I hope you all enjoy, and expect a new chapter of my other fic soon :)

Warning: Sexy parts talk...

Korra wasn't one for ditching school, but when her body was this much in pain, it was well worth getting in a little trouble for leaving class. There was an unfamiliar itching like sensation around her abdominal area. She didn't have any literal itch down there, but it was as annoying as having one, if not worse. Something was pulsing between her legs, begging for attention. There was an unknown bulge in her skinny jeans. Of all the days, today was the day she'd have to deal with her alpha anatomy for the first time, and of course, she was wearing skinny jeans. Not only did her erection make itself very evident, but there was also an immense amount of displeasure because of the tight pants.

It all started in Calculus. There was tingling happening down there, but the Southerner payed no attention to it, not knowing the chaos that would happen a half hour later. The class ended shortly after the tingling sensation started, but nothing physically changed. Not until English class came, at least. A heavy pulsing started in her pants, then something extended out and up towards her belt line. It took about a full two minutes for it to finally settle as the large bulge it was. Having been incredibly visible to anyone looking in her general direction, Korra quickly ripped her navy blue hoodie off and placed it in a ball on her lap. No one seemed to notice or care at all, which was a relief to the stressed teenager.

Only being ten minutes into the class, Korra was getting more and more aroused. It was almost impossible for her to conceal her need to find the nearest omega and fuck them mindlessly. That's when she picked up an amazingly strong and irresistible scent that was lingering in the room. An omega had just started their heat.

Fuuuuuck, Korra thought as she inhaled a full breath of the sweet, alluring smell. How can something be so addicting? She stole another inhale of the omega's lingering scent. More of the tingling sensation in her crotch appeared, but also, it started to poor around her whole body, concentrating mainly in her gut. Her abdominal area was screaming at this point.

Returning to her conscious, aware, teenage self, Korra found herself in an unbearable amount of both pain and the longing for pleasure. She needed to get out before her so-called alpha instincts kicked in. If she happened to let her instincts settle her needs, her girlfriend would kill her, her parents would kill her, and the school board would for sure cancel her future, which would be the same as the school killing her. She needed to get out of this room.

Shooting her hand in the air, the Water Tribe girl requested to go to the bathroom, interrupting the middle of Mrs. Pema's lecture on rhetoric. Thank Raava she was in Mrs. Pema's class and not Mr. Zaheer's or Ms. Izumi's classes. Both teachers were increadibly strict, especially Mr. Zaheer. Well, Korra and he had never gotten along. From the first week of school until now, which was the beginning of the second semester, Mr. Zaheer showed great amounts of dislike towards Korra. She was barely making it through his class with a C+. A C+ in her favorite subject: history! Every student knew Korra as a good peer, always getting decent grades, but Mr. Zaheer saw something else in her. Maybe it was her sarcasm or that sass she hid away until she was either with her friends or at home. Korra had never figured out why that teacher hated her, and she would probably never find out why, means that she couldn't give a shit about him.

Leading back to Mrs. Pema's kindness, Korra was dismissed to go to the bathroom. The Southerner shot from her seat with much relief, while jamming something into her backpack as an excuse to keep the bag in front of her jeans. She skipped down the hallway, past a long line of lockers, to her locker. 64. Spinning the lock as fast as she could, she unlocked the door and shoved her huge history text book and calculus study guide in it. It was a relief not having to carry that extra five pounds around on her back.

After locking away her books, Korra crept to the gym, so she could make her way to the field. It was the best way out without being caught by a patrolling teacher during their break.

As she trotted through the halls, the pulsing in her crotch grew. The mound on her lower body shown visibly through her pants. Her backpack made her much more mobile on her back, so she threw it on. Her hoodie was easier to hold, having been riding down her legs with all the movement, so the erection was completely visible. The stressed alpha didn't care if anyone saw it; all she wanted was to get out of this raavadamn school away from everyone.

There was a buzz and a high pitched DING! that came from her backpack. SHIIIIIIT! Korra pulled her light blue and white pack in front of her as she still remained trotting at a steady pace down the high school halls. She glanced around to check if any teachers had caught onto the cellphone alert. Nobody. Thank Raava! At least my luck isn't as bad as I thought it was today. She let a small, smug grin appear on her face.

Once she had made it onto the track, Korra pulled her cracked, white phone from the small compartment of her bag to look at the message that had almost blown her cover.

Ope (heart emoji and kissy heart emoji x3) 4m ago: Want to go out for some dinner tonight after ur practice? Ill pick u up and bring u back then we can go get something.

Korra stopped in the middle of the field to reply.

Kor: I dunz know Ope. Today's been a really weird day for me and I'm skipping school and practice.

Ope (heart emoji and kissy heart emoji x3): Why didnt u just say u were skipping everything today? Ive been home all day. We couldve hung out

Kor: Look Ope it's been a very weird day and it's still weird. I don't think I can hang today

Kor: I just don't feel well that's all

Ope (heart emoji and kissy heart emoji x3): Awww u should def come over then! Ill help u feel better :) ;)

Kor: I don't know... I dunz think it's a good idea rn

Kor: Whatcha doing home today anyways?

Ope (heart emoji and kissy heart emoji x3): My heat came so I didnt want to throw anyone off at school. Also didnt have any suppressants today to cover my scent

Kor: Ohhhhh... yeah that's understandable. I don't think I should go over then...

Ope (heart emoji and kissy heart emoji x3): Why not? U will be fine wont u? Its never bothered u before.

Kor: Well that's the thing. Today I found out something about myself...

Ope (heart emoji and kissy heart emoji x3): OMG ur an alpha?!

Kor: Yeahhhh hah surprise!...

Korra bit her lip. Opal, her beloved, cute girlfriend, was probably freaking out. There was no reply for another few minutes, so Korra just assumed Opal was sitting on her bed, both shocked and excited about the news. Both of them hadn't known of Korra's true physiology until now.

Opal had found out she was an omega two years ago, a year before they hooked up. It was strange to find a supposed female beta dating a female omega, since omegas were usually more attracted to alphas. Now that explains everything... Korra thought.

She examined the still erected cock in her pants. All along she had been an alpha, but for some reason today was the day she'd find out. Through the couple of her girlfriend's heats she'd witness, the Southerner had been unaffected by them. But why today? What awakened her suddenly?

The thought clicked in her mind as soon as she took in a breath. The omega in heat in class today...

It was the only thing that could bring her to this level of arousal. Who was this omega, and why was she so tied to them instead of Opal?

Another thought popped into her head. Maybe if I visit Opal today, it'll feel the same or even better being around her. She's even in heat. I have to find out.

Kor: Hey Ope if you don't mind me coming over today I will. Right now actually since I'm almost off of school grounds.

Ope (heart emoji and kissy heart emoji x3): Sure! if u think its okay... I mean u can conceal it right?

Kor: yeah yeah I can. I have before so why is now any more different? I'll be there in about 15mins okay?

Ope (heart emoji and kissy heart emoji x3): OK! See u then babe :)

Korra skipped off into a steady paced jog towards the perimeter of the field and jumped the fence. The rebel then made her way around the back of the school and onto the streets of the neighborhood, strolling down the sidewalk in the direction of the Beifong mansion.

Little did they know, this was one of the most stupid things they could have done. An aroused alpha and an omega in heat did not mix well on the appropriate levels. Things were always going to become intimate with these kinds of combinations. Of course they didn't know any better, since they were stupid, ignorant teens living the life.
