Open Question: How to get a girl with a slight foot fetish let you massage her feet (no mean off topic answers or comments)?

[feedcrawler]

So my best friend has a slight foot fetish and I do to. I want to massage her feet because she has the cutest feet I have ever seen. I know that she would possibly say yes because she also has a crush on me and I have one on her (not asking her out tho... I'm too lazy to put why), but how would I ask her or should I just do it playfully out of nowhere since she likes that stuff a little? (Once again no mean/off topic answers or comments please) thanks.
