Coo Coo for Coco

"Hey Johnny! You wont believe what came in the mail today!?"

An excitable, plainly dressed man named Corey shouted as he ran towards the kitchen carrying a large cardboard box. His roommate Johnny was there chewing on some eggs and caffeinating himself. He hopped a bit as Corey slammed the box on the table, completely spilling his coffee.

Nearly clawing open the box Corey said, "That Vtuber we both like, you remember? Kiryu Coco? Well turns out she actually is selling some of those bizarre AsaCoco products!"

Ripping open the box revealed many different limited items: A canned drink, a hammer, a t-shirt, and a dragon tail butt pl—

"Oh sorry, uh that is mine!" Corey nervously said as he swiped and hid the object from sight, slowly backing away. "Uh, you are free to take whatever you want of course."

Johnny sluggishly watched his embarrassed friend, failing to fully hide the butt plug, back into his bedroom and fumble at closing the door. Silence having returned, Johnny began to peruse the items before him. He too was a big fan of the Vtuber Coco, but even he couldn’t fathom that they actually made those joke products she always went on about as a joke. Seemed like a cheap way to make a buck off your obsessed fans. He then noticed near what appeared to be a soda can was a packaging note that said “Down some carbonated AsaCoco and feel the rush!”.

“Well… I could use some more caffeine.”

In the bedroom, Corey stripped down aside from his plain black longsleeve T-shirt. He was pretty small for a guy, 5’5” yet a bit stocky. He never felt inadequate about it though. Heck he had a thing for taller women, which may have been one of the reason he gravitated towards Coco as a Vtuber. Apparently she was one of the taller ones at around 6 feet. The only reason height was on the brain for him was because of the size of the butt plug he held and whether it would fit in his small frame.

He traced the ridges of the dragon tail that looked like a spitting image of Coco’s purple, plated segments on the top half of a thick, lighter purple, snake bellied dragon tail. He’d never felt an actual dragon tail, but this was as close to feeling real as it got he imagined—a real high quality product. The head of the butt plug was as a shiny silver that seemed obviously fitted for a size larger than his. Nothing ventured nothing gained though, and he confidently, yet slowly, slid the bulb into his asshole.

He shivered in delight, his ass clamping a few times as it settled inside him. He giggled thinking back to the product advertisement that advertised it as absorbing AsaCoco directly through your rectal lining. Coco certainly was quite the joker, but he had fallen for it. Corey couldn’t complain though, it felt amazing! It felt… like it was moving?

The bulb inside his ass suddenly began to tug upward like it wanted to escape. The unexpected thrashing sent his senses reeling a bit and he planted onto the bed. Staring behind he saw the entire fake tail whipping about as if it were alive! The tail then thrust forward and with an upward motion, bringing with it a shockwave of pleasure. As worried as he was, his dick began to stiffen quickly.

Corey was in a panic, but felt too inebriated by the pleasure to force himself up off the bed. It shouldn’t feel this good should it? Hell, it fell like the anal plug was moving around outside of his anal cavity at this point, the entire tail shifting into a higher posture above his butt cheeks. Something was digging into his lower back and stabbing his tail bone and he could feel extra weight dragging down on his backside, new sensations prickling at his lower body. Slowly but surely he could feel a whole new appendage emerging, the bone and cartilage all his own, its movements tied to his will yet seemingly possessing an excited life of its own. This appendage reacted much like his cock, stiffening up as pleasure coursed through it like an erogenous zone. The only explanation could be that he had… had a…! “A tail!?”

Corey screamed as he saw the tail of Coco the Vtuber fully attached and growing out of his own body. It was far too oversized for his smaller frame and was weighing him down, making it difficult to raise himself up. It seemed to have even grown longer since connecting to him. He needed to get out of here and have Johnny get help. But fuck it was so hard, the hastening pleasure overpowering him like a spell along with the new addition to his body working against him, wagging excitedly.

“What the fuck is happenohhh!”

