I'm decently sure Piemations does porn. I've come across the porn blog multiple times and it looks almost exactly like his art style. Oh, it's also horse porn.
i was like “so what” until the last part
i used to follow a guy who drew weird porn and then would also casually draw horses in sexual positions but i followed because the 10% of stuff that was good was good and then someone sent him an ask asking him to draw centaur porn and then he said “once you’ve done the real thing why would you draw only half of it” or something and then i unfollowed
