Edging with vibrator

I edge with a vibrator and after doing it for a lil bit I feel my whole cock fill up with cum and then after that the cum will shake and vibrate in my cock with some cumming out dripping down as I go and I keep building up more and more so im overflowing basically and that cum shaking makes me orgasim, there is a spot in the cock that when cum touches it and moves on it that causes orgasim i figured out how to keep the cum on that spot and just cum the whole time and the longer I go the more Intense it gets, using a vibrator of some kind makes it possible for me, I just gotta be carful to every few min take it off for 30 sec or so just so I dont start to fully unload everything till im ready to anyway.
