Is it just me or is this manga getting slightly more horny?
It kinda feels like an editor has been nagging the author to include more sexy stuff to boost ratings.
You say that as if the book didn't start with a young girl getting turned on by her dog. (At least until she started seeing him as part of her family.)
One of these days someone is going to accidentally fuck a dog
...accidentally... I'm sure.
But nothing happens in a story like this that the writer doesn't want to have happen. If in the next issue not a single persona had even the slightest horny thought in their head, it would be strange, but you'd still have to accept it as the world narrative. If no one questions the giant super model with inhuman proportions that appeared the same day a bunch of dogs become attractive humans, then that's simply how the rest of the world views the situation.
I could see far more people trying to pretend their dog is a regular human than people pretending to be a dog-turned-human simply because it's a easier and funnier story to tell... unless maybe there was some sort of "trying to hide from the Yakuza" sub plot going on.
