Part 10

Rachel had to get accustomed to school life, and settle back into things. On her way over, she worried about giving her secrets away, and outing herself to the student body as some sort of elastine freak, but once she arrived, she decided that it'd be best to just go about as she always did, and not think about things too much. Not thinking is something she did quite well, after all.

All the commotion from the prior night had left her exhausted, and she couldn't keep her eyes open, routinely dozing off. Her eyelids felt heavier than usual, and it didn't help that they kept sticking together. During biology, she kept trying to shuffle in her seat, fidgeting enough to keep herself awake, engaged, and in the moment, but the squeaking noises her body gave off were disturbing her neighbours and earning her looks from classmates and the professor. She sunk into her seat, her back and ass adhering to the curvature of the backrest.

She only stirred awake from her most recent nap when a chair slid up next to her along the long table all the students shared.

"Rachel! Hiiii!~" A familiar, bubbly voice chimed in next to Rachel.

"Uhhh...??" Rachel peeled her hand from her cheek, revealing a hand-shaped imprint in her doughy, misshapen chin. This woman had a pleasant air about her, and entrancingly bright, green eyes.Rachel squinted. "Mira?"

Not in her ghostly apparitional form, at least; despite her seemingly carefree attitude, she at least had sense enough not to start spooking the student body.

"Yeppers! O-oh no, did you bend yourself out of shape again?" Mira leaned forward. "Lemme fix that for you..."

"Uh? W-wait, I- mmph!?"

Mira brought her lips to Rachel's in what appeared to be a passionate kiss... but in actuality, she was exhaling a sweet-tasting mist into her mouth, which swirled around inside her cheeks. Rachel's eyes widened, and then fluttered; it felt soothing, like a relaxant, her concern and worries ebbing away in an instant.

Her mind meditatively focused on her body, feeling Mira's mist travelling through her; first, Rachel's cheek popped back into shape. Then her legs, twisted in several loops under the chair, unfurled until they were separate and her heels squarely touched the floor. Her ass inflated, and she felt a bit more cushioned. Finally, her chest went up another cup size to better fill her bra, somehow losing tension and definition over the course of the day. Mira squeezed the undercup of her chest to test its firmness, something which got a giggle out of Rachel.

"S-stop, omigosh!" Rachel's cheeks flushed as she parted from Mira, letting out a laugh, her throat and nostrils releasing a wispy trace of Mira's ghostly fumes. The entire class was staring at the two of them, and the professor at the front was glaring daggers at them both.

"Ladies," the mustachioed man muttered. "Let's save our public displays of affection for after class, yes?"

"Mmhm! Focusing on the groupwork!" Mira nodded, chipper as ever, before scootching a little closer, lowering her voice. "Feeling a little better now?"

"A-a bit..." Rachel pressed a hand to her chest. "Thanks for, um, making the fancy suit for me."

"Oh, it was nothing! Thanks to the special material you provided, new tech like that is a cinch!~" Mira beamed.

"Uhhhh... huh." Rachel rubbed the back of her neck. It was weird not feeling a spine there. "Did you... just enter this course? I could get you my notes-"

"Ohhhh I think I'm good. I reverse-engineered the human genome to make you, my adorable little masterpiece~" Mira emphatically booped Rachel on the nose. "...and I figured I'd make time to study you while Dahlia's away."

"Mm? It's weird for Ali- for Dahlia to skip class." Rachel tapped her chin. "Dahlia was pretty hardcore about her studies before the... the you-know-what.."

"Ah, well, the Darling half of her wanted to explore the campus a bit. She got in a call with me over comms, you know how it are. Pets are very clingy!~" Mira chuckled.

"She's not a pet anymore, is she thought...?" Rachel grimaced. "Old habits die hard?"

"Something like that." Mira shrugged. "She hasn't taken to class lectures like she used to, so she said she'd do more studying at home. She gets too stir-crazy when she sits in one place for too long. She also got a perfect score on her latest test, did you hear?"

"I... didn't." Rachel blinked.

"Oh, Dahlia was so pleased with herself. Of course, I had to give a treat to such a smart girl..." Mira toyed with herlong red  hair. "Anyway, after class, can I pull you aside for some more experiments?"

"Like... what?" Rachel blinked. "I barely had time to break in the new suit you got me. I was gonna do some basketball in the quad..."

"Ohhhh I'm not sure that'd be such a good idea." Mira shook her head. "Basketball's a very physical sport, yes? You'd probably kill someone with just a shove with enough pressure at the right spot!~"

"I-I would not!" Rachel blustered. "That'd be a freak accident! I'm more coordinated than that..."

"Not to mention if someone booped this little button here... boop!~"

Mira pressed a finger to approximately where Rachel's navel was, triggering the massaging mechanism her biometric suit contained. Her entire body began to vibrate and shudder, concentrating around her nether regions in waves. Her cheeks went flush as her hands immediately surged downwards towards her crotch, her hips rocking on their own.

"Awawawa turnitoffturnitoffffffffff...!" Rachel wheezed, wincing as her body tensed and relaxed all over, searching for release. Mira pressed again, and the process ceased.

"So we'll do more labs at the usual place?" Mira nodded. "Don't find me, I'll get you, okay? Now, rest up! Here's the completed group-work Mr. Flik asked for."

Mira presented a small binder, sliding it over to Rachel; Rachel studied it, admiring the curious chrome finish...

"Sh-shouldn't I be working on the assignments anyway?" Rachel grimaced. "I feel like I should be learning more things at university, but-"

"You, honey, are soon to be the greatest producer of space rubber within five hundred million light years!" Mira slapped Rachel's back with merriment (Rachel's body squeaked in response, like a rubber chew toy). "You won't need an education after that, you can retire!~"

"Um... well I guess I do have some things to pay off." Rachel fidgeted in her seat.

"Great! Now, act natural! Pretend I'm not here!" Mira rested her head on her hands. "Just don't think about me observing your behaviour naturally in the wild!~"

"...Well, not thinking's what I do best, ehehe..." Rachel rubbed her neck; was Mira always gonna be such a goof-off in class? She supposed Mira already knew everything, but surely it had to be distracting...
