"Haley I'm back! Everything OK?" I heard Alexis's happy sound. Haley turns back and surprisingly says, "Oh honey, why don't you wear shoes? Do you go out barefoot?" Alexis naughtily says, "We have a good foot cleaner, why do I still need shoes?" I'm quickly scared and think, "Shit, will she ask me to lick her dirty soles?" I try to raise my head to see, and Haley feels my action. She gets up, takes out her socks and says, "Wow, come on Alexis, he can't wait to lick your dirty soles!" I want to flee, but she presses the chair, and I can't move a bit. Alexis sits down, put her feet near my eyes and says, "Really? Then let's start. First look at my soles very clearly, Brian." I look at her feet and find they have been black, dirt and soils are stuck in the skin especially heels and fore soles. Some parts are darker than others, I think they are callosities. Alexis grins, "Now start, I give you 10 minutes to lick my soles clean. Now it's 9:30 a.m. If you can't finish, I'll help you." I feel sick but have nothing to do. I put out my tongue, lightly touch her left fore sole. Fortunately it smells not too bad, but only looks disgusting. I slowly lick her left sole, Alexis makes some comfortable moans and encourages me. However, after some time I find I can't lick the dirt out, the skin only gets wet but doesn't get clean after I lick it. I quickly understand it's because my tongue is dirty. I spit out some saliva to clean my tongue, the dirty fluid flows out my mouth and pass through my face, then drops to the ground. When I lick to her left heel, she says, "Slave Brian, you only get 4 minutes left, you have a whole right sole and 5 left toes, I think you can't finish. May I help you?"
