Nice update! I like that we already have a divergence based upon what path the MC is walking, as well as four different outcomes in chapter 7. I also like that we get cock in pussy directly in chapter 7, and no stupid "first we do a hand job, then we do a blowjob and possibly some cunnilingus and only when we've passed these bases can we proceed to actual fucking" (which might be apropriate if we're talking about an unsure virgin who needs to be cajoled/reasured into having sex, but otherwise no). A couple of suggestions (do with them what you will).
1. Right now, getting to the lust+chaos route is rather difficult, if you don't have access to the walkthrough. The reasons for this is as follows. Firstly, you have to balance between lust and chaos choices, which in of itself is more difficult than going balls to the wall in either direction. Secondly, as of yet, the balancing needs to be exact. There is only one exact set of choices that lead to lust+chaos (or at least this is my impression). Thirdly, some choices give different amounts of points depending on earlier choices, which is very difficult to anticipate as a player and might lead a player to give up on trying to achieve another route because he/she can't envision how outcomes could be different (without the walkthrough).
My suggestion here is that you create a stat screen that the player can view to see how many points of chaos and lust the MC has amassed so far. With that, the player can play around with choices to test different outcomes. Should you at some point add something like affinity or lust points for different LIs, that could also be presented in the stat screen.
2. In chapter 7, we get a greyed out choice if we're on the chaos or lust+chaos routes, which reveal that another route is possible. In chapter 6, we get two choices if we're on the chaos/lust+chaos route, but only one if we're on the lust route. However, the choice we can't make on the lust route is invissible rather than greyed out, which might lead players who are on the lust route to mistakenly believe that there are no other options in that encounter. My suggestion is to grey out that choice as well. That would be consistent and give the players a greater overview of the meaning of routes/earlier choices.
3. As of now, the chaos route gives one less sex scene than the other routes. If this continues (and to some extent, it's logical that someone focused on lust gets to fuck more), it will lead to the chaos route becoming suboptimal for players who want to maximize sex scenes (considering what kind of game this is, that's probably a majority of players). If that is your intention, some sort of "heads up" for the player might be a reasonable addition, so players who want to maximize sex scenes can adjust accordingly.
