Day 54 of omnisuit testing. Melissa was doing her rounds at the tavern. She set down today's special, pasta and meatballs for five, on the table. Each person sitting at the table was wearing a simple latex catsuit. A woman with green skin wore blue, the man next to her wore red, the orange-haired catgirl next to him wore black, as did the catboy next to her, and the monkey girl wore green. The five of them took their plates and started grabbing their shares from the large bowl.

Melissa gave them a quick smile before moving on. She watched a man in full black latex, even wearing a tight hood with openings for his eyes and mouth only, leading his slave to an open table. The slave was naked, only wearing a black collar and leash. All over her body were words written in red marker. Most of them were ones Melissa didn't know, but she recognized SLAVE written above the woman's bare chest. The two of them then sat down and looked at their menus. As they weren't ready to order yet, Melissa just offered them water before moving on.

A woman in a black latex cloak and hood sat at the next table holding the menu. However, when Melissa got close, the woman lowered the hood that hid her face.

"What do you want?" Melissa's smile disappeared as she looked at the masked face of the black mistress.

"Oh, is that any way to talk to a customer?" She smiled and leaned closer, prompting Melissa to take a step back. Today, she wore a cross between a latex miniskirt and a corset. Her otherwise bare breasts were covered by a pair of wide latex suspenders, barely covering her areolas. Her latex gloves and stockings went halfway past her elbows and knees. As always, she wore her spiked mask.

"A customer like you? Yes." Melissa put a hand on her skirt. She was wearing a one piece under her dress, but still didn't want her flipping her skirt up.

"Oh, be that way. Let's see. Today I will have..."

"Bon-Bon, is that you?"

The black mistress dropped her menu onto the wooden table and froze.

Lilly walked up to the table wearing red latex. "It is you. How have you been?"

Melissa was shocked to see that these two knew each other. She didn't know what to make of it. "Your name is Bon-Bon?"

The woman in black latex turned red. "My name is Bonnie."

"Yeah, but I just got used to her always calling you Bon-Bon." Lilly giggled and pulled up a seat.

"Well, I grew up, so you can stop calling me that now."

“Hmm, I wouldn’t count on that,” Lilly replied with another soft giggle.

"Um, do you two know each other?" Melissa looked over at Lilly. It was interesting to see the black mistress, or Bonnie as she called herself, be the one on edge for a change.

"Oh, her mother and I go way back. We had business deals and even went out drinking together all the time back in the day." Lilly giggled. "Why, the stories she would tell about her little Bon-Bon..."

"Bonnie! Even Mother hasn't called me that in years."

The latex dog poked their head out from under the table.

"Tell you what. How about I buy you dinner and we catch up on old times?" Lilly folded her hands.

"Actually I..."

Lilly didn't seem to be listening to what Bonnie said. "Melissa, get us the roast ham with the lemon glaze."

"And a half dozen pints of mead." Bonnie covered her face with her right hand.

Lilly turned back to face the woman. "Are you sure you want to be drinking so much so late? I remember when I had to enchant your bed so..."

Bonnie slammed her hands on the table, her face was bright red. "That stopped when I was seven! I mean, don’t talk about that kind of thing in public."

"I will have a pint of ale myself." Lilly just smiled. "Oh, and some ale for the dog."

"Right away." Melissa turned and headed back to the kitchen with the order. When she returned with the drinks, the two women were still sitting at the table. Bonnie hand her face in her palm while Lilly spoke with her about something. Whatever, it was, she stopped the moment she saw Melissa.

As soon as Melissa got close enough, Bonnie grabbed one of the pints and started drinking it. "About time," she grumbled.

"Oh, be nice." Lilly turned to Melissa and took her drink when she offered it. "By the way, I wanted to talk to you about something. Please clear your schedule 12 days from now." She playfully batted her eyes.

"Why?" Melissa looked at Lilly as she set the other pints down on the table.

"Oh, you know. Helping me with my little project. I will tell you more about it later."

Bonnie looked up from her drink, a little curious. "What do you mean?"

