“Twilight! I’m… I’m trying to focus!” Rainbow objected, trying her best to concentrate on filling out some Wonderbolt papers instead of her marefriend undressing right next to her.

Twilight smirked as she finished unbuttoning her shirt, throwing it off which would have given Rainbow an almost perfect view if it wasn’t for the silk-black bra.

“Really? You sure that’s what you should focus on here?” Twilight’s smirk grew as she shook her impressive rack towards Rainbow.

“Y-Yes! I need to get this done!” Rainbow nervously said, starting to sweat slightly. She’d never been able to resist Twi, but this was pretty important…

“Oh… Is that any way to treat your master?~” Twilight purred.

Rainbow felt a chill run down her spine, she definitely couldn’t resist Twilight if she kept this up. “Look Twi… We’ve been experimenting all week long, from dragon sex to gryphon sex, and… I can’t lie, it was fucking hot. But, I need to do this work… After I’m don-”

She got cut off by the sound of Twilight’s magic, the telltale feeling of it tingling her coat. Only a moment later she found herself feeling slightly colder as the fresh evening air blew over her fur. Rainbow just blinked and when she opened her eyes, she was completely naked, her nipples standing erect because of the now colder temperature that enveloped them.

“Twilight! Come on, you know that I-” Rainbow stopped as she got cut off again by the sudden sound of magic. Rainbow’s breasts soon were encircled by the tingly warm sensation and expanded all the way to plump E cups. The change caused Rainbow to bite her bottom lip nervously as she felt pleasure shoot throughout her body. Twilight knew Rainbow loved the arousing feeling of transformation magic, whether it’s turning into a dragon or growing a cock, Rainbow almost instantly got turned on by any transformation.

“Okay… Fine. But just a little while, then I can start working on this again…” Rainbow gave in while she put her papers down.

Twilight rolled her eyes, quickly teleporting the rest of her clothes off and enlarging her own breasts to match the pair she gave Dash. “Fine by me!~” Twilight responded.

Rainbow closed her eyes and took a deep breath. Even seeing transformation magic on someone else turned her on so much that she could feel a slight tingling in her loins. “Okay, I’m rea-”

She got cut off yet again by Twilight jumping on her, tackling her down.

Rainbow didn’t even try to fight it, it was just in her nature to be submissive and in Twilight’s to be dominant.

Within seconds Twilight leaned herself down, letting the two mares’ bodies press against each other as Twilight had her hands around Rainbow’s arm, pinning her down. Another smirk from Twilight and she went in, her head slowly leaning forwards until her lips met with her marefriend’s.

Rainbow closed her eyes, letting wave of arousal after arousal hit her. Arousal that was just adding up from the passionate kiss and their plump breasts pushing against each other, leading all the way down to her damp pussy, only made more slick from another soaking wet cavern pressed right against it.

Both of their tongues battled for space while pushing against each other. They both moved in and out of the other’s mouth, trying their best to explore as much as possible. Rainbow soon let her submissive nature take over more, putting up less of a fight for space and letting Twilight’s tongue boss hers around, pinning it down to roam her mouth freely.

The pleasure kept adding and adding for what seemed like forever, eventually pausing for a moment as Twilight forcefully ended the kiss, a big smile across her face. This was a look Rainbow knew all too well. “Twi… Can’t we just stay like this, have some normal sex for once this week?” Rainbow commented. As much as she loved transformations, they had tried everything already.

“Hmm. You know most people consider normal sex having a cock as well as a cunt, right?” Twilight said as her smile grew, something Rainbow somehow didn’t notice.

“You know what I mean, we could ju-” Rainbow said as she got cut off again by the sound of Twilight’s magic, soon after she felt a slab of something hit her right above her pliable cunt. It didn’t take a genius to realize that sensation came from a throbbing horsecock, one that was attached to Twilight herself.

