Ok, let's hear it. What do you have to say about her relation to and dealing with power?
Dylan93 here gave some relevant hints I think, but you won't like that post I guess.
Apart from that: For Vivian sex is obviously a power play, that's among the reasons the Sunshine and Rain escapade didn't do it for her in my opinion, there were no power levels involved, just a bit of roleplay if I remember correctly. She wants to sense real power in sex, and that's something she has detected in her sex with the boss, and that's something she doesn't sense with Hutch of course. But I don'T think (up to now) it's submission in the narrow sense she seeks with the boss. She wants to go with the winner and be dominant together with him. She goes over to the winner to win together with him. She wants to be recognized by the powerful one rather than just submit. She has to pretend she is an equal, she has to pretend she is empowered in the moment of objective submission, she wants to prove she is tough enough for him to go through the things he wants her to. Of course it is de facto submission and he knows it, but she wants to pretend otherwise. The fury she shows after the hotel is her getting drawn into a lustful struggle with the boss, as she sees it, to win his recognition, and this irresistible expectation lets her totally shove her husband to the side. At that moment she didn't lust for sex but for a fight, she thought she had earned a fight. The following sex is a struggle in whiich she wants to prove herself. It literally has characteristics of a struggle session.
In addition her relation with the boss gives her opportunities to assert dominance over Hutch openly and by implication and she does it with delight. She does so by talking about him with a manner of superiority and giving away his weaknesses freely to the boss. She constantly from the beginning of the whole story exhibits a protective attitude towards Hutch - some here, Tony for example, interpet this as genuine, I see it as getting into a dominant and belittling role: she protects the absent cuckold by putting in a good word for him with her lover. She rides the bosses cock in the car while crying out that she does this to rescue Hutch: her sexual arousal blends together with her feeling of power over her Husband she has his fate in her hand/pussy in that moment (a reenactment of the chapter 1 ssex). Her disappointment when she hears during the dinner that Hutch's job wasn't in danger is one of losing this role. Her insisting on being the one who has "the talk" with Hutch is also a power move: she can handle this/him (she says it so literally), it gives her a kick instead of embarassement and shame.
