The way she said it... even though it was a refusal, even though it was a direct contradiction to a suggestion bordering on a demand... the way she said it gave him little room to actually punish her. It was frustrating when her naturally sly nature wove her body through a thread of carefully constructed reactions, and the only thing he could do would be to act the cruel monster she (rightfully) thought of him as, or bend to her whims.
The latter, of course, was unacceptable.
He would have to call her out on her own game.
"Mm. How unfortunate." Then, slowly, as he stroked Fifi with one hand, he gently pushed the animal off of him with the other. "Well, if you cannot come to me..." He shifted, edged towards the end of the bed, then slid down onto the floor with all the grace of a panther, settling on his side in a lazily seductive manner; back pressed towards the overhanging comforters and sheets on the bed, fingers stretching forward far enough to stroke along Lust's cheek. He was surprisingly gentle.
"Then I will simply have to come to you."
Because, in the end, he knew this semblance of what they one had been would hurt her more than anything else.
