I really liked the Kiara/Eileen and Megan scenes the most. The lunch/dinner scenes were alright, but they didn't feel too different from similar scenes we've had in the past. I'm not saying I dislike them, but I'd say maybe having something to set them apart from previous scenes wouldn't hurt. If I think of anything I'll let you know.
I didn't really dislike any scene in particular, however, I will say I wasn't a fan of the fact that all three Maddie scenes are just the same with different outfits and dialogue. Also, neither were really
maledom or
femdom, the Maddie submissive route was just pet-play. And the Maddie dom route, which I kinda just skimmed over, was the lightest femdom imaginable. Which makes me wonder if those routes are really worth it, they won't really appeal to fans of those kinks. The pet-play stuff doesn't need to be on a separate route, it could easily be added to the romance route as an optional kink. The 'femdom' stuff seemed so inconsequential, and didn't really fill the role of any other kinks either, that it kinda felt like it was pointless.
This is just my opinions on the matter, I want it to be clear I'm not demanding, or even asking you trop, to change/remove anything. I'm simply providing my feedback, and you can do what you want with it. So... my advice/feedback would be, at some point, get rid of Maddie's 'dom' routes, and keep the pet-play kink stuff and add it as something optional on the romance/regular path. Again, the femdom stuff just seems pointless, won't really appeal to femdom lovers, it's way too light, and therefore it seems like extra work for no payoff. (I know it's the first scene of it's kind, but pretty sure you already said it would remain really light) You might have a few people who will enjoy the really light femdom stuff, but not many I imagine.
Whereas, pet-play on the other hand, is a kink that stands on it's own, and it was actually not bad, I enjoyed it quite a bit. Pet-play, and other types of roleplay, even those associated with BDSM, aren't always dom/sub scenarios or dynamics. Discipline is another aspect of BDSM, which can work hand in hand with pet-play, and it doesn't have to involve a dom/sub dynamic or pain or bondage, nothing of the sort. Punishments/rewards is quite a common thing within pet-play, where you can roleplay out things and depending on if Maddie does good or bad, can get spanked or put in timeout or something, or she can get a reward... whatever that reward might be. There could be "training scenes" where the MC teaches her a couple of tricks for example, and that would be a good time to reward her if she does well. There are many ideas you can come up with for this.
Anways... that's all I have to say for now, If I think of anything else to add I'll come back and let you know! I hope my advice helps you or gives you at least somewhat of an idea for something! If not, that's fine too, I'm just here for the ride.
