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

What he cared about most about this guy's sister was that the boy would wake up to take her to class in the car, but when he is 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 some licks to try on. He refuses, but it causes the fox to become even more desperate to try his cock inside the vagina, which he ends up getting because he is a slut and because he knows that even his brother would not resist having sex with her. The slut spreads her legs wide and finally says to put her on all fours to blow her off.
