Rainbow Dash and Rarity have a new favorite spell, one that really brings the two of them together in a way like no other. But with a Wonderbolts calendar shoot coming up, Rainbow Dash has a sexy idea to boost her bust size for the picture shoot...

Rainbow Dash and Rarity have a new favorite spell. Though they didn't understand what exactly it meant by its promises to bring them together when they first cast it, it's become something they can't seem to get enough of. Rarity gets bigger and more sensitive breasts, and Rainbow... well, she gets to be those breasts. It's a sensation like no other for both ponies, but so far they've only done it one way.

That changes with the coming of a Wonderbolts sexy calendar shoot, and a locker room competition that goes on between the mares involved. Whomever ends up with the most popular picture gets to spend two weeks in the Caymare Islands during the team's summer break, and it's a competition Rainbow's determined to win. It would be easy... except for the fact she has the smallest rack on the team.

Good thing there's a spell that increases a mare's chest size, and all it needs is one willing participant...

Contains: Rarity turning into Rainbow Dash's tits, coupled with lactation, mild mind-breaking, and a whole lot of locker room fun.

Cameras and Team-Building Exercises

Rainbow Dash’s house never ceased to amaze Rarity. Apart from the simple fact that she didn’t spend a lot of time at it—it was much more convenient for Rainbow to come down to the boutique than for Rarity to take a balloon or sky carriage up to her marefriend’s cloudhome—the grandeur and proportions seemed eternally at odds with the personality of its occupant. The building was grandiose and elegant, larger than Rarity’s boutique in every way and twice as impressive, with cloud-marble columns and a wispy front lawn of carefully manicured clouds. Rarity knew the only way Rainbow kept it in good shape was through cloudscapers and hired help her father still paid for, despite her rise as a prominent Wonderbolt. She had been surprised to learn when she started dating Rainbow just how wealthy her family was, especially since they didn’t flaunt it like the Rich family. But cloud engineers were paid well, and Rainbow’s father was one of the best…

She made sure her enchanted cloudwalking bracelet was snug around her wrist and the gems glowing before she stepped off of the balloon and onto solid cloud. Her hooves sank slightly into the soft and spongy surface, but it held her weight as if she were as light as a feather. Keeping her eyes locked on Rainbow’s front door, she avoided the temptation to look down at the terrifying plunge all around Rainbow’s lawn and walked forward, away from the edge. She always felt safer when inside Rainbow’s house, at least because the walls and floors made her feel like she was actually on solid ground instead of several hundred feet in the air.

Her hand raised for the doorbell, but the door flew open before it could press the button. Rainbow flew out of the open door and tackled Rarity to the soft cloud lawn, smothering her in kisses. Rarity giggled at the surprise assault and playfully fought back, trying to gently (but not really) push Rainbow away. Finally, after one long smooch, Rainbow grinned and sprawled herself on top of Rarity, not letting her move. “There you are. I was waiting forever for you!”

“Dinner with my parents took a bit longer than I anticipated,” Rarity said, her hand stroking the back of Rainbow’s head. “You know how that goes.”

“Boy, do I,” Rainbow said with a half-grumble. Rarity didn’t blame her; she knew from having dinner with them that Rainbow’s parents were obsessed with their only daughter. It made Rarity all the happier that she had Sweetie Belle as a younger sister to occupy her parents’ affections when she wanted to be left on her own.

Rainbow leaned forward to kiss her again, and her hands began to worm their way to the buttons on Rarity’s blouse. Rarity took the kiss, but she stopped Rainbow before she could undo the second button. “I am not going to be taken outside where everypony can see!” she protested.

“Who’s here to see?” Rainbow asked, gesturing around them. “Everypony else is on the ground, unless you brought somepony else in that balloon.”

“I did not, but it’s just… what if there are other pegasi about?”

Rainbow rolled her eyes and helped Rarity stand up. “If you insist, though one of these days, I’m gonna have to take you up to a cloud and rut you under the stars.”

“We’ll see about that,” Rarity said, leading Rainbow into her own house.

They found the bedroom soon enough, and it didn’t take long for clothes to fly off the bed. Rainbow’s fingers ran down Rarity’s sides, tracing the curves around her waist and hips before following the contour into her ass. She gasped as Rainbow dug her fingers into her crack and squeezed a cheek, and she responded by biting Rainbow’s ear and dragging her down to the sheets with her.

As they tangled each other in the blue sheets, Rainbow managed to wrap her arms and legs around Rarity and hold her in place as the big spoon—ironic, considering Rarity was taller and generally larger than the lithe athlete, but she liked it when Rainbow held her so. It was then that she felt a piece of paper, a familiar scroll of parchment, wedge its way between her breasts like a paper cock getting a titty fuck. Rarity slyly glanced back over her shoulder at Rainbow and winked at her. “Already? I thought you had that calendar shoot you had to do tomorrow. I don’t think Spitfire will let it slide if you’re my boobs during it.”

“I know,” Rainbow said, hands settling around Rarity’s large breasts and giving them a squeeze. “That’s why I want to do it the other way.”

Rarity hesitated. They hadn’t done it the other way before. Usually, she was the one carrying Rainbow in her boobs for the day, gasping at every little brush with her perky nipples and poke at her enhanced bust. Rainbow loved it, and Rarity certainly didn’t mind the earth shattering orgasms that came along with it whenever she climaxed, but she didn’t know how she’d feel if she was the one reduced to nothing more than a pair of tits. She liked having her own body; she didn’t know if being a helpless part of another mare would electrify her like it did Rainbow or terrify her at the loss of her own agency.

“Are you sure?” Rarity asked hesitantly. “I know you enjoy it, but… well, first I suppose I should ask why?”

“It’s a sexy calendar shoot, Rares,” Rainbow grumbled, and her hands gave Rarity’s rack another squeeze. “And I don’t have honkers as big as these. I’m not gonna be the most popular picture in the calendar if I don’t get a little help.”

