Ruby x Blake - Body Morphing

Summary:

Blake goes to her dorm room to get her teammates, who are late for class. A mysterious gas seeps in.

Work Text:

"Come on, guys, we're going to be late for class," Blake Belladonna called out, her voice echoing through the empty dorm hallway. Her roommates, Yang Xiao Long and Weiss Schnee, were nowhere to be found. Typical, she thought, rolling her eyes. She'd be the one to face Professor Ozpin's wrath again.

Blake approached the door to their shared room, her hand reaching for the doorknob. But as she turned it, she discovered to her dismay that it was locked. "Great," she muttered under her breath. "What kind of prank is this?" She stepped back, examining the door for any signs of tampering, but everything looked normal.

Before she could even knock to rouse her roommates, she heard a faint hissing sound followed by a sudden influx of pink gas seeping through the crack at the bottom of the door. She recoiled, eyes widening as the gas grew denser, quickly filling the corridor. "What the...?" she exclaimed, coughing as the gas tickled her nose and throat. It smelled faintly of berries, which she found oddly calming despite the alarm bells ringing in her head.

The pink mist grew thicker, and she could feel it brushing against her ankles, then her calves, and before she knew it, the gas had risen to her knees. Blake felt a peculiar tingling sensation, a warmth spreading up her legs, and she glanced down to find her clothes stretching in an impossible way. Her heart raced as she watched her thighs swell and her butt inflate like a balloon, straining the fabric of her shorts. Panic set in as the gas reached her waist and her stomach began to distend, the pressure building uncomfortably.

Her shirt was the next to go, the material disintegrating before her eyes and revealing her lace bra, which was already struggling to contain her growing assets. The fabric of her shorts followed suit, tearing away as her thighs grew wider, and the elastic waistband snapped. With a gasp, Blake felt the cool air on her bare skin as the shorts fell to the floor, leaving her in nothing but her underwear and a pile of pink, shimmering dust. She looked down at herself, horrified, her hand flying to cover her mouth as her eyes watered from the gas.

Her underwear, too, began to disintegrate. The lace of her bra strained against the expanding flesh of her back, giving way with a soft rip. The cups bulged and then burst open, freeing her breasts to bounce as she tried to maintain balance on her now thick, unsteady legs. She watched in disbelief as the pink fabric of her panties stretched to the breaking point, the elastic snapping with an audible pop. The fabric fluttered to the ground, leaving her fully exposed to the strange, transformative mist.

As the music grew louder, she found herself unable to resist its hypnotic rhythm. Her body began to move on its own accord, hips swaying and popping in a way she had never felt before. It was as if an invisible force had taken over her muscles, making her twerks more exaggerated and sensual than any she had ever seen or done. The sensation was overwhelming, a mix of fear and a strange, exhilarating pleasure that she couldn't ignore.

Her ass bounced and jiggled in time with the beat, growing larger with each movement. The pressure grew intense as her cheeks ballooned outward, stretching her skin to its limits. She could feel the heat from within as the gas continued to work its magic on her body. Each twerks sent a shockwave of pleasure through her, making her moan despite her efforts to remain silent. The sight of her reflection in a nearby window was surreal; she looked like a caricature of herself, her proportions impossibly exaggerated.

Blake's eyes widened as she felt herself getting shorter, her feet lifting off the ground. She grabbed onto the doorframe for support, her once-normal height now lost to the relentless growth of her lower body. The gas had a mind of its own, sculpting her into something new, something that defied all logic. Her legs, now thick tree trunks, trembled with the effort of supporting her massive weight. Her knees bent slightly, adapting to the new distribution of her body mass.

The sensation was disorienting, as if she was shrinking from the waist down while her torso remained the same. The pressure on her back grew unbearable as her buttocks swelled, pushing her spine into a dramatic arch that sent waves of pain and pleasure through her body. She stifled a cry, not wanting to give in to the transformation's allure. Yet, the music's tempo grew faster, and so did her twerks, her body moving in a mesmerizing dance of submission.

With a sudden burst of willpower, Blake forced herself to stop twerking and took a deep, painful breath, the fabric of her shredded bra barely containing the inflating orbs of her breasts. Her nipples stiffened with anticipation as she tried to regain control over her body. The pink gas, seemingly responsive to her change in movement, shifted its focus. The beat of the music grew more intense, and she felt a new command in the rhythm—bunny jumps.

