Perhaps it's that you're panicked to the point of foolishness, but in your current predicament, you decide that the only way of waking Erica (that would not risk passing her off) is to lick her feet!
Hating the fact that you feel you are being forced to do something so disgusting, you slowly extend your tongue out until it gently prods against several of her toes. As before, a sharp, cheddary flavour overloads your senses and makes you splutter, though only slightly. Dragging your tongue downwards, you brush it along the soft skin of Erica's sole, pushing it out further so you can cover more of the skin in one go.
Your cousin grunts; has she woken...? No, of course she hasn't! Deciding to press on - literally in this case - you lap your tongue out with more vigour, absorbing all of the unpleasant, bitter flavour that Erica's powerful soles have to offer. You pause, mid lick, hoping that there will be some stirring, or sign that she has started to wake. But nothing! In fact, she starts to snore a little louder, the rumbles shaking her body ever so slightly, forcing her feet forward a little, into your unwelcoming, helpless face.
Knowing you have to make your foot licking more pronounced, more clear, you resolve to make more of an effort! Flicking your forward so that her soles arch back slightly, you swish and swirl your tongue around, desperately, in order to wake her up. The rank taste of her feet is bouncing up and down your tongue, forcing you to moan and gag a little automatically. Still, you continue, pushing and forcing your tongue to lap up as much of her feet as you can conceivably manage. There seems to be no foot sweat now; that's already been absorbed by your mouth and now swallowed reluctantly. The very thought of that makes you cringe - so does the fact that her feet still taste horrendously awful!
Why won't she wake up? Surely anyone else would begin to awake from their slumber with their feet being licked at this velocity?! You dearly wish that she would just snap out of her dream! Is it even worth continuing with this foot licking torture if it's proving to be completely ineffective? You pause for a moment, your tongue practically stuck to the middle of one her soles as you consider your options...
