CYOA: The Twins: The Other Side - Chapter 7 (Story) (Patreon)

"It's only natural," Emily smirked. "Besides, it's your new favorite thing."

"No, it isn't!" Natalie turned bright red, her face burning at the insinuation, as if she would have done what she had on the rocking horse if she'd had any other choice. "Emmy, please... I just got changed!"

"Last night," Emily said, as if her sister needed a reminder. "I know it might not feel that way, since I'm sure you slept through the night like a good little girl, but that's been a while now."

"That doesn't count!" Natalie sulked. Even as early as she'd woken up, it didn't feel like very long at all since she'd escaped that icky, mushy feeling... Emily couldn't seriously want her to do it all over again so soon!

Emily sighed, kneeling down in front of her shrunken twin. "I doubt anybody's going to look at you twice," she told her, "not in that get-up... But if they can see that you've used your diaper, they really won't. There will be no reason for them to think you're anything more than you appear to be: just a silly, pants-pooping little baby. And isn't that what you want them to think?"

It wasn't, to be honest... She wanted them to suspect something was up, to look closer so that she could hopefully convince them to help her. She knew Emily was right, however; if she was toddling around in a dirty diaper, it was going to be far harder for her to convince them of her true identity, and that she wasn't simply a little with an overactive imagination.

"I-I don't know if I can go again already," she lied, praying her tummy wouldn't rumble too loudly and prove how big of a lie that was.

Emily chuckled, straightening back up. "Aww, is that what you're worried about? Fear not, Nat... I have plenty more suppositories I can give you to help out with that." Natalie's eyes widened, her head shaking. She should have known Emily would have more of those cursed things... "That's what I thought," her sister said. "Now, I'm going to go get ready, and if your pants aren't full by the time I finish..."

She let the end of her sentence trail off, no need to repeat the threat when she could tell, by the look in Natalie's eyes, that it was still forefront in her mind. She picked her up, setting her back in the pop-up crib, it serving just as well as a playpen.

Natalie watched Emily leave, whimpering, the choice in front of her almost unthinkable... A day earlier, it never would have crossed her mind that, in less than twenty-four hours, she'd have to decide whether it was better to intentionally poop herself, or to let her sister force her to do it, for the second time.

"Emmy!" she bounced in place, pleading pitifully. "Please, don't..."

To her surprise, Emily stopped, paused with her back turned to her. Was she thinking about it? Had she recognized how cruel she was being, and had second thoughts?

"A messy diaper will be good," she mused, "but I'm not sure that's enough..." She walked over to her desk, rummaging through it.

"Wh-What are you doing?" Natalie asked nervously, wishing she'd kept quiet now, bracing herself for the worst as she attempted to get a glimpse, so she could prepare herself. Between the inflatable bars of the crib, and Emily's back, it was impossible to tell what was going on, although she could see Emily was gathering a couple different things. The longer it took, the more it worried the tiny scientist, and, considering how scared she'd been at the start, that was quite the feat.

She still couldn't tell when Emily turned around, keeping her peering through the bars with morbid curiosity as the woman approached. The first thing she did was spin Natalie around, tugging out the rear waistband of her diaper. "Didn't think so," she sighed, turning the girl back around. "You know, just because I'm going to give you a suppository doesn't mean you get another ride on the horsie."

Natalie's face went red again, as, flustered, she insisted, "N-No, that's not...! I-I don't...!"

"Maybe when we get home, if you do well," Emily patted her on the head. "For now, though..."

She reached forward, Natalie flinching, not knowing what sinister plans Emily had for her face. It made sense that was what she wanted to change... She might have been able to fool her bimbo neighbor, but would Natalie's co-workers really fall for the same story, that Emily - or, rather, 'Natalie' - had adopted a little simply because they looked similar? What was she possibly going to do to counter-act that?!

In the end, it was a huge relief when Emily's hand moved to her mouth, and popped in a pacifier. She didn't see how that would solve Emily's problem, but that was fine with her... And, while she wouldn't admit it, there was something comforting about it. Without thinking, going purely off of the instincts that had already been building up over only the previous evening, she started to suck on it, expecting the same soothing sensation that she knew it could bring to her.

