Prologue

A morning, like any other, the house of a scientist is strangely calmed; nothing happening else than the birds singing on the window and sunlight bathing a little bed, with a dog sleeping on top of it, Spike is sleeping really deep with his paws moving like he was digging a hole in the dirt, doing little cute roars with each move of them. Suddenly, a door slamming open awakened him, Twilight got out of her lab with that smirk that would catalog her as a mad scientist.

"I made it, the perfect dog cookie that would make your capacities be better!" She yelled to the air, while Spike blinked trying to not be annoyed by how lowd her voice was for him.

"Could't you just... buy it from the store? For once..." Spike complained, he was not awake enough to care or to try another one of Twilight's weird experiments.

She looked at Spike while still holding the dog cookie. "Nonsense, i don't like what they put on those. Come on try it out, this one would not have any side effects" Twilight assured to him, but he only raised an eyebrow with a very serious look in his face. "What could go wrong? I bet it tastes good"

"What could go wrong? Like when you made that robot for me to calm my rut and electrocuted me? Or that time you made a shampoo that made my hair grow without control?" Twilight's face changed to a worried face, not all experiments go as planned. "Did you even tested it before me? I don't want to end with all my hair off my body"

"Well ok, i got your point... geez, don't be so harsh wit~" Twilight got a message on her phone and read it; leaving the cookie aside of Spike's bed, then she got disgusted making a 'bleh' sound that filled the whole room. "Dang it, Sunset... why you had to send me this? Wait are those Applejack and Fluttershy too?" In the pic Sunset could be seen alongside Applejack and Fluttershy at a stable on Sweet Apple acres, the three girls licking a stallion's shaft with their tongues and mouths. "I don't get it, what's arousing about that? It doesn't seem like they should be turned on by something like that"

"Not everyone is the same" He then gave a quick smell on the cooking and gave it a quick bite by curiosity. "You can't expect to understand what makes them like it"

"Or maybe i can" She giggled.

"Wait what?"

She adjusted her glasses on her face and raised her head up to the ceiling. "I'm going to experiment with kinks and how the human psyche relates them to pleasure; i'm going to find the explanation no matter how hard or disgusting it may be, for science!"

Spike wasn't surprised, he knew Twilight tended to take things to the limit; then he felt the effect of the cookie he bited and sighed. "As long as i'm not part of it, you do you... now, if you excuse me, i'm going to hump a pillow for the next few hours" Spike left the room, Twilight saw that he had his dog shaft really stiff; but that was not her worry now.

Let the experiments begin...

Chapter 1: Basic Insertions

View Online

Twilight was excited to test the many kinks and things people do for giving theirselves some pleasure; so for that she prepared her whole lab for those kind of experiments. For all of them she prepared a shower, webcams, clothes and she even has some toys that her friend Rarity forgot at her house at one of the many sleepovers they had; she really knew Rarity brought them because underneath that sweet and classy cover she has... deeply likes to act dirty, Twilight had it keep those toys with her; she was really planning on giving them back to Rarity but never got that chance and now that she has an excuse to use them... why would her give them back?

Twilight turned on the webcam and started recording. "Well, ok... logbook on lewd human psyche, entry number one" She said loud and clear while looking at the lens. "This is the first day on trying to understand how kinks and lewd stuff affect on the human psyche. As i'm not used to this kind of things, i decided that for the first day i'll do something a little soft as start with... this" Twilight showed the toy she was going to use, a pink looking dildo, about five and a half inches, shiny and with a button on the base. "Not much, but it may be a good start. I'm proceeding to start the first experiment"

She placed the dildo on top of the table and then pulled down her panties all the way to her ankles and sat on a chair putting her feet on top of the table, exposing her slit to the webcam while grabbing the dildo. She gave a deep breath before looking at the toy and then at her crotch, she pushed the tip between te lips and rubbed it against it up and down slowly; a quick tingle went all the way up and down her body. Twilight was someone that really didn't cared much about how her crotch looked, so she had a very hairy slit, the sounds of the toy rubbing was a mix of wet elments and hair scratching.

She blushed, as she wasn't expecting how that thing would feel. "It has a very cold feeling, but seems like it quickly changes temperature to adapt itself to the user's crtoch natural heat" She spoke again to document in the log, she kept grinding the tip of that toy between her lips until it clings at the entrance of her pussy; she gulped after feeling it. "Now... i think i should push it inside"

Taking her time, she didn't knew if it would hurt, she took a few seconds to rethink on it but then pushed it inside her pussy; causing her eyes to get wide in surprise and her legs to twitch like crazy, causing her shoes to slip off her feet; until they stopped and she places at least one of them on the table, hard to keep it on top of it cause of her socks. She pulled it a little bit out, she then saw a little bit of blood on the toy; as she never had any sort of sexual intercourse because she was not interested on them, she had her hymen intact, even tho she knew some women don't even have that thin wall.

"My... that was an interesting feeling" She then pushed it again inside her pussy, moving it in and out as quick as she could; that was it, the first time Twilight has ever masturbated with a propper toy. Twilight tried masturbation some time back, but at that time she thought it was a not worth her time, so she just did once and never again until now. "The feeling is as i previosly said, interesting; the falic element tries to adjust the insides of the female's vaginal walls to it's shape... i kinda can feel it shaping itself and being tight to it" For the first time ever, Twilight enjoyed something related to sex; as a surprise for her.

She then pulled it out, the toy was covered in a really thin layer of her pussy juices. With that now lubed, she needed to recopilate a little bit more data and she knew how. She changed her position, and aimed her butthole towards where the webcam lens was, then pushed the toy inside her butt; it didn't go in immediately, it struggled a little because her butt was really tight... but with a little more strength she managed to push it all the way inside and moved it in and out with carefull of not hurting herself. But for her bad luck she pressed the button that was on the base, turning on the device and soon, the toy started vibrating inside of her butt.

"W-wha~" She couldn't say a word, the vibrator was something that she was not expecting at all; she thought that it wouldn't not have any batteries because of the many uses that Rarity may have done to it. "Rarity... you should have used it more... why does it still have batteries charged?" She couldn't stop and she didn't wanted it to stop, the move of her hand and the vibration inhibited most of her senses and thoughts. She kept pushing that toy deep inside her buttholeuntil she squirted for the first time, a very fluent and powerful shot of her juices felt to the floor underneath her making a huge puddle that luckily didn't wet any electrical elements.

