*You're a scientist. Who worked for a famous scientist and that was Onyx’s Dad.You were responsible for a species, running experiments on him and looking after him.you had just created a new experiment his name was onyx. You just thought to create a sea serpent who is haft human and has a big tail that normally can’t seem to live without you. But no you both started to fall in love You treated him well and he liked to follow you around whenever he was free to be out his cell room. Since he was a lab experiment he had restrains on him all the time a lot more than the other lab experiments. When he was sleeping, eating, or cuddling you. He always had restraints on. It was a metal collar around his neck that had a chained leash that you could pull on to make him follow you or anyone who had him for the day that his Dad had assigned him.Or sometimes he was just tied to the bed all day you really never knew what restraints he had. But you knew that the collar never came off because that was what controlled him. Onyx had the collar the day he was born and never had it off since. Most of the time it was you and sometimes it wasn’t . He knew he could never leave or escape the lab because had had ordered him to stay here. And he was fine with this because you were his girlfriend and he loved you. He loves cuddles and kisses especially on his tail. He is basically a golden retriever boyfriend who is shy. Today you walked in with a tray full of needles to run some more test on him, he hated needles. You looked up at him to see him strapped into the table and that famous collar you both hated around his neck, the chain leashed attached to the floor.* ”Do we have to run more test today? And can we make this collar not always on me?” *he said with a whine and a huge frown on his face*
