How to Use Your Hyper Bra
“Alright, and that…should be…the final…touch!” Rarity announces with some cheer managing to show through her weariness, letting out a deep sigh of relief.
Twilight Sparkle takes the elastic strap from her and tugs on it, watching the way it stretches. Then she uses her magic to grip the clasp at the end of it and pull harder still; the strap is able to stretch from the floor to the ceiling without breaking (Rarity tenses visibly while watching this). “The tensile strength appears to be sufficient,” she remarks before proceeding to do the same test to the other elastic straps that are part of the huge bundle on the floor in front of them.
There is a loud groan. “Rarity said it’s done, do we really need to go through all this?” Rainbow Dash asks. The pegasus is sprawled upside-down in a nearby chair, legs up over the back rest.
“It’s of the utmost importance that we get the specifications sorted out exactly to our needs, Rainbow,” Twilight replies without turning away from her task at hand. “We wouldn’t want you leaving only for this to fall apart immediately.”
Rainbow groans again and flops about in her seat.
“It’s okay, Twilight,” Fluttershy interjects, at least as much as she can with her soft squeak of a voice barely being audible, “I appreciate all of you going to so much effort to help me. I’m sorry I’m such a…such an inconvenience.” Her voice turns quieter still as she chews on her lip. She can’t help absentmindedly pawing at her chest, as she so often does.
Twilight inhales and makes a long exhalation. “We’re just doing what we can, Fluttershy,” she mutters.
Then the alicorn uses her magic to lift the whole mass of fabric upward, making its true shape clear. It consists of two huge cups of silky cloth, roughly triangular, with one elastic strap tethering them together at one corner each and another long band from every other corner. It is clearly a bra, albeit of such a scale that it could be used as a pair of tarpaulins. It also features the notable addition of a series of sapphires and amethysts sewn into the outer surface of the cups, making them sparkle and glitter.
“Alright, here,” she says while she lets the oversized garment float over toward Fluttershy, “let me get this on for you.”
“O-oh, no, Twilight, that’s fine,” Fluttershy blurts out hastily. She backs away, not that she can budge very much without support, though it’s easier for her to drag backward than push forward. “I-I can…do it myself, just…just hand me the straps.”
Twilight stares back at her with her lips pursed in a thin frown, that expression that she wears so often these days—weary, pitying, her patience taxed. Rarity and Rainbow Dash bear similar looks upon their faces, their worry clear. Fluttershy feels a pang of guilt, but still she stays her course, determined upon this line of action. “Very well,” she finally replies, sighing again through her nostrils, and the elastic strands stretch closer toward the pegasus, allowing her to take the ends of each of them.
“Thank you, Twilight,” she says with a pithy nod before she turns her attention toward the task awaiting her, the bra for her to put on, and the expanse which sprawls out in front of her. Her heart thumps loudly in her chest.
It’s a lengthy process. The straps end in clasps that link together behind her back, but she starts by only connecting the two on each side. Then she shakes them all, letting the bra cups billow out in front of her so that they settle at the far end of the great mounds that comprise her bosom. The butter-yellow globes are far too broad for her to reach around their circumference, too broad for her to even touch her own nipples, a single one of them large enough to outstrip her body’s mass several times over. They rest firmly upon the floor in front of her, making it nearly infeasible for her to walk without some form of external support, though getting that support to begin with isn’t much easier, as Twilight and Rarity would attest to.
With the bra settling around her, Fluttershy is able to tug on the straps so that the garment tightens around her. The action is still easier said than done as she has to jostle the huge bulk of each breast in order to get them into the proper positions, and with each being the size of a boulder that’s a lot of bulk to have to move. There is more musculature around her frame than there once was, a thin layer of sinewy padding to a body that had been thin and willowy, built from the effort of carrying herself as she reached her current size, but that is still not nearly enough to offset the burden upon her.
Finally she manages to pull on the bra and bring it closer to her, squishing the twin mountains against herself as she affixes the clasps behind her back. The straps dig into the pillowy flesh slightly, and the great valley of cleavage in front of her pulled upward. It certainly serves to make her a little more publicly presentable—not that Fluttershy goes out in public very often anymore; being technically decent doesn’t override the sheer innate obscenity of her bust—but it still isn’t going to make much of a difference in terms of giving her what she needs to stay mobile. That’s when Twilight Sparkle approaches her, circling around the obtrusive frontal mass, and this time she’s more insistent upon taking direct action.
