Chapter Text
Could life get any fucking weirder?
It was the question that Ken Takakura had ended up asking himself multiple times per month (sometimes per week) in recent memory - at least ever since Momo Ayase had stepped into his life and changed everything.
They were both nineteen now, and he had been in love with her pretty much since they met two years ago. But there was no way he could ever tell her, of course.
He was grateful to her, endlessly and eternally, and he wouldn't trade the alpha's friendship for anything in the known (or unknown) universe, he would never risk that. No secret knowledge or alien technology or cryptid phenomena could alter that absolute certainty. Miss Ayase was a constant in his life that he relied very heavily upon.
Ken wanted to provide that kind of stability to her, too. And for nearly two years he had - as her steadfast, secretly adoring, beta friend. Nothing more, because how could a girl as amazing as her ever want to be with a boring ass reject like him?
Fighting (and defeating) literal armies of monsters, magic, yokai, aliens - all things hellbent on destroying the place they called home or experimenting on their bodies - had become commonplace. His lanky, dangerous turbo mode snapping into and through whatever got in her way - and her dazzling turquoise hands shimmering through the battlefield right behind him, protecting him just as often as he did her. They were a rock solid team, a true force to be reckoned with.
As more amazing friends joined their group (other alphas and betas), they only grew more formidable and more tightly knit. Even among their many friends, Ken knew he could seek out Momo's hand in his own and she'd lace their fingers together in a heartbeat. Never fading into the background as long as she was there, she wouldn't let him.
Which made the past three days of him trying to avoid her hurt like hell as he was wracked with guilt over the foundations of their friendship and his silent feelings.
Claiming illness and fatigue, he'd skived off school for two days, until the relief of the weekend approached. Miss Ayase had no idea where his apartment was, and he only needed a couple more days to get over his… problem.
It had all started with nausea and back pain just after a fight, he was concerned at first that perhaps he'd been injured in their throw-down with the Serpoians. Except for the fact that when Momo pulled him into the circle of her arms and tried to feel out his aura for any potential harm, her scent washed over him like a thick blanket and he'd damn near passed out from the soothing balm it provided. She smelled so very strongly of coastal flowers, heavy charcoal, and the tang of sea salt - sweet and floaty and overwhelming, and if he could bury himself in her clothes in that moment, he would have.
He'd always privately thought she'd smelled quite nice, especially when he could still scent her on the collars of her borrowed sweaters or the blankets in her room as he laid in the futon on the floor. It had never been this intense before, though, not even the few times they'd ended up falling into the same bed to sleep after a particularly rough day. Floral scents weren't unheard of in alphas, but it was considered rare… then again, so were female alphas.
The pain was somehow eased the more he eagerly sucked in the strong smell, and as he unwittingly pressed his nose into her neck while she held him, he felt something completely new; a small gush of sticky wetness.
Between his legs? Accompanied by his normally subtle scent of graphite, ink, and old books, but amplified by about a hundred times, with the new aroma of strong, freshly brewed coffee thrown in by a particularly indulgent hand.
Ken saw Momo's nose twitch and transformed faster than thinking, almost going All Out in his attempt to get the fuck away from her even as everything inside of him screamed and clawed at his brain, begging him to go back to the shelter of his alpha, to stuff himself under her chin and nuzzle deeper into her embrace.
His… his alpha? Fuck.
Breathing thickly on the opposite side of the warehouse they were in, he noticed that his scent had faded in this form - almost back to the subdued library he always thought he was rather lucky to smell like. His lower back was hurting again as the smell faded away, a steady and pulsing clench of muscles intensified.
'What the fuck is happening to me?' he growled internally, steam hissing out of the great yokai maw wrapped around his face. Thank goodness for his curse form, always expressionless and neutral, or he'd be done for based on the yelling coming from Miss Ayase's direction.
Jiji trotted up, still wet from where they'd splashed him with hot water from a utility sink, "Heyooo, Yoka~run, what is up, my man? You alright, dog?" Ken would have smiled reassuringly in his normal form, but when he was wrapped up in the blacks and reds of Turbo Granny's power, that wasn't an option.
So he adjusted his round glasses slightly and shrugged, "Feeling like a bummer, yo." In the back of his mind, he noted the pain worsening the longer he stood there, and rumbled out a groan at the rolling sensation of his stomach. Even in this form he couldn't seem to escape it. Jiji's scent was also much stronger now (a pleasant teak wood and citrus), though not anywhere near as potent as Momo's - it also did nothing to ease his pain or cloud his mind.
