Amanda's eyes suddenly lit up with excitement.
"Wait I want to try something on you Joey! It could be fun just go along with it, this is a magic dildo after all. You'll have to get undressed yourself first though."
I wished my clothes off and they automatically fell through my body to the floor. Amanda took the dildo from me and looked it over slowly. A smile appeared as she examined my nude body.
"Go on all 4's for me, it should make it easier. Just promise me you won't object until its finished."
"Sure I promise as long as I get to have some fun with you later."
"Thats no problem especially if I'm right."
I got down on all 4s with my rear facing Amanda. Suddenly a jolt of pain filled me as I let out a small grunt. She had shoved the dildo in my own anus, and I might have considered ending the whole experiment if it hadn't suddenly dissipated. My entire pelvic region shifted as it was being sucked into one point in between my legs. I looked back to see my penis sink into my skin and my balls retract back into my body. My anus and dildo moved together to where a vagina would normally have been placed and the waves of pleasure sweeping over me caused a squeak of pleasure. Rolling on my back I noticed how girlish it sounded but was soon distracted as my entire body shrunk to a size smaller than Amanda's own body. The hair was gone from the usual male places and I saw my own muscles take on a female character. As soon as everything seemed to stabilize I looked back up at Amanda mostly shocked but very excited at what she had just seen.
Silently I moved my hands over my new body and noticed it wasn't quite mature even. The age was obviously that of Amanda's but I had no breasts or even pubic hair. I felt down where my new vagina was, but I didn't see any sign of any other holes in the normal spots. My butt was absolutely smooth and without a split and my urethra had completely gone into me. The dildo had fallen back to the floor but it had filled its use for now.
"Even your face is female joey, I kind of expected a bit less but you do look sexy in an unusual way. Do you like it?"
She shifted in her place suggestively...
"I feel really turned on actually, is that really my voice? I sound even more girlish than you!"
"So Joey....or should I say Joanna"
She smiled again shyly.
"What do you want to do now?"
