Blackmails her sister for not betraying her and gets fucked

Sometimes when you blackmail someone you start betting little and you raise the bet as you see that you can do it, to try to get more slice. This guy has his sister well taken by the balls because he threatens to tell his father what he has done last night. At first he asks her to stay in her underwear and clean the house, but then blackmails her again by pressing her much more and she gets fucked. The slut is not funny that his brother puts his finger and cock, but the fuck is so intense that he cums like a good whore.
