You guys need to check out these AWESOME NEW shiny black leggings that I just bought! They are definitely the shiniest I have ever owned! Something you should also know about me is that I like to bounce my butt cheeks. However, it's been awhile and I decided to flex them. Also, the tightness of the leggings kind of made bouncing impossible anyways. My ass cheek moves as I flex it over and over, the shiny material clinging to me like a second skin and reflecting the light in various ways. I switch which side I flex a couple times so that you get a full show of butt flexing delights!
