Gia has a new boyfriend named Rob that stepdad does not approve of. He would go to any length to make sure he protects his stepdaughter from this heartbreaker. So he's pretty upset when he comes home to hear his innocent stepdaughter giggling and making sounds he does not want coming out of her mouth, all behind a closed door. Gia is not following his house rules of keeping the door open three inches. Just shy of beating the bedroom door down, he opens it to find them casually sitting on her bed. It's almost as if they are mocking him. He leaves only to hear muffled moans and wet mouths once more. He's had the last straw and kicks Rob out. Gia and Rob decide they are adults and fuck this old man's rules, they can do whatever they want. So they bait him into insanity. Poor old stepdad finds himself locked out of his precious stepdaughter's room, while she fucks into oblivion...
