Rainbow Dash was returning from Cloudsdale with her bag in tow. She had just gotten back from a big tour with the Wonderbolts, and she was working hard, so hard that she was finally looking forward to being with her friends. However, as she flew back to her house, she saw a letter in her mailbox, among other things, with some very familiar sparkles on it. Taking her mail inside, she started with the letter from Twilight, eyes scanning the sparkling parchment before groaning at the news.

“Are you kidding me, guys?” She said to herself, tossing the note on the bed. “I just got here!” Sighing, she decided to look through the rest of the mail. There were some residual payments for her previous tours, some fan mail, some coupons, and strangest of all, a magazine with a very done-up mare in a feminine dress and makeup. Attached to it was a card of some sort, reading:

Hello owner of the following residence,

We at the Cosmarepolitan noticed that you had not received an issue before and wanted to offer you a free issue along with an easy-to-fill-out form to send to us! Simply write your name and check the box on the card and give it to your local post mare! Your address and our office are already on the card! We hope you enjoy your free issue of Cosmarepolitan!

Rainbow rolled her eyes. It was a free sample of a dumb magazine for mares like Rarity, the very feminine ones who obsess over makeup and hair and dresses and their bodies. A tough, badass mare like her didn’t need any of that. She tossed the magazine aside, lying back on her bed and looking up at the fan mail. Smiling as she read through them, each one giving her pride in her accomplishments and that she was inspiring more and more pegasi to get out there and fly hard. Then, she read through one in particular.

Rainbow Dash,

Hope things are going well for ya, brah! I just wanted to say that I think you’re the coolest, baddest chick around! You kick all sorts of major butt out there! I mean, sure, you kinda look like a stallion, but it’s not a big deal when you’re the fastest of the Wonderbolts! Anyways, here’s some bits, I hope you make good use of them!

Forever hanging loose,

Cloud Surfer

She didn’t know why, but for some reason, this letter bugged her. She wasn’t one to be uncomfortable with her lack of femininity, but she didn’t think that she looked like a full-on stallion! She angrily crumpled up the letter and threw it at the wall, letting the bits packed away to stay on the bed. Standing up, she paced back and forth with her arms crossed.

“Stupid jerk… So what if I don’t have Pinkie’s boobs or Applejack’s butt or Rarity’s… Face! I’m still sexy! In my own way!” She gripped her face. “Aaaagh, why did I say it like that??? I shouldn’t even care! I’m a Wonderbolt, not some kind of fashion model!!” And yet, as she turned to the mirror, she couldn’t help but see what Cloud Surfer was getting at. She did have a very… Well, not manly, but not a feminine form. It was athletic, but with her hairstyle and her frank lack of grace, she could easily be seen as a stallion in the wrong light. The binding sports bra didn’t help either, but it was hardly holding anything back but B-cup breasts. Taking it off and looking at her topless form, she couldn’t help but feel a small sense of envy for her more endowed friends, which at this rate was everyone. Even though Applejack was about her size chest-wise, she made up for it with a decent ass. With a sigh of defeat, she came to the sobering conclusion that she was the ugly friend of their group.

She collapsed onto her bed in defeat, groaning to herself as she felt the deflating sense of her realization hitting her. She really couldn’t alter her genetics to be more girly, that would require some kind of magic, and well, Twilight wasn’t really able to do that. Not to mention the thought of asking her to do that would be humiliating. That was when she slowly gazed upon the discarded magazine. She let out an exasperated sigh. “Am I really going to…?” she muttered to herself before closing her eyes and grabbing the magazine quickly, looking at the cover once more. Like before, it was a well-dressed, very feminine mare in a sparkling dress with a seductive smile. Huffing a bit, she looked through the cover’s articles, wondering if any were worth her time until one caught her attention:

Tame your Inner Tomboy! 5 Surprising Secrets to help you go from Tomboy Trash to Fabulous Fash!