“I’m not sure I want horny stallions all over Equestria jacking off to you.”

“Who cares? They don’t have the real thing,” she said, planting a kiss in the curve of Rarity’s neck. “It’s more important for the competition.”

Rarity raised an eyebrow. “Competition?” She knew it wasn’t in Rainbow’s nature to lose anything, no matter how trivial it was. “If it’s just some locker room bet between you and your teammates…”

“No! Okay, maybe a little.” Rarity knew from the way she squirmed that she was blushing. “Well, it’s a good bit of fundraising for the team—especially since Twilight keeps cutting our budget to fund another stupid mega-library in some podunk town with twenty ponies in it—so Spitfire tries to encourage us to sell as many calendars as we can. And that means looking as sexy as possible!”

“I still don’t see how this fits into a competition, darling.”

“Well, ponies can also get pinups of the individual shots,” Rainbow said. “So whoever does the best job, Spitfire lets that pony use her pad in the Caymare Islands during our summer break. So long as we don’t trash the place, we can do whatever we want, bring whoever we want…”

Rarity saw where she was going with this, and it made her smile. “I hope you’re alluding to something I’ve always wanted to do…” she prompted, hopeful.

Rainbow didn’t disappoint. “Well, I was thinking, you’re always so busy with your fashion stuff that you don’t have enough time to just get away for a bit, let alone plan a vacation, so if I were to win the competition, then you wouldn’t have to do any of that! It could just be me and you in the Caymare Islands for two weeks! How’s that for a romantic getaway?”

Giggling, Rarity spun around in Dash’s embrace and kissed her, hard. They rolled across the bed from one end to the other, stopping at the edge with Rainbow pinned beneath Rarity’s buxom bust, the scroll still stuck between her breasts. “I think I would like that very much,” she said with a wink.

“Good,” Rainbow said, grinning back. “But there’s no way I’ll win with these sad little puppies…”

Rarity rolled her eyes and took her weight off of Rainbow Dash, stepping out of the bed and prying the scroll out from between her breasts. “Oh, alright, you’ve convinced me. But we better win this competition, especially since I’m the one doing all the work.”

Rainbow’s eyes lit up and she clapped her hands together. “Awesome! Thanks, Rares! And don’t worry, I know we’re gonna win. Who can say no to a pony like me with tits like yours?”

“Whoever they are, I wouldn’t want to be them,” Rarity said. She unfurled the scroll and started to read through the runes, magic building on her horn. “After all, I’ll already be a part of you.”

Rarity felt the familiar tingly feeling settle in across her skin as she cast the spell. It was a spell she and Rainbow had performed several times since they had discovered what it really did a few weeks back. It had caught Rarity’s eye on the promise of bringing a couple together so they could really experience and share their intimacy and pleasure, and it wasn’t until after it had run its course that she realized what it had really done. Rainbow Dash had spent the entire day as Rarity’s breasts, enhancing their size and making them extremely sensitive, and afterwards swore it was the best thing she’d ever experienced. She had liked it so much that she’d willingly become Rarity’s breasts three more times since then, and the orgasms she gave Rarity were out of this world. But so far, they’d never done the reverse.

Rarity supposed that was about to change.

She was a little nervous as she climbed onto the bed with Rainbow, never having been the recipient of the spell’s more drastic effects, though Rainbow did her best to encourage her in her own way: by wrapping her legs around Rarity’s waist and dragging her down to the bed with her. Their fingers entwined and Rainbow quickly found Rarity’s lips, locking hers against them and refusing to let go. The two women rolled and wriggled around the bed, Rarity’s buxom chest pressed against Rainbow’s, her large breasts smothering the smaller boobs protruding from Rainbow’s athletic figure, the mingling of their body heat signifying something more. She felt Rainbow’s nipples poking into her own breasts, but her buxom volume poked back harder. Rarity soon found herself panting for breath as she pinned Rainbow beneath her, teeth tugging on her marefriend’s lower lip as she pulled away.

Rainbow smirked up at her. “You ready?” she asked, moving Rarity’s hands toward her chest.

“I suppose,” Rarity said, hesitantly eyeing Rainbow’s tits. Pretty soon, those little blue balls would be her. “I’m just… you know…”

“Relax,” Rainbow said, kissing her again. Then she placed Rarity’s hands over her blue breasts and pushed. Rarity’s eyes widened as her fingers began to meld into Rainbow’s flesh, and Rainbow shivered and gasped. “You’re… you’re gonna… gonna love it!”

That icy shiver ran up Rarity’s arms and sloshed its way through her core. She felt her muscles weakening as her arms began to meld further with Rainbow’s body, and soon she could do little more than lie on top of Rainbow and pant. Her crotch began to quiver and her tail flicked from side to side in excitement, and she threw herself forward to find Rainbow’s muzzle once more. Rarity closed her eyes and let her lips lock with Rainbow’s, the two mares forcing hot breaths of ecstasy into each other’s mouths as they kissed. Rainbow moaned in bliss and Rarity moaned back, feeling that wet sensation between her legs beginning to spiral out of control.

“Rainbow… Rainbow, darling, I…” Rarity moaned between panting breaths. Whether or not Rainbow could hear her, Rarity couldn’t tell. She could barely tell what was happening to herself as her arms disappeared, and soon her lips couldn’t reach Rainbow’s anymore as the spell reached her shoulders and began to pull her back. Her mind was little more than a pink haze, her attention fully focused on what was happening between her legs. Rainbow accidentally kicked a leg out, lifting Rarity’s body into the air and smooshing her face into Rainbow’s chest. She felt her cheeks stick to Rainbow’s tits, and then her head followed her arms and shoulders into blue flesh.

