this ability requires some good lungs. it is also an ability that Twilar would be very good at, or should i say is already very good at(he just doesnt know how to aply his ki to this ordinary task). too bad hes gone though.
you must do breathing exercizes first, this is to build up your lungs better(not required but you will get better returns from the person you wish to drain from with a better lung capacity) now, aproach the person, you dont have to know them, but make sure they wont mind or you might get punched (damned them guys at the bar, i just wanted to have some fun) Ive done this to Immoral many times, but never took any power from him since i just recently learned how to apply my Ki to it. You must get on your knees, carefully unzipping their pants(this is also not nessasary), you must pull out their Penis, it may be limp but that will change dureing the next part. Open your mouth like your going to eat something, then just slide your mouth over the cock. Now it should be hard. move your head up and down, you can do this quickly or slowly, though, be sure to close your lips around it and suck, USE THEM LUNGS. now, after a while some liquid will come out, dont worry, you didnt do it wrong thats suppose to happen. trust me im an expert. Now when this begin you must begin to hum in your throat, aum aum aum. and concentrate on their ki, see it, feel. Now imagine it flowing from their penis and into your mouth. feel their energy in you mouth, now swollow.
Congradulations, you just did a power drain. Use you new found power carefully. ~ aeromaster
