Work Text:
Every weekend, it's always the same. Another frat party with the same drunk idiots. And that's why Cas hasn't been to one in a while. They've gotten so boring. The years have jaded him, he's not the starry eyed freshman anymore. But he was promised a good time, and after this much talk, Cas has to admit, he's very curious to meet the new recruit that has the whole house abuzz.
Tonight didn’t start out as anything special either. Same old, same old. But once again, he was promised it would be well worth the wait. So he drank and he had a couple bumps and he waited. His Brothers didn’t tend to disappoint him. They must have something huge planned to liven his spirits.
Upstairs was completely roped off, members only, and after a couple hours, Cas was finally ushered upstairs for the big reveal, allured with the promise that the party was just about to begin.
He's pushed into an overcrowded bedroom, stuffed to the brim with familiar faces, all clamoring around the mattress. Everyone's cheering and jeering, red solos up in celebration, flashing lights from phones taking pictures. It's all a blur. Cas can't make sense of what has everyone's attention so he weaves through the swarm.
And then he understands.
A boy’s being held down to the bed and forcibly stripped.
“What's going on?” Cas asks, voice drowned out by the clamoring of his brethren.
He's weary but not shocked. Fraternities can get pretty out of control, especially with things like hazing, especially the chapter Cas oversees. The poor victim must be the new recruit. And by the looks of things, he's blasted out of his mind. Unable to even hold his head up properly.
Hazing isn’t exactly on his list of new and exciting things, but regardless, he stays to watch and see how things progress. Curious to see what sort of prank they're positioning him into. To take scandalous photos or something, surely. Tie him up and leave him there. Maybe even whip out the paddles, teach him a lesson about overindulging. It's childish but Cas finds himself preemptively laughing, anticipating the end goal, whatever it may be.
Newbie is tossed to his stomach, arms outstretched and wrists held to either corner of the bed by a few of his soon-to-be brothers. His pants are yanked off his legs, his ass exposed and in the air. A green gemstone plug glinting in the light. And yeah, Cas has to admit, that's pretty funny. He's had to do something similar. Wear a butt plug all day during classes and get mocked relentlessly. Pretty standard stuff. Most of the men here have done something similar. Hazing is juvenile but it is required for admission. It's the price they pay. Enduring is a privilege. When you're no longer new meat, once you’re the President or an officer and you’re orchestrating Hell Week, hazing can get pretty damn fun.
The boy is barely able to fight back. Squirming away from every touch. Cas thinks he even hears him slur something like: get off me, get off me, but he can't be sure. The raucous is loud when it's mixed with the deafening music blasting from nearby speakers.
The plug gets pulled out of him and thrown to the other side of the room. Cameras are going wild. Poor kid will be reminded of this night forever. And then someone's knee walking up the bed and unzipping their jeans and the taste in Cas’ mouth goes sour. What is happening?
A little put off, Cas watches Benny– his number two– pull his dick out of his pants and slap it against the recruit’s ass cheeks and everybody roars with laughter. Despite the sour taste, Cas can't help but smile. So glad to be a senior rank these days.
Another brother gives him lube and Benny slicks himself up and plunges into the recruit’s ass. More laughter erupts and Cas detaches himself from the act. Mostly because he can't quite process the fact that it’s really happening. If this was going too far, someone would stop it, right? And no one's stopping it. Usually, if there’s something like penetration, a foreign object is used. This is… an escalation of tradition. So Cas just watches as Benny plows roughly into the newbie– only about a minute before he's pulling out to leak come onto his lower back.
There's cheers and more pictures and somebody mocks him for how quickly he finished. He must be a fag if a twink got him off so quickly. Benny tells them all to shut it and try out for themselves and it's less then a second before Victor steps up to the plate, unbuckling his belt, ignoring obscenities being shouted at him from the newbie.
Benny sidles up next to him, elbowing him in the side like hey didja see me out there and Cas raises his eyebrows like yes fantastic work. It's all so automatic. He doesn't even have to think about it.
“I can't believe Dean got wasted so easily. Kid needs to pace himself.”
“Dean, huh?”
“Yeah, isn't he great? Recruited him myself last week. Loads of potential.” Benny jokes and they watch Victor slap his ass, laughing, saying how they should put a wig on him so he looks prettier. Then he makes a horribly ugly face and he also pulls out to come up his back and another man is already rock hard and waiting for his turn.
Cas looks away from his brothers’ junk, the last thing he wants to see, and watches the recruit’s face instead. Babyfaced. Soft, full lips. Freckles. Dean. There's something special about him.
