The worst thing about being an omega is heats.

They can take anywhere from three months to a year for a cycle to complete. Meaning nine months is spent in constant suspense and hesitancy. They have to be careful; going into heat at the wrong time and the wrong place is a recipe for disaster, turning pleasant alphas into bloodthirsty warriors desperate to win the right to mate the unlucky omega.

Mated Alpha's, Omegas, and most Beta's are safe to be around. As mated pairs are immune to other scents except their chosen partner, Beta's aren't usually affected by the pheromones, and Omega's can naturally resist the scents of others.

Most people are Betas, about thirteen out of twenty. Six out of twenty are alphas, leaving omegas a rare occurrence.

Only one out of twenty people are omegas.

It's one of the reasons Asami had never told anyone she was an omega. Her cycles had always been regular, every six months she would spend her heat locked up in her pheromone-resistant chamber for four or five days; using work as an excuse for it.

They always believed her, and it's not like they could tell she was an omega by scent. She always wore a special perfume made specifically for covering up her identity.

It's why she often allowed herself life's little pleasantries, and often found herself able to stay on Air Temple Island with the others; especially with Harmonic Convergence passing just a week ago, and the vines blocked her way home.

She was confident in her timing. She was not due to go into heat for another two months, she had plenty of time.

But when she woke up that night, sweaty and sore, desperate for someone to ease the ache between her legs; she knew she had messed up.

She groaned and climbed off the bed; thinking for anyone she could go to for help. Pema had been the only other Omega she really knew. Maybe she had suppressants with her.

But she knew that was a bad idea.

Pema and Tenzin's room was in the main building. She would have to walk through three separate hallways to get there, and the acolytes' rooms where on the way. She couldn't risk alerting any of the alphas in the dormitories.

Asami bit back a pitiful whimper as she thought about the alphas. Her senses were screaming at her for one, to allow one of them to ravage her; more disturbing was the signature wetness she could feel between her thighs, making her slick enough to be knotted.

She shuddered at the thought; she'd never had sex before, never really had the time for it. She had been so busy with Future Industries, the thought of dating again was the furthest thing from her mind.

That meant if she taken, it would be her first, and most likely it would be painful as well.

Her heart hammered in her head, and she stumbled to the small bathroom connected to the room. Once she reached the sink, she turned the faucet on and cupped her hands for water; she splashed the water over her face, enjoying the cooling sensation the chilled water had on her flushed skin.

It was becoming unbearably hot; her temperature climbing as her heat furthered along, coming into full swing. Asami exited the bathroom and made for her purse on the bedside table.

She needed her perfume, it would cover the scent, at least well enough to make it where she would be able to sneak past the sleeping acolytes and reach Pema; there wasn't any alphas near her guest room, so she should be safe-

That's when the door slide open, and a challenging growl echoed behind her; her hair stood on ends, a chill swept up her spine as a pulsing ache made itself known between her thighs.

Spirits, her body was excited by the growl.

Asami let out a shuddering breath. She knew that voice, she knew it.

"Korra?"

She got a pained grunt in reply; she still didn't trust herself to turn around, the slightest movement could set the avatar off.

The heiress gasped when she felt a warm body press against her back, a pair of lips pressed against the pulse point of her neck as another growl vibrated across her skin, "Asami. Don't. Move."

The avatar's hands were everywhere, leaving a burning trail down her exposed arms.

She was wearing one of her silky nightgowns, but it didn't offer much protection from the alpha's advances.

"You feel so good," Korra moaned; her hips grinding against Asami's backside, holding the pale woman flush against her.

Asami whimpered miserably, the ache expanded and she was forced to bend over the bed; her body trying desperately to gain more of that delicious friction Korra's movements were causing.

That was enough to push the alpha over the edge, and Korra suddenly yanked at the others dress; pulling it up over her knees so that she could sneak a hand up the creamy thighs and brush against the silky material of her underwear as her fingers rubbed the omegas aching core.

Asami cried out, her back arching against the alpha pressed behind her as one arm wrapped around her waist to hold her in place and the other continued the attack between her thighs. Her legs felt so weak, she thought she might collapse onto the bed. Her moans were soft yet persistent, the face pressed into her neck let out a long groan as the others hips continued grinding into her.

"Korra," a breathless moan escaped her before she could stop it; her instincts were taking over her senses. She had the strongest alpha in the world trying to claim her, why couldn't she let her?

Even in heat she knew it was a bad idea, but she couldn't voice it. It felt too good to her, the fingers rubbing quick little circles on her clit.

She needed more, she needed to be taken. Her mind was foggy with want, her head leaning back against the others' as she panted shamelessly, "Please! Please!"

"You want it?" Korra's lips brushed against her ear; her voice was husky with lust, and her hips were still grinding against her in an intoxicating way, "Beg for it."

Asami had to bite down on her lip to keep from screaming when Korra's fingers slid under the fabric of her panties, moving through her slick core and effortlessly teasing the sensitive bundle of nerves that had the omega gasping and whimpering in ecstasy.

"I said," Korra's grip tightened around her waist, and Asami moaned as the Avatar growled into her ear; the fingers on her clit violently rubbing the throbbing button. "Beg. For. It."

"Please!" Asami cried. "Take me! Have me! Make me yours! Please, I'm begging you!" Asami arched against the water tribe girl sensually, "I need you!"

