Welcome to Swim Club (AP + F2M TG, some AR)

A mother and her son are forged into men as they become the newest members of their school's senior swim team.   


“Mom, I can go by myself!” said Sammy.

He got changed as fast as he could, and didn’t stop to wait for her by the showers. Instead Sammy went straight to the main pool. Best to get it over with, he thought, and dived head-first into the deep end.

The shock of cold water was unbearable, but he tried to keep himself warm by swimming, with his best attempt at a butterfly stroke, not knowing all the while that he was being watched.

When he got to the other side, he saw the competitive swimmers in the roped-off area of the pool. There was a guy in a swimming cap who looked about his age, swimming lengths and looking serious. He would probably be going to Sammy’s new school.

Determined to prove himself the better swimmer, Sammy pushed off the nearest wall and tried to out-swim the other kid. But after two lengths, he was already tired. He noticed his mom watching from the stands. What was she doing that for?

Suddenly conscious that he had an audience, Sammy pushed off the wall again, determined for one last show of strength. It was exhausting though, and maybe someday he’d get stronger and win all the swimming races, but for all his best efforts, he was losing. The other boy was already half the pool ahead of him.

Sammy punched the water in his disgrace.

He saw his mother walk towards the pool, her body practically hanging out of the costume. But instead of jumping in, she crouched down to talk to one of the swimmers. Uh oh, this could be embarrassing. She was not going to go talk about joining the swim club without him! So he got out the pool, shook out his hair, and walked over to Mom.

One of the older swimmers had already swum out to meet her. He looked like maybe he was their coach, but when he got closer Sammy realised it was one of the senior students.

“Hi, I was just watching you swim,” Mom said to the stranger. “And I’m wondering if maybe my son could join one of your teams?”

Even though he was still in the water, he seemed to tower over her.

“Alright...” he said, popping his goggles over his forehead. “What grade is he in?”

“Sammy’s just turned fourteen,” said Mom. “And he’ll be joining the high school this September.”

“Well it all depends on how willing he is to make the commitment, training sessions every Friday, et cetera. What’s your name by the way?”

“I’m Erin,”

“Erin,” he said. “And I’m Shaun. Is this your son?”

“Hi...” Sammy said, poking his head out from behind Mom. “So I guess I’m Sammy.”

He reached down to shake hands in Shaun’s tight grip. Sammy almost felt a little shiver run through him. Or was that the cold?

“So Sammy, d’you have a gym membership?”

“Nah, it’s kinda my first time here.”

“You’ll need one,” said Shaun. “To stay in shape, I mean. And what about you?” He asked Mom.

“Oh, I’m fine to take him on Fridays,” she said.

“Mom! We live like, two blocks away.”

“I know,” she replied. “But I still need to show up and give you moral support.”

“Okay, then you’ll need one too,” said Shaun.

“Me? A gym membership?”

“Yeah. I usually find the best kind of moral support is when it comes from a fellow athlete.”

“Would you like that too, Sammy?” she said. “We can be work-out buddies!”

Sammy had never looked more embarrassed.

“I’ll join the junior team okay, just as long as I don’t have to go to the gym with my mother!”

“There aren’t actually any places on the junior team right now,” said Shaun. Sammy looked at him dejected, but he continued: “We have however had two people leave the senior team just recently. So there are spots opening up. Just to let you know, we compete at a semi-professional level. Is that something you’d like to get into?”

“Yeah!” Sammy said enthusiastically.

“Wait a minute. Are you sure he’s ready for the senior team?” said Erin.

“Mom!”

“You will be,” Shaun said with a smile.

Sammy replied with an even bigger grin. But Erin still looked unsure.

“Tell you what,” said Shaun. “I’ll ask Tyler.” And he called out, “Hey Ty! Does this look like senior team material to you?”

Another with a swimming cap in the school colors that had the words Team Captain swam over, gracefully as a dolphin. Water cascaded from his streamlined torso as he heaved himself over the edge of the pool

“Hi,” he said, drawing himself up to full height. “What’s your name, dude?”

“Hey, Sammy,”

“And I’m Erin, pleased to meet you,” said Mom, then Tyler turned back to her son.

“So, Sammy,” he said. “I saw your swim technique. And d’you know what, I think you’re almost ready to move up to the big leagues. You would be most welcome to join our team.”

“Awesome!” said Sammy.

Tyler leaned down to shake Sammy’s hand, then he shook Mom’s.

He definitely noticed it that time, like a shivering sensation that ran from head to toe.

Erin didn’t notice anything; she was far too preoccupied by the relief of having gotten Sammy into a team. After so much time spent searching for schools, it had all been so easy, nothing like the time trials at Sammy’s previous school. She would remember that for next time: all you have to do is ask.

“Excellent, that should fill up the remaining two places,” said Tyler.

“Ah man, this is awesome...”

“Wait, did you say two places?” Erin asked, but she was immediately distracted when she looked back at Sammy, for which she had to stifle a gasp. His body was changing at a most alarming rate. He was becoming lean and taller, muscular and more athletic. It nearly broke her heart to see, but there was no denying it now; her baby was growing up into a champion!

“Sammy?”