Cheek smushed against the bed, body rocking in time with the thrusts of whoever's taking him now, and Cas can see the moment he resigns himself to them. He grits his teeth, fists his hands, and doesn't say a word. Breathing through his nose. He stops fighting.
Dean's focus looks bleary, even from Cas’ point of view. Dizzy from the alcohol, slipping out of awareness. And then his gaze lands on Cas, sharpening, and suddenly Cas can't breathe.
What was gay two seconds ago, is suddenly the time to beat. They pass around Dean like a joint and time each other on who's the fastest, who's the champion. And Dean ignores it all, eyes locked in on Cas, and Cas can't look away. Doesn't want to.
“Looks like he's got a crush on you, Prez.” Victor jeers but Cas has no response to that. He thinks the feeling might be mutual.
Ash is up next but he's got whiskey dick so it takes him a long while, the biggest loser by default, with Benny still in the lead. And Dean takes it all, close lipped and determined to not show weakness. Some brothers claim they have no interest but stand close to jerk themselves off on Dean anyways. He's covered in a fraternity’s worth of come and he still can't take his heavy lidded eyes off Cas. Almost everyone has had a turn using him. Almost.
Benny slaps him on the shoulder and says, “You're up, Monster.”
Cas is well respected in this house because of how big his cock is, earning him the ridiculous nickname.
Cas is so detached, so painstakingly hard, and so zeroed in on Dean– there's nothing left to stop him. Cas keeps eye contact and slowly pulls himself out to show Dean what's about to be inside of him.
For the first time all night, Dean’s eyes leave his face and fall to his cock, eyes wide and frightened.
“I think he's in loooove,” Benny snides and the swarm of men laugh and laugh.
He pumps himself, fingers barely not able to close around himself and Dean swallows nervously. Let's see him hold back now, Cas thinks smugly.
Kneeling onto the bed between his legs, Cas lifts his hips up to inspect his abused hole. Puckered pink. Pretty. Close to gaping. He might actually be in luck tonight.
He slicks himself up and gently breaches his hole and Dean gasps and tries to twitch away but Cas, along with his brothers, hold him firmly in place.
Cas slides in an inch and all Dean can do is inhale and brace himself. It's a slow and agonizing stretch, and Dean's ass is hot and so fucking tight as he squeezes inside another inch. Dean whines at the feeling of being split open and Cas deems that tonight was indeed worth the wait.
He's only half way in but Cas starts shallowly thrusting and beneath the whooping and the chatter, he hears Dean muffle into the bed, ahhhhh holy fuck.
The suctioning grip is so good but Cas is feeling greedy and knows that Dean can take more. He hardly ever gets this far with anyone on campus, no matter what their reputation says otherwise.
The crowds cheering, in shock and awe, saying things like”
Good thing we warned him up for ya, Prez!
God damn, don't kill him, Monster!
Cas crams in another inch and Dean’s eyes roll back and Benny cheers: he’s loving it!!
And of course he’s loving it, Cas found and rubbed against his prostate. He stops there and shows it some more attention, aiming for it with every thrust and Dean’s groans gets louder and everyone mocks him with their own, chanting for the monster.
And it was funny at first but now Cas is getting pissed that he can't hear him. Opportunities like this are rare for him and everyone is ruining it by drowning out Dean's pretty cries.
“Enough. Get out!”
Everyone falls quiet, kinda giggling like he might be joking.
“I said: GET OUT!” He bellows.
Benny claps loudly and says, “Alright, you heard the man!! Move it!!”
Benny ushers everyone out of the room and he whispers in his ear, “Merry Christmas, from all of us,” and the gesture actually does warm his heart a little.
His men boo and whine and say he's no fun but eventually– finally – they're alone. Cas made even the ones holding him down leave, Dean's arms speckled with bruises.
The music is still rumbling but it's insanely quieter now that it's just the two of them.
Cas starts his small thrusts again, just shy of Dean's prostate, warning him back up.
“It's a pleasure to meet you, Dean. My name’s Cas. Friends call me Monster.”
Strung out after 11 cocks, all Dean says is, “Hi, Cas.”
Cas grazes his prostate and Dean grips the sheets, groaning and shuddering.
Again and again and Dean’s a mess of overwhelmed noises.
“I'm gonna take good care of you, newbie.”
He's stretched wide and he's trembling. Cas pours more lube on them, entranced as he slides in and out slow slow slow, taking his time with his precious gift, determining just how much Dean can take.
He starts to roll his hips, eliciting more delicious moans out of Dean. He's given up his battle of being stoic, no longer taking it like a man. It feels too good to be quiet.
