My sister's used panties, carelessly left on her bedroom floor, call out to me like a siren's song. I can't help but pick them up, feeling the warmth and dampness that betray her recent arousal. My heart races as I press the silky fabric to my face, my own body responding to the intimate scent. I begin to stroke myself, lost in the fantasy of her hands on my body, until I hear her voice, snapping me back to reality and reminding me of the dangerous game I'm playing.
