A two-handed hand-job that is performed using large quantities of lube (I.E. KY or saliva), and definitely both hands. To do the double dragon, the giver must be using the left and right hands to twist and slide up and down the shaft, while the receiver makes thrusting motions, and the hands must be locked together and work as a double dragon sliding up and down the cock, while rotating around and sliding up and down vigorously. Often results in massive splooge.
Me and Marie went to 7/11 where I bought some lube and she gave me the ultimate 'Double Dragon' around back.
