She'd been so proud of herself. Every hour spent training had made her stronger… faster… better than the others on the team. Her trainer hadn't seen the effort she'd put in but the results? He'd seen those. 

At just twelve years old, Saffron was the youngest of her siblings to evolve. She hadn't used a stone to force the change (her trainer had said plenty of times since he'd caught her how he never wanted one of the classic trio) and instead had pushed herself again and again for the sake of being the best she could be for him. 

As the light faded, the newly evolved Sylveon stood tall and proud before her trainer. Her previously flat chest had matured onto a small set of perky breasts and she'd grown a cute little field of pink fur between her thighs as part of a natural bush. She looked up at him expecting to see a sense of joy and pride for her.

All that awaited her though was malice. The young man who's taken her along on his journey for the past eight months scowled at her with a bitter rage that she'd never seen in him. 

"A fucking Sylveon? Really? Why'd you fucking evolve? I wanted an Umbreon. Fucking worthless bitch." He'd brought his leg up before she'd even had a chance to process what he was saying; Saffron doubling over in pain. Another kick followed harder than the first. "God fucking dammit!"

Coughing, Saffron gasped for air as the pain rushed over her. "M… Master, wh-" She was cut off as he kicked her across the face. 

"Shut the fuck up. Goddamit…" He sighed and pulled out his phone, tapping on it. After a few minutes, he put it up to his ear. "Hey, you still looking? Cool, great. Me? Nah, I'm fucking pissed at my stupid as shit Eevee. Yeah. Yup, fucking Sylveon. I'd look gay as fuck… Umbreon. You can? Perfect. Yeah, she's good for that. I don't give a shit. Yeah her stats are good. Awesome, see you soon."

Hanging up the phone, the young man pulled Saffron's ball from his belt. "Fucking waste of my time." He gave another hard kick into the girl's stomach; the Sylveon curling up in a ball. Holding the pokeball up, he tapped the recall and pointed it at her. There was a flash of red light and darkness… the empty isolation that came with being trapped inside a pokeball.

Suspended in that void, Saffron didn't know how much time had passed. She was only aware of the deep seated pain she felt for how her trainer had reacted to what she'd thought was a success. The look of contempt he'd had for her, kicking her again and again… she couldn't understand it. She wasn't an Umbreon, no, but why did that mean she wasn't good enough anymore?

Then it happened. The world around her burst with light once again and she was pulled from the void of her own despair. She'd hoped to see her trainer's face, to apologize to him for being such a failure, but instead she found herself standing in front of a woman in a lab coat. 

Looking down at her, the woman hummed in approval. "Beautiful… simply beautiful, yes. Can you tell me your name please?"

"S… Saffron…" The young girl looked around nervously and took in the sight of what appeared to be a doctor's office. "Where am I?"

"Hello Saffron. My name is Professor Bramble and you're at my research facility. Are you hungry?" The woman walked over to a counter nearby and picked up a tray. Setting it on the ground in front of Saffron, she smiled to her. "Sit please. You'll be on all fours from now on."

Saffron opened her mouth to protest but couldn't find her voice as she obediently sat as commanded. Forced obedience could only be brought about by her Trainer. She felt that pain from before grow worse in her chest as the realization set in. 

"He traded me?" she asked with a sob as she looked up; the tile floor cold against her naked ass. 

"Foolishly, yes… but to my gain. You're going to be a wonderful addition to my research. You're physically perfect and my analysis indicated your statistics to be as close to perfection as I've ever seen." Professor Bramble smiled excitedly. Without warning, she reached out and cupped her hands against each of Saffron's breasts firmly. "Small but firm. I'm confident they'll grow though. Alright, fingers and toes, up up!" 

When Saffron obediently got on all fours, she whined shamefully as those hands moved and felt between her legs. There was no modesty or care of her comfort as the woman rubbed along her spade. "Wh… What are you doing?"

"This is a breeding research facility. I needed to check to see if you were already in heat or needed to be started on injections." Pulling her fingers back, Professor Bramble hummed. "Injections. No matter… Let's get you ready!" 

Moving back to the table, the human picked up a collar and looked to Saffron. "You'll wear this at all times." Moving to her, she clipped it around the Sylveon's throat where it locked with an audible click. "If you try to remove your collar it will hurt you. If you try to leave the building it will hurt you. If you disobey me I will make it hurt you."

Whimpering, Saffron looked up at the woman in confusion. "I… don't want to breed though…"

The woman waved a dismissive hand. "That's unfortunate but your willingness to breed doesn't have an effect on your capability to do so." She hummed. "Come with me Saffron." Moving to leave the room, Professor Bramble held the door open and motioned the Sylveon to follow. 

Reluctantly, Saffron followed on her fingers and toes like she'd been told. She tried to keep her tail tucked but the woman grabbed it as she passed and lifted it high. 

"On display dear. You're not in heat just yet but I expect you to keep yourself on offering for any of the males that want to mount you. They're all given free permission to do so as they wish. You'll let them and you'll bear the eggs that result from it. Once they're done you'll come to me so I can help you deliver the egg and get it in an incubator. It's really quite simple."

Saffron whined and looked up humiliated; the forced obedience brought on by the trainer bond impossible to resist. As the professor led her down the hall, she could hear other voices coming from up ahead. As the human scanned her badge at a door, the Sylveon's embarrassment grew by what awaited her in the next room.

Various eeveelution girls were strapped to padded tables that kept them on all fours with their backsides up in offering. Behind most of them were male eeveelutions actually thrusting into them and fucking them without a care in the world. Where the males looked in bliss the females looked exhausted and miserable. 

