pumping gas...

I just got back from a public outing order my Mistress gave me. I had to pump gas while wearing my 6" high heel boots. I had to pump gas in heels before, but never in 6" heels and believe they are quite tall and create loud noise while walking on the hard concrete. However, I did it and I feel now very proud, especially as I didn't feel very submissive after my workout this afternoon, but I told myself that I have to do this for my Mistress and that she knows best what's good for me.....thank you Mistress!
