Foot massages are very different from foot slobbering. I read somewhere that getting you toe sucked is the most similar feeling to getting ....... your male genitalia sucked that women could every compare. I said that funny but I'm sure you get the gist.
I'm not into feet like that, but i'm not all, EWWWW get your feet away from me either. A good foot rub after a long day of work is great.