One of the males, a Leafeon, looked over curiously as the pair entered. He was currently getting his rather sizable cock licked clean by an Espeon that looked around the same age as Saffron. "New bitch? She free to use?"

"Her name is Saffron," Professor Bramble explained with a warm smile. "She'll be available for breeding momentarily. I just need to get her set up and get her the injections. She arrived a bit too young but nothing we can't fix. Would you like to deflower her Jasper? I don't believe you've gotten to be anyone's first before."

"I'd love to! Thanks Professor!" He smiled bright and gently pushed the Espeon from his dick. Walking over on two legs, he smiles down at Saffron as his cock hung inches from her face. "Hey Saffron! I'm Jasper! You look really beautiful… I've never seen a Sylveon before! Go ahead and give me a suck while the professor gets you ready."

"I… a what?" Saffron whimpered; knowing what he meant but feigning dumb. He seemed genuinely kind sounding and chipper and there was something about his scent that calmed her. In fact, the more she breathed in his sweet aroma the calmer she felt. "A… a suck?"

The Leafeon nodded and put a hand on her head. "Yup! Just open your mouth and start licking my dick. It goes inside you, you know." He gave a playful grin as he pulled her forward gently so his tip was pressing against her lips. 

Whining in protest, Saffron hesitated as she looked up at him. His sweet scent though helped calm her further… she felt a warmth building in her core as every breath was the male's wonderful scent. She wasn't even sure when exactly she'd started licking him until he was suddenly sliding his cock into her mouth. 

She was amazed at how natural it felt… to simply let him guide her in pleasuring him… He was gentle in a way that calmed any concern she'd had. He was warm and strong in ways that spoke to her mind on a primal level. Everything about it felt right to her.

As she suckled that sizable shaft, she heard the Leafeon chuckle. "I don't think she needs the hormone boosters Professor… she's smelling plenty in heat now. Seems her body caught up with her."

"You always did have a mastery of pheromones my good boy. Go on then and give her a mount. Welcome her to the family Jasper." The professor smiled and stepped aside to observe. 

Pulling himself from Saffron's mouth, Jasper pet her gently. "We're going to make some beautiful Eevees together… Alright, stay like that… eyes forward Saffron. Don't move." Moving out of sight begins her, he gently gripped the Sylveon's tail and pulled it up to examine her. "Never seen a fairy cookie before. Smells delicious… alright now… let's see…"

As Jasper's weight suddenly bore down on Saffron, the smaller Sylveon braced herself with a whimper. The sweet scent that had clouded her mind eased away and the anxiety of her situation came rushing back. She felt the Leafeon pulling himself up to properly mount her, her spade dripping arousal for the first time ever, and she could feel the warmth of his body encompassing her. She wasn't ready. She was too young. It was her first heat! He couldn't ju-

Saffron cried out in discomfort as the Leafeon's cock forced into her. Her tight, virgin pussy was forced to stretch around that thick canine girth; her hymen snapping with barely any resistance as the male forced into her. The Sylveon's mouth opened to scream but in a quick motion she found a pokeball being shoved into it like a gag by the professor. 

"No screaming… Just keep that there and bite down on it if needed. If it breaks I'll be very cross with you but I've plenty more to seal you away in when you're not in heat. Only good bitches her outside time."

Whimpering, Saffron nodded fearfully as Jasper pushed fully into her. She'd hoped he'd wait long enough for her to at least adjust to the sheer scope of his size. He might have, in fact, had Professor Bramble not been watching him with as much expectation as she had for Saffron. 

Instead, she was given a painfully rough first time as her body tried to keep up with the feral ravaging it was receiving. His thick cock spread her stretched cookie again and again as he worked his full length into her too tight body. 

Leaning in as he gripped the Sylveon tightly, Jasper nipped her ears and ribbons possessively. "S… sorry…" he whispered just loud enough for her to hear. "I'm trying t… to make it quick… I… I'm about to knot…" He then took her nape in his teeth and snarled savagely as his already rough pace quickened and became more brutal.

She felt it staring to grow… that promised knot. It forced her abused cookie wider and wiser until finally she'd tightened too much for him to be able to rip back out of. It continued to grow as it nested into that special cluster of muscles inside of her specially meant to grip and cradle a knot. As her own body betrayed her, Saffron whimpered as she felt her first ever climax rip through her with blinding potency.

She was only vaguely aware of the warmth flooding into her with each spasm of the Leafeon's cock. Each pulsing eruption emptied more of his seed into the Sylveon's unprotected, fertile core. Her body drank in every drop of the offered cum as her orgasmic contractions served to ensure it reached her waiting womb. 

Saffron collapsed in spent exhaustion as she felt her heart beating terrifyingly fast. Her ears rang an almost deafening pitch and everything around her seemed to move just a noticable bit slower. She was aware of her pokeball being dislodged from her mouth and something else inserted instead; something cold and metal that forced her muzzle to remain open. Her mind barely registered her being picked up, Jasper still on her back and knotted deep inside of her, and she foolishly hoped that meant she'd be taken somewhere to rest. 

Instead, Saffron whimpered weakly as she found herself being rigged up to the of the padded breeding stalls alongside the other female eeveelutions. Her wrists and ankles were forced into restraints, a band was secured to her tail to force it to remain up and out of the way, and a group of males were starting to gather around her. She could feel Jasper's cock still throbbing inside of her as her stomach started to bulge with the egg forming in her womb. 

She'd had her first breeding, was about to have her first egg, and she couldn't help but watch as a line started to form around her. It was her first… and to her dismay… it was only the first of many.
