“Aziwapale! Look! I got so much candy!” Aziraphale looked down at his little brother and ruffled their hair. The poor kid had lost their front teeth in the past couple weeks and couldn’t pronounce anything properly anymore. Being ten years older than his adopted brother meant that he was in charge of taking them trick or treating and other kid events while their parents were off being important within society. Even adopting Anthony, a lower born omega, was done just to make themselves look better.

Aziraphale didn’t mind though, he loved his little brother and would do anything to take care of them. He had even planned his future around being able to take care of Tony without the influence of their parents. So far they hadn’t been able to corrupt the little one with their perfect idea of what an omega should be, but Tony did like the presents and fancy clothes they got to wear to parties. Said it made them feel very grown up.

As a small hand took his larger one, Aziraphale looked down to his little brother dressed as a bumble bee who smiled up at him. “Big bwother, are you my alpha?” The question was so innocent and soft that Aziraphale couldn’t help but stop walking towards the next house. “Why do you ask that, Tony?” The little boy shook his head a little and kicked a small rock scuffing his shoe on the pavement. “Mama said I have to grow up good for my alpha and that I should always listen to them. But you are the only one I know and have to listen to.” The little pout of confusion that followed completely endeared Aziraphale.

“No, I’m not your alpha. I promise to protect you though, you will never have to worry about being good for anyone but me.” Aziraphale then pinched the other’s little cheek until they giggled and demanded more candy. It was something the older boy had thought about, but he didn’t want to worry about what kind of mate his little brother would be attached to in the future and if it had to be anyone, he would rather it was him.

///////////////// 20 Years Later //////////////////////////////

Aziraphale sat down his book when he heard the quick steps from upstairs begin to move to the stairs before a head of bright red hair, perfectly curled appeared from under a witch’s hat stopped at the bottom of the stairs in front of a large mirror by the front door. Looking at the skimpy dress his younger brother had decided to wear for some party or another, Aziraphale couldn’t help but admire their long muscular legs and thighs peeking out from under the tulle fabric. “Must you dress like a tart every year, Anthony? I am certain there are different costumes for omegas that cover more skin.” The cheeky grin that was sent his way was exactly what Aziraphale was expecting from his brother in response.

“Ugh, I told you that I go by Crowley now. Anthony Jebidiah Fell is just too fancy for me. Besides, I have to dress sexily if I have any hopes of getting an alpha to mark me before I get too old and am considered a spinster!” Crowley’s voice was bright with laughter. When their parents passed away in an accident, the news that Crowley was adopted finally got revealed to the red head. While they were surprised, he was thankful that he had been surrounded by people that loved him instead of the alternative. Aziraphale had helped them learn about their birth family and Crowley decided to adapt his name to honor them.

Standing from his spot on the couch, Aziraphale made his way over to Crowley and with a gentle hand moved one of his curls out of their face and behind their ear. The blush that spread across the omega’s face filled Aziraphale with warmth. “I swear you won’t be a spinster or anything like that. Now, hurry along. I know you don’t want to miss your party and all the treats they’ll have. You have all of your precautions on?”

Aziraphale couldn’t help but be overprotective of his precious brother. Although he hadn’t seen them as family in a very long time. He had harboured a secret yearning for Crowley once they became an adult. Their time away at university had done wonders for not over their personality, but they had also grown into their lanky body. Aziraphale had no choice but to finally see them as the omega they were. Many long nights had been spent with him fighting the urge to pounce and take Crowley for their own.

An annoyed sigh and a grumble from Crowley signaled that he had heard the question. “Yes, I have my scent patches on and the Bitter Bite spray on. No one will be licking or biting me tonight. I even have the knot condoms you make me take with me on dates and such.” Aziraphale nodded and handed Crowley his bag before heading back to the couch where his book waited for him. “I just don’t want you to be taken advantage of, I may be your alpha guardian but I want you to be able to choose who you take as your mate.”

A car honked, stopping the omega from whatever he was going to say. Bounding over and kissing the top of Aziraphale’s head before leaving, Crowley hurried out the door with no more than a shouted “Bye big brother!”. As soon as his brother was gone and not returning, Aziraphale unzipped his trousers and began to quickly fist his hard and throbbing cock. The tip had already begun to leak and the small glimpses he got of Crowley’s thighs and being called big brother were more than enough to bring him over the edge. He knew it wasn’t technically wrong for him to covet his younger brother as they weren’t really related, and upper society families usually mated off their children together still, but Aziraphale didn’t feel right touching himself without his brother’s knowledge.

It was a few hours later when Crowley returned home, announcing his presence to the house with a shout. Aziraphale left the kitchen after having turned the kettle on for a late night cuppa to greet them only to see that something was wrong. Crowley was taking off his heeled boots more aggressively than he normally would and Aziraphale could sense that the evening hadn’t gone the way the omega had wanted. Motioning for them to join him on the couch, the alpha opened his arms and Crowley climbed onto the couch and snuggled into his brother’s lap much like he had as a child.

“Stupid alphas…” Aziraphale removed their hat and stroked their curls to soothe the omega. “Apparently I have been marked as not mate material by my friends and society because I’m so independent. The alphas had been leading me on as a game to see which one could get the closest to me before backing out. Now I know why my dates never went to the courting stage…” Hearing all of this had Aziraphale seething with rage and it took everything within him to keep from finding all of the alphas and Crowley's peers to beat some sense into them.

“There is nothing wrong with you, you are the perfect omega and anyone would be lucky to have you as their mate.” Swallowing his anger, Aziraphale nuzzled Crowley’s cheeks with him and finally got a smile from his younger brother. It was a moment more of cuddling before the alpha felt Crowley beginning to grow restless in his lap, releasing them Aziraphale was confused when his brother didn’t leave but instead adjusted to straddle his lap. “You always know exactly how to make me feel better don’t you? You’ve been the perfect example of what I have wanted in an alpha since I was little and have compared all others to you.”

