Hehehe, I have a bunch of lickers in my house! Cash goes into a trance licking anything he's able to put his mouth to, including my hands, feet, legs, etc. LOL! He sometimes licks me so hard that I can feel his teeth scratching my skin.
Your story made me think of my Biewer, Orio. He loves licking my feet after I get out of the shower too. I don't know if it's the warm water, sweet smell or saltiness, but he loves it. I can only stand it for so long - it tickles!
