Revenge
You get to the edge and both women down the drinks your prepared for them.
LISA: I can get used to this kind of service.
CARRIE: So can I. I'm a little jealous (giggling)
LISA: So you like to have your feet worshiped, huh Carrie?
CARRIE: Oh God, yes! I love it. That, followed by some oral attention is all I really need to get off. (She then realizes she may have said too much to Lisa and looks at her apologetically).
LISA: You got it, my friend! Today, my submissive husband's first duty to me, his dominant wife, is to please you they way you want. This will be perfect because it's the only thing, and I do mean ONLY THING, that he is any good at or any good for. Joseph, my little perverted cuckold piggy, worship Mistress Carrie's feet for her. NOW! Clean her boots first.... With your tongue!
You pause at first but then think of the faxed signed agreement. You slowly crawl over to Mistress Carrie's feet. Her boots are so high. You crawl under her chair and begin to lick her boots
CARRIE: (Looking at Lisa and smiling in amazement) Are you sure you're okay with this?
