Who, do you wish to fuck? Who, is the cutest girl in school? What is the capital of Assyria?
Do you know basic trivia? Can you grasp the basic concept of searching for clues that are shining? Or do you want to watch a big breasted high schooler get turned into a fuck puppet for a horny old teacher? The choice, is yours.
Turns out, the NTR is quite avoidable here. So long as you don't mess up too many times, Asuna, the busty blond, can avoid pregnancy and think it was all just a dream. Literally you just answer the most basic of trivia questions, questions about things on the map, and sometimes answering questions that have no right or wrong answer. Truly, you really need to work to get this chick slobbering on her teacher's schlong.
All the sex scenes were based around hypnosis and corruption, in different forms, like one is sound hypnosis, one is aphrodisiac gas, another is seeing Asuna fall to pleasure and having her mind broken by the constant old man sex. The art is ok, not anything to really save on the PC, and there's basically zero reason to replay.
I myself got the "it was all a dream" ending, even though she lost all her virginities and was pumped full of old man jizz, she wakes back up in her classroom as though nothing happened. Pretty sure if she had checked her panties, they'd be full of semen leaking out of her ass. Nice of the teacher to give up on her and return her to the real world, but her boyfriend is going to be tossing a toothpick into a volcano with how hard sensei took his GF to pound town.
