Did I??? Oh yeah!!!
One person I asked, in a roundabout way, was my ex-wife when we were first dating. I would give her quick tickles here and there, and got quite nice reactions! So, one evening after we had been dating for a couple of weeks, she was at my house with the usual necking and me getting my usual tickles in, I asked her if I could tie her up. I wasn't too sure what she'd say, but she agreed! She had to know what was in store for her, but she was willing to go for it anyway. By the way, she turned out to be one of the most ticklish women I'd ever tickled, too!
So I led her to my torture chamber, I mean bedroom!

She was wearing slacks with pantyhose and loafers with a button up shirt on. I had her lay on her back with her feet hanging slightly off the bed where i tied her ankles to some "decorative" rings I had put on the sideboards of my waterbed about two feet apart. Then I went up and tied her wrists to some more rings at the top of the bed. Once she was totally helpless, she appeared a little nervious so I assured her that she was safe, I wouldn't hurt her in any way, and I think that made her feel a little better.
I then went to the foot of the bed and sat on the floor between her feet and slowly slipped her left shoe off. Of course I got that sweet sound that you get when nylons and leather rub, that little "shoosh" sound.

Then I started to slowly stroke the sole of her foot. She was trying her hardest to hold in the laughter but when I said "tickle, tickle, tickle, she repeated it and burst out with laughter! YES! Her ticklish body was mine! I tickled that foot for about 5 minutes before I stopped to let her catch her breath. It took her a couple of minutes to stop laughing. When she did, she wasn't the least bit mad and seemingly reading herself for more!?! So I loveingly obliged, and went for the other foot. I played with her insainly ticklish feet for quite some time. Then I figured that I should give her a break. So I stopped tickling her feet and got up from the floor and climbed onto the bed and straddled her waist. I unbottoned her shirt and spread it out away from her body and tickled her tummy for a bit. This, of course, got her laughing again, but I was just warming her up for where I really wanted to go. Those insainly ticklish pits! Now, up to tonight, I had never tickled her armpits for more than a few seconds, but they were off the scale ticklish and now I had her right where I wanted her. Instead of diving right in, I decided to tease her!
😱 I started to wiggle all ten fingers over her pits while I said " look at those poor exposed armpits, out there with no defense at all". She started giggling and then I said "look, so close". She said "oh noooo" and closed her eyes. I said "look, closer". She started laughing before I even touched her! But when my fingers made contact, she screeched then started laughing hysterically. I kept tickling around those pits looking for the worst spots.
After a while, I slowed down and began getting romantic while still lightly tickling her. We finally made love and all was good. I figured that that was my best chance I'd ever have to get her, but the very next time she was over, a few days later, she asked me if I wanted to tie her up again!

Ohhh kayyy. And so our life went for about 6 years until she slowly turned into the bitch from hell and we divorced. Oh well, life goes on.
