With a hunger in her eyes, she stares at the massive cock in her hand, her heart pounding with anticipation. She's alone, vulnerable, but her desire is insatiable. She strokes her thick, throbbing shaft, her fingers barely able to wrap around its girth. She imagines the sensation of it filling her, stretching her, as she continues to pump her fist, her breath coming in short gasps. She can feel her orgasm building, her body tensing, as she races towards the edge. Just as she's about to tumble over, a sudden noise outside her door brings her back to reality, her heart pounding with a mix of fear and arousal.
