Furry porn VNs are canon in this Furry porn VN
Asterion is the only one we know to be famous enough that there would be porn claiming to be him, but seeing as he is literally the stuff of legends, it wouldn't look quite like the real thing. We have to consider that while furry porn is canon, doesn't mean Minotaur Hotel VN is. So it's not like the characters would be seeing the fan art we have done of them, nor the official art by Nanoff.
