(This was a custom clip based on the following)
A girl thinks she is being sneaky by crawling into her flatmate’s room to get a sly lick while she things she is dozing. The girl, however, is very conscious of what's going on and just enjoys the fact that her feet turns her flatmate on so much. 
The sneaky girl's favourite part is the bit between the toes as that is where the most flavour is and she licks up as much flavour as she possibly can, enjoying her flatmate's feet at a slow leisurely pace until she is totally satisfied.
