requires two men both holding their cocks. Each man grabs their fellows fore arm and controls the motion of their partner's hand on their penis.

Like a dutch rudder, but in addition to holding your own penis with the perfect grip while another person moves your arm up and down for a relaxing effort free handjob exactly how you like it. A double dutch rudder is when you do the above but also shave one of your legs and have a 3rd person move your shaved leg over your hairy leg gently to give the sensation of a women's leg while you rub one out.

all in all just a dutch rudder but with two males each holding there own penis and performing the act on each other with there other arm.

Like a Dutch Rudder except this act is completely with Another Man. You both grab each others forearm and shake it thus helping the other person masturbate. Does not work will if the 2 individuals are not both right handed or both left handed.

Interlock your manhood with both hands and have two lady friends on either sides working your arms for you. It very much helps if they stay in synch.
