[My Little Pony] Fucking Ponies Raining Love Ep 15.5
by @silvergunner
***

The sun rose over Ponyville as dawn broke across the land. Many ponies were getting up after a good night’s sleep, except for a few who didn’t for various reasons. Be it late homework by the Cutie Mark Crusaders, Scientific Experiments for Dr Whooves, Vinyl Scratch producing new songs, or just considering their life and where they were going in it. The Pink Earth Pony who lived and worked at the bakery fit into the latter category that bright morning as the sun shone into her bedroom on the top floor.

For the past few weeks, Pinkie Pie had being in a strange sort of relationship with Twilight. She had roleplayed being Twilight’s sex slave one evening to begin with, and was used in a way they both enjoyed by her roleplay mistress when it happened. Things had accelerated since then, and every so often Twilight Sparkle came along and used Pinkie as her sex slave whenever she wanted, and Pinkie was happy to allow Twilight to do whatever she wanted to her. Pinkie had thought until now it was just a sexual game between them both, but now she felt things were more than just that.

Rather than anticipating every time Twilight used her as a slave simply as if it a bit of fun, she was anticipating it on a more personal level. She never got more pleasure from anyone but Twilight, and she thought that the times she spent as the Alicorn’s slave were the best moments of her life. Especially when her mistress carried out some sort of act involving the kink both of them loved...

She laid back in anticipation of her mistress arriving that morning. Usually Twilight started their mistress and slave game while Pinkie was still asleep, so the pink earth pony woke up to Twilight using her in some way. Even when Twilight didn’t have any desire for long intense sexual interaction with her slave, she always visited Pinkie Pie every morning. However when Twilight finally came in after what felt to Pinkie like hours of waiting, she was surprised to see Pinkie was already awake. “Good morning, slave” the purple pony princess smiled at Pinkie.

“Good morning, mistress” Pinkie smiled. “So, what have you got planned for this morning? You gonna wet my bed for me? Soak my clothes and make me wear them? Make me take a nice hot piss bath? Or just have me drink your pee?” she asked, remembering all the times her and Twilight had engaged in their favourite kink - Watersports.

“Well, last night I thought of an experiment we could try on you today” Twilight said. “However, we both need really full bladders, so we are both gonna hold all our piss in until this afternoon, and drink lots to add to it” she commanded.

Pinkie’s face fell. “Aww, I was hoping you’d piss all over me in some way this morning. I waited all night for it...” she commented.

“Pinkie... you wanted me to pee on you?” Twilight gasped. “I always thought you only let me do it out of respect for me...” she questioned.

“It means more than that to me, Mistress” Pinkie smiled. Before Twilight could ask what she meant by that, Pinkie jumped off her bed. She clutched her loins, feeling her bladder already full, but knew she needed to hold it for later. “Come on, the bakery is closed today, so we can start drinking some lemonade together” Pinkie suggested.

“I’m the mistress and I give the orders, slave” Twilight replied. Pinkie gasped and closed her mouth, making a zipping motion, suggesting she was not going to speak. “However, your idea has merit, and we shall go and drink some lemonade together” she smiled.

A few minutes later, both ponies had gone downstairs and were now in the kitchen. Pinkie was struggling to contain her bladder, her hind legs crossing in an attempt to hold it all in. However she happily prepared a breakfast of cupcakes for her and Twilight, and pulled out of the fridge a half-gallon bottles of lemonade for them each. As she carried the lemonade into the lounge, she remembered the day from a few weeks ago when she had emptied her bladder into a lemonade jug and drank it all. That was a fun day, as it ended with her mistress and her friends using her sexually...

The morning was spent chatting and drinking lemonade. Both mares were squirming a little, but their stretchy bodies were handling the contents of their bladders pretty well. A few weeks ago, Twilight had asked Trixie to cast a body elasticity spell over both of them, so that their innards could expand to extra capacity rather than burst. It was a popular spell in Ponyville, especially with both male and female size queens who had one night stands with the most endowed stallions around the town.

