15 Challenge

My 15 challenge comes from doflodares. The challenge was once again, 100. Mistress had me do this challenge starting at Midnight. It is a good thing that I still have lots of concentration at night. I am more of a night person anyways. I was able to do all 100 with-in one hour. Mistress wanted me to go fast this time. Good thing I had my concentration. Going fast does mean I need to be ready at any moment once I reach the edge. With each edge coming faster and faster, each and every time; I was able to retrain myself from cumming. Towards the end, I thought I might cum; but with all my mediation techniques plus with my concentration I was able to reframe from cumming this time. Another nice challenge that I was ablet to do. Maybe next time.
