Alexis quickly withdraws her foot from you. "Did you just..." she cuts off. You are just getting ready to apologize when she puts her feet right above your face again. "Keep licking," she says, almost as a request now, but you don't need to be told twice. You take both feet in your hands and lick up the length of each foot. The vinegar taste you never thought you'd enjoy leaves you feeling like you're in heaven. Her feet twitch and she giggles. "That tickles. Don't stop." Like you would. You continue to lick up and down each sole, taking in the strength of the odor and taste at each point. Alexis moans in delight. You begin to lick between her toes, where the sweat is still strong. The odor there hits you again, that delightful cheddar popcorn scent, as you wrap your tongue around big toe. You continue to lick her feet for what seemed like an eternity, but was probably only about an hour. Finally, Alexis, who seems to be enjoying this as much as you, pops her toes into your mouth and wiggles them around. "Just suck my toes for a while," she says. Obediently you suck her toes, cleaning all of her sweaty toes of the grime she'd gathered in those boots. You thought this would never end, but suddenly there's a knock at the door. Mindy and Jasmine call through the door.
