Taking Over Your Sister's Body

I did it. I took over her body.. but, not just anyone's body- my bully's sister's body. It feels amazing to be in her body and caressing her tits as if they were my own. Oh and here is her brother coming into her room now. He wants to know why I've been so flirty towards him. Little does he know of my plan to have his own sister seduce him so I can blackmail him.. I want to catch him being a sister fucker and I want to stay in this bitch's body forever. However, a cream pie is the only way to insure I stay in this body. I'll need to make sure to get on top of him so I can take the lead with the fucking and get him to accidently bust inside me. At the climax of the moment that's when I'll tell him... That's when I'll tell him I took over his sister's body.
