Castiel’s breath huffed out in an awkward ‘oh’ of shock. “Sam. What are you doing here?” He wasn’t accustomed to being taken by surprise, but Sam still had the wardings on his ribs that made him invisible to angelic detection, and Castiel had been…distracted.

He could easily overcome the hold of Sam’s hand gripping tight on his shoulder, the other pushing over his heart and guiding him back, but allowed himself to be pressed against the side of the garage. He did not want to draw the attention of the occupants he’d been observing next door, currently seated around the dinner table and conversing over their meal.

“Easy, Cas. You wouldn’t want to get caught, would you? I came to see my brother, get his help on a hunt."

He couldn’t figure out what had gone wrong with the retrieval, but he was almost grateful Sam had never deigned it necessary to contact his brother. That he was here now was worrisome.

“That is not advised. Your brother is retired from hunting. You shouldn’t bother him with such matters.” He kept his voice low but forceful, the anger that Sam would disturb Dean’s domesticity obvious in its rumble.

Castiel was uncertain what the expression in Sam’s eyes could mean as he further invaded his physical space, molding their bodies tightly together. The way he was scrutinizing him was too cold, too calculating, and not even close to resembling the Sam he remembered from before his descent into Lucifer’s cage. Sam smirked and leaned closer to continue, whispering into his ear. Hot air stirred the small hairs at his neck and warmed his skin, cool from so long standing still in the dark.

“You’re in love with him, aren’t you? This isn’t the first time you’ve come here. You’ve probably been stalking him all along. Watching him when he doesn’t know you’re there, seeing him completely off-guard. Do you watch him when he’s with Lisa, Cas? Stand beside their bed and watch him fuck her?”

Castiel froze, shocked. He didn’t understand how Sam could know such a thing. His presence should be undetectable to all but another angel and he was always careful when visiting so that his brothers would never find out Dean’s location.

“I bet you pretend it’s you he’s fucking, opening you up and splitting your tight virgin ass on his cock.” Sam’s hands were suddenly pushing at his clothes, pulling his jacket and trench coat down his arms to be discarded at their feet, and Castiel shivered in the evening air.

The vessel he wore was completely his own but still mystifying in its reactions to certain stimuli. Sam’s pronouncement made Castiel hang his head. He wanted to hide away but also be closer, so he buried himself against Sam’s chest. The way Sam’s body was rubbing against his, all heat and controlled strength, was making his heart race and his breath quicken. He felt small in Sam’s hold, subservient, and even though he knew it would take but a thought to get free, he didn’t want to.

“I can show you what it would feel like, what it would be like to be fucked. You want to know what it’s like, don’t you? Do you trust me, Cas?” Sam’s hand was rubbing distractingly under his shirt, caressing over his stomach and dipping into his waist band.

He felt something fluttering inside him, a pleasurable heat beginning to spread from deep in his stomach and tightening his skin, and the sensation was fascinating. He realized his hips were moving without his express will, undulating slowly against Sam’s firm thigh. There had been a question…Sam had asked if he trusted him.

“Of course. You are my friend and I would travel into…yes, Sam. I trust you.” He was becoming too wrapped up in Sam’s hands, his mind muddled. He wanted Sam to touch him more, teach him all about the pleasures his human body could experience.

“Good. Now don’t make a sound, Cas. Dean is real jumpy and if he hears you, he’s gonna come investigate.”

Castiel nodded, showing Sam his obedience and trust, and saw Sam’s eyes change in a moment, turning dark and predatory but lit up with an inexplicable triumph. Then he was wrenched around and pressed face first into the cool plastic siding of Dean’s neighbors’ garage.

A gasp punched out of his lungs with the rough treatment but Sam was there to help stifle it, his hand coming up to grip his mouth tight. “Quiet or I’ll stop,” he whispered into his neck before biting down, and Castiel was thankful for the callused palm pressing over his lips as the bite forced another small whimper from him.

