The roar of the engine echoes his racing heart as he takes his place on the bike, naked and ready. The seat, warm from the sun, welcomes his throbbing cock. He leans forward, gripping the handlebars tightly as he starts to rock, the rhythm of the motorcycle mimicking the motion of a lover. His ass cheeks clench, his balls tighten, and with a guttural moan, he spurts his load onto the seat, the bike still purring beneath him.
