Can't... resist...

Alexia's mind was already blank from the multiple orgasms. Even though a small fragment of her mind remained sane, it could do nothing to break her out of the King's immense strength. The tentacles stopped thrusting and reached into her as far as they could, and started releasing huge spurts of thick cum. An additional tentacle **** its way into her mouth and down her throat, depositing the same substance directly into her stomach. Half-**** from the ****, she could only let the King pump her full of the demonic seed, until they overflowed from her orifices. Finally, the tentacles loosened and left her on the floor, lying in a pool of semen.

Alexia began convulsing. In pain or pleasure, she couldn't tell anymore. Her skin color began to change, turning into a blue-ish hue. A pair of horns popped out of the top of her head, and a small tail grew spontaneously from her rear.

"Very good. Very good! I think you will be my new favourite, princess..."

"Princess Alexia," replied a sultry voice. Alexia, now standing, strutted to the King's side. Her hips swayed seductively with every step. She was now a succubus, a loyal servant of the King of Darkness, and would become one of the most feared demoness in the world.

THE END.