“God, Cas. Can’t wait to fuck you, gonna wreck you.” Sam was rolling his hips, thrusting against him, and Castiel pressed back for more. It was good but he continued to feel unfulfilled, like there was more to this and he had to have it. It was difficult to remain passive, but he wasn’t sure what it was he wanted and was determined to keep his promise to trust Sam.

His shirt was ripped open, buttons flying and pinging off the side of the garage, but Castiel was unable to track their progress as Sam was pinching at his chest, rolling and tugging on his nipples. Castiel arched his back, leaning into the touch, willing Sam to do it harder, give him more of the strange and compelling feeling. Sam’s large body took his weight easily, so strong and burning hot against him.

“Look at you. You’re a slut for it, aren’t you? I bet I could turn you around, feed you my cock ‘til you choked on it and you’d ask for more,” Sam huffed into his hair as he rutted against him, cock huge and thick, riding the crease of his ass.

He hummed his agreement, forgetting not to make noise, only wanting to answer Sam in the affirmative that he did want more, even if he wasn’t exactly sure what more entailed. But Sam’s hand was still there to ensure his silence, his fingers starting to thrust into his watering mouth as if in answer to Castiel’s questioning thoughts. Suckling at Sam’s long fingers was making him edgier, made his desire sharpen.

“Good. Get them nice and wet. Jesus, fuck, those lips. Gonna make you so fucking dirty, stain the innocent Angel of The Lord. Your mouth was made to be used, but first….”

Sam’s body shifted back from his and he heard a clanking he could only assume to be the hunter’s belt being undone. His theory was confirmed when it was followed by the unmistakable sound of a zipper being pulled.

Then that hand was back, tugging at Castiel’s pants and undershorts until they pooled around his ankles, his flushed skin breaking out with goose bumps as he continued sucking messily at the fingers in his mouth, saliva leaking out around the digits and making his chin wet.

Sam pulled his fingers out with a pop, Castiel chasing them with his tongue and a small whine of disappointment he didn’t mean to make.

This body was seemingly acting on its own and Castiel wanted to exert more control over it but was afraid his ability to feel this pleasure would be dulled if he did and he didn’t want to risk that.

“I’ve got what you need, Cas, and I’m gonna give it to you, but you need to be quiet. Not a fucking sound, or I’ll stop.”

Sam pulled his hips back so he was forced to catch himself against the garage. Castiel buried his face into the bend of his arm so he wouldn’t accidentally make any noise, and then Sam’s fingers, wet from Castiel’s mouth, were running down his crease. They circled in on his hole, hastily rubbing the makeshift lubricant around before plunging inside with one firm thrust.

Castiel was glad he’d covered his mouth because he let out a deep moan at the penetration, unprepared for the intensity. The burn and the stretch was exquisite, like nothing he’d ever imagined. It was making him hunger, an echo of the want Famine had aroused in him, but this time his hunger was for Sam and what his touch could do to him.

He heard Sam gather saliva in his mouth, a moment later felt the wetness of it sliding over his tailbone to add to the moisture from his own mouth, and Sam’s fingers scooped up the spit and forced it into his hole, getting him ready.

Castiel’s stomach felt wet. He looked down to see his penis standing erect between his legs, the tip flushed red and leaving sticky trails on his belly. He wanted to touch it but was afraid to move lest he make some sound, forcing Sam to make good on his threat to stop.

“Are you ready, Cas? You better keep your mouth shut or Dean’s gonna catch us.”

Sam gripped his hips and pulled Castiel back onto his dick. The head of it was smooth and wet, so hot against his sensitized entrance. Then it plowed into him and he couldn’t hold back, letting out a loud cry.

Sam stilled instantly, buried deep inside him, their bodies flush together, and Castiel was trembling, unable to catch his breath, completely overwhelmed by the fullness of Sam’s cock. The stretch was even more intense than with Sam's fingers, splitting him so wide, but it was so good and he felt so much, Sam’s cock inside him grounding him completely in the physical.