She raised an eyebrow. It was like this magazine was designed to fix a problem that was started by that letter. It almost warranted suspicion and made her check to see if that Cloud Surfer guy’s name was on the magazine. When no such name was around, she reasoned that it was just some kind of coincidence. These things can happen. Shrugging, she flipped through the pages, skipping to the article she wanted and looking through it. The beginning was just some fluff piece about the writer who apparently used to be a tomboy herself, but what really caused Rainbow to double take in shock were the before and after pictures. Before, she looked like a punk, even more butch and manly than even Rainbow. In the after image, she was in a beautiful dress, hair done up nicely and with a complexion that tied everything together. She looked like someone who Rarity would spend time with, or someone she’d meet in Canterlot! “M-Maybe…” She said to herself, reading a bit more. “Maybe this could actually do something for me.” She nodded at the magazine. “J-Just for today. Just to see…” With that, she went to the first step…

~~~

Rainbow Dash looked up at the sign to the salon, hiding behind a hoodie. For some reason, it was always useful in hiding her identity, and that was what she needed in order to complete the first step. She looked back at the magazine and read it quietly. “Step 1… Treat yourself to something feminine, like a shopping spree or a trip to the spa. Show yourself beyond the layer of tomboy activities that you usually do.”

Gulping, she looked through the window, hoping no one she knew was in. Thankfully, it looked like it was a light day, and no queue was up. With bated breath, she zipped in, speedily lowering the curtains around the lobby before dropping the hood.

“Ah, Miss Rainbow Dash,” Lotus spoke in her usual accent. “I am surprised to see you, your usual indulgent hooficure is not for another few days.”

She shook her head. “I-I’m not here for that. Well, not just that…” She shuffled in place nervously, the twin mares looking at her with confusion before she spoke up. “I… I wanna be… More girly and junk. I-I’d like the full-on beauty treatment…”

A mutual gasp escaped the two. “Miss Dash, this is most unlike you,” Aloe said. “Is there any reason you have decided to-”

“L-Look, are you gonna do it or not??” She snapped back, already feeling regret about the decision. However, as she did so, Lotus spotted the magazine in her hand and immediately recognized it. She smiled and approached her. “Ah yes, you are reading Cosmarepolitan, yes? I have read this article too. If you are liking, we can get steps one through three done~”

Dash’s eyes widened, shocked at their reaction. “W-What, are you serious?”

Aloe nodded with her. “Of course! And if you are liking, if you are not liking this, you don’t have to pay a bit!”

She blushed and rubbed the back of her head, about to reconsider before both mares grabbed her arms and pulled her deeper into the spa. Her eyes would shrink down to pinpricks, trying to resist until eventually she found her way into one of the changing rooms and was given a fancy, soft and pink robe. “Just put away all of your things and we can begin step one.” With that, they closed the door behind her, leaving her to change out of her clothes. She slowly stripped herself down, taking her sweatpants and hoodie off followed by her bra and panties. It was then that she spotted herself in the mirror again, seeing her toned physique and gulping as she slowly assumed a few poses that she saw in the magazine. She’d start with her hands on her hips, then a hand on her head and on her hip, then finally, putting both hands over her head, tilting her body ever so slightly, trying to accentuate the natural curves of her body that she lacked. Soon, a part of her head thought. A knock came at the door, snapping her out of her concentration.

“Miss Dash, are you ready?”

“U-Uhh, just a minute!” She called out, grabbing the much fluffier and girlier robe and slipping it on. She stopped for a moment to let the soft fabric cover her body. It was almost like a cloud covering her, making her blush as she hugged her body for a moment before shaking her head and walking out. Lotus met her with a smile and took her hand, guiding her into the next room. “We have closed the shop for a little bit while we perform your full beautification routine. We know you are very nervous and wish to give you total privacy while we bring out your inner beauty. Now, let us begin with the usual.”

They sat her down in a chair, with Lotus grabbing a file and working the nails on her hand while Aloe took her hooves and began to give them a deep massage. This always caused tingles to spread across Rainbow’s body and she bit her lip and smiled a little, as today, the feeling of getting her hooves massaged felt even better. She lied back, looking up at the ceiling as she let out the occasional squeak in pleasure as she closed her eyes. She saw herself on a beach in a two-piece bikini, breasts almost as big as her head as she was tended to by some faceless stallions in loincloths. They fanned her, gave her drinks, and of course, rubbed her hooves. So lost in the fantasy she was that she let out a soft moan, forgetting that she was still in the room. She quickly snapped out of it with red cheeks, looking at the two who smiled at her warmly.