Twilight herself had experienced the virtues of various stallions around Ponyville, but she never really felt anything towards them both before and after the casual sex she had with them. Until she had taken Pinkie as her roleplay slave, she never got any real sexual pleasure from anyone. Pinkie was different, and Twilight felt it wasn’t just because she was her slave, but there was something more to it. Twilight started to wonder if she had fallen in love with Pinkie. However, she managed to purge these thoughts from her head as they had an experiment to carry out that afternoon.

However what couldn’t be purged was the topic of conversation. Twilight and Pinkie were talking about their days when they were young, By coincidence during a discussion about their ventures into the Everfree Forest, Twilight mentioned she used to pee outside while nobody was looking. This reminded Pinkie of the time a few weeks ago that Twilight dared her to empty her bladder into a bucket in full public view. She loved that thrilling experience, and it had ended up a great day for them both as things escalated that past evening.

All through their conversation, Pinkie kept staring at a large cardboard box stood in the corner saying “Top Secret”. She figured Twilight had brought it along with her for the “experiment” she had planned. Pinkie wanted to ask about it, but figured that letting Twilight keep it a secret would make the experiment after Noon a lot more fun. Instead she continued the chat about their school days in Ponyville and Canterlot.

Suddenly, the clock rang twelve times as the time reached Noon, and Twilight stood up from her seat. “Its time to get started, Pinkie” she said to her friend. “Bring the pool up to your bedroom, while I bring the experiment apparatus up as well” she said. Pinkie nodded, then got the rubber paddling pool out of the cupboard along with the hoof-powered air pump used to inflate it. While she pulled both up the stairs, Twilight followed her upwards using her magic to levitate the large cardboard box along with them.

Once they got to Pinkie’s bedroom, Twilight shut the door behind them. “So why are we in the bedroom, mistress?” Pinkie asked. She had placed the deflated pool on the floor and attached the air pump to it, and was stamping gently on the pump pedal to steadily inflate the pool walls. The pool was originally purchased by Pinkie Pie to be used by the Cutie Mark Crusaders during hot summer days, but Pinkie had began using it whenever watersports were on her sexual agenda. It helped keep the floor dry to an extent at least.

“Its early, and we can’t risk any ponies finding out...” Twilight started. “...apart from two of our friends, who I think you’ll enjoy today” she added.

“Which of our friends this time?” Pinkie asked, continuing to inflate the pool using the air pump.

Suddenly the door banged open. “We’re here!” came a bright voice that was instantly familliar to the two ponies. Derpy Hooves walked into the room with a smile on her face. “I brought a friend with me Twilight. Someone who hasn’t tried this stuff before” she added. She then stood aside, and a blue pegasus walked in with a grin on her face. “Rainbow Dash is tonight’s guest” she added.

“Nice to have a new partner for our private parties” Twilight smiled. “So Rainbow Dash, why do you want to try doing watersports with us?” she asked.

“Well, I recently found that peeing during masturbating felt really good, and after looking things up on the Ponynet... I sort of became addicted to playing with my urine” Dashie admitted. “When Derpy made some casual suggestions that you had the same interests, I jumped at the chance of joining in” she grinned.

“Its great to have another friend involved in our group” Twilight smiled. “Derpy, I assume you had Trixie put the body elasticity on her?” she asked the grey pegasus.

“She did, and it worked perfectly” Derpy smiled, pointing at Rainbow Dash’s swollen lower stomach.

“Me and Derpy have been drinking water all day to fill up our bladders, plus I can pretty much pee like a racepony normally” Rainbow Dash smiled. She looked over in a corner and pointed at a bucket there. “If I didn’t have to hold my bladder for this experiment, I bet I could fill that bucket in ten seconds flat” she bragged.

“Well then, we can see if you’re being truthful or not as soon as Derpy closes the door” Twilight replied with a grin. The grey pegasus next to Dashie nodded, before turning around and shutting the door to Pinkie’s bedroom gently, sliding the bolt to make sure they had a decent amount of privacy while in the room.

