I have to keep still when the mistress wants to touch my cock. For I am her sex object. She presses my glans together with both hands. I feel dizzy with lust. And always nicely up and down the shaft. The urethra has to be squeezed tightly towards the glans to squeeze all the pre-ejaculate out of the cock. Just grip it firmly. That's how it should be. You drive me crazy and as demanded I give you what you want from me.
