Janet Jacme's pulse quickens as the metro car fills up, a suited stranger standing close, his breath warm on her neck. She leans back, her ass rubbing against his crotch, feeling his growing bulge. His hands grip the railings, knuckles turning white, as Janet grinds subtly, a wicked smile playing on her lips. She can feel his heart racing, matching her own. The train lurches, pressing them together, Janet's hand reaching down to stroke her wet slit through her panties, inviting the stranger to join her in this illicit, public display of lust.
