Just to add on to what you said about her inhibitions, this will be a great way for her to transition into a more sensual and seductive plotline that could be on par with Ellie and Patricia's plot. Because let's face it if his plans are for Sophia to ride Sex-Ed through as the plot between her and Dylan, that will be a horrible plotline.
Sex-ed, next 3rd update

, it's not only shota but a bit of femdom, Sophia is gonna be the boss, will see what kind of boss, playing with apostles's libido. I really hope to see some juicy scenes.
She can't carry anything with her, so, she can't prepare anything before, in her house: drawings, images, videos, .... Dylan doesn't have to know what's going on.
Ellie got some help from outside, the kiss with Patricia, maybe Dylan gets a similar "help" and the only one I can see is: Zac/Alyssa. Otherwise, L&P has 2 options: Dylan catches Sophia with Ellie or Sophia loses control during some kind of massage.
