Step-Sister CONTROLLED! Entranced Stepsister Fucks You At Her Engagement Party!

I'm at my engagement party. You, my stepbrother, bring me to my bedroom to give me a gift. I gently ask you to hurry up - my fiance is waiting for me! It turns out, you wrote a poem for me. It's so sweet! I read it out loud, laughing at the silly rhymes. But then the poem gets weird. It mentions you regretting not kissing me, and how that's going to change right now. I'm creeped out and ask you to explain it to me. I must be misunderstanding right? Before you can respond, it happens. The poem lights up, blinding me. The paper vibrates uncontrollably, making my whole body shake and shiver. I'm getting entranced! My eyes roll back as I lose control of myself and the spell takes hold of me. When it's done ... I'm an obedient slut. Or at least my body is. You tell me to touch your cock and I can't stop my hand from reaching out to stroke it. I'm your stepsister, are you crazy?! What did you do to me?? I reluctantly suck your dick, trying to resist the urge to give in, to lose myself to the spell and become your obedient fucktoy stepsister. But that's exactly what happens. When you start fucking my tight taboo pussy, I call you a pervert and moan about how fucked up this is ... but I can't stop myself from enjoying it. I get on top and ride my stepbrother's cock with my fiance right outside! I even take off my engagement ring and throw it across the room! Now that I've felt my own stepbrother's cock deep in my pussy, I'll never be able to go back now. The spell worked - your stepsister is your fucktoy now!
