To own the magic amulet.

"I wish this magic amulet was mine!" Lidia yelled out in a surprisingly clear voice.

I desperately pushed Lidia off my lap, hoping to separate her from the source of my power before it was too late. But, I was.

I watched in horror as Lidia pushed her small, diapered frame off the floor and smiled at me in victory. The amulet was clearly dangling from her neck.

I reach between my breasts that are still dripping milk, hoping that what I was seeing was an illusion. However, we I grope for my salvation, all my fingers are greeted with is air.

"Oh, no? Did Baby Sarah lose her toy?" Lidia said, her tone deep with malevolent sarcasm. "I wish that Sarah and I both had our normal bodies."

"No!" I yell out as I feel my body begin to shrink. I can feel my tight fitting clothes rolling off my body as my perfect, Mommy Dom frame shrinks back to that of the timid woman I was months ago. My chest feels lighter as my breasts deflate. My vantage point lowers as my body and legs shrink back down to my original height of 5'2".

As I am feeling myself shrink, at the same time, I am watching Lidia's body grow drastically. I watch as Lidia's breasts swell back up to a respectful size. Her hips grow, stretching the small onesie she is in and the tapes of her messy diaper to the max. She also gets taller and fitter. The snaps at the crotch of her onesie snap open almost comically as her torso lengthens, making the clothes she is wearing too small.

Looking up at Lidia from my vantage point on the couch, for the first time since the world became my playground, I suddenly feel small and defenseless. I know, in the pit of my stomach, I am at the whim of the 5'11" beautiful woman who is standing in front of me wearing nothing but a too small onesie and messy diaper. I think deeply into the couch, gripping at the pool of clothes to preserve some modesty and hide my small frame.

"Well there's the Baby Sarah that I know and love! Wants wrong little girl? Are you afraid of your big, bad babysitter Lidia?" Lidia asks in a mocking tone. "Is that because you used your magic to **** me to sign my life away to you?" Lidia continued, slowly stalking forwards to me.

"Is it because you **** me to wear stupid baby clothes?" Lidia growled as she whipped the onesie she was wearing over her head and threw it over my face. I tossed it to the side to reveal Lidia standing even closer to me, naked except for the necklace with the ruby necklace dangling between her breasts and her shitting diaper, with it's tapes stretched to their capacity, given Lidia's new larger body.

"Or is because your **** me to sit around in a poopy diaper for hours on end?" Lidia asked, getting even closer to me and gesturing to the shit filled diaper barely clinging to her waist.

Looking at Lidia's bare breasts and the ruby pendant dangling in her cleavage, I knew I had to take this opportunity to get my power back. I suddenly lunged at Lidia with all of my might, desperately groping for the magic necklace with my hands. However, in my smaller, weakened state, I couldn't overcome Lidia's newly returned strength.

"Naughty baby! Trying you use my tricks against me? Not today, sweetheart.". Just like when I was a teenager, Lidia easily manhandled me, grabbing me by the wrist and throwing me to the ground. While laying on the ground helplessly, I looked up only to be greeted by the sight of Lidia's diaper, on the verge of a blowout, slowly lowering onto my face.

"I think Baby Sarah needs a punishment for that. You seemed to like my poopy diapers so much when I was in charge, maybe you'll like a face full of one now!" Lidia said manically as she firmly pressed her poop filled diaper into my face.

As much as I struggled, I couldn't get free. The stench filled my nostrils, and I started to gag.

"Please, stop," I pleaded between dry heaves. Lidia's only response was a remorseless laugh. That was, until she pinched the amulet between her fingers again and made her next wish.
