Except Dean didn't exactly want to think it through, even if he was likely to get there eventually. He'd hardly had time to work through Lucifer's possession of him, but the further inclination of being his pet would only drag him down that much further.

Swallowing hard around the head, Dean squeezes his eyes shut, trying to keep up with his own pace without falling short. Especially now that Lucifer's coming in closer to the end, leaving him no room to falter. It's all he can do to keep going, lips having gone numb from fiction and tongue memorizing the path of Lucifer's cock. Dean merely does what he can, wishing he had his hand to work the rest but trying to fill in the gaps.
