Ticklish Girls - Nadia Topless and Tickled in the Stocks

We have tried this before with the same result.  nadia is not ticklish on her feet, and she does not have any reaction.  but she looks great sitting topless in the stocks, while i try the usual things to get her to laugh.  she doesn’t even flinch though.  she said she walks barefoot a lot, intentionally making her feet not sensitive to anything.
