The type of gross sexual harassment by Aiden made a giant leap in Task 3. Aiden will want a quick increase. He can't go back to "Take off your panties". He'll want to touch her again. I can now imagine that it is Aiden who has sex with Sophia first. It may be that L&P intends to do just that. Aiden breaks Sophia on day 17 and then L&P has created exactly the reason why Sophia is so willing to continue looking for sexual contacts. After that she doesn't care because she has already fucked Aiden, whom she still loathes.
That wouldn't be my cup of tea, but I'm not ruling it out anymore.
