I had a girlfriend back in the 80's that would tie me up and edge me. I BEGGED for her to let me cum. But only when she decided. Then once I did explode, she would not stop the stimulation. I thought I was going to pass out. "Exquisite torture" we called it.
My lady friend has done this to me, many times and always makes me beg her to let me Explode and I always have to beg her to stop stroking me, after I have Exploded in her hands. What an awesome feeling! Paul
