[Story Listing]

---

Jessa hadn't seen her bestie Cammy in a while, and she was beginning to worry. The holiday season was well underway, and Jessa had finally gotten time off from her job to prepare for the parties near and far that were sure to follow. She had been trying to reach out to Cammy via text, then email, for the last two weeks, but she never got a response.

Jessa was getting worried. Cammy was always pretty eccentric, hyper fixating on one thing or another; she was a science student with a promising future ahead of her, even if it seemed that her ideas often outpaced what technology could accomplish, so her scattershot mind was more charming than concerning. Jessa had been indulging her curiosity for a month or two now; it was back in late October when Cammy was already excitedly searching for recipes on the perfect hot cocoa recipe (a pinch of pumpkin spice set her on this path of inquiry).

Her email history followed a long line of recipes for different ingredient combinations in pursuit of the perfect cup of hot cocoa, and the search for answers seemed to take Cammy to stranger, more far-off places. Then, one day, Cammy confided to Jessa that she had a hypothesis that could CHANGE EVERYTHING, and she had to look into it. Jessa replied, asking for her to elaborate, but she was met with radio silence.

This was a month ago and, with the holiday season finally arrived, Jessa hoped that Cammy was ready to shelve her plans, settle on something, and spend some long-overdue time with friends and family. But with the silence she was being met with, Jessa decided it was time to visit Cammy herself.

Jessa was already driving to the rich folk side of town, driving slowly to not slip on the icy roads, but also to admire the sheer opulence of the decorations put up, and the stately manner of the homes. This seemed to be an area of old wealth and techbro startups; it didn't seem like Cammy's scene, but after making a killing off of the invention of vacuum-sealing, self-adjusting condoms, Jessa supposed it was well within Cammy's rights to indulge a bit.

But as she approached Cammy's estate, Jessa was getting worried. She wondered about how she would get inside, getting out after parking on the curb.

"U-um... this is Jessa." She awkwardly announced herself. "Are you in there Cammy? I haven't seen you in a- o-oop!"

Her finger buzzed as the panel lit up, lasers scanning her palm. She recoiled her palm, the curious mechanism whirring and clicking, before it PINGED! an affirmative. Jessa was very puzzled... at least, until the speaker crackled to life.

"OMIGOSH, JESSA!!" The speaker rattled. "I had a -MAJOR- breakthrough on that thing we talked about! C'mon in, the front door's unlocked!!"

The lock clicked, and the gate creaked open. Jessa was reassured by the sound of Cammy's voice enough to not let the creepy gatecreak get her down. Though she sounded hyper... Well, more than usual.

"I hope she didn't hop herself up on caffeine too much..." Jessa muttered to herself, wary of the prospect of her bestie putting herself through an all-nighter again. Jessa approached the long walkway to the front door. She sniffed the air, picking up the faint, sweet scent of chocolate in the air. She licked her lips... then frowned, annoyed that her friend was still fixating on that. She'd have to give her a talking to... frick, she thought Cammy might've died or something.

She approached the front door and let herself in. She found herself in an impressively spacious, though sparsely decorated foyer. It seemed as though hardly anyone lived in it at all, if not for the strong smell of chocolate billowing about the room. There were notes of cinnamon and espresso as well... Jessa moaned blissfully as she removed her heavy winter garments.

"Cammy?" Jessa called aloud, her footsteps echoing in the foyers. "You in here? Caaaaammyyyyyy!"

Cupping her hands to project her voice, she stepped forward... unaware that a robotic arm, tipped with a syringe, was descending from the ceiling right behind her. It hovered above her head, approaching the back of her neck, until...

SHNK! It stabbed into her neck, injecting a white substance into her body.

"OW! HEY! What was... what whash...??"

Jessa slurred her words, feeling like her legs were turning to jelly. Her vision grew dim as she collapsed on the spot with a hard thunk.

Jessa stirred awake in a daze, finding herself in an oddly barren room. Apart from the sweet aroma still filling the air, Jessa could've sworn that she was in some doctor's office.

"Ugh... my head's all mushy." Jessa murmured, rolling over to sit upright. Strangely, her entire body seemed to wobble with a pronounced boing, and as her fuzzy vision became clearer, she realized that there was something pale and white in her peripheral view. She rubbed her face, kicking up a cloud of... something like dust?

"God... I feel funny... huh?" Jessa paused, her eyes still covered; she tried to peek through her fingers, but her fingers wouldn't come apart. She removed her hands to get a better look, and gawked at their strange appearance. It was like she was wearing mittens, her fingers all fused together, save for her fat little thumbs. Her hands, her arms, her body was dusted with powder, and white as snow.

And she realized what was in her peripheral vision; the curvature of her swollen breasts, which both grew three sizes from before. If her face could grow any paler, it certainly would've; she kicked up more strange dust—powder? flour?— as she hopped to her feet. She looked herself over in a panic; her previously athletic body had really rounded out, her breasts perky and perched upon her swollen belly, her curvaceous thighs bubbling out, and her hair... her hair!?

She felt for her hair, feeling a pair of twintails there before. But they seemed to be strings of... marshmallows? She felt herself all over, the sensation of her soft body yielding to her touch as she tried to make use of her weird mitten hands. Wherever she pressed, her body would depress, and then pop back into shape. She felt large, yet somehow... lighter, too? She hadn't realized she had grown several feet, standing over eight feet tall...

