Sam felt fear buzzing through his bones and rattling his normally calm façade. But there was something else too. It curled under his stomach in an unmatched heat that drove him to think what if? And why not? Lucifer ground their hips together and Sam forced his eyes closed. No, no, no, no, he screamed silently.

"Why?" Lucifer questioned heatedly into his ear, "What if I was Dean? Would you say yes then? Is that what you want? You want-. "

Lucifer's voice suddenly morphed.

"Big brother to take care of you?" Dean's gravelly voice grunted out.

Sam's eyes flew open to reveal that Lucifer had indeed transformed into his brother. Suddenly all the air sucked from the room as Dean stared down at him, tongue hanging out as he panted against Sam's face. If Sam had felt dirty before, it didn't compare to how dirty he felt now. He shivered and shuddered, wishing he could see anything but his brother's lust filled face.

"N-n-no," he whispered, jerking his wrists weakly, "N-no."

Dean's face smiled in surprise at him and quickly shifted back into Lucifer's face or rather, the face of his vessel.

"Not brother dearest then?" Lucifer said amazement evident in his voice, "How about your guardian angel then?"

And suddenly sweet, innocent Cas was staring down at him hunger-darkened eyes. The heat spiked in Sam's gut as Cas grinned down at him in a predatory way. But it wasn't right, it was wrong and dirty and left Sam squirming away.

"No!" he croaked as Cas's face leaned down to lap at his neck.

Now as the devil returned to his own face he had a look of true confusion there. Then his face brightened as he thought of something else. Now Sam saw Jessica staring down at him. Jess smiled sweetly and moved to gently press her lips to his. He screamed and spat up at Lucifer, unwilling to see Jess any longer. Lucifer cocked Jess's head to the side and his face moved back to his own.

"I don't understand, Sammy," Lucifer said, true confusion ringing in his voice, "Who is behind that lust? Who's in there, bunk buddy? Who's in that dark little corner of y-?"

He froze suddenly, the question hanging in the air. His face opened in a wide, wolfish grin.

"Oh, you are naughty," he chuckled darkly, "Fantasizing about the devil? What a bad boy."

Sam frantically shook his head, his whole body shivering from the lust laced words.

"And now you try to deny it?" Lucifer questioned, his face mocking and sneering, "I can see that dark corner now, Sammy, baby. You can't hide it from me anymore!"

Sam whimpered and tugged at Lucifer's hands rather pathetically. He knew he was trapped and part of him didn't care, but the larger part of him was trying its best to squash that husky voice in the back of his mind. Aw, come on, Sam, there's nothing wrong with a little fun. You never get to do anything for yourself, so go ahead and have some fun, it whispered seductively from its corner. Sam groaned, his eyes fluttering closed. He ached with all of his body to let this happen, but his common sense was slapping him and reminding him that he had to help Dean.

"Dean," he muttered.

"I thought you said no to Dean?" Lucifer laughed.

"I have to…" he trailed off as Lucifer pressed hard against his hips.

He felt the outline of something hot and hard through his jeans and he didn't have to guess what it was. It rubbed roughly against his own, sending thoughts, pictures and want flowing through his brain and blood. He let out a strangled whimpering moan of want that bordered so close on need it made his knees weak. Lucifer's hot breath was once again at his ear.

"Alright, alright," it whispered heavily, "Go save Dean, if you must. But I don't want to hear his name ever again. That damn hunter is starting to become a pest. He is ruining all of my plans."

The hands on his wrists tightened briefly as a mouth smacked down on his own, sloppily and openly kissing him before it and the body it belonged to was gone. Sam let out a shout of exasperation, his hand immediately flying to his crotch. He wasn't sure if it was sexual frustration or just frustration in general, but he was done with himself within a minute. He groaned in disgust at himself before stumbling back to life.

And wherever Lucifer was, Sam could bet he was laughing.