Lilly turned to face Bonnie quickly. "Oh, never you mind." Her smile remained, but the black mistress still looked away.

Clearly, it was about the omnisuit and she didn't want to talk about it in front of this woman. "I understand. I will see about getting the day off."

"Oh thank you." Lilly smiled warmly before taking a sip.

"You are welcome." Melissa smiled and walked away. For once, she got away from the black mistress without being grabbed at.

Day 66 of Omnisuit testing. Melissa arrived at a ranch just past the outskirts of town. She had gotten the details from Lilly when they were alone. She had to help stress-test one of the outfits at this ranch. Of course, she didn't bother to ask what kind of ranch it was.

She paid the cab driver before disembarking. As she walked through the main gate, she saw half naked women clad in latex running around a field. Some had their arms tied behind their backs, others to their sides.

"Just what am I testing out, anyways?" She walked closer to the fence, where a ponygirl with short brown hair walked up. She wore a black latex corset with red trim and a skirt that was too short to pass for a standard one. Attached to the butt was a large brown ponytail. Her high heel boots turned into black stockings and ran up to her thighs, while her arms were bound behind her back in black latex. She smiled around her bit gag as Melissa patted her on the head. She couldn't help look down at her exposed breasts, covered only by pasties and tassels.

Many of the other ponygirls weren't dressed so conservatively. Some pranced around wearing only PVC body harnesses, pony boots, and open-face latex hoods. Each of them had a bit and tail of some kind.

Melissa made her way into the building where a green-skinned catgirl was sitting behind the desk. She wore skintight latex with a diamond hole between her breasts. "Welcome. How can I help you?"

"Um, I'm Melissa. I’m here to see Lilly, err, Mistress Smith." Melissa blushed.

"Another? Very well. Please go to the hallway to your left and enter room number 3." She smiled and purred.

"Thank you." Melissa turned and walked down the hallway. "Another?" Her question was soon answered as she opened the door. Inside the room was a handful of women, each of them wearing latex catsuits. Some were basic, covering all but their heads, hands and feet, while others went further beyond, some even covering them from head to toe. Some of the outfits looked familiar to her.

A catgirl was playing with her tablet. She wore a pink and black catsuit, it even had a sleeve for her tail. Her outfit soon lit up, and the next moment, she was wearing a skimpy black latex bikini with black gloves and stockings.

"An omnisuit." Melissa blinked. She hadn't seen another 3rd gen in action before.

The 9½ ft tall amazon looked down at Melissa. "Don't you have one too?"

"Wait, are we all wearing omnisuits?" She felt like such a dolt for not realizing it sooner.

"That's right. Are you here for testing?"

"Yes, I just didn't realize there would be other people here as well." Melissa turned red. She wished she had put on a mask before coming here. A few of these girls already had.

The tall woman patted Melissa on the back. "Well, no need to be shy, we are all girls here."

An elf was the next to enter the room. Not long after, so did Lilly. "Hello, everyone. Thank you for joining us for today's test." She smiled as she clapped her hands together.

One of the other women stood up. "Given where you gathered us, I take it the test will involve ponygirls, and I get the feeling we won't be riders."

"That's right. I'm sure most, if not all of you, have the pony gear in your menu. I want to stress test the support enchantments that come with them. I have to be sure that even rookies can use them well enough."

"We’re going to be ponygirls?" Melissa blinked and covered her mouth.

Lilly smiled at Melissa. "Only for the day, my dear. To make things easier on you, I have split the males and females into different groups. Now, who wants to get started?"

After a moment the catgirl walked forward. "I guess I will go." She holds up her tablet. "Which one should I use?"

"Oh, I can handle that. My assistants and I will take your tablets to be ready to reverse the transformation, just in case." She took the tablet when the catgirl held it out. Soon, she pressed some of the icons.

Almost immediately, the catgirl’s outfit lit up, dissolving and wrapping around her tight body. It formed a black bodysuit that exposed her legs. Her arms were pulled to her bust as her hands were trapped in bondage mitts. A purple corset wrapped around her waist and pony boots formed on her legs. She mumbled behind her new bit gag just as it filled her mouth.

