Her eyes locked onto his, she slowly licks her lips, tracing the outline of her mouth with her tongue. He watches, enraptured, as she reaches down, hiking up her skirt to reveal her soaked panties. She rubs herself, moaning softly, her eyes never leaving his. The air is thick with their shared lust, the scent of their arousal mingling as they inch closer to the point of no return.
