Just to check it: I assumed this would come across, but I hate assuming. But are you fiddling with any of the positions or speeds in the rape scenes? For the way I recommended I didn't explicitly say it but I was just pressing penetrate, waiting about a second and a half, pressing slow, waiting that second again, then pressing cum. It's also possible that some coding inside the game is just wonky, and you just need to keep retrying. I eventually got it to work for me, but what I posted was just my best guess of what worked when it started giving me endings, I wasn't explicitly testing it as I tried random things to get it to work. The good news is that once you get your first special ending, you can get all of them. At least, that's how it worked for me.