"Well, don't you make a pretty pony?" Lilly smiled at the woman. "Try walking around. Take your time."

The pony cat stepped forward slowly. Soon, she got the hang of it and was walking around the room.

"Very good. Now, let's all head outside. I have reserved a field for us today. You may leave your bags here but bring your tablets. I have tags you can put your names on." After giving them a moment to register what she said, she clapped her hands together. “That said, follow me.” Gesturing for them to follow behind her, Lilly walked through the back door and the other girls followed in a line. Soon, they exited into an open field. Closeby was a simple race track and in the distance was a wooden fence. A number of women walked up to them, many wearing gold collars. "These are my assistants who will help with the tests. Naturally, you will need to do all the things a pony regularly does."

"Everything?" One of the girls asked with a blush.

Lilly giggled. "While I don't mind if you get a bit more intimate while in your pony gear, whether or not you do will be up to you." Lilly stroked the chin of the blushing girl, pulling back a few seconds later. "Well, let's get started." She clapped her hands together. "And if any of you wish to volunteer for the more revealing pony uniforms, simply let us know when you hand over your tablets."

Some of the women were already holding their tablets. However, the others reached behind their backs to pull them out.

Melissa blinked as she looked at one of the women. "How did you do that?"

"Do what? Take out the tablet? Each of these suits comes with a built-in bag of holding. Didn't you read the manual?"

"I must have missed that part." Melissa blushed.

As the other girls started transforming, Lilly walked over to Melissa. "How is it going today?" She stroked her arm before taking the tablet.

"Um, fine. I didn't know there was a bag of holding with this thing. I have never used one before."

"Oh, I should have known. There are a lot of features we didn't go over, since they are all in the manual. To make things easier, each omnisuit comes with a bag of holding. It's a small one, just big enough for the tablet and some walking-around money." Lilly went over how to open it. Unlike normal bags of holding, there was no flap. Instead, it responded to the user's mind, opening and closing when she wished.

"Thank you." Melissa smiled after trying out her bag of holding a few times. It was then she noticed all the other girls had transformed and led away. She looked around a bit and saw them walking the track. "Um, should we catch up?"

"Yes, my dear, but first things first. Let's get you changed." Lilly swiped her finger across the tablet and pressed a red icon.

Melissa lit up, her clothes dissolving into ribbons of light that wrapped around her body, squeezing her tight. They formed a shiny golden latex catsuit and hood, exposing only her eyes and lips. There were two small holes for her nostrils and a golden mane attached to the back of her head. However, it didn't stop there. The legs ended in metal hooves that forced her onto the balls of her feet, a tight black under bust corset wrapped around her waist, and more straps wrapped around her body and even between her legs. Another ponytail appeared on her butt. Her arms were pulled behind her back and folded together, sealed in black latex. Finally, a bridle wrapped around her head and a metal bit formed in her mouth. Thanks to the tall collar that appeared prior, she could no longer turn her head, and thanks to the blinders, she could not see to either side.

"Mmmmm." Melissa tried to say something behind her bit, but couldn't. The small metal plate attached pressed down her tongue.

"Why, don't you look sexy like that? Here, let me show you." After taking a moment to stroke Melissa's side, Lilly walked in front of her and held her left arm. The largest gem on the bracer glowed and an image of light appeared above it. It showed Melissa in her golden pony form. The image moved as she did.

Melissa backed away for a moment, wiggling a bit as she struggled to keep her balance. This prompted Lilly to grab her harness to help hold her steady. After a moment, she moved forward to get a better look at the gold and black pony displayed in front of her. She watched as the breasts inflated to DD-cups.

"Now that you are all set, how about we get you started? Since this seems to be your first time, let's go slowly. I will be here to catch you if you fall." The image dissipated and Lilly clapped her hands together.

Melissa nodded the best she could and stepped forward. However, she soon found herself falling and landing face first into Lilly's boobs.

"My, aren't you a frisky one~." Lilly giggled as she held Melissa in place, patting her head. Soon, she helped her to her feet.

