The hunt with the demons hadn't gone as well as planned, the Winchester brothers had fought as hard as they could. Destroying the hellish beings one after another but when the brothers were separated, Dean was possessed.

The demon enjoyed his new meat suit, taking control of a Winchester was certainly a win. Not only that, but Dean and himself were alpha, and Sammy was a sweet omega on the verge of heat.

That was going to be fun.

Sam groaned, pain and heat building in his belly. Dean watched him carefully, smelling his brother's heat coming off of him, he was always very careful and considerate around Sam when his heat was starting, and the demon wanted to let Dean's personality show through until he could pounce at the hotel.

Sam whined again, calling to Dean and the demon that was inside of him. "Almost back to the hotel Sammy, I will get you a drink and something sweet alright?"

Sam nodded at his brother's words, it was the only time he cared for sweets in any capacity. Dean could smell Sammy's sweet scent wafting around the car. He gritted his teeth, he felt awkward finding it appealing, but his cock twitched as Sam's heat began to rise.

They got back to the hotel, and Dean got Sam onto the bed. They had a deal, Dean would get him something sweet and a beer to soothe him, and then he would usually leave him alone in the hotel room going to swindle alone at a bar, or he would stay but lay in bed and put in headphones while Sam went to the shower to play with knotted toys.

Sam groaned, curling in on himself in an attempt to ease the pain while he waited for his brother to get him a drink and leave.

Dean groaned a bit, feeling his hard on pressing against his jeans, he moved into the kitchen and grabbed a beer from the fridge and a slice of pie. Then there was a switch flipped, and he was on autopilot. He grabbed for some meds in a bag they had, and slipped them in the beer. He also slipped some in the pie. He wanted to make sure his little brother wouldn't remember a single thing.

Dean waited a moment before bringing him the beer and the pie, Sam didn't even stop to chew the pie, he drank the beer and asked for another one knowing it numbed the pain. He quickly took another bottle from Dean who watched Sam with dark, hungry eyes. The sleeping pills took over quickly, Sam began to grow groggy, unsure what was going on around him. "D-Dean?"

"Don't worry Sammy, you're okay." Dean said with a more unkind tone than usual. "Don't worry puppy, your big brother had you."

Sam gripped his shirt as his legs buckled. Dean pinned him to the bed, working his clothes off quickly. Sam groaned, trying to fight back but his movements weren't fast and had no power behind them. Sam whined as Dean pulled his jeans all the way off and used his belt to tie Sam's wrists above his head.

Sam cried out as he felt it tighten around his wrists. "D-Dean?!" Dean slid his fingers inside of him, stretching his virgin hole a bit, but the demon could simply tell by the twitching in Dean's pants it would likely not stretch him enough to help.

"Shh Sammy, you won't remember this tomorrow." Dean growled as he pulled his own pants off. Sam strained, pulling at the restraints, whining again for him.

"Pl-please.."

"Shh lil brother it will be okay," Dean grunted. "Don't fight, it will make it worse." Dean chuckled as he ran his finger along his wet cunt, slick sticking to his fingers.

"Ngh.. Pl-please.." Sam whimpered, his eyes closing for a moment as the sleeping pills took over.

Sam strained, pulling on the belt around his wrists. His vision blurred again, his head falling back to the side before the head of Dean's cock slid between his wet folds. His head popped up and he let out a cry. "Fuck, puppy, you're so tight..." Sam gasped out as Dean stretched him out as he slid inside, his cock long and thick. Sam pulled on the restraints, crying out in pain. "Fuck.. so tight.. You feel so good."
