Plump bottomed beauty boards the bus, her ample assets drawing envious glances. She settles into a seat, her skirt riding up to reveal tantalizing glimpses of her thigh-high stockings. As the bus lurches forward, she begins to squirm, her hand discreetly slipping between her legs. Her eyes flutter closed, lost in her own world, as she rubs herself through her panties, her breath hitching as she nears her climax. Unbeknownst to her, a fellow passenger watches, his own hand moving in rhythm with hers.