The mask hid it, but Melissa was blushing. She slowly started to trot to the track as Lilly held her reins. "I might as well make the best of this." She let out a soft moan as the latex rubbed against her skin, the strap between her legs digging in.

Once she was led onto the track, she started walking next to another latex pony. She was covered head to hoof in purple latex. If Melissa remembered right, she was an elf, not that you could tell with the latex horse mask she was now sporting. Not even an inch of her skin could be seen. Holding her reins was a dark-haired bunny girl dressed as a latex jockey.

Soon, the pair entered Melissa's blind spot as they walked alongside each other. In front of her was the tall Amazon. She was half-naked, with a good deal of her arms and legs showing her skin, her tight corset barely covering her massive boobs. She also had a saddle on her back but her handler wasn't using it at the moment.

Closeby, Melissa spotted another pony. She wore full red latex and walked on all fours. It seemed her arms were extended, perhaps with some kind of stilts. She too wore a latex mask in the shape of a horse’s head.

Melissa's eyes widened when she caught sight of the dark elf in the group. She wore only a body stocking and latex harness. She also had a snake tattoo wrapped around her left leg, something her skirt had hidden in the meeting room.

For the first hour, they just walked in circles around the track. They got used to their hooves and spaced each other apart in case someone fell. Melissa was surprised at how quickly she was adapting to this. The only thing was, she could feel how wet she was with the strap rubbing against her crotch with each step she took.

Once the first hour was up, they slowed to a stop. Lilly removed the bit and pulled a bottle of water from her bag of holding, placing it to Melissa's lips. "Drink up. You have earned it."

Melissa closed her eyes and enjoyed the feel of the cool liquid as it rushed down her throat. It felt good after the long walk.

"You have done well. I think you are ready for the sulky." Lilly stroked Melissa's mane.

Melissa pulled back from the empty bottle. "Sulky? You’re going to hook me to a sulky?"

"Yes, my dear." Lilly hooked bit back into place. "Don't worry, it's very lightweight. Normally, you would go through a few days of training on the wheel before pulling a sulky, but we only have just the day together. So I enchanted one to make it easier to pull." She stroked Melissa's arm. "Come with me."

Melissa had little choice as Lilly pulled her reins. She led her to one of several sulkies waiting. Some of them were already being hooked up to ponygirls. The Amazon, on the other hand, wasn't being attached. Instead, her jockey simply mounted her, sitting on her elevated saddle. The same went for the four-legged ponygirl.

Lilly slowly stroked Melissa's sides as she hooked the tethers to her harness. Slowly, she pulled back and sat down on the sulky's seat. "Forward." There was a jiggle at bit as she cracked the reins.

Melissa wasn't as strong as she used to be. Growing up on a farm had given her some decent muscles, but she hadn't done much in the way of heavy lifting lately. Still, as a waitress she was on her feet all day, and in heels no less, although not quite as tall as these boots. Slowly, she lifted her leg and stepped forward. Sure enough, the sulky didn't feel as heavy as she thought it would.

Slowly, she pulled the sorceress across the field. She made a small leap as she was struck on the rump. However, the boost didn't last long.

"Oh, I'm sure you can do better than that, my dear." Lilly giggled. "With ponygirls, trainers and divers often take a carrot and stick approach. Really, I am more a fan of the carrot myself."

Melissa let out a moan as something came to life between her legs. Her nipples hardened as more vibrations rippled through her breasts. "What are you doing?"

"Here is the deal: if you are able to go through the same routine as the others like this, I will let you cum. And it won't be just any climax, either; I can really rock your world."

Melissa made another jump as she felt a spike in the vibrations. Lodged in her nethers was a slowly growing vibrator. It teased her, but she couldn't get close to climax. She felt a little dizzy, but somehow found the strength to go on. No longer able to focus on where she was going, she simply walked and allowed the reins to tell her when to turn.

In her mindless haze, she heard various phrases like "Good pony" and "You can do it." This made her feel happy as her juices worked her way down her legs.

