Sister is staying with brother and his wife while going to college. They agreed she can stay as long as she gets a job and pays rent. She can't find a job because college has been alot so she talks to her brother about an arrangement. She talks about how shes always had a crush on him and is jealous of his wife and would love to give him head and fuck everyday instead of paying rent. She will do whatever for him and he agrees that the idea is good. He fucks her so good but she makes him cum deep inside her even though she isnt on birth control. He knows his sister feels so much better than his wife.