Twilight just let out a small giggle as she prodded her new horsecock against Rainbow’s dripping wet pussy. Rainbow froze in anticipation, her eyes focused on Twilight’s veiny shaft just waiting there, ready to penetrate and dominate her athletic frame. Twilight was still pinning Rainbow down, now looming above Rainbow slightly as her breasts hung down towards Rainbow’s. They both stayed like that for a while, sweat starting to form as each of them waited for the other to do something.

Twilight gave in and rolled her eyes slightly, “Really, Rainbow? You’re not going to beg for me to fill you up?~” She finished as she thrust out slightly and prodded Rainbow’s pussy again.

Rainbow didn’t think about it for one second as she was mesmerized by the throbbing piece of horsecock that was dangling between her legs parting her labia slightly. “Oh, please! Please Twilight!~”

“That’s it?~” Twilight teased, prodding her cunt again, eliciting a whimper from the needy pegasus mare.

“Pleassssssssseeeeee Twilight. You know how much I love being your sex doll, just fill me up alr-” She stopped herself, looking at the mischievous glint that was forming in Twilight’s eyes and instantly regretting her own choice of words.

“Sex doll, huh?~” She teased, lighting up her horn quickly and focusing the magic at Rainbow.

“No! Twilight, I know we lo-” Her mouth froze in place, making an almost perfect circle. Her skin changed color slightly as it slowly spread around her body, forcing her into one stiff position. Before soon her body was completely changed, light glistened and shined off her body a lot more, and she couldn’t move a muscle. She couldn’t talk, only think, she was nothing but a rubber sex doll now. Twilight’s rubber sex doll.

‘Fuck… I hate and love her so much right now’ Rainbow thought, hating Twi for truly making her helpless...but at the same time she couldn't deny that being unable to move, unable to stop her friend, made it all the better for the prismatic mare. She couldn’t decide which action to take, love or anger. She wanted to be angry at Twilight for immobilizing her without her consent, but... just couldn’t help herself as the love for her new state wouldn’t stop growing.

Twilight had the biggest smile she’d ever saw on her face. “Why haven’t we tried this before!” Twilight released a high-pitched squee filled with passion, letting her hands wander over the smooth texture of Rainbow's new and shiny rubber body.

“Mmmm, I could just drop you in the middle of the street and leave you there. Let some stallion come through and take you home; use you like the worthless sex doll you are.” Twilight said with a slightly cruel yet mostly humorous laugh at the end.

Hearing this should have made Rainbow scared or worried, but it only made her horny. She could feel heat growing and growing in her rubber loins, the thought of being used, the stallion not even considering she was alive, just using her like a doll… it just made the burning in her crotch intensify and she wished nothing more than that she could move to rub her legs together, to let her hands wander down to her dripping flower. ‘Fuck… Why haven’t we done this before?’ she questioned herself.

“Mmm, My Little, Widdle Dashie Washie…” Twilight said as she set focus on her throbbing cock some more, prodding it against Dash’s rubber hole. She quickly pushed one inch in, causing an almost instant moan to escape her mouth. She was amazed just by how the rubber stretched around her cock, hugging it in a snug container.

‘Ohhhhh!,’ Rainbow moaned out in her head, the feeling of herself fitting perfectly with Twilight’s huge cock was just orgasmic. She may not have been able to physically cum, but she still felt every bit of pleasure.’More. MORE!,’ she moaned out loudly in her head.

Twilight continued taking a moment to bask in the feeling. After she was done, her smirk returned as she took no time forcefully shoving the rest of her length in, moaning out even more from the smooth, rubbery texture she felt moving and stretching around her shaft.

‘Ohhhhhhh!~ Fuck! More!~ I need more, please!~’ Rainbow moaned out in her head, loving this feeling of the massive alicorn cock in her. A cock that seemingly stretched her rubber walls and added more and more to the burning in her loins, burning that needed to be dealt with immediately. This feeling was way better than any of the other times she had been transformed with transformation magic.

Twilight looked at Rainbow’s face, realizing why her mouth stopped in that shape, “Oh… We’re going to have a lot of fun with that~,” She said, finding she didn’t need to pin Rainbow down any more. She moved her hands and, without pulling her cock outside of the rubber cavern, she stood up. After picking Rainbow up, she moved her over to a glass table, smirking as it had the perfect height for Twilight to stand tall and thrust hard into her new doll.