Twilight turned off the vibration from the toy and unheld it, it popped itself out of Twilight's butthole falling hard to the ground. She was panting really hard, recovering her breath from that intense feeling, every single hair on her slit was wet from all the juices that sprayed out. After recovering a bit her senses, she pulled up her panties and looked into the webcam, with her face as red as a tomato and looking a little ashamed that she did that; she cleared her throat before saying anything again.

"Experiment one conclusions... the feeling of falic or stiff elements can stimulate the walls of both the vagina and the anus in ways that a finger couldn't ever hit" She spoke calmed but it was obvious that she enjoyed that a lot. "The element is able to inhibit the neuronal functions of some thoughts making the focus on that intense feeling. In any case, i still need to experiment and research a lot more; soon we'll do experiment number two. Twilight's log... off" She said as a finish to the log before turning off the webcam and leaving the lab behind.

Esperiment Number 1: Toy Insertions

Chapter 2: Legendary Lingerie

View Online

Sounds of steps are heard, someone walking closer making some noises of lifting something until a big relief breath is heard, the monitor screen is then turned on, Twilight is just placing a box perfectly aligned to the view of the table of the webcam, but then Twilight saw the monitor and saw the red light of the webcam on; noticing that it was recording.

"Oh, please don't tell me that i left this recording during the night?" She checked the log and noticed that it had about more than sixteen hours recorded; her eyes widen, but that's something she can fix in just a few minutes, she stops it from recording and searchs from where she said that it was the end of the log. After doing that, she looked at some of the things she made while using that toy; she couldn't believe that she made such things like toying herself and squirt like a broken water tap. "No worries Twilight, this is all for the sake of science. All you felt was something a newbie was not ready to experiment, but now your brain cells are ready for whatever comes"

She then stripped out all over clothes; she wouldn't need her everyday wearing for today's experiment; as soon as she took off the last piece of clothing, she felt a cool breeze shivering her body like a drop of water driping exactly where the neck is. Twilight prepared the webcam to start recording, she made first a quick audio test to check that everything is ready for the second log of her experiments.

She started recording and looked straight to the lens with a smile on her face. "Logbook on lewd human psyche, entry number two" Again, she spoke loud and clear to the recording device; she grabbed the box and placed it where the webcam could get a better view of what is inside. "For today's log i thought that after having that first intense experience i thought that it would be better to have something a little less intense. So i bought something and i'm going to try out... lingerie!" She opened the box and the webcam recorded what it looked like to be a set of white lingerie, Twilight had problems to move the box because she picked a very heavy cardboard box to store those clothes.

Twilight grabbed piece by piece showing what that set of lingerie had: A brasier that was partially see through with flower patterns, two lace stockings completely opque with reinforced toes, a very small thong, that would qualify more as a g-string because of how it barely would cover something and finally a pair of elbow gloves that were almost as transparent as the brasier. In front of the cam, she started to put on slowly every piece of that lingerie while she was sitting on the chair; starting with the gloves they felt smooth going up her arms, fitting her fingers and her arms perfectly, then the bra followed up; it was a little tight to her chest but felt like some hands were grabbing both her boobs gently... she was already blushed and she only was wearing two of the total pieces of that set of lingerie.

Then she took the g-string and slowly pulled it up her legs until it reached her crotch; it was so small that barely any of her pubes were covered by it, the top part and the slit zone were sticking out showing completely; she couldn't understand the purpose of a piece of clothing that barely could keep public hair inside the fabric. Finally she picked up both stockings and slowly pulled them up her legs, all the way up to her thighs; the sensation of them pressing against them was, again, like a pair of hands grabbing really tightly. Once both stockings were on her legs, she stand up of the chair but for her surprise she didn't used her whole feet; she was just using her toes and holding herlsef to the table very carefully with her fingertips.

"This is curious, the touch of this soft fabric kinda tells my body to be carefull" Twilight then walked around the lab; as she was walking in little tip toes she noticed that her hips wiggled like one of those models of the magazines in high heels; always showing off their huge body proportions, Twilight didn't had wide hips; in fact she had things that some would consider sexy such as her bushy pubic hair; but at that moment she really was feeling sexy. "So, this is what supermodels feel like? They like this much to show their bodies?" Twilight couldn't focus correctly on the subject, that was understanding how those clothes worked as a kink. She then saw the corner of the table and walked closer to it. "Maybe... i should do..."

Twilight pushed her crotch agains the corner before lifting a bit her right leg for a better positioning, she felt how the corner of the table hit her clit through the fabric; Twilight needed more so then she started to grind her slit faster against the corner. As some sort of wild instinct, Twilight raised her hand and grabbed her left boob and squeezed it as hard as she could but also pinching her nipple; as soon as she did that her mouth did the unthinkable... moan.

Twilight covered her mouth, her cheeks turned very red as she really didn't expected that at all. "Did i just... moaned? That was legitimately a moan..." Twilight understood, the lingerie being a very soft clothing incentives the body to be touched by the wearer of the companion; unlike with the toy that just focused on being inserted and stimulate the body from the inside, lingerie is focused on the skin and how the hands are invited to move on every inch of the fabric covering the sensitive parts of the body; the legs the crotch and the nipples really feel their sensitivity increased when that fabric is covering it. "Maybe a little more won't hurt me! After all, it's for science..."

She sat on the chair and placed herself in front of the webcam, she smiled before starting to masturbate in front of it. Her gloves were making the feeling even more sensitive, she rubbed her slit with one hand while the other played with her nipple; constantly pinching it and this time not holding back any moans, if she had to do them then they would fill the room completely. Twilight used two fingers to rub her clit through the g-string, juices were making that very thin fabric really wet and staining also the chair she was on top; the blueish soft cover that the chair had were turning darker thanks to all her natual juices going leaking, as well as her pubic hair; all wet, all pleasure, louder moans escaping her mouth for as much long as she was playing with her body.

