Incest Daughter and Divorced Father (F for M)

[Usani]

It's not much of a plot but I was thinking of something where my character sees her dad masturbating and watches him in secret.  But, she doesn't realize her dad knows shes been watching him.  He doesn't let on for a while that he knows but its isnt until he walks into her room and catches her masturbating to lesbian porn. What happens then??