But Sammy was in his own world now, relaxing into his new growing body, quietly thrilled by the change in size and loving every moment. With each slow breath, he was putting on muscle mass, building up his chest and acquiring the broad shoulders of manhood.

“Whoa... I’m getting bigger.”

And indeed he was. They always said that Sammy would be a late developer, but now he had finally achieved the dream of growing tall like his father, maybe even an inch or two taller.

Soon the last of his puppy fat was gone, and the flat stomach had become a finely crafted six-pack. His chest too was a powerhouse of subtle strength. And his legs had changed from skinny boy’s legs into great pillars of masculine might, which were just now beginning to sprout hair. Before much longer, some fluff had sprung up on his chest and underarms, as the changes to his body approached completion. No longer was it the body of a child, but the streamlined figure of a swimmer. The last part of him to change was the hair on his head, growing just a shade or two darker, with a few soft spikes at the fringe,

Just when it seemed that the transformation was over, Sammy’s dolphin-print swim shorts, the ones he’d worn since he was ten, melted and reshaped themselves into a sleek new pair of navy blue trunks, stretching snugly around the contour of his groin.

“You okay, Mom?” he asked, his voice now deeper than before. And when he turned back to face her, she had to hold back tears.

There was still the same cheeky, childlike grin that she loved, same dimpled face and button nose. But everything else about him was so much more... mature. He’d really grown into himself lately, especially since joining the swim club, and it was wonderful to see her sweetheart looking so confident. He’d matured so much in a few short months that he no longer looked like a boy starting high school; he was almost as big as the two seniors.

“Nothing. I love you is all,” she managed to say, and planted a kiss on his shoulder. But before Erin could say another word, something else took her breath away. It welled up from deep inside her. Erin’s heart was racing, and she felt a warm flush; it was happening to her too.

It felt like she was floating away. As Erin began to change, a great weight lifted itself from her shoulders. And she realised that her thick layer of body fat was disappearing. Without its burden to weigh her down, she stood up taller, prouder than before. The rotund figure given to her by fourteen years of motherhood was finally fading away, or turning into something altogether more powerful.

“Is this really happening?” she murmured.

Every inch of her skin felt trim and tighter, from her face to her butt, to the tips of her toes. Her navel drew itself inwards, pushing away the flab of her belly, as did her hips. And she momentarily had the sensation of being very top-heavy, which she realised was due in part to her rapidly lengthening legs.

Her top half was changing shape too. As the one-piece swimsuit fell away from her shoulders and shrank into a tight green speedo, the exposed mass of her bust redistributed itself, turning into muscle as it did so.

Soon it was a firmly toned chest, just like her son’s. Her back straightened, and her legs continued to grow. In a moment she found herself six inches taller than before, and just a little off-balance. She put a hand on Sammy’s shoulder to steady herself, and saw that it too had changed. They had become big hands, like Sammy’s, strong yet gentle.

Her arms too had filled out to match the trim physique of her chest and stomach. And what a stomach it was! Every trace of sag and slouch had left her, and she finally had the body she wanted. But it was more than just the physical change; she felt taller. And as soon as she did, she couldn’t go back to feeling any other way.

A small amount of stubble poked out of her now-square jawline. The hair under her swim cap was shifting into its final position. She would have liked to take a good look at her new self when it was all done, and tried to think of an excuse to leave.

When she drew up her shoulders, she felt her private parts slide into an uncomfortable position, and discreetly readjusted her speedo.

“I have to go... powder my nose,” said Erin, in a much deeper voice than she’d expected.

“Sure,” said Shaun. “We’ll start the warmup when you get back.”

Erin felt unusually conscious of her Adam’s apple on her way to the bathroom. There must have been something wrong with the way she walked; it was too meek and ladylike. She tried shifting to a more confident stride, and found that it came quite naturally to her.

For a moment she couldn’t decide on which bathroom to use, then remembered that she hadn’t really needed to pee. So she slipped into the men’s and checked herself out in the mirror. Everything was still there. A quick hand in the trunks just to make sure and... yep, soldiers still in the bunk.

Erin sized up the large handsome guy she’d become, and shot him a flirty smile, then laughed. He couldn’t believe how big he’d gotten in such a short space of time. But then again, he had the best training partner a guy could ask for. He counted himself very lucky that Sammy was also his best friend. But of course, everyone knew that Erin was the more attractive one! He flexed himself once more at the mirror, then headed back to the pool.

Sammy was talking technique with Shaun when Erin came back, strutting the poolside in that bright green speedo of his.

“Alright, you guys ready?” he said, and clapped Sammy on the back.

“I was born ready!” he replied.

“Right then boys, we’ll start the warmup,” Tyler called from the pool. “Erin, Sam, Shaun, let’s give us a solid four laps of freestyle.”

Sammy beamed his trademark boyish grin at Erin, who noticed that his hair was already wet. There was a happy green gleam in Sammy’s eyes and an almost musical quality to his voice.

“Sure! I’ll race ya!”

A transformation story that came into my head one day and wouldn't leave until I wrote it. If you like it, I might do more.

F2M TG is pretty niche, and for that matter so is AP, so please let me know if that's what you like.