He tried to calm himself, making an effort to relax his muscles and regulate his breathing, and Sam moved to cover his mouth again, broad palm pressing firm to his lips and pulling, his back arching under the pressure. Sam started to withdraw, dick pulling against his insides, burning, the edge of pain just adding to the pleasure, until only the head was left inside before thrusting back in with seemingly all his strength, the angle making the penetration that much deeper and sparking starbursts behind Castiel’s closed eyelids.

The slide in and out continued at an unhurried pace, deep and rough, forcing him up onto his toes with each slam of their hips. He could feel himself grunting, hear Sam’s breath huffing like a wild animal, and knew they weren’t being quiet enough but just couldn’t care with Sam taking him this way.

His own dick was bobbing between his legs, leaking trails of hot wetness down his shaft and over his sack. He wanted to touch himself, press down tight and squeeze, sure that it would help alleviate the pressure that was building up with each deep stroke of Sam’s cock. He only held back because he couldn’t find a way to move his hands from where they were bracing himself against the garage. The way Sam was moving within him so roughly was sure to slam him into the siding.

He couldn't help the blasphemous mental blessing he gave to His Father when it seemed like his prayers had been answered by Sam’s fingers moving from his hip to encircle his cock, a thumb running over the tip and spreading moisture slick over his shaft. The pressure was like a Godsend, almost exactly what he needed until Sam suddenly stopped fucking him, grip cinching tight around the base of his dick.

Castiel wanted to protest but Sam had him well trapped and then he heard it – soft footsteps and the crinkling of a plastic bag.

He opened his eyes in alarm, gaze searching in the dark and landing on Dean, only a few yards away. He stopped breathing, both he and Sam caught in almost preternatural stillness.

Dean lifted the lid on a garbage can and deposited a large plastic bag inside, his bright, beautiful eyes combing over the surrounding shadows and passing right over them, so close that Castiel imagined he could smell the leather and whiskey flavor of Dean’s skin. His dick pulsed in Sam’s grip, his muscles squeezing tight around Sam’s cock and making Sam gasp.

Dean turned around, never seeing his brother and his angel fucking in the shadows of the house next door, and went back inside to his new family.

Sam’s grip let up, moving back to stroke him hard and fast as his hips started to piston in and out, the pace brutal but pushing Castiel right over the cliff into orgasm. His body seized up, mouth open against Sam’s hand letting out a choked groan, as his cock spurted so hard it hurt, come painting the plastic siding in dripping rivulets. Sam groaned into his neck, reaching his own peak and flooding him with heat.

They caught their breath, locked together and riding their pleasure before Sam pulled free, some of his come following to seep down Castiel’s perineum.

Castiel couldn’t believe that humans got to feel this every day. His Father was truly magnanimous in his Gifts. He understood why people would go to such lengths to achieve such a joining. How wondrous it must be to do such a thing with a person you loved.

By the time Sam was tucked back into his pants, Castiel was once again clean and fully clothed, looking exactly as he always had, not a trace of the pleasure he just experienced showing in his outward appearance. He faced Sam, looking at him as close to pleading as he was wont. “Please, do not disturb your brother.”

Sam studied him, eyes lazy and satisfied like a serpent that had just feasted and wanted nothing more than to lie and bask on a warm, sunny rock. “Okay, Cas. You’ve been very…,” his eyes traveled slowly over Castiel’s body, like he was still seeing Castiel spread wide, taking his dick, “…convincing. But I’ll probably be back and you won’t always be here to ‘protect’ him from me.”

“I will try,” he answered, knowing that he couldn’t keep the brothers apart forever and that Dean would not thank him if he did.

Sam’s answer was a smile, almost warm but still with a predatory hint. “I look forward to it.”

And that will pop my fic posting cherry on LJ. :P
