As a tickler...

[Emulator]

If you had to choose between tickling your tickle's most sensitive one or two spots, OR tickling everywhere else EXCEPT for those one/two spots, which would you choose? The experience would be different with each lee of course (level of sensitivity), but think of it generally of course.

I'd prefer everywhere except the worst spots, because it provides more of a challenge for me to make her surrender, AND I'd want the session to last as long as possible, so spending more time on the less sensitive spots would be more convenient as it still tickles her and makes her stamina last a bit longer.
