No incest mode, but also did cheat instead of cheatrelated as I am not into contact with related people personally.
then you didnt follow my walkthrough because mine says
"Type in “cheatrelated” instead of mother’s friend"
that said though not a common mistake based on what people post here I did make the exact same mistake as you in thinking that incest only applies to the main character, it does not. The incest cheat is for the whole game not just you so without using the related cheat any scenes with Linda and Jake/Jane, Karen and Kayla, Emma and Brittany, Suzie and Naomi and more will all be gone this actually even includes a threesome you could have had with Emma and Roberta (which I still cant understand why that would be considered incest). So if your like me and dont want Emma and Brittany to be related to you, then you have to choose between pretending that your adopted (use related cheat) or missing out on a lot of content (dont use related cheat) ... I dont know about you but im adopted because there is no way im missing out on a potential threesomes between Abby and Lydia, Jessica and Julie, Katey and Amy, Lydia and her Mom or Rio and her Mom (Asa Akira is awesome please more of her content)
