It's difficult to imagine the task without having an idea of the future path of the tasks.
I'll try a different path other than the one of exposing and embarrassing Sophia. Let's overthink out of the box
Let's start from the ride. The ride won't be short, you don't bother to buy a suit etc to drive to the other side of the city or something close, where they could have already met with their own car/bike. So it must a place outside the city. I'd say a ~ 30min ride at least. The whole event takes place around noon and Sophia has to come back at least for the Dylan event or to bring back Emma. So let's say a ballpark of 30+30+30 minutes between commuting and the event itself. It's doable.
Now, why going out of the city? One possibility is the beach, the skimpy bikini etc bla bla bla, tried and true, boring.
So what if, instead, the whole point of going outside the city is to bring Sophia outside her comfort zone and in a place where she can also be "free". She won't be the mother, the wife or the teacher, she will be just a woman. Nobody knows her, nobody can recognize her. A place where she can start a sort of double life. Something else than a caring mother, a devote wife and a dedicated teacher. A place where she can free her frustrations and desires.
Ok, I know, everybody will start proposing she will join a high class brothel, she will be a high class escort,
Apollodore will even cite "Belle de Jour"
Yes, why not, after all L&P said "...will she fall into all the temptations and become a filthy wh**e " in the description. He could mean it literally after all. But it could be something less obvious that we can try to imagine, frankly I'm not a fan of the wh**e thing too.
In any case what I mean is that the tasks could slowly go to a different direction, taking Sophia to this double life away from St Alejo, obviously incrementally and in the spirit of the game. So this task, the 3rd, could go in that direction. As proposed multiple times it could be something along the line of the bikers bar, but without nudity, glory holes etc. Maybe some groping, maybe the stage thing, a sort of "open pole" event in which Sophia has to take the stage to dance and collect the tips (hence a more covered cleavage to avoid the tips falling off...
). That's just an example, the task can also be something in which Sophia is not the "main character", something that stimulates Sophia's sexual curiosity, maybe she will be the voyeuse this time.
I know that this double life scenario goes in a different direction, and it may have even a darker connotation than the simple extortion/voyeurism thing. But a speculation is a speculation