"I'm feeling tingly... i'm about to..." Twilight then closed her eyes and then squirted, but with a little less intensity than previously; as for this time she was doing it at her own rhythm instead of a random object vibrating all of sudden. She sat propperly on the chair and looked again at the lense, her face really showed how much pleasure she had from that; it was just clothing but it felt incredibly good. "Just as i expected, the extremely soft fabric used in these type of clothing makes the touch more intense; and sensitive zones such as the nipples and clitoris way more susceptible to such playful kind of touches, orgasm seems like a more natural reach like this; or at least the teasing prepares the body for the action that comes next, which in normal situations i guess it would be sex" She then started to take off the lingerie piece by piece, first the bra, then the gloves, when she was pulling down the g-string she saw the piece of clothing connected to her slit with a trail of her juices, that view made her blush again and gulp a little of saliva. "Aditionally, these clothings have an effect of making the body look sexier; but this maybe is different depending on subject. Experiment two may qualify as a success"

Twilight turned off the webcam and stop the recording; she put her everyday clothes and went out of the lab. Spike looked over her and noticed the smells of her body. "So, your experiments are going great?" He asked, but deeply he didn't wanted to know the answer.

"They're helping me understand; i just made two experiments. That's not conclusive at all" Twilight then sat on the couch, hiding her obvious arousal that Spike was able to smell.

"And all because of a picture of your friends. Wouldn't it be easier to ask them for an opinion, rather than doing all by yourself?" Spike tried to make a point. "Experimenting all by yourself seems... how do i say this? A little selfish..."

Twilight snorted. "Selfish? Not at all, in any case it would be scientifically accurate as some get better results by doing them alone" She then picked up her phone and started searching things on it. "If you excuse me, i have to prepare tomorrow's experiment" She stand up and went straight to her room, causing Spike to sigh and roll his eyes, he just doesn't want to be involved into what she's doing. She has to learn by herlself.

Chapter 3: Golden Elixir

View Online

Twilight's first two experiments were surprisingly good and arousing, considering that she never did things like that; it was a nice surprise that her body had a positive response to those kind of things, but it was truth that she did very basic things like masturbating with a toy and wearing lingerie... but soon she would have to dig in other kinds of kinks, the best place to look for those? Obviously that huge network of so easy to find porn called internet.

Twilight was at her room, with the computer on and she was trying to find some not so common kinks; or at least some that she didn't knew about, but most of the things she found they were common: foot fetish, breastplay, anal... things that she knew some would be turned on with, no big surprise there; until she found a strangely named one, one that she never heard about.

"Watersports? Are you telling me i'm going to need a pool now?" She joked then made a singe but loud belly laugh, before clicking on the link thinking that she would only find girls in pools and swimsuits; but as soon as the page loaded... her eyes widen in complete shock. "W-wait... what in the...?" Twilight tried to process with her eyes what she found, videos and pictures of people playing with urine in plenty ways like wetting their clothes, spraying it on the partner's body and drinking it from glasses or straight from the source. Twilight shut off the computer's screen and looked in front of her, like staring into a void; she then took a deep breath and looked at a mirror determinated. "It's for science... and i must test it!"

The lab's lights were turned on, Twilight prepared a remote control to start up the webcam for recording without needing to walk closer to it. She prepared the shower she had in the lab, Twilight knew she would need one; she had it already for when some of her earlier experiments were a little... explosive cause of an unwanted mix; on a smaller chair aside of the shower she placed clean clothes to change the one's she's going to use. With everything on place, all Twilight had left to do was start the next log.

Twilight hold the remote and started to record her; the webcam was placed in a zone where it could record her perfectly. "Logbook on lewd human psyche, entry number three. Today's log is going to be a little... smelly as the subject of today have a special work on cleaning causing it's strong smell" as soon as she finished the sentence, she took off her shoes and leaved them aside of the shower, then went to a shelf to grab a recipent just to place it in the floor of the shower while she was walking inside as well. "But enough anathomy, i'm going to fill this recipent here with my own urine... commonly named pee; i'll do it through my panties using them like a filter"

She squatted, with her thighs barely resting on top of her heels; legs spreaded whide open, with her skirt lifted slightly showing a pair of white and blue striped panties. Twilight layed a hand in a wall, meanwhile the other hand rubbed on top of the cotton fabric of the panties, looking for the clit. Once she spotted it with her fingertips, Twilight rubbed it slowly to stimulate it; causing her to let out a very soft moan, she kept doing it until it started to feel tingly and a darker tone were forming in the fabric. Soon Twilight was pissing through her panties, filling the recipent underneath her, the panties were getting a little golden tone while some of that warm liquid moved along her thighs, staining her socks too.

She finished and looked at the recipent, it was half filled. "Part one of the experiment done; next one i'm... not so sure about it" Twilight gulped a bit of saliva and looked at the gold looking liquid, the smell was not good at all; but she was tempted to give it a drink; holding the recipent with both hands and lead it closer to her mouth, she was blushing deeply, as soon as it touched her lips she gave it a big sip and swallowing it. Twilight made a face showing her disgust, but that warm feeling down her throat was strange. "It's saltier than expected and... geez, it tastes horrible but i can understand why some people like it..."

She rubbed a finger on top the edges of the recipent and gave it a playfull look. Twilight dipped a finger in the liquid and then inserted her finger inside her mouth; in a smaller amount that covered her finger, the taste was better and more appealing for her. She had one more thing to do with that golden elixir, she tilted the recipent, the piss dropped on top of her clothes and made them look with a darker tone; i stained the chest zone of the shirt Twilight was wearing and dripped all the way down, staining also the skirt she was wearing; all covered slightly in it with a dark but also golden tone with it's caracteristic smell too.

Twilight got naked, she only kept on her socks; looking down she noticed that her body is shinier than before. "The skin is shinier than when wetting it with water... interesting" She rubbed her free hand all along her body but only where she knew that it got wet by her urine. While doing it, she felt her skin more stickier; sweat still makes the skin a lot more stickier but that was a very interesting. "Such a filthy feeling, such mess... i could get used to this" Those feelings made her submit to her most basic desires, but deeply in her thoughts she kept saying that it was for science and understanding; her most in sight thoughts were different, they kept repeating that it was feeling great and that hr body needed more and more.

