Kim awoke slowly, disoriented. Her head hurt, and her eyes felt heavy. Her mouth was dry, and tasted awful. She was sitting in a chair, and her neck was sore from having her head rolled back while she was asleep. She forced her eyes open, squinting against the light. She was staring up at the ceiling of what she slowly recognized was her master bath. Painfully, she lifted her head up to look forward.
Kim was stunned to find herself looking at herself, soaking in the bathtub. The her in the bath tub noticed Kim stirring and looked over. “Finally waking up, princess?” the tub version of her asked.
The tub girl's voice brought it all back to Kim. The abduction in the garage by the doppelganger claiming to be her twin sister. Having that gun, fake as it may have been, shoved in her face. Being drug around her own home, bound and gagged, and having her captor discover her secret nursery. Having her sister strip her and start diapering her, and her escape attempt, culminating with her knocking herself out on the floor.
“You with us, Kimmie?” Angela asked, snapping her fingers.
It snapped Kim back to reality, and she attempted to rise, to speak, finding herself unable to do either. She looked down at herself, eyes wide in shock as she discovered that she was wearing nothing but a diaper, and a belt of silver duct tape around her tummy holding her firmly to the chair. She was sitting on a black, wheeled office chair, and though she couldn't them, she could tell that her legs had been bound to the center column under the chair, and her arms tied together behind the chair's back. As she tried to reach out, she found her hands trapped in tight fists. Her lips were once again sealed shut with tape, this time with something stuffed in her mouth first.
“Mmmrgh unnnff hmph!” Kim screamed into her gag, thrashing against her bonds. The chair shook, each jerk she made causing it to roll slightly back forth across the marbled tile.
Angela watched her sister's spasm with a thin smile, leaning back into the tub, picking back up the ice pack she had been holding against her head with one hand, and taking another sip of the wine she'd liberated from the wine cellar straight from the bottle with the other. She'd never drank anything older than she was before.
After getting rid of the neighbor, Angela had returned to find Kim exactly as she had left her, knocked out on the couch. She'd managed to carry Kim back upstairs to the nursery, and laid her out on the changing table once again. A vindictive part of her had wanted to wait for her sister to awaken before diapering her, but she'd decided to be practical instead.
So she had finished untaping the unconscious girl and stripped her of her shirt and bra. Again no piercings or tattoos she would have to mimic, but Angela was disappointed to see how much more endowed her sister was than she. With clothes on, the difference was negligible, but anyone comparing the twins naked or even in a bikini would be able to tell the difference. At least they were real. She was lucky Kim hadn't spent her fortune on plastic surgery.
She retrieved the diaper that had fallen to the floor in the scuffle, eying the baby powder that was spilled all over the carpet. Her eyes still stung and the odd, sweet but chalky aftertaste of it lingered in her mouth. She decided against using the baby powder, the bitch deserved a rash after throwing that powder in her face.
Angela had done some babysitting back in high school, before one of the parents found out she'd been stealing things from the houses. She was no stranger to diaper changes, but there was something different, a feeling of power that came with taping her unconscious sister into the babyish garment. She again regretted not waiting til Kim was awake, but she would be awake for plenty more, and right then, she had other things to do.
With her sister finally stripped and diapered up, she began contemplating her next move. She had to restrain her so as to avoid a repeat of the last fiasco. Angela entertained the idea of tieing her up in the crib, but it was barely nine o'clock and she having Kim mobile would make it easier. Hobbling her and having her shuffle around seemed risky, but then she remembered a home office with one of the wheeled desk chairs, and raced to go get it.
Angela eased her diapered sister into the chair, and then proceeded to tie her up. She went a little nuts with the duct tape, not wanting to take any chances. She balled Kim's hands into fists and then wrapped them with tape, ensuring that even if she go loose her hands would be useless. Then she belted her to the chair with a few passes before pulling her arms behind the chair and wrapping them from wrist to elbow in silver tape. To keep her from trying to stand or scooting herself around, her legs were pulled back to the column holding the chair and securely taped in place.
The ripping of duct tape had done nothing good for the headache she was rocking from when she fell, and her shin was throbbing from the kick her sister had landed. Feeling particularly vengeful, Angela picked up Kim's soiled panties from the floor. The fabric was still damp, and even at arm's length Angela caught a whiff of urine. She balled up the fabric, and careful not to push them too far towards the back of unconscious girl's throat, stuffed them into her sister's open mouth. She negotiated the fabric into each of Kim's cheeks until she could shut her mouth, making the girl look like a hamster. Then she pinched her lips shut and sealed them with tape, proceeding to wrap the tape three times around her sister's head, under her hair.