Corey wasn’t given much time to contemplate as every bone in his body began to rattle and throb. It had been a long time since feeling a growth spurt, but it was unmistakable that this was one, every bone aching and lengthening. All of it was masked under a wave of ecstasy though, his body clearly excited over gaining some inches. His legs spread wide as they elongated, followed by a different kind of growth in his hips. His pelvis was widening with harsh snaps, a flexing build up of mass in his ass cheeks following each one.

Traveling from the base of his new tail, loads of new muscle tissue and fat began to pour into key areas around Corey’s body. He clamped his legs together as they began to pulsate, the traveling mass bloating his thighs, much of his manly muscle eaten away by feminine firmness. The cushion of his thighs provided a nice suffocating treat to his cock, causing Corey to cum profusely for a few moments while wailing in confusing bliss. As for his calves, ankles, feet, toes, all of them slimmed down into fit, sloping delights.

Another explosion ravaged Corey’s ass and hips, blessing them with considerable girth, creating a picturesque image of tight, wide, sculpted beauty that could now more proudly help lift his tail. The tail curled, pleased with the results. Afterwords the squirming power within him seemed content down below and began to move upwards, dragging his spine down into a finer dip as it did. The ache in the bones of his torso and arms intensified, and he watched, while keeping himself propped up, his arms lengthening and slimming as well as both hands losing all sight of the grit and strength they once possessed, turning into smooth delicacies with refined, claw-like fingernails. Seeing his shirt sleeves travel up his arms made it evident how much height he was gaining. His shirt was becoming smaller and more fit to his frame; at his midsection it was lifting high enough that the convulsing mass that was his stomach was revealed.

Corey was losing it and knew he had to make a move so he willed himself with all his reserved strength and rose up from the bed, stumbling towards the door of his bedroom, back slamming into it. He gazed down at his changing body--which was now a half foot taller—legs feminized, girly hands grabbing at his stomach that was sucking in and flattening with tender tonage. Corey cursed and moaned as an obscene amount of vigor powered its way throughout his body. The sides of his tummy caved in with several bursts and his core tightened. During each burst his body bucked off the door frame and his cock fired off a long rope into the air, his hands palming down on the shaft in a frail attempt at stopping it.

His whole body was alight, dick now leaking pre-cum consistently—the viscosity becoming more watery. Feeling around as he flipped over chest side onto the door he noticed his balls had disappeared completely inside his body. He had a very larger inkling of what was happening to him, made more real by a familiar voice rising within the back of his mind, mingling with his thoughts.

“What the fuck!? It won’t stop! Ahn! Hooh, Johnny! Johnny I can hear her!”

Corey screamed out to his friend in rapturous tones, unable to give off the impression he was truly panicked any longer despite the intent. He finally flung open the door and called out once more to his friend in the kitchen. What he saw though made his whole body clench nervously.

Thrashing on top of and gripping to the table in joyful agony was his friend, undergoing a similar transformation as himself. The same large dragon tail whipped wildly behind him and the same bodily proportions had been given to him. Only Johnny seemed further along, his hair growing long and orange like a certain familiar character. His breasts too were inflating violently beneath him, kicking his body into the air with each expansion—they looked ready to burst out of his shirt.

“C-Cocooohh!” Johnny moaned, drool pooling from his mouth. “It’s going straight to my head!”

There was no denying it now as Corey looked at the spilled over soda can near his friend. These products, they were not just getting them hooked on AsaCoco, they were turning them into her!

A rippling wail of ecstasy suddenly came from Johnny, his voice cracking at the peak of it and breaking into the voice the the Vtuber Coco herself. His face began to scrunch and crunch down into a smaller cranium, features softening and sharpening, his mind breaking under the onslaught—both eyes fading into the signature blazing orange of Coco. Distinct, sharp, lengthy ears quickly yanked out from his head, sending a squeal from his lips and and eruption from his cock, the thick cum thumping against the underside of the table. The pure rapture sent him dragging himself forward, flattening his cock underneath the table. It continued to cum as the visage of Coco devoured his masculinity, the stiff rod dragging on the surface of the table as it began to shrink, leaving a sticky snail-trail in its wake.

