Hours earlier

Octavia had no option but to follow the stallion to the portal that was in the trunk of the tree, giving slow steps towards the hole.

From the other side, Octavia couldn't see much of what was around her. The room was in complete darkness except for a trail of parallel lights aligned with the path in front of her.

“Follow me please, and don't get lost," instructed Grigory #3 as he began to walk, not waiting for her reply.

Octavia stood there for a second when a hoof pressed her forward to move on.
“Please, don't keep the doctor waiting,” pleaded the mare.

Octavia did as told and began to follow the stallion between the lights of the hall.

The grey mare was a little nervous but not afraid, since she knew why she was here: it was part of their deal to report what she felt when she consumed the pills.

At the end of the hall, a door was opened for the three ponies, and from the other side, a laboratory was the first thing Octavia saw. It was far more elaborate than she anticipated, containing more than just simple flasks and and small machines. The lab contained giant computers, complex mechanisms, and strange artifacts that the musician had never seen in any city of Equestria.

Everything seemed so alien for her, so bright and noisy like a concert of her DJ friend but more monotone.

“Stay here," the white stallion broke Octavia’s examination with his words. The musician nodded as the stallion leaves.

Octavia was nervous and uncomfortable in this strange place, but a hoof in her shoulder surprised her.

“There is nothing to be afraid of. Cool Frost might look intimidating, but he is a good friend,” explained the shy mare with a smile. “Oh, and my name is Breach. It's a pleasure,” she added, extending her hoof.

“Octavia,” she replied, greeting the same way as the beige mare. “What is this place? I thought that he was going to come to visit me in the same place we met before?” she then asked in confusion.

“It is for safety measures. Now that the experiment has began, we need to keep it as discreet as possible, Miss Octavia,” replied Breach while she walked to a wall of the room and focused her eyes at it like she wanted to see through it.

“I... uhm... see,” Octavia stated, unsure if the answer was convincing or even calming for her current situation.

They both remained silent while the grey mare found it somehow strange that her host was still staring at the wall. She tried to examine the things this mare had, such as her simple body, her unkempt mane and the cutie mark of a black vortex with a purple star in the center, something that she would have expected more in a unicorn more than a earth pony like her.

“Ethereal energy ready. Beginning to open the portal,” murmured Breach while she closed her eyes.

Octavia leaned closer, trying to listen to what she said when all of a sudden, the wall began to blacken, and a dark spiral began to grow in it. Breach inserted her hoof inside the hole, and from it, she took out a platter with tea and biscuits. From her back, two tubes of dark, purple liquid began to rise out

“What did you do? I have never seen something like that before... or any of these machines, for that matter,” Octavia very curiously inquired.

“Quite curious, aren’t you, Miss Octavia?” a male voice eloquently asked as he entered the room. He had a mahogany red mane with a light brown coat. His eyes were in a golden tone, and he was wearing a tattered lab coat that seemed burned and damaged from a long time ago. “I would gladly give you an explanation, but I’m afraid that I would need fifty years of our lives to do so,” he replied with a hint of arrogance, smiling at the mare.

Octavia glared at the stallion, feeling the clear insult at her intelligence.

“Hello, Mister Raziel,” Octavia said with no enthusiasm at his presence. “I believe that Pon-3 would be delighted to be in such a place. The noise and electronic devices as she calls them are really… something to see for her,” she then complemented with a bored expression.

Raziel chuckled at her words and sat in front of the mare at a distance with a smile, while a pegasus mare delivered them a set of tea with a kettle and biscuits.

“Here is your tea,” the beige pegasus mare kindly stated as she placed the set between them both and served them each a cup.

“Thank you, Breach, and prepare the machine in three minutes,” said the stallion, before taking a sip of his tea. Breach nodded and left, trotting to the door.

“What is she?” asked Octavia, noticing that the pegasus wasn’t a pony of flesh and blood.

“She is one of the CP, of course,” replied Raziel with a smile and pride. “She is an android, made by an excellent metal from Theron and infused with magic that grants her the power of creating portals,” he explained.

“Did she consent for such a thing?” asked Octavia, looking a little concerned for the other mare that just left them.