’What’s taking so long!? Fuck me already!’ Rainbow cried out in her thoughts, craving to be fucked and utterly dominated by her nerdy marefriend.

Twilight took a better stance, then thrust her entire length out and shoved it entirely back in, smirking more as she got an idea and quickly and forcefully slapped Rainbow’s rubber ass, her hand bouncing back pretty quickly.

Rainbow entire being was filled with pleasure, feeling everything from the ecstasy to the stinging pain, loving everything, loving every thrust of this large steaming hot horsecock, loving every stinging slap on her smooth ass, loving being completely and utterly helpless, just loving every single thing happening.

“Ohhh, I can’t harm you like this. Meaning, I can-” She suddenly slapped Rainbow’s rubber ass again, harder than the first time. “Do that as many times a I want~,” she added in a teasing tone.

If they could, Rainbow’s eyes would've rolled to the back of her head just by that demonstration of dominance.

“Okay, enough with playing games. Does my Dashie Washie want to be fucked hard?” Twilight said while grabbing Rainbow’s soft, smooth ass, trying to get the best position possible.

‘Yes! YES! Rut me hard!~’ Rainbow screamed out in her head, knowing Twilight couldn’t hear her, but being unable to stop herself.

Twilight didn’t take long to slap Rainbow’s rubber ass again, right before thrusting her length out. Suddenly slamming it back in. She did it again, thrusting out before thrusting herself back in. Again. And again. She soon picked up a nice rhythm from her balls slapping rubber to her tits flying around in the air as she forcefully fucked Rainbow.

‘YES!~ OH CELESTIA YES!~’ Rainbow thought as she was filled with so much pleasure it felt like she was having orgasm after orgasm, though with nowhere for the pleasure to go and leave her, it just continued growing and growing.

Twilight continued her rhythm, smacking the rubber ass in front of her every ten-ish thrusts. She could feel her balls churning, wanting to release her load into her new sex toy. Twilight held back though, having a smug idea in her head.

“Hey Rainbow… Let's say I ‘fix’ the futa spell?” She suggested, still thrusting hard into Rainbow.

’I don’t care! Just fuck me! Ohhhh!~’ Rainbow thought, letting the pleasure fill her up almost as much as she wanted Twilight’s cum to fill her.

“And make the cum extra fertile?” Twilight finished her statement with a hard thrust, teasing Rainbow along as she lit her horn up.

’Yesssss!’ Rainbow thought, not even focusing on Twilight not being able to hear her. Her insides burning with sensations, she felt Twi’s thick cock throbbing inside her, felt every rough thrust, she felt her walls being stretched by the massive cock penetrating it, and she was full of precum that was already dripping down to the blankets beneath them.

Twilight didn’t even say anything as she cast the spell, just going straight to finally releasing a huge load of thick ropes of cum that quickly filled up the rubber container, stretching it slightly. All while moaning out a cry of ecstasy.

Rainbow was lost in pure ecstasy from the feeling of warm spunk splashing against her inner walls, not forming any thoughts besides a constant internal moan.

“Hmm.” Twilight thought, she couldn’t really ask Rainbow for her opinion. So, why should she not do that again? Twilight quickly picked up the light doll, looking for a good place to put it. After thinking and examining her surroundings, Twilight smirked again and just went up to a wall. She quickly pinned her against it, finally having a use for the position Dash’s arms were stuck in from being pinned down originally.

Dash finally cleared her head enough to process anything but pleasure, if she needed to breathe she would be panting heavily right now.

Just like that, Twilight started thrusting in and out of the rubber pussy again, pressing it more and more against the wall as she pounds her into it. Things quickly started falling off the wall from the force of all of her hard thrusts, from some paintings falling to books sliding off nearby bookcases.

At this point Rainbow wasn’t moaning out, she was squealing out in pleasure. Her rubber loins burning more and more with each second.

