#21 of Transformation: Gender shifting

Avinete's helping someone get their real shape. Even if that's into a curvy mare


He sighed to himself as he looked in the mirror. Sam was getting nowhere fast! While he was toning down, he wasn't getting those muscles he wanted so badly. He could hire a trainer, but that was an expense he wasn't sure he wanted! They were so costly... even if they were nice to look at. He couldn't help but grin whenever he saw one of the gals, a cute girl... nice and tone. A part of him wanted that. But in what way? He wasn't too sure.

But she shook those thoughts out of his mind as he looked in the mirror. Sam smirked. He could get stronger. "Yaah, just watch me. In no time at all people will be staring at me!"

"You got that!" he heard a girl's voice behind him. Sam looked in the mirror and saw a curvy alluring girl standing behind him. She was a mare! And she was staring right at Sam

"W,who are you?" He was so flustered at the girl talking to him. She was quite a sight in a black tight pants and a pink top, her body toned and fit. She stared at him and smiled warm as a dear friend.

"Why I'm Avinete, I'm here to get you into shape!" She spoke out to him. Sam would notice the other people in the gym stopped paying attention to them. How could they miss this girl?! Avinete leaned forward, looking at him even closer.

Sam could feel something wrong in those eyes. She was glowing with a pink energy as she looked at the human. The man couldn't move anymore. He struggled away from the mirror, feeling panic grow inside him. What was she doing?!

He cursed as he struggled. Avinete giggled at his attempts.

"Oh don't be so stressed! I'm helping you out get big and buff just like you wanted! Of course... with a few extra modifications. A big boring buff guy? SO lame. You need to be a big girl showing off your curves and body."

And he could feel it as she spoke. The man squealed as his flabby arms swelled in size! He could feel the firm muscles growing in. His body losing its softness to a tight definition. But it wasn't the masculine strength he was expecting, he could *feel* it was so alien! It was was changing oto. Those muscular pecs he had were pushing out. He let out a gasp at their sensitive form.

He couldn't help but reach up to grope it, feeling his fur squishing against it.

"This... this" Sam struggled to say. Avinete reached forward and wrapped her arms around him. Her large boobs squished against his. It was an intense, pleasurable thing that left his body feeling warmth from it. It left a flush on his cheeks,. It was too much!

"You're going to LOVE it. Being a cute gal... you'll help so many gals get into shape! Knowing they're going to be staring at your sweet body"

Indeed, the idea was starting to sound hot to him as his body continued to change. He could feel his hips pushing out while his waist shrunk in size. His... her stomach felt so taught, her entire body was getting so slender and powerful!

Avinete was getting bolder, her hands reached around the changing horse to squeeze her still small ass. But that quickly changed against her feminine hands. Soon those cheeks swelled in size, Sam blushed furiously as she felt her ass tone and swell with fat. It snug tightly against her pants... was it just her, or were her clothes off as well?

Something was filling her view as well! She could feel it pressing against her nose. It was swelling out, the thing was turning the colour of her new fur. She snorted, feeling her new nostrils working breathing in great gulps of air. She let out a whinny and heard her new voice. Everything felt so off! She could feel her lips swelling in size, growing plush and plump.

She looked down her equine snout at her clothe

And was shocked to see what was a tight pink top holding her boobs. She was sporting a hefty cleavage, and she could feel their weight! They were squished against Avinete as Avinete squeezed her new rear. She was wearing a tight pair of black shorts, one that made her blush. She could feel her thick thighs, her huge butt... her pussy getting so hot and bothered by the mare's advances. Avinete knew it too.

She reached forward and kissed the new mare's mouth. Sam couldn't handle it, she let her in. She blushed as Avinete pressed deeper, the two mares embracing. Avinete's hands explored Sam's new body. *It felt so good... but she used to be a guy. All these feelings felt so wrong... but Avinete knew just how to tease her.

Avinete's hands brushed against her tail, it made an involuntary flick. It tickled against the fabric of her pants, she could feel it's fine hairs beneath her clothes.

But something else was changing. Avinete was making it so. They were pushed into a different part of the gym. Sam was staring into the mare's yes, unaware as they were pushed into the girl's section of the gym. In there, a new name was scrawled onto the personal coaches.

Samantha Nickers, with a picture of her new body. A cute smiling mare posing for her shot. The world was slowly coming back to motion, around them the other users were becoming all too aware of the intimate display before them. Some of the girls looked at Avinete with a hint of need and jealousy. They've felt her embrace before.

Avinete pulled away from Samantha. "See? Isn't that so much better? Look how you're in shape!" She waved a hand at Samantha's body.

Samantha looked down, she could feel it. Her body was toned, event though it was a girl's body! She could feel her huge ass squished against those pants, or the weight of her boobs against her bra.

"I...I" She didn't know what to say.

"No need to thank me." Avinete interrupted her and giggled. "You have a whole lot of people to train!"

Samantha blinked at that. What on earth did she mean-

"Hey Samantha, are we ready to work today?" She heard a voice behind her. The mare turned around to see a chubby cow staring at her with a nervous look. Albree, riiiiight, her thoughts spoke for her. She remembered when she first saw the cow- wait, why did she remember that? She never saw this cow-

"Yeah Albree, let's get to work!"
