Blackmails her sister for not cheating on her and gets fucked

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