Savage Isabelle

Ever since humans took over their world, most of the animal folk have already been enslaved for humanity's convenience and pleasure. Isabelle used to be the sweetest and nicest dog you could meet; now she has been fucked over so many times that her mind was broken, and rebuilt with lots of drugs that alter her mind and body so she's a sex-crazy maniac that only thinks in fucking, she was also injected with steroids so she would be so big and strong that no animal would be able to escape her when she's commanded to rape them, and she was given just the right tool for the job, a big hard cock that she'll penetrate all their holes savagely until they submit, she was turned into a living torture device to punish those animals that still try to rebel.
