What do you think about KingOfHell!Sam seducing and fucking Dean into submission? I think Dean would be freaked at first and try to fight Sam off, but Sam just feels so good on top of him that he would give in rather fast.
Oh, Dean would definitely be freaked! But I think King of Hell Sam knows how to manipulate his brother so well.
Right now I'm imagining a boyking!Sam crowned by the force of hell's corruption when he goes down to find Dean. Imagine he pulls Dean from the rack, but he doesn't want to go back. He killed Lilith; has followers and power. He wants dean to stay with him forever. So instead of painful torture, now Dean's being seduced by his brother.
And he resists--of course he does. This ISN'T really his Sammy. Except how he is. Except his voice; his eyes; his stupid hair; his clinging, too-big grip. Except how he still somehow has that brotherly smell that makes Dean think 'home'. Except how he says it's his job to take care of Dean too, even now.
And if his soothing words are spiked with poison; if his way of taking care involves holding Dean down with his powers and forcing unbearable, unspeakable pleasure on him? Making Dean scream more than he ever did for Alastair?? Well maybe Dean's a little okay with that, actually.
