_______________________________________
Being an omega was never part of your plans.
In fact, being anything other than an ordinary boy had always made you uncomfortable.
You found out your designation at sixteen—as if adolescence wasn’t already complicated enough. Your overprotective, methodical parents reacted like they’d just received a terminal diagnosis: panic, fear, doctors, appointments. In the end, they decided to keep that part of you hidden from the world. “It’ll be easier this way,” they said.
And maybe it was.
For years, you took that little white pill first thing in the morning. It erased your scent, blocked any trace of heat, turned your existence into something neutral. A beta. Invisible. Safe.
But everything comes at a price.
By the time you were twenty-two, your body was already showing signs of strain. Headaches, nausea, bouts of apathy… It was during an emergency appointment that you heard the doctor say:
“We’ll switch to a monthly injection. I promise it’ll work.”
It didn’t.
On your very first official mission as Leon’s field partner, you could already feel that something was wrong. Too much heat. Your heart racing. Weak legs.
You thought it was just nerves… until he ran past you, his scent hitting your nose like a punch to the gut.
Alpha.
Not just any alpha. That alpha.
His scent wrapped around you like a warm blanket on a cold night.
Woody, with a hint of citrus underneath… and you hated how badly you wanted more.
“Fucking lying doctor…”
Your chest rose and fell sharply. You gripped the fabric of your shirt over your heart, trying to mask the tension. Your eyes stayed locked on the back of Leon’s neck as he walked ahead, explaining the mission strategy.
You didn’t hear a single word.
Your mind was screaming something else:
I need him.
You kept walking, Leon in the lead—always alert, gun steady in his hands, glancing over his shoulder every now and then to make sure you were still following.
The heat and pain inside you were only getting worse with every passing second. You were burning.
You barely recognized yourself—so desperate for sex that even Leon’s deep, gravelly voice made you bite your lower lip just to keep a moan from slipping out.
All those years of suppressed heats were spilling over all at once…
And thank God Leon was still ahead of you, at a safe distance.
If he caught your scent, instinct could make him pin you to the ground and take you right then and there.
Part of you feared that might happen…
But the other part? Was praying for it.
You tried to focus. You really did.
But the heat inside your body was unbearable, as if you were melting from the inside out—a fever that started between your legs and spread like fire along your spine, your chest, your neck… everywhere.
Every step you took was its own kind of torture. The fabric of your pants rubbing against overly sensitive skin made you shiver, and even the contact of your shirt against your nipples sent a sharp chill through you.
Leon’s scent in the air was like some forbidden perfume. Woody, warm, with a faint trace of sweat—a smell that clung to your nose, made your mouth water, and pulled your mind into places you really shouldn’t be going right now.
You bit down hard on your lip, fighting the urge to moan again. But it escaped anyway—a low, muffled whimper that you quickly tried to mask with your breathing.
Thankfully, Leon didn’t seem to notice. He kept walking ahead, serious, focused, oblivious to the chaos building inside you.
Your skin felt like it was begging to be touched. Any touch. A brush of Leon’s arm, a graze of fingers, even an accidental shove—anything that could take the edge off this insane need that was growing by the minute.
You were trembling. Not from cold, but like someone feverish—like your body temperature had climbed so high it started to cause chills. And no matter how hard you tried to control it, your body was beginning to give in. Your legs slightly weak, your heart pounding fast, your breathing heavier by the second.
Not now… please, not now…
The thought came like a desperate plea.
But your heat had no intention of waiting.
Your knees weakened, and you suddenly stopped, placing a hand over your stomach. Your skin was hot, and you let out a pained moan as a sharp, burning ache tore through you—stronger than before.
You dropped to your knees with a low moan, pressing your palm against your belly. The heat was unbearable. Your entire body burned from the inside out, like it was about to explode.
You heard hurried footsteps.
“Hey!” Leon’s voice called, as he ran back toward you. “What happened?”
You tried to lift your head, but everything was spinning. Through your blurred vision, you could only make out his silhouette crouching right in front of you. His hand gripped your shoulder—firm—and in that instant, everything changed.
He smelled it.
The scent hit Leon’s nose like a wave of heat. His whole body tensed, eyes going wide, pupils dilating in an instinctive reflex. He drew back slightly, as if he’d been shocked.
“…You…” he muttered, staring at you with a mix of confusion and fury. “You’re an omega?”
You nodded, too weak to explain anything. Your skin glistened with sweat, your breath coming in ragged bursts, your body trembling with fever and want.
“I’m in heat…” you whispered, your voice breaking. “Please… I need help.”
You tried to touch him—a light, pleading touch—but Leon grabbed your wrists, pulling your hands away like they burned him.
“No!” he snarled, brows furrowed, jaw clenched tight. “I can’t. I… fuck…” He was breathing hard, fighting the scent, the primal pull building inside him. “I won’t be able to control myself.”
Your eyes locked onto his, silently begging, on the verge of tears.
“Please, Leon… just a little, just until it passes…”
“Shut up!” he snapped, still gripping your wrists hard. The tension in his muscles was obvious, like he was waging war with his own body. “You shouldn’t even be here! An omega isn’t made for this kind of mission!”
You shivered at his voice—so deep, so rough—laced with an animalistic edge you’d never heard before. His scent was getting stronger, heavier, and your body responded whether you wanted it to or not.
“The agency knows I can’t… that I lose control when…” He bit his tongue, holding something back. “How the hell did you trick them? Huh? How’d you pass yourself off as a beta so easily?”
The anger in his eyes burned—but it wasn’t just anger. It was hunger.