Crowley pulled off his scent patches and pressed his face into Aziraphale’s neck to scent them, breathing deep to take in the old book and bourbon scent there. The alpha went completely still, hands hovering above the omega’s back and afraid to touch or do anything that might make them uncomfortable. It was becoming clear though that Crowley was doing exactly what they wanted when they started to grind on one of Aziraphale’s thighs.

Licking up his brother’s neck, Crowley began to purr when the scent glands started to produce more oils showing that Aziraphale was more than interested in what was happening. It was the first step in the mating process and Crowley was apparently not wasting any time. “Crowley, wait… We’re brothers and…” The rest of the sentence was stopped by a crushing kiss against his lips and after a moment, Aziraphale wrapped his arms around Crowley again and held him closer. Lips softened against his and formed a smile as the alpha began to kiss back. It was everything that Aziraphale had hoped it would be and more.

Pulling apart with a string of saliva still connecting them, both were breathing heavily and flushed. One of Aziraphale’s hands had moved from Crowley’s back to one of his thighs and was playing with the fabric of the skirt there. “Aziraphale, we might have grown up brothers, but we aren’t related. I should have acted on my wants years ago, but I didn’t think you would think of me as anything other than your little brother. Feeling how hard you are beneath me, I have decided that I don’t want an alpha like you, I want you as my alpha.”

Crowley’s voice was more confident than Aziraphale had ever heard it and he knew that once the stubborn red head decided something it was useless to try and change their mind. Growling possessively, Aziraphale wrapped his arms beneath Crowley’s thighs and lifted them into his arms. Carrying him up the stairs to his den, he placed him in the middle of his messy blankets and right where his scent was strongest. “Tell me no right now if you don’t want this and I will stop.” Aziraphale spoke as he began to quickly undress, staring at his younger brother lying on his sheets still in his slutty witch dress from the party. Eyes hooded and hands gripping the fabric above his head, Crowley purred and spread his legs open a bit more and licked his lips to entice the alpha.

“Bite and bond me, Big Brother. I want to grow heavy with your pups, hnnnng I want your knot so bad.” The groan in Crowley’s voice and the taboo of being called brother while about to be fucked spurred Aziraphale on. Pressing their lips together in another passionate kiss, the alpha all but swallowed Crowley’s tongue while sliding a hand beneath their skirts and running his thumb over their clit in tandem with the kisses. Consuming the moans before moving his lips to lick and suck on the omega’s neck, Aziraphale was so worked up, that he didn’t even bother to stretch Crowley’s weeping cunt properly. Flipping his brother onto their stomach and using a fang to shred the corset ribbons of the back of the dress in able to have better access to their backside, Aziraphale didn’t waste anymore time before mounting Crowley and humping them before their cock began to catch on the slick folds of their swollen folds.

Crying out in need and frustration, Crowley tried to reach behind him to help Aziraphale’s cock find their mark, but his hands were grasped in one of the alpha’s own in order to stop them. Instincts were running high and there was no stopping the alpha now, especially with the thick scent of needy omega was in the air. Finally finding the opening and forcing his thick cock into Crowley’s tight heat, Aziraphale howled in success before rolling his hips to get as deep within as he could.

The thrusts were fast and rough but Crowley wouldn’t have had it any other way, there was no predictable rhythm which gave a bit of spontaneity to the act and had his clit rubbing against the sheets causing him to reach multiple orgasms and clenching around the cock within him. It wasn’t long before he could feel Aziraphale thicken within him and the bruising force of the knot attempting to make its way in. Crowley was thankful that omegas kept their minds while having sex and that alphas went a little wild with instincts, he couldn’t imagine what it might be like the other way around.

One more aggressively forced thrust and the knot was in and growing until it was locked, filling Crowley to almost bursting. It was so much larger than any of his toys, he could feel the drool sliding down his chin from the delicious stretch. The fangs that sank into the side of his neck had Crowley screaming “Brother!” through one final orgasm. Aziraphale bit down harder and shook his head to ensure the skin tore and scarred over. The sudden pressure within his cunt told Crowley that his alpha was filling him with cum.

Falling all but limp, Crowley relaxed against the bed and dozed off to the feeling of Aziraphale licking at the bite mark and rolling his hips with every new burst of cum that was currently filling the omega’s womb. A contented sigh and a hand in aziraphale’s hair, Crowley ran his fingers through the curls there until he sensed that his brother had finally returned to his right mind. Instincts calmed down enough for Aziraphale to shake his mind clear where he began to fuss over Crowley, much like he had while they were children.

“Oh Crowley, I’m sorry. I didn’t mean to be so rough with you.” More comforting licks and gentle hands ran over Crowley’s body before landing on the bruises now on his hips. Crowley hissed a little with how sensitive his skin was and his sore muscles, but he didn’t regret it. Placing one of his hands over Aziraphale’s on his hip, Crowley started to purr again. “Don’t be sorry, I loved it. In fact I can’t wait for your knot to go down so we can do that again. Who knew you had such a big cock, big brother.” Crowley teased by wiggling his hips which pulled at the knot still locked within him.

A loud groan from Aziraphale and another release of cum, Crowley couldn’t help but giggle. “You have no idea what it does to me when you call me that, I can feel my cock twitching even now at just the mention.” The alpha grumbled into the skin of Crowley’s upper back. The omega’s cunt clenched before releasing in another tease. “Oh I know exactly what it does to you. Although I don’t plan on sharing that information with anyone else. It will be our little secret.”
