I think it's very strange that everyone has decided that the girl is a slut. Clearly this is a male-domination fantasy of taking this sweet innocent girl (still associated with her mommy and daddy indicating her innocence and youth) who has never seen porn before and is bursting with sweet emotion, and turning her into his personal porn slut who he can then dismiss, probably with a smack and degradation. Like Faroukh said, Frank's just feeling horny and taking it out on her, hopefully just inside his head while he beats off at home alone.
