Calibrate the machines and your control

You wake up, stretching out from a lovely rest. You still had a much larger set of pajamas wrapped around you, and you glanced down at the larger form. You could get used to seeing yourself with a body like that... but, not yet. You still had a lot to learn about what Ela could do, but you wanted to continue working on your control of her body, primarily, because that interested you more. Having a beautiful girl that would occasionally behave exactly like your innermost thoughts, if you pushed a little harder...

You reached down, lightly rubbing the large breasts through the fabric, still amazed that you were feeling solid breasts seemingly existed within the fabric, despite knowing there was a definite air gap between this chest and your more modest form. Your light and gentle squeezes encourage Ela to let out a sleepy moan, as she started to wake up. "Oh, Emily, good morning..! That is far more pleasant than alarm clock noises. You may have to wake me up every day like this..."

You smiled, sitting up, forcing Ela's form to follow along, large chest jiggling enough that you could feel the tug of the pajamas on your shoulders. You enjoyed that immensely, but would have to pick things up later. "Ela, do you mind if I go take a shower? I think we've got some work to do, and I'd like to feel clean. ...I actually feel pretty good but the shower helps."

"Okay, no problem. I want to do some work with the lab equipment today, Zoe had trained me on some of the things like the microscopes and she said I should practice before I get my own lab tasks, but I couldn't really do that on my own until recently anyway. You can show me some more of the machines later too!" Without much warning, Ela seemed to just walk right off of you--her fabric briefly split, and re-formed the moment she was in front of you. You blushed as you were suddenly naked in the bedroom, but Ela kept walking, her fabric rear swaying back and forth as she happily headed out into the lab space to tinker.

You stepped into the bathroom, to quickly wash off in the shower. The whole space was barely used--remembering that Ela was essentially silly putty brought to life, you weren't sure really what purpose a normal bathroom might serve for her. When you had silly putty as a kid, cleaning it was an impossibility the moment it fell on the floor and picked up some cat hair. You assumed Ela had some better way to clean herself, but also you didn't really know if things could get 'stuck' in her. In any case, you quickly showered, toweled off, and hurried back to the bedroom to find your clothes from yesterday, which were clean enough to deal with for now.

As you stepped out and headed into the lab area, you saw Ela peering deep into a microscope. She was dressed up much like Chloe might have been, wearing a long lab coat and some other rather conservative clothes underneath, like a sweater and some slacks. With no Zoe or Chloe around, you had an opportunity to really test your control of Ela without feeling awkward about it. You know Zoe said to do whatever you like with Ela even while they were present, but that didn't change the fact that you preferred some true one-on-one time with Ela right now.

You thought hard as Ela continued to stare into the microscope, and her hips began to swing back and forth lightly. You were planning to see just how much you could build up over time, to see how Ela responds, or if she even notices. So far, she's treated everything you'd implanted into her as a normal behavior unless it was clearly contradictory to something she wanted to do, but you wanted to see in particular what the tipping point into awareness might be. While you thought, you decided to strike up conversation, to distract Ela from what you were planning.

"So, Ela... the research that Chloe talked about yesterday. She mentioned the next iteration of elastomer, and making you a 'sister'. What exactly is our aim going to be, specifically?"

Ela began to tug her jacket off, setting it down on the chair nearby before returning to the microscope. "Getting a little warm in here... oh, yes. Our primary goal is to understand if there is a change to the elastomer molecules or the neural cluster components that would allow the brain connections to stay active. Like they said yesterday, movement and shapeshifting disrupted my ability to think and process abstract thought effectively." Ela's hips were beyond swaying now, swirling hypnotically back and forth before her ass bounced up and down. All your thoughts that you sent into her head were so subtle, you wanted to see how she interpreted concepts like 'shake your ass around', and you were definitely not disappointed.

"That must've been really tough, not having the ability to easily communicate or act on your knowledge."

