I don't know what's sweeter: the glasses girl (glasses girls are great!) finally getting some love from her beloved sensei or the happy frog couple....
Well, I am 100% interested in this sweet Vanilla release, I'll tell ya that.
I have to say though I found his inner fight between reason and instinct rather interesting, the way it was shown.
Really, there was just no way reason could have won.
Great ending though. When a guy takes your love juices in tubes in order to study them and find out more about you, I think it's safe to say he really...loves you.
One might wonder if 'Goroumaru' and her 'husbando' were watching Sensei and Himari (ahem) "doing this and that" in similar manner as a human couple might watch an adult movie on their honeymoon to (ahem, again) "get into the mood".
Also, personally hope Himari is older than she might look, else this may cross into 'loli' territory.
Climaxing ten times? Good thing it doesn't actually make one go blind, otherwise it might be said of Sensei ... "He Blinded Her (Himari) with SCIENCE! (that is. the Science of Human Female Biology)."
