-
‘Just finishing up here. I’ll be over within the hour. Wear that special dress I bought you. x’
You immediately feel a deep flush cover your face and neck as you read his text. You physically stop and take a deep breath, enjoying the heat that pools in your stomach a little too much.
It’s moments like this that confirm what you already knew after a single date with Kento Nanami; he was simply the man of your dreams.
Dating always felt like a chore until you agreed to a blind date with him, not knowing he would be perfect in every way. Strong, reliable, and an alpha.
Alpha.
Never in your life did you think you’d find one who wasn’t an overgrown frat boy. They always had too much attitude, too much ego, and it left a sour taste in your mouth after each date.
Then enters possibly the most perfect man you’ve ever met.
He was a gentleman first, always a gentleman. He took things slow, deliberate, and careful, which is exactly what you needed most days.
You beam just thinking about him, imagining your time together, how a perfect life is so close with the man you love.
And then it hits you.
Standing in your robes, you watch your demeanor change in the mirror, heat visibly coming off your skin and your vision becoming hazy. Everything looks softer now, and your muscles feel tighter.
It’s just the beginning.
Fuck.
You knew this feeling; only once did you ever let yourself go long enough without suppressants to feel this.
Just out of curiosity, and it kicked your ass.
You shouldn’t be this warm. This hot, prickly feeling just under your skin.
And there’s no time to panic, because Kento is at your front door before you know it.
He’s full of his normal sweetness, kissing your cheek as a hello and giving you a bouquet of expensive-looking roses. Always roses.
You find a container for the roses and watch him get to work, hoping you're doing enough to hide the burn building in the pit of your stomach. You stare as he unloads the grocery bag he brought with him; He starts prepping for dinner while you lust quietly from the kitchen island.
If Nanami had a love language, it was definitely ‘acts of service.’
He memorized your routine, your favorite foods, and music preferences, all so he could add a little to your everyday life. The effort he exuded during your entire relationship was enough to make you swoon.
Surely he could feel it too.
You do notice a few things: his grip is just a hint stronger, and his hands are heavier as he moves around. His brows are permanently knotted together, and you feel him watching you from the corner of his eye.
He knows something is wrong.
“I'll finish getting dressed.” You barely get out without a moan, standing next to him and leaning to kiss his cheek.
Your lips tingle and your mouth practically waters at the scent he’s giving off, warm and strong and absolutely intoxicating. Your nose lingers close to him for just a moment, savoring the sensations it sends through your body.
He hums, standing stiff at the stove as he watches your dinner cooking, his grip on the countertop turning his knuckles white.
Once you turn the corner, you rush to get ready, fueled by the delicious ache that has settled in your body. Something primal and desperate takes over your being, practically ripping off your robes and searching in your closet for the perfect outfit.
He never specified which dress to wear, only that it should be one he bought you.
You hold the silken fabric between your fingers and outwardly moan at the softness. The blush colored teddy was one of your favorites and had been purchased by the one and only Kento. You slip the ‘dress’ over your head and pick out the matching underwear, slipping them on and whining at the slick already covering your thigh.
Surely he had to know what was happening.
He was probably seething even from the other room, large and powerful, just like any alpha would be with a mate in heat.
You’d never even asked if he wanted to use that label. Mate.
You’d been together for a while, and you have no reason to believe he’d reject you…
And yet the sudden realization that he had never officially claimed you brought you to a screeching halt. You couldn’t take it if he didn’t want you; you’d certainly wallow away for days in mourning.
Another rush of heat snaps you out of your worries.
Your body felt on fire before, and now it felt like an inferno.
He knew. He had to know now.
You felt his scent wash over you, overwhelming with hints of clean, crisp pheromones he normally exuded. For a split second, it satisfies you, the feeling in your cunt going from pain to unbinding pleasure.
You take a deep breath and walk back into the kitchen.
You stand quietly at the edge of the threshold, waiting patiently for him to turn and acknowledge you.
He visibly stiffens his posture, inhaling deeply like he needed to savor the scent in his lungs for as long as possible.
“Do you know what day it is?” You barely squeak out, batting your eyes when he turns to look at you.
He arches his brow, and for a moment, you feel like you're under his scrutiny.
“I can’t be sure but…” You pause to take a deep breath. “I’ve obviously grown a bit…needier.”
“I’ve noticed.” He says with a level tone, his jaw tensing as he looks you over.
“That is dangerous.” He says quietly, like a warning.
It’s your decision to make, but once you cross that line, there isn't any way to turn back.
You slowly take a step forward, then another, and you’ve practically closed the distance between the two of you. He smells sweetened almost, still so powerful but sticky and candied as it fills your senses. You meet his eyes and nearly faint; his entire demeanor has changed. His eyes were still sharp, brow strong, but now you could see something lying beneath the surface.
You gently take his tie in hand, wrapping the silk around your fist. You tug until he’s much closer, your noses nearly touching.
“Not..” You start, your mind blurring with thoughts of nothing but being filled by the man in front of you. Images flash behind your eyelids of exactly what he could do to sate your needs.
“Not when I have my big, strong alpha with me.” You touch his chest, walking your fingers up to the knot in his tie, then dragging your nails down his chest.
He all but growls, prepping to speak, but you stop him with a finger to his lips.
“I wanna be all yours…” You admit quietly, the air so still you could hear a pin drop. “I want your claim on me…”
Once you got started, you found it hard to stop.
