Cristina, the busty alumnus, boards the bus, her tight dress drawing the driver's gaze. She notices his erection and, with a mischievous smile, sits beside him. Whispering her demands, she guides his hand under her dress, making him touch her wet pussy. She then takes out his cock, stroking it expertly until he cums, staining his uniform. The driver, now under her spell, stops the bus at her command, ready to satisfy her every whim.
