On any given day, Sherlock might come out of the bathroom smelling like an Alpha on the hunt (Alpha #8) or an Omega in heat (Omega #9), a Beta brooding (Beta #3), or like no gender at all. The last one was his actual scent, which wasn't so much scentless as confusing. At least in an adult. If Sherlock and John were the sort of people to read Mills and Boon novels, they could have said that what occurred was because destiny intervened and set two destined lovers in their one true pairings' path. It was the lasagna.

Tony Stark; genius, millionaire, awkward virginal alpha, and reclusive CEO of Stark industries. Steve Rogers, reporter for the New York Times, omega, and one of the single most domineering men Tony has ever met. He shouldn't want this, shouldn't like the things Steve offers, but he's never really been one for following the rules, now has he?

In a world where Omegas far outnumber Alphas, a dowry system is in place. The Omega’s family offers a dowry in order to secure a respectable Alpha match, with the highest dowries netting the “best” Alphas. Aunt May struggles to secure an Alpha for her Omega nephew’s first heat. All her meager savings can afford is a butt-ugly (by his own admission) Alpha without much experience to speak of. Peter would rather go unmated than lose his virginity to a guy that can’t go five seconds without making a Monty Python reference. However, it seems Peter has no choice…

Being away from Earth means going without heat suppressants. This proves to be a problem for Lance who has been avoiding his heats since puberty. Lucky for him Shiro and Keith are willing to help. “I thought that was why you were being such a jerk.” Keith’s feet shuffled over over the carpet. “You know. Another omega in your space?” “No, I just really find you annoying.”

Keith stood under the hot spray of the shower head, his eyes closed as he focused inward, trying desperately to regain some sense of composure. He wasn’t quite certain what was wrong with him today; he was the one moving out of sync in their training exercises, he’d run himself into an invisible maze-wall so hard he was dizzy for a quarter hour after it, and he swore he could still feel the static jolt under his skin. When Shiro had touched his shoulder, eyes concerned, his touch was like a fresh electric current and Keith had yanked himself away.

Just because an alpha can go through rut alone doesn't mean he should. "Okay." Lance's palms were sweaty with what he was about to say. He was about to break so many rules. "Cards on the table, guys. We got any omegas sitting here?"

Midoriya and Todoroki get hit by a quirk that triggers heats and ruts. In the 48hrs that follow, the secret that Midoriya has kept hidden is painfully revealed. Both Todoroki and Iida must find a way to keep him safe without hurting him further...and they'll need Bakugo's help.

Armin, an Omega, has been raised all his life to be a consort. An Untouched, deprived of physical contact, he is desperate for an Alpha to choose him as their own. When he's brought to the palace to be the only consort of the crown prince, he thinks his life is perfect. But there are dark secrets buried beneath his Alpha's kind exterior, and when they begin to reveal themselves Armin's idyllic new existence is shattered.

Sequel to '48hr Love Song.' In 48 hours things changed forever. Now Tenya finds himself on the road to an exciting future . . . if he can get past the maze of family politics threatening to trip him up. Things aren't easy when you carry a legacy like his, and your loves both have shadowed pasts choked with secrets. As for Ochako, she suddenly finds the road she's been on is actually a dead end. Lost and unsure of herself, she has to find a new direction to move in. Edit: Please notice updated tags

Obviously this was all the fault of Katsuki's perv classmate and his aerosolized heat trigger. Once Katsuki gets his life back under control, everyone will forget all about this moment of weakness. Nothing will change. He won't let it change. After all, he's going to be the number one hero one day. Just because omegas never go pro, that doesn't mean it isn't possible, right? ...right?

Kirishima tries to help Bakugou out during his first heat, and things get complicated.

Sawada Tsunayoshi is born an Omega in a world that expects nothing from his dynamic except submission. Tsuna is many things – hopeless klutz, booksmart-deficient, heir to a bloodline some people would like to keep secret – but, as it turns out, ‘submissive’ is not one of them.

Once the scent came to his nose, Oberyn had to pursue it. He had to find the source.

Sawada Tsunayoshi is born an Omega in a world that expects nothing from his dynamic except submission. Tsuna is many things – hopeless klutz, booksmart-deficient, heir to a bloodline some people would like to keep secret – but, as it turns out, ‘submissive’ is not one of them.

Tsuna learned young that he was not his parents priority. So he never said anything about the itch under his skin, about the way he sometimes felt his body burn from the inside or how the only time he felt calm was when blood ran like rivulets down his skin. [Or the one where Tsuna finds a family for himself and subsequently starts taking over the world (by accident)]

“Who are you?” Graves demanded hoarsely. “I’m Newt. Scamander. Err. Pleased to meet you. I mean, I would’ve been pleased to meet you, under normal circumstances.” “Scamander.” Graves frowned to himself. For someone who was supposedly in a bad rut, he seemed perfectly in control. “Your accent, it’s British. Any relation to Theseus Scamander? Head of the DMLE?” “I’m his younger brother.” “Are you an Auror?” “No. I’m a magizoologist.” Graves exhaled, exasperated. “A what? Is this a rescue or are you a hostage?” “Sort of neither,” Newt admitted.

