My step brother decided to come into my room to ask where our parents have gone to. I inform him that our parents will be gone for a bit and that he is welcome to hang for a little while. Things get...weird. I decided to go with the flow and I ended up sucking his cock. Then he blackmails me and tells me that if I don't fuck him, he will tell mom that I sucked his dick... I'm not even on birth control so I wanted to at least use a condom but he didnt' have any. I'm hoping I don't end up pregnant!!!
