air rushes out of it. Her breasts sagged like a pair of deflated balloons that were attached to her chest. Her head shoots back as she moans loudly as the last of her air left her body. Her body sat in the chair looking like a deflated blow-up doll. Her eyes were the only part of her that was still able to move as they darted around the room.

Skyla lifts her deflated head and smiles, “What you were curious?”

Melody tiredly gasps as a long tube is shoved into her nozzle plugging the hole and preventing the rest of her air from leaving. Skyla flips a switch on the tank of air that the tube is connected to. The sound of hissing fills the room. A plastic sheen spreads out from the nozzle as her belly starts to rise. The plastic sheen spreads around her body. When it reached her bikini it seemed to merge with her skin looking like it was printed on her plastic skin. The same thing happened with the scales on her tail becoming printed on details. The plastic spread up her arms, and when she reached her hands her fingers merged becoming mittens with her fingers drawn on. Melody could only watch as the plastic spread up her neck and reached her turning her face into a printed-on detail making her face look less human and more anime-like. She moved her eyes and mouth causing the printed detail to animate as she did. It spread to her hair turning into a separate solid piece of plastic. Her body began to inflate more and more regaining a more human figure. She gasped as her breasts ballooned out becoming as large as beach balls. Movement returned to her arms as they became fully inflated. Her beach ball breasts squeaked as she felt them with her mitten-like hands. Seams form up her sides and connect her limbs and as well as breasts to her plastic body. And shortly after her body was fully inflated. She was larger than before in more ways than one. Any sharp edges of her body were smoothed into curves.

“I feel so light…” she says, her printed-on mouth moving like normal. “I feel so free and energetic,” She gleefully her immobile form barely able to contain herself in the wheelchair threatening to topple it over.

“Save it for the water,” Skyla says as she pulls out the tube and caps Melody’s nozzle.

“It’s your turn, Sammy,” Sliva says with a devilish grin. She pulls her close with her tentacles using the remaining ones to apply the goo and stick the nozzle on in the hole of her swimsuit. Sammy tries to hide the discomfort of the nozzle fusing with his skin. And with a pop, it merged with her skin. “Are you ready for what’s going to happen next?”

“As ready as I will ever be!” she shouts as she uncaps her nozzle with a wide toothy grin. The feeling of the cool air rushing out of her turned her on as if she were relieving herself causing her to let out a faint girly moan. But that feeling was cut short was the tube was stuck into the hole. Sliva turns the air on and a rush of hot air flows into her. Sammy felt her stomach start to bloat as her swimsuit merged with her plastic skin that was spreading out from the nozzle. Her body became rounder as her muscles flattened out into her body and became drawn on. She ran her hand over her drawn-on six-pack squealing as her skin rubbed across it. A shot of pleasure pulsed through her as the plastic spread downwards merging everything including her pussy into the bottom of her swimsuit. She rubs her hand down where her pussy used to be squeaking as it was as pleasurable as before. Her butt ballooned outwards becoming larger. Her legs followed suit becoming thicker and curvier with her muscles being drawn on. Her toes merged becoming a single mass with drawn lines representing them. As the plastic spread down her tail it became a large balloon mass that squeaked against the ground as it rubbed its large mass against it. With a loud pop, her breasts exploded out becoming two large beach balls. She cupped her breast the best she could her fingers sinking out the plastic balls they became causing her to moan. Her fin bloated becoming wider and rounder. Like her legs, Sammy’s arms become smoother and rounder with her muscles becoming drawn on, and her hands becoming plastic mittens. The plastic spread up her head, she smiled widely as her face became a drawing. Her hair followed becoming a solid balloon ponytail. Out of her hips and shoulders, solid plastic handles form. Sammy rubbed her new plastic body squealing as she did, she was now a human pool toy and it felt wonderful.

“I feel so light and free!” she exclaims joying into the air much higher than she could do before due to her air-filled body, “I feel like I could swim for days without taking a break! Can I get into the water?”

“Someone’s excited, isn’t she?” The voice of Karen rings out as she enters the room. Her newly plastic body squealed against the floor. Like the other two girls, she was also a living pool toy. Her clothes which looked like they were about to explode, now tightly clung to her more curvy and larger body as they were now a part of it. “Ok, girls now that you are in uniform it’s time for your orientation. But first any questions?” Sammy eagerly raises her hand. “Yes, dear?”

