1) Adagio Takes Command

Author's Note

For those of you who read my last story, there seemed to be some confusion regarding the pronouns appropriate for someone with both a penis and vagina. But naturally, gender and pronouns are decided by the person, not their body. For example, Adagio will keep using "she/her/hers" pronouns throughout this story due to identifying as female.

But for all of you celebrating that I don't head-canon Adagio as using singular "they/them" pronouns, you've got a big storm coming in the Aria chapter :3

1) Adagio Takes Command

Adagio was exhausted as she stumbled into her bleak bedroom. The harsh white glare of the fluorescents stung her eyes while her dissatisfied gaze swung over the concrete floors, sparse furniture, and dingy walls. Grumbling to herself, Adagio reflected on the past nine years that had dragged her and the other Dazzlings into this plight.

After their defeat at the hands of those loathsome Rainbooms, the Dazzlings had lost their jewels and nearly all of their powers. The siren’s oldest weapon still remained to them, but sex could only pay for so much. The three noble, ancient creatures had been reduced to working odd jobs and long hours simply to eke out a dull existence. But most jarring of all was the loss of their agelessness. Already, each Dazzling was physically comparable to a human of 25, although their minds were nearly as many centuries old.

Adagio’s leaden feet plodded her into her bedroom, but as she passed her desk, her weary mind suddenly perked up. Looking down at the object centered on the messy tabletop, Adagio remembered the triumph that her tedious job had ripped her away from. For years, she had toiled to collect, organize, and reassemble the three gems the Dazzlings had lost at that fateful concert. After nearly a decade of struggling, she had never managed to complete even a single necklace from her collection of splinters and fragments. Until last night. Now, at long last, the pieces of one ruby puzzle had fallen into place, and a warped and cracked facsimile of her old talisman sat twinkling before her.

But would it work? Adagio had no way of knowing for sure. Well, save for the obvious. Taking hold of her old choker, unworn since the gem’s destruction, Adagio lifted the revived stone to her neck with a confidence she had nearly forgotten. She took a deep breath, and began to sing. But the screeching peal of her ruined voice was all that greeted her. No magic. No power. Useless.

Completely devastated, Adagio turned and stormed to the bathroom aside her room, desperate to drown her sorrows with a tepid shower. When the water was flowing over her face, she let a few tears roll innocuously into the stream. This was the only place she ever cried, because here among the concealing water she could deny her weakness, even to herself.

Forcing herself to numbness, Adagio focused on the minutia of washing her body in order to dull the pain of loss and regret. This ritual of self-pity had become familiar, even as her body had become increasingly foreign, changed by aged and maturation. Much of the form she had known for so many centuries still endured, but much had changed as well. She had grown taller, for one thing, standing at an imposing 5’ 11”. Although the grandiose effect of her presence had been diminished with the loss of her voluminous hair. After a baby-sitting gig had turned into a chewing gum fiasco, she had been forced into a mere bob-cut, which now hung in short, wet tendrils around her face. As she shampooed her diminished locks, a rivulet of suds snaked down her plain breasts. Her shapely b-cups, each peaked by a small, dark nipple, had not developed much from their original size. Her lower body had fared better, with curving hips and pert posterior swelling to 35 inches in total circumference. As Adagio soaped her body, her hands rested for a brief instant on her ass, feeling the smooth, yellow skin atop toned muscle that shaped her buttocks into pleasing spheres.

When Adagio finally exited the shower, she felt somewhat refreshed, though still morose with her many setbacks. As she dried her face and neck, she felt the pendant still hanging from her throat. She had worn it the whole time without thinking, falling so naturally into her old habits of never parting with her old source of power. Stepping out of the humid bathroom into the brisk air of her bedroom, Adagio wandered to the cracked, full-length mirror that was her only wall decoration. She studied herself in the glass, trying to see the great and powerful siren she had been for so many centuries. But what she saw was only a pale shadow of the glory she remembered: an aging face, a mutilated mane, and now a cracked gemstone hanging impotently from her collar. The site made Adagio sick, and she almost longed for another shower to wash away the image in front of her. Grabbing a lock of her hair, she vented one part of her frustrations.

