What else is a magically perverted twin going to do

“Alright little bro, stay right there and don’t move until I say so.” your sister said, positioning you in the middle of your family’s living room.

You didn't correct her error in saying that you were the "little" one (even if you physically were).

I guess I’m not going to school today…

Caris plopped down in the center of the long sofa, phone in hand, continuing to shuffle through the options available, in prime position to snap even more pics of your short body.

“Now, what to pick…” she mumbled.

You steeled yourself, while not strong enough to break an outright order, your sister had not said anything about not speaking.

“Uhm… sis? I think-”

“Shut up.” she said, offhandedly as she browsed.

Well shit.

Caris’ eyes lit up for a moment. The excited shake in her wrist as she pressed down on the screen made your heart stutter even though you could not see what she was currently pressing on. She licked her lips, eyes agleam as she slid her finger across.

Throughout this experience you didn’t understand why whenever she made an adjustment to your pictures she never actually looked at the picture but instead watched you, as if something of significance was happening to you outside of it.

Then it hit you, the instructions when you’d first opened the app. Could it actually be something magical, something that could actually change you physically?

You tried to think, to remember anything changing but nothing seemed out of the ordinary as you looked at yourself.

Then you remembered the one line that could explain it… the “oblivious” option…

You took note of your sister’s crazed look of arousal and the clear sign of something wet at her crotch as she scrolled through the options again and the realization that you’d maxed out her perversion with “oblivious” turned on.

Fuck.

Looking down one last time, you tried to see if anything had changed, hoping beyond hope that if things were really changing then your sister had been merciful. But staring down you only saw your very normal fake double d’s, perfectly common hormonally grown ass and the familiar small bulge in the front of your tight shorts.

You looked back up, looking for any sign of mercy in your twin.

You felt like a piece of meat the way that your twin sister now watched you. Eyes roaming up and down your small and feminine form, you shifted slightly, pulling at the hem of your body-molding t-shirt.

You gulped, dreading what that look could possibly mean.
