My Step Brother Agreed To A Threesome

They were talking about stupid stuff. AGAIN. I tried to get their attention but they ignored me. I decided to drop something on the floor and pick it up, showing off my big ass. My brother got embarrassed by my behavior and went off about how I am just a hoe. I hopped on his friends lap and grinded on him. I got all hot and bothered and seeing my brothers boner put me over the edge. I think skipping the condom for my brother would be the hottest thing.
