Experiment 360

Y/n has been tested and held captive in a lab for 4 years, she's what the doctors call a "complete hybrid", she's different from the others that sprout tails and ears. She finally escapes but is being hunted down by the same people who created her. What happens when the very person that experimented on y/n takes an odd an obsessive interest in her? What happens when she finds an odd hiding spot, as a young mans pet? *This story contains cursing, violence(a lot), and maybe a little tiny bit of smut*
