The bus rumbles along deserted streets, its headlights slicing through the night. Inside, two young men, barely legal, sit side by side, thighs touching, hands hidden in their laps. Their breathing syncs, growing heavier as they rub their cocks, hidden from the driver's rearview mirror. The bus's motion adds a rhythm to their strokes, their hips bucking slightly. The air fills with their quiet moans, the scent of their precum mingling. They cum together, their loads dripping onto the floor, a secret mess left behind as the bus rolls on, their bodies relaxing, hearts pounding with the thrill of their public masturbation.