“Just grow already!” she snapped fiercely.

Suddenly, she felt her gem stirring into an echo of its old vibrance. Thin, green smoke trailed from the craggy stone, rising up to circle around her head like a sickly halo. In the mirror, Adagio could see her hair rapidly growing, curling and lengthening as it spread down her back. In just a few moments it had reached its old size, stretching all the way past her rear and spreading out to either side twice the width of her body.

Adagio brimmed with elation as she palmed handfuls of her copious curls, delighted to not only regain her hair, but apparently some of her long absent power. If she could control even just her own body…oh, the things she might do. That thought set her mind into devious motion, and she paused. Oh, the things she might do, indeed. Her attention had turned to Sonata and Aria, her bandmates, minions, and lovers. A lecherous smile curled Adagio’s thin lips as she finalized her plans for her loyal pets. But first, she would need some supplies. Hopefully her new powers were up to the task.

“I need a cock,” she demanded dryly, slipping naturally into the air of command that had activated her old magic. The new magic responded obediently, sending out green clouds to swirl and twist their way down her body. A maelstrom of green smoke and light formed a cylinder around her crotch, before melting away to reveal a golden penis and balls blossoming from her former clit.

Taking the soft tube in one hand, Adagio’s thoughts poured over all of the wonderful ways she might use this living strap-on to torment and titillate her two other play things. She was suddenly pulled from her reverie by a queer sensation in her new appendage. The saffron shaft seemed to be changing, sliding out along Adagio’s palm as it pulsed and throbbed longer and thicker. Adagio was enthralled by this development, growing ever more enticed as she watched the oddly erotic display of her new tool engorging itself. Pulling back lightly on the foreskin, a dark, flared head popped free to cap off her 6 inches of girthy dick. Adagio breathed in deeply, savoring the sweet shiver of delight that ran up her spine as her delicate tip was exposed to the bedroom air. At the same time, faint hints of pleasure played out under the pressure of her gently grasping fingers.

As usual, Adagio was quite pleased to get what she had wanted. And while this conceit towards masculinity certainly didn’t reflect on her style or identity, the way such things did for Aria, it would still make a wonderful addition to her arsenal of nefarious toys. Smirking wickedly, Adagio stroked her new plaything, sending shivers up her spine and shaky breaths escaping her lips. She didn’t like to lose composure like that, but she had few other complaints about how the evening was developing. That was, except for the size of her new package. The egregiously ordinary size of her penis ranked it among the smallest of her artificial tools. But she had just discovered the panacea to all such bodily woes, and she intended to use it generously.

Gripping tightly around the center of her turgid pole, fingers sinking into the soft foreskin, Adagio growled deeply, “grow.” Her magic flared to life immediately, and another puff of green smoke accompanied an overwhelming jolt of arousal. Adagio’s head was sent swimming and her vision blurred as the magic enveloped her. The glug glug or surging blood and streeetch of expanding skin filled the room as Adagio’s cock wriggled forward. The tightness along her member mounted even higher as firm tissue swelled outward. “Ungh,” she grunted with tight shut eyes and an opened mouth as her cock settled in to its 8 inch size. Its two inch diameter filled her hand with hot, stiff meat. Grabbing her thicker shaft with both hands, Adagio pulled gently on the foreskin to expose more and more moist, sensitive cock, the whole thing raging with swollen blood vessels and a ruddy hue that revealed her acute arousal.

Adagio was not satisfied at all with that pitiful display, though it suggested such great potential. This latest pet of hers would simply have to learn her tastes, and how to obey them properly. Grabbing her cock roughly just below the head, she spat through clenched teeth, “Grow more!” Dutifully, her head surged forward another inch, and it didn’t stop there. The elastic sound of her developing skin and tissue returned with gusto, and Adagio could feel the swift flow of blood into her swelling cock. Unconsciously, her toes curled, her legs tensed, and her fingers dug more tightly into her expanding dick. Pulling one hand free from her shaft, she clasped the head of her sensitive cock, gauging its progress. But in no time her broad tip pushed and slid past her fingers, smearing pre with its steady forward passage. Adagio let out pleasured gasps as her growth continued to intensify her lust and excitement. “Ooooh,” she finally breathed, as a near orgasmic spurt of size left her at a steady 14 inches long, and some 3 and a quarter inches thick.

