It has been a few years since Twilight Sparkle first arrived in Ponyville. Twilight has since become sexually frustrated and afraid to be open with her friends in any sort of direct way. Spike has been observing Twilight over the years and fears that her magic has become too powerful for her own good, thinking that she is above Celestia’s rule because of her power. To make matters worse, a recent incident caused Twilight and Spike’s relationship to tread on thin ice.

Chapter 1 - Dragon Juice

It was going to be another one of those days, Spike thought as his eyes opened, despite being well rested from a wonderful night of sleep. Pushing his sheets to the side, the young dragon got up out of his basket. In his experience nothing good came from waking himself up. After all, it was Twilight’s job to regulate the growing dragon’s sleeping patterns.

Sure enough, as Spike approached his friend’s bed, no purple unicorn was present. The bed was in perfect shape, the sheets still grasped tightly on the sides in a neat manner. It had always been the young dragon’s job to make the bed and it being already made could only mean one thing.

“Oh no... Twilight’s been up all night experimenting with spells again.” Spike uttered audibly to himself. He wasn’t going to let it bother him, after all it was time for breakfast.

Deep beneath the Ponyville library, Twilight was hard at work. She was in the corner, standing in front of a book, struggling to read at an adequate pace. Her eyes were weary from sleep deprivation, and the tables around her were littered with glass containers filled with a myriad of chemicals. The disheveled pony stood beside a half-filled bucket of water. On the table nearest Twilight, a clear container held a clear mixture with a slightly yellowish tint.

Twilight’s horn glowed as she used her magic to turn the page. It had been a long night, but she felt that she had learned what she had wanted. In between her flanks there was an uncomfortable feeling of dampness that ran down both of her hind legs. All four of her hooves soaked in a stagnant liquid that was present across the floor. The sharp scent that filled the air was now almost unnoticeable to the unicorn due to the sheer amount of time she had been working in it. Though she was uncomfortable, Twilight couldn't help but smile at her success.

Twilight’s head perked up as she heard the sound of the laboratory door opening. Spike was awake. Concern swept over her body, as she realized she didn’t want her friend to see her like this. Almost immediately the unicorn’s horn glowed, enveloping the liquid on the ground. Her concentration and understanding of the composition of the wooden floor allowed her to levitate the puddle, grasping almost every drop from inside the pores of the wood. She began to magically channel the liquid into a nearby container. Tiny footsteps grew louder and louder, as she heard her assistant walking down the stairs. As the last of the liquid from the floor made its way into the container, she now focused on her backside. Because of the limited time she had, Twilight failed to pick up the deeper stains on her fur. As quickly as she could, Twilight used her magic to levitate what excess liquid she could pick up off her body and floated it into the container as well. Though residue and some dampness still remained on her back legs and hooves, she clamped the cover onto the container to lessen the strong odor present in the room.

“I knew you would be down here,” the green-eyed dragon said with an almost defeated tone as he approached his friend. “What are you working on this time? A spell that makes ponies invisible? A spell that makes gems from water? A spell that lets you make food flavored water? A spell that makes ponies' heads explode!?”

“Umm...” Twilight struggled to decide if she wanted to tell him what she had been working on, given the unfortunate implications. “Well... I’ve created a spell that allows me to directly grasp and teleport liquids in and out of precise locations.”

“Oh please tell me this spell has a use that isn’t going to get you into trouble... Don’t you remember what happened last time?”

“Come on Spike it wasn’t that bad, sure being able to manipulate the contractions in the muscles of a pony directly using a spell based on my understanding of neuroscience might sound evil, but I was going to use it for noble purposes.”

“Noble purposes? The first thing you did with it was make Rarity fall over her hooves, horn falling directly into your-”

“Shush Spike, you weren’t supposed to see that. It’s bad enough you sent that letter to Princess Celestia.”

“I was just looking out for you Twi, did you see how embarrassed Rarity was? She thought it was her fault that she had an unfortunate encounter with your...”

Twilight suppressed a blush as she thought about the incident, chills went down her spine as she thought about seeing her friend’s horn glistening with the liquid of her excited marehood.

“Well you didn’t have to tell the Princess about my spell, I had to pretend to go along with her idea that the spell was ‘too powerful for any one pony to posses.’ How would you like to have your brain probed by that brute!”

