She gives many ticklish reactions, mentions that it tickles and that she's sensitive pretty much throughout the entire first video.
Her armpit gets tickled from 4:07, and then she gets tickled on her ribs and stomach constantly for about ten minutes mostly with the stainless steel tool and then with fingers from 13:27 till the end:

I didn't watch the entire second video (don't have the time now), but her inner knee gets tickled at 3:37:
