Putting sexual assault in stories purely for shock and/or sexual-gratification sucks, putting them in stories as part of real character or necessary story development works but the focus of the content must absolutely not be about making the scene give anyone in its audience a hardon which this absolutely fails at. If you don't see how "Well acccchtually the sexy time is necessary for awakening their powers" I think you need to do some self-crit and ask yourself if the very worst of this industry has shifted your perception of what's ok and what's not.
