Title of fic: The Sinner, His Saint & Their Angel
Author: @samanddean76

Pairing: Dean/Cas/Benny (Destiny) 💖
Summary: Benny's afterlife had been simple. Fight, kill, or run. But then fate had smiled upon him and delivered Dean Winchester, a living breathing human who would be his means of escape. But all good things come with a catch, and the perpetually dour fallen angel Castiel was the wrinkle that Benny couldn't shake. Not that Dean would let him.
But Dean and Castiel have their own tangled history they can't shake, and Benny finds that for once in any of his incarnations, he wants to help them, just as much as he wants to help himself.
Snippet: “Why not? Why didn’t you forgive him?” Benny pressed, his tone becoming harsh.
“It wasn’t my place or within my purview.” Castiel paused in washing Dean’s arm, trailed his fingers down and interlaced them with the Omega’s own. “I was a fool. One being used because I was the dutiful soldier, who wouldn’t question. I obeyed. And the Righteous Man needed to be broken in hell. He needed to take up instruments and torment others.” Castiel stopped, closed his eyes, and blew out a deep, shaking breath.
“I have made many mistakes in my existence. Some small, some big. But none had ever caused me to question. Until that day. And then it was too late. He was resurrected, and there was nothing that could be done to ease his suffering.” Castiel reached out with his hand, cupped Dean’s jaw, smiling softly when the Omega leaned into the gentle touch.
“I know we aren’t mated. He would never allow it. And too often I have been absent from his side as I hid in my shame. So please, do what is needed. Give him what he requires.” Castiel let go of Dean’s hand, placed the rag next to the bowl, and closed his eyes.
Benny knew what would come next. A flutter of wings followed by the absence of this world’s most earnest Angel of the Lord. But he found that he couldn’t allow it. Not like this.
“Please stay.” The gentle request was accompanied by Benny’s hand wrapping around Castiel’s forearm. “He’s going to need you. Even if he won’t say the words, he won’t be at ease unless you’re nearby.”
“And then what? Watch while you claim him?”
“It could be your penance.”
