I really enjoy how well most of my patients respond to the Sybian. My goal is always to see if they can cum hands free but it's hard for me to sit there without helping.
I want them to thoroughly enjoy each session so they keep coming back every week so I know the best way to do this is get my hands in there and milk them dry.
I've been practicing my edging technique by stroking the cock a little, then playing with the balls and going back and fourth. This has been working very well at producing bigger loads.
