The bus lurches forward, the teen's heart pounding in sync. Her destination isn't a place, but the taboo thrill she craves. She spots a willing participant, her eyes locked with his as she saunters down the aisle. Her hand trails along the seat backs, fingers brushing against his thigh. He responds, his hand covering hers, guiding it to his growing bulge. She smiles, leaning in, her lips brushing against his ear. "How much?" she whispers. He shows her the bills, and she nods, leading him to the back, where the shadows hide their transaction. The bus bounces over potholes, her body grinding against his, his hands exploring her curves. The ride is short, but the memory of her tight, wet pussy around his cock will last long after the bus pulls away.