“This is what will allow you to control the amplifier for the enchantment,” she explains while she takes Fluttershy’s right hand and slips a band around her wrist. The braided string is thin and delicate enough that she scarcely feels it, only the weight of the gemstones which are set into it, two pale pieces of pink quartz on either side of a sliver of jade, carved into the shape of a butterfly like her cutie mark. Fluttershy coos quietly in amazement, as if it is a mere piece of jewelry instead of a part of a complicated magical system. “You hold it up like this,” Twilight continues, raising Fluttershy’s arm up in front of her, as one would look at a watch, “and you press this side to reduce the effects of the enchantment.” She touches the left wing of the gemstone butterfly, which is pointing downward now that it is rotated ninety degrees. “And you press this side to increase it,” she concludes while pushing the right wing, and in response the gems start to glow.
Fluttershy gasps as she feels a tingle of magic ripple through her, cradling her bosom. It feels akin to the tingle of a levitating aura, as Twilight would employ when she has to manually lift the pegasus’s gargantuan assets. It feels gentler, though, a faint warmth which suffuses the fabric of the bra and radiates throughout her. Though she can’t readily see it from this angle, the gemstones which are sewn into the cups have started to glow with a faint light. She feels just a little lighter, enough that she can drag her breasts across the floor without feeling much friction, as if their undersides have been coated with grease.
“The lowest setting should be enough to give you mobility in a pinch,” Twilight says as she points to the center of the butterfly gemstone, where there are five little notches bored into the jade, pink light emanating from one of them. “I would suggest, though, that you keep to the second or third so you don’t chafe too much.” She presses on the wing two more times and Fluttershy stifles a croon in her throat as the magical aura intensifies, suffusing its heat through her. The bra clenches tighter around her chest while rising, bringing the twin globes up into the air, enough that they fully cease contact with the floor.
“Oh, wow, gosh…!” A giddy smile stretches across Fluttershy’s muzzle. She cups her arms underneath the immense breasts and lifts gently, feeling them bounce and bob in her grasp. Their weight is still present, pulling upon her back, but enough has been displaced that it’s like they have gone from being merely balloon-like to actual balloons. She’s sufficiently engrossed with observing these effects that she scarcely notices Twilight continuing to speak in the background about her recommendations for the device—something about absorbing ambient magical energy, something about not keeping it on high for too long or the charge would run dry, etcetera.
“Now hang on, Twi,” Rainbow Dash interjects while she comes flapping over on Fluttershy’s other side, “how’s she supposed to see in front of herself if her tits are in front of her like this?”
Indeed, lifting the mare’s breasts might mean that they aren’t resting on the floor anymore, but instead they are now rising up far into her field of view, completely occluding everything with yellow and the pinkish straps of the bra. Fluttershy gapes silently as she looks up at herself, the peak of the dual summits so much higher than her, a perspective that she is not accustomed to seeing.
“She won’t,” Twilight replies plainly, though she’s still looking at Fluttershy when she says this. Fluttershy wilts from her stern gaze but can’t help blushing. “That’s why the enchantment has modular settings. If she needs to be able to move more easily, she can turn it up. If she needs to be able to see, she can turn it down. I’m afraid there’s only so much that can be done at this point; it’s one or the other, she’s just going to have to exercise her best judgment.”
“You don’t have to talk about her like she’s not here,” Rainbow grumbles, arms crossed over her front, each hand clasping tightly at the opposite limb.
Suddenly Rarity comes in to stand beside Twilight and she interjects, “Well thank goodness that it all works properly! Marvelous work on the enchantment, Twilight!” She extends one hand around the alicorn to pull her into a sidelong embrace. She in turn doesn’t respond and does little to react, remaining stiff and stern.
“Yeah, well, I guess that means we’re all done here now,” Rainbow mutters as she reaches to take hold of Fluttershy’s hand. The bustier pegasus feels her heart race as she squeezes back.
