Possession had just gotten a book in the mail that had spells that would end heat. She read through it but didn't understand the names of the spells and they had no descriptions. She felt her heat start up so she chose one randomly. When she cast it she felt something enter her vagina. She looked back and saw a portal had opened and she had no way of closing it. She saw the tentacle that was now halfway in her vagina. She succumbed to the pleasure and her mind went blank. The tentacle finally reached the cervix and started to push it apart. Her mind was being flooded with endorphins to where she didn't feel pain. Once the tentacle was inside her womb it started to widen. It then started to pump eggs into her womb. The eggs were a mix of changeling, griffon, and dragon eggs. The first two eggs were dragon. They were the size of a newborn foal. Her womb expanded. Next was a griffon egg. It was about the size of a grapefruit. Next was a changling egg the size of a grapefruit.