But then, something broke her moment. Her phone rang, making her jump and fell on her butt; she grabbed her phone and quickly looked who was calling her. Sunset, who previously sent a message that for some reason Twilight didn't got noticed about it. With a little catch of air she answerd the call.

"Hey Sunset! How may i help you?" Twilight asked, Sunset answered but nothing to be heard by the recording; just a bit distorted whispers. "Oh geez! Was it today? Well uh... give me some minutes, i hae to take a shower and i'll be there soon with the dices" She hanged the call, and then opened the shower, letting the warm water clean her. With the hurry she grabbed the clean spare clothes she had ready and put them on, looking at the lense. "Uh... well, the experiment is a success; things about the salty and warm combination, similar to water but a little more foreing as it's not the same." Twilight turned aroud and showed that she was not wearing any panties, maybe because of a mistake. She stoped the recording and left the lab, she's getting a little unworried... should we be worried about how experimenting like that is affecting her?

Chapter 4: Lights, Webcam, Action!

Did you ever wondered where scientist get random things that they can use in their homemade experiments? No? Well, some are really well payed and they can afford things, Twilight as she got one lab from Crystal Prep practically for herself only, she had a lot of stuff that she had to bring home because they were going to change the purpose of that room; so that's the reason why she has a lab in her house and plenty things to use... like one thing for today's experiment.

In the old lab, Twilight had a spotlight; not as powerful as the ones from a stadium but enough to give her body the light needed for today's experiment. After what she did in the last one, she needed something a little more lighter to balance the things she's doing. For today; alongside that spotlight, Twilight was wearing the set of lingerie she bought for her second experiment and prepared the webcam in a very odd position while also putting her lab coat on top of that lingerie; hiding it from all view. She sat at her chair and prepared a program to screenrecord what she's about to do, as she cannot have the webcam recording and doing another thing that she wants.

She started recording. "Time for next log in lewd stuff human physche; or something like that. After what i did yesterday i think that next experiment should be a little more less... intense" She prepared a special website; and then with her microphone off she started with... a livestream. "And i'm on!" In a small window, Twilight could see what the webcam was recording; a nice view of her lab coat and the white lace stockings, nothing of the underwear to be seen.

The session started pretty calmed, Twilight waited for someone to get into the streaming room she opened for everyone; moving one of her legs back and forth in a very playful way, kinda like an invitation to join. Soon enough, someone did joined to the room, and wrote a message.

"Nice legs!" Someone wrote, Twilight couldn't tell who that one was; just that was a guy because of a little symbol aside of the nickname. "Will you give me a tease of them?" He asked politely, Twilight gave him what he wanted; moving a bit the coat showing her thighs and running a finger along them, just as she did icons of hearts popped on the chat; he was loving that simple finger movement.

Another one joined, this time it was a female. "Oh my, what i'd give to worship those legs!" She stated, Twilight got surprised to see that just a simple view of her legs was making others be interested in her. She changed her angle a little more, now both legs are visible in the webcam's vision, as soon as she changed the angle more and more people joined to watch her and her teasing attitude, many more and more were waiting to see a little more; that made Twilight arch a little smile.

"Do you really want to see more?" Twilight wrote in the chat, suddenly it flooded with a lot of capped messages that said yes with hearts and little devil faces. "Well then, you all deserved a little bit!" She stated in the chat, then she opened a little her lab coat and uncovered her breasts a little bit and squeezed them, chat went wild with her brief exposure; she couldn't know what they would be doing while watching her, she thinks that they may just be drooling for her a lot; she also couldn't imagine she could be seen as sexy by other people.

She changed her angle towards the webcam and then slipped off the g-string just to spread her legs and show her hairy slit; that view wouldn't be that hot and arousing for everyone... right? Well she was wrong, about the majority were absolutely wild about that view and the rest was unsure and confused about how to feel; just that they still had an arousal to take care off, so they stayed around admiring her, her body and the lingerie she was wearing. Twilight's face was not visible but if it were, it would show a wide smile with red colored cheeks as a show of her arousal; is actually Twilight understanding why people get aroused by things? Well, not exactly; althought she's having fun and arousing moments still does not understand what makes people go like she's currently being; her body felt in a bigger heat than in previous experiments.

Twilight's fingers slid inside her slit unsing two of her fingers for pleasing herself more. "T-this... is good..." She didn't cared anymore of anyone watching, her fingers were speeding up and trying to reach a deeper spot inside her; the chat were going really wild looking at the action of Twilight playing with herself, they could tell that she was a newbie in all of this stuff by how intense she was playing with herself; they wanted to say something about that, but... they were feeling the same way as her. Twilight then without any control, squirted really hard... for her bad luck to hit the webcam and sicne it's not waterproof, the recording stopped and the image she was streaming was no longer visible.

When Twilight recovered her thoughts on the post-climax; she realized what she did. "Ok... maybe that wasn't the best of ideas. I shouldn't have placed it in a in splash zone range" Lucky for her that it didn't splashed the computer she was using, it was on the oposite side but now she couldn't finish the log recording, so she apologized to the people that were enjoying the show by writing in the chat and stopping all. "Well now, i not only need to spend money on new items for researchs but... also on a new webcam. For being so smart i can sometimes be a real dummy" Twilight realized that she talked to herself with no one to hear her; she felt nostalgic from when in Crystal Prep she talked to Spike whenever she made a discovery. "Heh... seems like i sure have changed and at the same time i didn't. How curious"

Twilight then just started to think on next experiment, what to do? what would she feel? That is a experiment to discover another day.

Chapter 5: Just Moaning Allowed!

View Online

About a few days later, Twilight has bought a new webcam; this time a little more waterproof just in case she squirts on it again by mistake; because obviously it may happen again. For today, Twilight has brought from Cadance's house... who happens to be also her brother's house; a box full of some sort of toys that her now sister in law had in a drawer, Twilight knew that now it's a very hard time for Cadance to use any of those, because she's a little busy with her work as principal. What does this box have? A numerous variety of gag straps each unique in their own ways.

