Religious Guilt's Forbidden Fruition

A young woman and her stepsibling find themselves alone, bored, and horny. She fingers her wet pussy while he strokes his thick, straight cock, both trying to be quiet. Caught in the act, they argue, but later, they decide to masturbate openly in front of each other. The sight of his massive dick excites her, and she fantasizes about feeling it inside her. Just as they're about to act on their mutual desire, someone enters, forcing them to abruptly end their erotic encounter.
