She pulls you in close, and says, "Day in and day out, I'm on my feet behind the bar serving drinks. As I'm sure you've noticed, the get good and sweaty. I don't like having sweat between my toes, so do me a favor, and clean it out for me."
Still gripping you with her left foot, she raises her right foot to your head. You open your mouth, and she shoves her toes right in.

You stick your tongue out, and she drags her sole across it, heel to toe.
Once it's all clean, she grabs your shirt with her clean foot, and shoves the sweaty one right into your mouth. The same process follows. Tongue between toes, and then it's used as a doormat. Once both feet are clean, she pulls you onto the couch, and lays her feet in your lap.
