Most assuredly.

As Joffrey prepared to plunge his cock into Sansa's depths, his mother quickly knelt before him. "Wait, Your Grace," Cersei murmured, quickly engulfing his member in her mouth. Joffrey moaned as his mother lathed it with her tongue, licking up the remnants of Arya's juices, and then watched as Cersei turned and licked Sansa's wet cunt. Sansa gave a little moan at that, then grunted as Cersei moved away and guided his cock into her.

"Mmm, yes, take it, you little bitch," muttered his mother, as she watched his dick slip inside. Soon his hips were slapping noisily into Sansa's shapely rear as they fucked with greater and greater urgency. Arya had stirred, and was licking her sister's breasts, while his mother leaned back and smiled at the debauchery.

"OOOOH!" Sansa cried. "Ohhh! Your... Oh, fuck me, FUCKKKK!" Joffrey felt her cum, and then pulled his cock out of her.

"All right, you whores," he said with a sneer. "Come here and take the royal jism." His mother slid before him eagerly, while Arya and Sansa adjusted themselves so they flanked her. Joffrey began to stroke himself off, while pausing to slap his sluts' faces with his hard dick. "What are you bitches?" he asked.

"Your filthy whores," said his mother with relish. "Come on, Your Grace," she continued hefting up her breasts, "cover us with your seed!"

"Make us dirty!" said Sansa eagerly.

"Do it, you motherfucker!" shouted Arya. "Cum on us! Cum on your fucking degenerate sluts!"

Joffrey grunted and then his climax began to spew out. He shifted his cock, so that each of the three women was covered with his juices. As he finished the three began to lick it off of each other, caressing the full curves of their lovers. Joffrey leaned back and watched them, feeling oddly sated.

Cersei quickly embraced him. "I hope Your Grace found all that... educational," she noted.

"Oh, very," said Joffrey, as his eyes closed and he found himself drifting off. He felt Sansa and Arya lying on him as well, and thought, as went to sleep, that being a king was really quite pleasant, in all sort of unexpected ways...
