Submit yourself to the ancient Inca demon
From Create Your Own Story
"All right," you say. "I submit myself to you."
The demon smirks. "Excellent. Now hand over that pendant."
You relinquish the pendant and the ancient Inca warrior drops it down the hole to land on the corpses. He then raises his hands, enveloping you in a demonic red glow. When it dissipates, you find that all your free will is gone. Your soul is his.
The demon strips nude, motioning for you to do the same. He picks you up, places you on the altar, and mounts you, fucking you hard with a huge cock that causes you a lot of pain. Soon he shoots a huge load of semen into you. He grunts as he pulls out.
"Congratulations," he says. "You are now pregnant with the Demon Messiah. He will be a being with all the powers of a demon overlord, and the human DNA you have provided will make him immune to all forms of anti-demonic magic. He will be unstoppable. He will conquer the world and exterminate humanity."
You tremble in horror at what you have just done. The demon motions for his skeleton servants to take you below. "Do not abuse her. Her guilt will be torture enough. She will have to live with that for her last nine months of life."
