I'm gonna take a further look at this, but I found the "Sex simulation" aspect to really slow down the experience. I've never been fond of the turn-based sex system games like Throne of Lilith used as I find it makes situations feels extremely similar, and there's only so many ways to say "you thrust fast". For what it's worth, it seems you gave a decent number of dialogue/word variations. Definitely prefer just reading through a sexual encounter. Not quite sure if there IS a grander story that gets revealed through different encounters as I did not get too far into the demo, nor how long the demo is.
I won't lie, I am more into the medieval period for the fantasy elements, which this game does not have beyond the existence of potions. I'm kinda more into monster girls and girl monsters. I do not think that should be a takeaway from the dev/writer, as I imagine there are many people that enjoy it just being a normal experience. Still, it does detract from my own personal experience, so I might as well mention it.
If there were one feature I would suggest, it would be a way to increase the text speed.