And you knew it.
“Leon, please… I need this, and I know you want it… i-it’s instinct…”
His jaw tightened even more now, but the look in his eyes began to shift—he was starting to look at you with want.
“I won’t be gentle.”
He said it as he yanked you to your feet in front of him, his scent stronger than ever, making your head spin.
“I don’t care,” you said, already completely surrendered to him.
Before you could react, he was pulling you by the hand into a more secluded part of the forest, shielded by trees and bushes.
He began undoing his belt and unzipping his pants, removing his thigh holster.
The bulge in his pants was already impossible to miss—big, straining against the limits of the tactical fabric—and then, he pulled it out.
Fuck.
It was huge. Way bigger than you’d imagined. You knew alphas tended to be well-endowed, but you hadn’t known it could be that big.
Easily ten and a half inches—maybe more.
“Take off your pants. We can’t waste time!”
He spoke as he stepped closer, pulling the backpack from your shoulders. His voice was rougher now, and he kept wetting his lips with his tongue, like he could taste your scent in the air. His blue eyes were almost entirely black, swallowed by blown pupils.
You stripped as fast as you could, fingers trembling, your body sweating both hot and cold at once. Your scent was overpowering now—thick, sweet—filling every breath between you. There was no pretending you still had control. You didn’t.
Leon moved in, pressing his body to yours. His erection ground against your stomach, hot, throbbing against you. He let out a low growl—almost animal—like a predator about to strike.
“You sure about this?” he asked, but there was no hesitation left in his voice—only a warning. “Because I’m not stopping halfway, you got it?”
“Yes,” you answered without even thinking. “Do it… please…”
He gripped your chin firmly, forcing you to look at him.
“Say it again,” he demanded. “Say you want me. That you need me.”
“I want you, Leon… I need you inside me, right now…” Your voice came out broken, almost a sob.
Leon let out a rough, guttural sound and turned you around with firm, impatient hands. Your knees sank into the damp earth, bushes scratching at your bare skin, but you didn’t care. All you wanted was him.
He spit on his hand and quickly rubbed it over your tight asshole, just to ease the way, then positioned the tip of his cock at your entrance. You could feel it pulsing—hot, thick... and way too big.
“Relax,” he said, gripping your hips hard. “Or you’re gonna tear.”
You tried to take a deep breath, but his scent... his scent was intoxicating.
Then he pushed.
Slow at first, feeling every inch of you stretch around him until you let out a loud, almost desperate moan.
“Fuck…” he growled through clenched teeth. “You’re so tight... this is crazy…”
You dug your fingers into the ground, trembling all over, your body completely surrendered.
The heat-driven pleasure mixed with pain—the feeling of being truly filled, like you were born for this.
He pushed deeper and seemed like he’d never reach the end. In any other situation, this would probably be fucked up as hell. And it really was—but this pain was so delicious, burning in just the right amount.
He finally hit the bottom, and without warning, pulled almost all the way out before thrusting back in with brutal force, letting out a guttural groan.
“Aaah, fuck! Shit!”
He growled, speeding up his thrusts, his balls slapping against your ass with an obscene sound.
Little by little, that heat’s pain faded—the sharp itch inside finally soothed by an alpha male.
Your eyes rolled back in pleasure, and your fingers clenched tightly into the damp earth. Your hard cock was dripping pre-cum.
You caught a sharp scent—like rust.
Blood.
Your blood, probably running down your thighs by now.
Not surprising, given the intensity of the thrusts and the size of Leon’s cock.
He wasn’t holding you in the usual way around your waist. He was gripping you from behind, hard.
Your body was wrapped in those big biceps.
His sweat dripped and ran over you, marking you with his primal scent—a strong, testosterone-heavy smell hanging in the air.
Suddenly, with a firm movement, he flipped you over, making you lie on your back on the earthy ground.
He kept pounding deeper and harder, gripping your neck firmly to keep your eyes locked with his.
“Good… good boy.”
“You were made for this.”
“If I’d known you were a damn omega, I’d have fucked you a long time ago.”
Then he leaned in and sealed his lips on yours in a wet, fierce kiss.
You could taste the whiskey he’d had before the mission.
“I want to see you.”
And with that, he tore your shirt in half, exposing your abdomen and chest. He left a wet kiss there.
He squinted his eyes, gripped your waist hard, and kept thrusting brutally, his cock hitting your abused prostate dead-on.
“Fuck… look at this…”
He slowed down and placed the tips of his fingers on the lower part of your belly.
You looked down and saw a slight bulge forming with every movement he made…
His cock was going so deep it was touching the bottom of your stomach.
Fifteen long minutes passed, and you were a wreck—legs weak, abdomen covered in pre-cum, hair messy, and a layer of sweat beneath your skin mixing with the sweat dripping from Leon.
Leon gave three final brutal thrusts, then buried himself up to the wrist. He growled and pulled you close, then his cock began squirting thick jets of cum deep inside you… His cock kept pulsing nonstop… more than ten heavy shots filling you, your anal cavity stretching from the sheer amount of cum inside.
And then…
He marked you.
He simply brought his mouth to your neck and bit down, his teeth sinking into your skin.
There was no way out now.
You were his.
“I came inside… you’re going to have my babies now…” he said, pulling back to look into your eyes. His pupils returned to normal now, the blue of his eyes reappearing.
“I’m going to take care of you… because now you’re mine.”
He said, planting a light kiss on your forehead, still with lips and teeth stained with your blood.
“And I’m going to be yours too,” he finished.
