i still can't fuck chloe i'm done with felix man and also i can't have sex with him mom only his dad and i haven't met dad's coworker scene what should i do
Well, when you say that you are done with Felix, do you mean you chose the Felix path? When you make the choice early on with Chloe for who to use the liquid on, you can't go down the other storylines just yet; so if you chose to help her feminize Felix, you can't have a relationship with Chloe (this is being added, but it's not currently available).
So if you chose to go with Felix, you won't get to have sex with Chloe.
Also the Morin parents depends on your femininity, so if you are playing a feminine character you will have interactions with the dad, masculine characters have interaction with the mom.
As for the coworker scene, have you started doing anything with your mom? It starts with 5% femininity or higher. You can try checking with your mom or dad and see if they have a story options for you. There is one point where you have to confront your father while he is in the living room so you might check for that, as well.
Yes, Vice Coordinator is the final promotion for that job line.
No, currently you cannot have sex with both Felix and Chloe.
Uuuuh, if you've already maxed out relation with the parents, it should've definitely happened, it's a very early scene. Its during the early parts where your mother is having you try on clothes before you actually start building relation with them. So, you may have missed it, it is pretty brief, but it may be bugged. I did rework that beginning part of their relation content, so it's possible I messed something up, I will take a look at it.