Plus, the look on his face is one you’ll never forget.
“I want other alphas to know your scent on me, so powerful it makes their throats fill with bile at the thought of trying to take me from you.”
“You are…” He grits his teeth, obviously trying to restrain his instincts.
He had an omega, desperate and in heat, begging for him, and he kept it together.
Barely.
“Sweetheart, this is a very…”
You lean forward and kiss him. Tired of talking.
The noise he makes comes from deep in his chest, and it shoots straight to your core. He grabs you and digs his fingers into your flesh, gripping your curves so roughly, but you moan and lean into his touch.
Just as soon as you press into him, he has you turned, facing away, and pinned between him and the kitchen counter. His hands run up your sides, squeezing his favorite spots before his hand reaches into your hair and grabs a fistful, jerking your head to the side and displaying your neck for him.
He presses his nose directly on your scent gland, inhaling deeply and growling, an incredibly primal sound that shoots to your core.
But just as you begin to enjoy his touch, he pulls away, the heat from his body vanishes like a flame quickly extinguished.
“Bedroom.”
When he speaks, you almost don’t recognize him; a mixture of fear and admiration burns in your stomach.
“Now.”
-
You lost count of the hour.
In your haze, you look over to the clock on your nightstand and note the time, 3 am, hours after the original date began.
Your mind is in a haze, your body washed in a delightful tingle as you cum on his cock again. A simple ‘thank you’ is the only thought you can form, just like you thanked him for every other orgasm he gave you.
“We're not done yet.” He rumbles, leaning over your body and pressing his weight into your back.
He fills you to the absolute brim, kissing your face and neck before he shifts his weight to start fucking you again. Your face is buried in silk sheets, your little grunts of pleasure being lost in your plush bedding, while the smack of your bodies together fills the room. His hips snap into the flesh of your ass, his fingers digging into your skin as he holds your hips up enough to hit deeper.
He grabs your wrists, safe behind your back, and tucked firmly between the silk of his tie, wrapped in a pretty bow. He uses the leverage to pull you, your back arching, and your head lolling back to look at him. He presses a gentle kiss to your forehead.
“Just one more, yeah?” He pants, cupping your jaw with a strong grip. “You give that to me, sweetheart?”
You nod, feeling a fresh wave of arousal wash over you at his words. Your cunt squeezes, the mess between your legs grows, and continues to leak onto the bed. Every one of your senses bowed to him, your body ached deliciously, but you could tell it was only for him. His very essence was burning through your skin, but the sensation felt like home.
Like you belonged to him.
“Then I’ll do it. I promise.”
Your heart flutters, and a jumbled mess comes pouring from your lips, your entire being reacting to the news you’d soon be marked, claimed by the man you love.
“I’ve got you, sweetheart.”
He lets you lie back down, spreading your legs wider and angling your hips to his liking. The excitement that surged through you brought you so close to your finale, just a few thrusts of his cock has your blood boiling, and you teeter closer to the edge.
“Kento…” You moan as he presses into you, covering your body with his. “Alpha.”
You correct yourself, feeling his cock pumping into you one final time, his knot swelling until your cunt is stuffed to the brim.
It is a delicious ache, the beautiful stretch of his knot pressing into you. Before tonight, you’d never experienced an alpha so intimately, but every moment of it felt right.
All because of him.
He brushes some of your hair out of the way, running his fingers over your scent glands. It sends a shiver down your spine, words sputtering out of your mouth faster than you can comprehend them.
“Please, Alpha. Please, I need your mark.”
He growls and it shakes to your core, nuzzling your skin with a few reassuring pecks.
“Patience, sweetheart.”
He rocks his weight back and forth inside you, the pressure of his knot making your cunt flutter around him.
“It’ll come.”
You whine, rubbing your face against his cheek to sate him, hoping a little pathetic begging will make him bend.
“Patience.” He repeats, authority laced with each syllable, and sends a sharp chill down your spine.
He keeps rocking his hips, careful and calculated with each movement.
“So…’m so big.” You babble on, nothing but pure bliss circling through your mind.
He chuckles, pressing his nose into your shoulder and trailing delicate kisses along your skin. He makes his way to your scent, pressing his nose closer to inhale you, just as he did hours ago.
You feel his cock throb again inside you, his cum filling your messy cunt again. You whine, realizing his cock has filled you beyond measure, the burn and ache subsiding in that moment.
Weaker, but the sensation is not gone.
You reach for his free hand and your fingers intertwine with his, squeezing him as hard as you can, though you know he barely feels it. The ringing in your ears disappears as he whispers sweet little nothings, an action you're entirely familiar with.
This was his routine to wake you in the morning, his pastime as you lay together on the couch watching bad reality TV, something that made you feel so loved and so special just because of him.
“Alpha?” You say pitifully.
“That’s it, sweetheart.” He breathes, dragging his teeth along your scent.
“Omega.”
He sinks his teeth into your flesh, and you squeal, squirm what little you can under his weight as the feeling of him washes over you one final time.
This time is different; everything about his being seeps deep into your core, and it doesn’t dissipate shortly after like all the times before. He was all over you, twisting and circling your body like deep, thick roots that pinned you in place.
Your mind clears very quickly, the fog of arousal that had you in a bind finally gone, and the world returns to normal.
And all you could feel was him.
You hum happily as he licks and kisses your neck, murmuring your name over and over, along with your signa.
“Omega. My omega.”
