Mistress Avery is a cunning girl. She wanted this guy to lick her feet. But she knew that if she asked him to do it, he would not do it. She had to come up with a new way of doing things. So the mistress chose to tease him and then tell him that her feet were her g-spot. And that if he licked them, he would turn her on massively. He did it and she enjoyed it but she did not get turned on.