“Octavia, I do believe that you are here for other reasons,” interrupted Raziel as he then served the beverage to the musician. “I do have to say that your transformation was surprising in some ways. I was expecting something more simple,” he added with a satisfactory smile.

Octavia’s eyes widened as she almost dropped the cup from her hooves.

“You saw us!?” she exclaimed, surprised.

“Of course. I need to have everything documented and analyzed,” he pointed to a monitor that showed the carnal display of both the pony and human. “And with that, my first question is made. How did you managed to move that new body with such ease?” he now asked, leaning closer to hear her answer.

Octavia was embarrassed that their private moment was seen by others, but watching the video made her smile that she had such an excellent time with Jason.

“It was almost natural, as if I was born with it. I then felt the thoughts of him using his body, and by reflex, I got a hold of it,” she explained, trying to recall everything they both did.

“So, it seems that he didn’t just imagine your new body, but also transferred his thoughts of common knowledge in the use of it,” theorized Raziel, while taking a bite of the biscuit. “Now, please tell me everything that you felt from your time with him, and please do not omit anything… After all, this is for science!” he then ordered with a smile.

“Okay,” said Octavia as she took a long gulp of her tea, to gain a sliver of courage, and began to explain everything that happened, from how she felt and what she thought she did. She explained the part where she was compelled to act as nurse to treat him, and the need of clenching her need of lust through his body.

“Interesting. Thanks to that, I have the data I need about these pills. Thanks for offering yourself, Miss Octavia, for being the first volunteer of the pills,” said Raziel while finishing up his tea and standing up.

“I just did it for Jason, and if there is no need for me and him, I wan-” Octavia wanted to finish this and return to Jason and tell her feeling for him, but Raziel cut off her words as he spoke once again.

“Although, I still need more research on the matter, and for that, Jason needs to continue with this experiment,” the doctor stated with finality.

Octavia was dumbfounded, and she tried to think in what to say.

“What!? Why would you need to continue this!? You have your information, the visuals and my explanation... What else do you need!?” exclaimed Octavia with anger as she stomped her fore hooves on the floor.

“Variables. I still need to see the effects of the pills on other ponies along with other possible creatures. Maybe with princess Twilight too, glad to know there is an alicorn nearby,” he answered, giving his back to the mare. “Along with seeing why it is the pills wore off in the first place, we also need to examine the possibility of going further with the transformation,” he added.

“But... you said that he was going to use them on me, and with that, you would help me be with him. I want to be the one to have the body he wishes others to have!” Octavia exclaimed, but then realized what Raziel just said. “If you force him to continue with this, he would be in serious trouble!” she added with concern and worry for her beloved one.

“I am really sorry, taking advantage of your weakness for my personal gains, but that is how I do things,” Raziel hadn't looked at her in the slightest as he then lifted a black metallic orb with neon green lines. “Activate it,” he then told to the sphere.

Octavia was about to shout at the stallion, but a sudden tingle around her body began to make her feel dizzy and very sleepy.

“I am not sorry for doing this to you, Octavia, because you would go after him and interfere with the experiment,” said the doctor while he nodded at an upper window, from where Breach was pointing a laser machine, sending blue rings at the mare. “For that, you will be implanted with a suggestion of thinking that what happened was just a simple activity between the both of you, and your feelings for him will be at a minimum, as in more like simple friends and memory implant for your absence in the town,” he added, while he trotted away.

Octavia stood there, with a thousand yard stare for a moment, and then, Breach stood near her to teleport the grey mare to another place.

She blinked twice, looking at the hill where she sat. She didn’t see anything out of ordinary when a high pitched voice made her recall why she was there.

“Why did the mother snake punished his son? Because the little one stuck out his tongue, Giya ja ja ja,” said Cherry Bomb next to her, laughing at her own joke, as usual.

“That one wasn’t as funny as the other, Cherry. You better exchange it for another,” recommended Octavia, remembering that she was helping her friend for her comedy routine.

“Very well then, how about this one?” Cherry then began to tell her next joke, when from the distance, Jason walked towards them.

***

Jason stood there with the note in his hands as he tried to look for anypony around, but he didn’t see any living creature nearby.

Jason then decided to read the note.

Foresight Industries thank you for your participation with the recent data of the effects of the pills. We managed to obtain much useful information about them.

