Mack, her baby bump visible under her tight shirt, steps onto the bus, her eyes scanning for opportunity. Spotting a well-endowed passenger, she propositions him, her voice barely audible over the engine's hum. She drops to her knees, her short hair brushing against his thighs as she unzips him. Mack's inexperience shows, but her enthusiasm makes up for it. She licks and sucks, her cheeks hollowing, her eyes locked onto the camera, her pregnant body swaying with the bus's movements. The passengers watch, some horrified, others aroused, as Mack's reality turns into a public, paid blowjob spectacle.
