I too love this kind of reaction.
Last month, shane2 posted asking about the all-time most ticklish models. My reply highlighted mainly hot, hysterical, energetic lees. Here it is with links...
Fun thread! It's a little hard for me to focus exclusively on "most ticklish" exclusively, since other factors influence my favorites, but here are some greats...
- Kagney Linn Karter (FM Concepts) -- I've only seen her in FM-TH-66s1, but in that clip she may be tickled harder than any other girl I've ever seen while still fun (i.e. laughing/screaming/begging, not crying/miserable.)

- Dyan & Kimberly (Ticklish Montreal Models) -- Not as hot/sexy, but even more ticklish. Unfortunately it's purely the screaming variety, which isn't as hot for me as giggles and laughter with only occasional screams. Still, the reactions of these two are off the charts.

- Unnamed redhead in FOL-153 (Feet Online) -- Drop-dead gorgeous with totally spastic reactions.
((Sorry, can't find feet online! Guess it closed down))
- Lena (French Tickling) -- My #1 all-time favorite lee, overall. Unbelievably ticklish EVERYWHERE, but with perfect reactions showing she likes it!

- Jade (Tickling Studio) -- Possibly the most ticklish feet ever.

- Unnamed MILF in "Tickle Frigid" (Nylon Tickling) -- Extremely ticklish and absolutely cannot stand it at all. I love her helpless laughter.

- Isabella Janacek (FM Concepts) -- Kudos to MaleTicklerDC for mentioning her. Always one my favs, though she was never tickled hard enough IMHO. (BTW, Jana Cova, another Czech hottie, has almost the same laugh.)

- Unnamed cutie in "Tie Me Up & Tickle Me" (Nylon Tickling) -- She squirms and giggles like crazy but obviously LOVES being tickled.

- Michelle Bauer aka Pia Sands (CalStar) -- Deservedly famous from their first (two?) "Tied & Tickled" vids. Smoking hot, truly can't stand it, incredible!

- Crissy Moran (Tickle Central & others) -- My 2nd fav overall, behind only Lena. She's so hot and unbelievably cute, but in some clips not quite as ticklish (though in others she's incredible).

- Julia Parton (FM Concepts) -- Ridiculously ticklish MILF, but not as hot IMO. Wish she'd made more clips.

- Renee (Tickling Paradise) -- Sexy mature MILF who is just crazy ticklish in some clips.

- Trista Mallory (FM Concepts) -- Extremely ticklish w/ballistic spots.

- Britney Brooks (Nylon Tickling & others) -- Love her high-pitched screamy laugh!
