Very vicious little sister strips in front of him to fuck her

The father of this uncle's very vicious sister is worried about her and asks her son to take care of everything he can about her so that no boy bothers her. But the sister is a bit of a whore and as she knows that her father is tying her short, what she does is undress in front of her brother to see if she gets horny and fucks her. With those pieces of tits it is obvious what will end up happening, so the brother approaches her and in a few minutes he is already fucking her. But in the end the father catches them!