Ela nodded, standing upright, flipping her hair back as she removed her sweater swiftly. Ela turned around, in just her bra and pants, and her hips still bounced back and forth, but her face was still somewhat serious--not sad, just matter-of-fact. "It was challenging. The only way I could really describe it is that time felt like it fluctuated relative to how hard I thought. Simple things, like waving a hand in response to a greeting, everything moved at normal speed. Trying to speak, however, it was like time sped up while I searched for even just a word, and by the time it came to me, the conversation had already advanced three topics. But not just that--there was no wanting. I was always the 'reaction'. Only ever a response to stimulus, never the catalyst."

You nodded, watching as Ela removed her bra next, also at your mental command. Her shoulders swayed left and right, allowing her sizable breasts to bounce and jiggle wonderfully to some rhythm only she could hear, but she still didn't notice anything, her face still just locked on you with her friendly gaze. You cleared your throat after a little bit of squirming, excited by the suggestions you could implant in Ela, before you continued with the conversation. "If we make this 'sister' of yours, what does that mean for you? Like, could you upgrade your elastomer if that's what fixes everything?"

Ela strutted toward you, her breasts swaying and bouncing as she did. You gulped, seated in a chair next to another one of the microscope stations. "I was going to check that sample right now in fact! It's in the station behind you, don't mind me but I'm coming through." You normally would have moved out of the way, but you had a different thought--for Ela to just use the chair even though you were still on it! Ela climbed onto the chair, compensating for the fact that someone was already in it, sitting in your lap and pressing her large breasts against your face as she leaned over the back of the chair, reaching to the microscope. Despite the odd positioning, Ela still got to work like nothing was out of the ordinary, even as you brought your hands up to squeeze Ela's breasts against your face.

"Oh, I suppose I could over time replace my elastomer molecules, and maybe it would be wise to do. But, I don't intend to remove any nanites if I do 'cure' myself, I feel... content, with a connection like I have to you. I wouldn't wish for a sister of mine to be dependent on another being, but for me?" She smiled down at you, even though your face was buried in her breasts, and she didn't even give that a second thought. "I only want to stay connected to you, Emily. I want nothing more than this closeness, and to do whatever I can to make you happy. You've already done so much for me just by agreeing to participate in this experiment."

You nodded a little, nuzzling Ela's breasts. You should maybe feel bad for taking advantage of Ela's body while she was telling you heartwarming confessions, but this was part of the plan! Not only does Ela like the connection, she clearly enjoys being controlled, having your thoughts implanted into hers to masquerade as her own original thought. There must be more you could do with and to her, she would no doubt agree to any of your suggestions. But for now, you just enjoyed the fact that her body was accessible to you and it didn't bother her in the least. You hugged your arms around Ela's waist, and she smiled, though to her it was just a normal hug.

"I think the more interesting implications of the research is what Zoe and Chloe would use it for," Ela said, glancing down again at you. You muffled a 'huh?' into her chest, prompting her to elaborate. "Once a fully independent elastomer being is created, both Zoe and Chloe wish to try to become elastomer themselves. Each have their own particular shortcomings that are solved by my particular composition, but more importantly to them, I am not dependent on another body for energy--just, uh, brainpower in our specific case. This might start a whole revolution of new elastomer beings! They could be made in the lab, converted from bodysuits and slime people, possibly even humans could convert into my particular species. Having a small army of shapeshifters roaming around would be quite a sight, I think."

You nodded, and pulled your head away from Ela's chest. "I'll help however I can, but I just know how to work the machines, it'll be up to you and the other doctors to really know where to take things. You may be borrowing part of my brain, but it seems like you're the one with the hyper-advanced knowledge. It makes it a bit ironic that you're not the one who can make me do things..."

Ela scooted off your lap, stretching out. "I don't mind! Make me do anything, everything. I want your involvement in my body and actions more than anything else I might do! For now, though, could you help me with one of these oscilloscopes so I can see how it works?"

You grinned. "Only if I can involve myself in your body and actions in some fun way while we did it!" Ela grinned in kind, still not even realizing she was topless by your design, but plenty willing to be even if she consciously acknowledged it was unusual.
