Geto had been Gojo's beta; a right hand man to his close friend, and one of the only beings Gojo could trust with his life. 

Among those people, you had stood proudly. 

You hadn't been aware of this, though. Gojo's characteristic coolness when around you, the tilted smirk and smooth words he'd use purely to fluster you had been ones you'd assumed him to use on many - but this fact would be wrong. From the moment his pretty blue eyes had laid on your warm skin and wide smile, he'd sworn his heart had felt fuller. 

Gojo had found you irresistible for many reasons. Your hard working nature second to the sweet face and laid-back attitude you'd displayed so easily to him; your presence had been his favourite within the office after only a week of knowing you. He'd been head of Gojo Inc, a face you hadn't expected to be a regular part of your working day, yet he'd made time to spend with you each afternoon. A few colleagues had commented on the uncommon interaction between himself and a lowly administrator, though all had met with disciplinary action from Gojo himself. 

Geto had theorised you to be Gojo's fated one, though he'd brushed this off - mates were a kind story told to desperate wolves on the brink of insanity. A last resort to runts, a desperate grab from an alpha to keep their packs sane. And, if a fated being had been true, how could it be that the moon goddess would pair him with a human? No, you were simply his muse; a fresh face and a new toy to play with. Gojo had restraint and had known not to take this further than flushing you in conversation or causing heart to race, a close proximity between he and you within the confides of the elevator - but, what was this smell? 

Ovulation had been a thing you'd noticed, but ignored. Being single and years from settling down, you'd paid little attention to the changes your body made each month - the only difference in routine had been increased use of silicone toy. 

"Are you okay, sir?" 

You'd stopped mid conversation as Gojo's eyes had glossed over, chest rising and falling at noticeable speed. He'd been looking at you, you'd been sure of it - yet, he appeared so hollow. So, for lack of better word, feral. The gaze set upon you had been one you'd never met with before, one that had made your stomach churn in both curiosity and fear. 

"Sir?" A second prompt before the elevator dinged, silver doors pulling apart to reveal the tenth floor and Gojo's stop, yet he hadn't moved an inch. The doors had begun to close as the interest you'd felt had instead stemmed into an uncomfortable feeling, mouth opening to protest the unusual action and to perhaps flee the elevator before the doors had closed completely. For some reason, you'd felt if you'd stayed within that spot, Gojo would have lost control. Over what, you'd been unable to tell. 

The steel had almost closed shut, your exit fading before you, though as if a sign from God, a large hand had met with the thin gap. The doors had parted once more, Geto allowing no hesitation before stepping into the elevator. His arm had grazed you as he'd practically ran in, palm reaching to his friend's slouched shoulder. You'd watched as the glassy blue eyes had widened, panting chest turning back to shallow breath. 

"That was close, Satoru." Getou's voice had been low, concerned gaze fixated over Gojo. As you'd stepped out, doors edging closed to leave two males within the metal contraption, you'd made out the peculiar sentence that had left you questioning both their sanity and your own:

"She's in heat." 

Throughout the day, you'd questioned that phrase. Filing paperwork had felt near impossible as you'd reenacted that scene from the morning, a daunting feeling rising when remembering the look of hunger within his eye, the odd term he'd used - could men sense women's ovulation? 

You'd googled it, thumb shaking over search bar from both embarrassment and fear, a sinking feeling within you as you searched to find if your school system had failed you. Though, after extensive research (five minutes of searching through mildly related articles) you'd come to the conclusion that ovulation had in fact been undetectable by other people.

Though, you'd known he'd been aware of your bodily situation. Even if you couldn't pin down how or why, you'd understood Gojo's look to be that of lust, a predatory gaze only a beast would give their prey. 

Yet, you hadn't felt fear. 

From the moment you'd stepped foot in his office on the date of your induction, you'd felt a warmth and homeliness within Gojo you hadn't found elsewhere. There had been a peculiar aura around him you hadn't felt before, and although some had felt agitated by the authority he'd radiated, you'd wanted nothing more than to push his boundary. To get to the bottom of the burning questions you'd had - even if that had meant playing with fire. 

