A lone boy, hidden, watches as a girl undresses, her body glistening with sweat. She's unaware, lost in her private dance, fingers exploring her slick folds. His breath hitches, his hand moving to his throbbing cock, stroking in rhythm with her movements. She pauses, sensing something, her eyes scanning the room, meeting his gaze briefly before she continues, now knowing she's being watched, her performance fueled by the unknown observer.
