Naive and innocent-looking, the teenage step-siblings find themselves alone in the house, their hormones raging. She's curious, he's eager. They start with a tentatively innocent make-out session on the couch, but her inexperience and his eagerness lead them down a path of no return. She tentatively takes his massive cock into her small mouth, gagging as she tries to deepthroat. He guides her, teaching her the art of giving head. Their bodies entwined, they explore each other's forbidden territories, their moans filling the empty house.