“Twi, listen to me. If you used that spell any more on your friends, you would have lost them when they figured out you were manipulating them. It’s even worse to think you were manipulating them for some kind of sick pleasure. Fluttershy must have died of embarrassment when she ‘accidentally’ slapped your ass with her hoof, what would ever possess her to do that? Oh that’s right, her 'innocent' purple friend would.”

“Ahem Spike, please. I don’t like your condescending tone. My experiments deserve at least a little amount of respect. Now can we please move on, that spell is over and done with and I can never do it again thanks to you.”

“Alright, so what is the practical use of this new spell? What could you possibly gain by being able to teleport liquid?”

Twilight had planned for this if anypony asked, she just hoped she could get away with misdirecting her number one assistant. “Well you see, Spike. I have often come across the problem of staying hydrated while doing strenuous activities. When I first did the running of the leaves, I was dying of thirst by the end of the race. With my spell I can simply carry a container of water in my saddle bags and teleport it directly into my stomach.”

“That is... useful?”

“Observe.” Twilight’s horn glowed. The bucket of water on the side of her emitted a magical light as a globe shaped glob of water floated out of the bucket. “12 ounces of water... just enough to hydrate your small body.” The floating water shook violently in the air for a second and then disappeared.

“Huh... where did it go?” the dragon said in a flustered tone.

“It’s in your stomach, can’t you feel it?”

“I don’t feel anyth- Sweet Celestia it really is in there!” Spike shouted with an impressed look on his face. He felt a relaxed weight as the water sloshed around in his stomach.

“Not only that but I can...” Twilight’s horn glowed but no object around her emitted a magical light. “...remove liquid as well.” she stated with a grunt as the water she had placed inside of her assistant appeared in front of her, suspended by her magic. It had changed from a clear liquid to a cloudy mixture from the bile it was introduced to inside the dragon’s stomach.

“Think of the possibilities, if a little filly drank a poisonous liquid I could easily extract it with no pain!”

“You can’t extract... blood... can you? This isn’t dangerous right?” the inquisitive dragon asked, now suspecting something had to be off about the spell.

“I can remove blood in small quantities, not enough to cause more than a feeling of being lightheaded.” The purple mare grew slightly nervous, hoping her friend was done with the incriminating questions.

“Alright, well it sounds like a cool spell...” The dragon’s eyes somehow found their way to unicorn’s rear legs and noticed their distinct darkness, almost as if they had recently been wet. “Say Twi... you weren’t so engrossed during your studying that you didn’t bother to take a break to use the bathroom, right?”

Why doesn’t this dragon mind his own business? Twilight cursed to herself, hoping her assistant can’t put two and two together.

Spike's eyes lit up as a look of horror came over his face. The awkward silence in the room was instantly broken.

”Nonononono... NO Twilight, NO!” Spike yelled as he realized Twilight’s true intentions. “No more of these spells that fuel your sick sexual desires!”

His words were painful to her. She never had the courage to directly fulfill her desires with anypony, afraid to ask what any of her close friends do to relieve their libido. She didn’t think any of her desires were misguided or wrong, but the fact that her intentions might hurt others still stung when Spike called her out on it.

“I’m really sorry Spike... I didn’t really want you to know about my... enjoyment... of urine. I mean, almost all mares like to pee and it is especially arousing for the stallions. I feel it is a private matter, you know.” As she spoke the words, her closeness with her assistant didn’t stop her from blushing. She found it funny that a simple natural urge could be so offensive to her friend and at the same time cause her to feel embarrassed.

“The truth is... I found a marefriend who enjoys partaking in these kinds of activities with me and I thought It’d help us both out if I developed this spell,” she lied. All she could do was pray to Celestia that her lie would come true before Spike found out any more.

“Alright, I’m sorry too, I didn’t mean to accuse you of doing anything wrong. Prying into your private life wasn’t what I was trying to do, I guess I am a little weary because of what you did last time.”

“I was hoping you would have forgiven me for that, It was a lack of judgment on my part. I wrongly viewed my friends as test subjects without any consent. You did the right thing. If I continued to use that spell I probably would have lost my friends.”

“I told you I forgave you before, Twi. Can we please go back to our old assistant-scientist relationship?”

“Of course,” Twilight said, sincerely happy about the release of tension after so many months, even if it did come about from lies. Twilight was content with the renewed sense of trust between them.