Her legs kicked and flailed as her vagina contracted with the smell of sex, and that last orgasm followed Rarity into darkness.

The light streaming through the open window the next morning woke Rarity from her sleep. She found herself staring up at the ceiling of Rainbow’s bedroom, white sunlight adding a little energy to the blue walls. Something told her it was too early to be up—especially having sex the night before—but for some reason, she felt well-rested and all but fully awake. Even still, she tried to close her eyes and roll over, pushing her face between the pillows and catching a few more winks of sleep, only to realize she couldn’t move, and she couldn’t close her eyes.

W-What? she thought, and again she tried to move, only to again fail. Was she paralyzed? What happened? She felt like a statue, only… soft and heavy, like she was sagging under her own weight.

When Rainbow Dash yawned and sat upright in her bed, however, Rarity remembered what had happened the night before. I’m Rainbow Dash’s breasts…

She jiggled and bounced slightly as Rainbow’s hands moved to her face to rub the sleep out of her eyes, and then blue hooves kicked off the side of the bed. Rarity inwardly gasped as she bounced about, each little movement teasing and tickling her like a delicate finger run up her thigh—a thigh that didn’t exist. Rainbow Dash sat on the edge of the bed, and Rarity felt her breath on the tops of her soft, round bodies. “Bigger…” Rainbow murmured, her voice making Rarity vibrate. Then two hands appeared in front of her, two enormous, blue hands, and Rarity cried out as Rainbow cupped her breasts with them. “So it did work, then! I passed out while we were doing it last night. How are you feeling, Rares?”

I… I… Oh, Celestia, Rarity purred, feeling every little teasing rub of pleasure run through her boneless form as Rainbow massaged her. Each touch sent her mind reeling, and when Rainbow squeezed one of her nipples, both mares winced and drew back from the intensity of the sensation, one literally, the other figuratively. Rarity, of course, without any muscles or agency of her own, merely hung from Rainbow’s chest as the blood rushing into her nipples stiffened them. So that’s what an erection feels like… I imagine.

Rainbow hopped out of bed and stretched, her athletic back arching as her wings fluttered and ruffled the air around her. A moment of vertigo washed over Rarity as she found herself hanging from Rainbow’s chest and the ground seeming so very far away, given how small she now was. Then, caressing Rarity one more time, Rainbow moved for the bathroom door. “C’mon, Rares, let’s go see how you look!”

She flicked the lights on with the tip of a wing and stopped in front of the mirror. Rarity found herself staring at a reflection of only Rainbow Dash, herself nowhere to be seen. But then again, she was Rainbow Dash now, or at least, a part of her—and a rather prominent one at that. Sure enough, she’d enlarged Rainbow’s breasts by several times, the spell adding some of her own mass to Rainbow’s chest, and now Rainbow looked almost comically disproportioned. It was like somepony had taken Rarity’s large tits and attached them to Rainbow’s little body; she bulged out to the left and right almost past Rainbow’s arms when she held them against her sides. Rainbow had to keep her wings partially extended and arch her back some to keep herself balanced and upright.

“You’re beautiful,” Rainbow said with a grin, her hand massaging around Rarity’s left areola. Rarity saw her close her eyes and bite her lip as tickling pleasure overwhelmed her and Rarity both, and her hooves clopped twice on the tile floor as she struggled to keep her balance. “I definitely couldn’t fly shows like this, but we’re gonna knock that photo shoot out of the park! Fleetfoot’s gonna be so jealous; she’s used to having the biggest rack in the locker room. Not today, though!”

She lifted her right breast up and kissed it, and Rarity felt tingly and warm as Rainbow handled her helpless body so. “C’mon, let’s get ready for the shoot,” she said, purposefully dropping Rarity so she’d flounce heavily from her chest, leaving Rarity dazed from the flood of sensation. Rainbow pivoted about and stepped out of the bathroom, setting Rarity swinging from side to side, and went back to the pile of Rarity’s clothes she’d abandoned on the floor the night before. Her fingers dug out a lacy bra and matching pink panties and slipped them on, hooking the bra tight across her back and giving Rarity a little support from below. “Ha, your bra fits perfectly!” she cooed, gingerly stroking her smooth blue breasts and sending Rarity into a whorl of sensation. “Guess I know what it’s like to carry those melons around all day now, huh? I can’t imagine what it’s like when I’m part of them, too!”

Even though Rarity didn’t have a back, she could feel the phantom ache she got whenever she used the spell the other way around. Her breasts were already big enough, but when Rainbow added herself to them, it was like carrying two turkeys from her chest. At least now she could relax and make Rainbow do all the hard work, but it was hard to relax when the soft, silky bra constantly teased at nipples that didn’t want to go down. And Rainbow kept poking and prodding her, only making things worse…

Rainbow finished getting dressed, throwing a loose t-shirt and jacket over herself and Rarity, since Rarity had made fitting into any of her other clothes impossible. Rarity lost her sight when Rainbow zipped up the jacket (how could she see in the first place?), though Rainbow gave her a comforting squeeze as she found herself in almost total darkness. “Don’t worry, you’ll be able to breathe some for the shoot,” Rainbow assured her. “I just can’t thank you enough for doing this for me, Rares. That competition is as good as ours. I don’t know how I’ll repay you in the meanwhile. You’re the best!”

I can think of a way, Rarity thought, even though Rainbow couldn’t hear her. After all, Rainbow had sworn up and down that the orgasms she’d experienced as Rarity’s breasts were second to none…

There was perhaps some irony to Rarity that flying felt far more natural as Rainbow’s tits than whenever Rainbow carried her in her arms and took wing. At the very least, the bra kept her held snug against Rainbow’s chest, safe and secure, with only a little bit of jiggling up and down with each beat of her marefriend’s wings. Though perhaps the best part was hearing Rainbow’s muffled curses as she tried to fly with a now much heavier and less aerodynamic chest.

