This frame is a MetalBondage.com classic! Bending over a bar, neck attached to the frame, it is a very nice position… and quite a predicament for the lower back! I was enjoying watching Cindy Dollar in this position when I noticed she was pulling back a little from the frame. The best way to change that is to add a pair of clover clamps with a weight on it. You can see what I mean if you study the picture set and the video. With her sensitive nipples clamped, Cindy was moving less and bending over more! Perfect!
she is slouching and not keeping her knees straight, I’d add an anal hook
