When Two Become One

Part 1

If you love what you do, it's not really a job. Megan Skye heard this idea thrown around and, truth be told, she had taken rather well to her latest gig as a newly minted succubus. But it was Sunday now, and she was quite relieved to finally get a day off. It was an opportunity to slow down, take a breather, and treat herself a little.

She owed herself a little extra personal time in the shower this morning; normally she cleaned herself in such a blitz during the mornings, as part of a dutiful, regimented morning routine. But Sundays were nice; she could allot herself an extra five minutes of blissful indulgence.

...It didn't take a lot to get Megan excited, but it was the little things that count. And hot showers hit differently now.

Since taking on her gig, Megan's body had taken on a stark transformation, and it was in the showered where she could best explore her new proportions in the privacy of her own company. She marveled quietly at the smoothness of her own skin, which had now taken on a vivid, magenta hue. No matter where her fingers travelled, there was no evidence of any kind of body hair, nor blemish on her perfect, glowing skin. Her luscious curves had rounded out, and she had taken to wiggling her butt, rocking her hips as a narrow demon's tail wagged happily behind her. Her long hair, often content to flow behind her down to her hips like a cape, had been dampened by the flow of water; her silvery hair streamed along her back, adhering to her curves.

She moaned, cupping her size-D breasts, her dark eyes squinting. She was terribly sensitized all over, and the steam that wafted all around her bathroom excited her. Her toes tensed, squeaking against the porcelain flooring. It was something of a tragedy that she had grown so much over her transformation; her bathtub was modest, and it'd be a tight fit having a traditional bath again.

Still, a hot shower hit the spot just right, and she allowed herself to relax. She didn't even care as her pores relaxed, seeping out a pink haze of succubi pheromones that wafted about the bathroom, intermingling with the hot steam. She squeezed her thighs together as her hands worked to massage a bar of soap in between her breasts; suds of bubbly soap trickles down her legs in streams as she cupped her hands, splashing it against her chests.

Her hair had gotten out of control over the last stretch; she felt like she was going through a quarter of her shampoo and conditioner every time she hit the shower. Though she supposed this was a good excuse to linger even longer in the steamy bathroom. She didn't want this to end...

DING DONG!

"...!"

Megan's eyes widened as the sound of her football rang clearly through her home. It was then that a dreadful fact occurred to her. She had gotten so caught up in her new job, and her new body, that she overlooked one massive detail:

Today was a Sunday.

"Megaaaaan! Are you ready to go?" A familiar voice called out, just barely loud enough for Megan to hear.

It was Celes. She was stopping by to pick her up for church.

There were a lot of issues Megan had to contend with at the moment. She needed to get out of the shower. She didn't have her Sunday finest selected; heck, she was leery if anything would even fit her voluptuous proportions. She was anxious as to how Celes might react; she understood that Celes had some bad history around demons and succubi, especially concerning her horny next door neighbour. Actually attending church this particular week completely slipped her mind, which was telling, considering she and Celes made it a weekly routine by now.

And the anxiety was billowing again; her pores continued to hiss and pump out pheromones, casting it upwards like air escaping from a deflating pool floatie. She hugged herself with one arm, the other scrambling to shut off the hot water.

"Just a minute!!" Megan blurted, scrambling for a towel to protect her modesty as she dried herself off. Dabbing off as many beads of water as she could, she rushed out of the bathroom and to her wardrobe, scrambling to find something suitable to wear.

"Mrgh... c'mon, why does nothing fit right anymore??" Megan grunted, trying to clasp the buttons of a vest over her pronounced buxom. Everything she borrowed from Kamika fit just fine—mostly because Kamika had very lofty views of her own body—but everything that Megan already had in her wardrobe felt two sizes too small. And nothing she got from Kamika would be remotely acceptable in the middle of a sermon.

Megan was getting increasingly agitated, and her emotions were reaching a fever pitch. The unabated flow of pheromones from her skin didn't help matters; the haze of pink fog wafted from room to room in her house, suffocating everything, though Megan didn't seem to notice at the time.

There was another knock at the front door.

"Uh, Megan, I'll just drop a couple of the things I borrowed from you in the living room!"

The front door was unlocking. Megan's face went pale, she was horrendously underdressed in nothing but her undergarments.

"O-okay that's fine!!" Megan blurted, redoubling her efforts to get the straining fabric over her chest. She huffed, giving up and trying to get a pair of dress pants up her pear-shaped waist. She bounced up and down, the tail behind her thrashing fiercely.

"M-Megan..."

Megan grimaced; she could hear Celes' voice a little closer now; she glanced to her bedroom door, confirming that it was closed.

"Listen, Celes, I got into some new work recently, s-so I might look a little different, but once I get everything sorted, please don't panic, okay?"

Shlorp.

Megan's eyes widened. Something lurched from underneath the doorframe. It was slick, wet, oozing... purple.