Her legs, now thick and powerful, propelled her into the air. Each jump sent her breasts bouncing in a way she never thought possible, and she watched in amazement as they grew larger with every leap. The fabric of her bra stretched beyond belief, the lace unraveling and falling away to reveal her swollen, pink-tinged flesh. The weight of her breasts grew uncomfortable, but she couldn't fight the gas's power. It was as if her body had become an instrument to the music, her actions dictated by the pulsing beat.

Her jumps grew higher, her breasts swaying in time with her movements. The pressure grew more intense, and she could feel her chest swelling to accommodate her growing assets. The pink mist swirled around her, caressing her skin with its warm embrace, making her feel both exposed and oddly powerful. The corridor was now filled with the sound of her flesh slapping against itself, a symphony of bouncing flesh that echoed through the empty halls.

And then, without warning, the music stopped. The sudden silence was deafening, the absence of the beat like a punch to the gut. The gas lost its rhythm, its energy dissipating as the last notes of the mysterious melody faded away. Blake's legs, which had been moving of their own accord, stilled mid-air. For a moment, she hovered, the gravity of the situation hitting her harder than the abrupt end of her involuntary dance.

Her eyes searched the corridor, desperate for any clue as to what was happening. The gas thinned and retreated, leaving her in a cloud of shimmering pink dust. Slowly, she floated back down to the ground, her newfound weight causing the floorboards to groan under the pressure of her inflated form. She looked down at herself, the sight of her swollen body a stark contrast to the stark reality of her predicament.

The windows along the hallway suddenly sealed shut, the glass darkening to prevent any light from escaping. The air grew thick with anticipation, the silence broken only by the sound of her own breathing, now heavy and labored. The pink gas rushed back into the room, filling the space around her with renewed vigor. It coiled around her like a serpent, wrapping her in a warm embrace that was both comforting and terrifying.

Her eyes widened as she felt a peculiar sensation at the base of her spine. Something was growing, pushing against her skin. She reached back, her hand coming into contact with a soft, furry appendage. "A tail?" she murmured, incredulous. The realization hit her like a ton of bricks—the gas wasn't just inflating her body, it was altering her in ways she hadn't even considered. The tail grew longer, brushing against her inflated thighs as it swished from side to side. It was covered in sleek, black fur that matched the color of her hair, and it twitched with every beat of her racing heart.

Then, she felt a pinching at the top of her head. She tentatively raised her hand to her forehead and felt the unmistakable presence of two small, pointed tips poking through her hair. Cat ears! They grew longer and more pronounced with every passing second, standing at attention like antennae tuned to some unheard frequency. The sensation was strange, but she couldn't help but feel a twinge of excitement. Despite the horror of her situation, there was something undeniably thrilling about this newfound feline aspect to her body.

But the transformation wasn't over yet. As her ass continued to grow, so too did her lips, inflating to an obscene size. They plumped and stretched, taking on a glossy sheen that made them look perpetually wet. It was as if her mouth was begging to be filled, to devour something whole. She tried to speak, but her words came out as muffled, incoherent sounds, her mouth now too large to form coherent syllables. The effort was futile; she was now more pantomime than conversation, her thoughts trapped behind a pair of balloon-like lips.

The heat grew more intense, and she felt her pussy swelling in time with her lips. It was as if she was being turned into a living, breathing sex doll, her body sculpted by the whims of some invisible artist. Her labia grew thick and puffy, the skin stretching taut around her clit, which now protruded like a tiny button begging to be pushed. The gas had worked its way into her most intimate areas, leaving her no escape from its all-encompassing influence.

Her vagina began to pulse in sync with the beat that had once filled the air, the walls expanding and contracting with a mind of their own. The sensation was unbearable, and she could feel the wetness pooling between her legs, leaving a shimmering trail on the floor below. Her pussy was now a gaping maw, the folds inflating until she looked as if she was wearing a pair of pink, glistening panties made of flesh. The constant dripping was maddening, each drop a sweet torment that only served to fuel her arousal.

