In my humble opinion ... this extensive collection, although impressive, best demonstrates the failure to differentiate between true sidewinders (assisted, unassisted, stereo and mono)and side boob shots!
This issue has been addressed at the beginning of this thread, but there is a fine line between a mono sidewinder and a side boob shot. A true sidewinder provides us with a full back/ass shot. When the model turns her head slightly and exposes the back side of her breast ... this is a mono sidewinder. When she turns so that you can see her nipple, this is really a side boob shot.
Am I wrong? :dunno:
