Originally commissioned as a custom - no named are used. You have always been curious how it feels to be a Woman, how good it must feel to masturbate as a Woman. You begin to feel jealous of anybody that crosses your path with a vagina, upset that you will never get to experience this. It begins to take over your life, you know your Friends and StepParents would judge you for having these thoughts - after all it isn't normal to want to be a Woman. The only person you can talk to is your StepAunt, she is different to your StepMom and is very caring and understanding. She is worried about you, and hates seeing you this upset. She will do anything to help you live out your ultimate fantasy... And that's when she tells you about her book of spells, and how one spell that she cast on her ex actually came true! Unfortunately she can't just turn you into a Woman... however there is a body swap spell. She would be more than happy to do it with you, she would love to be young again and has also fantasized about what it feels like for a Man to cum. You open your eyes and look down to see your new form - beautiful perky tits... and your wish came true - you finally have a vagina to play with! It's wet already at the thought of touching it. You look over at your old body, your StepAunt is already playing with your cock and she is shocked at how big you are. You can't wait any longer - this is YOUR body and is all yours to explore. Fuck it feels just as magical as you expected, you want to stay in your StepAunt's body forever! You encourage your StepAunt to stroke her new cock, and you tell her exactly what feels good. You watch each other masturbate realizing how fucked up this is, but nobody will ever know. You wink at each other and your StepAunt gets between your legs and licks your pussy bringing you to orgasm - it feels so much better for a Woman! It would be rude not to return the favour, after all you could do with some practice seeing as you will be remaining in her body forever. You look up at your old self as you suck your own cock, your StepAunt shoots her load down your throat and you swallow every last drop of that forbidden seed.
