Rin and Hane from the anime Bakuon! They're getting their asses fucked. 'nuff said.
Yeah, so if you don't know, Bakuon! is about girls who like motorcycles, and each girl represents a manufacturer. There are these promotional type pics of the girls posing in tight show girl outfits in front of their preferred motorcycles. Not something they actually wear in the show. I figured, I've probably never drawn shiny cute show girls getting it in the ass before, and I liked those outfits.
Now I have.
Maybe I'll draw some of the other girls from the show too, later. Who knows.
Anyways, this is a less intense, rough-but-could-be-consensual version.
Here's the usual Harmonist11 style version, more non-consensual, extra fluids:

And here's the totally Harmonist11 style version, with the girls also blurting disapprovals of their situation:
