Daddy's Girls.

Bob and Dale are best friends. They're both married. Bob to Gina and Dale to Iris. They both have teenage daughters. Dale's teenage daughter, Samantha, is blind and just back in town from a three month stint at a mental hospital, having tried to commit suicide after Bob took her virginity and unceremoniously dumped her. Meanwhile, Bob's daughter, Quincy has problems of her own, hosting a webcam sex site where she performs nasty acts for older men so that she can vent her sexual frustration over the fact that her own father, Bob refuses to fuck her, much to her horny chagrin.
