The city bus lurches forward, its engine rumbling like a beast in heat. In the back, a horny gay stud and his partner find themselves in a world of their own, the rest of the passengers mere blurs outside their window. The stud's cock is a thick, pulsing rod of flesh, and his partner hungrily takes it into his mouth, gagging on its length. The stud's hands grip his partner's head, fucking his face with wild abandon, his balls slapping against the other man's chin. The bus's motion only intensifies their pleasure, the stud's cock sliding in and out of his partner's mouth with increasing speed and force.
