Being a ticklish male, I usually feel a little embarrassed when I get tickled in public, but I do get turned on when I see any tickling involving a pretty girl whether she's the 'ler or the 'lee.
This reminds me of a story from when I was in HS. There was this cute redhead, we'll call her Amy(not her real name) who was a real bad-girl. She hung out w/all the rough crowd(they used to be called "freaks" or "burn-outs" they were always getting in trouble, doing drugs, etc.). Back then I was dumb enough to think those losers were actually "cool". Anyway this girl had the most incredible bare feet, and she ALWAYS walked around barefoot. She walked barefoot all the time, even on hot pavement in warmer months, and it never seemed to bother her. I thought there was no way this girl could have ticklish feet, figuring she must have thick calluses from going barefoot all the time(even though her feet still looked cute). Plus I felt like she was just "too cool, and too tough" to be ticklish. Anyway since Amy lived fairly close to my neighborhood, she always on our school bus, driving me crazy w/her bare feet. Her friend Cindy(who I think was one of us, because she tickled a lot of people on the bus) one day tickled Amy's feet and Amy freaked out laughing and jerking her feet away. I managed to see the tickling although I tried not to be too obvious. Cindy said "Damn, you're really ticklish. All I have to do is touch your foot and you can't take it." I never forgot that, and at least 2 or 3 more times that year, Cindy tickled Amy's feet w/each time Amy laughing, squealing and jerking her feet away. That always fascinated me, how someone can walk barefoot all the time on rocks or hot pavement, w/no problem, but a little tickling drives them nuts.
Me being a high school nerd, never had a chance w/one of the "cool girls" like Amy(although I did talk to her years later at the HS Reunion, and she was actually a very nice young lady, much friendlier than I thought, although also very married).
Anyway long story short, I still remember seeing Amy's feet tickled after all these years, and it still gives me a little thrill. I just wished I had a chance to get at those sexy soles.
