It's kind of hard to miss her meaning.

Eddard and Jaime began to roughly toy with the Queen's tits as she went back to sucking and jerking on their cocks. Eddard found himself once again marveling at Cersei's cocksucking skills, as the Queen's blonde head bobbed up and down, taking the whole of his hard length down her throat. Eddard gasped as her skilled tongue pleasured him, doing things to him that he had only heard about before now. And then suddenly, as he seemed on the brink of climax, she pulled off and went back to sucking off her brother.

Eddard felt a sudden rush of envy for Jaime Lannister, who'd gotten to enjoy Cersei's skills for so many years. Who can blame him for bedding that? Especially when the woman is so willing, and so able... He watched the Queen suck her brother, pale breasts proud on her chest, and his eyes went lower, to the still clothed portions of her body, where so much delight could be had. Shifting slightly, he gripped what reminded of that slight bit of lace and tore it free, revealing the silky long legs, the fine curves of her ass, and the tight wet pussy he'd come to know so well to view.

The Queen released Jaime's cock from her mouth to look back at him, with a faint smile, and then raised her haunches slightly. Eddard realized what she wanted... what he also wanted. Gripping his cock, he lined it with the dripping slit, then thrust forward. Soon he was buried in her velvety softness. Cersei gave great wordless gasps for a moment, then began once again to suck on Jaime. After a moment, Eddard and Jaime began to thrust into the Queen from both ends, Ned's thighs striking the pillowy cheeks of her ass, Jaime's cock coming in and out of her red lips. The room was dominated by their slaps, slurps and gasps.
