The siblings' eyes meet, gleaming with illicit intent. The girl, her heart pounding, sinks down onto her brother's throbbing cock. She's never been with anyone, but her body knows what it wants. She begins to move, slowly at first, then faster, as her brother's hands grip her hips. Their moans grow louder, more urgent, as they lose themselves in the forbidden act. They're haunted by guilt, but their bodies betray them, hungry for more. The closet fills with the scent of their arousal, a heady perfume of sin and desire.
