17th Challenge

This Challenge came from iSpuds. The challenge was 73. This time Mistress thought if she where to turn down the heat and make the room cold; thought I would not be able to concentrate. My body is able to raise my body heat when needed to keep me warm. I was able to complete 35 in the first hour. I could feel how cold the room was, but it did not effect my concentration. I completed 33 in the second hour. My body now is feeling cold, but my internal body heat was still there. I finished the remaining 5 in about 15 minutes. Once again, the concentration techniques I know helped me each and every time from cumming.
