Overall, been a very nice update, adding a lot of new content/options.
Some general thoughts on gameplay/balance:
1) I like the addition of being able to talk to the girls and mothers out in the world, with the option to increase corruption, naturism, and fear. It would be nice if this was also a possibility during home visits, applying to the same 2 max limit, of course.
Ideally, the "talk" option for mothers would be its own subheading during these home visits, and also include the misunderstandings, fair-use law, and "what your daughter told you" options within it (and therefore "talk" rather than "small talk"). This would reduce the number of listed options, which would mean that the "time to go" option would no longer require scrolling down to access.
2) I wouldn't mind having an "affection" raising option added to small talk as well. Say a general conversation option that raises affection by 1 and caps at 35 affection.
3) Home visits to the girls get a bit OP. Would suggest a bit stronger diminishing returns on the "train attribute" option. Say a max stat change of 4 once you cross the 50 threshold, if not even a bit more severe than that. By that point, you can get the girls to do all sorts of favors during the home visit anyway. The cap could, of course, be something we can set in options, so players can adjust it up or down, depending on how effective they want "train attribute" to be.
4) Potentially add a "grades" option to "train attribute", basically a tutoring session that would provide a 1 point boost to grades and, say, half or a quarter of the int gain a girl would get from training int. And it should take probably an hour, time wise.
5) Being able to call up sponsors daily asking for extra work seems a bit off, balance-wise. Not only is it seven extra commissions per week per sponsor, but you get to pick the exact type you want. All the extra work also means you unlock more sponsors faster, so perhaps it shouldn't count toward the overall sponsor XP? It should probably have a use limit per week, 1-2 max. Also, it should probably be limited to what you've unlocked rules-wise. Like if I haven't unlocked the ability to use students and/or mothers as escorts, I shouldn't have the option to use them that way when requesting extra work. The various companies' lawyers wouldn't like me doing that, I expect.
I might even go as far as to say that it should be removed entirely, and instead, that when you do the "financial issues" option, that is how you get an extra gig from the company, with its cost in reputation.
As is, I think the extra work option is so powerful that, from a power gaming standpoint, you pretty much have to do it. And it is also a bunch of extra button presses for the player, with a few minor annoyances to it as well.
Edit: even more broken than I thought. You can pick this option 1x each time you call them, so there isn't even a 1x per day per sponsor limit, but rather, you can get up to 4 per hour extra.
6) There seems to be something a bit off with how quickly grades raise as well, once you get past a certain point. If I have new girls, and I give them hints, it'll take about 3-4 days for the three new girls to hit their first week's grade target, with them doing advanced physics homework. All well and good. But once I get them to that point, I swap them over to photography lessons, and shift my actions away from hints, and into clothing removal and some sexual stuff. Yet at this point, the girls will sometimes earn 20+ grades in a single class session. This is all with a teaching assistant helping.
Issue to maybe address:
I have a girl, Nancy Lace, who has home visit events that start prior to 15:00. When I look at who to call at 14:57, it'll show the ! marker that she has an event available. However, travel time means I arrive after 15:00, and therefore it isn't. Obviously something I can work around by going to her place earlier, and I can see the cut-off time in the student overview (but not on the call screen by hovering over the !), but it does create a situation where a player can go visit her because of the !, but then not get the event.
