I suck my brother\'s dick in exchange for money

This girl wants to go on a trip with her friends, but her parents don't want to give her any money. She has behaved very badly throughout the school year and has failed all her subjects. She has an older brother who works and the girl goes to him for a loan so she can travel with her friends. The boy is quite perverted and takes advantage of the situation, and tells his sister that she can give him all the money for the trip, but if she makes him a dick sucking lips and facials. The girl feels offended and threatens to tell her parents, but since she knows they won't believe her and that her brother is the only solution, she decides to accept the offer and starts sucking his dick in a very perverse and professional way.