Twilight moved over to the cardboard box she had brought up the stairs and looked inside at the apparatus. “I assume Derpy has filled you in on the experiment?” she asked Rainbow Dash, and the two pegasi nodded in response. The Alicorn then began pulling out a long thin tube, a tiny dildo with a open end, a funnel, and a stand for the funnel. “Pinkie, we need you to lie down in the pool for the first part of the experiment” Twilight said.

“Okey Dokey Lokey!” Pinkie Pie replied. She disconnected the pump from the now fully inflated pool, and jumped into it happily, lying down like Twilight had asked her to.

Twilight in the meantime was assembling the apparatus by pushing the tube into the dildo and attaching the funnel to the other end of the tube. She levitated the stand over to the side of the pool using her alicorn magic, and Pinkie watched as the quite large funnel and tube were levitated over towards it and attached to the stand. “Now Pinkie, stay still” Twilight said. She used her magic to levitate the dildo over towards Pinkie’s vulva. Before  Pinkie could say anything, Twilight had jammed it straight into Pinkie’s pretty pink earth pony pussy. Pinkie let out a gasp of surprise as she felt her vaginal walls pushed aside by the dildo, sliding deep inside her further and futher. She gasped as she felt something inside her open and the dildo push into her womb, anchoring the pipe into it.

“Twilight, what are you doing? This feels weird...” Pinkie commented.

“We wanted to see just how much a pony’s womb can contain using the elasticity spell, so we decided to test it on you” Twilight smiled. “We’re going to empty our bladders into the funnel, and it will be pumped straight into your womb until you’re overflowing” she explained.

Before Pinkie could reply, Twilight had moved over to the funnel. She turned around and thrust her rear backwards, so her vulva was hovering over the funnel like it was a urinal. “I get to go first, as i’m your mistress and I always have priority over others” she commented, and let out a sigh of relief.

A strong stream of pee began shooting out of Twilight’s urethra, and poured into the funnel below her. Her waste waters travelled through the pipe and into Pinkie. The pink earth mare suddenly felt a hot liquid beginning to fill her womb up. It was a strange feeling as she felt her uterus filling up with urine, something that would have being completely unnatural and unusual to most ponies. As Twilight’s stream intensified, Rainbow Dash and Derpy could see Pinkie’s stomach was starting to bloat as her womb stretched to hold all the golden liquid pouring into it.

Eventually, after nearly a gallon of piss had exited Twilight, the Alicorn’s bladder was depleted. Not bothering to wipe her slit dry, she turned around and saw Pinkie gazing at her now bloated lower body with a strange smile on her face. “Seems like the experiment is working, and you can hold more than we could have ever expected...” she commented.

“Twilight...” Pinkie breathed. “Its too much pressure on me... please may I pee now?” she asked the purple pony princess.

“You may... but only when Derpy is ready to handle it...” Twilight replied. She turned towards the grey pegasus. “Got the bottle?” she asked her.

“I certainly do!” Derpy replied, with a smile on her face. She wandered over towards Pinkie holding the large bucket Rainbow Dash had pointed to earlier. She pushed it against Pinkie’s vulva just above where the pipe went into her vagina. “Okay Pinkie, when you’re ready!” Derpy declared happily.

Pinkie didn’t reply, but instead let out a sigh of relief. Piss shot out of her urethra and straight into the bucket, filling it up steadily. Her stream intensified and Derpy gazed down in awe as the golden liquid filled the bucket with a quickly increasing liquid level. Pinkie continued pissing away her waste waters even when the bucket was near overrflowing, and by the time her bladder was depleted the bucket was overflowing and the base of the pool was already slightly damp from her hot yellow urine.

“Thats a lot you put out...” Derpy smiled, pulling the bucket away from Pinkie and almost dropping it in surprise by the weight of it. “...and its to go back in, right Twilight?” the young pegasus mare asked.

