One of my favorite ways to edge a sub is:
Fucking them until their legs start to shake and their voice is starting to tremble….then stopping. Waiting. Waiting until I can see it in their eyes that they have gathered themselves and are no longer heading into the blissful orgasm abyss…
Then starting again. This time with calculated, hard thrusts. A slow, teasing pace to start before I bring them back to the edge of glory, again and again, with no release.
Until I finally let them cum after what seems like hours. 😈
