Before the Pack Leader became the Pack leader his name was Packling as he was the first yet young of his group as he was ready for his task and was to infiltrate Equestria and start to breed with the local population of Ponyvill but little did he know he was about to have a new type of adventure that can grow the pack and make it into packs of each as it was his only choice but it was also the only choice on becoming leader of the packs as Packling was looking at the picture of Princess Celestia as she was going to be the first to be a host mother but instead it was Princess Twilight Sparkle that shall be the first host mother in Ponyvill.
Pack Leader: Fear not My child you will soon become Pack Leader and All will be yours my son.
Packling: thank you father I shall spread and create more Packs to each town behind every Pony's back without them knowing.
The Pack leader sends his son off as he changes and look's like a cult that suddenly allures female pony's but they all know he's going to princess twilights palace to introduce himself as he enters the castle and plans to wait for her to fall asleep to seed her in her sleep to carry the pack in her womb and to breed with other pony's as well giving a grin behind the guards as some of the guards were female and could not stop staring at the humble Packling in his illusion as he knew ho to get in private after breeding with Twilight.
Twilight: greetings new subject my name is Princess Twilight Sparkle.
Packling: greetings Princess my name is pack.
They both spoke for hours but suddenly Twilight felt weird in her body as she wanted Packling to follow her as he smiles and was ready to breed with her as he noticed a trail that twilight left behind as he smiles and was planning to look for other pony's as he smiles and noticed Twilight laying on her bed as he than starts to rub her back as he smiles as they enter the room.
Packling: you have a nice room hear.
Twilight: thank you packling though... speaking of witch I think I may have a wonderful thing for you.
She than shows her affection to lay on her bed as she smiles waiting for him as Packling was liking the Mare princess as he went up to her as he kissed her as they started to feel each other through the moon light as no magic can he felt as Primal changeling have pheromones that are strong enough to attract many females as he let it all out as female guards were all ready in heat along with twilight as he started breeding her as the moans can be heard echoing through the royal hallway's as the male guards were at their homes knowing it was the female guards on night shift as Twilight didn't knew something was wrong she let him in any way as he started to pleasure her as sweat fill the room and spike was sleeping in a different room keeping guard but was to lazy to get up as he finished he released his seed into her as he panted he could hear the mare slumbering after and he had head for the female guards as one by one they fall pregnant and in moments later the female population of pony vill was now bearing Primal changelings as his next move was towards the choice of Canterlot or Manehattan.