"Hey Momo, uh, I think something is up with Okarun? Uhhh, he's actin' a lil down." Jiji waved over Momo and Ken found himself stepping back away from her again. She stomped closer and pouted as she tried to get him to meet her pinkish eyes with his vermilion ones. It made his teeth ache but he resisted the urge to lean toward her and rest his huge jaws on top of her shoulder for a break.
"Okarun! What the hell… what's up with you?" Her eyes colored with concern and the annoyance stumbled right off her face, but as she tried to step closer again, he realized his back was almost against the warehouse wall and he had nowhere to flee to.
Holding up his hands in front of him in what he hoped was a casual gesture, Ken muttered, "I'm cool, babe, don't worry about me." Maybe it was the lackadaisical nature of his cursed form, but she let it slide and they finally headed back to the Ayase household to recover.
Trying to stay on the other side of their little group (only Jiji had been with them for this fight, everyone else had been busy after school), Ken stayed in his yokai form, which only seemed to worry Momo more. He told her he just had too much energy still and that he'd shift back soon, but when they got to the Shrine he changed only long enough to say goodbye.
Momo had come in for a hug and he panicked, already feeling her scent roaring down on him like a tsunami; and as much as he wanted to revel in it and be totally consumed and carried away by her, he didn't want her to think he was even more of an obsessed weirdo than she likely already did. So he waved (extremely awkwardly) and ran before she could get a word in edgewise, sprinting toward his lonely apartment at a breakneck speed.
Then the fever started. Ken felt like his skin was about to melt off of his body by the time he twisted the key in the locked door of his apartment. Nobody was home, of course, it was only ever him - and thank god for that because what the fuck was happening to him?
He could hardly breathe through the weirdly thick scent coming off of the glands on his neck, and a quick and painful brush of his fingertips revealed that they were swollen and almost wet in agitation. He was thankful that he'd never gotten around to replacing his cell phone after their initial Turbo Granny misadventure - he's pretty sure Momo would have been blowing it up with texts and calls.
Throwing himself into a cold shower was a bad idea, turned out. He tried his damnedest, but his internal temperature didn't go down at all and it felt like getting pummeled by needles of ice, so he only managed to stay under the spray for about two minutes before lurching out of the stall with a gasp.
Next came the piling of fabric on his bed. His room had always been his safe space in the tiny, shitbox apartment; it felt the most secure, it made sense to want to… burrow there? What didn't make sense was him dragging out every article of clothing he had that Miss Ayase had ever loaned him (and he hadn't returned yet)… and weaving them all into some kind of… nest?
Oh, shit.
Tearing himself out of his nest- BED! Bed! Ken raced through the apartment to grab the decrepit laptop that he'd left on the coffee table in the little living room and retreated back to his room ('safe in here, not out there, don't leave, just stay where you can smell Momo and you'll be-')
Slamming the door to his bedroom in reality and the door to those thoughts racing through his mind simultaneously, he clutched the laptop to his chest and eased back into the… bed.
Letting the ancient brick boot up took several long minutes and Ken ended up scratching delicately at his prominent scent glands and pulling one of Momo's sweaters up to his face to rub into the cloth. Her smell barely clung to the fabric but it was all he had. But then the most obscene, desperate whine crawled out of his throat that he immediately dropped the sweater in his lap and bit his lip hard enough to taste blood. He could feel tears gathering in the corners of his eyes, and he was so close to sobbing that it was unreal, when the laptop's startup noise finally sounded.
Navigating to a search engine (and then waiting for the slow ass thing to load), he typed in his symptoms, an theory repeating loudly in the back of his head that he was trying so hard not to give voice to.
The dam broke and tears streamed down his overheated face as the words on the screen confirmed his fears, however…
He wasn't a beta at all, at least not anymore. He was an omega, and this was his first heat.
A few hours after collapsing into a heap and crying until he couldn't breathe, he crawled out of his clothing pile (he'd torn half the nest back to pieces in a fit of rage and anxiety, then just laid under it pathetically) to poke at the keyboard again, searching for more answers. His parents had both been betas, even his grandparents - he thinks there's only been one alpha in his family tree in around four generations, and no omegas at all. So why the fuck would he suddenly present as one?!
"Biological Imperatives: Bonding Gender Changes In Non Mated Pairs", the article headliner reads, and Ken gulps as he devours every word over the next fifteen minutes, his gut in the tight grip of fear and confusion again.
"By sharing articles of clothing with each other's scents, a beta can become-"
"Finding themselves in sexual or nonsexual intimate confines on a frequent, often daily basis can cause-"
"Frequent touching of skin is also-"
"All of this coupled with strong emotional connection and amorous intentions can, indeed, force a change in biology-"
'Oh… fuuuuuuck,' Ken thought to himself wildly.