The itch in her anus grew more persistent, the sensation of fullness spreading from her swollen pussy to her tight, puckered hole. Her cheeks clenched involuntarily, as if trying to hold back an unseen force, but she knew it was futile. The gas had taken control of her, reshaping her body to some unknown end. The thought of being filled there, of feeling a cock stretch her wide, sent a jolt of desire through her that was impossible to ignore. Her hand hovered over the entrance, the pad of her finger brushing lightly against the sensitive skin, and she couldn't help but wonder what it would be like.

As if on cue, the door to the room burst open and a figure stumbled out, their eyes glazed over and their mouth hanging open in a perpetual O of shock. It was Ruby, her uniform torn to shreds and her body transformed beyond recognition. Her once athletic form was now an exaggerated caricature of feminine proportions, her chest and ass swollen to impossible sizes. But there was something else, something that made Blake's stomach flip—a thick, veiny cock bobbed between Ruby's legs, the pink tip leaking precum.

The scent of Ruby's arousal hit Blake like a physical blow. It was a heady, musky scent that seemed to fill the corridor, making it difficult to think of anything else. Her nose twitched as she took in the aroma, and she felt a strange, primal urge to get closer, to explore this new aspect of her friend's body. Her eyes went blank, the only thought in her mind the need to feel that cock against her own inflated flesh.

Her body, now a pink, glistening monument to the gas's power, turned to face Ruby. Her legs wobbled as she took a step closer, her inflated ass swaying hypnotically with the motion. The pressure in her anus grew stronger, and she could feel her sphincter stretching, the skin puffing out to form a perfect donut shape. The transformation was complete, and she knew what was expected of her.

Ruby looked at her with wide, unseeing eyes, their gaze locked on Blake's inflated body. The pink-haired girl was just as lost to the gas's power, her hand unconsciously stroking her newfound cock. Blake licked her swollen lips, the urge to feel that thick shaft inside her overwhelming. She took another step, the sound of her flesh slapping against the floor echoing through the hall.

Standing at her full, transformed height, Blake was now at crotch level with Ruby. She leaned in, her massive breasts jostling with the movement, and wrapped her mouth around the tip of Ruby's cock. The sensation was unlike anything she had ever felt before—the warmth, the velvety softness of the skin, the faint taste of sweetness that seemed to emanate from it. She moaned around it, the sound muffled by the sheer size of the organ filling her mouth.

Ruby's eyes rolled back in her head as she felt the heat of Blake's mouth envelop her cock. Her hand, still wrapped around the base, began to move in tandem with Blake's bobbing head. The gas had taken away their ability to speak, but it had also amplified their senses. Every touch, every sensation, was magnified a hundredfold.

Blake's jaws stretched to accommodate Ruby's thick length, her cheeks hollowing as she took more and more of her into her mouth. The feeling of power was intoxicating, the sense of control she had over Ruby's pleasure a heady aphrodisiac. She could feel the veins pulsing against her tongue, the precum leaking onto her taste buds and sending shockwaves of arousal through her inflated body.

But suddenly, Ruby's eyes snapped back into focus, and she ripped Blake off her cock with a feral growl. The sound was so unexpected, so raw, that Blake's knees buckled. She stumbled backward, her ass bouncing with the momentum, leaving a trail of wetness on the floor. Before she could recover, Ruby had her by the waist, hoisting her up into the air as if she weighed nothing. The sudden change in position made her breasts jiggle and bob, the sensation sending a fresh wave of pleasure through her body.

And then, she saw it. Another cock grew from Ruby's groin, identical to the first in every way, except for the fact that it was now nestled between her massive, inflated thighs. It stood tall and proud, pulsing with the same need that Blake felt in her own body. Her eyes widened in shock, her mouth forming a perfect "O" to match Ruby's earlier expression. The gas had not just transformed them, it had duplicated Ruby's most sensitive part, creating a mirror image of lust and desire.

With a grunt, Ruby bent her knees, lowering her cocks to Blake's level. Her eyes never left Blake's, a silent challenge that sent a thrill of fear and excitement down the latter's spine. Without a word, Ruby flipped Blake over, her massive breasts and ass bouncing in a way that was both mesmerizing and terrifying. The pink haired girl's breath was hot against her ear as she whispered, "You know what to do," before pushing one of her own cocks into Blake's waiting anus.