“It’s kind of embarrassing...” Twilight hesitated, “but can you help me finish up my spell?”

“...” the dragon had no words to say to such an asinine request.

“Please?”

“Alright... I guess I have to bite the bullet If want to keep being your assistant, don’t I.” Spike talked with a weary tone, hoping what was about to transpire wouldn’t be too much for him to take.

“Thank you. You didn't pee this morning, right?” Twilight tried to keep the words casual, even in their awkward glory.

“...No,” Spike said with a feeling that this was about to get awkward.

“Alright,” Twilight said, horn aglow. Two glass cylinders floated through the air, propelled by Twilight’s magic. “Could you please urinate in this glass for me? I need to test the effects of direct bladder insertion of my mixture. I would do it myself but my bladder’s chemical makeup will be off for a while due to the experimenting I did last night.”

“Sure thing Twi, lemme just run to the bathroo-”

“Oh come onnn Spike, you act like I’ve never seen what hides under there before. We have been living together for years, I’ve seen you doing enough things with that thing while whispering ‘ohhhhh Rarity’ under your breath. Peeing in front of me is no big deal!”

Spike shrugged, not caring to resist any more. He pulled his dragonhood from beneath the flap of scaly skin that covered it. Twilight watched with excitement. There was something about the fact that her longtime friend was comfortable enough to pee in front of her that made her happy.

A stream shot from his urethra, its golden color splashing against the wall of the cylinder. Twilight could barely resist the sight; she had butterflies in her stomach, as pressure built throughout her body. Steam rose out from the cylinder when Spike’s urine began to pour in. The strong scent of pee penetrated Twilight’s nostrils. She felt overcome by her desire causing her privates to start to self-lubricate. Drips of mare juice started to dampen her labia. Her entire body screamed for Spike’s dick to be penetrating her.

Spike didn’t really know what to feel, it felt strange to him. Peeing in front of a mare was something he had never done before. The more he thought about Twilight’s eyes staring, the more odd he felt. He couldn’t grasp what was happening in his body - it almost gave him a peculiar sense of excitement. The young dragon’s stream of pee started to slow down as the final drips splashed into the glass.

“Thank you...” Twilight said, still horny as a moose. She used her horn to magically grasp the glass filled with the amber colored urine, and floated it over to her worktable.

“Arlight. Now I’m gonna do almost the same thing as before... but this time I’ll be teleporting this chemical solution directly into your bladder. When combined with the natural chemicals still in your bladder, the solution of urine should smell, look, and ta- I mean have the same consistency as your first pee sample.”

Twilight's horn glowed as the vat on her workstation began to shine with the familiar magic color. “10 ounces, exactly the amount that you just gave me.” Twilight said as the globe shaped liquid rose out from the container. A small reaction later and the globe disappeared.

Spike quickly moved his claw under his stomach. “Ohh man, I really do have go again!” He exclaimed as he casually grasped his penis and started peeing. Once again the unfamiliar sensation coursed through his body. He couldn't quite put his claw on it, but whatever it was, it almost made his member transform out of its state of flaccidity. The stream of urine was finally depleted. There was no hiding Twilight's urine lust, her face told the tale. The two friends exchanged awkward glances as they tried to guess what the other was thinking. Now that cylinder was filled, Spike could see that his second wave of pee had exactly the same tinge the first unaltered morning pee.

“Thank you soo much Spike.” Twilight tried not to sound too excited with her words as she was still trying to stop herself from getting on her back and rubbing her privates. “It seems like my experimenting paid off. I’m gonna... uhh... drop some color reaction tablets into your sample to see how close their general makeup is. If it isn’t too much to ask, could you make me some breakfast? I’m starved, I’ll take you out for dinner later.”

“Sure thing Twi,” the dragon agreed, unsure how to feel after all that was revealed to him this morning. He thought about Twilight, wondering if she really had feelings for him. He also was wanting to know who Twilight’s new marefriend was, but felt that asking would overstep his bounds now that he knew what they would be doing together.

Twilight’s heart raced in anticipation. Her libido was overpowering, almost feeling like her entire body was about to spasm as Spike slowly walked up the stairs. The door to the laboratory shut tightly as her assistant walked out.

