...Instead of starting the girl off in the stocks, have her be a regular person. She doesn't have to say anything, just have her wake up and get ready for work. Maybe she calls the tickle at home service, and they'll be there that afternoon. She can walk around the office all day in shoes and sometimes in hose, in anticipation for the afternoon. She gets home, the tickler shows up, the fun begins. The camera could be under the desk as her foot dangles back and forth, and as her toes wiggle. She could be seen at a desk, walking to er car, getting out, climbing steps, etc. (maybe in her house climbing steps with no shoes on.) She can start off with hose, and later they can be removed for the barefoot fans...
People like to see the girl next door type tickled because we can actually believe they will be tickled. A model who is already sitting in the stocks in a bikini top is a model! We subconciously say "She did this for the money, she's may be enjoying this, probably not, but she's just thinking "This is dumb, where's my payment..."...
