I fuck my sister-in-law for her tits

Since he met his girlfriend's younger sister, this man lost his head and became aroused. She's too sexy, with big tits and always wearing the best necklines in town. She's also quite outgoing, so she's always making conversation with her brother-in-law and telling him funny stories about her and her friends in high school. One afternoon the boy decides to go visit his girlfriend as a surprise, but he doesn't get it, only his sister-in-law is there and he stays to talk to her. The girl takes a very sensual attitude and starts asking the brother-in-law how his sex life is with his sister. The man picks up the signals and after a few minutes he has her on his back and decides to take advantage of her tits to fuck her.
