Bored and restless, brother and sister retreat to their rooms, masturbating to pass the time. She fingers her wet pussy, he strokes his hard cock. Caught in the act, they argue heatedly, but soon their anger turns to lust. Naked, they face each other, her eyes locked on his thick, straight cock. She fantasizes about it inside her, and he can't resist her tight, naked body. Just as they're about to fuck, someone enters, forcing them to halt their taboo encounter.
