Bondage comes in so many forms…all of them are fun, but at the ultimate end of the spectrum is absolute total restraint. Taking away every ability to move is a transcendent experience that cannot be described.
A good test is to tell your bottom to relax, and then snap a picture. Then tell him to struggle as hard as he can, and take another picture. If you can’t tell the difference between the two, add some electro and crank it up high…make him howl into his gag…and snap a picture of that. If you still can’t tell the difference in the photos, you may have used the right amount of bondage.
However…just to be sure, and particularly if I am the one you have bound, don’t stop just because you pass the “photo struggle test”. Keep adding the straps, ropes, restraints, wrap, tape, and anything else you have on hand that will increase immobility or provide additional security.
