No, clearly Hutch did not/does not want Vivian to sleep with Christian for any reason. The bits that you are either trolling on or just skimming and not seeing all the detail of are mostly around the humiliation. It is clear from Vivian's expressions and reactions that she is not happy with the situation. At most, she is allowing herself to get lost in the moment, but as soon as her thoughts turn to Hutch, she feels guilt and shame, hurt and anger. There's literally nothing that suggests she enjoys humiliating Hutch or wants to humiliate him. She is not doing that intentionally - she is doing something that can be seen as humiliating Hutch, but that is a side-product of what she is doing, not the intended result. You can go into something knowing that someone will get hurt as a result, but that doesn't in the slightest mean that you are going into it to deliberately cause that harm.
The "talking code" bit is pretty nuanced. It's not about lying because you think you can keep the truth from the other person. They both know that the other person knows everything, but they're ashamed or afraid to openly admit it. If they do that, they will end up talking clearly about it (rather than in code), and it's like it will make it real. At the moment, they can still pretend that it isn't really happening, that it's all just a bad dream. They're both just lying to themselves to prevent opening that wound publicly, thinking it will be the less painful path for their partner.
It's like having that conversation with someone and it's a bit embarrassing, and you say "I've got a friend who..." or "hypothetically speaking..." and the other person knows full well that it's actually you you're talking about, that it's a real situation and not a hypothetical one, but they go along with it because it's an unspoken agremeent, a way to discuss the sensitive subject without pointing any fingers or causing any embarrassment.
The other stuff you keep talking about, going back to humiliation, but also around wanting to turn Hutch into a cuckold etc., there's just no indication of that whatsoever in the game. That's presumably just your wish fulfilment, because you like to see that, or you like to be cucked and humiliated. Either that, or it's because you're not reading the game in enough detail to see past your initial preconceptions. We'll see what the rest of the game has in store, but so far, there's literally nothing to suggest that's what's happening here.
