Sounds fuckin horrible yo! I hope l&p never add such a scene!
There have already been numerous masterbation scenes. None of which were in public yet.
Here is how it ends.

So it's already established that "Waiting in the car for Dylan" is next scene. What is she going to do in the car alone? Maybe something random and lame like get a phone call. However the fact that she was "day17_Sophia_was_turned_on_by_the_guys_filthy_thoughts" only moments before indicates she is in a horny state.. This is her thoughts: "Sophia, who hasn't been laid in weeks, suddenly felt how she got a little wet from these lewd thoughts."
Other time she had lewd thoughts like this what did she do? She was watching porn in the living room and chose to masturbate.
What is the next logical step from masturbating at home? In public in the car where she thinks she has some privacy. It all adds up. There will be SOMETHING that happens in the car... I think most likely masturbation as that is what all this foreshadowing has been building up to.
There are 2 other possible events that can happen in the car waiting scene assuming it's an actual scene and not just a short segway between the mall and the bikini fashion show.
1) Random Phone call... There are lots of those that happen. A random phone call would be a way to keep it from getting erotic. Who knows who is on the phone probably to setup some shit for a day or 2 from now in game which is many months real time.
2) Highly unlikely, but those 2 thugs that almost raped her the one day could show up again at this very moment. The moment they return should be a surprise. Now would very much be a surprise. They are overdue for a return.