Being so close to Miss Ayase for so long, sharing clothes, constantly touching and being around each other, even sleeping in the same bed sometimes! He didn't know this could happen, nobody ever told him to watch how much time he spends around an alpha or he'd grow a fucking uterus!
And on top of all this, he had to go and fall in love with her, like a fucking dumbass! She wouldn't choose him normally so his stupid body had to jump the gun and try to push the issue! God, he felt like a scumbag. He was the worst fucking friend and Miss Ayase deserved so much better than someone like him, who apparently would alter his fucking DNA to try and lure her into a relationship.
This cloud of sorrow hung over him for the rest of the day.
He skipped the next two schooldays, which was expected, according to the internet - it was easy, he just sent in an email from his mother's account explaining that he had the flu. Omegas should never be in a public place for their first heats, regardless of how late they are presenting, even Ken knew that much. It was typically preferable that they had the knowledge that they could be an omega before going into it, obviously, but he was working with what he had…
Which was wadded up toilet paper and a pile of dirty clothes when the toilet paper wasn't enough to absorb his… slick. Fuck.
Crawling out occasionally to grab a bottle of water or granola bars to choke down (he really, really didn't feel like eating, something to do with having a vagina growing up his ass apparently, but he tried to anyway), he noticed that the whole damn apartment was starting to smell like the kind of library that you'd find in a university or a museum - one with incredibly aged books, countless students scribbling notes, and a nearby coffee shop running 24/7 to keep them all awake and reading.
But heats typically only lasted between four and seven days. He could get through this - it was Friday now, he was already three days down. He'd be back to normal and in class on Monday and nobody would ever have to know. There were suppressants he could order online, he'd be fine.
Yeah, right.
Lurching into the small kitchen, Ken bleakly took stock of his situation. He was embarrassed, lonely, horny as hell (though he didn't want to admit it), and so fucking angry at himself. And he ended up rebuilding the nest, goddammit.
Which is probably why he started bawling when a noise made him turn around, wearing nothing but a thin sheet draped over his shoulders and sleep pants, to lay eyes upon Momo Ayase hanging onto the door frame of the entryway like her life depended on it.
Oh shit, she um… she figured out where he lived. And she looked so fucking pissed off.
"Oka-" Momo gasped and covered her nose with a hand, fumbling with the door to try and shut it behind herself, closing them both in to the small space, "Okarun, y- you… since when are you a fucking omega?"
Cringing back in shame and fear, Ken's shoulders hunched up around his ears and he turned his neck to display his glands to the alpha in the room. God, it was a pathetic display - and that's exactly what it was, a display. Instinctual, unavoidable, and fucking embarrassing.
"I know! I know, I'm so sorry alph-, M- Miss Ayase, I just… I wasn't, I swear! It just happened," he whined pitifully, tears still coursing down his cheeks, and his fists clenched in the sheet he held shut around his flushed chest. He had no idea how to even begin to fucking explain this and his hormones were fucking him up and he knew getting upset was just making him scent more.
Momo's pink-brown eyes were quickly being overrun by her black pupils, sucking in the color of her irises and pulling at the inhibitions he was clinging to so tightly. It was all he could do to just stand there and not fling himself to her feet to plead with her to help him, to fix him, to take care of him-
Miss Ayase snapped those thoughts in half, his brain stuttering to a halt momentarily when she whipped around to face the wall, covering her nose with her arm and breathing heavily.
She was rejecting him, his nervous brain screamed, bound and gagged by unfamiliar instincts.
'No, she's trying to be good and kind, she knows I can't help this and isn't going to use me like I'm some toy!' Ken corrected himself fiercely.
But what if he wanted her to? God, he wanted her to-
'That's the hormones talking, that's not… it doesn't matter!' he argued weakly.
But maybe it should matter. He saw that note she'd left him, it said she loved him. She'd caused this just as much as he had-
'I won't do that to her!' Ken shouted at himself internally, and then clenched his fists and slowly forced his body to twist around, facing away from Momo. This wasn't a natural position for an omega to take with an alpha, presenting your back is almost the clearest sign of refusal that there was.
But what Ken was refusing to do was to take that choice away from her with some stupid pheromones - and ohhhh how fucking wonderful she smells right now, he could swear it's getting stronger. He hears a shuffle behind him, and he's holding his breath, waiting for the inevitable sound of the door closing on him, on their relationship, forever.
