Quite frankly, I'd go about making you learn to love the cane with stong tones of domination and submission.

Talking to the submissive within, making you need to please me....


AND I'd make the bottoms of your feet a hard limit. (Mine if not yours.) You should never go through that again. First, you may have coped and can walk again, but it is unlikely you are "undamaged" physically. You can't assume, even if you can bear it, that you can take another trauma to your feet.

Why risk your mobility? I think that would be foolish, even for a single swipe of the cane. (Note, my answer would be different if this were merely fear. But you've stated you were in rehab. No way, no how, never again.)

There are plenty of ways to push you that don't have to put you at risk.

There are plenty of exceptionally painful places that you can be caned, besides the buttocks, that can be substituted when it comes to pushing limits.
