Zoe shifted upright on her knees, tenderly stroking her thighs.
"I've always wanted to have sex with myself. Looking in the mirror and seeing the things that I can do to my body has always been such a turn on. And while I have a body that do this..."
Jon watched as Zoe morphed clit into a penis which stretched and slithered over her legs and into her asshole. She started moaning as she pulled it out like a hose, retracting it into her vagina. She then fisted into her vagina stretching her arm through her ass, causing her to moan very deeply and giving Jon another erection.
Her orgasm Zoey continued, with her hand sticking out of her asshole
"That feels so good. But I want to be able to fuck myself like you fucked me. And thats where I need your help Jon" she said
She yanked her hand out of her pussy, leaving an enormous hole where her vagina was eliciting another shout of pleasure as she closed it up.
Inspite of his hard on, Jon wasn't entirely sure about what she was saying
"Hold on, the sex was great and all. But you're my sister, this is all starting to get really weird for me"
Zoe smiled at him "So what if I'm your sister? I'm barely human, I can transform into whatever I want. Would you prefer it if I look like this?" Her form shifted, her putty body morphing into a young asian woman with blond hair "or how about your girlfriend?", morphing into a naked duplicate of Karyn
"Zoe, she's not my girlfriend"
"Oh come on" Zoe replied in her voice "I've seen the way you look at me, you're just dying to sex with me" she said, enlargening her breasts.
"Zoe you're making this weird for me"
"Fine how about this" as she morphed into (insert female actress) "I know you always had a boner for her" she said, imitating her voice.
"Alright, fine" Jon submitted "So what do you want me to do?"
"I dunno" Zoe said, rotating her head 180 degrees facing the reader "what do you want me to do next?"