The flight to the studio where the shoot would be taking place only took a half hour, but Rarity quickly lost track of time with each little bounce and jiggle of her boneless form. Celestia, even Rainbow moving was leaving her aroused and desperate for some sort of release. Why did Rainbow want to be like this all the time? The building tension and frustration was driving her mad! She tried desperately to move or do anything on her own, but she was completely inanimate and helpless. She truly was just a pair of breasts, and like a pair of breasts, there was nothing she could do but patiently take life one jiggle at a time.

It was a good thing the spell only lasted for twenty-four hours… A week of this would be downright tortuous.

Her whole form shook when Rainbow’s hooves finally made contact with hard ground, and if she could, she would have shrieked with bliss as her sensitive flesh rubbed against the bra on all sides. Rainbow felt it too, her breath hitching as she came to a stop, and her fingers prodded at Rarity through her clothes. “Definitely felt that one,” she muttered, though to herself or to her marefriend, Rarity couldn’t tell. But soon she was bouncing along again, the movement dulled and controlled somewhat by Rainbow’s underwear, and she tried to imagine just from the sounds around her if Rainbow was at the studio or not.

“Hey! Crash!” Rarity could tell from the voice that it was Spitfire, and Rainbow came to an abrupt stop, Rarity bouncing upwards as Rainbow stiffened her spine and saluted. Hoofsteps came closer, and Rarity could imagine the Wonderbolts captain standing directly in front of Rainbow. “You’re late. The other girls have already gotten started with their shoots. I sent the new girls out to get some coffee for us while we finish up, so it’s just the regulars now.”

“Sorry, ma’am,” Rainbow quickly apologized. “I was just, uh, getting ready for the shoot.”

“I can tell,” Spitfire said, and then Rarity quietly squealed as a hard finger poked directly into her. “How much padding did you need for that, flat-chest?”

“I have a friend who knows a spell,” Rainbow said, her voice saturated with cocky smugness. “I hope I’m not making you too jealous, ma’am.”

“Jealous?” Spitfire scoffed and swatted Rarity again, setting her jiggling. “I know you couldn’t possibly fly straight with those things, Crash. This better not be a permanent addition.”

“It isn’t, ma’am,” Rainbow assured her, though Rarity felt her stagger from the sensation of Spitfire’s swat to her chest. “Just for today.”

“Good. Otherwise Fleetfoot might murder you in your sleep, and I don’t want my best wingpony dead and useless in a show. Now get going, and maybe you’ll win the competition after all.”

“Ma’am, yes ma’am,” Rainbow quickly said, saluting again and walking away when dismissed. Rarity could still feel the afterglow of Spitfire’s touch tingling through her, and when Rainbow finally removed her jacket and t-shirt, the sudden return of light snapped her back to the present.

Blue fingers once more fiddled around the edges of the bra, pushing and prodding Rarity this way and that. “Well, it’s about time for the shoot,” Rainbow said, and she gave Rarity a squeeze that left them both shuddering in delight. “We’re gonna have a lot of fun when we get back to my place, I promise you that.”

Rainbow left what Rarity could only assume was the changing room behind, and she heard the distant snap of flashing studio lights and the faint click of a camera shutter. Mares’ voices drifted across the empty space, and Rarity could very faintly make out a group of athletic pegasi standing off to the side while the photographer gave instructions to their subject. Somepony whistled as Rainbow approached, and suddenly those figures were standing around the two of them.

“Wow, Crash, nice rack,” somepony said… Misty, maybe? Despite how often Rainbow brought Rarity to Wonderbolts gatherings, Rarity sometimes still had a hard time placing names to faces. It didn’t help that every little shift of Rainbow’s body distracted her thoughts as she bonelessly jiggled on her marefriend’s chest.

“Damn!” exclaimed a mare who Rarity was pretty sure had to be Blaze. “How’d you do that, Crash? No amount of padding could make your tits look like that!”

Rainbow snickered and kicked a hip out to one side, hand teasingly resting on the band of her panties. Rarity was simply surprised to see Rainbow imitating the seductive pose she used on her so many nights before a roll in the metaphorical hay; maybe she had learned something from her after all. “No padding involved,” she boastfully proclaimed. “Just a little help from a friend.”

“She knows Princess Twilight, remember?” Surprise asked. “A little bit of magic can go a long way.”

“Yeah, but that’s cheating,” Misty said. Rarity vaguely saw the mare cross her arms beneath her breasts, now much smaller than the pair Rainbow sported. “Who’s gonna appeal to the itty bitty titty crowd now, Crash?”

“Guess that’ll have to be you, Dizzy,” Rainbow retorted. “I’m sure they’ll love you.”

The other mares giggled, and Rarity heard the camera shutters snap closed again off to the right. Blaze raised her voice in response. “You done, Flatfoot? Check out Crash’s rack!”

“Why would I want to look at Crash’s landing strip?” came the taunting reply. “It’s flatter than a runway!”

Rarity jiggled as Rainbow shifted her weight from one hip to the other. “Oh yeah?” she asked, and Rarity inwardly gasped as Rainbow put her hands under her breasts and bounced her marefriend up. “How’s this for flat?!”

When Rarity’s blurry vision stopped shaking (and the sensations had faded enough for her to think straight again), she saw Fleetfoot’s silhouette standing across from Rainbow, arms and wings somewhat extended in surprise. “Celestia, those things can’t be real!” she exclaimed, peering closer. “What did you do to them?”

“You’re just jealous my tits are bigger than yours,” Rainbow teased.

“Tsch! As if…”

The whole conversation made Rarity’s head spin—not because it was confusing, but because it was surreal. As far as everypony else was concerned, and even Rainbow to some extent, Rarity wasn’t a pony or a person. She was just a pair of voluptuous breasts attached to a Wonderbolt. She had no agency of her own, and nopony treated her like a person. She was just a thing, an object, a pair of tits to be ogled and played with. There was nothing she could do about it… and that helplessness left her strangely aroused.

