Shadow

Shadow saw his stepmother's pregnancy as a problem. 

He saw that his father and his stepmother would doubt the new child more than him. 

He fought; he would lose out and lose their love. 

He wanted to find a way to cause his stepmother to lose the child. 

He set up a trap to make her fall down the stairs. 

The trap backfired upon him and caused him to fall down the stairs instead of her body.

At the bottom of the stairs, he broke his neck, and his soul left his body. 

As it travelled up towards the heavens, it got pulled towards his stepmother's body. 

He was poured inside her body. 

He run down stairs in her body feeling heavy, strange, and uncomfortable, to find his body had vanished. 

He he ran back upstairs to his bedroom and found it to be a nursery our decorated ready for the new baby. 

Nowhere in the house was a sign that he had ever existed. 

It was like the universe had a raced him for his actions and forced him to live a new through her.

Over the next couple of days, he found himself watching the world through her eyes, feeling her body as his own, feeling the baby growing inside of her as his own. 

He never knew pregnancy could be such an emotion, all magical and wonderful, and regretted his position of trying to get rid of the child. 

After that realisation, the strangest and most curious thing happened to him: he found himself in control of her body. 

Now he was his own stepmother, pregnant with his ownhalf-provincess married to his own father and making love to him every night.
