Just lying down and playing on my phone with my butt out, flexing my ass muscles! I flex my ass cheeks individually, then together, with my legs together then with my legs apart! Get a load of my big, soft ass and thighs - you can even spot a bit of my ass hair when my legs are spread! This is something I do a lot when I'm wasting time on Twitter, so I wanted to turn it into a video lol.