“Well, whatever you did, let’s see if you’ve got what it takes to win the competition,” Fleetfoot said, walking up to Rainbow and firmly groping her breasts. Ecstasy overwhelmed Rarity as Fleetfoot’s hands squeezed and fondled her, and the fact that it wasn’t Rainbow—wasn’t part of what was now her own body—only seemed to make the feeling that much more intense. “Holy shit, Crash!” Fleetfoot exclaimed, almost in disbelief of what she was feeling. “These things are, like, tumors! You go and take your marefriend’s rack for this?”

The irony wasn’t lost on Rarity, she just scarcely could comprehend it due to the sensations running through her. Rainbow Dash, too, struggled to stay upright and clear-minded. “H-Hey, knock it off,” she said, her voice hitching slightly as Fleetfoot stimulated her hypersensitive breasts. She managed to shove the other Wonderbolt back and retreat a few steps to safety. “You’re not helping.”

“Not helping?” There was something in Fleetfoot’s voice that made Rarity worry she wasn’t done yet, but she didn’t come any closer. “I can give you a lesson or two in having a big bust, Crash, once you’re done with your shoot. You gotta make the most of it while you got it.”

“Don’t worry, I intend to,” Rainbow said, crossing her arms underneath Rarity and propping her up some. “Starting right now!”

Rarity helplessly bounced up and down as Rainbow jogged over to the studio stage, her vision flopping along with the rest of her boneless bodies. Every time Rainbow moved her arms, they brushed against Rarity’s bulging sides, and the bra seemed to concentrate the sensation throughout her core. By the time she came to a stop, Rarity was a complete and utter mess, her mind dashed into a dozen different thoughts, all struggling to comprehend the constant stimulation and arousal running through her form. She vaguely heard the photographer give Rainbow some instructions, and then she jiggled again as Rainbow changed her pose accordingly. There was a bright flash that pierced through the fabric of the bra and dazed Rarity’s unblinking gaze, and then Rainbow was trying another pose, swinging Rarity along with her torso.

Swing, flash. Jiggle, flash. Every change in Rainbow’s pose set Rarity moving in one way or another that sent ripples of pleasure through her form. At one point, Rainbow lay down on her stomach and loosened the bra so the straps hung low on her arms, squashing Rarity into the floor of the stage and making her spread out and flatten some. She quietly moaned as Rainbow rocked slightly on her, and she felt Rainbow’s heart rate quicken as she accidentally stimulated herself in that pose. Rarity knew the struggle all too well; whenever she had Rainbow as her breasts, it felt like every little touch and rub was about to set her off. She wondered if Rainbow was regretting the spell now, given how much need had to be building between her legs.

And then it was over, and Rainbow left the stage behind with a little bit of sashay in her walk. The other Wonderbolts mares all stood off to the side, though what their expressions were, Rarity wasn’t quite sure. “The competition’s as good as mine,” Rainbow taunted them. “You girls don’t stand a chance!”

“We’ll see about that,” Misty said, and Blaze snickered over her shoulder. “It’s gonna take more than your fake boobs to sell the most pinups.”

Fake? Rarity thought, surprisingly annoyed. I assure you, darling, I am most certainly real!

“Jealous…” Rainbow sang, skipping off without them. “See you girls for practice on Monday!”

In a minute, Rarity found herself back in the changing room with Rainbow. Rainbow stopped in front of the mirror and posed a few times, turning this way and that to prominently display her marefriend-enhanced bust. “We got this in the bag, Rares,” Rainbow said with a grin, and she gently ran her fingers in circles around the topside of Rarity’s halves, leaving them both shuddering in teasing pleasure. “Those weeks off in the Caymare Islands are as good as ours!”

Through the bliss-fueled confusion, Rarity mentally hummed in agreement. A romantic getaway for just her and Rainbow would be perfect.

She vaguely heard the door open behind her, and Rainbow whirled around in surprise. “Hey, what are you girls doing in here?” she shouted at them. “You know what ‘occupied’ means?”

“Relax, Crash, we just wanna see a thing… or two,” Fleetfoot said.

“Yeah, you can’t just walk into the studio, flaunt those bowling balls around, and then leave without letting us get a good look at them!” Misty said, and Rarity saw the pegasus’ silhouette step closer. “We gotta know your secret!”

“Magicians never reveal their tricks,” Rainbow said, angling Rarity away from outstretched hands. Rarity was pretty sure she stuck her tongue out at them as well.

“I bet they’re just pads,” Surprise scoffed.

“They’re not!”

“Yeah? Prove it then!” came Blaze’s challenge.

Oh, don’t you dare, Rarity thought at Rainbow for all the good it did. I am not a toy for your teammates to play with!

But Rainbow Dash wasn’t one to back down from a challenge. “Fine!” she shouted back, and Rarity felt the bra keeping her safely cocooned loosen as Rainbow moved her hands to her back. Soon it fell away entirely, letting Rarity clearly see the other Wonderbolts standing in front of Rainbow… all in their underwear. She felt a spark of arousal stimulate her fancies for all the beautiful, scantily-clad women in front of her, but more immediate concerns chased them off—like Fleetfoot’s hands reaching for Rainbow’s chest again.

“Hey, who gave you permission?” Rainbow asked, swatting Fleetfoot’s hands away.

“Permission? We’re higher rank,” Misty said, sticking her tongue out. “Come on, we just want a feel. I’ll let you touch mine if you want.”

“We slap each other’s tits all the time in the locker room,” Blaze said. “You do too. How’s this any different?”

Rainbow Dash didn’t have a good answer for that; instead, she groaned and puffed her chest out some, as if she was trying to put her boobs as far away as possible. “Fine, one squeeze, you jealous bitches. Just to prove they’re real.”