“Do not worry about us, Miss Dash. We are here to help you with finding your true beauty. Simply lie back and enjoy yourself.”

She nodded a bit, closing her eyes again as she smiled to herself. It felt nice to receive this kind of treatment, allowing herself to indulge in things her ego wouldn’t allow her to do before. After a dip in an exfoliating bath and a mud mask, they would then move on to the full body massage, and thankfully Bulk Biceps was not in today.

“Oh, him? He is out of town for week,” They’d clarify as they got the massage oil and slowly applied it across her body. “Visiting family in Cloudsdale I believe.”

She nodded slowly as she lay down on the table, feeling four sets of hands expertly navigate her body better than she knew herself. She felt like her soul was ascending as she had every inch of her. The whole time she was massaged, she once again indulged in a fantasy involving her and an especially handsome stallion on a bed, surrounded by candles and covered in rose petals. She never had these feelings before, but then again, she never indulged in such things before, and it was so good, she didn’t hear Aloe’s mention of her body glitter.

In truth, Dash’s body was sparkling with magic as the two massaged her, and as they did so, their eyes would be glued to her body, the shiny magic residue working its way onto them as well. As this happened, all three of their bodies would slowly undergo a change. The pair would find Rainbow’s athletic physique gradually softened in their hands, every massage weakening the hard muscle until it matched their bodies in muscle mass to soft fat. Inch by inch, they’d soften up her body, and as they did so, it would all pour into two places: Her breasts and her ass. Gradually, they would grow in volume, her ass jiggling more and more at the slightest movement while she shifted in place as her tits went from B to C, jumping to DD and finally stopping just short of F cup.

The twins as well would also go through the same transformation, but way easier than Rainbow, taking mere moments where Rainbow took at least a few minutes. However, when she would open her eyes, the sparkles in her eyes slowly entranced her, and her mind told her that she was always like this. She blinked, confused a little before she looked at the twins and smiled.

“That was really good… What next?”

“Next, I am doing step two, giving you a wonderful application of makeup…” Lotus motioned to herself before motioning to Aloe, her voice now more sultry and accent slightly thicker. “And Aloe will be doing step three, where she will give you beautiful hairstyle to help show your uniqueness. She has one picked out.”

She nodded and completely forgetting her robe, she followed the spa owners to the next area, a salon where they would sit her down and begin their next two processes. Lotus would take out a big makeup kit, easily the size of one of Rarity’s bags, and would go through the foundations to find the right color while Aloe would begin by brushing the still damp hair of Dash, going long and slow with each stroke. She sighed in content and watched herself in the mirror as the former tomboy was actually starting to resemble a mare. And yet, the changes wouldn’t stop. With each stroke of the brush, her hair inched a bit longer, going from her shoulders to her back and then lower and lower. While this happened, the foundation was placed on her face, giving her a softer complexion as she applied it. She paid attention, wanting to learn this for herself in case she wanted to try it at home, but so focused she was, she didn’t notice her own face becoming soft and smooth, with the application of lipstick giving her actually full, plump lips.

The sparkles quickly retconned the changes in her mind, telling her that everything was fine. She was beautiful, and that was what she wanted. She smiled and nodded to herself slightly as Aloe took a curler to her hair and tail, giving them a bouncier look to them. However, as she moved the curler around, it began to glow and sparkle and when she would move the curler down, it would act like it was removing the color off her hair, replacing the rainbow with a pastel, slightly pinkish variety.

Again, no one would notice the difference, and by the end of the whole exchange, Rainbow was admiring herself in the mirror, striking more feminine poses with a happy, if slightly vacant smile. She turned to the twins. “I feel sooo much better!” she exclaimed cheerily, spinning in place and letting out a giggle that was very out of place for her. The twins giggled with her, clapping as she spun and saw the sparkles sprinkle off her and shower them. Their eyes would go vacant as Lotus spoke up.

“Now you, like, have to get new outfit! That’s step 4! And then...” She paused and scratched her head, trying to remember what the last step was. However, Rainbow Dash shrugged and gave the two a tight hug. “I’ll go to Rarity’s! She’s gotta have something! Thank you both soooo much!” She practically skipped her way out, feeling like a whole new mare before going to the changing room naked. And as she left, the two just stared, feeling like something was wrong…

“Wait, did we, like, charge her for treatment?”

“... We charge people to make them sexy?”