“Thats right” the pony princess replied. “Pour it all in when you’re ready, Derpy” she commanded.

“Okay!” Derpy Hooves replied, then moved over to the funnel and poured the contents of the bucket gently into it. Pinkie gasped as she felt the several pints of urine she had held inside her flow back into her body. Her womb bloated as her own piss flowed inside and mixed with her mistress Twilight’s waste waters as well. Her stomach swelled to contain all the urine inside it, and once the last drop had flowed out of the bucket, Pinkie was feeling even more full. Yet she knew it wasn’t over yet...

“That... was... awesome!” Rainbow Dash grinned. “However its my go now, and my bladder is at least 20% fuller than Twilight’s” she added with a sly look. The blue pegasus flapped her wings and hovered over to Pinkie in the pool. She jammed her blue rear against the funnel so her vulva was against it, and breathed a sigh of relief.

Pinkie let out a gasp of surprise as Rainbow Dash started peeing into the funnel with even more force than Twilight. The blue pegasus breathed a sigh of relief as she pissed away her discomfort down the funnel and tubes and into Pinkie’s Womb. Pinkie felt her uterus bloat even more as the contents of it mixed with Rainbow Dash’s waste waters that was surging in. Dashie certainly could piss like a racepony, and over a gallon of her golden rain sprayed out of the pegasus until her bladder was finally depleted. “Told you I could outdo you Twilight” the blue pegasus smiled as she flapped her wings and moved away from the apparatus.

“Me next!” came the bright voice of Derpy Hooves. Like Rainbow Dash she hovered over towards the funnel. However rather than land, she flipped upside down and kept hovering in the air. “My favourite position” she said, before she sighed a breath of relief and began pissing. Pinkie felt her womb filling up even more as the grey pegasus’ hot yellow urine sprayed downwards in and arc into the funnel, passing through the tube into the pink pony’s body. At this point, Pinkie’s uterus was swollen with over three gallons of piss and her stomach was bloated beyond what anyone had ever seen before. Suddenly though, Derpy’s stream ended sooner that the other two ponies’ streams had done, and she hovered away from the funnel. “Done!” she declared as she landed next to Rainbow Dash.

At this point Pinkie was rolling on the bottom of the pool groaning, her hooves carressing her swollen lower abdomen. Rainbow Dash gazed at her. “Damn, she almost looks like she’s pregnant with all that urine inside her” she commented.

“She’s probably carrying a piss baby then” Twilight said, and she and the two pegasi chuckled. “Well Pinkie, we’re all out of pee, so its time for you to just let it go” she added. Before Pinkie could respond, the purple alicorn had yanked the tube away from Pinkie, and it pulled out of her vagina inch by inch with the head of the dildo coming free with a light pop. As Twilight removed the tube, Pinkie let out first a loud groan before letting loose everything her 

A torrent of piss forced itself out of Pinkie’s stretched vagina, pouring into the pool. Pinkie breathed a long sigh of relief as she felt her womb slowly begin to empty itself. A mixture of the four ponies’ urine came out of her, with her swollen belly slowly beginning to deflate. The alicorn and the two pegasi watched as the pink earth pony appeared to piss away the waste water inside her without a single shred of dignity right in front of her friends.

Despite the discomfort of holding so much piss inside her, the feeling of spraying it all out felt amazing to Pinkie. She thought about how much she liked it as she felt an orgasm build inside her. Pinkie found that pissing was sexually pleasurable to her, and more than a few times she had orgasmed from pissing out a large amount. She let out a scream of pleasure as the first gallon of piss left her, the stream faltering as she had an epic orgasm from emptying the liquid from her womb.

Her stream soon recovered, and she continued letting the stream of urine out with even more ferocity. Another gallon filled the pool to overflowing, and as she screamed in her second piss orgasm, the amount of urine in the pool overflowed onto the floor. Twilight, Dashie and Derpy looked down to see their hooves getting wet as the golden liquid flowed across the floor. Instead of getting upset at their hooves getting messy, they smiled at the feeling of the warm liquid around them.

