My 22nd Challenge

My 22nd Challenge comes from Slave_E, the challenge was 99. Mistress and Master both want me to stand while I was doing this challenge. I really don't like to stand while I do edgings. However, I did as I was told. I was only able to do 25 in the first hour. another 25 in the second hour. 25 in the third hour, my legs are starting to get tired of having to stand. I was able to complete the remaining 25 in another hour. It took extra patients and a lot more focus to stay standing while trying to edge while standing-up. I was able to reframe from cumming each and every time. After I had finished, I clasped on the floor. My legs where so tired of having to stand. I led there for a couple of hours until I got back the feeling in my legs again to move.
