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"

"go"

The act of wanking to ultimate pleasure. This is done by assembling 3 computer screens side by side, putting porn on all 3 of them and then blasting your stereo with dubstep so you can't hear anything else. Proceed.
