A lone runner on the treadmill, lost in the rhythm of her pounding feet and the music pulsating through her headphones, is unaware of the predator lurking nearby. As she increases her pace, so does he, until he's right behind her, his breath hot on her neck. She can feel his eyes on her, tracing the curves of her body, the rise and fall of her breasts. When she dares to look back, she sees the hunger in his eyes, the promise of a primal, animalistic encounter that will leave them both breathless and spent.
