Depending on the ler and if he was tickling both my feet not very long. But I dont usually have a safeword because Im to stuborn to use them so it doesnt matter if I can take it or not Im getting it anyways
The longest (unfortunately) was about 5 minutes. I think I could easily handle 30 minutes, though I've never been put to the test ... still waiting for that one ...
I really love having my feet tickled. It is an amazing sensation.
I have recently opened my mind to different ways of tickling the toes, and new methods for foot tickling that give me tons of pleasure. I like it to last as long as I can stand it...but I don't have an exact timeframe. I guess my answer to your question would be that I'd like it to last as long as it feels good.