“Ohhhhh... Glowing moonbeams of Luna!” Twilight uttered in a relieved tone. Her horn glowed, opening a nearby cupboard. A cucumber rose out, floating in the air beside Twilight. Her magic was now focusing on a new area, causing the two cups of dragon urine on her workstation to float in the air, taking their place next to the phallic vegetable.

Trotting up to the wall with both the urine and the cucumber, Twilight plopped down on the floor. She placed all three objects down next to her. Twilight was now laying on her back, using her front hooves to push herself closer to the wall. The purple unicorn positioned herself so her flank was raised in front of her, back legs riding up the wall. Once she was able to get a clear view of the parts that made her a mare, she realized that she was relieved that she never had to turn around in the presence of Spike. If her assistant had stolen a glance at the action going on between her flanks, he would have noticed the tell-tale liquid of arousal dripping from her mound. That same liquid was now descending her lower stomach, with the dark wet trail soaking into her fur. She had one more thing to take care of before she was able to get to the big event.

Twilight felt the beginnings of the feeling of having to pee. She had been up all night, and the last time she tried the spell on herself was hours ago. Twilight had finished up her night by attempting to learn how to suppress the visible magic field around the subject she was targeting with her new spell. She was successful when she had found a way to precisely target the cavity inside the entity she wanted the liquid transfer to, which would shine internally, giving the pony being targeted no warning of her spell. Now the real test was to see if she could induce urination by overloading a bladder.

Through her research, Twilight found that a pony of around her girth was able to comfortably control 24 ounces of liquid inside her bladder. She figured that if there was anymore, an uncontrollable spout of deliciously arousing piss would occur.

She felt incredibly naughty as she raised the contents of the first glass of Spike’s golden liquid from the glass. The perfectly globe-shaped ball of urine hovered over Twilight. Her body throbbed nervously, loosening her grip on the pee ball. It started to drip like a popsicle in the sun. A drip of pee splashed onto Twilight’s stomach. The impact of the warm yellow liquid dampening her fur, created a sense of excitement. A second drip, even larger than the first, splashed against her upper chest, wetly rolling down to her neck due to her position against the wall. She allowed the ball of liquid to hover in front of her face as the scent of her friend’s urine penetrated her nostrils. She stuck her tongue out, making contact with the floating ball of pee. It wasn't enough for her to only allow the tip of her tongue to taste Spike's juice, she had to give the sphere a slow and gentle lick that would cover the entire outer surface of her tongue. The new and unique taste that danced upon the area of her taste-buds only fueled Twilight's arousal. Spike’s salty and warm piss had a tangy flavor that varied greatly from her own urine. The idea that everypony's urine tasted different sent shivers down her spine. Now that Twilight had gotten a taste of it, she started to concentrate and allowed the urine to teleport into her bladder.

The mare felt the added pressure in her bladder almost instantly. Mare juice was practically flowing out of her pussy as she realized both her and her friend's urine were now joined together to create a new liquid. She still felt like she needed more. The added pressure in her bladder made her feel like she needed to casually walk up to the bathroom (either that or run to one of her friend’s houses and pee all over them while they were sleeping).

It was now time to brace herself for the main event. Twilight knew that by adding ten ounces of Spike’s urine to her already full bladder would almost instantly cause her to squirt with the pressure of an orgasming stallion. Sweat dripped down her forehead as she used her horn to magically lift up the contents of the second cup of liquid containing the dragon juice. In an effort to taunt herself even more, she allowed the second liquid globe to float around her privates. Its gentle presence graced her labia, soaking the fur around it with the warm liquid. A hot wave of pleasure came over Twilight as she allowed the ball to touch her clit. Using her magic, she was able to shape the floating urine, changing it from a globe shape to a rounded rod. She inserted the floating piss rod into the insides of her slit. Her private mare-walls picked up some of her closest friend’s pee. The new urine introduced to her cunt mixed with her natural lubrication prepared herself for the entry of a large phallic object. What was left of the dragon’s piss after pulling the liquid rod from her pussy now started to shake as she performed her spell. It was gone in an instant.

