The benefit, too, is that Lucifer will keep his word; he won't tap Istredd out again in this kind of scenario. Hopefully not at all, but he only made the one agreement.

Lucifer's said enough that no one can make him do anything, Istredd especially. Any bend and twist and break he makes to Istredd's hands are all by choice, liquid-movements giving in. He'll easily and languidly resettle, content.

"I picked the wrong person regardless when I let you into my head at all," he says, enjoying the feel of Istredd over top him. That should distance themselves from that first night, regardless to how far they've come, if only because their positions are flipped. "Even if you did know everything, you wouldn't be satisfied," he continues, amused. As though your thirst is ever quenchable.
