This would be something of a butt-appreciation vid. I'm thinking you could be scrubbing the floor, like in "Spongecrack HD", but with the camera in nice and close to your ass, about the same angle and distance as it was in "Juicy Fat Ass Shaking". If you could turn back and forth in a slow semi-circle while scrubbing, showing off all angles from side-on to full-on, that would be ideal. In terms of clothing, start out naked except for panties, which should ideally be white and full-seated, so not too much is revealed at first. As you scrub back and forth, reach back every now and again and pull them down an inch or so. Pacing-wise, if it's a ten minute vid, your butt could be fully naked at about the 7:30 mark. Slow and sensual movements are good. For music, classical would set the tone nicely, e.g. Clair de lune by Debussy, but it's okay to have no music if you don't own that sort of thing. If you could finish up with your bare butt pointed at the camera that would be awesome.
