It would be great if you uncovered her nipples and allow tickling there + upperbody would be wonderful, as well as (not sure if these are already a thing) different reactions between sole vs. toes, circles vs. up-and-down motion, fast vs. slow tickling, and I always focus on one toe at a time with the rope and toothbrush, she usually goes wild pretty quick if I focus on like her 2nd toe or baby toe lol.
I tickle one girl irl the time and focus on one toe at a time with all 5 fingers and drives her crazy this game is great for practice and new ideas :)