Twilight took great pleasure as more and more things kept falling from the wall, only making Twilight want to increase the force she used.

Twilight was starting to sweat a decent amount, making her entire figure from her breasts to her cock shine more in the light, almost as much as Rainbow. She felt her balls churning again, causing her to smile as she realized she could fill up her personal sex doll even more.

She continued thrusting more and more, giving in surprisingly quickly as she let out a primal cry while letting more ropes of thick, now fertile cum completely flood her already-filled doll. It started to stretch her insides some more, causing a visual bulge to form in her rubber stomach.

Twilight let go of Rainbow, causing her to fall face-first into the floor. Twilight just continued panting, casting a quick spell to help her cock recover faster. She picked up the light-blue doll, turning it back over and smirking at her opened mouth. She assumed Rainbow was tired out, not knowing she’s still squealing with pleasure.

Twilight soon teleported them to the couch, she herself needing to recharge her energy. She still grabbed Rainbow and shoved her rubber face into the erection Twilight still had going.

“Wow Dashie, you’ll let me facefuck you while I get back my full energy. Thanks!~” She almost teasingly purred out as she brought the ‘O’ shaped mouth towards the tip of her cock. “How thoughtful of you!” She added on, right before shoving the head down on her entire cock, letting the rubber muzzle press against the base.

“Not like you need oxygen right now.~” She quickly said, not going gentle as she forcefully starts facefucking the light-blue sex doll. The rubber throat feeling so warm and tight against her member, making her smirk as she noticed how it also stretched and bulged out of Rainbow’s throat.

Rainbow slightly panicked, but relaxed as she didn’t feel anything. Well, anything besides more and more pleasure. Rainbow was loving every single second of this, being a helpless doll, controlled by a strong alicorn cock. It made her somehow hornier just thinking about it. If she could move her tongue right now, Twilight’s cock would have been licked clean a million times already!

’Screw it’ Twilight thought, not wanting to waste any time by getting more energy. She quickly just cast another spell, this one focused on the cock now stuffed in Rainbow’s tight, rubber throat.

Twilight threw her head back as she let out another moan, instantly feeling her magic make her way to her balls. Before soon, Twilight’s balls were churning with a new batch of baby batter.

’Oh! Fuck your doll! Fill up your slutty sex toy!~’ Rainbow was moaning out. She loved every last second of feeling Twilight’s cock stretch and bulge its way out of her rubber throat.

Twilight could have just released another load, but loved this opportunity to stretch out Rainbow’s throat without damaging her in any way. She then opened her eyes, having a mischievous smile on her face.

“Oh, I promised you a good facefucking.” Twilight quickly forced her cock out of Rainbow’s throat only to shove it back in again. "So, I'm going to fuck your cute little face so hard, your throat will be sore for weeks!~" She said with another thrust into Rainbow's rubber throat. "Does my Dashie Washie have any objections?" She looked at Dash's frozen eyes teasingly as she pulled out of her throat. After a few seconds of silence Twilight smirked, "That's what I thought," she finished the sentence with a hard and forceful plunge into Rainbow's throat, this time immediately thrusting back out and back in.

’Ohhhhhh’ Rainbow let a cry of pleasure run on, loving every feeling of her throat expanding and stretching to fit Twilight’s cock, only to contract and return to normal right after from how fast Twilight was thrusting into her.

Twilight knew she could release her load any second, but wanted this to last a bit longer. Each time Twilight felt Rainbow’s soft, rubber muzzle on the base of her cock, she didn’t stop there. She forced it down as much as possible, squishing Rainbow’s muzzle slightly before forcefully moving it back until her cock was not in it. She was going so fast, Rainbow was forced to take the alicorn cock four times in one second.

Twilight continued facefucking Rainbow for a few minutes straight, picking up her speed to having Rainbow take her cock seven times a second. But after that few minutes, Twilight could barely hold herself back. Last second, Twilight stopped using her hands to move the doll and started using her magic, getting it to go back and forth on her entire length so fast, Rainbow took Twilight’s cock eleven times a second. She was thrusting her hips along while using magic the fastest she ever had, feeling her next orgasm approach quickly.

