My apologies in advance for bringing up a topic that's probably been discussed here a hundred times, but if one is trying to foot-tickle a lee with only moderately ticklish feet (sometimes smiles/laughs a little, other times not at all when her bare feet are tickled with fingertips), what are some of the best ways to get better results? Hairbrushes or a Sonicare as seen in some of the videos? Baby oil or lotion? Pantyhose as opposed to barefeet? Any advice will be tried and appreciated! 😉