Blake's eyes watered as the thick, veiny shaft penetrated her, stretching her to the limits of what she thought possible. The sensation was indescribable, a mix of pain and pleasure that sent her over the edge. Her body was a canvas for Ruby's desires, and she could feel the gas urging her to accept it all. The second cock hovered over her pussy, the precum glistening in the dim light of the corridor. With a grunt, Ruby pushed it in, filling Blake completely. She could feel the pressure building, her walls stretching to accommodate the impossible girth.

The two of them moved in a rhythm dictated by the gas, their bodies sliding against each other with a wet, suction-like sound. The floorboards creaked under the weight of their exaggerated forms, the sound a symphony of flesh against flesh. Blake's ass cheeks clapped together with every thrust, the sound echoing through the hallway like a drumbeat that matched the pulse of the pink gas that still swirled around them. Her eyes rolled back in her head as Ruby began to piston in and out of her, the motion sending waves of pleasure through her inflated body.

But as the intensity grew, Blake felt something peculiar happening to her legs. They began to shrink, the muscles and bones seeming to dissolve into the pink mist that still clung to their skin. She tried to kick, to push back against Ruby, but there was nothing to move. Her legs had all but disappeared, leaving her in a state of floating suspension, supported only by Ruby's powerful arms and the cocks that filled her.

Her thoughts grew fuzzy as Ruby's pace increased, the pressure on her G-spot unbearable. Her massive breasts swayed in time with the rhythm of their bodies, the weight of them now a constant source of pain and pleasure. Each thrust sent a jolt of electricity through her, making her back arch and her inflated lips quiver.

And then she felt it—another set of hands. They seemed to appear out of thin air, wrapping around her swollen breasts with a gentle yet firm grip. The sensation was so sudden, so unexpected, that she couldn't help but let out a muffled cry. The hands were Ruby's, a second pair that had emerged from her back, their skin a shimmering pink to match the transformation gas that surrounded them. The sight was bizarre, yet the feeling was utterly divine.

Ruby's new arms moved with a grace that belied their sudden existence, her hands cupping and squeezing Blake's breasts with an expert touch. Thumbs flicked and teased at her sensitive nipples, sending sparks of pleasure that shot straight to her clit. Blake's body was now a playground for Ruby's desires, her mind a haze of need and confusion. The pink mist swirled around them, caressing their flesh as if it were a living entity, egging them on to explore each other further.

With a grunt of effort, Ruby backed into the room, still impaling Blake on her cocks. The door swung shut behind them, cutting off the view of the corridor. The room itself was a wreck, the bed in the center a tangled mess of sheets and pillows. The scent of sex and the gas hung heavy in the air, a heady mix that seemed to intensify the sensations coursing through Blake's body.

As Ruby's thrusts grew more frantic, Blake's eyes fell upon a glass of pink milk sitting innocently on the counter. Her mind, addled by the gas and the overwhelming pleasure, fixated on it. It called to her, a silent promise of relief or perhaps a new twist to their transformation. Without thinking, Ruby's free hand reached for the glass, the liquid within sloshing with each of their movements.

Her hand trembled as she brought it to her lips, the cold glass a stark contrast to the heat of her skin. She took a tentative sip, the sweet, creamy liquid coating her mouth. It tasted like berries and something else, something she couldn't quite put her finger on. As the drink touched her tongue, she felt a strange tingling sensation, not unlike the gas that had transformed her.

With growing curiosity, Ruby drained the glass, the pink liquid sliding down her throat in a smooth, velvety wave. Almost immediately, she felt a new sensation growing between her legs, a heavy weight that was both strange and oddly familiar. Looking down, she gasped as a pair of testicles began to form, swelling and descending from the base of her cocks.

They grew larger and larger, the skin stretching taut, until they were the size of basketballs. The weight of them was astonishing, each one hanging low and full, bouncing with every movement. The transformation was unlike anything she had ever experienced, and she couldn't help but be both terrified and fascinated. Her eyes grew wide with each passing second as they inflated further, her body adapting to accommodate the new additions.

The pink gas grew denser, wrapping around them like a warm blanket, urging them to continue their depraved dance. Blake felt a hand on her ass, but when she looked back, she saw it was Ruby's, her extra arm reaching around to cup and squeeze the massive cheeks. The sensation was too much, and she could feel her orgasm building, the tension in her body reaching a fever pitch.