~~~

Rainbow’s sunny attitude was soured somewhat when she remembered what she came to the spa in, but she had no other choice than to slip into it for now. No reason to show her new look now, she thought. Not until I look perfect, and that includes a perfect outfit! She headed to Rarity’s boutique, but instead of her usual swift powerwalk, she moved with a saunter and a sway of her hips. This caught the attention of the stallions and even a few mares, none of whom knew who was behind the hood but were so enthralled by her hips and tits, they weren’t too bothered by it, and she was showered in stares and whistles. The feeling of the attention filled Dash with the same kind of pride as when she was performing, except with way less effort! This caused one thought in the back of her head. Why was I so focused on flying…?

When she arrived at the boutique, the place looked empty through the windows. Rainbow tilted her head, deciding to try the door. It opened with no effort. “Weird,” she muttered as she entered the building. Looking around, it was like Rarity just got up and left. This was enough to unnerve Dash a bit, snapping her from her bubbly attitude. “Rarity? You in?” She called out. No response. This is getting pretty spooky… She gulped and looked around, sorting through the dresses to get her mind off of the emptiness. For some reason, the thought of being caught like this was… Bad. Why was it bad? She liked this new look, right?

All those worries went out the window the moment she found what she was looking for: a low-cut, pink dress covered in sequins that shimmered with every little movement. It caught her eye and popped and she needed to try it. To top it off, nearby were a pair of pink heels that looked to be just her hoof size. Snatching the dress and heels, she strutted over to a nearby changing room, throwing her sweatpants and hoodie onto the ground and letting her naked form be exposed. She closed the changing room door behind her, feeling the dress hug her every curve just perfectly, as if the dress was made for her. She never felt happier wearing an outfit like this. Even her gala dress was blown out of the water by this shimmering piece of fashion art.

When she exited, she posed for herself in a vanity mirror and smiled wide with a giggle. She loved this new look. Softer body, softer face, perfect makeup, cuter mane and tail, and now a sexy dress! She was just one step away from being perfect! All she had to do was…

She blinked, her smile slowly fading to a look of confusion as she scratched her head. Now she had to… What was step five? Did the Spa Sisters even tell her? She huffed and pouted, stomping her foot lightly and tightening her grip into fists. “Ohhh, those, like, total airheads!” she exclaimed, stomping out of the boutique. She couldn’t believe it! She was so close to finding her true, beautiful, fashionable self, and she tripped on the last hurdle! She didn’t even have her magazine on her…

As she walked through Ponyville, sunken from her failure to be fash, she soon passed by another stallion, and for the first time, a pony caught her eye in a very attractive way. She eyed him up and down, noticing his chiseled features and especially, the bulge in his ill-fitting pants. The mere sight had sent her pussy into full wet mode, and she could have sworn that her pupils turned to hearts. Grinning wide, her mind suddenly remembered what step five was.

