Ever since he was little he has been very jealous of his brother, because he always got better grades and was given the best gifts. Currently his brother has a girlfriend who is quite sexy, and this man decides to seduce her to cheat on his brother and make him suffer. One afternoon he invites her to the house and when they are alone in a room he tells her that he wants to fuck her without her brother finding out, the girl gets flirtatious and agrees to be unfaithful with her brother-in-law.
