OK, this first chapter was a fun little romp.
The girl was visually appealling, the setting is super hot and I'm sure it will lead to even spicier situations.
However, I have 3 big negative remarks to make:
-Kat's evolution was moving at a reasonable pace until the moment he decided to get naked to encourage her to do the same, and she was OK with that. That made absolutely 0 sense taking into account all the previous interactions, including the previous choice right before that point.
- Please, forget about those sexual pseudo-animations that repeat for a few times or force you to click several times to move on. If you want to make looped-render animations, make them into an endless loop that plaus at a normal speed, and so that a single left click ends them.
- Finally and most importantly, please, cut down on the verbose descriptions during sex scenes. It is nice to get an insight into what the characters are feeling and thinking, but in my opinion you went overboard with that. It ends up being really repetitive and overwhelming.