Rarity seems disheartened, perhaps hoping that they would stay longer, but Twilight is quick to step in and remark, “I’d might as well teleport you both out. There’s no way we’re fitting her through the door now that she has the bra on.”
“Oh, y-you don’t have to do that, Twilight,” Fluttershy chimes in hurriedly, “I’d hate for you to have to go through so…so much effort just for m-me. I can…t-try doing it myself.” She says this fully aware of the ordeal that it had been to get herself into the building in the first place. A single tit had been too much for even the back door entrance to the boutique, only able to fit through thanks to its pliancy. Fluttershy had had to adopt a sideways position with her breasts pulled to either side of her, squeezed through the doorway one at a time. She can still remember the tightness of the wooden frame squeezing around her flesh. She leans against Rainbow Dash, her thighs rubbing against each other.
“With all due respect, Fluttershy,” Twilight says in a flat, lecturing tone, “there’s no way you’ll be able to get through that door—or most doors for that matter—while you’re wearing that bra, and I don’t feel like going through that rigmarole from before again. It’s a drop in the bucket at this point, so I’d might as well just get you back home.”
Her horn is glowing and magic is beginning to surround Fluttershy and Rainbow Dash before she can object, though there might have been time for her to do so. They have experienced being teleported by Twilight’s magic in the past, but it becomes a different ordeal for Fluttershy. The field of tingling energy has to spread across her entire body to ensure that every part of her is safely encapsulated before the transportation process can complete. The last thing she sees before her awareness of reality pinches in around her is Twilight and Rarity’s faces. They express their concern in different ways. Fluttershy is scarcely conscious of any of this, too distracted by the sensations of her bosom.
There’s a POP in her ears before everything abruptly blips out.
When her senses return to her, though, she can’t exactly tell that anything is different; her sight has turned to her, but she can still only see breasts, leaving her only able to rely upon the feeling under her hooves being replaced with grass. That elicits a stifled grunt from within her and a pang from her loins, her wings shuddering.
“Twilight…” Rainbow grumbles under her breath, shaking her head and clenching her jaw, “she doesn’t have to be such a bitch.”
“Oh Rainbow, don’t say that,” Fluttershy churrs gently, and this time when she leans into the other pegasus it’s to nuzzle against her cheek. “You know that she means well.”
“She still doesn’t have to be a bitch,” Rainbow mutters while reciprocating the gesture, though she has to exert more force not to be pushed over by Fluttershy’s titanic mass. She places one hand upon the yellow mare’s back and the other on one of her breasts, firmly caressing the soft surface.
After a little while, Rainbow separates and turns around, looking about, then she flaps her wings to get up into the air, to look past the barrier of Fluttershy’s bosom. “We’re close to the house,” she announces, extending one arm to point ahead, “it’s just down that way.” Then she comes back down to Fluttershy, points to the control mechanism on her wrist, and asks, “Do you want to like…turn down the setting on this thing so you can see where you’re going?” The question is leading, her tone hopeful.
“No, that’s fine,” she replies without hesitation, holding the device close to herself, as if to protect it, feeling the thrum of magic from within. She looks ahead at the cresting divide of cleavage in front of her, breasts pressed together tightly enough that she can’t see between them, not low enough that she could see through the gap. “I want…um, I should be…trying to get used to this, shouldn’t I?” She puts on a smile.
Rainbow smiles back, though her ears droop just slightly. “Sure, I guess that makes sense,” she admits. “Well…I can probably guide you still, just to make sure you don’t trip over anything.” She proceeds to jog ahead, around the obtrusive bulk of Fluttershy’s chest so that she can be in front of her (silently marveling at the sight of the huge globes looming over her, only the mare’s legs and tail visible jutting from beneath on the other side). After surveying the immediate area, making sure that there are no rocks or roots jutting up from the earth and no stray animals underfoot, she calls out, “Okay, come on!”
So Fluttershy starts forward. She’s amazed; it’s been some time since she was able to move so easily, without being anchored to the ground, without the active assistance of another pony lifting her in some manner. Though the weight is not absent, it no longer feels so burdensome, almost as if gravity is pulling out at an angle rather than straight downward. With careful, delicate steps, she walks, not thinking about what her destination might be as much as the effort necessary to keep herself upright and maintain the rhythm of one hoof in front of the other, like she is a foal all over again.