"Wh-what is this stuff??" Jessa muttered, blinding her beady little eyes. "I-I'm a giant flan or, or something!"

"A marshmallow!" A familiar voice blurted from the next room over. Jessa paused her self-examination long enough to gawk upwards, the door to the room swinging open to reveal...

"CAMMY!? What... what happened to you!?"

The room filled quickly with the saccharine aroma of luxurious hot cocoa. Jessa recognized Cammy's voice, but her body certainly wasn't anything she remembered. She was nude for one, her body sopping wet and oozing like slime, a trail of thick liquid flowing behind her. Her long tendrils of slimy hair flowed down her shoulders, sinking back into her liquid skin.

"I turned myself into hot cocoa! And you..." Cammy oozed forward, poking Jessa squarely in the chest. "...are my secret ingredient!~"

"I'm whaaaAAAAGH~" Jessa swooned as one of her breasts thirstily absorbed some of Cammy's liquid form. Her body tingled all over with an oppressive heat, her light and fluffy left breast tinging a light brown, swelling another cup size and saggy; it looked strange next to her perky, still-white right breast.

"Wh... what did you do..." Jessa's eyelids fluttered. "D-don't stop..."

"There's more where that came from! C'mon!" Cammy got underneath Jessa and scooped her up in a bridal carry. Despite Jessa still having some three and a half feet on her and looking quite chubby, she seemed to weigh as much as a box of oranges! Jessa kicked her heads frantically as they surged forward.

A couple rooms over, Jessa's eyes bugged out as she saw a massive vat of luscious, piping hot cocoa! She could barely utter an objection before Cammy, now a slime woman made of the same stuff, dunked her right in before hopping right in herself.

Jessa yelped in surprise from the heat, wondering if she was going to get boiled alive. But there seemed to be a different sort of heat coursing through her like electricity. Her body trembled; she trembled and panted as her body thirstily absorbed the hot chocolate around her. She exhaled steam as her body slumped deeper into the vat.

She was swelling, growing even further, starting with her hips, her ass, and especially her breasts swelled out, growing heavy with the liquid weight. Her soft, white body took on a milk-chocolate brown tinge as she moaned, the hot cocoa splashing within her as she rocked back and forth.

Her nipples twitched, and grew increasingly erect. She was so hot... she wondered how much longer it would be until she started melting on the spot. She saw parts of her beginning to liquify, starting with her toes, cloudying up the delicious cocoa.

The surface of the cocoa began to stir and, as if breaching the surface, Cammy emerged, scooching up Jessa's fat marshmallow belly. She beamed excited, rubbing around her navel as if she were pregnant.

"You're coming along nicely, babe!" Cammy giggled. "You're just the thing I needed to make it perfect!~"

"Cammy... I-I'm melting..." Jessa whined. "Am I gonna die...?"

"Nope! Your body's constantly remaking and puffing up again." Cammy explained with a smile. "You might feel a little melty... ooh, let me see how much you're holding!~"

She reached forward, cupping the underside of one of Jessa's fat breasts, sloshing it back and forth. Jessa bit her lip so hard it slid to the back of her throat, before reforming. Her chest spasmed, and her nipple spurted a jet of hot chocolate; it splashed right into Cammy's face, who absorbed it quickly in turn.

"Aha! Perfect! Ooooh, you're lactating hot cocoa now! This is so exciting!~" Cammy leaned forward, pursing her lips as she pressed them around Jessa's breast. She moaned, drinking hungrily from Jessa's buxom.

Jessa's eyes rolled into the back of her head, arching her back as most of her overly soft, molten-heated form pressed back into Cammy. The sensation of Cammy riding on top of her, kissing her chest, gripping her fat pussy... it was too much.

On top of that was the unbearable tingling pervading her whole body, her heavy and swollen body rubbing against itself as the vat of hot cocoa swirled all around her, penetrating every part of her in waves. She leaned against the side, an oozing arm more resembling marshmallow whip, clutching the side as her body rocked back and forth.

Jessa hadn't perceived how big her body had become, taking on all the hot cocoa. Her body, already enormous, had doubled in size in a matter of moments. As the vat creaked under her weight, she pawed at her free breast.

"Cammy... l-lemme try..." She moaned weakly. Cammy, without raising her lips, shoved Jessa's cowtit right up into her open mouth. The flavour was exquisite, luscious and thick, with a hint of espresso, and some spices... so many sorts of chocolate blending together. It was like drinking hot pudding!

"Oh my fffuuuuu..." Jessa moaned, her body wobbling with a sudden growth spurt. Her body swelled to take the form of the vat, the metal container creaking under the stress. She winced, her tits gushing hot cocoa with every painful expansion, until finally...

CRASH! Sweet release.

Jessa didn't seem to notice as she landed on her fat, pillowy ass, her marshmallow body continuing to absorb the hot cocoa spilling across the polished floor. She must've grown well past twenty five feet tall, each of her breasts the size of boulders and her ass the size of weather balloons. Cammy lay cradled between her fat breasts, slurping greedily from Jessa's chest.

"So gooooood..." Cammy swooned. "You're perfect Jessa, you know?"

"Mm... mmmph...~" Jessa moaned happily, her body wobbling back and forth, filling out the chamber as her cocoa-logged body pinned her to the floor. She massaged her breasts, urging more cocoa to gush forth like chocolate fondue, the nonstop cycle of absorbing, expelling it, and absorbing it again exciting her over and over...
