When we started filming Flexible Positions, the first girl that came to mind was Audrey Bitoni. If you haven't seen her big tits in action before, she's a petite brunette powerhouse built for speed and stamina but she still has really amazing flexibility as well. We let her work-up a sweat on the universal machine and she does some sexy grunting with free weights in her hands as well, before laying back over the pink balance ball so we could start pumping her with some Iron of our own!heck out the full video at Flexible Positions!