Twilight first did an important thing, connecting the webcam to the computer and checked that it recorded perfectly. "Yes! All ready for the next experiment!" She said loudly, with a wide cute smile on her face that could melt anyone seeing it. She opened the box and prepared one of the most simple gag straps on the table... the all clasic ball gag. "Recording on! And log entry number... five i guess, on kinks effect on hyman psyche; today we're going to be experimenting with what we know it is gag straps. Items placed on the mouths to not allow the user to close the mouth and mostly cause moans to sound louder or muffled and of course, we're going to try a few" She showed the first one to the webcam, leather straps, with magnets as the way to keep it around the head, easy to take off if needed and a big, with holes, red ball in the front.

Twilight opened her mouth and slightly bit the ball with her teeth, placing the magnets close to each other until... *click* ... they're together, her breath were heavier; it was a strange feeling to have her mouth forced to be open. It was a little uncomfortable to have it open like that, she tried to move her tongue a little bit, but it always were hitting the gag ball making it a little more wet; she felt incredibly good with only that ball between her teeth, all she needed left was someone else forcing more things into her. She undid the magnets and removed the ball from her mouth, a trail of saliva dripped from the ball, connecting it with the tongue.

"Wow... i'm speechless, that was great!" She recovered her breath and placed the gag at the table and proceeded to hold a different one from the box, the next one was similar in concept; but the execution was a little different: it was a single ring that kept the lips open and meant to be biten briefly. "This one looks similar but i guess that it has a different purpose i guess... let's see..." She placed it in her mouth, as soon as it shaped perfectly to it, her upper teeth bit the ring keeping it in it's place and again the magnets keeped it tight to her face; as this time the mouth was not covered by anything her breathing could be heard, it was way more heavier than having the ball blocking part of her mouth... as a downside, or not; Twilight felt how her saliva was leaking a little down her chin.

As she couldn't close her mouth, there was no way Twilight could keep the saliva inside her mouth; not interested in stopping it she just felt how it also felt a little on her shirt, staining it as it kept coming out. She felt the urge to use her fingers to play with her tongue, that was all alone there waiting for anything to play with it; and with that she rubbed the fingertip, she never felt her tongue so moisty, not even when she was incredibly hungry; but what kept her going was the fact that while having that in her mouth the only sound she was making were only moans, she was still able to talk but uncomprehensible words; so with that reasoning she preffered to only moan.... but something was missing from all that.

Twilight removed the ring from her mouth and massaged her jaw. "Ouch, feels good but... dang it is sometimes uncomfy. Now; i think i saw one that..." Twilight looked into the box and then grabbed the one that caught her eye. "And there you are!" She pulled it out, a gag-strap that had a penis shape and what it looked like a battery cavity. Twilight checked if the batteries where plugged in, and a button could be spotted aside of the cavity; they were plugged and she was ready for it to go in. "Well; you're going to be last one for today... so you better be good"

Twilight licked her lips before pushing the penish shaped gag inside her mouth, once the mangets were united it felt extra tight; breathing became even harder now that almost got right into her throat, but it was just the tip about to hit the entrance of it. She felt the urge to move her tongue around it, so she did lubbing it even when it was not going to reach deeper, she remembered the button that she saw and tried to locate it with her finger and pressed it.

Suddenly, she felt it thrusting the rubber penis back and froth inside her mouth; with that thrust now it reached the entrance of her throat and now, Twilight was back to jus tmake moans but now mixed with gagging sounds as she was not used to have a penis thrusting in her mouth; she was surprised that Cadance had that even knowing that she has Shining Armor to do whatever she pleases. The thrusts of the device were fast, enough to make Twilight feel like she was going to throw up; but luckily for her the moves were fast enough to not stimulate the point of the throat that would cause her to do so; instead those quick movements made her pussy leak a lot of juices, staining her panties and the chair she was sitting on... Twilight mouth were really loving that sensation, again all her thoughts were shutting down and just her sense of lust was able to feel something.

She closed her eyes while still feeling that gorgeous and practically perfect sensation. Then Twilight got interrupted, her phone was ringing; it was... Cadance! She quickly stopped the gag and pulled it out of her mouth; and quickly answered. "Cadance.... what a... surprise!" She said, while recovering her breath.

"Hello Twilight!" Cadance voice had an obvious upset tone. "Do you know, for not any reason in particular... where my box of strap gags is? Also, are you ok? You breathing too loudly"

"No...? I don't... uh... know. I was just making exercise; that's... why i had my breath... heavier... hehe" Twilight tried to lie, but she knew Cadance had a clue that she had them; also despite she couldn't tell it was obvious that Cadance raised an eyebrow thanks to the awkward silence. "Ok... yes, i got them; for science things..."

"Look i don't mind you taking my stuff but at least let me know via a message" Cadance letted her know that, she sighed before smiling. "I'm glad that you're finally doing that kind of things"

"You do?" Twilight asked confused about that affirmation.

"You've always been too deep into researching and grades that i barely saw you interactiong with others or interested in finding what you're into. So i hoped that when you got with your new group of friends you got more open... tho took you long!"

"Yeah, that was my mistake i guess. If i'd need something else, then i'll make sure to let you know" Twilight also smiled.

"Good, you can keep those for today and i want them back here tomorrow" Cadance demanded Twilight who agreed. "Who knows? Maybe some day i can show you things that i cannot do with your brother... you'll have to wait for that!" Then Cadance ended the call there, causing Twilight to blush deeply as that caught her off guard. She looked at the box and raised a little more pervy smile, maybe she still has some time today to play with those... the log entry lasted longer a lot longer that day; but still Twilight still needed more to research, that was still... not enough.

Chapter 6: Nothing but Comando

View Online

Early morning of a Saturday, Twilight feels like she's been drinking for hours and had a terrible headache; but nothing that she cannot fix. She prepared a coffe to start the morning awaked and warm, when she sat at the table to drink it, she took her phone to check the early morning news when something catched her attention... causing her to choke on the coffee that went into the wrong hole.

The headline read: 'Spotted Exhibitionist in the Park, people who spoted this individual couldn't identify who was making such indecent acts in public place'. Twilight wouldn't be up for showing her full body out in the middle of nowhere; but instead she had another idea, not as wild as this random person is doing but would be enough to may cause a reaction in the hormones and the brain to experiment some pleasure.

She went to her room and put on a pair of black stockings, all the way up to the thighs and took off her panties and left them on top of her bed, when she looked at the mirror, the skirt and the stockings she chose made the illusion that she was wearing pantyhose; enough for her mind to not think that she's actually not wearing anything. She took a backbag and an audio recorder so she could start and finish another of her logs in a different way than a video recorder.

