Emily's step-dad, a sadist with a soft spot for his step-daughter, has her bound and at his mercy. He attaches piercing clamps to her tender nipples, watching her squirm in pleasure-pain. With a buzzing vibrator, he explores her pussy, making her beg for more. He edges her, bringing her to the brink of orgasm only to back off, leaving her desperate. Finally, he lets her cum, and cum she does, squirting repeatedly, her body convulsing with each climax.
