Soo me and my cousin(f) are close. We used to swap phone and go through each dirty messages and swap back. One day she didnt swap back right away. What I found was she was pretending to be me and was sexting her best friend(who was really hot). We ended up going to movie with her best friend. I sat in the back of the car on the way home before I knew it her bf jumps in the back and starts blowing me asking if this is how I imaged it. My cousin had a grin was rubbing her pussy till we got home.