“Oh, listen to yourself. You're a whore, aren't you, Dean? I bet you're hard too, aren't you? I bet I could make you come without touching you at all.”
Cas reaches for him, delighted to find that he's right. Dean's hard, hanging heavy between his legs. He whimpers when Cas touches him.
“Awe, don't be embarrassed, honey. It's not your fault.”
Cas presses into his prostate again and again and Dean’s moaning, taking it well, even pushing back for more.
“God, that's it, don't be shy, stuff yourself with my monster cock. It's all yours. Oh fuck, your feel so fucking good. Such a tight, accommodating ass.”
Dean's eyes are closed in rapture, white knuckling the bedsheets, meeting every thrust willingly, mouth open, heavy panting and moaning, losing himself, stuffing himself, absolutely covered in come that continues to drool off his back down along his shoulders
He's tired of holding back. He wants to see Dean take everything he's got.
He slides several more inches in until Dean’s flush against him and Dean's inhale builds into something high pitched. Cas holds him there and grinds dirtily to wedge himself in deeper, just because he can. Being fully sheathed by somebody else is a novelty. Can count on one hand how many times he's accomplished such a feat, and never with anal, never with a boy as pretty as Dean.
Dean is wincing and tense and shuddering and his ass feels like heaven.
“Shhhhh. Relax for me. I don't want to hurt you.”
Cas rocks softly, showing great restraint as the newbie breathes and adapts to his full girth.
“Mm just like that, Dean. Your ass is a perfect fit.”
Every thrust, Dean groans a little throatier, loving the stretch.
Cas experiments with sliding all the way out and plunging back in and Dean's reaction doesn't disappoint, gasping like he's jumping into a cold lake
Cas does it again, long slide out, quick push it, slamming and smacking against Dean's ass. He cries out and Cas does it again and again and Dean takes him completely, quivering and gaping.
Cas is in love. His final year is really looking up.
“I'm going to fuck you now.”
He picks up the pace and Dean moans loudly, out of breath, gripping him tight, skin slapping and god, isn't it an awesome sound?
“That's it, that's it, take my fat fucking cock.”
Cas barrels into him hard and fast. Dean cries and whines and shakes from the assaulting thrusts, his whole body tensing and bucking against Cas, and just as it’s happening, Cas can’t believe he was right. Dean arches and buries his face into the mattress and comes screaming, and Cas is flying high, moving quick, slamming in and in and in and in, no longer caring if it hurts, taking Dean for all he's worth. Carving a space out for him and only him, making Dean his perfect Cinderella.
Dean is sated and limp and taking it like a champ as Cas holds him up, hole gaping wide and fuck Cas can't believe how beautiful the sight is. His grunts grow animalistic, rough and sharp. His cock throbs and plugs Dean full of come. Again and again, he can't stop spilling into him, draining himself into Dean. Deep, deep, as deep as he can, riding his ass like he could go any deeper but he can't. Fuck, he really can’t. Dean takes him all.
Cas won’t stop fucking him, dazedly watching his come ooze out of Dean’s abused hole.
“I feel sick,” Dean mumbles, immediately puking over the side of the bed and Cas takes his cue to finally pull out, Dean's ass splayed wide and leaking as he spits out the scraps of puke left in his mouth.
Cas sighs, not the ending he wanted for them but he supposes the one that was unavoidable. He puts his cock away and briefly leaves him there to wet a washcloth in the adjoining bathroom and comes back to mop up the slop of come on Dean's body. As much as he can anyway, covering him with a towel afterwards and helping him sit up.
“Come on, come with me.”
Dean can’t walk, he can barely stop from swaying, so Cas props himself against Dean and drags him to the bathroom, plopping him in front of the toilet just in time for Dean to heave again.
Cas sits beside him, rubbing his toweled shoulders.
“That's it, get it all out,” he soothes.
Dean alternates between puking, laying his head in Cas’ lap, and back to puking, over and over, and throughout the night, Cas notices a wet spot from where his come is leaking out of him. Dean’s an absolute mess and Cas can't help but be charmed by him.
He spends the rest of the night with him there on the floor, watching over him, and Cas thinks, no matter what happens, he'll remember this night forever for the both of them.
In the following months, Dean becomes his protégé and willingly enlists as his cock slut and Cas grows infatuated with him. Obsessed with the boy who can regularly take his cock like it’s nothing. Champ has become his nickname within the Brotherhood. And although that's where his name comes from, nobody mentions the gangbang again, least of all Dean. He's just happy to finally have a place where he belongs. Cas is happy to finally have a place he belongs as well, and that place is inside of Dean.
They’ll move in together before he graduates and Dean will spend more time with Cas than he does with anyone else.
