The classroom… The one place I felt most safe... WAS the one place I felt most safe and in control, that is, until the day Bakugou Katsuki walked through the threshold and upended my entire existence.

As a teacher I pride myself on being thoroughly professional in all aspects. I oversee everything from all angles and… am very straight-laced to say the least. I, Midoriya Izuku, am thirty-one years old. Have been a teacher since I was twenty-four. Have trained, inspired, and influenced hundreds of students that have passed through my classroom… I am professorial, controlled. I take my job seriously, and I am… I… am… thoroughly fucked. And by a fifteen year old none-the-less… I am the epitome of pathetic!

At first, I didn't realize just how fucked I was. When he first walked in, I'd be lying if I didn't say he caught my eye. Not in a sexual manner! He's different. From a purely professional standpoint, I could tell he was a problem child. He had a sneer etched on his features for the better part of the first ten or-so minutes of my class when I was introducing myself, course, and syllabus. He never made eye contact, just merely rested his cheek on the heel of his hand. Like he was bored of the world, and... that intrigued me.

Considering my non-existent love-life, I never thought I would have any sexual response to anyone. Don't get me wrong, I've had sex, but every encounter just seemed...empty. I had come to the conclusion that there just wasn't anyone for me, and that I should focus primarily on academics. So, I did.

Everyone else always seemed infatuated with finding a mate though, and I could never understand. Living in a world based on secondary gender roles, I felt as if I was a defective alpha. No one scent was enticing to me, ever, despite how others tried to trigger my inner beast. I honestly believed that that didn't exist, because there was no evidence to support that it actually DID exist. It was as if I were a beta, I assumed, or maybe the blood test was wrong...thrice. I didn't know. I didn't understand, that there was this whole other world where my every sense could be on high alert with a slight whiff of that scent.

What I mean by on high alert, is that I could be aware of everything that person is doing and feeling...with just a trace of scent. Mind-blowing. I was not prepared to deal with this in any cognitive way whatsoever. Entire focus zeroed in on that one person whose scent wafted my way...what? What was I saying? I don't know, because holy hell does that spicy musk smell...sigh...like my own personal God has arrived to fuck my world to bits...until nothing is left.

I pride myself on my self-control, and thus have done nothing. Will...do nothing. Will not pursue. He is a child. He is innocent. Except, he just presented...as an omega...in my classroom!

It started slowly, the smell, over the past few weeks. Seemed no one noticed except me. Realization didn't dawn on me until now, but going over my memories I should have realized sooner. Although, this is all very shockingly new to me, as I didn't believe it to actually be real... I thought it was impossible! That the sudden infatuation growing inside was just me going insane...or that I needed a vacation…

"Damn, baku-bro," Kirishima waved his hand in front of his face, "did you forget to wear deodorant?"

Deodorant? My brow furrowed, does that intoxicating scent smell bad to others?

"Che...your fucking nose must be broken."

The normal teen could present anywhere from ages fourteen to eighteen, with the majority presenting at age sixteen. So, the majority of the class hasn't presented yet…could explain the 'bad' smell.

I could barely inhale with that alluring scent permeating the room. It felt so thick I could taste him. My judgement was clouding as I felt stirring in my gut. Cheeks flushing. Not good.

"I smell it too Bakugou." Uraraka's tone was concerned, "I think you should go to the nurses office."

"Hah? Why?"

"You look flushed…"

His cheeks were pink. It almost made him look...cute. Faintly I wondered if his body was unconsciously responding to mine…though I knew I had scent blockers on as required of all faculty. I bit my lip and stood from my desk.

"Bakugou, she's right." I cleared my throat. My voice sounded foreign even to my own ears, "You don't look so well. You should go to the nurses office."

He looked as if he was about to protest, but then winced almost doubling over his desk. Before I knew what I was doing, he was in my arms. How I traversed half the classroom in mere seconds, I'll never know.

"Uraraka, you're in charge. Just continue your assignments."

Throwing his arm across my shoulders I pulled him from his desk and walked him out of the classroom. He was much lighter than I had expected, and he even felt small in my grasp. I felt that he wanted to protest how he was being treated, but his free hand gripped his stomach while he clenched his teeth against the pain. I knew from a/b/o physiology that the first heat was always the most painful.

Breathing through my mouth to keep from smelling only lead to tasting. Not sure which was worse. His spicy musk was clinging to me through the bodily contact. Could feel it seeping into my skin.

Broken, incomplete thoughts. Not good.

"Midoriya-sensei…"

I couldn't respond. Rock hard and weeping...leaking precum. Inhaling through my nose, a sweet smell accompanied the spicy musk. Slick. I burned. I kept moving with my ward to the nurses office honestly shocked that this was even happening.

"Shitty-sensei…"

I could feel my skin suddenly become clammy from sweat. My eyes widened, if I was sweating there was a good chance the scent blockers could…

"We're going the wrong way!"

Snapping out of my thoughts, I looked around to see that indeed, we were going the wrong way. Looking at Bakugou was a mistake. He looked fuckable. I felt the urge to turn him upside-down and taste that sweet slick. Trace each pleat of his asshole with my tongue before tongue fucking that virgin hole. Make him scream in ecstasy until…

"Don't...look at me like that!"

My eyes widened and I nearly dropped him, "I'm sorry!" In an effort to not drop him, I pulled him closer. His heavy breaths washed over the sensitive skin of my neck and I was nearly undone. I imagined all possible outcomes, all positions, how I'd force my cock into him… This wasn't me! Is this what it's like to be overcome by the beast within? The urge to mate, to bite, had me salivating!