"Celes!?" Megan shot up to her feet. The pile shifted slowly towards her, as if spilling into her room. Small tendrils formed, pulling the central pile along.

"Meegaaaaaaan...~" A familiar voice burbled from the pile, monotone and dazed. Megan had seen this sort of behaviour several times already, and the realization finally dawned on her.

Her pheromones really were out of control this time; they flooded her entire home, and they had gone and reduced Celes to an indistinct pile of mush. Did she still have eyes? Megan loomed over her with a curious, concerned look...

Which, in immediate retrospect, was not the most sound decision Megan could've made; a tendril of purple ooze lashed out to wrap around Megan's ankle.

"Ah-" Megan staggered back, feeling Celes' warm, damp grip tighten around her leg. The contact alone set a shot of electricity up Megan's leg. rippling through her entire body.

Megan groaned, her eyelids fluttering, as her hand flailed anxiously to grab for the back of her chair. She tried to press her weight on it but, no matter how she adjusted her grip.

She glanced to see where she was gripping, and gasped. Her arm had taken on a sleek, shiny quality that reminded her of bubblegum; beads of what appeared to be sweat trickled down her arm, coating her fingers...

...Trailing down the backside of the chair, and dribbling to the floor in pink dollops. Megan swallowed, studying how her entire body had been overtaken by the slick material. Her legs quivered, threatening to capsize, as her body lowered slowly to the ground.

Another bodily side effect of her succubi transformation: she found shapeshifting to come as naturally as breathing, but she didn't much care for melting right in front of Celes. Though it appeared Celes didn't have similar reservations at the moment.

Megan's breath grew hot and haggard as dribbles of pink slime fell off of her body, spilling into the purple ooze that presently comprise Celes. The energy inside of her spiked as her legs smooshed together, her thighs pressing together as she slumped to her knees. Heat rattled around in her body with no release, and her body had only to yield to it...

Megan slumped forward, her form completing melting into a puddle, oozing and swirling along with Celes' biomass. Not a word was muttered between the two of them as their minds blanked in unison, masses of pink and purple swirling, mixing together on the floor of Megan's bedroom like paint.

The puddles of ooze and slime shrunk as they melded together, tendrils smacking and flopping about as they coiled, adhered, and piled on one another. The ooze pulsed, wet sucking sounds filling the room as it grew larger, taller. Both Celes and Megan seemed oblivious to the changes happening to their bodies.

...And then, as if chiseled from clay, a form emerged. Extraneous ooze traveled down the lengths, settling into curves, limbs, and appendages. ...And with each passing second, the distinction became clearer and clearer.

If one squinted... the swirling pile of purple and pink ooze almost looked like a person.

Part 2

At this point, it was impossible to tell where one girl ended and the other began. Both had been so thoroughly reduced to slime, and the slime so eagerly crawled to the center of the room. Swirls of purple and pink wrapped around each other, forming beautiful currents as they blended together, like cream poured into a cup of coffee.

The purple and magenta hues lightened up, glowing up to a peach-like hue, taking on a fleshy texture as dewy strands of ooze sunk in through newly opening pores. The pools of ooze furthest from the center twisted, narrowing into wild strands of hair; dominantly white, like Megan's, but with striking violet streaks; a couple strands of hair flowed together into bound strands, smoothing out into wet tentacle-like appendages, reminiscent of Celes' hair tendrils.

A heavy-set body lay on the floor, eyes closed as if in a peaceful sleep. The last of the ooze curled around her lower body, curving around her large, child-bearing hips and her soft yet powerful thighs. The woman moaned, her toes scrunching against the carpet.

Her eyelids fluttered open, revealing a pair of heterochromatic eyes—one blue, one brown. She tried to trace the feeling of her body, feeling a pronounced heaviness on her chest. She sat up from the ground, allowing her pendulous breasts to bounce and wobble in response.

The woman cupped them carefully, admiring their size. It wasn't as though Megan was lacking in the chest department only moments prior, but neither Celes nor Megan compared to the size of the woman that sat in the middle of the room. How big was she?

She hobbled up onto her feet; the room felt a lot smaller than she remembered... as she got up, raising her ass to the ceiling, she wiggled it reflectively; from the base of her arcing back, a pair of narrow devil tails each tipped with a heart-shaped spade sprouted from just above her butt, wagging and wrapping around each other. From her lower back, a pair of bat wings sprouted and flapped, revealing their impressive wingspan, before settling around her hips like a skirt.

The woman that stood in the room was neither Megan nor Celes. But something... or rather, someone in between.

She turned to a mirror to appraise herself; she brushed back her hair, allowing a second pair of bat wings to slip free, sprouting from the sides of her head. Some instinct gave her an inkling of her current size, like the measured eye of a skilled seamstress could eyeball someone's measurements even before the tape came out.

