One by one, the other bad boys start to undo their pants, their cocks springing free. They stroke themselves in time with the bouncing of the car, the sound of skin on skin making your stomach twist. You're aware of the audience watching, the thought of all those eyes on you making your humiliation complete. Marcus's grunts become louder, and you feel his cock swell in your mouth. You know he's close, and you brace yourself for the inevitable. "Swallow it, slut," he says, his voice strained. He pulls out and shoots his load across your face, the sticky warmth of his cum hitting your glasses and making you blink rapidly. The other boys laugh, their eyes gleaming as they watch.