Still more piss flowed out of Pinkie’s vagina, and after a third gallon came out she orgasmed again as the room was filled with piss up to Twilight’s knees. Pinkie writhed around in pleasure as she let out moan after moan, and finally the last half gallon of pee sprayed out of her. She laid back in happiness and afterglow as her friends gazed at her in the middle of the piss-flooded room.

“Looks like the experiment was a success, and Pinkie is enjoying it too” Twilight smiled.

“No doubt she couldn’t hold it back any more” Rainbow Dash commented.

Twilight nodded. She gazed at Pinkie lying down then turned to the others. “Think she’s ready for the next experiment I have planned?” she asked the two pegasi.

“You mean the one with your...” Derpy started, and Twilight nodded in response, cutting her off. “Well, if her body can stretch to accommodate all our pee, i’m sure it can stretch to accommodate that... thing of yours” she commented.

“Okay i’m going to do it then” Twilight smiled. She stepped over the wall of the pool and felt its warm contents rise up to the tops of her legs. She waded through the mixture of their urine and towards Pinkie, who was sat up against the wall of the pool. “Firstly, a buoyancy spell may be helpful” she said, and her horn glowed. Pinkie suddenly felt herself get lighter and within seconds she was floating on top of the golden liquid. “Now, its time to test out my next experiment” Twilight smiled. She lowered her head, took in a deep breath, and thrusted herself forwards.

Pinkie let out a gasp of surprise as she felt her vagina penetrated suddenly. The object that slid into her was a smooth cone that was very warm and textured. She looked down and saw to her surprise that Twilight had shoved the first few inches of her alicorn horn straight into Pinkie Pie’s vagina. She barely had time to say anything before Twilight had began pushing her head back and forth slightly, her horn sliding in and out of Pinkie as if it was a stallion’s cock.

As she horn-fucked Pinkie, Twilight felt strange sensations running through her body. She had decided to try this with Pinkie because she had found that her alicorn horn was very sensitive to been rubbed. It turned her on maybe even more than having her pretty pink pony princess pussy stimulated. She had decided to see if using her horn like a penis would bring more pleasure to her than having her vagina penetrated. And from her early observations, it seemed to be working.

Pinkie on the other hand was feeling much stranger sensations within her. Her pussy stretched in odd ways to accommodate Twilight’s swirly horn with a pointed tip. She was enjoying the feeling of it sliding in and out of her, even though the very concept of being horn-fucked seemed very strange to her. However she was enjoying the feeling so much, thoughts began to flow into her head about her attraction towards Twilight. This was exactly what she would have wanted from her potential life partner...

In the meantime, Rainbow Dash had noticed that Twilight Sparkle’s vagina was starting to drip some juice. It had been a while since Rainbow Dash had spent some time having sexual fun with Twilight, and was eager to taste her vulva again. Without saying anything, she moved towards Twilight and leaned over the wall of the pool so her face was against the Alicorn’s rear. She kissed her friend’s delicate pussy, before beginning to lick away at it eagerly.

Twilight moaned as she felt Dashie’s tongue against her pussy. Rather than tell her to stop though, it turned her on enough to start thrusting in and out of Pinkie even faster, inch after inch of her alicorn horn sliding into Pinkie’s vagina. She began moaning louder and louder as Dashie began pushing her tongue inside the purple princess’ vagina, eager to taste her juices.

The faster Dashie licked, the faster Twilight thrusted her horn into Pinkie, and the more the pink earth pony moaned in happiness. Soon it was too much, and as Twilight thrusted her horn all the way into her friend’s vagina, Pinkie reached her limit and her orgasm exploded inside her. Waves of pleasure flowed through her body as her vagina poured juices all over Twilight’s horn and leaked out of her stretched hole, dripping onto Twilight’s forehead.

Twilight felt Pinkie’s warm vagina constricting around her horn and it was enough to make her orgasm too. Waves of pleasure flowed through her and her juices splurted out of her vagina, all into Rainbow Dash’s eager mouth. It was a much greater orgasm than any she had ever had before, and she had Pinkie Pie to thank for it... and not just for letting her shove her horn inside...