So, you'd taken a risk. 

A pile of paperwork in hand, you'd stepped foot back in the elevator and pressed finger onto 10 with trepidation ebbing through vein. Your heart had raced with knocking fist over door, though the strain in Gojo's voice when allowing admission had only added to your sureness that he'd been able to sense you. 

You'd clutched the files in your palm, fingers wrapped tightly over plastic binder while you'd closed his office door and taken steps closer to his desk. 

You could feel it, the tension in the air as you'd grown closer. His eyes had watched you through pain as he'd sat straighter in his chair, smile forced.  "Is that the reports?" His voice sounded higher than usual, a strain in throat. 

"Yeah, I've completed them all." You'd placed the pile over the wood of his desk, arms less burdened. Though, now you'd had nothing to squeeze your anxieties into. 

"Uh, Gojo?" His lack of response had been unusual, though after your previous encounter, you'd expected nothing less. The same pained expression had stared back at you, glossy eye and hollow gaze. The more you'd peered into the blue, the more you'd deciphered lust. 

"What did you mean, earlier?" The question had been whispered, though he'd heard you loudly. "In the lift." 

Gojo swallowed. Beneath his desk, his cock had twitched, an uncomfortable tightness within slacks as he'd shifted his hips. Your scent had been divine. He closed his heavy lids to breathe deep once more, a groan stifled in throat as the sweet musk had flowed from your being, calling to him. 

"Sir?" Your voice had grown timid, and when Gojo's eyes had opened once more, he'd found you bending toward him. This had been enough. 

Your concern had irked him enough to place hand roughly to shoulder and push you backward, your behind coming into contact with the smooth wall beyond desk. The startled expression plagued with worry had been a bi-product of his rash action, yet Gojo had only found his lips curving into a smile. You'd been prey, after-all. 

"Stop playing dumb." His words had been whispered against the skin of your neck, a barrage of goose-bumps decorating the skin he'd touched. Suddenly, you'd felt prickled with heat - a burning you were sure had started within your core. 

"What did you mean, Gojo? Can you-" You'd cut yourself off from asking, though when your eyes had met his once more, pupils blown out and teeth sharp, you'd felt inclined to ask what had felt to be a ridiculous question. "Can you tell I'm ovulating?" 

He'd laughed, bitterly. 

"Is that what you call it?" His fingers had grazed your neck, sitting beneath chin to push your face upward. He'd stared into your gaze, basking in your attention. 

"Gojo..." You'd trailed off, the warmth over flesh turning into an unbearable itch. "What is this?" There had been a draw toward him, a magnetism through every inch of your body that had felt insufferable to bare.

"You're a bitch in heat, aren't you?" His lips were much closer to yours, now. There had been a part of you that had told you to run, yet the throb between thigh and need to connect yourself to him had felt much greater than the fear sinking in your stomach. Instead, you'd closed the gap. 

Gojo's mouth was warm - in fact, every part of his pale skin had felt hotter than you'd expected it to be, almost as if he'd suffered a fever. Though as he'd pushed his tongue into your parted lips and pressed his body closer to yours, you'd understood he'd simply been different to the typical human. There had always been something about him, a draw toward him that hadn't felt healthy nor natural, yet his mouth taut to yours had been the only relief you'd felt in the past week. 

The glossy lips trailed to your neck, teeth grazing skin as he'd nipped over thick flesh.  "You're mine." Possessive words had ricocheted from your skin, his hands now gripping over thigh to lift you against him. 

"What is this, Gojo?" Somewhere in your voice had been concern, though your mind had felt lulled when his cock had pressed to your core. You'd wanted him, more than you'd wanted anything in your life. 

"You smell so good." He'd spoken against you before inhaling once more, a sharp breath inward to take your scent into lung. "Intoxicating." Gojo had groaned into you, a squeeze of grasp. "You're in heat - that means you're mine, you know?" His rambles had been paired with ruts against you, the friction of his clothed cock against your body serving as the only thing grounding him within that moment. 

"Humans don't go into heat, not unless they're fated to us." Another rut, this one catching the parting of your lips, tip pressing over your clit. You whined, slick coating underwear thickly as he'd rolled against you. 

