i just took what i remembered from it, haven't played it in a while, so i didn't remember that Tiff had given blowjob and received oral sex... about Aliza, i do know that she had sex in bad endings, but i was just considering the scenes with the MC, otherwise, we could consider that all of them had sex, due to chapter 8 or 9 bad ending, where Hunter fucks all of them, when the MC is both blind and deaf...
i never said that 10 would be the last one, as i said i don't know the dev plans on how many more chapters he is willing to make, just that IF he does finishes the game in chapter 10, it would be nice to have sex with the remaining 5 girls
