Hi friend,
I get your desire for more pages but that as you already guessed pretty much does more harm than good. In the discord with a lot of the other creators and especially the really big ones, they already questioned the amount of pages I publish for free on here. Since it diminishes the reason to subscribe to me if you get so many pages on here regularly for free.
What do you mean by get more freaky

? Like rougher? More over the top (with cum and such)?
have you given any thought about creating extra tiers of subscriptions where your subs can request custom renders with some of your characters? maybe start with 3-5 renders for the lowest tier and go all the way up to 20 or 30, as in a short comic. make it clear that they will need to provide majority of the details including the dialogues so you don't over burden yourself and struggle to create something that suits their unique tastes. obviously you'' need to limit such tiers based on your capacity. obviously you can't make these tiers cheap either.
Additionally have you given a thought to making this into a AVN. the adult games have been and still are a really good way to increase your income. and with the new AI tools you can even animate most of your renders without having to spend a ton of time or PC resources on them. i'm sure if you searched this forum for a bit you'll find most of the details on how to do them perfectly. i wasn't really a fan of those AI animations when they started to come out, but the most recent ones seem to be pretty amazing.
And before i forget, thanks for the amazing content. I'm a huge fan. unfortunately i don't (can't actually) sub to your page even though i'd like to. the only thing i'd suggest is, please extend the sex scenes and don't skip out on the transitional scenes, like changing positions. or stripping the clothes. the sex scenes are the biggest and most important part, so please stretch them out a bit more. you can even spread out the dialogues across even more pages, because some of them feel a bit crowded, just a few pages though. but yes, as far as possible please try your best not to make montage sex scenes like at the end of chapter 5 where they have sex all night long, but it's covered in just a few pages.
i highly recommend you basically just go through a phase 2-3 chapters at the very least where they are in like a honeymoon period. every time Dylan sees Isi he wants to take her. in different scenarios, like when she's cooking, doing chores at home, while she's working, more bathroom stuff. while she sleeps, visiting her at the office for some thrilling sexy time, in the dressing room of a shop, massage session sex (revisiting the spa maybe?), etc etc., sex in different outfits, and i don't mean cosplay, more like the naked apron, virgin killer sweater, and so on. most importantly the whole scene should be in the outfit, not strip naked halfway through them. The point of doing all these simple yet exciting scenes would be to make sure there's more than enough spicy content to the point where the subs will almost get tired off it, before moving to the next stage.
i've seen many creators struggle with creating newer and better scenes because they escalated things between the characters too fast and moved their relationship into the next stage too early. there isn't much you can do once you reach there. and if you think you'll just be milking your subs if you just add in so much filler content, then you are mistaken, because they are here specifically for the fappable content. atleast the vast majority are. they want to see more of isi and dylan doing it in different scenarios and places. as much as possible. it will never be enough. and if done right, the complaints will be minimal as well.
anal, bondage, pregnancy and those kind of things should be saved for later and again done over a substanial number if pages to do it true justice.
i've seen only the previews on where the story is at the moment, so i assume you still have the opportunity to do these things.
