"You mean, become the opposite gender? To become my gender? You mean that?" She asked.
"Y-Yes... Yes. I'm sure. I would like to try it out, if it's OK with you..." I replied. This was awkward.
"Oh, of course! No problem. Hold still." She waved her a hands a little, muttering something under her breath. Immediately my wavy, black hair flowed down to my shoulders, which had shrunk, along with the rest of my body, becoming more slender and smooth. I ran a long-fingered hand over my hairless arms, revelling in the feeling. I felt a small twitch and my nose shrunk, eyes changing from brown to hazel, and lips becoming fuller.
A small tingle in my chest, my now limp clothes beginning to bulge slightly. I took a look to find 2 average B-cup breasts fill my shirt, enticing my male mind with hypnotic bouncing. I reached for them with my hands, feeling their strange weight, their new shape. It all felt so wonderful. I realised I was getting aroused and my penis was slowly stretching up, forcing me to remember that Sheila was still in the room, almost silently muttering. I blushed, but more for the fact that my member was now becoming smaller, staying erect. A squirm and my boxers no longer bulged. I felt a small pop and felt my penis no more. A slither worked it's way around my groin, forming new genitalia from the old. My hips widened, bottom pushing out, legs growing slightly.
I brushed a wave of black hair from my eyes and took my hands from my body. Slowly, I turned my head to Sheila.
"Wow..." Was all I could say. "Thank you."
"For someone like you, you're welcome!" She replied, happy with her handiwork.
