He watches, enraptured, as she plays with her pussy, her fingers glistening. He can't help but stroke his cock, imagining her tight pussy wrapped around him. Their eyes meet, and for a moment, they consider crossing that final line, but the fear of discovery holds them back, leaving them panting and aching for more.
