His little sister encourages him to fuck him after suffering an injury

The boy has suffered an injury and is very sad because he cannot compete in the next sports games of his school. So his little sister, in view of the situation, intends to encourage him. He asks him to sit on the couch and relax, and what he does next is slowly approach his cock to suck it. Then they go to the room and there the sister does all the hard work moving her hips and her piece of ass while they throw a powder with which the uncle is super relaxed and very encouraged to know that he can always fuck his sister.