The room was spinning, the walls seeming to pulse in time with the beat of their bodies. The pink mist grew thicker, coating everything in a fine layer of shimmering dust. Blake's thoughts were a jumble of pleasure and fear, her body a playground for the gas's whims. But she couldn't deny the thrill of it all, the way her body responded to Ruby's touch, the way she craved the feeling of being filled.

As Ruby's new cock grew, so too did the intensity of her thrusts. Each penetration was deeper, more demanding, the thick shafts stretching her further than she ever thought possible. The sound of their bodies colliding grew louder, the slap of skin echoing through the room like a drumbeat that matched the pounding in her chest. She could feel her orgasm approaching, a tidal wave of sensation that threatened to consume her.

And then it hit—a crescendo of pleasure so intense that it blotted out everything else. As Ruby came, Blake's belly inflated to the size of a yoga ball, the skin stretching taut and shimmering with the pink of the transformation gas. Her eyes rolled back in her head, and she let out a guttural moan that seemed to resonate in her very soul. The sensation was overwhelming, a pressure that seemed to fill her entire being, leaving no room for thought or anything but pure, unbridled ecstasy.

The gas grew denser, the pressure in the room seeming to build with every beat of their hearts. The pink mist swirled around them, coating their bodies in a fine layer of shimmering dust that clung to their sweat-slicked skin. The transformation was far from over, it seemed, as the room around them began to morph, the walls stretching and bulging as if made of the same pliable substance as their bodies.

With a final, powerful thrust, Ruby's new cock exploded within Blake, sending a warm, sticky spurt of fluid into her already stretched pussy. The force of the orgasm made her body convulse, her inflated form jiggling and bouncing with the intensity of the climax. The gas responded to their shared pleasure, pulsing with a new energy that seemed to flow into their very cores, amplifying their sensations to new, uncharted heights.

As they both panted, trying to catch their breath, Blake felt her swollen belly begin to shrink back to its normal size. The pink of the gas bled away, leaving her skin soft and sensitive. But the transformation wasn't quite finished. Her breasts, still massive and heavy, began to tingle with a new sensation. They grew even larger, the skin stretching until it was almost translucent, revealing the veins beneath. And then, with a suddenness that took her breath away, her nipples grew hard, pointing upwards like two pink peaks.

Ruby stumbled back, her legs trembling from the exertion, her eyes never leaving Blake's body. The gas had worked its magic once more, and Blake could feel her chest filling with something warm and thick. She looked down to see her breasts swelling even more, the skin stretching until it was taut and shiny. The pressure grew until she thought she might burst, and then she felt the first droplet of pink milk seep from her nipple.

With surprising dexterity, one of Ruby's new pink hands reached around and plucked at the taut peak of one of her breasts. Blake watched, transfixed, as Ruby's eyes lit up with hunger. The pink-haired girl leaned in, her mouth opening wide to engulf the swollen nipple. The sensation was unlike anything she had ever felt—the heat of Ruby's mouth, the suction that seemed to pull at her very soul. It was as if Ruby was drinking from a fountain of pure desire, and Blake could do nothing but let the sensation wash over her.

Ruby's suckling grew more intense, her cheeks hollowing as she drew on Blake's milk-filled breasts. The pink liquid spurted into her mouth, the taste a heady mix of sweetness and something indescribable. It seemed to fuel her, her muscles bulging and her skin stretching even further. The cocks inside Blake grew more rigid, the veins standing out like cords of pure need. Her body was a canvas of transformation, painted in the hues of the gas and brought to life by Ruby's touch.

And then, the unthinkable happened. Ruby's own breasts began to swell, the fabric of her shredded shirt straining until it gave way entirely. Her nipples grew darker, the areolas expanding into large, round circles that puckered and pointed. The same pink fluid that filled Blake's breasts began to fill hers, the pressure building until she could feel it in every fiber of her being.

With a grunt, Ruby lifted Blake higher, her newfound ass muscles flexing with the effort. The room was now thick with the gas, the air itself seeming to pulse with energy. Blake's eyes went wide as she watched Ruby's transformation unfold before her, the same power that had reshaped her now sculpting her friend's body into something new. The pink liquid flowed from her own nipples, creating a stream that Ruby eagerly lapped up, her tongue flicking out like a serpent's to catch every drop.

