Hear them roar.

"Oh, Joffrey," groaned his mother. Joffrey gave no reply but began to urgently fuck Cersei, his manhood moving in and out of her tight twat, giving it to her with his entire length. "Oh, Gods, oh, Gods!" she shrieked, pitching her own hips against his. "You're sooo hard!"

Joffrey gave a low shout. "Take it!" he cried. "Take it, you bitch! Take your son's cock!"

"Yes, yes," moaned Cersei. "Oh, yes! Make... make your mother cum, Joffrey! Make your dirty mother CUM! AAAAAAHHH!" Joffrey felt her walls spasm around him, and knew he would soon follow. He gave her a few more powerful thrusts, and then felt his climax starting. He began to pull out, only for Cersei to wrap her legs around his waist. "No, no," she murmured, "give it to me, give me your cum, give it to your mother, Joffrey..." He groaned and climaxed in her, filling his mother's womb with his seed. Then the pair lay together a moment, in silence.

Eventually, Cersei stroked her son's face. "Joffrey..." She stared at him for a moment, and then smiled. "I'm sorry. You are right--you are most certainly a man grown, and the King, and I have to respect that." She bit her lip, and looked at him pleadingly. "Still, I hope that you will always have some respect for your mother's advice?"

"Of course, Mother," said Joffrey, grasping one lush breast. "You... you're my mother. I love you more than anyone else."

"And you've certainly showed me that," said Cersei with a wicked smile. "An idea then. We go on to King's Landing and gather a new army there, for you to lead against your wicked uncles. It both allows you to shore up your power, and prove what... a rugged young man you are."

"It sounds perfect, Mother," answered Joffrey, kissing her. As the kiss ended, he remembered something. "Oh, that's right. I left the Stark sisters back in my tent with the idea that I would be back soon." He coughed. "I should probably go see to them."

Cersei frowned at this. "I see." She backed away from him and turned, giving her son an excellent view of her gorgeous haunches. "Well, if that is what you must do..."

Joffrey was left with the uneasy feeling that he had mispoke, somehow, and for the first time in his life had the feeling that he had to do something to make up for this. "Perhaps, Mother, you and I can... share custody of the sisters? It will make things easier..."

Cersei considered this. "Hmmmm." She turned to regard her son, that same wicked smile on her face. "That does sound like a good idea. Why don't you see to it, Your Grace?"

Joffrey gathered his clothes, got dressed, and left his mother's tent to go check his prisoners.
