Cowboys Cheerleader step-Sister

You sneak into your step-sister room and realize she is wearing a Dallas Cowboys cheerleader costume. You know she's been a cheerleader your whole life and thought she was joking because you guys aren't that close to know details about each other's lives. But she really recently just became one! You are turned on by her and ask her to dance for you! She is shy but shows you! As she fixes her top, she accidentally shows you her tits. You compliment her because you are turned on by her... which leads to her showing you her full bare tits, pulling down her shorts, and having sex with you! *pov sex with dildo but with implied cumming