"Spike, i'm heading out! Don't end all the food before i came back" She said before heading out, Spike was not that far from the door and saw underneath Twilight's skirt, his face obviously didn't showed any surprise at all; it's been nearly a week since she started those experiments.

"This girl likes to take things to the edge... and then they say that it's us animals have the wild side"


That was a very nice day to walk around, a nice breeze, sun warming the skin and just a few clouds on the bright blue sky. Twilight's plan is to go to the park and just walk around pretending to be just enjoying the day; she doesn't have in the plans to openly show her slit and rear to the people in there, but if a breeze lifts it and someone sees it then that would be more than enough of a start for her.

"Audio log entry one, subject... exhibitionism?! I don't want to count it that way as i'm not going to openly show to anyone" She whispered into the recorder. "Objective is to get a walk around the park and get back home while i don't have any panties around; i have tricked part of my mind with stockings which i know they are good for catching the eyes. I'll do my best" She stopped the recording there for a moment and went straight to the park.

She standed at the entrance for a little bit, worried and nervous; her breathing was taking over her thoughs as it was becoming a little heavier each second. Soon she stepped inside the park and as quickly as she took a few steps, a very cold breeze made its way underneath Twilight's skirts... that felt freezing and despite of her having a bit of hair on her crotch, she felt like sliding her hand over there for a second to warm it a little but that wouldn't be a very polite move at that moment, there was no one around but she didn't wanted to make any suspicious moves so she kept her walk around the park.

The walk was going good, just a cold breeze casually going underneath the skirt and some people doing sports; that was going all perfectly well... almost too well. "TWILIGHT!" Someone yelled from across the park, who has the highest pitch voice to scream to be heard like that? well of course it was Pinkie Pie. The cake girl ran close to Twilight in a blink. "I wasn't expecting you here. Why didn't you tell me you were coming?"

"It was a... last minute choice" Twilight excused herself to not lead Pinkie's little almost innocent mind know what she's doing. "And why are you here exactly?" She asked to Pinkie to know why she was there, normally for her to be at a place means that there should be a party or something, but there were none at sight.

"Me? Oh nothing, just enjoying my surroundings in complete peace and silence. Which could be weird considering that i'm mostly very noisy" She exposed what she was currently doing and surprisingly Twilight agreed with Pinkie Pie and how noisy she is in some situations, they walked for a while until they saw one free bench. "Want to take a seat?" Pinkie asked, then Twilight saw that it was a metal made bench, completely at the shadow of a tree; that means that taking seat as she currently were... would feel really cold.

"Sure, why not?" She couldn't decline it to not be seen rude, both girls sat at the bench and Twilight felt a quick but really cold feeling running up her body as soon as her lower lips and buttcocks touched the metal plate. "Geez... i wasn't expecting to be this cold today, my legs are freezing"

Pinkie giggled for a moment. "Because you're just wearing that, silly" Pinkie crossed her legs, Twilight saw that she was wearing a pair of white opque pantyhose, that made a very comfy sound among rubbing against itself.

"But you don't even have sleeves, why don't you have any cold?" Twilight tried to understand her friend's body work, Pinkie then gave her a very quirky smile; Twilight could match that smile to look like a cat. She hold Twilight by both "I must know how... i recall seeing you in winter with less layers of clothing as of everyone else"

"Heh... again, silly Twilight. I told you i have my ways" She kept that smile on her face and then looked down at Twilight's shaking legs and rubbed a hand on her thighs; Pinkie's hands were warm, not a single inch of her heand were cold. Twilight's mind really weren't understanding at all. "It's all in the fabric, you are wearing very light fabric stockings and that barely will protect you from cold breeze. Now look at mine, nothing to be seen underneath and a lot more thicker fabric than yours... i am well protected"

Twilight then checked the facts that Pinkie stablished; rubbing her hands on her stockings and then on Pinkie's pantyhose, pinching a little bit of the fabric with her fingers. Indeed it was thicker than her stockings, a newbie mistake probably. "Well... i guess i was wrong" Twilight prepared to stand up, as she was standing; a breeze flew underneath Twilight's skirt lifting it and showing everything underneath it. Her face turned red and then looked back at Pinkie who just stared at her butt. "Tell me you didn't saw..."

"Oh i definetly saw that" Pinkie made Twilight hug into her legs, but then she got recomfortated by Pinkie with calm slow palms on her back. "Don't worry Twilight, i do comando all day"

"Your do?!" Twilight's eyes widen at that declaration. "But... we though... that you..."

"That i was very innocent for these things? For being the smartest you sometimes are ver silly" Pinkie then leaned her head closer to Twilight's; she could smell the cotton candy haired girl breath, it smelled like candy. "Do you want to see?" Pinkie said in a very sensual voice, Twilight's face turned even more red; she looked more like a tomato and her voice barely could get out of her mouth to make a propper answer. "Just kidding, i do go comando but i won't show just like that; if you do again i recommend you to do it with what i wear. We could now be comando partners" She giggled and winked at Twilight, who was recovering from that sudden sensuality.

Pinkie then had to go, she had to attend at her work. Twilight then went back home, she had enough with that attempt; she might still try going without any underwear but now covering properly eveyrhting to not catch a cold; for her understanding, going comando could be really exciting for the chances of being caught by someone unknown seeing her nothingness.

Her first just audio log caught the interaction with Pinkie Pie being a completely seductive woman; Twilight edited the audio because she doesn't want her face to be turned red every time she wants to check on that log again. The following question
that Twilight did was. "What to experiment next?"

Chapter 7: The Amore Dominance

View Online

This is a completely different day, Twilight got a message from Cadance, it said "We have the house for ourselves" Twilight gulped some saliva as she stands outside of the house of her sister in law. She knew Cadance since she used to babysit her and Twilight knew that she tends to act a little strange when it comes to love or similar stuff; still remembers some of the sounds she made on some days she got dates with Shinning Armor at her old place.

"Ok Twilight, you got this!" She said to herself while taking a deep breath. "You know her, she's married with your big brother... it's a natural thing to go visit your sister in law..." Twilight looked at the house for a moment and then walked closer just to ring the bell. "... I should go back and get the recorder for the audio log..."

