She tells you to unzip your pants and you do so. She pulls down her gown and you see her perky tits.You have never been more thankful that a girl was dumped in your life. Britney tells you to stroke it and she seems impressed with the size of your dick. Britney confesses that she felt your boner when you were dancing with her earlier. You really never thought about doing anything sexual with Britney before, but now that she is 18 years old, you feel okay about what you are doing with her right now. She lifts up her gown and you see pink panties peeking out from underneath, but you really wish she would take the prom dress off and let you see all of her. She slides her panties to the side and you can now see that pretty pussy. It looks so very tight that you wonder if she is still a virgin.
