Do you mean something like blindfolding, so the lee doesn't know where or when the onslaught will begin?
Just make sure it's not too tight, cutting off circulation is never good!! Especially not by the eyes, geez,
but anywhere!!
You did ask for a story.... Another friend required me to say a few things I'd really have preferred not to, as a safeword (or sentence...
) several years ago. And then used my embarrassment against me as well, because we were in a public place, though not too populated.
I had no idea he was a ticklephile, until it was too late & I was stuck under an arm & leg that felt like tree trunks... Face down on a blanket or towel. It probably looked like an odd hug... I guess it was... He didn't over do it, thankfully, so I was able to contain myself enough (to not make a scene, this was outdoors) but I was easily trapped at least a half hour.
(He probably suspected or understood I did enjoy that since I didn't start screaming bloody murder, though I did try to escape - there's always that contradiction, since tickling is obviously not bearable if you're affected... and it was somewhat public so that made me more uncomfortable... but he was smart & kept it gentle, again, just manageable enough.) I tried to use the "we're in public" angle to get free, but he insisted nobody was near enough, nor looking nor close enough to hear anything, and he was probably right. I was afraid to look, embarrassed at being pinned, and then tickled; if there was anyone in range I didn't want to draw their attention either, didn't want them to see my face... especially in case I knew them. That he saw too much of it was more than bad enough.
Later on he noticed I used a funny "feet" pic for a profile in summer, some Google image I thought was harmless or generic enough, and he "casually" questioned me about that choice. A few times... His unusual focus upon that as well pretty much confirmed he was trying to find out if I shared this interest, but I viewed him as more of a brother-type (most unfortunately) so I never told him. (He's married with kids now and probably forgot all about this...) I hope that fulfilled your request & love your signature!