"Please, almost there... I need this... Must cum..." The reins pulled back, putting pressure on Melissa's tongue. She stopped, but soon dropped to her knees as the large member filling her womanhood to the brim suddenly went from light teasing to a full-blown assault. "Ahhhhhh!" She cried out behind her bit as she finally came. She then fell onto her knees.

"Very good, pony. You did very well. The tests have been an overall success." Lilly walked up to Melissa and started to lovingly stroke her. Slowly, she teased her nipples as another orgasm built up inside her. "I think you have earned your reward."

Melissa moaned through her gag. "Are we done?" She looked up as best as she could. She tried to stand, but fell back down, the vibrations rippling throughout her body. After a moment, she started thrusting her hips up and down. She wanted this, she needed this. She wasn't sure why she was so horny, even with the toy buzzing inside of her, and the hands stroking her didn't help matters either. Regardless, it felt so good, she didn’t dare question it now of all times.

Lilly toyed with her breasts, slowly teasing the nipples through the latex. One hand slid down her belly and massaged her crotch. Slowly, she pressed the vibrator deeper into her womanhood. As she got closer, she pulled her close and hugged her tight.

Melissa soon arched her back as another orgasm rocked her body. Going limp for a moment, she rested her body against Lilly's, who stroked her gently. Finally, the phallus inside of her died down. Her chest rose and fell as she breathed heavily, taking in as much air as she could around her bit.

"You’ve earned some rest. Come with me." Lilly tugged the collar. She walked Melissa to a fenced-off grassy field. There were a few of the other beta testers sitting inside of it already. "This is the rest zone. Just a place for ponies to relax in-between training sessions. Today, I set it aside for my testers." She opened the gate and led her inside.

"Finally. This is just what I need." With the gate closed behind her, Melissa walked only a short distance before she fell to her knees panting. "Couldn't you have removed the bit gag first?"

One of the ponies walked up to Melissa. She wore a single piece of purple latex over her whole body. It ended with metal hooves on her feet and hands. Her arms were free, even if her fingers were useless. Covering her face was an elegant purple horse mask. It had two blue lenses for eyes, limiting her vision to right in front of her. The pony sat down next to Melissa and gently nuzzled her. When Melissa leaned against her, she put an arm around her and held her close, gently stroking her.

"Mmmm, this feels nice." Melissa slowly closed her eyes as she recovered from the morning workout.

****


It had been a long day. Melissa leaned against the back seat of the pony cab Lilly had her take back to her place. Now she wore a long red latex dress with a black top. Her shoulders and upper back were bare, but she wore black latex sleeves to cover the majority of her arms.

It was a little strange watching the latex-clad ponygirls before her after spending a day in their hooves. It certainly was an interesting experience.

The scarlet-haired driver wore a black latex catsuit with a transparent cleavage window that went from her collar to her navel. She pulled back on the reins, the pair of ponies stopping at the signal. "Here we are, honey."

"Thank you." Melissa smiled as she got off the cart.

"No problem. Maybe I will see you next time." She smiled and winked at Melissa.

"Maybe. How much do I owe?" Melissa reached for her handbag.

"Oh, don't worry about it. The sorceress already paid me."

"Oh, okay. Goodbye, then."

"Have a nice night." The driver cracked the reins and the ponies resumed walking.

Melissa watched them go. She had a newfound respect for what those fillies must have gone through every day. After watching them leave, she turned and walked up the steps to her apartment building.

After cooking herself a nice dinner and enjoying said meal to the fullest, Melissa fell back onto her bed and let her arms fall to her sides. She stared up at the ceiling for a moment as she reflected on the day’s events.

Slowly, she sat up and reached behind her back. Opening her bag of holding, she pulled out the tablet. Setting the time to one hour, she pulled up her history and selected the pony garb she had worn only a few hours ago. Quickly, she set the tablet to the side.

Within a moment, a practical and literal flash, her suit lit up, wrapped around her, and reformed. She was once again a latex ponygirl. Pulling herself to her feet, she slowly walked over to the vanity mirror hanging on the wall across from her bed and admired herself in the reflective glass. Slowly, she turned herself around to check herself out, despite the posture collar and the limited field of vision. "Looking good." She smiled behind her bit.
