I don't know, but one time there was this college girl and I used to massage her feet, and it was a platonic relationship. At that time I was...let's see....thirty, and she was about twenty, so not that much older, but I did feel that she was like a kid. I met her because she was around, I worked at my friend's store and the university was there and all kinds of college kids came in. She hung out at the store, as a lot of people did, as it was a laid back place; we sold music, CD's, incense, books, all kinds of cool stuff. Her name was Amy and she would invite me over to her place for dinner or to play Frisbee, etc. She had a boyfriend who I met, and he was a nice guy. But Amy seemed to have a foot problem, and had this weird prickly thing she used to massage her feet with, by herself. It looked like a plastic porcupine or something. So I told her I could massage her feet if she wanted. After a while it became a ritual; she'd cook me dinner, and then it was "foot time". I eventually told her I had a foot fetish but she didn't seem to mind. But it was weird because she seemed like such a little kid to me, like a little sister in a way, and very innocent. But she really enjoyed it. She eventually graduated and moved to California.
I've had girlfriends who also enjoyed me massaging their feet, but with them I did more than just massaging, lol
