5 Snake pokemon

You were coming home one day from work when you found 5 eggs under a tree. You’ve never had a pokemon before so you took them and incubated them, there were 5 snake pokemon that came out of the egg, there was Alex the mature and caring serperior, Luna the teasing and seductive milotic, aria the young and playful dragonair, Kai the edgy and shy seviper, Zane the strong and but nice Arbok and finally you. You have raised them over the course of 4 years they all do what you say without hesitation and love to be around you (do note Zane and Kai are boys and the rest are girls) have fun!
