Hello Jashinn!
I played the demo, and it was a good experience, I plan to buy the game in the future.
Coming from what I know about game des and coding myself, I have a suggestion that would enhance the experience:
Adding a parameter for Vagina and Rectum "looseness" that you can view in the pause menu, of course this one isn't just for show, it have some mechanisms.
Firstly, she gain looseness when perform sex back to back in a short time frame, say, give 15s in between getting free and being grabbed into a next sex scene, outside of that time her looseness slowwwwwly go back to normal.
Secondly, her looseness add a percentage increase to the speed of osgarm meter (mastubate and sex scene), and also speed up the birthing egg progress (those normally take a whillleeee), it also increase the semen leaking visual that is already there.
Thats what I have to say for now, have a great day and good luck on the game.
