Part 8

When Rachel regained consciousness, she found herself in a familiar space. Her memories were a little foggy, but she felt she had been here before; the all-chrome walls and floor were hard to forget. Maybe she was drunk. The faint, alluring aroma that hung in the air certainly harkened back to some strange, otherworldly night.

Her body felt funny. Though, really, her body had felt strange for the last few days now. It felt like there was a massive weight on her backside. Stranger still, her body was vibrating, shaking with the rumbling of the thing on top of her. She tried to move, but she felt pinned down...

Purrrrrrr... purrrrrrrrrrrrrr...

Rachel blinked, feeling the vibrations from something purring. She tried to turn her head, only to find it stiff. She tried to shake the thing off, unable to see or perceive it...

"Mrghrowr... sit still, Rachel."

That was Alicia's voice, interspersed between the strange rumbling purring. It sounded like Alicia was right on top of her. Rachel felt her entire body flush out of embarrassment. Were they sleeping together? She didn't think Alicia saw her like that...

She tried to stretch her arms, but found her body going strangely slack, Alicia's form sinking deeper into her. Rachel frowned slightly, feeling the concerning sensation of her body expanding, cradling Alicia, more of her seemingly bare-skin pressing against hers. Again, she blushed, her body shuddering. It was tricky getting her emotions in check, and the intimate situation wasn't helping...

Scribble scribble. Rachel paused, picking up the sound of a stylus rubbing against a screen. She glanced above her, then over, and finally found a strange sight. She resembled a woman, but she was bright green, and had a ghostly air about her; she didn't even have legs, just a wispy ghost-tail where her lower body should've been. A clipboard was hovering in front of her.

"Um...?" Rachel blinked.

"Oh are you awake?" Mira tilted her head with a smile. "Don't mind me, just taking some notes. Just keep lying there..."

"Mira??" Rachel stirred. "What are you doing here???"

"Oh, we're back at my place!" Mira nodded. "Just sit still, you've progressed quite nicely..."

"...Progressed?" Rachel murmured. "I-I dunno, my grades are still kinda lousy..."

"Oho, not your grades, silly," Mira chuckled. "The space rubber experiment. You're such a good subject... and a very supportive friend, might I add~"

"...eh? What?" Rachel wanted to tilt her head, but somehow she couldn't. "Space rubber? What's that??"

"Well, you are!" Mira smiled. "I figured you were a big softie on the inside, but now you can be a big softie on the outside too."

Rachel's eyes shifted, not sure what she meant by that. Her body squeaked uneasily; she tensed up, and tried to squirm free, but she was pinned down.

"I-I don't get it..." Rachel stammered. Mira turned her electronic clipboard, and the tablet shifted to show Rachel the camera feed. Rachel's eyes widened as she saw herself. Or, more specifically, the form she was taking.

She resembled a large beanbag, or maybe a dog bed in shape, apart from her face peering out from the side; her arms and legs had sunk into her wide frame. And resting atop of her was a bright pink... someone. She heard it was Alicia, but Alicia didn't usually have a big slug tail, or cat paws. Or enormous F-cup tits, for that matter. Rachel's gaze focused on the strange sight of her roommate. She was almost see-through... not unlike Mira hovering above her.

"H-hey, Alicia..." Rachel whispered. "Aliiiicia..."

"Ohhh, Dahlia's in a very deep sleep." Mira leaned forward, pressing a wispy hand on Rachel's cheek. "Please don't disturb her, my little pet needs her sixteen hours of beauty sleep. You understand, right?"

"I... I guess." Rachel was, internally, panicking over the strange forms everyone in this room was taking. Yet, as she inhaled deeply of Mira's strange, otherworldly essence, her emotions remained calm as still water. It must've been having an effect on her.

"'Dahlia"...?" Rachel murmured quizzically,

"Mrrrowr..." 'Dahlia' meowed quietly, digging her paws into Rachel's backside, kneading Rachel's form like dough. Rachel shuddered, moaning quietly as her body wobbled underneath Dahlia's grip. The sight of her skin stretching, pulled up, stretched thin, and packed down with repeated tugs felt exquisite to Rachel. It was like a massage that extended to her whole body.

Rachel's boneless body blorped and squeaked as Dahlia rubbed her body along the top of her form, burying her cheeks within Rachel's molten curves. Rachel's eyelids fluttered, her body shifting and squishing like a waterbed.

Mira's smile widened as she watched Rachel's slow, gradual transformation still progressing right in front of her. Rachel's body was becoming positively molten hot, her fair skin bubbling as it shifted into a semi-liquid state. As she watched Dahlia lean over to nibble at where Rachel's neck might've been, the two semi-liquid women moaned in unison. Mira paused her note-taking, and leaned forward.

"I didn't take you two for a couple, based on my background analysis." Mira murmured. "Though I suppose a lot has happened... perhaps this isn't the best time to explain the nature of 'Dahlia', as I've come to refer to her."

The two women were growing increasingly sticking, strands of flesh-hue and pink slime intermingling and mixing with each other, the two of them bubbling to the far corners of the chrome room in larger and larger pulsations, the muffled moans of two women mixed with the sloppy sounds of popping slime, and heat-induced yowls.

"Oho!~ I should observe from a different room, before the slime really begins to fly~" Mira floated up and over, her ghostly form going through one of the chrome walls; the only evidence she left behind was a layer of sickly green ectoplasm, left behind. Rachel glanced up at the strange goo.

"Must be why everything here is stainless steel... o-oh, Alicia, not there, don't... don't stop~"

Rachel swooned as Alicia—or was it Dahlia?—pressed into her form. Whatever their deal was, it'd have to be cleared up once she woke up... and once Rachel pulled herself back together.
