I have been able to have my wife, fwb and fb squirt regularly in addition to a few others from time to time. They not only need to be totally relaxed in my opinion and comfortable with who they are with but also in a totally hot mood where they can let themselves go and enjoy the moment. It is a combination of oral and digital stimulation for a bit of unrushed time and the affect earthshaking. I have had partners who actually refer me to friends for purely sexual pleasure.
