A/N: Random drabble. T for non-graphic sex. I love me some incest~
"Cersei, sweet sister, tell me you are mine," Jaime growled into her ear as he struggled to maintain his brutal pace. "Tell me!"
"Yours- I'm yours," she gasped, turning her face into her pillow in an effort to muffle her cries. But they would not be stopped, and she sobbed her love for Jaime out through hot mouthfuls of damp fabric.
"Cersei," Jaime groaned, for no other name ever would come to his lips, "Cersei, my Cersei..." and he cried out his release, the blunt nails of his fingers digging into his sister's thighs as he came.
Cersei could say nothing through her harsh panting, but reached behind her to seize his wrist roughly as she pushed hard back against her brother a final time.
She collapsed forward and lay face-down for a few moments, and Jaime watched back rise and fall with her breath as he knelt behind her, still connected intimately.
"I love you," he said suddenly, and it sounded for once more like a promise than a confession.
"I know." Cersei had never been as good with her feelings as Jaime was with his. "I... I know."
Jaime brushed some of the long gold locks of her hair aside and bent down to reverently kiss the nape of her neck. His hand covered hers. Their fingers intertwined.
"Will you ever say it to me again, sister?"
"One day," Cersei whispered, and it sounded for once more like a promise than a placation. "One day."