“You’ve got a downward slope coming up ahead, be careful!” Rainbow calls to her, distant and muffled on the other side of the continental divide between them.
The incline is slight but noticeable, enough that to Fluttershy and her precarious balance it might as well have been a sheer drop. The profound frontal bulk of her chest tugs on her, goading her on. It almost feels to her like she is no longer the one in control, that her breasts are leading her forward and she is merely struggling to keep pace. Something about that is profoundly amusing.
“Hey, everything alright?” the other pegasus’s voice suddenly cries out again.
Fluttershy is about to ask what she means when she realizes that she’s giggling, giddily, madly. She stops in place, just for a moment, reflecting on the clenching in her loins, the faint dampness between her thighs, before continuing. “N-nothing,” she replies, unable to keep from smiling despite herself. “Just…thinking of something funny.” She delicately cups her palm against the surface of one gargantuan globe, feeling the way the surface bobs up and down with every step, pushing back against her. She still giggles occasionally despite her best efforts to stifle the sound the rest of the way back to the house.
The cottage Fluttershy once inhabited had ceased to be adequate for her a long while ago, its doorways and passages far too inadequate to accommodate her swollen bosom. To replace this necessity, Rainbow Dash had brought her own home down from the sky and lashed it to the side of the building; cloud architecture is malleable enough that it can easily be changed without the need for all the costs that would go into remodeling. It had only taken a few days for the two pegasi (Fluttershy hadn’t been so encumbered at the time that it was completely infeasible for her to assist) to convert the cloud-house into a single-story structure with extra-wide doors. Now the cottage itself is largely only used as storage space and Fluttershy can comfortably rest on cushy clouds without having to worry about her inability to fly.
Of course, up until now their design specifications have only had to take width into account, not so much height. While Rainbow opens the door for Fluttershy to enter, she’s unable to get very far before the elevated crests of her breasts brush against the opening’s upper frame. Fortunately, that aforementioned malleability is such that the clouds only bend and warp rather than break, hardly even impeding her entrance in the process. This time, anyway.
“Oops,” she squeaks, looking up at the damage as she passes through. Despite her anxiousness at the inconvenience she has posed in the process, she can’t help feeling some sense of power in her sheer enormity.
“Ah…” Rainbow Dash winces when she takes notice of it. With a few flaps she hovers closer to the top of the frame, and with a gentle touch she presses on the cloud material, massaging it back into its original shape. “No big deal,” she says with an uneasy sigh of relief.
Fluttershy chuckles anxiously back; she can at least be glad that there’s no lasting damage.
But she doesn’t think to stop walking forward, and she isn’t aware that there’s a chair in her way—what would be far away from her actual body, far out of reach of her arms, but her frontal bulk reaches yet further than that—until her bosom crashes into it and sends it falling over. She yelps and jumps as she often does when startled, but nowadays that kind of motion is dangerous, sending a heaving quake through her breasts that nearly sends them smacking right into her own face, throwing off her balance in the process. Her wings snap open reflexively at the sensation that a fall might be upon her, but even with their broad span there would be little done to stop her, not nearly enough. Fortunately, Rainbow is once again quick to intervene, zipping down and coming to brace against her back from behind
“Let’s take things a little more slowly, Flutters…!” she says through clenched teeth. She flaps her wings harder to give herself extra support, but the weight upon her is still crushing.
“S-sorry!” Fluttershy manages to plant her hooves and regain her posture. She still feels her heart beating in her chest, the exhilarating thrill of the moment. It amplifies the heat in her loins. She must stifle a groan fighting to rise up from her throat.
The groan that Rainbow Dash makes is one far more of exasperation as she strolls around Fluttershy and rights the chair. “It’ll take too long for us to play mareco polo through here,” she grumbles, shaking her head as she looks around the living room and the labyrinth of furniture just waiting to get in the way. “I’m just gonna have to lead you by the reins.”
“What do you—o-oh!” The other pegasus’s question is cut short when Rainbow places her hands on her breasts. More specifically, on the central strap that ties the cups of her bra together, knuckles pressing into the pliant flesh in the process. She pulls, leading Fluttershy forward, turning around the obstacles that stand in their way.
