His Sucubus, Her Incubus

"Always do what you're told, no matter what."
Was Chan's motto embedded in her head as she looked at the mansion, gasping in awe of how big it was.
Suddenly, a man opened the door of the sleek black car she was in, holding it his elbow. As Chan held onto his hand, she felt sparks. But that wasn't right.
She was a sucubus and you didn't usually feel sparks unless.....
The man hissed, growling out "Mate" before slamming her against the pillar near the entrance of the house.

Chan was a sucubus and instead of taking souls of men and using their bodies for pregnancy, sucubi went around, selling their bodies. The world didnt have that many sucubi so when you saw one, keep them around.
Seth was an incubus and bought women instead of going around fucking the brains out of women. While they were asleep.
Incubi and sucubi traditions were different now.
They had a mating system, like werewolves. But they could not have mates with any other race. No humans or werewolves or anything like that.
What'll happen when Seth and Chan meet...