As soon as she tried to step away, the door opened and Cadance showed. "Twilight, you took your time to come" She joked to the science girl who was obviously really tense. "Come on in" She invited Twilight inside, who walked in with very heavy steps, as she stepped inside she noticed a very intoxicating but lovely smell inside the house; it was strawberry? roses perhaps? All she knew is that the smell made her feel a little more relaxed to the point of closing her eyes and enjoy it.

"My! You didn't had to do this" Twilight expressed with her eyes completely closed enjoying the smell of the perfumes; she was really comfy with that smell, but then Cadance closed the front door and approached Twilight from behind and cared her hands all over the side of her body. "W-wha...? Cadance?"

The principal's hand clunched to Twilight's boobs. "You've been naughty lately, am i right?" Cadance asked to Twilight with a very serene but playful voice.

"This is because of the dildos?" Twilight asked while her body started to feel in heat at the touches of her sister in law.

"Not exactly, you thought that i wouldn't have seen your little stream of the other day?" Cadance stated, sqeezing Twilight's boobs a little harder now. "You in such beautiful white lingerie... and that bush of your slit... you loved being watched by strangers?" Cadance asked once again, Twilight's breathing turned heavier as well a little moan escaped between her lips.

"It was... for the science" Twilight tried to excuse herself, but the hands of her sistr in law were something out of this world; her more experienced time in pleasing really shows, now those conversations with the family where Shinning Armor said that she was like a non-stop truck of love started to make sense. "These hands... are... Ahhh..." Another moan, now interrupted her speaking, with a little move, Cadance hold Twilight by the chinn and looked into her eyes before they shared a passionate and sloppy kiss; both women tongue action was really intense even with the fact that Twilight hasn't kissed anyone before that point.

Cadance leaned her head back before looking into the eyes of the slim scientist girl. "Follow me Twilight, this is meant to be done in the room" She hold Twilight's skirt and lead her to the bedroom, Twilight did not tried to fight back; she was just amazed by te whole self of her sister in law, that kiss felt like a car running towards her brain; shutting down all primarly inhibitions of the body and switching them to pleasure. They reached the bedroom shortly after, the bed looked like a very big marshmallow waiting to be tasted. "Here Twilight, put this on"

Twilight grabbed the clothes Cadance gave to her and checked them, she found out that there were white lingerie with holes in the thong and in the bra for the nipples, both were also accompany by a pair of lace stockings with heart patterns all over them. Twilight proceeded to put them all on, feeling really comfy and the only thing she could be missing would be a pair of elbow gloves to feel like a very rich woman acting like a total slut, but there was indeed something else she didn't noticed, a blindfold.

"Huh... what is this for?" Twilight asked confused by the blindfold, but then Cadance appeared from behind and took it just to place it on top of Twilight's eyes before she could see what Cadance was wearing. "C-Cadance? Where are you?" She moved her hands to try to catch her, she kinda knew that she wouldn't be able to take it off.

Then the scientist hand landed in a soft and squeezy zone, Twilight squeezed it for a moment to try to guess what it was; she got it clear as soon as she did a few more squeezes. It was Cadance's huge breast, compared to Twilight; she were no match for the huge ones her sister in law had. Cadance letted out a soft moan at the touch of those sweet squeezes, that caused Twilight's cheeks to blush intensily red before she got grabbed by the wrist and being layed on top of the soft bed that the room had.

"My my.... you're naughty if you grab someone's breast without permisson" Cadance whispered to Twilight's ear before kissing her neck while also caring the hands on the scientist's cheeks. Twilight felt those touches more intensely, maybe wearing the blindfold made her body feel more sensitive to foreing touches; Cadance's hands felt really playfull, more than she could ever do with herself. "Let's see what you are hiding... here!" She stated before rubbing a finger between Twilight's slit, the fact that the tongue had that overture for fingers to run along it was a really great touch; Twilight only had one question, why does she have lingerie of her size?

"Wait... i am..." Twilight felt how one of Cadance's fingers gor inside of her slit, a loud moaning escaped her mouth before she could finish the sentence. "... sensitive there" she stated to her old babysitter, a big mistake for Twilight to say that to someone that already knows female bodies and their pleasure points. Cadance arched a big smile before continuing to rub her finger inside all over Twilight's inner pussy walls, moaning getting more intense. "I had to say it... didn't i?" she thought to herself, really not the smartest move she could do.

"Don't worry Twily, this is just the beggining!" Cadance whispered into Twilight's ear before putting cuffs on her wrists, while also being tied to the head of the bed, Twilight could hear the sound of something metalic, but couldn't recognize it. Then, she felt something round against her pussy lips, very cold. "It's good to use them with your own hand but... it's better to feel it with a little harder thrusts" Cadance hold Twilight's thighs and then pushed her hips, Twilight now recognized that it was a dildo, a very long one that reached her womb in one go.

Twilight's eyes widen, but it was not possible to tell because of the blindfold; she only felt Cadance moving her hips back and forth constantly hitting her on the entrance of her womb. She couldn't stop moaning, that really was hitting her insides hard but in a very pleasing way. All she could do was just moan and bit her lips while Cadance trhusted her hips with a very consistant hips speed, Twilight wanted to remove the blindfold to see what Cadance was doing and what she was wearing; but it was no possible; unnable to see what was going on her body felt in more heat than before and with her pussy leaking a lot of juices staining the bed sheets underneath her.

Cadance thought that her loud moans could disturb the neighbors, so to keep her shout in silence, she proceeded to kiss Twilight in her lips while also digging her tongue inside of her. The playfull tongue from Cadance was really hard to keep track of; like it has it's own life, it played with Twilight's tongue twirling around and teasing every inch of it, making a saliva mess. Twilight couldn't handle such magnifficent display of pleasing skills, Cadance level was way higher than hers... how long could she hold herself? Well, in fact it was not tood long, Twilight's body shaked shortly after all tose mixed feeling over her body, the dildo, the blindfild and the tongue kiss, Twilight squirted all over Cadance's crotch and bed sheets staining them in all of her juices.

