>>113248278It's from artist "bbulala". Although, I should advise a lot of his art revolves around very strange pairings and lots of fetishistic art, which I'm sure theses are his appeal, in case you are curious to see his FA account (which the site, in turn, is currently down).
Hope this helps, buddy, and if you wish, I can recommend a few more artists who like Rotor that are more adequate and balanced for your taste.
