mine was late--I was 19 or 20 when I started dating this girl. She always bragged about how nice her feet were, but it was winter and she wore boots all the time. One night we were watching yet another Vikings defeat in primetime, and we started tickling. She had socks on, and when I threatened to take them off, she said "go ahead, I dare you." So I did, and she was right, she had really nice feet and they were really ticklish. I got her for about 10 seconds and gave up, because I didn't want to "out" myself. Turns out she liked it, which lead to many more instances where I tickled her feet. Too bad she wasn't very nice otherwise, or we'd still be together. I have plenty of stories of her letting me tickle her if anyone's interested. I'll post them in the story section if you'd like.
