Hmm, how should one classify 'Sensei'? (1) "You're Despicable!" (2) "You Lucky Bastard!" (3) "WHY NOT BOTH?" Personally, I'm hoping that in due course he "takes responsibility, right?" And if he doesn't here's hoping a serious Yandere Switch gets flipped in Kotoko-chan.
Cakes, herbal tea, remote controlled vibrator bullet, pussy juices, Possible impregnation? DAMN! Now that is definitely a party.. Great art as well..Bravo Karakuchi!!
The way he teaches? Ah yes, the tried and true style of 'rewarding' your student for good grades, and lots of extra lessons.
Great ending though. I'd say that moreso than her 'getting over' the saving herself for marriage thing, and more that she loves him to the point that she considers him her future husband already, so what's the problem?
Heh...A reward like that only happens in soap operas, eh? You're forgetting one thing...Yeah, it happens in Hentai too, and you just so happen to be a Hentai Protagonist.
APPROVED!
