Ask the girl for help changing

?Excuse me miss, I need help changing into a girl.?

“Really, just like that. But how did you even know I was a witch?”

You have no idea what she is talking about but you decide to play along, “Why look at you. I could feel the magic energy ebbing from you from across the store.” Heh heh, love those theater classes you took over the summer. “Please miss, can you take me to the room where you perform your awesome craft and help me change. You know the changing room.”

“Oh I see you are a smart ass. Get lost.”

“No wait, I am sorry I really want to change, where do I go. I don’t see a sign anywhere.”

“Ok, you want it you got it. Follow me.” She walks back through the store and into the storeroom. You follow her with a big grin on your face, not exactly sure if you somehow make her mad or if she is just playing along for Halloween. She leads you into a little room with a pentagram drawn on the floor with a golden goblet sitting in the middle of the inner circle as well as a long thin knife. “Strip, go into the circle, cut your finger, drip the blood into the goblet. Say the words, Mother earth, by all the powers of all hallows eve remake me into the form of the blessed fairer sex till the end of the night of the dead.” She points at the circle, “While you are doing this I will chant and summon the creatures capable of performing such a feat, a sex demon.”
