Great to hear that - I enjoyed every single second of your game so far (although I would've loved to see the erotic scenes be more protracted and detailed along the lines Mister_M suggested earlier) except for the last too days when Mistress Rosemarie's little dog suddenly becomes Chad McChadson literally overnight!
Basically, I'm glad to hear you're already changing some things about that and making plenty of choices with a sub path - I think it could even be realistic for the MC to originally have an outburst where he wants to stand up to his bullies as he does in the current version, (especially if you write a slightly longer thought monologue where he contemplates how not having a backbone ruined his life/made him as passive and depressed as he is) but when he confronts Rosemarie in their last interaction and calls her a bitch, she takes him by surprise by slapping him hard and painfully in the face and responding with mockery (something like "aww, is my little doggie learning to bark? But bad dogs get punished and put in their place! Then again, given what happened two days ago, maybe that's what you actually crave? I wonder how many kicks to your crotch till you come this time around? <giggles>" - obviously that's just some unrefined spontaneous crap I came up with but you get the jist of it), after which you will eventually get a choice to remain defiant and intimidate like in the current version, or waiver as you start thinking more about your past respone to her ballbusting and your lewd dreams about Alex, and if you'd pick this MC would still originally argue that what she's saying is nonsense but with less conviction, and as she'd see it on your face she'd slap you again/kneecap your balls and mock you for lying to yourself that you didn't enjoy being tortured by her, after which you'd eventually become speechless and very indecive (because your character is baffled/scared that she sees right through him and challenged him so directly even when he thought he was being intimidating) and at the end of the scene accept to kneel to her to apologise for your disobedience, potentially even being given a punishment such as having to swallow her spit for making her talk too much to put you in your place.
Obviously you might've already written a lot of the next version and have other plans about how to make a submissive route separate from the dominant one (maybe already with renders done), but it's just an idea that came to mind as to how you can salvage all of the current content and still have the MC stay a submissive! (especially if he's tried and failed at standing up, that could make him feel ever more defeated and thinking about why he feels aroused by all of this...)
Finalement, j'aime ce petit jeu et mon personnage preferee jusqu'ici est Maitresse Rosemarie, mais toutes trois sont tres jollies! Bon travail!
