Foot Bitch

Apparently, men love to touch women's feet. This isn't some huge secret that I just let out, however some men seem to be more direct about their love of feet.  DocFS is pretty straight to the point...unless I'm missing some other sexual connotation? DocFS writes:
DocFS: Any chance I could, um...be your foot bitch?
Quick and too the point. But dear Mr. DocFS you can't just ask to be my foot bitch! There's a whole interview process and back ground check. And believe me, you'll never get anywhere near my feet.
