An Audience With the Devil.

You found yourself once more standing before Master Satan, he smiled at you as he gestured for you to approach. You moved before him, bowing before your Master.

"Rise, my child," Satan said, and you obeyed, standing up as he admired you. "You have done well, you have earned a great reward."

He placed his hand on the head of the Incubus that was sucking his cock and pulled him off, sending him away. Satan's cock was bigger than any mortal or Incubus you had seen before as it throbbed with anticipation. You grinned as your tail swished behind you.

"Come, mount me, take your reward," Satan laughed. "You have earned it!"

You smiled and mounted him, letting out a scream of pleasure as you pushed down on his cock, feeling its massive girth filling your pussy. You moaned as you bounced up and down on his cock, feeling his power flowing through you as your massive tits bounced. Despite its size, your body was accomadating to it, another advantage to being a Succubus.

"What do you want, slut?" He growled.

"To fuck me!" You screamed in pleasure as the massive cock slammed into you. "I want you to cum inside me Master!"

"And what are you?"

"I'M YOUR HORNY HELL SLUT!" You screamed as you felt the cock penetrate you even deeper, taking in as much as it as you could. "ITS ALL I"LL EVER BE! ITS ALL I WANT TO BE!"

Satan roared as he thrust his cock into you, nearly splitting you in half as his cum filled your body. You screamed as your body expanded, you now stood nearly 10 feet tall and your breasts and ass were expanded to proportions the likes of which mortal porn stars could only dream of. You came as hard as you could, your juices coating your master's cock as you felt your wings grow larger and your tail split into three.

"Fuck... thank you master..." You moaned as you woke up, finding yourself with your fellow demons. You smiled as they were admiring your new form.

You were no longer a simple Succubus, now you were a Succubus Queen. You felt the power coming from you, absorbed from the mortals across the city and the former Angel.

You were now the most powerful demon in the city.
