consentual
Guess I'm not cruel enough...
But like DarkKnight, an angry ticklee is a real turn-off for me.
I've tickled my wife's feet, mostly non consentual, but mostly its just quick tickles I give if she's going around the house barefoot (and always is), or sometimes when I massage her feet. She's overly ticklish. However, I couldn't, and would never lock her in a pair of stocks or tie up her feet for tickling. The outcome of that would be, at the least, no tickling or sex for a very long time.
Like Johnny Radical says, respect all females.