“Magic doesn’t make them real,” Fleetfoot said, though she took the opportunity regardless. Rarity trembled and moaned as Fleetfoot explored her curves with slender fingers, giving a pinch and a prod here and there. It was much different than the rough tug she’d given before the photo shoot, even if it was still groping and fondling. It was more sensitive, gentler even, as if she knew she was driving Rarity crazy and was doing it on purpose. But there was no way she could’ve known; there was no way Rainbow would tell any of her teammates what she was up to.

Right?

Rainbow sucked in a stuttering breath as Fleetfoot rubbed her extremely sensitive breasts. “O-Okay, you had your squeeze,” she said, and Rarity felt her heart rate quicken at the stimulation. A trickle of hormones began to enter her blood, spreading throughout Rarity and making her hornier as a result. Slowly, Fleetfoot’s touch turned from overwhelming and distracting to something she wanted, something she needed. And when the Wonderbolt’s fingers stopped for a few seconds, she cried out in dismay as the feeling stopped along with them.

“Just one squeeze?” Fleetfoot said, raising an eyebrow while the other mares giggled. “You getting off on this, Crash?”

“N-No!” Rainbow hastily blurted. “Just… you’re groping my breasts! Of course it feels great!”

“She’s sensitive,” Misty said with a wink. “Why don’t we help her out?”

“They’re real enough,” Fleetfoot observed, and Rarity yelped in pleasure as her thumb found an upright nipple and pressed it back down. “Whatever spell you pulled, Crash, you gotta show it to the rest of us!”

“Her wings are straight up!” Blaze said with a guffaw. “C’mon, Flatfoot, give her a little more!”

“Girls…” Rainbow feebly protested.

“Don’t act like you don’t like it,” Fleetfoot said. When Rainbow mumbled something in protest, she rolled her eyes. “I promise I’m not gonna kiss you, Crash. Sheesh, we know you’re dating Rarity. This is just a little, let’s call it locker room fun between us girls.”

If Rarity had been able to focus at the moment, she would have protested what was happening. Instead, she could only cry out in silent bliss as Fleetfoot continued to massage her, kneading her nipples between her knuckles. It was so horribly wrong… but it felt so horribly right. As the stimulation and ecstasy crashed over her in waves, she didn’t care who was playing with her anymore. All she knew was that she wanted to be played with, and she wanted it bad.

She knew Rainbow wasn’t taking it much better than she was. The Wonderbolt whose body she was merely a part of could only moan and moan in pleasure. More hormones emptied into her bloodstream, and Rarity found herself absorbing them by the breastful. They sent her need skyrocketing, and she wished she had a vagina to stick her fingers in right now. But she had no vagina and no fingers to stick in it, leaving her riding on the edge of climax without being able to take the initiative on her own and finish herself off. She was wholly reliant on Rainbow Dash for that, it seemed, and Rainbow was trying her hardest to not get too aroused by Fleetfoot’s touch.

Yet she was failing miserably. Fleetfoot managed to pull her away from the wall, sitting Rainbow down on the bench hard enough to make Rarity bounce and jiggle. Rarity squawked in distress and pleasure, and Rainbow did much the same, her voice hitching in her throat. “C’mon, let me have a go!” Misty said, shouldering Fleetfoot out of the way and quickly cupping Rarity in her hands. She gave each half a solid squeeze, making Rarity squeal in delight, and she grinned at Rainbow. “I’m not gonna make any promises like Fleetfoot,” she said with a wink, and she lunged forward and put her lips right against Rainbow’s.

Rarity didn’t care; her world was reduced to only what was happening right around her. Misty knocked Rainbow onto her back on the bench, using her weight to pin Rainbow down on the wood. Suddenly, Rarity felt herself squished against Misty’s breasts, smothering the blonde mare’s smaller tits with her own buxom volume, and she could feel the sweat coming off of Misty’s chest and sticking to her. Rainbow moaned aloud while Rarity moaned within her chest, and bit by bit, Rarity felt a pressure building up inside of her that she knew had to burst, one way or another.

The two mares squirmed on the bench, though Rarity didn’t know if Rainbow was fighting Misty off or reveling in the overwhelming waves of passion wracking her from head to hoof. Frankly, she didn’t much care anymore. All she wanted was for Misty to finish the job, to give her the relief she so desperately craved, that earth shattering orgasm that seemed to taunt her with how close yet so far away it seemed. The mashing of Misty’s breasts against her face, for as much as she had one (or two, even), drove her utterly mad. Her entire bodies bounced and jiggled and deformed under the other mare’s assault, and every little tiny ripple sent another pang of pleasure through her halves. Celestia, just let me cum!

But Rainbow crossed her legs and fought it off as best as she could. On the one hoof, Rarity admired it; she knew her marefriend was thinking about her and what exactly she was going through right now. On the other hoof, she hated her for it. Rarity didn’t care what the other Wonderbolts were doing; she wouldn’t have cared if Rainbow let the whole team grope her and fuck her at this rate! All she was doing was delaying the inevitable, stretching Rarity to the absolute extreme lengths of her patience and sanity while she waited for release that just wouldn’t come. Misty squeezed and scrunched each of her halves between her fingers, playing with all the fat in her hands. That was all Rarity was now; that was all she’d been reduced to, even in her own mind. I’m a pair of breasts! she screamed inside her mind, and the thought carried ecstasy and joy behind it. Just squeeze me, grope me, play with me! That’s all I’m good for! All I want!!!

It was as if her prayers were answered, because Blaze and Surprise stepped up for their turn, moving Misty out of the way. They both grinned down at Rainbow, who’d been reduced to a panting, quivering wreck on the bench, and then their eyes turned lower. Rarity saw them looking down at her, each fixated on one perky nipple standing upright, and she immediately knew what they were thinking. When they closed their eyes and pursed their lips, Rarity found herself squealing in anticipation.

