oh yeah there's still a response to my fingers. I think the brush is more successful because of the speed and vibration. It provides a much different sensation that is impossible to resist lol.
I just love having her stretched out on the bed and bound up so that she knows there's no way she's getting loose. Watching her toes curl when she hears me testing the brush. What else can she do? She knows it's coming and there's nothing she can do about it. I get a lot of complaints about my use of gags in my videos but I find them important. The gag further reminds her that I'm in control. I decide what position her body is in when i tie her. I decide whether she'll be able to move her toes or if I'll tie them back in an uncomfortable position. And I will decide if she will be free to talk or if she'll be muffled with a gag. Heck I've been known to gag her with a sock right off her foot. It all lends to her realizing she is helpless....and that makes her vulnerable to being tickled sensless.