Bakugou shifted in my arms, groaned, and nuzzled into the scent glands at my neck. I stiffened.

"Shitty-sensei…" He murmured breathilly, "smell good…"

Had to get him to the nurses office!

Jerking awake I woke with a start. It was just a dream! I wiped the sweat from my brow as my shoulders slumped. This is insane. My reality is all distorted, so warped I no longer can tell if I'm actually awake or dreaming. Trying to slow my breathing I notice the tent in the sheets. FML.

Bakugou Katsuki hasn't actually presented yet, but I have a feeling he's going to be an omega. Why do I have this feeling? Maybe because I've never had a feeling like this before in my life, and if the wet dreams were any indication...it's a very strong feeling.

Very strong feeling, I think as I palm my engorged alphan cock. I've never had much of a need to relieve sexual tension, but this has increased ten-fold upon meeting one Bakugou Katsuki. Which was just a mild inclination at first has transformed into full blown obsession. It's as if I can't help myself...it just...escalated…

Blonde hair… Crimson eyes… taut body… round ass… I could just imagine him presenting for me. Ass up, looking up at me over his shoulder. His hands would find their way to his cheeks and he would spread them for me. My breath would catch at witnessing such perfection, and my heart would ache.

I would cum in my pants if that would ever happen.

Squeezing my cockhead at the thought of penetrating that tight heat, I'm nearly there. I'd slide in slow, open him up. Would he grunt or gasp? A mixture of both?

Squeezing the base I work my way back up and fuck my hand slowly, just as I would fuck him. I want to cum inside him, paint his walls white with my essence. And, yes, I realize just how fucked up I am, but I'm too far gone at this point.

I'd speed up, fuck him faster and faster until he's fucking screaming and begging to cum, to be claimed, to be mine.

Biting my wrist to keep from crying out loud, I cum hard.

Releasing a shuddering breath I relax, give a couple lazy strokes and release my grip. I run my clean hand through my tousled hair, tangled from thrashing around while sleeping, and passionate self gratification...I sigh.

He's going to present soon. Each day is maddeningly worse than the next...and I have no idea what will happen when it does. When it does...it's going to be hard to accept, I know that much. But what I'll do… I know what I want to do. I want to knot him. Is that socially acceptable? No, and even less so since I am his teacher. The biology of it doesn't account for things like this. Nature's rules often don't coincide with man's rules, and every fiber of my being is screaming to claim this boy.

That sounds like a news story… "Alpha couldn't keep it in his pants, raped fifteen year old."

It's fucking instinctual! I didn't ask to be this way! I was perfectly content with my boring lonely life. Ok, not perfectly content, but mostly. And I never would have known what I had been missing if I never met Kaachan.

Yes. I gave him a pet name. One that he will never know about. That is unless he ever shows interest...which he can't! He won't. Then again, there's only one way to find out... Forego the scent blockers, and claim I forgot...perfect. It...it's just an experiment...just to see if all this instinctual stuff is all in my head. To prove that I'm not crazy...or to prove that I am, and that I need to seek help.

Massaging my temples I realize I already need help...but I cannot tell a soul.

I'm aroused again at the thought of what sort of reaction Kaachan will... would have. Would. If I ever...which I won't...go without scent blockers. Would it trigger his heat? Ugh...I'm dreaming...it'll never happen.

Normally students wear scent blockers after they present, so after Kaachan presents...I won't have to be tortured anymore. That's a sad thought. Despite being tortured by that scent...it suddenly disappearing is depressing.

Throwing an arm over my closed eyes, I sigh heavily. I don't understand any of this, but I wish I did. Google. I search for my phone in the dark on the bedside table. Palming it I unlock it and tap the internet icon. Tap the search bar, and the keyboard appears. I hesitate, and bite my lower lip. This will be on my search history...should I even attempt a search like this? Could it later be used as evidence? Not if it's benign... like a/b/o physiology...

Hesitantly I type "Alpha/omega physiology" and tap search. What I'd love to search is Alphas and unpresented omegas...but feel that would just lead to porn...or worse. So, searching through information that I already know, I stumble upon a gem that reaffirms everything that I believe.

The strength of the match is determined by scent. In that scent an alpha or omega will know exactly how compatible they are with the opposite based on the pull of said scent. Much like a magnet, if compatibility is high, it will be very difficult to resist the pull of the other with the insistence of nature's urge to procreate.

Just as magnets, low compatibility matches will often not affect the other or in most cases repel the other with an offending scent.

In extremely rare cases, children have been able to scent a high compatibility match amongst their peers before either have presented, and are said to be 'fated mates'.

Fated mates…maybe.

Unmated alphas aged over twenty-eight may experience a coming of season. In which their alphan instincts kick into overdrive when a high compatibility match is scented and the urge to mate becomes undeniable. Over time, senses will heighten ten times more than normal, and what was once tolerable will become overbearing often interfering with normal everyday life. If left unchecked, their reality will be skewed to the point the only thing they can think of is mating the omega. This is one of the many ways nature preserves the species…

Shit…

If the omega match were to go into heat, instincts would completely take over. There would be no reasoning, no thought process other than the urge to mate. Exercise extreme caution around an alpha that may be perceived to be experiencing a coming of season. If threatened, the alpha will become extremely aggressive…

Holy...shit.
