In her mother's absence, she is her father's prostitute.

For a daughter to become a prostitute to her father is unusual. In incestuous relationships like this, she has to be a very helpful daughter who wants to please her father in everything or a girl in love with him. In this case, the first requirement is met, because the girl lives in her parents' house and, as she does not wish to become independent, what she does is cover her mother when she travels. He picks up his father's straws, sucks his cock and lets him fuck her in bed while watching TV, as he does in this video they recorded.