Their lips settled around her nipples, and they began to suck.

Everything she’d experienced up to that moment paled in comparison to the utter tsunami of pleasure that rocked her. She felt like she was being turned inside out at their touch. There was no coherent thought left to her mind anymore; it was utterly broken. She was doing her job as a pair of breasts, to be suckled on and teased with teeth and tongue. Blaze and Surprise were helping her fulfill her purpose, her only purpose, and the identity of Rarity the fashion designer began to crumble in her mind, replaced by Rarity the pair of tits.

And the way they went about it was so different that they stimulated her halves in different ways, creating a confusing dichotomy that made her lose all sense of herself. Surprise used her lips and tongue to great effect, sucking the nipple into her mouth where her tongue could swirl over the perky point, never going in the same pattern twice. Rarity could feel the massage of her tongue arousing her all the way to her core, where she felt a few twitches and stirrings of the hidden ducts deep inside as they prepared to empty. Blaze, however, was much more aggressive. She used her neck as much as she used her mouth, jostling Rarity this way and that, and she would occasionally nibble with her teeth. Rainbow gasped and moaned every time Blaze nipped at her nipple, and the sensation was like a shot of lightning straight through Rarity’s right half. Swirling and sucking on her left, jostling and biting on her right—the two stimulations were so different yet each so powerful that Rarity felt like she was about to burst… and Rainbow still hadn’t cum yet!

But she was close—Celestia, she was so close! Rainbow’s heart wildly fluttered, and her panting bobbed Rarity up and down with each breath she took. Her words were long gone, replaced only with a blissful moan that droned on and on, yet her legs still squirmed as she tried to keep herself contained. But she was on the verge, just as much as Rarity was, and she wouldn’t be able to hold it back for long.

Rarity didn’t know who did it, whether it was Blaze or Surprise, but one of the mares sucking on her moved a hand to Rainbow’s crotch and pressed between her legs. It was like pressing a button, and all at once, Rainbow climaxed, unable to hold it back any longer. It felt like liquid fire shot through her blood, saturating it from head to hoof, and seeping into every inch of Rarity’s two halves. Rarity screamed in ecstasy as Rainbow’s orgasm shook them both, and that was the release she’d finally been waiting for. With a shudder, she felt her hidden muscles clench hard, and she began to lactate as her ducts finally emptied themselves. Her nipples stood upright and hard, a perfect duct to expel the creamy milk pouring forth from her bodies, directly into the sucking mouths of Blaze and Surprise. She ejaculated milk as hard as she could, feeling unimaginable pleasure permeating every cell of her simple, fatty being. It was an orgasm unlike any other, magnified and multiplied tenfold by Rainbow’s own orgasm and the sensation of the two mares suckling at her tits, drawing off more milk with every squeeze of Rarity’s nipples.

The climax seemed to last for hours, maybe even days. There was no way for Rarity to keep track of time, there was only an unimaginable high that seemed to surround her and fill her through infinity. Vaguely she recalled the extreme orgasms she experienced whenever their roles were reversed, but she was still a pony then, still a woman, and she had parts of her body that weren’t entirely devoted to sex and stimulation. Not so here. Here, she was purely sex and pleasure, something to be played with and sucked on, and her entire being was devoted to and absorbed in the climax. She couldn’t imagine anything else… not that she would have wanted to. She couldn’t even remember her name, not that it mattered. She was Tits, and she had done what she was designed to do, reveled in what she was supposed to revel in. Now, as the climax began to fade into a potent afterglow, Tits couldn’t wait to do it again.

The two Wonderbolts backed off, white liquid dribbling down their chins, and smirked at each other. “Holy shit!” Fleetfoot exclaimed from somewhere out of sight. “You girls really did her dirty!”

“Can’t say she didn’t enjoy herself,” Misty commented, gesturing in Rainbow’s direction. “Her panties are sopping wet!”

“You smell that? It’s about enough to get me going!”

“I can’t believe she was lactating! That spell must be some powerful shit!”

“It tasted as good as it looks, believe me!”

Rainbow’s tits slowly pulled together enough pieces of sanity for a coherent thought while their owner lay helplessly on the bench, her mind scrambled by the overwhelming orgasm. I can’t wait for Rainbow to use me again…

The door opened out of the corner of her vision, and all the Wonderbolts jumped back at another mare’s sharp voice. “What in Tartarus are you bitches doing in here?” Spitfire demanded, and soon her yellow face wandered into view. She looked down at Rainbow disapprovingly and sighed, crossing her arms with a frown. “Seriously? Again? Can you sluts go one week without getting each other off?”

Nopony had an answer for that, it seemed, so Spitfire pinched at the bridge of her nose in exasperation. “Go put your fucking clothes on, ladies. Flatfoot and Dizzy, go find some spare panties for Crash, and Slowpoke and Hot Sauce… clean that shit up, will you?”

A quartet of “Ma’am, yes ma’am’s” answered Spitfire, and the other four Wonderbolts scurried off to gather up their clothes and execute their captain’s orders. Spitfire, meanwhile, stood over Rainbow Dash and shook her head. “Guess those tits ended up being more than you bargained for, eh, Crash?”

Rainbow Dash weakly moaned out a “Yes, ma’am,” but failed to move her arms to even attempt a salute.

“Thought so. The rest of those girls need to go find a date instead of jerking each other off in the locker room all the time.” She stooped over and picked up Rainbow’s forgotten bra, dropping it on top of her breasts and obscuring their vision. “Since they seemed to love your rack so much, I think they’ll be more than happy to forfeit the competition for it. Go get yourself cleaned up, then go home and pack your bags for the Caymare Islands. The party house is yours for the summer break.”

