To anyone reading this, if you want to go to the other route while she is squatting you need to select the dialogues related to peeing, what I did was taking her panties and using the vibrator with right click (it masturbates her faster), talking and spamming the right choices and making her cum 2 times with Rightclick vibrator then using the last finger option with right click and if you did it right she will pee instead of cumming.
I'm not entiretely sure but I think that all you need to do is talk to her once the first bar fills and select the first option, select "It is likely to leak pee?", make her cum 2 times with the Vibrator in fast mode (Right click), then with Finger 3 fast mode(Right click) make her cum, and once she pees select "It is likely to leak pee?" again and then select "I can't do that" and that will let you go to the other scene. It has worked for me three times
