More debauchery, of course!

Joffrey's dreams were vague and filled with sex, to the point where it took a while to realize the sensations of a warm mouth on his cock were real. As he awoke, he saw that he was flanked by two pert pairs of breasts... the Stark sisters he realized gradually. That left him wondering who sucking his dick. A quick glance down revealed his mother, her lips stretched around his manhood. He gave a groan and began to thrust into her warm mouth. She groaned around his length, then pulled off and smiled at him.

"Does His Grace like his mother's mouth sucking his big, hard cock?" she said in a husky whisper.

Joffrey grabbed the back of her head, and rubbed her face against his throbbing length. "Swallow my dick, you dirty incestuous whore," he groaned. Cersei gave it one long lick and then gulped it down again. Joffrey turned and began to lick Sansa's breasts as his mother gave him a blowjob, then turned and gave Arya the same treatment. If this be sin, the Seven can keep their heaven, he thought to himself.

Cersei pulled her mouth off his cock, and groaned. "Oh, Joffrey, Joffrey, mommy needs you to fuck her!" She climbed up on the bed and turned around, showing him that lovely ass of hers. "Come on, darling. Stick that dick in me, and make me scream!" Joffrey rose with a moan and slid his cock inside her. "Mmmmm, yes, that's it, Your Grace, pound your mother's cunt, pound it!"

Joffrey grabbed her breasts and mauled them as he licked her ear. "You slut! You fucking, rutting slut! Fucking... nnngh... your own son!"

"Yes, yes, that's it," screamed Cersei. "Give it to your mother, make your mother scream!"

Arya and Sansa ran their hands over the pair. "That's it, Your Grace," whispered Sansa, "that's it, make your mother your whore!"

"Fuck her tight pussy with your big cock!" said Arya. Cersei stared at her, then pulled her in for a kiss. They made out urgently for a moment, then pulled away.

"Why don't you two horny girls see to each other?" hissed Cersei. Arya smiled and slid over to Sansa, kissing her. The pair made out for a while, then lowered themselves the mattress. Soon, the sisters were eating each other's pussies as Joffrey and his mother watched while continuing their own frantic coupling. The tent echoed with depraved, incestuous fornication, flesh slapping forbidden flesh as lewd taboo acts were joyously performed.

That was the scene when Lancel Lannister entered the tent. "Your Grace I bring...," he began, then saw the blasphemy going on. "By the Seven!" he cried, adding his own lesser blasphemy to it all.

A vague impulse to stop skittered in the back of Joffrey's mind, but was easily drowned out by the King's horny need for satisfaction and a vague sense of pride at the clear awe on his kinsman's face. Look at him, he's terrified, thought Joffrey. As he should be. He groped his mother's breasts once more. "That's it, mother!" he shouted. "Take your boy's cock! My royal cock!"

"Oh, yes, yes, YES!" howled Cersei. "Fuck Mommy! Fuck me! AAAAAAAHHHHH!" Joffrey felt her climax around his dick then came himself, sending another load of his seed deep into his mother's womb. The pair panted for while after that, then regarded Lancel.

"So," said the Queen Mother, grinning, "you have business with His Grace, Lancel?"
