The polls you set up are like this: what part of your body do you most want to keep: your eyes, your mouth, your heart or your lungs?
How are we suppose to choose between these marvelous specimens of tickling glory??!! You are cruel, dear Tummy, simply cruel...and I won't choose...you can't make me!! No, no....
Welcome to an old, old thread, tklphile. I'm not sure what a "perfect body for tickling" means. If you said, for example: Hey, there's a perfect spot for a picnic, presumably there would be plenty of space, well-groomed grass, it would not be too hilly, have some sun, some shade, etc. So what does Jessica's body have that makes it easier or more effective to tickle than other bodies?
Or do you just mean that you think she has a perfect body? Hard to argue with that!!