Her massive cock continued to throb gently in her hands, its tremendous heat burning against her pre-cum slickened palms. Stumbling two steps to the bedroom wall, Adagio let her back slump against the hard surface, steadying her on her sex-weakened legs. But she had not had her fill just yet. This cock seemed to be a slow learner, so she made her displeasure plain. “You stupid thing. I said more! Bigger!” she snapped. Another flash of green vapor poured into the room. Pulsing violently with its expansion, her dick rocketed forward. Her thickening girth and swelling balls pulled with ever greater weight on her pelvis. By far this was the most erotic growth yet, causing Adagio’s grunts and moans to mingle with the clamorous stretching of her skin. Adagio snatched up her burgeoning member with both palms and heaved it vertical, pouring up and down its length with firmly gripping hands. Adagio was on the very brink of orgasm, but suspended there seemingly without end. Her hands could barely close around her massive shaft, even together, as it soared to the level of her collar bone and began to slow. Already 2 feet long and more than 5 inches across, her dick was an inhuman behemoth, but that was still not enough for an inhuman siren such as herself.

Before the growth sputtered out completely, Adagio roared, “No, more! I said more!” Finally, that seemed to do the trick. Her cock absolutely exploded, bursting out of her grip as her hands flew away in shock. Gobs of pre rained down on her cock and chest as they were spurted upward. The liquid continued to plaster a forward-stretching line along her floor as her mammoth pole fell forward under its still mounting weight. The pop and slither of developing flesh drowned out Adagio’s thoughts as her cock bounced upward with each uneven throb of growth. Her balls bulged with growing reservoirs of cum, each sphere already the size of a softball and still swelling along with her fat cock. Her growth seemed to stretch on endlessly, inch after inch of fresh hard cock protruding from her retracted foreskin. Adagio returned her hands to supporting her dense rod, but its own diamond hardness kept it jutting straight out from her pelvis. She continued to edge the very precipice of her coming orgasm as her dick finished more than a foot of growth, ending at 3 foot 2, and seven and a half inches from side to side, significantly more than even both of her hands could enclose.

Adagio’s nostrils were filled with the unique scent of her moist cock and the salty tinge of pre pooling on her floor, both mingling into an erotic musk that pleased her as much as her size. And finally, that size did please her. The gargantuan rod in front of her felt so heavy on her hips and legs, and yet it still did not droop or sag under its own weight, hardened with enough blood to turn it a deep burgundy beneath the thin layer of yellow skin. Reaching out as far as she could, Adagio clutched at the head of her cock with one claw-like hand gesture, before pulling the rigid fingers back along the full length of her newest toy, luxuriating in every bump and crevice on its sensitive, vascular surface.

“Hmmmm,” she purred in satisfaction, pleased at last with her pet’s obedience. “That’s a good pet,” she praised. Deciding they had both earned their reward, she placed one hand back atop the shaft, and spoke plainly, “cum.” A flash of green filled the room and was gone in an instant, but its effects lingered. Her massive balls pulled in tightly as they squeezed ounce after ounce of hot jizz up her lengthy pole. She cried out, “Aaah, oooh!” as her forcefully pulsing cock sent ribbons of spunk streaming across her bedroom. Adagio slapped both hands flat on the wall behind her as her breathing became harder and faster. Her dick continued to send streams of semen out from her body and waves of ecstasy in toward her lust enkindled core. The pleasure stretched out across Adagio’s awareness like her lengthy rod stretching across the room. Adagio managed a devilish smirk as she recognized her pets fine grooming. “That’s gooood, pet. I never, uuh, said ‘stop’,” she gasped through the fog of her consuming orgasm.

