Ah Ok.
i would love the same position, but due to my subs knees she can not maintain that position for very long with out causing significant pain the following day... and making it very hard for her to keep up with a baby.
I current favorite is cuffed ankles, with a spreader bar between them, with straps to the anchor in the ceiling. Then cuffing her wrists to either the ankle cuffs or to an anchor above her head. All this while she is laying with her back on the bed, Allows access to all the fun parts and pushes her breasts out. Very nice, but with one problem.
She slowly loses circulation to her feet from having them in the air for long periods of time. Anyone know of ways to help with this, or is it just an unfortunate side effect.
