I want to share an idea, if that's okay.
On the balanced or dominant route Laura could give her boyfriend a "gift." After how much fun she has had in the last few weeks, she decides to prepare a threesome for him. Because she loves him and believes he deserves it. But since she is not comfortable with the idea of her boyfriend sleeping with other girls, she decides to ask a person she trusts a lot...Ashley.
I don't know if it would be technically possible (if the AI would be able to), but the image of the mc looking down and seeing the girls playing with his cock I think it would be possible. Or one of them taking photos while the other fucks the mc. I repeat, I have no idea about it, but it would be a plot that I would love to see and would not clash with the main story. I know that the main character is Laura, and surely what most people on this forum want is for her to have more and more sex and with more men. But personally, the chapter I liked the most was number 20 (I think), in which she tells us that she has spent too much time with Nathan and she doesn't want that to get in the way of their relationship. I fucking loved that episode (sorry, I'm not really into the submissive route).
Anyway, congratulations on your work, I think you have created a visual novel that stirs some feelings inside my head. A month ago I showed your vn to my girlfriend and she is hooked on the story. Many thanks for everything.
