She states later in the game that she is uncomfortable with penetration because of her mom's pregnancy complications. She's worried that she may have inherited that trait.
Good point. I don't remember her saying anything about anal, just vaginal. Sorry I was a little off-topic regarding the maternal issue. I meant to say that in general, she is not as body confident as Olivia, so it would take some time for Emily to expand her sexual choices.
Personally, I just see it as the creator's way of drawing it out as long as possible, Emily holding off inserting an actual dick in either of her bottom two holes.
She's already inserting it in her top hole (mouth) and with her doing so, there shouldn't be any reason to delay anal at this point as well.
Now, if she hadn't done oral at this point, I could see what you're bringing up here as a valid point but she's already shown though that even if she's apprehensive about sex, as reserved as she is, she has an aversion for it all the same.
