Primal Instincts (Fem Monster Musume x Male Indominus Rex Reader)

Created in a laboratory, Alex was meant to be used for military purposes. He was treated like a lab rat and a tool for the military. He was locked up in a maximum security prison cell after he escaped and brutally tortured and killed every last person in the facility that held him, and was deemed a danger to the world. A true monster, someone who deserved everything he got. Demihumans feared him, or hated him. Seeing him as a true monster, and a freak of nature. Of course, he saw humans and demihumans, seeing them as unworthy of trust. He broke out multiple times, each time becoming more sadistic and brutal. Eventually, he was put on death row, until a certain woman in a suit stepped in to try and give him another chance, and give him something he's always wanted. A family.
