Yeah actually, this dorky girl back in high school.
Back in high school, I used to sneak up behind girls I knew (not really friends, but on speaking terms), and tickle the hell out of their sides and stomachs. A couple liked it, a few hated it. There was this one girl, kind of a geek, but ok. Well, when she was walking down the hall with one of the other girls I tickled, I tickled the geeky girl, as the other one was expecting it. She was DAMN ticklish, no real laughing, but a lot of squirming and trying to get away. I didn't expect much after that from her, but after a few days, I found her sitting next to me, talking to me, and sometimes positioning herself where it seemed like she left herself open for a tickle.
I kept tickling her, along with the other girls, and she kept talking to me. I had never known her before, but now I had found myself talking to her a lot, thinking she was liking the tickling. So one day, I do the whole "wanna see something funny" thing and ask to see her foot. She had to have known what I was doing, not a minute before I had tickled the hell out of her sides. But as soon as I asked, she knocked off her flip-flop and eagerly gave me her foot, which I tickled and she laughed loudly and giggled. Now she knew damn well what I was going to do to her, and she had a boyfriend, so I'm pretty sure she didn't think I was flirting with her. Until the end of school, I tickled her along with the rest of the girls, but she seemed to like it a lot more.
