Very well done. Good Writing, very nice attitude of the women. Thank you for creating this. I'd love to see more of that. Here some wishes and suggestions.
1) I hope that you can keep up an interesting story. Maybe some kind of battle and plotting between the sisters or something else, that keeps you curious.
2) Maybe even a little more diversity of the motivations behind the woman. It may be a bit too boring in the long term, if each and every woman is getting wet like shit when men suffer. Maybe there is room for a small amount of variety regarding why they like to dominate men or what turns them on. Of course, not too much variety, It is just meant do give each woman a distinguishable character. Otherwise it is like 4 times the same woman with a different model. But I believe, you already have something like that in mind.
3) Hopefully you don't over do it with all the decision possible. A lot of decisions mean a lot of work. Especially if you have sub/neutral/dom paired with evil/good and so on. So far it is handled pretty well, but it may become costly and complex. Since I really like your style, I have great confidence that everything you prepare as story will be quite good. I want to see your story and not create my own.
4) Don't listen djkunn ;-) For me it makes no sense to allow the MC to avoid a lot of stuff. It prefer that the MC is the main subject of femdom play.
Also I do not care that much about other males. They may be useful to demonstrate the power of the woman, but I don't need their story. I only identify myself with the MC and like to be focus of the interaction with the women.
5) Normally I prefer less intense starts, like MC living normal live and slowly falling in some kind of trap. That is of course already handled differently here. Still, I hope that after that kick start, there will be a calm and and slow escalation. Before we get to the extreme stuff
6) I like the way the MC is thinking about his situation, already feeling for some kind of plot behind the scenes. I really hope you can continue with an interesting MC. I'd love to see the MC plotting stuff and trying to find a way out of his situation and finally still be beaten by those women. That intensifies the destruction and makes the woman feel stronger. At least I see woman more dominant and godly, if they can think ahead and dominate with there intellect instead of only beating shit out of the MC. That may be an opportunity for the already mentioned variety of the woman. Some may preferring physical humiliation, other may have other ways to do so.
I'm really looking forward to everything you have up in your sleeves. As I said ones, I like your comments in this forum and hence expect that in the end things will most likely escalate interestingly in the end.
I've never wrote anything that long here before, but the game deserves this.
And very selfish wish: Hopefully we'll see some forced femdom urination plays in the future.
and edit: Don't change stuff because someone like me asks for something. Build the game you want. The good start just made me dreaming a bit about the perfect game for me personally. But that is the one I have to create and not you