It's involuntary the way his knees seem to buckle and give out and throw him onto the ground. It takes him a moment to realize he's hyperventilating, tears running frustratingly down his cheeks as he rubs his clothed erection slowly against the carpet. / Or the one where Bakugou Katsuki is presenting as a fucking omega, and there's nothing he can do to stop it

Stannis Baratheon flowers as an omega after the end of Storm End's siege, what will it mean for Westeros?

Lan Wangji is alot of things. He is intelligent, well-mannered, loyal and unfortunately an omega.

Meng Yao goes into heat while working as Sect Leader Nie’s assistant. Nie Mingjue shares his heat and Meng Yao ends up pregnant. Both believing the other regrets what happened, they end up in a marriage of convenience with all the misunderstandings and lack of proper communication to follow. Then Lan Xichen arrives in the Unclean Realm at the end of Meng Yao’s pregnancy and things get even more complicated.

Was there such a thing as an A/B/O novel that didn't end on an omega being mated by their one true love, their fated partner? That fucking Airplane towards the sky! Couldn't even get the genre he was writing in correct! Yet that was the mystery that had kept Shen Yuan reading! When would Liu Mingyan and the protagonist bone down? Even after they'd had their first five children and the harem had hit the triple digits, Shen Yuan had kept reading lured on by Airplane's glimmers of plot, backstory and writing ability slightly above that of a concussed toddler. ------------------------- “Of course I couldn’t make Mobei Jun an alpha,” said Shang Qinghua, having the fucking nerve to look pityingly on his best reviewer. “Bro, would three hundred million words have been enough to protect their chrysanthemums from each other in the fanfic forums? I just never mentioned it so it never came up so I never had to decide it. Problem solved.”

Proud Immortal Demon Way's fanfic selection is vast, terrible, and filled with things much worse written than the original work itself, and that's saying something. Shen Yuan was just enough of a masochist to willingly, after another stupid update where Luo Binghe has to papapa another sister for some ludicrous reason that doesn't even make any sense, decide to delve into that lurid cesspool of creative death and unbeta'd pornography far more explicit than anything Airplane Shooting Towards the Sky had ever written. Which is how he finds himself in a fanfic called Proud Immortal Demon's Milky Way.

That night he lies in bed alone until the moon is high. When the rest of the house is deathly silent, except for the light snores coming from behind every door, he sneaks in slippered feet through the halls and over to the covered kitchens. There’s faint light coming from the smoldering hearth, where the coals are piled to keep them warm for tomorrow’s early start. Someone has curled up by it on a mat, like a scullery maid. But it’s not a maid, it’s a man. A tall long-legged man. His husband. The dubiously immortal master of Changming manor. What the fuck, Xie thinks.

"Hi, I'm Wei Wuxian. I'm a Career Omega and this is my fourth season on the show. I like spicy food, archery and alphas who are funny. Or maybe I don't, I haven't rolled over for one yet." On-screen, Wei Wuxian winks at the audience laughter. Hot or Knot is the world's most popular reality TV show. Part dating show, part survival show, Hot or Knot is everyone's guilty pleasure - and Wei Wuxian is a fan favourite. - The Love Island/Hunger Games reality dating tv show A/B/O au

In which the five members of OG struggle to deal with A/B/O related bullshit before TI8, and celebrate after their win. Lots and lots of platonic cuddling and comfort ensues.

Beau has a good feeling about this season.

Sid has had a lot of strange meetings as the captain of the Penguins but this is by far the strangest. “You want to me to do what?” Sid asks, hoping he’d misheard Mike. ***** Sidney Crosby goes off his suppressants for a chance at the Stanley Cup and love.

It was hot, and Sid felt kind of weird about thinking it was hot. This guy was screwing himself on camera for money. That wasn’t really Sid’s scene. He closed the browser window. Fine for other people, but not his thing.

"The lawyers have found a pretty good loophole," Pat said. "It's not a loophole, it's a long-standing cultural tradition," Mario said, glancing at Sidney. "It's a fucking loophole," Pat reiterated. "But it's a great one."

"My friends call me Nicke," Backström—no, Nickie—finally said. His voice was very quiet, and Sasha found himself automatically leaning in to catch it, lowering his own volume to match. "Okay, Nickie!" he whisper-yelled, grinning widely. "I like this! Nickie is good nickname, hah, nickname, get it, Nickie?" Nickie clearly got it, but he didn't deign to laugh, or even smile. Sasha vowed to be funnier, the next time he tried to make a joke.

