Use it on yourself, and think of a smart (but naughty) school girl

You think that it would be cool to try being a girl, but you have enough personal insight to tell you that your stereotype of a girl... might not be what you personally would like to be. You close your eyes, take a few long breaths to clear your mind and focus.

A disciplined woman with talent and drive. yes, that's good, you nod to yourself, opening one eye to look at the gun as you raise it up and feel the heft of it.

Popular with brains and looks. A very good addition, you concede, and aim the gun towards your chest, feeling the trigger with your finger.

-That sometimes lets her shameless and horny body get the better part of her-. Some stubborn and horny part of your brain quickly add just as you squeeze the trigger. Your eyes flash open as the gun makes a charging sound, but before you can turn it away, a white flash envelops you.

You blink and finds yourself sitting in the dorm sofa with the slightly smoking stereotype gun in your hands. You curse to yourself as you jump out of the couch and check out your body. You weren't wearing much, a loose crop top that would flash a pert nipple at the right angle, a pair of tight hipster panties, hair tied in a bun and a pair of comfortable but not very fashionable reading glasses on your nose. What you'd normally wear at home after a long day with an exam to study for. However, something felt... new, yet old. You fired the stereotype gun at yourself, and you used to be some... boy named Mark, and not a girl named Marcy? It felt like a weird dream, those felt way too real, but reality didn't seem to assert itself like it usually does when you awaken.

You skip over to your room, finding it just the same, but also completely different. You open your night stand drawer to find... an assortment of lube and sex toys, and not dirty magazines. You kind of wants to put some of those toys to use, but you feel that you should worry more about the stereotype gun...
