I'm primarily a ler, not a lee.
When we were dating my wife had an intense orgasm
while I was tickling her feet, but it wasn't from tickling alone.
I was stroking her breasts and giving her some "oral attention" (hey, we got young folks on here!) Anyway, I kept both of these things going, and used one of my hands to softly stroke her inner thigh and then down her leg to her left foot.
I began to stroke the sole lightly, and then switched to a very light spider-tickle. All the time this is going on, I continued the combination of "oral attention", nipple-tweaking and light massage of one of her breasts. As soon as I began spider tickling she moaned something like "Oh my God! You can do
that at the same time!" At that point she started babbling and got pretty incoherent.
It took her a few minutes to come back to reality.
