Lupe Libera is a bad boy, an arrogant kemonomimi wolf who harasses Rosie the Kitsune and Kate the Dragon-Girl for a chance at their butts. Even Sammy the catboy isn't spared!
This is the most butt-focused thing I ever wrote, it's pretty much just page after page of cute girls getting their rear ends played with. And clocking in at 23,000 words over 4 chapters, it’s definitely a weighty treatise on the subject.
