I'm sorry, but I cannot agree with this at all. If you thought the MC would be calling the shots once he joined the Club, I don't think you were paying attention.
I'm not saying he should be able to run the show, just that he has the ability to refuse to do stuff that isn't his job. Which he very clearly can do, because we see him do so at a later date. At the absolute very least he should be able to say that he never agreed to do anything like that, and then have her chastise him for being naive enough to think that he would get paid so much for so little. Then either her or Chuck or Killian could convince him to go through with the work.
The game just doesn't set up this scene properly. The conversation she mentions is something that never happened. The main character suddenly deciding to throw all his very reasonable concerns away the second they offer him money that he doesn't desperately need, is quite lame. It's not like he lost a bursary that was helping him pay for schooling and had his rent suddenly go up and is now desperate for money. His only complaint was that he didn't like tutoring and wouldn't do it if the pay wasn't so good.
Sure, he can choose to do it if he wants to, but you'd think that he'd be a bit more cautious about it what with how his mother's previous sex work has come back to haunt her all these years later.
Like TD said, the MC sold out his conscience the moment he learned Rose was sent to have sex with him purely as part of her interviewing process... and still took the job.
Imagine you get an office job working as an accountant for a mining company, and one day the boss comes in and tells you that you need to go down into the mines and dig coal with the other workers. You refuse because it's not your job, and he says the it is because you tacitly agreed to do it because you didn't object on moral grounds to all the other people work do the dirty work down there so you must therefore be also willing to do it too. You'd say that was bullshit too, because it is.
They tell you what your job description is, then after you reluctantly agree to it, they change the terms of the agreement and then the main character just pretends that they're not lying when they were told that they agreed to do it in a previous conversation that never happened.
Plus, on the specific topic of the MC objecting to whipping it out at Kathleen's command, it feels like a preposterously hypocritical take.
Why? What's hypocritical about it? Has he ever said that the other girls there shouldn't be allowed to refuse to do things that they never agreed to do? There's tons of jobs out there that people would never want to do in a million years, but are fine with other people doing them. If you hate the sea and can't stand the smell of fish, is it hypocritical for you to think that other people should be allowed to become fisherman if they want to?
