Too shocked to do anything

You cannot stop looking at yourself in the mirror. You kinda look like a younger version of your sister with more defined feminine traits. Speaking of which, you were plump in all those awkward places. Your butt, your chest, all of it so soft, so pleasurable to grab. You would probably be attracted to this girl if you were on highschool. Would guys...

"You done staring at yourself?" Zoe interrupts your thoughts. You slowly nod your head in fear. You think of doing terrible things to her, but the sight of the gun in her hands discourages you from acting on them. "Did you like it?"

"P-please Zoe, turn me back, I'll do anything..." It takes every fiber of your willpower to ignore how 'girly' your voice sounds.

"Hmmmm..." Your big-titted sister thinks while playing with the ray gun in her hands.