Rainbow couldn’t even think at all, even though she couldn’t taste the cock, she could feel every single thrust happening, no matter how many there were. It was happening so fast, that Rainbow couldn’t even moan out in her head, as her brain was numbed by the pure erotic pleasure.

Before she could do anything else, a sudden moan from Twilight caused her to get all excited. ‘Yes! More! Fill me up more!’ She thought after finally regaining her ability to think again. Right after she finished that thought, she felt Twilight hilt herself completely inside the smooth throat, even shoving her chock-full balls inside.

Just like that, Twilight released as she quickly lit her horn up. Rope after rope of hot, steaming baby batter started filling Rainbow’s rubber insides. The cock quickly got covered with purple magic as it continued to coat Rainbow’s throat. Seconds passed, and her magic-infused cock continued to pump load after load into the rubber cumdumpster. It felt like heaven for Rainbow, adding on to her already high amount of pleasure that she couldn’t release. Finally, after what seemed like forever, and to Rainbow’s surprise, the magic quickly dissipated from the cock, and as Twilight let out a loud pant, her phallus seemingly stopped dripping its amazing substance.

Twilight quickly closed her eyes and leaned back against the couch, a huge smirk spreading on her face. “How- How about one last go…” She said seemingly to herself.

“One last go, no magic, just some rough sex with my wittle sex doll!~” Right after that, Twilight stood up, her cock pointing straight up into the sky. She wasted no time and threw her rubber sex doll to the ground, shoving its face into the hard, crystal floor, so Rainbow couldn’t see anything.

‘Hey! W-What are yo-uuuuuuu… doing?’ Rainbow moaned out in her head, knowing Twilight couldn’t answer, but mostly asking herself. Before she could fully process everything, she felt Twilight’s arms going down to pin her like that again, Twilight seemingly mounting on-top of her. Before she could question this, she lost her thought as a warm slab of something started pressing against her tight asshole.

‘Wait.. T-Twi! You know I haaaate-’ Rainbow tried to scream out, only to get cut off by Twilight speaking over her.

“Mmmm, No objections?” Twilight finished, letting out a mischievous giggle.

‘She, she’s r-really...Aahhh...doing it!~’ thought Rainbow as she could feel the pressure of Twilight’s hot cockflesh on her backdoor increase.

Even through all the haze the lust had brought her, Rainbow suddenly felt nervous. She never was one for anal and Twilight knew that. No matter how often Twilight begged to sodomize her tight little pucker, Rainbow had vehemently refused, and that Twilight was now claiming her ass forcefully like that…

Actually it made her feel a little tinge of excitement.

Rainbow could suddenly feel her tight sphincter give way as Twilight’s well-lubricated shaft slowly slipped through her ring. An internal gasp escaped the prismatic mare as her ass was suddenly stretched open and a rather alien feeling of fullness made its way through her smooth bowels.

No protest came out of her mouth, as it was frozen; all that escaped her at that moment were internal strained pants as this new sensation worked itself further inside her ass, as more and more of Twilight’s cock slipped inside of her.

Twilight moaned loudly as the rubber texture of Rainbow’s anal opening squeezed around her shaft while she slipped further inside her.

Soon Twilight’s hips smacked against Rainbow’s hard. The force, as well as the rubbery texture let Twilight’s hips automatically bounce back, taking her by surprise, before a lewd grin spread across her face.

‘This’ll be better than I expected!~’ she thought, as she started to deliberately ram her throbbing hard phallus hard into her rainbow-maned doll, using her momentum to get thrown back as soon as her whole shaft was buried inside her little pucker. She then would thrust inside her again, the bouncing giving her a nice rhythm to fuck this mare before her.

This was made even easier through the rubbery texture which combined with the lubrication made it easy for Twilight to slip her large cock out and inside of her.

