Bored siblings David and Maria find themselves alone, their parents out for the night. David's eyes wander to Maria's curves, her innocent face hidden behind a book. She catches him, anger flaring, 'Don't look at me like that, David!' But her words betray her, her voice quivering with unexpected desire. They argue, tension building, until Maria impulsively kisses him. David's hands roam her body, feeling her breath hitch as he cups her breast. 'We can't,' she gasps, but her body says otherwise.
