Had a BBBJCIM recently where, when I started to cum in her mouth, she got very still; she let me do all the moving, thrusting, etc. she let me take her head in my hands and pump away. It was different and very hot and satisfying. And she was vocal, moaning while I was cumming. Vocals are ACCEPTED while we're exploding...
For you ladies that don't CIM, when I start to cum don't take your hands and rub across the most sensitive area, the head. Grab my penis at the base and squeeze lightly, moving up and down the shaft and STOPPING a little above the base of the head. When this is done right I can explode for 15-20 seconds.