Rainbow could only groan as her ass was split open again and again by her ferocious marefriend. Despite all her qualms she had about this form of sex, she slowly started to feel some sort of pleasure with every violent thrust her marefriend gave her plot.

‘By C-Celestia! I-I’m starting...to enjoy it!’’ Rainbow thought as her plot was assaulted by her marefriend, never before had she enjoyed any of the few attempts she allowed Twilight anal. She usually forced her to stop right away, but this time… This time was extremely pleasurable.

Each piercing thrust, each time she felt the hot flesh dive in only seemed to drive that point more and more home for her. It wasn’t painful in the slightest for her, as the lubrication made the movement rather fluent. The only thing Rainbow could feel was the fullness, a fullness which she slowly associated with pleasure. And soon she couldn’t help but crave for more.

As if hearing her plea Twilight’s assault sped up again, the rhythm of her smacks getting more sporadic with each wanton thrust inside her marefriend, who now internally voiced her approval.

‘P-Please! G-Give me...more Tw-Twilight! P-Pound my...Ahhhh, plot!’

Said alicorn couldn’t help but smirk as she was ravaging her marefriend sex doll, as she felt a mischievous urge to degrade her Dashie further. With that she leaned over Rainbow to whisper in her ear.

“What’s that? Are you getting turned on? Didn’t you always say you hate anal?”

Twilight, as if mocking her, waited for an answer, which the pegasus mare of course couldn’t provide in her state. She then held an ear towards her, pretending to hear her, all while still pounding her sensitive plot.

“Huh? What did you say? You want to be my little anal slut? Oh my little Dashie Washie! I never knew you were such a naughty mare!”

She then grabbed with both her hands to squeeze her rubber plot teasingly.

‘OH! YEEESSSSSSSSSSSSSS! PLEASE DON’T STOP! LET ME BE YOUR LITTLE ANAL SLUT!’

A wish, even though Twilight couldn’t hear it, all too happily obliged. She pounded harder and harder into her little sex doll, using her like she was nothing more than a tool for her pleasure, which Rainbow at this moment was.

Her rubber ass rippled violently with each slap of their hips as her balls started to contract, ready to fire her load in the rubbery hole.

“Agh! N-Not yet!” Twilight stated as she forced her balls to hold onto her cum and keep it stored, while pounding her pegasus toy relentlessly. She could feel her balls give a sting of protest, but Twilight held onto her resolve in storing her spunk..

‘I will hold it b-back, and then f-flood my little...Aahhhhhh...doll with a-all...of m-my cum!’ she thought while pleasure continued to wear down at her. Rainbow’s tight ass just kept squeezing her, trying to milk her of her cum.

But Twilight stayed strong. She put her hips into it to fuck her marefriend senseless and fill her to the brim. This was her goal, a goal she intended to reach.

With her resolve mustered she continued to bang Rainbow like there was no tomorrow. The rubber doll gave no sound that she was either enjoying it or not, but Twilight knew that Rainbow was probably going mad from all the stimulation she was giving her. And even if she didn’t, Twilight didn’t care. Right here, right now, this was her doll! And she was going to use her just every way she liked!

It took her a few more minutes until she finally decided that it was time to fill her little rubber sex doll up.

‘Okay, this should be enough. Now take it all my little Dashie Washie!’ Twilight roared in her thoughts, before she rammed herself completely inside of her one last time, burying every inch of her pulsing member inside Rainbow’s rubbery insides. Her cockhead flared before her shaft violently twitched and a stream of steaming hot alicorn spunk flooded Rainbow’s thoroughly pounded plot.

Rainbow herself could only revel in the sensation of having her ass filled so thoroughly. She could feel volley after volley of Twilight’s cum painting her insides as her cock was flexing with each spurt.

‘I-Is she still c-cumming?’ Rainbow thought in a shaky voice as she continued to moan out in her thoughts.

She could feel her walls extend slightly under the pressure of the cum that Twilight continued to cram inside of her. A pressure which only increased as Twilight continued to shoot her sperm into her rubbery depths.

