Ayn

I fully agree with you on the bondage aspect.
For me the fascination is the state of complete helplessness. With the riding crop you only reach my surface, but to reach my brain, I got to feel helplessness, which is difficult to achieve without being under physical control.

Having my hands chained to the back only for moving the 4 feet to the next equipment adds a lot to the excitement and feeling of helplessness. Once my wrists are secured behind my back, I know I am at the mercy of a 120 pound woman - particularly if she has a track-record of taking advantage of my vulnerabilities :-)
I don't look at this transition as "lost time", but rather as "fore play".

And of course, I had many good sessions, where the transition from one equipment to the other had the purpose of a one-minute break with feedback and water. And it would never have crossed my mind that it was anything else than that.