As Ruby drank, her ass ballooned even more, the cheeks swelling to the size of beach balls. The transformation was surreal, her legs thickening and curving to support the massive weight. The pressure of her swollen breasts against Ruby's chest was intense, the sensation of being so completely dominated by another's desires both terrifying and thrilling. Yet, with each gulp of the pink milk, she could feel a strange power coursing through her veins, her own body responding to the gas in new and unexpected ways.

Suddenly, Ruby pulled away, her mouth popping off Blake's nipple with an audible sound. Her eyes were wide, the pupils dilated with a mix of fear and arousal. Blake's breasts continued to leak the sweet fluid, the stream of pink milk pooling on the floor beneath her. The gas swirled around them, seemingly agitated by the sudden change in their interaction. Ruby looked at her own chest, her new cocks still buried deep inside Blake, and she took a shaky breath.

With a sound that was half gasp, half growl, Ruby's body began to shift again. The pink mist coalesced around her shoulders, thickening and forming into a third set of arms. The transformation was quick and painless, the limbs unfurling like petals on a particularly blooming flower. Each hand was as delicate and nimble as the first set, the skin shimmering with the same iridescence. They reached out, one set to continue to play with her swollen nipples, the other to explore the new landscape of her bulging ass.

Blake, however, felt a sudden lightness in her shoulders, and when she tried to move her arms, she found that they were no longer there. In their place was a smooth, curving expanse of flesh that flowed into her inflated torso. She looked down, her eyes wide with shock and confusion, watching as the pink mist seemed to absorb her limbs into her body. Panic set in for a brief moment, but the gas's influence washed it away, leaving only a heightened sense of arousal at the thought of being so utterly helpless in Ruby's powerful embrace.

Her tail, now fully grown and covered in the same black fur that adorned her new ears, began to twitch of its own accord. It grew longer and thicker, the tip curling upwards as if seeking attention. Without any conscious thought, it began to wrap around Ruby's waist, looping around her like a belt made of living flesh. The sensation was strange, but the more it tightened, the more Blake found herself craving the feeling of being bound to Ruby, of being one with the pink-haired girl's body.

Ruby's new arms didn't miss a beat, continuing their ministrations on Blake's breasts as her eyes grew even wider with each twitch of the tail. She reached up with one of her pink hands, touching the fur with a sense of wonder that was quickly overtaken by desire. The sensation was like nothing she had ever felt—warm, soft, and alive, it seemed to purr against her skin. The gas had made them both so sensitive that even the slightest touch was a symphony of pleasure.

The room was a blur of pink and black, the gas's influence pulsing in time with their ragged breaths. Ruby's body was now a masterpiece of exaggeration, her tits bouncing and leaking pink milk with every movement. The sight of Blake's arms merging into her torso was like watching a sculptor at work, the gas molding them into a new form that was both terrifying and exhilarating.

Blake's eyes rolled back in her head as Ruby's new pink hands explored her body. The sensations were overwhelming—the gentle caress of fur against her skin, the roughness of Ruby's new cocks stretching her, the suckling at her nipples that seemed to pull the very essence from her soul. The tail tightened around Ruby's waist, the fur tickling her stomach as it moved, sending shivers down her spine.

But then, with a sudden jerk, Ruby's head snapped up, her eyes focusing on Blake with a wild intensity. She stopped suckling, the sudden absence of her friend's mouth leaving her breasts feeling cold and empty. The pink hands paused in their movements, hovering over her swollen flesh as if unsure of what to do next. The gas around them grew denser, the pressure building until it was almost tangible.

And then, with a sound like a rubber band snapping, Blake's head twisted a full 180 degrees on her neck. Her eyes locked onto Ruby's, and the pink haired girl gasped in surprise. The transformation was so sudden, so extreme, that for a moment, they both just stared at each other, frozen in shock. The gas swirled around them, seemingly eager for the next act in their twisted play.

And then, as if drawn by some unseen force, their lips met. The kiss was like nothing either of them had ever experienced—hot, wet, and desperate. Ruby's extra arms wrapped around Blake's inflated torso, her new cocks still buried deep inside her as their tongues danced together. The pink mist clung to them, seemingly urging them on as their bodies grew more and more intertwined.