Something that would continue on for another minute until Twilight’s balls slowly stopped their churning.

As Twilight’s cock then finally ceased its fire, she slowly pulled it out. Rainbow’s tight rubber pucker quickly snapped shut after Twilight had completed her action, only a quick spurt of cum following her cock while the rest was contained in Rainbow’s pucker.

It took a few minutes for Rainbow to fully process everything, but when she did she was begging for more.

’P-Please! Fuuuuck me more! Use th-this useless doll of yoursss!’ Rainbow moaned out more and more while still being forced to stare at the vibrant crystal flooring.

“Well… I’m done with this worthless doll,” Her smirk grew in-between the pause, “Better send it back.”

’Whatever! Just- Ahhhh~- Use me!~’ Rainbow moaned in response, only to finally be turned around by Twilight, able to see her and her amazing cock again.

Twilight grinned more, using magic to hover the sex doll, teleporting a box full of packing peanuts right around it. “Should I send you away? I mean, you are a worthless sex doll, I have no use for you.”

’YES! I’M JUST YOUR USELESS SEX TOY!~’ Rainbow moaned out in her head, almost unable to cope with all the pleasure built up in her.

“Seems like a good idea. After all, you are my property.” Twilight loudly says as she closes the box, letting it float there for a few seconds.

’YES! I’M YOURS TO THROW AWAY!~’ Rainbow moaned more, not caring about anything but all the pleasure Twilight gave her, needing to release it, willing to do anything to have that happen.

Twilight decided she had teased the poor mare enough and teleported the box away, while setting Rainbow on the couch, her horn quickly charging up to turn them both back to their normal selves.

It didn’t take long for the rubbery texture to give way again to Rainbow’s soft fur as it spread back all over her body. The first thing Rainbow noticed afterwards was that she could move her mouth again as it relaxed from its force ‘O’ shape. Her throat was hereby now feeling very cramped and slightly sore.

Finally, all the pleasure built up had somewhere to go and just like that, Rainbow’s body released a spray of her juices all over the couch, coating it in liquid as she moaned out the entire time. Her body was wracked violently, spasming out of control as gush after gush was erupting from her quivering snatch like it was a volcano. Rainbow quickly grabbed on to the couch, squeezing it tightly to somehow keep her body stable as to not be overwhelmed, but it was all in vain, as her body simply couldn’t process the immense pleasure that was coursing through it.

Twilight just sat there and watched, thinking ’Huh, Guess she really liked it a lot more than I thought she would!’ Deciding to give Rainbow the time she needed to adjust back to her normal self, which might take a bit considering all the climaxes and pleasure she would have felt separately came crushing down on her in one single moment, effectively frying her brain with the overwhelming pleasure it provided

After it was seemingly over, another spurt of her juices quickly followed, followed by another one and another one. It took a while, but Rainbow had finally finished letting go of all the pleasure and juices that were built up inside of her, her moaning finally stopped, and her grip on the couch slowly released itself, as she was now lying limply in the soaked cushions of her own ejaculate.

With the smell of pure musk filling the room even more, she grew a huge smile on her face. She was taking in everything that just happened, slowly having her eyes close in on her. She loved that more than anything else in her life and she definitely needed to thank Twilight for this wonderful and erotic experience she gave her.

“Twilight… I love being your fuck-toy,” Rainbow said while panting out next to her important papers as she almost fully went to sleep.

Twilight smirked again, her cock finally gone as she gets multiple new ideas “Fuck-Toy?”

Rainbow opened her eyes slightly, looking at Twilight’s devilish glint in her eyes and instantly regretting her choice of words. Before she could object, however, she quickly passed out on the couch covered with her juices.

Twilight decided to leave her be, after all she now had a lot of ideas to plan out for tomorrow. Not to mention also having to buy a new couch.

Author's Note

Well this was fun to write.
First commission, and first story with a good ending.

I don't really know how the Sex Doll Transformation will make people react, but it was part of the commission. Not to mention I was writing a story with a Sex Doll Transformation before getting this commission, so this was some nice practice.