“Why are our breasts so big, I feel like they would get in the way only to help keep us on the surface?” she asks.

“Due to your new magic bodies, your floatiness only applies when you want it to, so you can skin and float whenever you want. And the breasts help you carry even the heaviest person.” Karen explains.

“Makes sense…” Sammy laughed believing that there were other reasons why they were so big, but she didn’t mind much. She raises her hand again, “Also-”

“No, you can’t get popped, or break in anyway,” Karen says correctly guessing what she was going to ask. “Also with just a thought you can change back and forth from being rubber to flesh, but the tail and fins stay,” she says once again predicting Sammy’s next question, as well as switching between plastic and flesh to demonstrate. “It might take some getting used to, but you will get the hang of it.” With a smile, she says “If you two don’t have any more questions we should get going.”

Two inflatable orca girls enter the room. One of them tells Sammy to follow her and the other chats with Melody as she pushes her out. The two newly inflated girls say their goodbyes as they head their separate ways. As Sammy walked she felt a lightness with her steps almost bouncing off the ground. She liked the light calming feeling as it made her at ease. After a while of walking the two reached the lifeguard office. Inside there were countless girls who were all inflatable sharks like Sammy but varied in color. Some looked like they had drawn on muscles like her and others looked like any hot lifeguard you would see on TV. They were all friendly and welcoming to her asking to race her or to have diving and other water-related challenges. Sammy knew she would fit in just fine. The head lifeguard had to break up her welcome party so they could get to work. Sam passed every test with flying colors, she swam faster, further, and longer than ever before. The other girls congratulated her as tomorrow she would begin working as a lifeguard. She spent the rest of the afternoon drifting in the pool without a care in the world until closing time. After helping the other girls clean up she changed back into a human shark girl. Although she missed the light and free feeling of being an inflatable it was probably for the best to head home as a human. She was provided a company tee shirt, a pair of shorts, and sandals as the clothes she wore here wouldn’t fit her anymore. The shirt could barely fit over her breasts and the shorts were too tight to the point she couldn’t button them. The other girls joked with her about her ill-fitting clothing and reminisced about the same thing happening with them.

After saying her goodbyes to her new friends and co-workers she left. On her way out she was walking alongside a pool when she was suddenly drenched by water. Her wet shirt became almost transparent as it clung even tighter to her breasts. She looked over angrily at the water to find Melody in her regular playfully giggling at her. After seeing her Sam’s faded and she joined in with her mermaid’s laughter.

“Heading home to Melody?” Sammy asks, “Is someone going to pick you up or something? It must be hard without your legs right?”

Melody giggles, “This place is my home now.” she swims up to the fake shore and lays down on her breasts, “The other girls and I, along with other less mobile people live here.”

“I didn’t know this place had apartments?” Sammy says as she curiously scratches her head.

“Yep, underwater ones!” Melody cheers. “Well more like Underwater dorms.”

“You live underwater?” Sammy questions.

“Yep, the other girls told me that it’s relaxing I can’t wait to sleep like a fish,” she says resting her head in her arms and thinking about what it would be like. “Well, I have to get going, the girls are having a welcome party for me, see you around Sammy the Shark.”

“See you around Melody Mermaid,” Sammy says with a smile. “I have to check out one of your shows when I’m on break the other girls told me that the Mermaid Theater is one of the best attractions here.”

“I remember coming here as a kid and seeing it for the first time. I was so taken away that I knew I wanted to become a part of it,” Melody says reminiscing about her first visit spacing out. “And look at me now!”

“If it’s as good as you make it sound then I have to check it out,” Sammy grinned

A voice calls out to Melody. The two turn and see a group of mermaids waving her down. “Well, I have to get going, See you tomorrow, Sammy.”

“Same here,” she says with a sigh, “My girlfriend is dying to see my new look. It’s all she has been talking about for the past week.

The two say their goodbyes as they part ways. Melody swims off to the group of fellow mermaids and Sam walks towards the exit accidentally turning back into a pool toy thinking about tomorrow's work and her new life as a shark pool toy lifeguard.
