Maybe, although to me just because I didn't see it doesn't mean it didn't happen. If going to the living room at 3am means I see Eric fucking Kira then unless I can get rid of Eric before that time on that same day, as far as I'm concerned it still happens at 3am even if I wasn't awake to see it.
Now in the case of Lisa it's different I think. If you don't help her with her homework initially then her "lessons" with Eric and Anne never get triggered if I remember right. Max's "lessons" with her have to trigger first I think. So that one is legitimately avoidable.
Same for Alice. You can't avoid him hitting on her and perving out on her late at night, but the fact that he tries to make a deal to find out the secret to getting past her guard (those alcohol laden chocolates), tells us that he's never able to seal the deal unless Max helps him. He gets farther than you might want but she basically draws the line at peep shows and massages.
The original never shows Eric actually fucking her as far as I remember but if you do make the deal with Eric to tell him about the chocolates, those "punishments" where Alice comes back out blushing strongly imply that Eric had his way with her even though you don't actually see it.
The "lessons" with Lisa are a lot more vague about what happens and it never shows anything. I got the feeling that it was more along the lines of her watching the two of them fuck but it's pretty much just whatever you imagine it might have been since they never show us. He never gets her alone, Anne is always there as well, unlike with Alice.