"I need you, Gojo." Your request had been a desperate plea, the prickling sensation throughout your body in need of soothing, body clenching. 

"I know, love." 

Gojo's hands had gripped you firmly as he'd carried you to the fur rug in the centre of his office. This hadn't been where he'd wanted to take you, but you'd needed him - and he'd been inclined to soothe your pain, after all.

"So pretty." Whispered against stomach, Gojo's fingers had hooked through your pants to pull them lower, flat palms scaling exposed skin. He'd spread your legs open wide, pressing into inner thigh to keep you parted as his head had grazed across your slick, a lewd whine from your lips as you'd raised yourself toward him, begging for more. 

He'd given you what you'd wanted, pushing himself into you with ease, a groan tumbling from lip when feeling your tightness hug around his length. You'd felt perfect, sucking him in with ease - though the abundance of your own arousal had aided with the tight fit. 

Your sensations had felt heightened beneath him, the draw of his length within you creating a jelly within your head. Though, with his cock buried within you, the heat had faded into a soft lull, a static within brain. 

He'd bottomed out when reaching for the buttons of your shirt, nimble fingers popping plastic through hole until your chest had been exposed. The white bra you'd had beneath had pushed your chest upward, curve of breast accentuated. He'd pressed his hand into your chest, a rough squeeze with a rock of his hips as you'd contorted your face beneath him. 

"Feelin' better?" He'd asked you through the snide grin across his face, cock twitching within your confines as you'd nodded with urgency. "I'll take care of you." Gojo hadn't been sure if the statement had been one he'd used to reassure you or himself, though he'd felt his head throbbing from within you from his protective phrases. He could sense your malleability and trust beneath him, the innate safeness and faith you'd allowed him to have. This had been enough to prove your loyalty, and compatibility. 

He'd manoeuvred his body to allow hand between his abdomen and yours, fingers coming into contact with your slick folds to roll his finger over sensitive bud. You'd arched your back immediately, soft whimpers encouraging the circles he'd kneaded into you, cock bullying deep into your core. 

You'd sworn under your breath, arm brought over face as you'd felt overcome with pleasure, walls stretched against his thickness and mind foggy. With the swipes of his finger, you'd felt a familiar build up within your stomach, back arching above the rug. 

"D'ya know what knotting is?" Gojo took the decency to ask you before it would happen, a flutter in chest as he'd awaited your response. Of course, the human you'd been, you'd shaken your head and allowed confusion to take home over your features. "I get thicker when I come - to keep it all in." 

Your furrowed brow had been all he'd needed to see, a mental note to explain his kind to you extensively once you'd felt satisfied. There had been a long way to go with you, though this wasn't anything Gojo wouldn't be prepared for. His heart had beat with yours, another roll over you as you'd felt stuffed full. 

"Want you to pull out." Your demand had pained you to say, yet you couldn't push logic out completely. You'd still been ovulating, and without protection had been risk enough. Gojo laughed, bending forward to place lips over cheek.  "Not giving you pups yet, love."

You'd whined, the sudden change in proximity feeling wildly more intimate. Gojo had felt this too, the satiation when you'd been closer to him. He kissed over your skin, trailing messily to neck as you'd clenched around him. You were close, he'd felt that through the grip over his length like a vice. 

Your strained moan and head thrown back had spoken as evidence to your undoing, Gojo's cock pushed deep within your aching hole, fingers working magic over swollen clit. He'd grunted in a response to your high, an inhuman snarl erupting from chest - though you'd ignored the animalistic sounds he'd made in favour for your orgasm. If anything, the feral groans had only coaxed pleasure from you, a warmth in stomach at the comforting sounds. 

Only when your high had fizzled out, legs loosening from his waist had Gojo pulled out, curses and groans tumbling from parted lip as he'd pumped his fist over himself. Hot white had spilled over your stomach as you'd watched him through half lidded eyes. 

When Gojo had come down, he'd leaned forward to nuzzle into the small of your neck, sharp breaths in to take your scent in once again.