“Thank… you… ma’am…” Rainbow murmured.

Spitfire chuckled and turned away. “And go take a shower when you get home, Crash. Your vagina stinks like nothing else.”

It was a few days later when Rarity heard a knock on her boutique door. At first, she ignored it; she was much too invested in her work, and if she ignored it, maybe the offender would just go away. But the knocking continued, followed by a familiar scratchy voice. “Hey… you in there, Rares?” she heard Rainbow say. “Can you… open up?”

Rarity pointedly frowned and went back to her work. Rainbow was the absolute last pony in Equestria she wanted to talk to right now. Not after what had happened following the photo shoot.

But Rainbow Dash was persistent, and the knocking continued. “Look, Rares, I know you’re in there, and I’m not gonna go away. Can you just… open the door? Please?”

Knowing full well that Rainbow meant it when she said she wouldn’t leave, Rarity finally stood up and stormed her way downstairs. She unlocked her door and opened it just a crack, the chain stretching taut just in front of her eyes. “What do you want?”

Rainbow wilted under the harsh tone in Rarity’s voice. “I just… wanted to say I’m sorry,” she said, and when she moved, Rarity saw the bouquet of flowers in her hand. “About… well, you know.”

Rarity narrowed her eyes. “No, I don’t know,” she lied, just to make Rainbow squirm.

“Y’know, the thing in the changing room…” Rainbow huffed and her wings sagged. “Look, it was very uncool, I get it. And if you’re pissed at me… well, that’s fine. I definitely deserve it. Things got… out of control.” She scratched the back of her neck with her free hand. “None of that shoulda happened; the other girls were being dicks, but I should’ve gotten you out of there. But once they started… well, you know what that’s like, right?”

Rarity certainly knew all too well; the hypersensitivity didn’t leave a mare with a whole lot of brainpower left for rational thought or action. But she didn’t let that show on her face. She was mad at Rainbow, and she didn’t want to let it go just yet.

In the awkward silence that followed, Rainbow scuffed her hoof on the ground. “A-Anyway, yeah, I just wanted to say I’m sorry, and if you don’t want to see me again, that’s cool… that’s cool. I’ll just, I don’t know, move to Whinnyapolis and change my name to Ethan or something, and I won’t ever bother you again. I just… y’know…”

Rarity didn’t let her blubber on anymore and shut the door in her face. She heard Rainbow sigh in defeat on the other side, and her hooves scuffed on the ground as she made to walk away. But before she could do so, Rarity undid the chain and fully opened the door. Rainbow froze in place, moments from taking off, and looked back over her shoulder to where Rarity stood, hands on her hips. “Rainbow Dash.”

Rainbow blinked and turned around. “Y-Yeah?”

“I am very upset with you right now,” Rarity began, pinning Rainbow down with a look. “…But I’m more upset with your colleagues. They’re the ones who made things get out of hand, not you. And, for what it’s worth, it was definitely one of the best experiences I have ever had in my life.”

Rainbow was at a loss for words; surprise and shock were plainly carved into her face. “O-Oh?”

“When your entire being is devoted to pleasure, how could it not be?” Rarity flickered a ghost of a smile at her, but quickly forced it back down into a frown. “I do not blame you for what happened… at least not in full. Okay, I blame you a little. And you’re going to have to make it up to me now.”

“Yeah! Of course!” Rainbow eagerly stepped forward, flower bouquet awkwardly held between her hands. “Anything you want, Rarity, I’ll do it!”

Rarity raised an eyebrow. “Anything?”

“Anything! I swear!”

Rarity’s frown turned into a sly grin. “Well, in that case…”

She stepped away from the door, beckoning Rainbow in. Rainbow practically ran in after her, as if she feared that the chance for redemption would be gone if she took too long. The moment she stepped inside, Rarity grabbed her by the shoulders and kissed her, long and hard. When they separated, she leaned Rainbow back in her grip, looming over her. “We’re going to the Caymare Islands on that competition I won for you,” she finally said, a mischievous twinkle in her eye. “I’m going as your breasts so I don’t have to sit in those cramped airplane seats for hours on end, and you’re going to deal with it and all the sensations that come with it in public and not let anypony touch me.” She smirked as she added, “That’s about as cruel a punishment as I can think of without being overly sadistic.”

Rainbow blinked, looking down at her breasts, then back up at Rarity. “That’s... it?”

“Did it sound like I was finished?” Rarity shook her head. “We have two weeks there, and for the first week, I’m doing whatever I want to you. If I want you to be my tits while I tan, then that’s what’s going to happen. If I want to take you to the spa as my rack, then we’re going to the spa with you as my rack. Maybe I’ll see if Twilight has any other odd spells like this stuffed in her library, but I digress.”

She jabbed her finger into Rainbow’s little boob and let a wicked grin settle across her muzzle. “You’re mine for that whole week, Rainbow, and I’ll pay you back that little changing room fun we had the other day tenfold.”

Rainbow weakly smiled; Rarity knew from the way she fidgeted she wasn’t sure if she was supposed to be scared or aroused. “Done deal,” she said, at least remaining loyal to her promise to do anything.

Rarity smirked at her. “Good. Then for the second week, we can do things together as a couple. I figure by then we’ll have gotten most of the kinkiness out of our system, hmm?”

“Of course!”

“Good.” Rarity stood Rainbow upright and finally released her, then put a hand on her hip, kicking it out to the side. “Tonight, however, I’m going to use the strap-on and take out a little frustration on that tight little ass of yours. That’s not part of your punishment; I just want to make you squeal. I think I’ve earned a chance to blow off a little steam, and I’m not gonna stop until I hear you sing.”

Rainbow wilted and nervously grabbed her ass cheeks in response, but she still managed a smile. “Whatever you say, Rares…”

Rarity smirked back at her. “Well, with that, darling… apology accepted.”
