This uncle's sister is desperate because she puts his cock

What he worried most about this guy's sister was that the kid would wake up to take her to class in the car, but when he is being left to get out of bed he sees that he has a very hard cock. And he tells her that he would like to give her a couple of licks to try it. He refuses, but that leads to the fox being even more desperate to try his cock inside the pussy, which he ends up getting because he is a slut and because he knows that not even his brother would resist fucking her. The slut spreads her legs wide and finally tells her to put her on all fours to bust her.
