Seeing a lot of posts where people are struggling to make progress or are not understanding how the game flow works in general. So I'll be giving a general overview, some tips and conditions that need to be met for the scenes.
So, this might be either a version issue (based on the thread, I'm guessing this was made before 2.05 was released?) or a bad coding problem, but most of the stuff in this post related to the intimacy level is just flat-out not working for me. First off, the text says that the checkpoint for inserting is 60%, not 40%, and my play experience seems to support that. Also, I don't have the marks on the bar, which I've seen mentioned once or twice in the thread, so I'm having to eyeball everything. Secondly... nothing changes beyond that first checkpoint, except that I can do the perverted requests. If I wake her up by playing with her, even with a full intimacy bar, I still run away. If I stick it in, the dialogue is the exact same at 60%, 80%, and 100%. The only difference with the bath scene is I can masturbate, which I couldn't before.
Were there major (bad) changes to the game, or did something somehow get corrupted on my side?
