This seems pretty silly to you. You decide to try a totally out-there wish so it can't be a coincidence if it works. "Make me into a girl!" you say as you point the wand at yourself. You laugh, put it back down and lie on your bed again. Seems like that thing was just a prank...
Then you feel the tenseness in your chest. It feels like something is pushing up from under the skin, your chest aching as you breathe. What the hell is that? Suddenly you pant as your nipples suddenly become ten times more sensitive and rub tenderly against your T shirt. It feels good. You pull off your shirt confusedly, and notice that your chest suddenly looks bigger and rounder, and your nipples have turned more pronounced. When you get up and look at yourself in the mirror, you notice your face has feminized. It's obviously still you, but like, you if you were a girl. Your chest is still growing, your nipples turning more pleasurable. That's impossible, you think to yourself... and then a gurgling sound accompanies your figure reshaping subtly, and you feel a tension in your thighs and butt.
Removing your jeans and underwear, you grunt as your hips widen and your butt rounds into a softer, more feminine shape. Your hands and feet have shrunken slightly as well, and your body is a little less muscular. You now realize the last part of your body left to change, and your antipathy about losing it gives way to desire when the head pulses with nerve endings accumulating around it, the balls moving up inside you and the scrotum starting to tuck in and sculpt itself into lips. You feel a burning urge to take something inside you suddenly emerge in your mind, watching eagerly as your penis shrinks and reshapes into your clitoris, and moaning as your new slit opens, a subtle passage inside you replacing your cock and balls. There's no doubt about it, that wand works.
