Training a girl to wait

My Master used a maddeningly effective training visualization exercise to train me to both stay sexually tuned but to wait on his command.

He brought me to a peak of arousal with his words and then he commanded me to open my legs for him. Parting my petals, he thrust what he described as a large but fragile glass dildo in my pussy. He then put my iron belt on to hold it in place.... and went off to do other stuff humming a little tune. I was to stay in place and describe the feelings, the contour of the dildo inside me. However I could not make the slightest contraction of my pussy or the glass could shatter inside me causing pain and damage.

I felt the smooth curved contour of my Master's toy holding me open, filling me, holding his place like a bookmark. The sensation of penetration made me want to contract desperately but I knew I could not. Over the time that I was left like this (30 to 60 minutes) I went from curiousity, to annoyance, to intense arrousal, and finally to that state of perfect submission and openess. I was open and ready for my Master, but I had learned obedience and control of my feminine muscles.

From that point on, he could ask me to halt and stay in the middle of his sexual use of me and I was able to obey and adopt the mental and sexual attitude of readiness and openess, awaiting his lead always.

Initially I didn't understand what the Master was trying to achieve with this training and maybe it was important that I figure it out by myself. But it certainly led me to a different attitude and dynamic within the cybersex. I had been very much feeling that I had to instigate, contribute all the time. This trained me to receptivity.