She got that... But that wasn't all. With it came a sweet taste, one that was overpowering, artificial, like the sort of candy-like candy that only small children and littles could tolerate. It probably was meant to taste like something specific, though all she was getting out of it was sugar. She wrinkled her nose, yet, before she could try to spit it out, Emily locked it in place, the sweetness growing more intense as the bulb expanded, touching every part of her mouth.

"Much better," Emily nodded. "Now, be a good girl and get working on those diapers!"

Emily gave the seat of them a swat as she walked away, leaving a sister who couldn't even stick her tongue out at her back in response, thanks to the paci. Natalie grumbled, giving the bars of the crib another shake, hoping they might have lost a bit of air overnight, that she could perhaps push them apart far enough to slip out. 

They didn't, and, the same as last night, she couldn't spot anything to poke a hole in the crib with that she could get her hands on. She was trapped, and, unless some miracle happened, she was going to be messing her diaper once more, one way or the other, in a matter of minutes.

She thought back to last night, to the suppository, how helpless it had made her feel... It was hard to divorce it entirely from what else had been going on, the memory of which made her blush and squirm, but she could isolate enough of it to know that she didn't really want to go through that again if she could help it.

Which meant... She sighed, staring down at herself, at the tiny, pink t-shirt, the huge, puffy diaper... How could it possibly have come to this, and in such a short span of time? She did her best to push those thoughts aside, to not think about her normal daily routine, how normally she'd be taking a shower about now, how she'd probably sit on the toilet afterwards, if she hadn't done it first, never knowing how lucky she was to be able to do that...

She squatted down, closing her eyes, pretending she was in a bathroom, not the middle of her sister's office, and that she had her panties pulled down. No, of course she wasn't wearing a diaper, no matter how warm and sweaty her bottom was, or how far apart her legs were being forced, how loud the crinkling was whenever she moved... It was quite the feat for her imagination, and, to be honest, as someone who spent most of her time in a lab, dealing with theories and facts, her imagination was already not in the strongest shape.

"Come on," she mumbled past her pacifier, hating herself for being so eager to do this... Considering the alternative, however, how could she not be? "Just go..."

Finally, her face red, her forehead damp with sweat, her years of potty training cracked. Something warm, and thick, and squishy started to ooze out into her pants, the diaper crackling, a lump forming in the rear. And then, as soon as her body felt that, it clammed up once more, realizing that it wasn't on a toilet after all, that her brain had been lying to it.

"No!" she groaned, stomping her foot. It had been so easy last night... Of course, it had been totally out of her control last night, her bowels having no choice. She'd held out until she couldn't anymore... As full as her belly was this morning, she was nowhere near that desperate.

Nevertheless, she was still going to have to do this, or she'd be going through that all over again. She bent her knees further, letting her padded backside sink closer to the floor, bearing down, the sweet taste in her pacifier squirting out faster as she clenched her teeth around it. 

The lump began to grow, and this time, Natalie refused to listen to her instincts, kept pushing, feeling the slow, steady progress of her diaper ballooning behind her, having to work and strain for every bit of it, fighting everything she knew about potty training the whole time.

In the end, she wasn't so sure if this had been the right choice. The suppository was more invasive, and gave over more control to her sister... But it was so much easier, and, in her mind, she could blame it all on Emily. Now, even if she knew she hadn't really had a choice, ultimately, there was no denying that she'd done it on purpose.

"Well, well, well," Emily snapped her out of her pity party. "That was quite the show."

Natalie gasped, standing up straight, her diaper drooping heavily between her legs, leaving no doubt what she'd done in it, even to someone who managed to avoid smelling it. How much of that humiliating display had she been doing with an audience?! Emily unlocked the pacifier, taking it out of her sister's mouth, letting her ask, "How wong wewe you standing thewe?"

