Interesting information.
Although the painting scene is full of eroticism and Sophia felt quite relaxed and even good, it should be pointed out that it's all the teacher's contribution. Xavier was the one who convinced her and made Sophia believe that it was an artistic act, he created an atmosphere full of eroticism and easily chased away her fears. Of course he had an arrangement with Aiden.
Now, if we separate the artistic part created and suggested by Xavier from Aiden's contribution we see the reality. Aiden set the whole thing up to grope Sophia. And he didn't do that gracefully either.
no experience with women? or he's a natural born brute
Aiden's route has nothing romantic about it, it's domination with the use of force, more or less.
It just so happens that Aiden's task was combined with something artistic.