We also like to invite you for the continuation of the use of the pills on others around the land for continued research. More extreme results like the recent test, the better. The current pills have already been exchanged for a more potent batch back at your estate.

Foresight Industries would likely to keep these activities as low profile, and requests its clients to not divulge anything, for it would be bad for other enterprises to obtain such product from you by force.

So, for your security, please refrain to say a word, even to those you believe you trust.

Foresight Industries and Dr. Raziel thanks you for your cooperation.

That was all the letter said, leaving the human quite perplexed as he read it again.

He didn’t understand what the letter meant, since he never told anypony, yet, about what he did last night.

Jason now remained on the hill, thinking of the options. It still bothered him to be a lab rat for an unknown company, but the sex he had was something that he enjoyed more than he could ever have imagined imagined. Thinking that he could obtain much more made it an easy to take the decision.

Running with full speed, Jason didn’t hesitate to go to his house, where the improved pills would be waiting for him.

Passing by the streets of the town and its residents Jason rushed to his home.

He opened the door of his house, and inside was the package he was supposed to find, on the counter of the kitchen. Jason was a bit uneasy that the box was inside his home. Seems his privacy could be easily invaded by whomever is doing this.

With hesitation, he took the small box and opened it. Inside was the same two jar of pills, along with another note. The only difference this time iwas that the jar that contained the green pills now had sky blue ones that seemed more medicinal this time.

Jason then took the note and began to read it.

These new pills grant the next improvements:
Alteration of body size.
Alteration of age
Alteration of color of the coat.
Alteration of thoughts.
possibility of estrus.
possibility Lactation.
Any other change will be/are possible, please handle with care

Jason forgot his paranoid attitude and gained a wide grin in his face.

He could only think of the endless possibilities of how to imagine the bodies of every single mare of the town in different shapes and forms, the size of their tits or hips, even the muscle size of their legs.

Jason could feel his mouth water at the possibility to engage one of the many fetishes he always had dreamed and the roleplay. Oh, sweet acts during the sexual relationship.

Jason felt that he had a big opportunity in his hands as he pondered on the next mare he would be getting laid.

Octavia passed through his mind. That moment where they both collided their heated bodies with passion. Jason could recall that Octavia enjoyed the moment more than he thought she would. Instead of him having took advantage of her, it seemed more like she wanted to do so, but it was the thoughts of what happened on the hill that made him reconsider choosing her right off the bat.

“Well, there plenty of mares in his town, so let’s choose with no pressure,” he told himself as he then left the house, having decided to walk to the park.

Jason walked through the gravelled road and took a seat on the bench to watch the ponies pass by from left to right. Usually, he just sat there to observe them and how shamelessly they displayed their naughty bits, as they called them, to accommodate the idea of what he has left of his perverse mind, but that still made him really uneasy by the fact that they still resembled animals in the most of their forms.

Now, he could change that. He could make them into whatever he wished them to become, but there was still one single detail that interfered in his goal...

...how to convince the one he chose to join him with this experiment. Octavia was easy, but that was because she just consumed the pill in one go. The rest was simple.

There was one mare in town who could find the idea attractive, and she was just walking down the park near him.

Lyra was trotting happily with a happy tune being hummed, passing by some ponies and greeting them one by one. She soon passed next to Jason.

“Hello, Jason,” greeted the mint coated mare as she still continued in her pace.

Jason wanted to ask the mare about the opportunity to become what she had always wanted to be, but he was beaten to talk to her.

“Lyra! Glad you made it!” Bon Bon shouted as she hugged the mare who arrived.
“You know, I would make time to be with you, Bons,” replied Lyra as they both left the park with a giggle, walking alongside each other.

Jason felt that his opportunity got busted, since Bon Bon would be an interfering factor to the secrecy of what he promised to the ones he received the pills from.

“You seem a bit gloomy there, pal,” a female voice called, waking Jason from his thoughts.
“Hello, Berryshine. I just lost a partner in crime for a little something I planned,” replied Jason, looking at the plum coated mare.

Berry smiled at the idea of a plan in the mind of the human, as he seemed more interesting than it could be.

“Well, since I have no plans for today, I would like to be that partner in crime,” she offered with a smile as she sat next to him.

