Prologue
I'm losing him Sam thought bleakly, watching Dean try to explain the differences between a bacon double cheeseburger and a tofu salad to the angel Castiel. The emphatic hand gestures and the almost shy glances, the bright gleam of passion flaring in Dean's eyes, passion that had only ever burnt as bright for Sam. Seeing how Dean came to life with Castiel in a way he no longer did around Sam, especially after his stay in Hell, had caused sparks of jealousy to burst behind Sam's eyes. But he'd pushed them away. He only ever wanted Dean to be happy. And if that was not with him, so be it Sam decided.
It hadn't surprised Sam the first time Dean rolled over in bed and mumbled, “not tonight Sammy, 'm too tired.” Just as it hadn't surprised him when Dean had sat him down and explained that they needed to end what ever it was they had between them; that Dean was in love with somebody else. And it hadn't surprised Sam when Dean said quietly one night to not wait up for him, that he didn't know when he'd be back. Dean staring at Castiel as if the world revolved around the angel.
It hadn't surprised Sam; but it had hurt him. A deep, festering hurt that had grown, day by day until it had consumed Sam, body and soul.
Part 1
Sam watched from the shadows. Jaw clenching at the way they talked quietly, heads and bodies angled towards each other as the lovers walked across the almost deserted parking lot, arms brushing as they moved and he welcomed the emotions surging through him. Anger and jealousy clouded his vision. He's MINE! He wanted to scream at the filthy angel as he saw Castiel's finger stroke across the back of Dean's hand, desperately wanting to grind Castiel into dust.
Pushing away from the wall Sam strode towards the couple. Dean looked up at the sound of Sam approaching, shoulders tensing as he took in the look on Sam's face, the rage and possessiveness there.
“You should go, Cas” Dean said quietly to his lover, not wanting to test Sam's limits tonight. Sam was really starting to frighten his brother, and Dean didn't scare easily. Castiel stared at Dean before turning to look at Sam. Closing his eyes briefly, he nodded his head once. “Dean,” he started, but stopped as Sam stepped behind Dean, wrapping an arm around his chest, bringing the older man up against him. He placed his other hand possessively over his brother's stomach. Sam smirked as he watched Castiel's eye follow the movement of a finger as it dipped below Dean's waistband to caress the skin there, almost daring the angel to say something.
Dean pulled out of Sam's hold, “I'll be in in a minute” he said, voice strained. The pressure of the last few months, hell who was he kidding, of the last few years, was starting to get to him. He watched warily as Sam slammed into their room and sat on the bed nearest to them, leaving the door open so he could watch the men in the parking lot.
Castiel stared at Dean, the worry clear in his blue eyes. “I do not like leaving you with him Dean” he said, taking Dean's face in his hands to kiss him softly, “Dean!” Sam barked from the motel room forcing the lovers reluctantly apart. “I'll be ok, he won't hurt me” Dean assured the angel quietly as he backed away. Green eyes met blue and shared a message of love as Sam reached out to pull Dean inside, slamming the door on Castiel.
Castiel stood in the parking lot feeling lost and helpless. Feelings he was not accustomed to, had never felt before. One last look at the closed door and Castiel turned away, not sure what to do, but an inkling of an idea gradually forming.
Inside the motel room Dean turned on Sam, “What the hell do you think you're doing Sam?” he demanded, “I'm not 14! You do NOT need to make sure my prom date has gotten too fresh with me man.” Dean paced around the small space trying to bring his anger under control, not wanting to provoke Sam. It was like prodding a wounded lion with a sharp pointed stick. “I don't like that........that angel touching you” Sam spat at him, “I can smell him on you, see his grace on you.”
Dean just looked at Sam incredulously. “What the fuck Sam?” he said, “his grace?” Sam advanced on his brother, “Yes Dean. His grace. I can see it clinging to your skin, smell it on you. Do you like it when he fucks you Dean, does he make you scream the way I do?” Sam taunted, “Does he bend you over and slam in hard? Or does he take his time, make you beg for it like the cock hungry slut you are?”
Sam was standing so close now Dean could smell his unique odour. It used to arouse him, but now it just repulsed him. Bringing his hands up to push Sam out of the way, Dean found himself laying on his front on one of the beds, arms pulled tight behind him. Struggling to get free of the hold Sam had on him, Dean cursed and swore at his brother, desperately fighting to get his knees up under himself so he could push Sam away, all the time wondering where the hell the sweet little baby he had helped to raise had gone.
Sam's height and weight advantage was too great for Dean, even as strong as the older brother was, he was no match for Sam's new found strength. “Hold still” Sam snarled in Dean's ear after Dean had tried to buck him off again, and he moved to wrap one large hand around both of Dean's wrists.
“I hope you let Cas fuck you big brother,” Sam whispered as he unsnapped Dean's jeans, “because I'm not wasting my time prepping you.” Dean stilled at Sam's words and actions This isn't happening he thought desperately, Sammy wouldn't do this, resolutely choosing to ignore the little voice in the back of his head that said this wasn't Sammy, hadn't been Sammy for along time. Not since Dean had made the trade, and he was starting to realize that Azazel had been right. That what came back to life that day hadn't been purely Sam.
Fighting even more now, Dean tried to buck Sam off, twisting and jerking on the bed. “Hold still” Sam bit out as he unbuckled his belt and used it to tie Dean up. Both hands free, Sam rolled Dean over and stripped his jeans and boxers off. Dean kicked out as Sam bent down, knocking his brother over. Sam growled as Dean tried to get off the bed and fell on top of him, crushing the smaller man. Leaning away from his brother, Sam casually backhanded him across the face. “I told you to stay still” he said, and Dean stared horrified at his brother as the hazel eyes he used to drown in flashed yellow.
Dean lay on the bed panting, the taste of blood from his split lip increasing his nausea. The fight gone from him now he knew exactly what Sam had become. He watched helplessly as Sam took a condom out of his wallet and pushed his own jeans off. “I don't want to catch anything from that angel” Sam spat out as he rolled the condom on, smirking at Dean as he crawled between the obscenely spread legs of his brother and grabbed Dean by the hips, lining his cock up with Dean's hole. Ignoring Dean's pleading and cries to not do this, Sam licked a strip up Dean's neck.
“You're mine” he ground out as he slammed into Dean's unwilling body.
