I know this is an old thread, but I have recently been pouring through some of these "competitive endurance tickling" videos on the video sharing sites on the Internet, and I came back to the TMF to look around to see if anyone here had talked about it.
It also struck me as strange that the owner stressed that it was definitely not "porn" or "fetish" related, but still wanted very attractive, athletic-looking guys to audition. And if I remember correctly, she wanted only guys between 18 and 25 years of age.
I've watched a fair number of the videos, though I've only watched the f/m videos. She's also made some m/m, and I'm sorry, but I just can't watch that. I can watch f/f, and I feel like a total hypocrite for it, but whatever. I've actually liked most of the f/m videos I've seen from this person. Some of the guys aren't quite as ticklish as they make them out to be, but the female lers are pretty cool. One thing that strikes me, though: the female lers, for the most part, seem very serious about this whole thing. They'll sit there on the bed with a solemn expression during the whole video while they're doing their "work." Not all of them are like this, but many of them are. It's like they're performing surgery or something. How can you sit there all stone-faced while you're tickling someone?
I won't lie. I have entertained thoughts of auditioning for this. However, I would quite certainly be rejected. For one thing, I am outside of the age range. Also, while I'm not a fat guy, I'm not really athletic, either. However, if I applied and was accepted, I'd be tempted to go ahead with it. If I got shafted on the payment, I could live with that--as long as I got tickled by an awesome female tickler.