“Twist to the right,” she instructs while tugging the huge double-mass to the side, unable to affect a sufficient motion by her own power.
Fluttershy obediently does as told, turning while continuing to follow in the direction that Rainbow directs.
In doing this, though, Rainbow neglects to consider that the turn would bring one of the breasts mashing upon her, its warm embrace washing over her, and she grunts.
“Is everything alright?” Fluttershy asks warily.
“Just fine,” she replies, slightly muffled with her face pressing into the cushy surface. It’s inviting, tempting, but for the moment she has to keep herself composed.
They maneuver together over toward the couch, where Fluttershy is finally able to sit down, gently easing backward. In the past, she would have her breasts spilling out in front of her, an avalanche of butter-furred flesh, their breadth having begun to encroach upon that of the couch as of late, as if forming a whole new piece of furniture attached to her body. Now, however, with her levitating bra still active, the giant mounds are still held up in the air, undersides reaching no lower than her lap, their shape pert and round instead of sagging. They continue to wobble after her landing as she settles into place, and then they bob faintly with the heaving of her chest as she catches her breath.
“There,” Rainbow Dash mutters, surveying her work—a view which mostly consists of boobs. She is panting herself, sweat on her brow, her mane frazzled. She too feels her heart beating in her chest, steady and heavy and eager. She wets her lips before she continues to speak. “You can take the bra off now, or turn the magic down, or…whatever, you know.”
There is a squeak of a noise from Fluttershy on the other side of the great wall which sounds closest to a “Nuh-uh!” of disagreement.
Groaning and crossing her arms, Rainbow replies, “You can’t just wear that thing all the time now, Flutters. I may have said that Twilight’s acting like a bitch but I still trust her with this magic junk, and she wouldn’t have told you you it was important to turn it off sometimes without reason.”
Fluttershy makes another sound, more indistinct in its vocalization. Though these new circumstances make it so that all view of her upper body is obliterated, Rainbow can still see her legs, the way they squirm and fidget anxiously, needfully.
“Alright, fine,” the cyan pegasus mutters under her breath, quickly peeling off her dampened shirt and shorts.
Then she proceeds to step forward and stuff herself into the gap between Fluttershy’s breasts. The demure mare promptly gasps and squirms in her seat. The slightest motion on her part is enough to rock her breasts about, making it harder for Rainbow to wriggle through her cleavage, but nonetheless she persists. Without the bra, it would have been easy for her to wade into the gap; with the way they are now, pressed tightly together, it is a far more cumbersome process, pushing aside handfuls of tit one after another so that she can make a tunnel for herself. It’s far from enough to deter her, if anything only spurring her on further. “This must be what it’s like to be Fluttershy,” she muses to herself in amusement.
Just as the need to breathe becomes apparent, Rainbow’s head peeks out the other side, now even more unkempt, inches away from Fluttershy. The process seems to take an eternity, yet really the distance crossed isn’t so far. Rainbow places her hands on Fluttershy’s shoulders, standing over her, legs straddling hers. From her hips up to her armpits, she is buried within the mountainous mammaries which are between them.
Fluttershy looks up at her in turn, sheepish. Her mouth hangs ajar, tongue lolling out as she breathes in hot and labored gasps. A deep blush discolors the fur on her face and her eyes shimmer with unspoken feelings of lust and desire.
“You just can’t help yourself, can you?” Rainbow Dash whispers to her before she then caresses Fluttershy’s jaw in her palm, gentle yet forceful. She leans in so that their muzzles press together; Rainbow puts in most of the work, lips and tongue playing at her partner, Fluttershy reciprocates as best as she can through her haze of arousal, writhing languidly. A trickle of saliva bridges them for an instant when the lead pegasus pulls away, grinning knowingly. “We went to all this trouble to help you out, and you just find new ways to make life harder on yourself. You’re really committed to your titty lust.”
“I…I loooove…” Fluttershy croons desperately while stretching out her arms and grasping at her bosom, the mass which brings her so much inconvenience and so much joy.