Satisfied that Kim wasn't going anywhere when she woke up, Angela sought pain killers. She found some aspirin and grabbed an ice pack from the freezer, and then ventured into the basement, where she located the wine cellar. She figured she had earned herself a relaxing evening in the tub, with some super expensive wine, completely unaware that this was exactly how her sister had planned to spend her own evening before Angela had arrived to hi-jack her life.
She started to run a bath while she went and wheeled her still unconscious sister into the bathroom. Angela was beginning to wonder if she should start to worry, but as soon as she sank into the hot bath, all worries were erased as she soaked in her own bliss.
She glanced over at her captive, the pampered princess who's throne Angela was now sitting atop. She ripped the cork from the wine with her teeth, sinking lower into the tub as she brought the bottle to her lips. Her other hand slipped into the water, finding that familiar spot between her legs.
It was almost an hour later when Angela heard her sister coming around. “Finally waking up, princess?” she asked, watching as Kim slowly put the pieces together again. “You with us, Kimmie?” she said, snapping her fingers, sending Kim into a frenzy. Angela became briefly worried the chair would tip over as Kim tested her bonds, but the chair only rolled around slightly, it's widely split, five wheeled base proving more than adequate job for holding the struggling blonde.
Finally, Kim gave up her futile struggles, leaning as far forward as her bonds would let her, her nostrils flaring as she caught her breath, glaring daggers at her sister.
Angela set the ice pack and wine bottle down, and slowly stood up.
Kim felt her rage deflate like a balloon. The tub gave Kim another few inches, and standing there, hands on her hips, naked, water dripping off of her smooth skin, she looked like some goddess rising from the ocean. Kim felt suddenly very small, sitting there, completely helpless, muted and wearing nothing but a diaper, while this toned, fit version of herself stood over her. Even Angela's neatly trimmed bush, sitting right at Kim's eye level, seemed to scream woman and declare her superiority over the diapered Kim.
Angela could see her position had made the desired effect. She let it sink in a moment longer, before folding her arms across her chest. “Let's get a few things straight. Right now, I own you. For the next few weeks, you belong to me. But if you play it smart, and cooperate, these next few weeks don't have to be that bad for you. You can spend all your time locked up in your nursery, living out whatever bizarre fantasy or fetishes you've got going on, while I see what's it's like to be you. The life that could have just as easily been mine.
“Then, when I've gotten a taste of what my life could have been, once I've seen what I've been denied, I'll take my half of the inheritance from dad. And I'm not even gonna be greedy and take a full half. You still get you're sweet mansion, your kushy job, your cars. Well, I may take one of your cars, but I'm just taking half of the money that's left. Not that unreasonable, considering I'm your twin sister, and I got nothing. But then I'll be gone, out of your life forever. You can go back to your life, a little bit poorer, but I doubt you'll even feel it. These few weeks will just be a bad memory.
“Now, I'm not going to hold your little escape attempt against you. It's only natural. And I did pretend to shoot you in the face, which was kind of fucked up, but it let you know that I'm not going to kill you. But that doesn't mean I won't make your life a living hell. You made your shot, and you failed. I won, and I will always win. Know that.” Angela let her words sink in. Kim couldn't bring herself to look at her. Looking up at her just made her feel small. Looking straight ahead she found herself staring right at her sister's crotch. So she stared down at the floor before the tub, struggling not to cry.
“Now, you have a choice. Cooperate, and this won't be that bad. Look at it like an expensive vacation. No work, no responsibilities, just help me pass for you when I need it, and sit around in you diapers like the baby you so clearly want to be. Or you can be uncooperative, and you'll wish I had shot you in the face. So, what's it gonna be?”
Kim finally looked up at her sister. The anger that she had felt when she first woke up, so easily wilted under her captor's imposing gaze, had been slowly building back up. It wasn't her fault their parents had split up and separated them. She didn't chose to go with her rich dad and not her broke mom. And while yes, she did occasional like to wear diapers and regress, she by no means saw spending a few weeks locked in her crib and forced to use her diapers as a “vacation”. She wasn't going to help the woman who had kidnapped and was holding her prisoner in her own home impersonate her and steal her money.
“Fffmmph ooooo,” she said deliberately, trying to be as coherent as possible behind her gag. She needn't have bothered, her eyes said fuck you just fine all by themselves.
Angela laughed, sliding back down into the tub, grabbing her wine and taking a swig. “Suit yourself. By the way. How do your piss soaked panties taste?”
The fit Kim began throwing at the realization of what was stuffed into her mouth put her first tantrum to shame. Angela grinned, sliding deeper into the tub, her sister's muffled screams and the squeak of the chair was music to her ears.
