With nervousness, and hesitation.

Arya scowled at the question, while Sansa **** on a pleasant little smile. "We... we tend to the King's... needs, Your Grace," she stated nervously. "As... as he requires it."

"Indeed," said Cersei with a significant nod. She glanced at her son. "And do you require it now, Your Grace?"

Joffrey smiled at this. "Oh, yes, Mother." He looked at the sisters, raising one blonde eyebrow. "Greatly."

The Stark sisters looked at him nervously. Queen Cersei regarded them coldly. "Well? You heard His Grace. He requires it."

Sansa and Arya stood there, frozen in shock. "What?" Arya muttered at last.

"You heard what I said," replied the Queen. "Do as your King requires." She gave a superior sneer. "You may rest assured that as his mother, it is nothing I have not seen before."

The sisters glanced at each other sheepishly, and then Sansa knelt before Joffrey and loosened his breeches.