“I love being an omega,” Mitch says. He’s trying to stick his hair up into soapy spikes as Auston watches him tiredly from the other end of the bathtub. “I don’t have to do things I don’t wanna do and people take care of me. What’s not to like?” He pauses. “Plus, heats are sick.” “Really?” Auston asks, mind racing. Maybe it’s not too surprising. Mitch adores being taken care of, likes being babied and coddled; given gifts and affection. Marty got him a four foot stuffed bear from the cinema arcade a few weeks ago and his whole face lit up when he received it. "You like heat?" “Yeah,” Mitch says, and pats all his hair down before wading through the water, bending over Auston and bumping their noses together. He's smiling all sweet but Auston still feels like prey. “I really like it. You just lie there and take it and it feels so good ‘cause your body wants it so bad.”

Jack Eichel: Omega, and pissed off about it.

It's Jason's first heat after coming back into the fold of the Bat Pack and predictably no one else is around when he needs them. No one but Tim.

Not long after his confrontation with Bruce and the Joker, Jason crosses paths with an angry Poison Ivy. She accidentally triggers his heat before leaving him for Robin to find. Still scared and angry about the incident at Titans Tower, Tim has no choice but to help Jason work through his heat when it turns out that he's been abusing suppressants and could very well die without an alpha to help.

“We need you to Claim Tim.” Jason’s shirt falls to the floor as he turns around to stare at the acrobat, “What the fuck.” “Yeah.” Dick runs a hand through his hair with a manic giggle. “That’s fair.”

An uncomfortable family supper takes a turn for the worse after a secret is exposed. The King believes a hasty marriage can hold the family together, but how can that sustain peace when one of the grooms hates the other? “When were you going to announce that your second son is an omega?”

"The game is over, Uncle," Jace spoke calmly as Aegon froze in Arryk's hold. "I'm bringing you back home." Aegon fought back against fear and rage both, the emotions tightening his throat. "Y-You don't have to do this nephew," he pleaded, and he couldn't even bring himself to hate how weak he sounded. He didn't care. All that mattered was that he escaped. "Just let me go! You can find another to marry, someone more suited, I-I'm not-I wouldn't begrudge you! Please, just tell them I'm dead, or that you couldn't find me, Rhaenyra didn't even truly want this..." Jacaerys' steely features softened and he walked forward to where Aegon was still held by Sers Arryk and Erryk. "Why should I search for another when you are right in front of me?" Jace reached out to hold his uncle's chin, "and you have a duty to fulfill." Aegon attempted to look away but the king tilted his head up, forcing him to meet his dark gaze. "I want an heir."

“You must never reject an alpha’s advances, or they will force them. Or direct them elsewhere and sully your name with whores and bastards,” Alicent explains to him, in the days following Aemond’s first heat at the age of 12. Explaining his added duties, his unexpected new place in society. “After enough times an alpha may let you prepare with oil. But at first you must endure the mating bite, and then the pain of every encounter after.” Or: The world teaches Aemond what it means to be an omega. And then, with much time and healing, his new husband helps him unlearn it.

Despite literal years of Zeff badgering Sanji and trying to get him to give up being the sous-chef at the Baratie and go on his own adventures already, Sanji refuses. He owes Zeff his life, his past and future, everything he can give the old man—he's not leaving. His occasional excursions elsewhere and back are just temporary ('internships,' Zeff calls them), and he always eventually returns home. This time Sanji visits Tottoland, excited to learn from the culinary envy of the world, but he encounters a lot more trouble there than he expects in Charlotte Katakuri.

Sanji will just go knock. Appease his own sense of responsibility, get yelled off, and come back to his own bed knowing he tried. It’s the least he owes the frustrating marimo, as crewmates; to at least make sure he’s got options.

Meonji

“They had been told, as young witchers, that the burden of their secondary sex had been relieved by the Trial of Grasses. The mutations took away the change that would come as humans hit adulthood, and they would be without a subsex. Witchers were men, and men alone. They were not given the added burden of being an alpha, or an omega, or a beta. They were free from that particular form of madness.“ Jaskier is hired to be a heat companion for an omega widow, and Geralt is hired alongside him to play bodyguard. Unfortunately, being so close to the chaos that is human mating cycles, Geralt begins to suffer strange symptoms of his own. Trust Jaskier to take care of it. He’s a professional, after all.

Usually when Dean films a gangbang, it's all alphas from top (everyone else) to bottom (him). Today's shoot involves a second bottom, a popular omega with a pretty face and absolutely no acting skills. They don't exactly hit it off... right up until they absolutely do.

After everything Jason did, can Tim actually want Jason as his mate? Is that even in the realm of possibility?

“I want you to bitch me.” Tim reacted to the word so strongly he nearly fell off his chair. “Kon you- you can't say that!” It wasn't a word one should bring up in polite company, Tim had learned early on. Kon rolled his eyes emphatically. “Fine. I want you to help me transition my dynamic into one that more closely resembles how I feel inside. Happy?”

Jason Todd wouldn’t admit it, but he wanted to go home.
