Being a submissive is a series of trust tests. My mistress knew that and decided to offer me a new experience. We had checked into a hotel, where she inspected me thoroughly, including me being played with, teased, and spanked. The warmth of the setting sun made me feel the joy of service, and wondered what was to come.
She had called me into the bedroom where I was asked to climb onto all 4's, sitting in front of her much like a dog or cow, with my single udder pointing straight down and my legs spread. What a humiliating stance. It was there that I discovered her desire to milk my cock. I don't mean the joyful pumping of one's member. I mean the stealing and releasing of an orgasm without the joy of cum.
I had just crawled up on the bed, gotten on all fours, when she sat down right behind me, and whispered to me "and now my little cock slut, I am going to take your one last control from you." She laid a small shot glass right below my cock, and thought she was going to stroke me until I came. Instead, she slid her two longest fingers into my ass. I could tell that she had put lube on them, because at contact, I tightened my ass, but her fingers entered rather easily.
At first, I felt that this was some form of discipline. She had often enjoyed playing with dildos in my ass, but never before had she ever violated my ass with her own two fingers. The discipline wasn't the point of this, as I was to find out. Her fingers began to slide deep inside of me, almost as if she were searching for something. It was a strange feeling to me. She caressed my insides, almost looking for a point to touch. I had no idea what she was looking for until she found it.
Suddenly, I felt her reach a spot inside of me that made my cock jump. It was pressure, and created a desire for me to urinate immediately. My erect cock immediately began to grow soft. She found the spot and begin to push and release, push and release, and with each push, the cock would jump, reacting to the pressure she was exposing me to.
Her pressure suddenly changed, to more of a rub along an imaginary line inside of me, like a path leading from that spot to the entry to my cock. And as she did, the desire to urinate increased. I wanted to release, but I also didn't want to pee right there on the bed. It was at that moment my mistress sensed my distress and said, "it is okay my little pet, relax. You won't pee, instead you will just release a little liquid for me. I will milk it out of you." I didn't understand what that met, but I took a deep breath and tried to relax.
