Talk to Jennifer when she is naked in the kitchen, choose the "talk" option and ask about "something special".
My plan is to first make the storylines for each girl until the player has the option to have sex with them in different locations. After that, it will be possible to see the "normal" ending for each girl (my plans: Zoe, Mila + Zoe ?, Claire, Megan, Kelly, Charlotte and Amy).
After that, there will be optional storylines for the harem mode. Milfs will have their own route (it starts when mc decides that Mila needs a better social life and encourages her to start a book club that will include all mothers). The daughters will have another route (Megan, Kelly, Charlotte and Amy).
Zoe and Claire will be separated from the other girls, because in my opinion it would be kind of ridiculous to create an ending with absolutely all girls lol.
Thanks, I'll fix it.
