In my opinion, if Aiden, Andre and Sofia leave the classroom, it really is closer to realism, but it is the demonstration in the classroom, behind the backs of the students, that makes this event more exciting for Sofia. Moreover, we mean that Aiden is trying to humiliate Sofia, for this she must bare herself in front of other boys, and not just in front of him and Andre. We also look forward to continuing.
Your version of the event is quite realistic as a one-time action, but it is not so provocative and humiliating for Sofia.
