Ear blushing feels like a whole new frontier of cute that we need to explore as soon as possible.
Great idea. The first move would be to do some historical research looking for any previously unnoticed ear-blushing pioneers--they've got to be out there.
And no ear-licking or ear-biting--that's all fine in its place (in some contexts arguably better, even classic), but much more likely to cross the Cute/Lewd event horizon. Which is also fine. In its place.
I'm getting confused between this series and another one that got uploaded around the same time, where a woman hires a person who wants to be a pastry chef someday I think. And the woman has an ex best friend that she became a pastry for in the first place, but now does it for this new employee. Oh yeah title was chocolate orange or something, and maybe I just found it recently.