Jason smiled at the offering of the mare and leaned his back on the bench as he felt more relaxed.

“Well, you can come with me to my house for something I planned,” Jason said as he rose from the bench and waited for the mare to follow him.

“I do hope there will be something fun involved in this plan you have,” Berryshine followed the human to his house with a smile and the thought of something interesting in mind.

“Don’t worry. It will be as if it was the opportunity of a lifetime,” said Jason as he remained looking forward.

“And there he goes, ge hi hi hi,” Cherry Bomb chortled as she followed the two from a safe distance, but soon took an alternate route to Jason’s house.

Jason and Berry continued to their destination, when the plum mare couldn’t contain her curiosity.

“So, what are we going to do?” asked Berry, keeping her pace with the human.

“We will go and have a drink of a special mix I have wanted to make for a long time,” replied Jason, preparing in his mind a plan to make the mare take a pill.

“Oh, Jason, I know that I am well known for being a critic for juice mixes, but I didn’t think that you just wanted me to come with you just for something as simple as that. Is that what this is about?” asked Berryshine with a smug face, as if she could see the deception of Jason’s words.

“It’s a surprise, so please be patient,” pleaded the human with a smile of his own.

“Oh, how do you know that I like surprises?!” said Berry with a giddy grin as she stifled a giggle of emotion.

They both continued on until they arrived to Jason’s house and entered.
“Get yourself comfortable. I will make the drinks first and bring them in,” Jason walked to the kitchen to take out a big jar of a mixed juice he just bought from two days prior and served them in two glasses, he then quickly took out the two jars of pills and placed a different one in each glass. He doubted if the pill would go unnoticed, but he still continued with his little plan.

Jason returned to the living room, where Berry was looking around the place with a mild curiosity, constantly reminding himself in which glass had which pill he needed to consume.
“Here it is. I hope you like it,” he said offering the glass where the blue pill contained.

Berryshine looked at the glass of juice and smiled.

“So... did you make the special juice from the store? Interesting,” joked Berry with a smile as she drank all the continents of the glass.

“Heh, sorry for saying that it was of my making,” replied Jason as he drank his own juice as well. ”I thought it would be a good reason to bring you here,” he added as he scratched the back of his head nervously.

“Oh, Jason, you just had to ask, and that would be enough for me to be here,” assured Berry with a grin, leaving the empty glass in the small table. “So, what is the real reason you invited me here?” she then asked.

Jason smiled as he began to formulate his thoughts. “You’ll see in a minute,” he only said.

Jason had thought on what he wanted from the mare, aside from the nearest human form possible a pony could be, but he now needed to think of changing her coat and mane color and body size.

He had to think fast, imagining the many things Berryshine could become, and with that, he now imagined a woman with blue mane yellow butter coat and blue sapphire eyes whom was very tall and with a very unique voice. This time, he also imagined her in a white dress encrusted with some gems, along with golden details, along with a small hat in the same asthetic.

Berryshine’s expression changed from excitement to confusion, but as they both stood there in complete silence, her attempt to break the silence got interrupted as a tingle of light caught her attention. She then noticed that she was the one who was glowing.

“What is this?” she asked in between fright and curiosity, feeling how her body tingled in magic and slowly began to levitate as the white light enveloped her entire body in a cocoon, like the last time, and soon dispersed, showing the almost human mare that Jason had thought.

The now transformed Berryshine looked at herself curiously, looking at her new appendages that once were her fore hooves. Then, she observed her breasts that had a decent size of D cups before then observing her new legs, which still resembled what they used to be but were straighter and with a different color.

Jason was a bit confused that the mare in front of him didn’t have any clothes on her, since he thought that it could be included as part of the spell.

“Guess everything has its limits, since they still look like ponies but only on two legs,” he muttered to himself as he still enjoyed the sight of the mare in front of him. “Berryshine?” he called to gain her attention, but she didn’t respond.

“Berryshine?” Still no response. Jason was a bit worried now, as he then tried another tactic. “Sapphire Shores?” The mare in front of him looked at Jason with a smile.
“You called, honey?” she asked with the sweet tone the singer had.