Now, it was time to see what this power could really do. Adagio peeled her eyes open, ignoring the aberrations and dancing spots that clouded her vision and mind. She placed her hands firmly around the base of her still climaxing member, fingers failing to connect, and she whispered a final command.

“…grow.”

As she finished the syllable, the head of her dick shot forward, racing ahead of her lengthening shaft. Her package swelled smoothly, without lurching or stopping, all the while slopping bigger and bigger globs of cum onto the floor. Adagio’s face contorted against the unspeakable sensation lancing through her gargantuan tool, pleasure so intense it was almost painful. A throaty growl escaped past her attempts to restrain it, but the noise barely competed with the din of splashing spunk, stretching skin, and pulsing veins. The clamor reached a crescendo when her monolithic member crashed into her bed more than 5 feet in front of her. Landing on the mattress with a weighty thunk, her outthrusting head shoved the frame along the floor with a series of shrill, metallic shrieks. The force of her expansion and ejaculate churned and disheveled the sheets and mattress from their orderly arrangements.

Her tip cleared the far side of the bed and kept pressing forward. Her growth was accelerating as the pleasure mounted higher and higher, already far beyond any height Adagio had ever imagined possible. Her massive python was more than a foot wide, and still enlarging rapidly. It sprayed a torrent of spunk to the far wall, collecting at that end of the room and spilling out across the floor in rivers of fragrant, white goo. Her cock was far larger than her entire body as it careened towards the other end of the room, more than 10 feet from the side she leaned on. Hoping to avoid actually damaging anything, Adagio cried out, “Finish!” The climax of this drawn out ordeal was no disappointment. Adagio’s breath stopped entirely, her lungs frozen even as her mouth opened wide for a voiceless scream. The heat on her body was so intense it seemed impossible for it to be coming from her own metabolism. She was only dimly aware of her dick crashing into the far wall with a terse smack, of its head turning upward and snaking out the last few inches of her unbelievable growth, of the geyser of spunk plastering her wall as a non-stop stream surged forth from her roiling nuts. All adagio could feel was the brilliant, blinding intensity of her climax, the white-hot sensation enclosing her balls, stretching out along her shaft, and blazing like the face of the sun at the distant tip of her immense cock.

Adagio had lost all track, and indeed all concept, of time, but eventually her senses returned to her. The last few cups of splooge gurgled up from her upturned tip, sliding slowly down the white-splattered sides of the gargantuan head. The great, 12 foot leviathan of her still tumid member lay sprawled out before her shocked gaze, filling half of her room with its tremendous girth. The base of this monster spread clear from one hip to the other, and the shaft swelled even further along its first foot of length. The total package was two and a half feet across its width, tattooed with dark veins ranging from pencil thin to as thick as Adagio’s wrists. Her massive balls rested firmly against the floor in front of her, each some 3 feet in diameter, and tender from their recent exertion.

Adagio let her legs collapse beneath her, but rather than slump down to the floor, she ended up resting on her gargantuan nuts like two fleshy bean-bag chairs. She breathed in deeply, savoring the salty tinges of cum and cock that filled the room with their musk. Her titanic tool was deflating now, the magic of her amulet ferrying the blood away as it would be far too much for her body to ever hold. Her mattress creaked as the weight of dick-meat changed and shifted atop it. Her cock slithered softly as the distended tube pulled back through the great ocean of cum inundating her floor.

Although Adagio was not looking forward to the clean-up of her little experiment, she was still beyond pleased with the results. But doing anything would be quite impossible with the immovable package now pinning her to the wall, so she activated her magic one last time.

“Shrink, my pet. You’ve done well, tonight. Now it is time for you to save your strength. You’ll be needing it, for what I have planned.” She finished with a sinister grin, petting atop her shaft absent mindedly as her meat swiftly retreated inward. Her newest toy might be back to a mere 6 inches, but soon it would be joining her other toys in some expansive escapades. Adagio laughed, deep and menacing, but with a genuine sense of delight she had not known in years.
