No, I meant as a character moment for Sarah. Within the narrative, Stukov takes advantage of her—coerces her into sex as part of her training—which is rape. A common point in stories dealing with rape is how disempowering this is for the victim, especially with regards to their own sexuality; after the event, victims might try to display sexually open or dominant behaviour, either as a coping mechanism, or to reassess their “control” over their own sexuality. I just assumed that’s the kind of plot point that was intended, since you seemed to be framing Sarah’s sexual domination of Stukov as a form of revenge.
I actually have a slightly different view of the whole thing. And I don't think Stukov is taking advantage of Sarah. Let me try to explain this, whether he likes what is going on - he definitely does, but whether he would do it if he didn't have orders from above - I don't know. The point is that the point behind Stukov's actions is not to get straightforward entertainment for himself. That is more like a by-product, the main goal being the discovery of Sarah's potential. He uses his methods, walking a fine line where he understands Sarah perfectly and when to push and when to hold back.
I'm generally not a big fan of the whole "there was shouting, there was lack of consent. there was sex, so it was rape." pattern in games and fiction, It's just different, it's not the gruesome reality, and in our case it's even presented in a rather joyful way, because it actually signifies the discovery of new hidden possibilities in Sarah that don't do her any harm, that on the contrary will make her more powerful.
But this is too philosophical a point to discuss even IRL, with potential for hours and hours of heated debate. And we also have a language barrier, as I am not a native English speaker.