Then one of Momo's hands rests delicately against his shoulder blade, only the sheet is in the way and it is nowhere near thick enough to prevent the flush of heat coming from her tentative touch.
"Okarun?" she asked quietly, he trembled and it felt like his bones were going to shimmy right out of his skin, and he was covered in sudden static electricity at the light press of her fingers. He was dimly aware that his hands were slipping on the sheet, almost subconsciously dropping it so there would be nothing between her skin and his.
"Y- yes, Mo- Miss Ayase?" His response came out as a shudder, on an exhale that barely clipped it's way over his teeth. Every nerve in his fucking body was on fire and standing at attention to hear what she was going to say.
"I'm… I'm sorry, Okarun. I, umm," her voice was choked up and a little muffled, maybe she was covering it somehow to block out his scent, which was pouring off of him like some cheap perfume he'd upended over his head, "I didn't mean to upset you. If you want me to go, I will. But if you…"
Clenching his teeth, Ken barely kept himself from whipping around and clutching at her in desperation, he could sense the slick pooling inside himself again and he fucking hated how good it all was starting to feel. He waited near silently (he was breathing so loud and hard suddenly, and he didn't know how to stop) for her to continue, the weight of her hand searing into his shoulder.
"If you… want me to stay, I... I don't want to leave you alone. But I don't want to- to take advantage of you, either. We've been kinda… look, we've been dancing around this thing between us for a long time now. So, if there is any part of you, any part at all that doesn't want me like I want you-"
Momo didn't get to finish her thought as Ken let the sheet fall away and drove himself into her chest, nuzzling up into the skin of her neck and rubbing his cheek against her scent gland in a frenzy. The slick soaked right through his pajamas and he couldn't find a single fuck within himself to give.
She wanted him, too.
His alpha, so gorgeous and powerful and gentle and kind… but she'd still chosen him.
He was her omega.
Ken didn't have the first clue what he was supposed to be doing, he'd done a little bit of research once he'd resigned himself to the fate of having forcibly evolved into a completely different gender presentation, though it wasn't enough for his panicked brain to grasp. He was moving on pure instinct and raw need.
But as Momo wrapped her strong hands around the back of his head and neck and pressed him in closer to her glands (rubbing firmly into him as well), he whimpered and let his tongue drag across the skin, so drenched in her scent and her taste that he could have been smothered and still be ecstatic for it.
It felt like the blood within his skin was magma, pouring thick and slow through overheated arteries and veins, lighting him up from the inside out as Momo pulled his head back by his hair (so gently that he whined at her tenderness) and pressed her nose flush into his swollen scent gland, inhaling deeply. Then her teeth lovingly, gently encircled the gland and Ken felt his knees go weak and start to collapse, supported only by Momo's unyielding strength.
The string of whimpers and repeated pleas that came tumbling from his lips as she worried his neck and the gland with her teeth were frenzied, desperate, and positively obscene. And she growled through them and pulled his body closer, hefting him to her in a snug princess carry as she released his neck from her hot, wet mouth with a loud pop.
He felt not quite in control of his limbs; he was stroking at her lovely face, her muscular arms and shoulders, and constantly pressing himself into her skin ever harder. Momo was shushing him, holding him tightly as she made her way slowly through his tiny apartment, heading for where his scent had gathered most: his bedroom. Knocking the door open with a bump from her hip, his noises halted completely, awaiting his alpha's reaction to his nest. The nest he'd unwittingly (or perhaps far too wittingly) prepared specifically for her, for them.
"You've been working so hard, Okarun," she hummed into his hair and she inhaled deeply, he was pleased and wriggled within her strong grip, "What a good nest you've made for me, I'm so proud of you." Ken felt like his heart could burst inside his chest and he'd thank her for it with his dying breath so long as she continued her praise.
Momo began to release him and he whined in agitation, but she nuzzled into him and puffed out more of her scent over his hair to soothe his anxiety, "Just being careful with you, want to take care of my sweet omega." And indeed, she was lowering him gently into the nest, taking great caution to not mess up the woven clothing around the edge. Ken found himself preening and another gush of slick coated his inner thighs, his newly realized coffee scent and intense graphite aroma clearly affecting the alpha as she inhaled sharply and moaned. The sound rattled around in his rib cage and made him ache with want.
The sight of Momo Ayase crawling up his naked chest, her fully pink eyes tracking his own, was one he never let himself think of, even on lonely nights waking up with sweaty and sticky sheets. She had always been several leagues out of his, and only the most vague of sensations of skin on skin and so soft lips latched onto his neck and his ears had ever managed to worm through the mental barricades he'd placed to assault him in dreams. Momo, his first and dearest friend, was always not allowed.
