Hmm, actually she is always second in command, not really the boss and she has to jump through a lot of hoops to get and most important to stay there.
At the escort service the boss is Steve and Monica has to be successful not to be replaced, not only by Maley, but all the other girls. This makes her vulnerable.
At the Shiny Hole the Boss is the Bank Manager. Now she has to implent a lot of lewd stuff and Joe is still spending the business money on Claire. This will most likely lead to complications
Yes, she is back in her house, but she becomes more and more a servant for Fred. We can asume that Fred will exploit the new sex drive of Monica, maybe he will even drag in Julia, because he is involved with her too. Don´t forget that.
In my opinion it is a smart move of DM to drag Monica into lewder stuff through the motivation of possible success. It makes the situation more plausible
And it will make her willing to accept much more lewd involments.
But in fact the "promotions" only drag her deeper into trouble and the line between Monica and her aliases blur more and more.
I´m really looking forward to future updates too.