Emily giggled as Natalie's hand shot to her mouth, aghast. Her voice was already higher, thanks to being small, but it sounded even more-so now, more childish, especially with that unexpected lisp. "Emiwy!" she gasped, her tongue refusing to work correctly, no matter how hard she tried. "What did you do to me?!"

"It's the finishing touch of your disguise," Emily told her. "As much as I'd love to keep your pacifier in the whole time, I might need you to tell me how to do something, and somebody might overhear you talking, or they might just want to hear the cute baby say 'hello' back... So, you needed an adorable, and completely believable, lisp. Isn't it precious?"

"No!" Natalie glared up at her. "Emiwy, this isn't...!"

Before she could finish, the paci was back in place. "For now, though, we'll let that drug sink in a little more... Wouldn't want it to wear off at the wrong moment." She winked, scooping Natalie out of the crib, one hand on her bottom, squelching the contents of the diaper. When Natalie whined, she gave her a bounce. "You did a very good job, sweetie," she complimented her. "What do you think about my disguise? I wore the most boring thing I had in my closet... I think it captures your style pretty well."

Natalie sulked silently, although Emily didn't seem to mind... If she'd actually wanted her sister's opinion, she would have asked for it before giving her the pacifier. She carried Natalie out of the apartment, the girl clinging tighter to her as they walked out into public, her full diaper on display, and to her car, where Natalie saw something she'd nearly forgotten about.

She shook her head, blushing, as Emily slid her into the car seat, fastening her in nice and snug, the straps tight around her diaper. Natalie wanted to think there wouldn't be a repeat of the night before, that she couldn't possibly get so turned on again by the way the strap rubbed against her diaper, now that it was messy... But she knew that was more wishful thinking than anything. It was already bad enough the last two times she'd gotten off were in a diaper, once mere moments before she pooped her pants... And that they'd been some of most intense orgasms of her life. She was almost scared of how it might feel now... That, somehow, it might be even better.

It was definitely the memories of the rocking horse that made her so wet, so quickly, barely out of the parking garage before it was a struggle to keep from obvious grinding against the straps, or giving her diaper a rub herself. There was no way it was connected at all to her current situation... She was very grateful for the pacifier, however, even if it was making her lips, to help hide her frustrated moans as she writhed in her car seat.

She was having a hard time concentrating when they pulled into the lab's parking lot, though she had to pull it together when her pacifier was taken away. "All right," Emily said, turning around in her seat to face her. "It's showtime... Now, before we go in, is there anything I need to know about?"

Natalie squirmed, her head swimming. What should she say? She knew there was a fingerprint reader at the door that was going to give Emily trouble... Then again, it gave everyone else trouble from time to time, too, so, as long as it was somebody they knew, the security guards would usually over-ride that anyway. If she could find a way to make them realize the 'Natalie' who was using her ID card wasn't really her, perhaps she could stop Emily's plan before they even got in the door.

But... How was she going to do that? With the pacifier in her mouth, it would be awfully hard to say anything, and, even without it, she sounded like a baby now... And there was almost no chance she'd be able to talk to the guards without Emily being right there, watching, ready to laugh off anything she said as the ramblings of a silly little girl playing pretend.

There might be more opportunities inside the lab for her to talk to one of her colleagues privately. Probably not for long, and her 'disguise' was going to make it much more tough to convince them of her true identity, not to mention embarrassing, but there was a chance.

Or... Would it be better to forget about that, and do what Emily wanted? Could she really face anyone else here like this, after everything that had happened to her, that she'd done, and risk having to tell them all about it? No matter how incredible her discovery was, there was no way they'd be able to respect her ever again... If they didn't get greedy and take the credit for themselves, leaving her to languish in her sister's care. After all, who would believe her, as she was now, over anyone else who worked there?

"Well, Natalie?" Emily asked. "I'm waiting."

Natalie sighed, trying to think straight, to weigh her options. What was she going to do?!

Should she...

Stay quiet about the fingerprint reader, and try to get the security guards' help?

Tell Emily about the fingerprint reader, then try to find another scientist to help her?

Or cooperate fully with Emily, to try to get out of there before anyone recognizes her?
