Whole lotta "it depends" here......first off, does the 'ler dig it, and does the lee dig it? Also, is the lee too ticklish for worship? I personally find that hot, so the key there is to massage the soles first, so the nerves are accustomed to touch, then start slow with the worship. The lee also may dig ticklish worship/lickling, so that's a factor that may be remedied with consensual bondage. Worship is more personal and intimate than finger/tool tickling, so the mindset is different. If you have a "tickle friend" with whom you're not "with" yet, worship may be perceived by one or both parties as taking it to the next level. Then there may be lees who are only somewhat foot-ticklish BUT they get extremely turned on when foot-worshipped. I've had "playmates" like that.
