Depending on the skill of the Ler, most of my body is borderline unbearable. Lol
Enough to keep up that deep, steady, laugh. Then, it quickly turns hysterical when the intensity is turned up. 😱
My wife is very ticklish. Underarms, feet, ribs, hipbones, when tickled will bring out hysterical laughter and will typically cause her to use her safeword.
Her ears, however, while very ticklish, can tolerate tickling for awhile, and while she will laugh, she can take it much longer than other spots.