That's when she sealed her fate, and Korra flung her around; pushing the heiress onto her back and climbing over her body. The Avatar's hands made quick work of the nightgown covering the alpha's prize, pulling it over the inventors' head and off to the side of the room.

Asami shivered as the cool air brushed against her exposed body, but she quickly warmed up again as she watched the master of the four elements pull off her pants and sleep shirt; before leaning down to press their naked skin together.

Korra's eyes were dark with lust, and her scent filled Asami's mind. Her instincts told her it was time, that this alpha was the best specimen for her. She was ready for the dominant Avatar.

Her eyes fluttered closed as her lips were claimed by the others', a moan escaping her throat as the avatar pushed her tongue into the others' mouth; exploring the territory she craved to have.

Asami groaned and arched upwards; her bare chest brushing against the others' as she felt Korra grind their hips together.

By god, it felt so good. She gasped and moaned with every roll of the hips; the friction was addicting and dangerous, like she was playing with fire.

They moved against eachother, their hips grinding in such synchrony that both were left to throw their heads back as their movements became more frantic and unrestrained.

Asami let out a gasp when she felt it, her entrance clenched in anticipation as Korra's alpha physiology came into play, and the omega felt the avatar grow hard against her.

"Please," she murmured, her hands pulling the other down for a wanting kiss as she breathed against her lips. "I need you..."

"Where?" the avatar groaned, both of her hands coming down on either side of the omega writhing underneath her, "Tell me. Say. It."

Asami whimpered as she felt her panties being pulled down her long, smooth, legs. Korra had freed both of them of the rest of their clothes. There was nothing left to imagination, they were completely exposed.

The heiress gasped as Korra kissed her deeply, the southerner drinking up the moan that came from dragging the head of her member up and down the omega's aching core, "Tell me."

"Inside me," that was it for her, she was gone. Her heat had clouded her mind and out flew any common sense left in her brain. "I. Need. You. Inside. Me."

Korra groaned and nodded, spreading the others' legs and placing the head at her tight entrance. Asami steadied herself; her nails digging into the Avatar's shoulders as she felt the alpha's member sink into her. A burning pain caused her to cry out, tears flooding her eyes as Korra gently kissed them away. She managed to seat herself within the omega completely and came to a halt, giving the other time to adjust to her size and allow for the pain to pass.

Their bodies were pressed together so tightly, Korra's face hovered just inches above her own; something in the Avatars eyes began to clear, but Asami didn't have anytime to think about it before the native water bender started to move.

"You're so tight," Korra whispered appreciatively. "I'm your first." She stated it like a rhetorical question; she knew she was Asami's first, she had just taken her virginity. But, it was something she wasn't used too. She'd never slept with a virgin before.

Asami nodded as she panted with each thrust, "First."

Korra chuckled as she ran her lips up the skin of the inventors pale neck; her omega scent was filling her, drawing her into a trap she didn't want to escape, "It's an honor."

Asami moaned and arched her back, the thrusts were hitting every point inside of her. She felt like she was on fire, a blush dominated her face, one that went all the way down to her neck. She threw her head back against the pillows, her hands fisting into the sheets as her chest rose up and down with each breath.

Korra growled when she felt the other's legs wrap around her thighs, pulling her ever closer to the beautiful heiress. They were so completely lost in eachother, the avatar straining to reach the end of her journey, and explode within the whimpering omega underneath her.

"Korra," Asami's moans where like petals in the wind, so beautiful to witness, to see and hear. It lite an inferno inside of the bender, an inferno that left her desperate for release, for the satisfaction that came with pleasing an omega.

"Asami," Korra's pace became harder and faster; moving more like a wild animal. "Asami I'm going to cum."

"Me too," the inventor's hands went to the avatar's back; her fingers leaving raw scratches down her spine and across her shoulders. "Me too."

"Cum for me," Korra gasped in her ear. "Let me hear you scream my name."

"I..." Asami fought to catch her breath, the bed was creaking with their movements; the wind was the only witness to the primal mating taking place. Tension built in her stomach, like a rubber band being pulled farther and farther. Korra felt so good, so right. She could barely remember how to breathe.

Then she felt the thrusts' brushing against something inside her, and the band snapped.

A strangled scream tore out of her throat, and Asami found herself clinging to the avatar for dear life as she was pushed over the edge, "Korra!"

The master of the four elements snarled liked a feral animal, her orgasm crashing into her like a tsunami, and she collapsed onto the heiress as she felt herself expand within the other's warmth. Asami wiggled her hips as she felt the increase of pressure, prompting Korra to lean forward and use her weight to hold the woman still, "Don't move. I'm knotting."

Asami gulped and nodded her head; her legs were still wrapped around the other's waist, but she wasn't uncomfortable.

Korra relaxed and leaned back down on her, grinding her hips as she tested the grip her member had inside the other, "It should pass in an hour. Just try to relax until then."

"What happens if I...?" Asami swallowed nervously, "If I conceive?"

"Don't worry," Korra pressed a kiss to her temple. "Despite popular belief it takes constant knotting throughout one's heat to conceive. One time isn't that big of a chance."

"And if the odds aren't in our favor?"

Korra chuckled and kissed her gently, "We'll cross that bridge when we get to it."
