Step sister doesn't want to share my cock

I found out that my hot stepbrother fucked my ex best friend. She is disgusting. She is telling everyone how big is cock is. I hate that she found out that he had a big dick first. It's so not fair. I'm way hotter than her and I know for a fact I suck better dick than her. I guess I'm going to just have to lay my claim and let my stepbrother know his cock is mine. And that is exactly what I did. I confronted him about fucking that nasty slut and told him his cock belongs to me. She wasn't lying his cock is so big and perfect. I love the way it fits deep in my throat when I gag on it. He was so hard! It was so fun jerking him off and telling him how mad I was that he fucked her. How it just made me want to suck his cock more. I put his thick shaft between my big tits and jerked him off. I showed him my beautiful ass and then sucked his dick some more. Then put him in between my titties again fucking him with them until he came. I cleaned him up with my mouth like a good loving sister. He better remember that cock belongs to me.