Cadance leaned back, giving her space to catch some air, panting hard. "Twilight, you did a really big mess. You're so naughty"

"And who fault is that?" She asked, a little annoyed because she wanted to see the action.

"All yours Twily" Cadance giggled before pulling the dildo out of her siste in law's pussy. "But you've made a really big mess, so wait here while i take a shower. After that i have to go to a meeting"

"Wait... you can't leave me here just like that!" Twilight demaned to get untied, but no response to be heard. "Cadance?... Hello?" She was left alone in the room, wrist with cuffs and unnable to leave. Well good news are that she won't forget to write a log about being dominated by someone that became part of your family... that's for sure.

Chapter 8: Dirty Daring Scientist!

View Online

Twilight walked around her house, checking her notes in the notebook about her experiments; the latest with Cadance; even tho it was pleasuring, it was similar to something she already did in one of the latest experiments... after all it was including dildos, but being dominated was a different thing and she loved it. As she was walking without paying attention, she stepped into something squishy, but she didn't had any carpets around and it was not one of Spike's squeeky toys.

She didn't wanted to look but had to, she did... she stepped into one of Spike's feces and it was really recent. "Oh come on! Spike! Didn't i told you to do is in the backyard?" She got no response from Spike at all and didn't wanted to step her feet back on the floor, lucky for her she was using old shoes that needed to get to the trash anytime soon. "Spike? Ugh, can speak but can't take a dump in where i taught him to"

As she was looking at it, she recalled on something. There were people that for some reason is turned on by that, touching, eating or simply just letting it all out, now this was more interesting to experiment about; she has a shower ready for it in case she'll need it and definitely she will.

Back to routine, webcam ready, all clothes off except for a pair of black stockings; in case of something being stained then it wouldn't be noticeable; Twilight turned on the webcam, seeing her whole body naked in the monitor felt nostalgic as she didn't recorded with this in the last experiments. "Well, finally back with a video log! Oh i missed it so much" She said with an eager feeling of happiness... her being eagerly happy about recording herself doing naughty things? Doesn't look like herself, looks more like her new self. "Today's log will be a little nastier... well a lot more nastier; as i'm only wearing black stockings, i'm getting mentally ready to... touch and do stuff with poop"

Twilight gulped a bit of saliva, anyone with their minds in it's place would never attempt something like that on purpose, in fact it probably became a thing because of accident. Twilight hold the webcam and placed it in front of the shower, it was prepared for recording, to have a good angle she placed it on top of numerous books.

Twilight tried to place herself at the most comfortable position she could and spreaded her legs widely, her pussy completely exposed and slightly underneath it's her butthole visible for the device to record it. A full nervous feeling run through all the scientist's body, she wasn't really sure but science needed to prove more stuff, even if it is a little gross.

With a deep breath, Twilight twilight started pushing with her tummy, small farts escaped as she was pushing until a wet sound has been heard and a bit brown head was making its way outside of her butt. "Come on... get out!" She said while keeping her focus on pushing it out, arching a little bit her body at the feeling of that huge log comming out. It fell into the shower floor and rolled a little until hitting Twilight's ankle. "You were a hard one to push out... dang it!" She looked down at the turd, it was a really solid one and had a strong smell.

With a little bit of doubting, she hold it with her hand; it felt warm and a little bit slimy. She shaked it a little in her hand checking it's texture and overall sight of it. She was not completely sure about it, it was not completely appealing to her; but then as she was shaking it it slipped down her hand and fell between her breats, perfectly slipping between her cleavage. The slimy and warm feeling of that turn going between her breasts were not as she imagined, it was actually stimulating causing her breath to become heavier, quite the surprise.

"Why?" She whispered as her breath continued to become heavier. "Why am i being turned on by this?" All her mind was doing was trying to find any sort of sense to understand why that filthy and disgusting element was turning her on, the old her from a few weeks back wouldn't have accepted to do something like that and even less loving the sensation... but that was a new her, open for new sensations. "More... this is not enough for experiment"

But there was an issue, she dumped all she had; or that's what she'd like to thought. Nearby her there was a little bottle of laxative, she had it for emergencies with a fast action of practically seconds; but this time and for experimenting she did had to use it, with her hand shaking violently she hold the bottle and after removing the cap she took a little sip from it; it tasted horribly with a touch of salt to not make it taste that bad... it doesn't work at all, tastes like a forgotten plastic bottle of water in the sun for few days; how did she knew how that tasted like? That's something she doesn't like to talk about.

She felt the effect a minute after she took the sip, placing a hand on her tummy for a second and closing her eyes to focus on the second push. It was a little bit quicker than the first one, also a little less solid that it also helped with it's push out; the smell filled the room a little more; with a little carefull, she leaded a hand towards the pile that were laying underneath Twilight's butt, to her touch it had a very warm sensation mixed with a little bit of sticky sensations. Slowly, she lead her hand towards her mouth and with a soft tongue movement she licked the fingertips to have a taste of the disgusting turd she pushed out of her butt.

She disliked the taste of it, fully disgusting but for some reason... she got her slit wet after licking that; she deeply liked the disgusting taste? Yes! She did liked that taste despite it's disgusting nature; what followed that slight display of taste were a little more focused on her body as with the palm of her hand, she rubbed and spreaded it on top of her body along her breasts, belly and crotch obviously looking for the maximum pleasure from the overall feeling of it covering her body; in her mind she was repeating the phrase "All for science!" but her face said that she was a bit of a hopeless pervert that cannot turn back to her ussual self, well she can do it in a snap of fingers; but as she keeps playing with herself in deeper and more kinky fetishes her mind loves all the found sensations.

But that unique kind of fun had to end at some point, Twilight turned on the shower and just let the water do its job wetting her body and cleaning it up. "I feel so dirty... but i enjoyed it" She whispered underneath the water, the brownish stains left her body to her ussual purple skin tone; the pile she left on the shower floor also melted away, to help the smell to leave she used a special body wash that smelled like flowers, more precisely to roses. "That's much better, that was ok but not my thing... but i wouldn't mind giving it more tries if needed" She told to herself as she touched herself with the body wash while also still keeping the stockings wet under the water stream; as she felt extra dirty that day some shower play wouldn't hurt her, all she needed whas to think on what she would go for next... she already has an idea on what to do and who will help her next time.
