I agree with MistressValerie. This is a completely awesome idea for a thread! As someone who has recently broken over the line into F/M fandom, I’ve been looking pretty hard for any fun, sexy F/M tickling stories. Here’s what I’ve found so far, at least the ones that haven’t been mentioned.
An unknown author story involving a poor private instructor at the mercy of his three vivacious students. Very sexy, very well written. The spanking scene was a little beyond me, but it’s rather small, and if you save it to a computer, easily edited out.

And a very sexy story by new author xylo over at the TMF. A young eighteen year old works at a birthday party for some sexy older women, who go a bit beyond the original contract. Very nice!

And now a request for a story I’ve had the devil’s own luck trying to find. I saw it not more than a year back, before I became completely comfortable with F/M tickling. It was (if I remember correctly) about a number of cat boys being tickled in a lab by some lovely scientists, before one of the cat boys broke free and returned to the love. If anyone could locate this story for me, I’d be most grateful.
