To pull over and masturbate when driving long distances. Much like the advised "power nap" to avoid accidents.

To 'beat the meat' within seconds of ejaculation, then stopping. Enjoy the feeling for a while. Wait for the feeling to stop, then beat until you are within seconds of blowing again. Repeat for a good few hours, then while you do finally blow your load, it will feel a million times better than any wank, blowjob, fuck or sheep shagging.

Well recommended.

Man 1: Hello?

Man 2: Alright dude?

Man 1: Fuck off, I'm having a wank.

Man 2: Fair play, I'll call you back in 5 then?

Man 1: No. I'm having a power wank...

Man 2: A who wank?

Man 1: *sigh* Just call me back in 3 hours.

Man 2: 3 HOURS?!

In the case of extreme horniness and unable to find the proper equipment (magazines,internet,movies etc)and you are in a public place (school,work etc). A power-wank is the answer. Max time 30 seconds. You go into that loo and bash at your member so hard your hand almost falls off.

Can be used in competition: who can wank the quickest. Wud only advise if reali drunk or you dont mind group masturbation
"Joe you were quick in the loo?"
"oh thx just went for a power-wank to clean the pipes"
