"I need to see Dean," Cas's wings flapped, he turned in a little circle, searching the library for Dean. "Where is he?" Cas did that little head tilt that made Sam mad. He acted and looked so innocent, but oh the things he was capable of. Dean always hogged him. Barely ever letting Sam talk to him.

"Dean's gone. He's out with an old friend, why?" Sam squinted his eyebrows, carefully examining Cas's neatly dressed body.

"A female friend?" Cas asked confused.

"Y-Yes." Sam chuckled a bit, tucking a piece of hair behind his ear and sitting down in a wooden chair, sipping a half filled glass with whiskey.

Cas shrugged, taking a seat next to Sam. "Can I have some?" Sam gave Cas a 'Are you serious or..' face. Sam gave a little nod and poured Cas a cup of whiskey, looking into his eyes as he handed it to him. Cas threw it back like nothing, biting his bottom lip as he looked at Sam.

Sam swallowed loudly. Trying with all his might to hide his obvious red cheeks and sexual attraction to Castiel.

"What is it, Sam?" There it was. That face. Those lips. Fucking Castiel.

Sam stood up tugging Castiel by his blue tie, bringing their mouths inches away from each other. Sam brushed his lips lightly against Castiel's, nipping his pink pouted bottom lip. It was too much. Sam needed to fuck Cas. With or without his consent.

"Sam, what are yo-" Cas squeaked, not pulling away but not approving either. Sam's hand grabbed ahold of Cas's sex, feeling it harden under his touch. Sam's free hand ripped open Cas's white dress shirt, hearing the buttons hit the wooden floor.

"You know damn well," Sam snickered, rubbing Cas through his pants. "You aren't as innocent as you seem, Castiel. And I'll prove it tonight." Sam's hands unzipped Cas's slacks viciously, yanking them, along with his boxers, to his knees. Sam got on all fours, stroking Cas's free member with his tongue. "Tell me what you want." Sam looked into Cas's eyes, no stopping his kitty licks.

"I want you." Cas breathed, sitting half of his weight on the tip of the library desk.

"Be more specific, Castiel." Sam continued teasing Cas, making it harder for him to squeak an answer.

"I want you to fuck me, Sam." With those words Sam fully took Cas into his mouth. Cas gripped the desk so hard his knuckles were white. Cas grumbled lowly, throwing his head back as a shiver ran down his back. Sam bobbed his head roughly, pushing Cas near climax with each bob.

Sam pulled away, causing Cas to frown and give a pouty face. Sam fully stood up, bending Cas over the desk he leaned on momentarily. Cas heard clothes hit the floor, sexonds later Sam's fingers started rubbing Cas's virgin ass, preparing it for a good fuck. "S-Sam." Cas moaned, letting Sam explore his body.

"Shhh." Sam's voice trailed off as he plunged a finger into Cas. Cas grunted loudly, gripping the wooden desk again. Sam plunged in two, three, four fingers inside Cas until he was ready. Sam roughly tugged Cas's hair, making it so Cas was staring sideways into Sam's dark eyes. Sam groped his member, aligning himself with Cas.

Sam thrusted into Cas, not wasting precious time without Dean around. Cas cried lowly, gripping the desk harder from pain and pleasure. Their eyes burnt in a long stare, only stopping to blink. Sam tugged on Cas's hair again, bringing their bodies closer together. Sam's breath hitched as he picked up the pace, letting his free hand snake around Cas to stroke him to climax. "SAM!" Cas moaned, whining. Sam brushed his finger over the tip of Cas's eagerly attention needing dick.

The bunker was quiet except for the grunts and repetitive slapping sounds. Sam's hand worked savagely, not even considering slowing down until Cas was undone.

"I-I-" Cas arched his body into Sam's as he came, not being able to finish his sentence. Sam groaned at the feeling of Cas tightening around him and climaxing in his fist.

Sam wouldn't last much longer. Just the thought of everything that was happening drove him up the walls. Cas, being his little fuck doll. Letting Sam take his virgin ass. That was it. Sam came. It was the best climax he's ever had. And he's had plenty.

"FUCK." Sam gripped onto Cas's ass hard enough to leave a mark for Dean to find later.

Sam pulled out of Cas, panting as he slipped his boxers back on. Cas snapped his fingers, dressing them both as the front door opened.

"Hey, I'm home, Sammy!" Cas slid off his blue tie, handing it to Sam and then disappearing.

"Hey," Dean walked into the library, drinking the left over whiskey in Cas's cup. "Two?" Dean arched his right eyebrow.

"U-Uh yeah. Yours. Listen, I'm gonna go to bed. Night." Sam scurried to his bedroom, clenching the tie in his hand as he locked the door and flopped his tired body into bed. He reminisced about Cas the rest of the night, barely being able to contain himself until next time Cas dropped by when Dean was gone.