Six foot four. That would explain it. She didn't quite need an extra cup size... but her breasts felt much more emphatic on a model with more Amazonian proportions. Not to mention her pear-shaped lower body, powerful and able to offset the extra weight.

She lowered a hand to her thigh, admiring their smoothness, their softness. Heck, her whole body was remarkably soft, and sleek at that. And not a drop of gross slime to be seen. It was something of a relief for the woman.

...She looked herself over in the mirror, smiling to herself and rocking a couple of poses. She found herself chuckling to herself, backing away from the mirror.

"Looking good!" She cheered herself on. She tilted her head. "Mm, there was somewhere I had to be, huh?"

She gave it some thought, searching her memories...

"...Oh! Church! Right." She nodded to herself, focusing inward; there was no way her old clothes would fit anymore, so she would have to produce some more suitable attire.

...Well, suitable was the goal, but part of her wanted to feel good too. Her skin rippled on its own as she focused inward; her skin shifted, pushing outwards as her flesh turned into fabric. She gained a couple more inches as a pair of three-inch heels wrapped around the soles of her feet. A dark-blue suit that seemed to hug and adhere to her curves materialized to cloth all around her... though perhaps her cleavage was a touch exposed. Even with her extra height, her wildly long hair extended down to her perfect ass.

She leaned over to a sunhat abandoned on the floor—she was rather attached to it, it felt like—and gingerly affixed it to her head. With a nod, she was ready to go...

Ding dong!

"Mm?" The woman cocked her head up. Her eyebrows furrowed. "I wasn't expecting anyone today..."

Ding dong! Ding dong! Dingdongdingdongdingdongdingdongdingdong-

"O-okay, I hear you, I'm coming!!" She called out, scrambling for the door. She huffed to herself, catching her breath as her breasts ceased their bouncing, before reaching for the door handle...

"...eh? S-Tan?" The woman blinked.

"Hey girls!!" S-Tan waved cheerily, dressed for the summer weather in pink short-shorts and some merch of her idol troupe, the Sinful Stars. Her eyes bulged as she took in the sight of the woman. "Oh my are you an impressive specimen...!"

"Um?" The woman cocked her head to the side. "I-I kinda just woke up like this, hehe..."

"Oh, you don't have to be modest, you just pulled off some high level succubus magic!" S-Tan beamed. "Double Double sent a report to me, and I was just so excited I had to come see for myself! I heard of succubi merging with other succubi, but a normal... well, abnormal human, well, that's remarkable!"

The woman smiled politely, confusion written on her face. She recalled parts of it from her frazzled memory. "Uh... r-report?"

"O-oh, you probably forgot, what with the mind-melting, y'know Double Double's keeping an eye on all your succubus activities from the shadows, right? Remember?" S-Tan jumped up to pat the woman on the cheek, though the pat seemed to have more of a slap-esque impact...

"ACK! O-oh, right..." Her cheeks went aflush. "I'm... catching up on matters, I was just about to get to church and-"

"You remember your name, right?" S-Tan beamed.

"Eh? Um..." The woman pondered. Two names came to mind. "There's Megan and... and Celes, but..."

She seemed to be two minds about it literally.

"Okay! Megales!~" S-Tan clapped her hands together. "It fits, right? Omigosh, I'm diggin' this plus-sized look you got going!~"

"A-ah... thank you." The woman nodded sheepishly, prodding her fingers together. "Megales... hm..."

"Wow, this is really impressive, usually there are more problems with two slime succubi fusing together... I guess you two really are on the same wavelength." S-Tan cocked her head to the side. "I wonder if you two'll end up partners for life!~"

"...Partners... for life??" Megales blinked.

"Oooooh this is exciting! A real soul union!~" S-Tan cooed. "O-oh, don't let me keep you from what you were doing, but lemme just..."

S-Tan pivoted behind Megales, her hands planting themselves just above her butt; Megales was given quite a jump, her cheeks aflush; was she being groped??

...She was kinda into it too...

"E-excuse me, wh-what are you doing??" Megales asked in a frantic whisper as S-Tan's warm hands massaged her backside.

"Juuuuuuust putting some things away! Don't wanna get in trouble with the church folk~"

S-Tan winked, her hands working to ball up and push the length of Megales' demonic tails back into it. She patted her lower wings gingerly, ensuring they sunked back into the heavyset succubi's skin and formal wear.

"Okaaaaay! I can't reach for your wings up top, you take care of those for me!~" S-Tan smacked the spot where Megales' tail used to sprouts, eliciting a yelp from the bashful woman. Her cheeks were glowing at this point.

"Th-thanks for... covering for me." She thanked S-Tan carefully.

"No worries! You two have a happy forever after together, okay??" S-Tan beamed, running ahead. "I'll be keeping an eye on you two~"

"...Ah..." Megales waved gingerly. This all felt a little strange... and the 'forever' part sounded a touch concerning.

...Weren't there other people she had to be worried about? Perhaps a visit to the church would clear her mind...