Step 5: Get all of the dick that she needed to feel pretty.

Giggling in excitement, she practically skipped over to the stallion, her hair and tits bouncing in sync as she got in front of him. She saw his amazing physique up close and practically fell down to her knees. She was so entranced that she lost the words to say! She didn’t know how to attract a stallion, especially one as sexy as him! As she felt the panic start to set in, her brain slowly came in. She needed to just let go of that pink lump between her ears and just be true… Say what she meant down there… Between her legs…

“Uhhh, you need something, doll?”

“Hehehe, Dashie needs a dick~”

His eyes widened as she leaned in, showing plenty of cleavage, which prompted a thick bulge to form, before speaking again. “Dashie needs cock now~” She turned around and stuck her ass out, pressing it against his bulge and rubbing it up and down. The stallion didn’t know why, but something about the situation made him feel… Weird. Horny, yes, but something more. He felt this weird tingle in his brain and the more Dash was grinding on her ass, the more he just wanted to…

“Fuck…” He grunted, thrusting against his cock. “Gotta… Gotta fuck…” His toned body hardened with every thrust. His loose fitting pants began to gett tighter as his bulge grew. He began to flex his body more and more, muscles getting stronger. He was slowly developing the body of a sex god as his mind was sanded down to that of a sex machine. In a sudden thrust, his pants burst open, his hard cock landing right between the bimbo doll’s cheeks.

Rainbow Dolly gasped and squealed in pure joy at the catch she had gotten, clenching her fat cheeks together to stroke his cock. The sounds of his grunts and moans made her dripping wet, and that in turn made her giggle. After some teasing, the himbo had enough, and grabbing her ass and squeezing it, he would cram his growing dick into her moist snatch. Rainbow Dolly cried out in pleasure as she arched her back. Her tongue hung out of her mouth as she bounced on his throbbing member. Their moans echoed out, catching the attention of those passing by, and those who heard went to see what that weird moaning was. When they witness the act of public sex before them, they were shocked for a bit, but the more they stared, the hornier they got. The hornier they got, the more their bodies slowly morphed into sexual parodies of their bodies.

However, Dolly didn’t care about any of that. She was focused on the cock her ass was bouncing on at the moment, and it was an amazing cock. It stretched her pussy wide, hitting all her spots with every thrust and making her moan and squeal like the girly sissy doll she had always been. Her tits popped out of her dress and bounced around for everyone to see as mares jumped stallions for their cocks. Every so often, Rainbow would squirt all over her stud’s crotch, but even then, he wouldn’t stop pumping into her. She could only slump with her tongue hanging out as she was slammed.

Soon, she found a stiff cock slide into her drooping mouth, which caused her to jolt up in surprise. Looking up, she saw the abs of a hot, hunky stallion which made her shiver and let out a muffled moan as he used her mouth and tight throat like his own personal fleshlight. Her hands trembled as she lightly took hold of his hips for a bit of leverage, but it was no use. The himbo’d stallions had full control of the situation, and they were going to make use of it. Their thrusts synced up with each other pretty quickly, sending pleasure straight to Rainbow’s brain. Every pulse made her brain get simpler and more dim, slowly wiping away the years of athletic training and ambition to join the Wonderbolts and replacing her focus to pleasuring hot, big-dicked stallions.

Even still, a distant glimmer in the back of her mind was screaming for a way out. She wanted to be free and escape while she could, to be Rainbow Dash. Come on! Her ever fading subconscious shouted as she watched herself getting fucked on both ends. J-Just because it feels really good getting fucked like this… I-It doesn’t mean you should stay some dumb bimbo doll! Push them off! Break free! That was when her peripheral vision caught sight of two stallions approaching her on both sides, their stiff cocks slowly approaching her sides. She very gradually reached out and took hold of them, stroking them with each thrust in her body.

