The Rehab
Hmmm....ideas for The Rehab part III....
Well, it sounds like it would mainly consist of the husband getting more treatment. I would suggest you keep the same style of female ticklers, and DEFINIITELY the same type of dialog!
One idea I had would involve a sexual addition to it. Maybe part of his rehab is to be forced to cum, and then immediate tickling afterwards. It's common knowledge (at least on this forum anyway lol) that males are much more ticklish after they cum. This would increase his sensitivity, and perhaps also could be training for him to think cumming whenever and however he pleases is a bad thing (like some psychology of associating sex with tickle torture or something to that effect).
I have a lot more ideas as well, but I figured I'd start with that and see what you thought.