This is it. The pressure in Twilight’s bladder was at the maximum level. She wouldn't be able to stand it for any longer. It felt as if she had not used the bathroom in two full days. Any second now she was going to burst. If she moved even an inch she knew the gyrations in her body would cause her to start squirting. She had to concentrate. Her libido was at the highest it had ever been in her entire life. Before this, the closest she got to a horniness of this magnitude was when she used her hoof to rub her privates while urinating on one of her friend’s socks. The combination of two forms of pressure could be felt throughout her entire body. On the one hoof, she felt that if something doesn't enter her pussy in the next five seconds she was going to get back up on her hooves and start humping the edge of her workstation. On the other hoof, the pressure inside her bladder caused a combination of nervousness and arousal that could go off at any second.

With as much concentration and as little movement as possible, Twilight used her magic to float the cucumber in front of her nether-regions. It softly touched the entrance as she braced her body for the big moment. She didn't really know if such a large object entering her was going to hurt, but she felt confident enough to try. Her lack of experience with stallions was to blame for any second thoughts now crossing her mind.

With great force, Twilight used her magic to thrust the large vegetable into her throbbing cunt. She felt like her bladder literally exploded as a torrent of pee squirted with goddess-like pressure from her peehole. A huge combination of pain and pleasure was felt through her entire body as the large cucumber was enveloped by her marehood. The spray of piss went everywhere in a broken stream. Because of her position against the wall, her pussy was focused directly at her face. The main stream of her flowing pussy splashed against her nose, making piss run messily down her cheeks. Her mouth was wide open in an instant. She yearned to taste her own urine from the running spout, having her friend's urine mixed in only sweetened the deal.

The torrent of combined dragon and pony piss splashed forcefully onto her tongue. She was tasting her own maretorrent, its warmth caressed her throat while she drank it like a thirsty race-pony.

She felt the first orgasm with three forceful pumps of the cucumber. A huge wave of pleasure rumbled her pissing body. Somehow the fact that she was covered in a certain dragon’s piss as she felt the orgasm made her feel divine ecstasy that she had once only dreamed of. Her piss was everywhere, It soaked her face, it soaked her hair, it lingered in her mouth, and her messy vag let it leak down her stomach in great volume.

Twilight wasn’t done. She had been virulently pumping the vegetable in and out of her cunt even through her feelings of weightlessness during her explosive orgasm. It was painful she had to admit. Using such a large object for her first penetration was a miscalculation on her part. The large vegetable made Twilight feel like a strong pony, able to balance the pleasure and pain of her act of masturbation. If the pain did anything, it made her feel alive. She wasn't going to quit, it was time for a second orgasm.

The thought of her friends covering her with urine crossed her mind. She thought of her five friends crowding around her, pulling back their pussy lips and starting to let their streams flow onto her. Twilight's fantasies continued, imagining Spike’s dragon cock pounding her lovehole while they both embraced each other’s pee soaked body.

The mare covered in urine, sweat, and her own secretions exploded once more through the help of a final thrust from the floating cucumber. She collapsed to the floor unable to support herself during the orgasm. Marecum flowed from her cunt as she lay paralyzed from pleasure, soaked in her and her assistant’s piss.

The wave of pleasure made her feel better than she had ever felt before. From that point, the piss soaked unicorn was glad she still had her friends. She had truly come to terms with the wrongness of her previous actions. She was happy that Spike was there to be her level-headed assistant. Now the only thing she had to overcome was her new spell. The idea of making ponies urinate on command was a power of great magnitude. It was up to her to use it for ‘noble’ purposes, as her assistant put it.

Twilight Sparkle trotted into the kitchen, feeling fresh after washing all of the delicious piss from her body in the shower. While showering, she had once again practiced her spell, filling her bladder with water and satisfyingly spraying it out into the drain. She always giggled like a school-filly when her plans came to fruition; It was so much fun for her to be able to pee over and over again.

“I don’t know why you felt it was more important to take a shower rather than eating your breakfast, it’s not like that little bit of dried pee on your legs would have made you too uncomfortable to eat. Now your eggs are cold.” Spike was annoyed at his housemate’s frustrating logic.

“I’m sorry Spike, I feel the need to be presentable in the morning.” Twilight said, biting her scrambled eggs that had long since had lost their warmth. “I have to help Applejack with her personal garden today and I might stop by Fluttershy’s place to see if she wants to help as well.”

“Sounds good, I’ll stay here and watch the library.”

“Say hi to Rarity for me, alright.”

“How did you know I was going to Rarity’s today?”

“You just told me.”

“Oh...” Spike blushed in embarrassment.
