Hidden away in their father's study, the siblings find themselves alone and tempted. The brother, his cock straining against his pants, can't help but stare at his sister's ample cleavage, her breasts heaving with each breath. She catches him looking and, instead of admonishing him, she leans in, her voice barely above a whisper, "You want to see more, don't you?" She pulls down her top, revealing her large, round breasts, her nipples hard and begging to be touched. He hesitates, his hand trembling as he reaches out, ready to succumb to the putain within.
