This is why it's suggested that foot play should usually either be after a shower, or should at least start with washing the feet, first. I know that may seem impractical at times, but think about it: a lot of people tend to walk around their house barefoot. That includes the kitchen (for those who don't mop every week, ever get that annoying sensation of crumbs, or worse, that sticky, spilled liquid feeling when you peel your foot off the floor? For those that mop frequently, think about cleaning chemical residue!
), the bathroom (don't even get me started!), and the carpet (dust mites, dust mite poop, and dander and hair if you've got pets). The odd compulsion of wanting to lick is one of the things I hate most about having a foot fetish. Some stupid little voice says,
"Ooh, that looks tasty! I bet it tastes like a Reese's peanut butter cup, or maybe vanilla ice cream!"
I have to tell that voice,
"Shut up! You DON'T know what you're talkin' about!"
