Part 9

Rachel's memory of the prior night was a total blur. She'd woken up again in her own dorm room once again, mysteriously spirited away from Mira's lab once again. She would've dismissed the whole night as some sensuous dream, had it not been for the state she found herself in; while her body splayed across the bed, her arms and legs spilled off opposite sides of the beds, rubbery limbs coiled into neat little piles.

She squeaked, and her limbs lashed out in turn, flailing and flopping around the floor. She paused, reflexively clenching her fingers and toes. She traced the sensation of her extended limbs, and tried to shrink them... only for her to shudder, her rubbery body squeaking further in all directions.

Stranger still was the odd suit that Rachel was wearing. It was chrome-silver, and adhered closely to her body. It looked like something out of a sci-fi comic, how it clung tightly to her and left nothing to the imagination.

"What on earth am I wearing...?" Rachel murmured in a daze, idly stroking the smooth fabric. "So shiny..."

"Ah, you're awake."

Rachel perked her head up, suddenly hearing Alicia's voice, as if she were in the room. She glanced from side to side... and then straight up, gasping as she saw a large pile of pink slime, adhering to the ceiling. It oozed downwards, an upside-down pear-shape that morphed in front of her eyes.

Rachel hadn't yet gotten a good look at her roommate's condition prior, but she could make out her face from the slime. As Alicia lowered herself more, her humanoid form was made more and more apparent. Rachel gawked at Alicia's nude form, her pronounced chest and curves, and the rather alien attributes she had now, like those cat-like ears, those strange antennae, and that enormous slug-like growth behind her, strong enough to adhere her to the ceiling and hold the rest of her body in the air. She looked as though she was flying.

"Alicia? Is that you??" Rachel gawked.

"Mmnn... yes and no..." Alicia grimaced. "Please, call me Dahlia..."

Dahlia lowered herself from the ceiling, her body squelching as she pressed two hands to Rachel's mattress, kneeling on top of Rachel's waste. Rachel's cheeks flushed as she felt their crotches press together.

"Alic-... Dahlia, you're naked." Rachel murmured.

"Yes, clothes feel, um... restricting now." Dahlia replied. She stroked Rachel's side. "Master Mira wanted me to keep an eye on you. Take notes on her behalf."

"Master?" Rachel blinked. "But that's... wh-what happened to you? What's with the name change?"

"It is a portmanteau of 'Alicia', and 'Darling'. Our bodies fused, and our minds will soon follow suit.  It feels appropriate, considering that now we're becoming one and the same." Dahlia toyed with one of her antennae. "Our minds haven't fully aligned yet; the Darling half of me is rather exhausted after... um, last night..."

Dahlia's body rippled with excitement, her breath turning hot. Rachel watched as Dahlia's nippled stiffened, elongating like a second set of antennae. She rocked her hips, her body shaking like gelatin. She leaned closed to Rachel's mouth, closing her eyes as her tongue lolled.

"Awah! Dahlia!" Rachel tensed up, feeling Dahlia's curves expanding around her, making her heftier and weighing her down more.

Rachel's limbs acted quickly, rising up like serpents to lash and wrap around Dahlia, pulling her to the foot of the bed. She squeezed tightly, yet tenderly, holding the well-buxomed pink slime alien at arm's length, her body shuddering and feverishly hot to the touch.

"S-sorry..." Dahlia swooned. "I-I believe the alien half of my being is... starved for intimacy. And hoped to latch onto you. I will... try to control myself."

Dahlia breathed sharply, closing her eyes. The rippling of her body slowed, and her breath steadied; she exhaled and relaxed.

"It's clear to me that I will need to come up with some... extracurricular activities." Dahlia sighed. "It's rather suffocating, being cooped up in such a tiny dorm."

"Well, we could upgrade to a bigger place. We might have to, what with my super-stretchy bod and your... alien-ness." Rachel chuckled awkwardly.

"Master has never trusted me with her professional work before." Dahlia shook her head. "I... hope not to betray that trust, by letting my emotions get the better of me."

"Don't feel bad! You seem like you're getting a handle on this real fast!" Rachel nodded. "I don't know what to do with myself yet, so..."

"The memories of my alien body have allowed me to acclimate quickly." Dahlia nodded. "You, though, have woken up to an all-new body. Master predicted this, and prepared this training suit for you."

"Oh, is that what this is for?" Rachel looked down at her body. She noticed a small button where her navel was. It was a power button. "What's the button for...?"

"Allow me." One of Dahlia's antennae extended forward, reached downwards to prod the button; Rachel let out a reflexive ticklish giggle, before her body was rocked with a strange buzzing sensation, an electric massage that extended through her entire body, even through to her overstretched limbs. Within moments, her body popped back into shape, her arms and legs retracting back to their typical length.

"Wow..." Rachel admired her hand in front of her. "Did the suit do that?"

"Master says you won't need it for long. Just until you get used to your new body." Dahlia nodded. "You should get dressed, though. It's almost time for class."

"A-ah, right." Rachel shimmied off the bed. "I, uh, should probably just throw my clothes over this weird suit, huh? In case of an, um, stretchy emergency."

Rachel paused, and then looked over Dahlia's form. Even if she hadn't turned into a weird, pink-slime alien, she had grown a foot taller, and a whole lot curvier and bustier.

"Um, Dahlia, are you going to be... alright?" Rachel frowned. "Won't people... freak out if you go out in public like that?"

"Yes, but..." Dahlia closed her eyes. "This body can shapeshift quite well."

Before Rachel's eyes, the translucent characteristics of Dahlia's slimy body darkened to a peachy, flesh-like hue, dimpled with freckles and goosebumps. Briefly nude, her skin flared upwards and outwards, fashioning a full outfit ensemble, with a skirt, button-up shirt tie, shoes and high-heeled socks. The clothes seemed to suit her extra-sized proportions nicely.

"We'll need to blend in and continue to live school-life, while returning to Master for further studies." Dahlia explained. "Can I count on you to keep a low profile?"

"U-um..." Rachel blushed. She hadn't fully recovered from briefly seeing a vision of a nude Dahlia sitting at the foot of her bed, and settled for a quick, furious nod.

This would be the first days of their new lives as shapeshifting meta-humans, she supposed. Little did she realize that, though the breadth of changes for Dahlia had come to pass, Rachel's superhuman mutations were still developing inside of her...
