One of my absolute favorite fetishes is edging, purely because how it effects your mind.
You start to realize that the orgasm may be the best part yes... but it only lasts what a few seconds? And then you are desperate craving more...
But the edging it can go on for hours, days weeks, even months...
Everyday the build up would become a little more intense and yes you may not get to cum but you will become overwhelmed with the need to keep on edging
