The nix loved when you came around. Sebastian loved hanging around you and helping you swim around his lake.
You stood in the shallow end of the lake as he swam up to you under the surface of the water to surprise you, but a new smell overcame him, a new, delicious blood. From your stomach. Swimming up to you under the water.
Taking in the new smell of red from you. He's already made the connection that you had a tiny creature in your stomach with a dialectical blood coursing through its unborn body.
He could get drunk off of this. Sebastian's hands go to your baby bump and gently touched it. You jump at the sudden feeling of the hands because you didn't know the nix was there. His iridescent merman-like tail twitched around behind him before his head popped up from the surface. "When will the baby arrive?" He implores. His tail lifts up, the light bouncing off the scales creating a beautiful reflection.
