"Kaytano spends the afternoon tidying up the apartment to receive his sister and brother-in-law, Titto - the man who has always aroused in him a curious mixture of admiration and repressed desire. When he receives a message that his sister will be late, Kaytano finds himself alone with his brother-in-law for the first time. As soon as he arrives at the apartment that Kaytano shares with his sister, Titto, relaxed, decides to take a shower, and Kaytano, overcome by curiosity, cannot resist trying to find out if the rumours 'bout his brother-in-law's package was real. The moment of indiscretion turns into a dangerous game when Titto notices the invasive gaze. At first, Titto is uncomfortable with the situation, but the tension between the two, until then hidden under the veil of family, finally manifests itself in an intense and forbidden exchange of energy. Caught between fear and desire, Kaytano and Titto cross the line that separates the right from the irresistible. What begins as an embarrassing encounter transforms into an experience that neither of them will be able to forget. "My Brother-In-Law's Package" is a film about repressed desires, the temptation of the forbidden, and the thrill of adrenaline. Titto transforms Kaytano's hole into a pussy while his sister, the cuckquean , has no idea that her room has become a motel for her husband and her own brother."
