Beta for your BF's Step-Sister

You are such a simp for your best friend’s step-sister, the way you get lost looking at her, and forget to talk when you’re around her, it’s not a secret. Today, I sees perfect opportunity to use your attraction to my advantage, to turn you from simp to slave. You will go from just pining over me and doing random things for me when you’re hanging out with my step-brother to living to serve me, to worshiping my feet and becoming my little slave forever. You will literally DO ANYTHING for me, so let’s make it real, forget about chasing pussy, you will never be able to get a woman like me, so you may as well cut off the chase, and settle into your submissive position at my feet, it’s the greatest honor your beta life could ever wish for!
