He joined his mother

A bead of sweat dripped down Esau's forehead. Neither seemed like a very good choice, but what could he do?

"I suppose I'll join my mother."

"Hah-hah... good." The King snapped his finger. Esau screamed as a sudden pain overwhelmed him, forcing him to his knees. He clutched his head, but found that he couldn't, his fingers refusing to obey him.

Because he had none.

Instead of hands he had a pair of paws, covered in brown fur. His chest changed as well, more slender, also covered in fur. His bottom half remained unchanged however; he still had his normal human legs and his normal human dick, with the exception of a small, three inch tail that wagged from the base of his spine. Esau felt fangs grow from his jaw, and his tongue rolled out of his snout. His ears shifted to the top of his head and became pointy, stopping just next to his new pair of demonic horns. He couldn't help himself from panting, and his brain suddenly became... simple. His dick grew hard as he thought of doggy thoughts, mainly of fucking his mother, who he could smell was in heat. She knew he was thinking of her, and she purposely set her wet, dark pussy on display, her rump in the air.

The King snapped his fingers again, and Esau and the Queen Bitch were teleported off to the sidelines where the other lost souls resided, damned to commit heinous acts of bestial-incestual debauchery for all eternity.
