Open Question: How do I convince her it's not cheating if it's with her feet? 10 points?

[feedcrawler]

I'll keep it short Basically I have a foot fetish and I have a friend that I pay time to time to let me do things to her feet sexually, she's fully aware of my fetish. The thing is I want to do more with her feet but she's in a relationship and she says she wont let me do anything sexual other than what I'm currently doing which is kissing the sole of her feet, sucking on her toes, rubbing lotion on her feet etc.. I want to convince her to let me to do more things. How do I convince her it's not cheating if it's with her feet?
