The Queen Mother shall.

Suddenly, Cersei pitched back and began to scream. "Ohhh, ooooh, YES! GODS, YES! That's it, Joffrey! Fuck me! FUCK ME HARD! I'm CUMMING! AHHHHHHHH!" Joffrey felt her spasm around his cock, and gave her ass another swat.

"That's it, you horny bitch!" shouted Joffrey. "Cum on your son's cock!"

"Oooooh, yes," cooed Cersei, as she slumped forwards. "Sooo good." Arya and Sansa stared at the older woman in naked lust. The Queen glanced at Arya, then spread the Stark girl's thighs open, while pulling herself free of her son's hard dick. "Your Grace, why don't you pound this little Northern slut now?" hissed the queen.

Joffrey chuckled and began to rub his dickhead against Arya's wet cuntlips. As Arya gave out a moan, Sansa whimpered. "I thought...," she began pleadingly. Joffrey couldn't help but smile at that--he'd reduced these Northern bitches into a pair of horny sluts, begging for his cock. It actually made him wonder which one to fuck first.