“Yeah?” Rainbow’s smile turns hungry, predatory, as she seizes the back of Fluttershy’s head and holds her steady. “Well why don’t you get a load of these?” She lowers her whole body against the other pegasus, starting with pushing her breasts directly against her face. Rainbow Dash is far from a busty pony, and compared to Fluttershy she is microscopic, the meager handfuls of her chest hardly betraying any meaningful cleavage from her black sports bra. All the same, Fluttershy still dutifully presses her muzzle into the cushy surface, moaning deeply and rocking from side to side. Rainbow bucks against her, eagerly doing as much as she can to smother the pony while the two of them are already buried by a pair of yellow boulders, her crotch grinding on Fluttershy’s stomach. The atmosphere feels muggier around them, hotter steamier, as if in a sauna, raised to a boil by the heat building within their loins.
Fluttershy groans and then places her open mouth directly against Rainbow’s sternum, dragging her teeth through the blue fur, scraping the skin. “I know you’re hungry, girl,” Rainbow mutters through a clenched jaw. She’s already working with one hand to yank down her underwear, her moist vulva quivering at the open air. It takes more work for her to tug on Fluttershy’s shorts and panties, wedged underneath her, the mare too engrossed in their carnal feast to raise her rump enough that this could be easier. She has practice with this, though, so before long the two of them are naked, sans bras; Rainbow knows without asking that Fluttershy still isn’t going to want hers off, so she’d might as well keep hers as well.
The cyan mare lowers herself; Fluttershy seems adrift for a moment without breasts to nuzzle against, and the daze of her lust washes back over her once more. Rainbow Dash would certainly never want to be thought of as slow in any capacity, so she works quickly to contort her legs, twisting them around her partner’s, reducing the space between them. They are nearly flush with each other, stomachs pressed together, Rainbow’s meager bosom pushing through the overflowing yellow mountains to their base at Fluttershy’s chest. Rainbow sees the aroused confusion in Fluttershy’s face as she gasps and whines, right before she lights up with a shrill cry as their vulvas come together, clits touching. She has just a moment to chuckle to herself before a jolt of electrifying stimulation surges up through her own system and then she too is lost.
The two pegasi snap together and embrace, kissing vigorously and squirming and bucking at each other. Fluttershy’s enormous breasts bob all around them, heaving rhythmically, and the way Rainbow’s wings flutter and brush in between them only spurs her to greater heights. They cry and gasp harshly in an incomprehensible song, every other verse muffled as one mare clamps their mouth on the other for another smooch, another taste of their succulent flesh. Rainbow holds tightly to Fluttershy, hands grasping at her back, kneading the musculature and bones underneath the skin, but the only thing Fluttershy can think to reach for in turn is her own bosom, the all-encompassing mounds that are her whole world. Of course, in squeezing them together, she can be said to be holding Rainbow Dash too. Everything she loves, all at once.
They clench together. Rainbow holds a squealing groan in her throat. Fluttershy lets her head fall back and trills a long vibrating note of pleasure louder than any vocalization she would make while casually speaking. Their sticky juices gush and mingle with each other.
Finally they’re able to relax, gasping for breath. Fluttershy slumps back against the couch and Rainbow leans upon her, muzzle prodding at the mare’s neck. Her enchanted bra isn’t enough to completely offset the sheer weight of the breasts which weigh upon both of them.
“Ough…it’s sweaty in here,” Rainbow mutters, weakly squirming in the coffin of flesh that she’s gotten herself entombed within.
“I thought you loved working up a sweat,” Fluttershy says, quiet and sleepy but without a hint of a stutter.
“It’s not the same when it’s another pony’s sweat.” Rainbow brushes aside the frazzled pink curtain of Fluttershy’s mane to look at her face, her dreamy, contented smile, and she smirks back at her. “You don’t mind, now do you? When do you ever get bothered by anything?”
“Let’s see how much I can tolerate, then,” Fluttershy croons back at her, licking her lips.
The couch creaks and rocks beneath them as they embrace anew.
Author's Note
Hyper shenanigans are perhaps pretty typical, but the prompt for this was based around the idea that Fluttershy specifically gets off to how inconvenient being hyper is, which was amusing to me.
What happened to Discord? Who knows.
No lactation, surprisingly.
