looking for an old story

i really love sensual/sexual tickling....I'm talking about teasing or light tickling. Like tracing a feather on her back or nape. I'm not into torturous tickles.

I'm looking for a story with a bound woman. Then a tickler teases her...From her foot up to her neck..Then when she will be tickled on her neck, she blurted out something like(while gagged)...

"Shit! He knows my spots"
"He's going from my least sensitive/ticklish parts to the most ticklish parts"


Or something like it...Pleeeeaaasseeeee.....I forgot the title of this story...I would be very very very happy if someone remembers this story..Please reply...
