Strangely enough, the first chapter is the only one that deviates from this general niceness, so don't give it too much thought if shit like rape does not turn you on.
And really, if you are going to fantasize about sex, why not do it in a consensual way? It's sad that so many people are so full of resentment that they would rather imagine themselves taking a woman by force than imagine a woman freely giving herself...
Anyhow, back to this hentai: one criticism I might make is that there are too many encounters and that they are a bit too casual and easy. As a result, they end up less meaningful and, more pertinently, less 'hot' since it's not like you are on the edge of your seat wondering what will happen next.
Most incredibly amazing part of this hentai:
The protagonist is a teacher in highschool and yet he doesn't get it on with any students!!! Yes, that's right: just like it's only a pathetic dickwad who, as an adult, is attracted to minors or acts on such feelings, the main guy is a 'nice guy' who generally doesn't do shit like that (for all that he is a total doofus).
This is hentai for decent men/women, it's not hentai for pedophiles or 'I wish I could' rapists! WOW
