I personally don't know any woman personally who is "into" being tickled, tied up, or otherwise indulging in tickle fantasy/fetishism. I do like the idea, though, of wives/significant others who are tickle-tricked or "accidentally tickled" as those are very realistic possibilities of happening.
The whole "burglar breaks in, ties me up, forces me to watch him tickle her" isn't realistic. But the "she had an ant on her bare sole and the neighbor brushed it off and she giggled and said 'thanks, that tickled'" is very realistic.
Happy to share/trade stories/scenarios like that.