“No! No, no! Oooh!” Corey yelled before the changes grabbed hold of him once more, this time determined not to let go.

He fell to the ground in a seated position on his tail, back against the wall. An unrelenting buildup of fat jiggled to life on his chest, rippling chaotically the larger it ballooned out. His nipples swelled in size and poked at his shirt excitedly, the warmth from his new dragon milk teasing them below the surface, making them sensitive. Desperate, he grabbed and pressed at his growing breasts as they filled up, soon becoming too wide for his hands to grasp. The sheer size caused them to sag greatly on his chest and swing wildly while his shirt was conforming more and more to their shape. They were overtaking the width of his silhouette and yet still showed no signs of stopping. Complaining wasn’t really on the forefront of Corey’s mind anymore though, his hands groping now more than trying to contain, his dick jettisoning out clearer fluids onto his tail as it began to pull in towards a flushed slit swelling between his legs.

“C-Cooocohh! C-Coco! Cohhh!” Corey moaned, his twitching eyes blazing with the same pupils as the Vtubers now, his face starting to contort similarly to his friend. Both his ears lengthened and two hard nubs broke the skin above his temples, and his teeth sharpened with glee. Human and Dragon, a beautiful idol, yes that is what he was becoming! His angular eyes, pointed chin, skin soft as silk, and hair cascading down into a long, orange mane. Coco was pushing herself free!

A wet, salivating slit now open and beckoning his cock inside, Corey matched his friends orgasmic cries with his own, moaning, “She’s in my head! I can feel her in my head! Coco! Yes! Cocoohhh!! Aaahhn!!”

His mind finally breaking under her influence, Coco’s voice broke free, and Corey’s body sped through the rest of its changes. Her breasts demanded more, so her upper back snapped broader and filled with extra strength to carry them. In response her chest expanded yet again, perking up a bit this time as they rose out nearly a foot from her torso, each tit almost the size of her head. The small nub that was left of her dick celebrated by burying itself into her folds as a new clitoris, pumping electrifying pleasure throughout her.

Coco wasted no time fingering herself, the wet slick sounds tickling her eardrums. God she was hooked on her own body, hooked on AsaCoco. She was so close, so close!

The Johnny Coco was going to town on her pussy in her own way, curling her tail under her legs and pistoning the thick head of it into her tight snatch. Both Kiryu Cocos wailed in delight as Dragon magic bubbled within them, pushing them further and further to the peaks they yearned for.

“It’s coming! It’s coming!” Coco yelled.

“Yes, I can feel it!” the other Coco moaned.

An inhuman orgasm rattled both Cocos body’s, every muscle tensing and twitching as they cried out together. In perfect unison fluids squirted out their plugged snatches, soaking their still sliding fingers and tail. Their brown, crooked dragon horns burst violently out from their heads in one go, their ascension from fanboys to Coco herself complete.

After a few moments of recovery, the Coco on the floor commented, “Wow, I didn’t expect my products to pack such a punch.”

The Coco at the table giggled and then walked over with a slip of paper, showed it to the other Coco and said, “I think it is working just as intended.”

The slip of paper, which had come packed with the products, simply read,

To my lucky, dedicated fans! If you are one of the few to buy these products know that you are a big help! Being a Vtuber can be hard, but I want to spread AsaCoco around the world! But there is only one me. That is where you come in! Won’t you help me out? I promise the full AsaCoco experience!

“I’m a genius!” Coco declared with an excitable yet sly look.

The other Coco laughed in agreement then said, “Now even more people will be able to enjoy AsaCoco.”

The two lively girls clasped each others hands enthusiastically, their glimmering eyes communicating the same idea to each other. Together they cheered, “Let’s get streaming!”