Once their orgasms had faded, both Pinkie and Twilight stayed in their positions, still connected to each other. After several tense moments, Rainbow Dash was the first to speak after she had backed away and swallowed all of the vaginal juices Twilight had leaked into her mouth. “That was so awesome!” she exclaimed happily. “What do you think, Derpy?” she asked.

“Certainly was, the most fun i’ve ever had with Watersports” the little grey pegasus giggled. “Did you enjoy your first experience with pee play?” she asked the blue pegasus.

“Absolutely, and i’d like to try more” Dashie replied. “Say Derpy, how about we go downstairs, fill up on lemonade, then scissor each other?” she asked. “It would be fun to piss on each other while we’re scissoring, and you deserve some attention today for inviting me” she added.

“I’m definitely up for that” Derpy replied with a smile. She and Rainbow Dash opened the door and watched as the piss flooding the room surged down the stairs into the lounge. “Looks like we’re gonna get very wet anyway” Derpy commented.

“I’m not complaining” Rainbow Dash chuckled. The two pegasi put right hooves together in agreement before they descended the stairs to continue the fun.

After a few minutes, Twilight recovered enough to withdraw her horn from Pinkie’s vagina. It came free, covered in Pinkie’s vaginal juices. Pinkie was still feeling the afterglow, and Twilight smiled down at her. “You did well, slave” she said to her.

“So did you... Mistress...” Pinkie replied. “Your horn felt... so good...” she added.

“Thats good, because now we’ve seen that we can both get sexual pleasure from horn-fucking, we can try expanding on it next time” she said. “I imagine it will be quite an experiment... if my slave can handle it” she added. “It might hurt a little, like today most likely did...” she added.

“Mistress, you can do it to me any time you want” Pinkie replied. “In fact, if I had my way, you’d do it right now” she added.

Twilight was a bit surprised by Pinkie’s response. “Are you sure about that Pinkie?” she asked. “Didn’t any part of what we did together this afternoon hurt?” she asked.

“No, I loved every moment of it” Pinkie giggled. “And I don’t just love the things you do to me Twilight... I love you” Pinkie confessed.

“You... love me?” Twilight asked, a little taken aback.

“More than anything Twilight” Pinkie says. “And I... I want to be not just your girlfriend. I want to be your slave forever. Let you use me for sex and peeing all you want, because I love what you do to me and I love making you happy Twilight” she elaborated.

Twilight was little taken aback at Pinkie’s admission, but smiled happily as she heard it. The closeness she felt to Pinkie was mutual, and the thought of having the pink earth pony as her girlfriend and slave at the same time was appealing to her. “Of course i’ll let you be my slave, and maybe my girlfriend” Twilight smiled. “So long you know what I have planned for you” she added.

“What do you have planned?” Pinkie asked.

“Oh, making sure you’re woken up by your bed urinated on by one of our friends every morning, wearing piss-soaked clothes every day, drinking only mine and your own urine, letting me hornfuck you and fist your cunt many times a day, and...” she started, then grinned at her. “...let me impregnate you with my foals, once I dig out my spell book that will allow me to” she grinned.

Pinkie was taken aback by her suggestions. All the things she had loved Twilight doing to her over the past weeks were now going to happen every day to her. “I can’t wait for all of those things... can we start tomorrow, Mistress Twilight?” she asked.

“Of course we can, I love you Pinkie” Twilight smiled. She jumped back into the pool until she was immersed completely just as Pinkie was. She swam towards Pinkie and gave her a kiss on the muzzle before hugging her passionately.

Both in the bedroom and downstairs, the couples were hugging each other passionately. Their love for each over and their love for the kinks they enjoyed doing together had created a bond that was unbreakable between them. The two couples laid there happily in their respective rooms, knowing everything would be wonderful for them from that day onwards.

- The End -