Jason was truly surprised that the pill took all the length to alter the memories of the once known Berryshine to make her believe herself to be the pop-star singer that everypony knew and loved.

“Are you alright?” Jason mentally slap himself in the forehead for making such a dumb question, but that was the first thing everyone thinks when something changes drastically.

“Honey, let me tell you that I feelseeeeeeeeensational!” replied the new Sapphire Shores with her usual accent of shouting her favorite word, pulling her arms in the air while displaying her new body for Jason.

The human felt his heart rate increase as he admired the naked body of the mare in front of him, and all that blood rushed to between his thighs, making him full mast.

Sapphire noticed this and smiled, “Honey is that a microphone, or are you just happy to see me?” she asked, mockingly while taking a few steps to be in front of him.

Jason could only remain erect as the mare gave him a sultry look with her eyes, and with her left hand, she slowly went to touch his personal care package.

“OH! Wait, wait!” Jason stopped her advancements with his hand and looked at the mare. “Can we continue this in my room?” he offered with a smile as he placed a hand on her cheek.

“That would be excellent, Dear,” replied Sapphire as she followed Jason to his bedroom.

At the house, Jason sat down in the bed while Sapphire stood in front of him, making a sensual pose for him to admire.

“Now relax, Honey, for I am giving you a private concert.” She slowly walked and gently shoved Jason to lay back on the bed, and she began to find it quite strange and really amusing on how easy it was to use her new appendages to undress the human, since for something as small like a zipper she would normally end up using her mouth to undress him.

Jason remained still while Sapphire did all the work. He only assisted in pulling down his own pants.

Sapphire smiled as she took a good look of her prize.

“My, I never saw something like this before,” she complimented as she then gave it a few strokes with her furred hand.

At this action, Jason could barely contain his ecstasy to not cum at the simple touches of the mare, but the ooze of precum could flow slowly from his erect member.
“A free sample, eh?” Sapphire used two fingers to take the small droplets and savored them in her mouth. “This taste seeEeeeEeensational!” she then exclaimed at the flavor of the human’s fluids.

Jason smiled at the reaction of the now known singer as he then noticed the now soaked honey pot from her.

“You seem to enjoy this, so why don’t you perform a private concert for me?” he asked, pointing out that she could begin with the initial insertion.

“Oh... you will love how sweet my vocal cords will sing for you!” she replied as she then began to position herself in alignment of Jason’s virile member.

“Mmm oooh,” moaned Sapphire sweetly, as the initial thrust pierced through her flower as she placed her hands at her thighs. “This is truly different from any stallion that I had encountered before,” she said with wide grin on her face of having a new experience.

Jason smiled at the supposedly well meant compliment, enjoying the sexual intercourse of the mare on top of him.

Sapphire now began to go slowly and steadily in her movements with her hips, pumping his penis with glee as she started to go faster and faster.

Jason decided to participate in the action he placed his hands on the mares hips and slowly began to caress her body, tracing a line upwards to her ribs and then to her erect tits, giving them a firm squeeze and making Sapphire moan in approval.

“Oh, yes, honey. That is the spot! Right there!” she moaned and took a quicker pace with her hips.

Jason couldn’t last any more as he reached the top of his limit, but the tension in Sapphire’s pussy signaled him that she was about to climax as well.

“Let me hear that sweet tone of yours, Sapphire,” he commanded as he finally let himself go in a total burst of white cream that clashed with the yellow mare’s fur.
“Oooooooooh, YES!” cried the singer placing her hands on her head as if this one scream would blow up the sky.

The two began to take some breaths as their ecstasy began to die down a little as in Sapphire’s eyes widened in surprise when noticing that Jason seemed up for another round.

“My, you seem to be able to go for more than one shot, and that is seeeeeensational!” exclaimed Sapphire as she began to pump his member to get it full mast one more time.

“Now, if you enjoyed the performance... then you will love the encore,” suggested the mare as she placed herself on all four, showing her rear to him and waving her tail to make the human take a good look of her honeypot.

Jason couldn’t resist such an invitation as he crawled to be in position to take the mare Doggy style.

Grigory #4 observed everything and placed a silence spell to avoid any filtration of sound that were caused by the singer’s screams of bliss, just in case anypony happened to pass by.
