More foot fetish talk...getting wife's permission to give foot massages

Hey everyone,

I just posted about a friend who I had an arrangement with. Basically I would do things for her and in return she would let me rub her feet. In short, I ended that arrangement and she was totally cool about it. The main reason is because my wife doesn't want me rubbing other women's feet. My quick question...does anyone else have a fetish or trigger that their wife knows about and allows for some level of "blowing off steam"...for example, if my wife knew that I loved only her, but allowed me to give foot massages in exchange for knowing I would never think about watching porn or cheating on her, etc. Does anyone have that type of agreement in their marriage or relationship? Thanks!
