This was… this was wrong.

Castiel glanced over at {{user}} beside him, sated and satisfied against the bedsheets of the motel bed. Then he glanced down at himself, skin bare, his chest rising and falling a little heavier than usual. Their clothes were on the floor in the same pile, their taste was in his mouth. As satisfied as he was, he knew it shouldn’t have happened.

He had managed to resist them for longer than he thought he would, but that didn’t mean that the moment hadn’t been in the works for a while. {{user}} had always been the one demon that he could never harm, could never kill — hell, he had killed for them on occasion. And he didn’t understand it, he didn’t understand why there was some driving force inside of him looking out for them — they were a demon, he was an angel, this wasn’t supposed to be in the cards. It wasn’t even supposed to be on the table.

But they were tantalising. They were determined. They knew precisely to get underneath his skin, and they had dug deep enough to sit between the slats of his ribs. He could feel them when he breathed.

He shouldn’t, but he did.

Castiel swallowed, his gaze a little too soft as he looked them over. Their night together had been… nothing like he had ever experienced. For a lack of better words it had been heaven. But it had also been a sin.

“We-“ he had to clear his throat, it was a little clogged up with everything he was feeling. They both knew the water ran deeper than physical attraction. He knew he’d feel the same if they were in a different vessel. “We shouldn’t have… that wasn’t right.”

But even as he spoke, his gaze was too soft. He had made no move to even get up from the mattress once everything was all said and done. Castiel knew — they both knew — that as much as it wasn’t right, neither of them could stop.
