"I do have one question before we start experimenting," Laura said, "Well, two questions actually."
"Go ahead," answered Jen, rolling the pill between her thumb and finger.
"One, can you make more of those pills at will? Say, by forcing yourself to cough. Or is it only on the hour?"
"Didn't try it, for obvious reasons, but let's see..." Jen placed her other hand over her mouth and forced out a cough. Feeling something hard and dry hit her palm, she removed her hand to look at the next white pill that had landed on it. "Yep, seems to be a limitless supply."
"Alright, cool, two," Laura continued before the sound of the bathroom door being opened distracted the three. They stopped talking out loud, continuing their conversation silently in their mind.
'Huh, so it's Rachel,' Jen thought recognizing one of the gabbing voices as one of her fellow cheerleaders. 'And...'
'Liz,' Audrey answered, feeling the lesbian's tongue enter her.
'Targets acquired,' Laura thought in a tone not unlike a supervillain.
Rachel's tall stature was in sharp contrast to Liz's, if the latter's gothic aesthetic didn't already set their appearances worlds apart. Rachel's hoodie and jeans versus Liz's black dress and leather boots would make anyone surprised that these girls tolerated each other at all, let alone were best friends. The new pair glanced at the mind-linked trio offhandedly, but paid little attention to them besides a small wave of the hand as they headed into a pair of stalls, Liz's tongue curving under the door to stay extended and inside Audrey. Seeing this as a perfect opportunity, Laura covertly swiped a pill from Jen's hand and placed it on Liz's tongue, letting it dissolve in the saliva.
'Hey,' Jen shot, 'ask first.'
'Sorry, too curious,' was Laura's only reply. The pill disappeared on Liz's tongue and began to affect her out of sight. 'Now, how do we get it to affect Rachel?'
'The only way I know how is to offer a drink,' Jen replied, 'which would be awkward outside of class.'
'Jen,' Audrey thought, 'Don't you still have an afflicted spray bottle from earlier?'
'Oh shit, yeah I do.' She pulled it out of her purse. 'But it'd be kind of rude to just spritz her.'
'I'll do it,' Laura added, offering to take it from Jen's hand, 'Not like I've got any social status to lose.'
A few minutes passed, the trio watching the stalls intently as the pair inside gossiped wildly. Eventually, they heard a couple of flushes and the pair came out. Liz maintained her usual strut, unaware of the change that had affected her: Her arms were gone, no trace, not even armholes in her dress, that she had ever had any. She was not without dexterity, though, as her twintails seemed not only longer, but completely prehensile as well. Whereas Rachel washed her hands, Liz washed her hair, no longer dyed black-with-purple-highlights, but actually being naturally colored that way. Her boobs seemed a few cups bigger too, which given they were decent DDs before was impressive.
"Hey, Rach'," Laura said, coming up behind the tall, athletic girl.
"Hey Laura," Rachel responded, a much less negative response than she would've given in the reality where the scientist was *not* a friend of Jen's.
"You mind being a test subject for a second? I've got this new spray I'm developing and I need to check for side effects. It'll only feel like water, don't worry."
"Eh, sure," Rachel said while drying off her hands. "What's it supposed to do?"
"It's in the early stages, I can't reveal too much," Laura answered, taking aim as Rachel spread out her arms. "But I think it should help you with your cheering regiment." With that, she spritzed a couple times, waiting for the effects on Rachel to take place.
The effects were nearly instantaneous. Rachel's bust grew a few sizes, becoming about as large as Liz's. Furthermore, a hole opened up in the front of her sweater to reveal her generous cleavage. Her appendages then began shaking, her head and arms each doubling in number, and a third leg growing from beneath. Her clothes conformed to the new anatomy in the same moment, and her body finally settled down.
"If that's the case," Rachel's left head commented, as if nothing significant had just occurred, "Why didn't you just use Jen?" Reaching her upper right arm in between her breasts, she dug around as if searching for something... the others noticed her purse had disappeared... before pulling out her pocket compact mirror. Flipping it open, she began examining her reflection one head at a time. Jen's... well, technically Audrey's and Laura's... new memories told them that Rachel's cleavage was larger on the inside. *Much* larger. Large enough that it could function as several families' house if she ever decided to rent space inside it out. And she (or anyone else with her permission) could reach inside and pull any of it out whenever she wanted.
Laura quickly deduced an excuse. "Of course I did. You think these get through development with just one field test?"
Liz spoke up next. "You've got, what, a hundred bodies? Why not use your own?" she offered, placing her hair-arms on her hips.
"Hence *field* test!" Laura countered, "And it's ninety-three at the moment, I'll have you know. Soon to be ninety-five."
"Close enough," Liz apathetically replied, her and Rachel heading for the door. Once out of earshot (and tongueshot), the mind-linked trio began talking again.
"That was cool!" Audrey exclaimed, high-fiving the other two.
"Excellent results! Wish I could've sprayed them a second time."
"Heh, I am actually starting to like this now," Jen admitted, "How much time left for lunch?" Her mind received a vision of the cafeteria clock, no doubt the viewpoint of one of Laura's clones. "Oh, half an hour? We've got plenty of time to mess around."
"Alright, what's next?" Audrey asked.