But it wasn't enough. The gas had made them crave more, and so their tongues began to stretch, growing longer and more pliable with every passing second. They wove together like serpents, each one wrapping around the other in a sensual embrace that seemed to defy the very laws of nature. The tip of Blake's tongue brushed against the back of Ruby's throat, making the latter moan with pleasure. It was an intimacy that went beyond anything physical, a connection that seemed to speak to their very souls.

Ruby's hips began to move again, her thick cocks sliding in and out of Blake's willing body. The motion was slow at first, almost gentle, but it grew in intensity until it matched the fervor of their kiss. The pink haired girl's tail swished behind her, the tip brushing against the wall with a wet sound that seemed to echo through the room. Each thrust sent waves of pleasure through both of them, their bodies now so attuned to one another that they moved as one.

The transformation wasn't just physical—it was spiritual as well. The gas had bound them together in a way that transcended friendship, that went beyond mere attraction. They were two beings, joined in a dance that was at once ancient and utterly new, their desires melding into something primal and unstoppable.

As Blake's tail split, the sensation was like a jolt of lightning down her spine. The pain was brief, replaced almost immediately by a sense of fullness as the two new appendages grew from the base. They grew longer, thicker, the same shade of black as her fur. The tip of each was as sensitive as her clit, the skin stretched taut over the hardness beneath. They twitched, seemingly alive and hungry for contact.

Ruby, her eyes still locked on Blake's, felt a sudden pressure against her own ass and pussy. She looked down in amazement as the two new cocks pushed against her, seeking entry. Without hesitation, she shifted her hips, the head of one cock sliding into her already filled ass, the other into her wet pussy. The feeling was indescribable—fullness unlike anything she had ever experienced. Her eyes rolled back in her head as she moaned, the sound a mix of shock and pure, unbridled pleasure.

Blake's new tails twitched and grew even more sensitive as they felt Ruby's skin against them. They slithered around her, one wrapping around Ruby's neck, the other finding its way between her legs. The tip of the tail teased her clit, moving in time with the rhythm of their joined bodies. Ruby's hips bucked, the new cocks inside her moving with a will of their own, as if eager to claim her fully.

The pink gas grew thicker, the room spinning in a haze of lust and confusion. Blake could feel her body changing again, her skin rippling and stretching. Her pussy grew wetter, her clit swelling to a size that was almost painful. The gas whispered in her ear, a seductive siren's call that urged her to give in to the pleasure, to let it consume her completely.

Her new tails tightened around Ruby, one coiling around her neck, the other sliding down to tease her clit. Ruby gasped, her eyes widening as the sensation of being claimed so fully washed over her. The tails were like living things, moving with a mind of their own, exploring every inch of her body.

The pink mist grew denser, the air thick with the scent of desire and transformation. The room was a kaleidoscope of color and sensation, the walls seeming to pulse with the beat of their joined bodies. The pink light reflected off Ruby's sweat-slicked skin, casting an eerie glow over the scene.

Blake's tails grew more insistent, one tightening around Ruby's neck like a collar, the other plunging deep into her pussy alongside the cocks. The feeling of being so completely filled sent Ruby over the edge, her body convulsing in an explosion of pleasure that seemed to shake the very foundations of the room. Her cocks grew even thicker, the veins standing out in stark relief as she came, her pink milk mixing with the juices that coated Blake's inner walls.

The gas responded to their shared climax, swirling around them like a tornado of pink lust. Blake's body convulsed, her tails moving faster and faster, the sensation of Ruby's pussy tightening around her driving her to new heights of ecstasy. Her own orgasm built, the pressure in her breasts growing until she could feel it in her fingertips—or where her fingertips used to be.

And then it hit them, a wave of pleasure so intense that it seemed to wash away everything else. Their bellies swelled to massive proportions, the skin stretching until it was paper-thin. They were both so filled with the gas's essence that they could feel it pulsing in time with their hearts, a symphony of transformation that seemed to resonate through the very air around them.

As they came down from the peak of their shared ecstasy, their bodies began to relax. The cocks that had been so rigid and demanding grew soft, slipping out of their tight embraces with a wet sound that was almost a disappointment. The gas grew calmer, the pressure in the room dropping to a gentle caress against their over-sensitized skin. With a final, exhausted gasp, they both collapsed onto the bed, the mattress groaning beneath their combined weight.