She couldn’t believe it. She was in pure cock heaven. All her mind could think about was stroking and getting her holes filled. Even her inner self panted as she saw herself slowly morphing into what her body was becoming. N-No… her mind said defiantly as she came for the fifth time. C-Can’t let the… Y-Yummy feelings take over… Mmmmm… Her mind’s room warped and shifted before her inner self’s very eyes. Posters of Wonderbolts became pinups of hunky stallions. Her workout equipment turned into a makeup station. The light blues and whites of the room shifted to many different shades of pink. Her sports magazines changed to fashion magazines, the same kind that put her in this. And that was when a vanity mirror appeared before the mental version of Rainbow Dash, revealing that she was wearing girly bimbo makeup. Eye shadow, mascara, sparkling pink lipstick, blush, it was all there.

N-No no no! Her inner self shouted as she tried wiping the makeup off to no avail, looking at her hands to see a perfect manicure. She panicked as her toned muscles slowly softened. Her sporty outfit slowly turned pink as she breathed fast, feeling a tightness in her chest before a massive set of tits shot out, stretching her top to its limits. Her hands shot to her shoulder’s sides in panic, assuming a girlish position as she watched her top turn pink and shiny. Her ass churned slowly, making Dash stick her ass out as it swelled to an obscene size. Seeing it in the mirror as her short shorts slowly became a shimmering pink to match her top, she couldn’t help but give it a few bounces with a giggle. She covered her mouth.

I-I’m not a bimbo! I don’t giggle! She thought. B-But then again… Bimbos do giggle… But I’m not one! R-Right? She slowly stared at herself. She looked like one… She slowly put her fingers to rub herself, letting out moans as she stared at her changing mind. She was in a bimbofying mind, and rather than fight anymore… She was masturbating. Did that mean…?

That was when her mind detected something. A throbbing in her mouth, pussy and hands. The stallions were going to cum. They were going to cum and fill her dumb bimbo brains and pussy with their seed, and all she could do was masturbate harder. I’m… I’m Rainbow… Rainbow, something… She couldn’t remember. What was the other part of her name? She spotted a number of dolls in the corner, perfect bimbo dolls. Her smile widened as she edged closer to her final big orgasm. I’m Rainbow Dolly! P-Please fill my head with that hunky stallion seed!

The pumping got harder and faster as the stallions moved closer and closer to climax, Rainbow Dolly responding by stroking the studs to her sides faster in hopes of being drenched. The stallions shifted in place, moving Dolly back a bit as the original stallion that started this orgy sat back on the ground, hoisting her legs up. Soon, she found herself being bounced on a cock with her other studs rapidly slamming her from all angles. Her mind started going blank before finally, with one final thrust, all four came in unison. Her throat and pussy filled with hot, salty cum while her body, from her hair to her perfect doll tits, got doused all over. Her eyes rolled up as she convulsed, arching her back and leaning against the stallion behind her. It swept her so quickly, it was like the cum shot into her brain and left her with a mind and womb sloshing with cum. All that was the Wonderbolt Rainbow Dash was finally gone. Only the bimbo doll known as Rainbow Dolly remained.

As they pulled out, they dropped their sex doll on the ground, leaving her to drip the cum out all over the ground. She panted softly, drooling out cum as she tried recovering from the savage fucking she had received. That was when she heard hoofsteps coming towards her. She slowly looked up. In her sights were four more stallions, nice and prepped from the orgy that had been happening around her and that she had failed to notice. Their bodies glistened with sweat and their cocks with juices and cum. Just the sight of them made her drool. She wanted them. She wanted more. She slowly sat back seductively. “Like, come and fuck Rainbow Dolly’s perfect pussy~! It’s suuuuper yummy and hungry for your cock~”

She let out a giggle as she was lifted up by two of them, their cocks rising and aiming for her pussy and ass before dropping her down which caused her to moan and squeal in delight. She took hold of the other two cocks and began stroking, sucking on one before swapping to the other and back. It was good to be a doll.

Why was this late?

Internships, college, and family business.
