Father punishes his masturbating daughter

In this teen's family they have a problem: their parents have discovered that the girl is a masturbating daughter. Or what is the same, a little fox that can't stop beating her fingers and getting vibrators through her pussy. Her parents want her to stop, but they don't know how to force her. They agree that her father fucks her several times to see if she learns, but it seems that makes her even more horny and has more desire to masturbate. So in the end the man has to fuck repeatedly to see if he changes his habits.
