@RogerRoger Well for me, what I personally get out of this kink and how a SW reacts to being shrunk are heavily related. Her enjoyment/fear/consent/etc. all depend on what kind of scenario I’m in the mood for. Sometimes I want to feel comforted, so I like to imagine a gentle giant earning the trust of a suspicious and fearful tiny. Or I’ll want a more playful setup where the SW is bratty and defiant!
So I hope my response answers both of your questions. I’m sorry if I caused any confusion with the prompt. 
As for your example, I think something like a college professor/student scenario would be SO much fun. I love any situation where the power dynamic gets flipped. So imagining a college professor (typically older, highly-educated, responsible) shrunk by a student (younger, laid-back, maybe a bit irresponsible) is perfect. Why he shrank her is important too: did he just think she was hot? Did she piss him off by failing him? Either way, I feel like this would be a very degrading situation for her, as there is a complete change in power and status for the two of them! (This doesn’t reflect my own views- but this is how society tends to view things, and for role play purposes it can be fun!)
So I think she would be intimidated at first, and then maybe try to assert her authority over the student… which he quickly puts an end to, I would imagine. If I was writing this, I would make the teacher clever and always planning some sort of escape from the giant. Unfortunately for her, due to their size, the student completely dominates the situation. He can be as lazy and carefree as he wants, but she’s not getting away because he’s so much bigger and powerful. It would be very humiliating!
