When a girl is riding on the back of a motorcycle with a guy driving and suddenly she's in a big hurry to get somewhere. So, she reaches around, pulls his penis out and starts stroking it. Although not official, generally the guy will accelerate the motorcycle pro rata with the rate of speed of the hand job.

The passengers on the Amish tour bus were puzzled when a dutch hand job passed them on a moped.
