Jacking it to Sierra's fat ass

Sierra has a fat ass and she wants to show it to you. She stands up and wiggles it in your face. Take your dick out of your pants and get ready to work it while Sierra plays with her ass just for you. She takes out some oil and spreads it on her ass cheeks. Her cheeks are shiny and perfect. The way they giggle makes you weak. With all that oil, you know that your dick would just glide between her cheeks. You can almost feel the warmth radiating from her body as she stands before you teasing you with her juicy butt. Sierra hops onto the couch and slides down her thong, again wiggling and jiggling her butt in your direction. You now see her tight asshole and her pussy. If she would just back up a few inches, she would be sitting on your face. She knows that her ass holds power over you and your dick. You would do anything for it, wouldn't you?
