It's Halloween. Your mates are going out clubbing without you, so to get in the Halloween spirit you decide to mess around with a Ouija board. It starts moving by itself, freaked the fuck out you put it somewhere safe and go to bed.
You open your eyes the following morning, what are you doing in your StepMom's bed!? Something feels weird. Why have you got hair and... tits!? WTF, surely this is just a dream!? You go into your bedroom and find yourself in there, shaking yourself the two of you realise you and your StepMom have swapped bodies! This can't be happening, you have to find a way to swap back! Aint no way you're going to work... or worse... fucking your StepDad GROSS. Your two bodies need to collide somehow... is it weird that you're enjoying the feeling of fucking your own cock, fucking your StepMom!? After multiple failed attempts of swapping back, you've both had enough! You don't want to be a Woman!! You run into each other in a final attempt to exchange bodies, but unfortunately StepMom is out. No one can ever find out about this, you have a reputation as a "lad" to uphold. You lock your old body in a cupboard, look around a smile as you begin to explore your sexy new body in private.
Fuck maybe being a Woman aint so bad after all, you're addicted to strumming one out and playing with your StepMom's wet cunt. It feels so much better for a Woman, bean flicking is your new favorite hobby. But you can't stop thinking about how good StepMom's cock felt in there, you're gagging for a cock. Any cock will do at this point.
You decide to rip the plaster off and get all dressed up to seduce StepDaddy. He'll be that dickmatized by his sexy new Wife he won't even realise she's acting a little bit different. He even loves it when you call him StepDaddy, throwing a taboo roleplay into your wild sexual encounter you've turned into a slag for taboo sex.
But unfortunately StepDaddy and his taboo cock won't be around for the rest of the week because of his stupid business trip. Addicted to taboo sex, there's one final stepFamily member you haven't had the pleasure of fucking yet...