Until now.
Ken felt like he was going to shake apart into pieces as her weight settled on top of him, his heart was trying to climb out his throat, accompanying the long and incredibly needy whine making itself known as parts of the woman he'd been in love with for literal years brushed against parts of him that yearned. She was straddling him currently, but oh, how he wanted her pressed between his legs instead.
Momo's hands cupped his face as she hovered over him, he could feel her hard length against his stomach, bumping against his own and sending shocks running up and down his spine. "Are you still feeling alright, Okarun? How can I help you?" She was so perfect, so beautiful, so overwhelmingly lovely that he felt more tears drip down his face at the look of total devotion he saw reflected in her gaze.
"Pl- please, M- Momo, please, I need you," he was basically sobbing, trying his hardest to stay still underneath her, but his hips were twitching, his pajama pants were a sopping mess, and her penis caught on his own weeping one and he gasped at the sensations, his hips jerking up violently for more contact without his say so.
Momo smiled, indulgently allowing him to grind himself into her before leaning to whisper in his ear, "I'll take care of you, I'll help you, Okarun," she was cooing, hot breath blowing into his ear and hair and making his head swim with desire as her floral scent enveloped him more, hydrangea and the crisp sea air, "Let me make it all better. Let me show you how much I'm yours."
A broken keening ripped out of his wide open mouth as Momo took his earlobe between her teeth and bit down. Not hard enough to draw blood, but hard enough to leave an indentation, for sure. The jolts that rocketed from his head to his toes felt like live wires of surging electricity - it was delicious agony and he needed her to keep doing it.
Then she slotted their mouths together, their first real kiss, and Ken's heart felt like it was about to leap out of his chest and start kissing her alongside him. Everything else faded away and she was so warm and soft, pressing multiple open mouthed kisses onto his lips and he was swept away. God, he could be kissed by her for the rest of his life and it wouldn't be enough.
Eventually she began firmly running her tongue over the seam of his mouth and he was utterly helpless to refuse her. Pleased rumbling started up in Momo's throat and migrated to his via their dancing tongues, she suckled on his bottom lip and he groaned like he was being flayed alive. His hands were clenched so tightly in her sweater that he was distantly sure he could feel the threads straining against his fingernails.
His brain was floating away and he was never going to get it back. There was only Momo, wrapped in his arms, her solid weight pinning him in place and rolling her hips and the bulge of her length teasingly into his. He could breathe nothing but her lips for the rest of his life, he could subsist solely upon her daring kisses and gentle touches and live forever. He was absolutely sure of it in that moment.
Lips desperately following hers as she pulled away, he whimpered pathetically, pleading for just one more dip of her mouth against his, but she chuckled and moved her lips instead down the column of his throat, sucking and nibbling as he kicked his legs out weakly beneath her, enamored with the path she was making.
Momo sucked hard on his scent gland and he yelped, bucking wildly up into her, then she moved her mouth to the juncture between his neck and shoulder, teasing her tongue across the skin and just barely dragging her sharp canines upon it. He tensed, anticipating the bite and arching his head to the side so she'd have all the room she needed to mark him, to make him hers forever… but she pulled back.
Ken stilled suddenly beneath her, embarrassed by his wanton behavior and with shame filled tears filling his eyes, he turned his head to stare blankly at the wall. Of course, marking him would be stupid. Tying herself to him forever would be stupid. They may have wanted each other right now, but that didn't mean she wanted him for the rest of her life. Mating was a big deal, a literal lifelong commitment… and being so disappointed by this was beyond dumb. Regardless of these facts, he was still pulled under into the darkness of self-loathing.
Soft hands danced on his face, wiping the tears away and pulling him back into view, her ruby pink eyes welded to his own and she uttered, so soft and pleading, "Okarun. I want it. I want you. I just need to make sure that it's what you want, too. I'll never do something that you don't want, I swear," Momo promised and placed a light kiss on each cheek, finally resting her forehead against his, both of them breathing in each other's scent.
Wild, hardy flowers drenched in the salty spray of the sea, and the smoky charcoal of a burned out campfire; cherished books and a sketch of a beautiful woman in pencil, surrounded by strong coffee. Adventure and refinement, each consuming the other in an endless whirl of affection.
Ken gurgled wetly, in a daze, nuzzling into her face and feeling so overcome with joy, "I do, Momo… please. I want to be yours, just yours - all yours. Please, alpha- Momo, please." He was fully aware that this was begging, but where he may have felt humiliated by thoughts like these before, now he only felt certain.
He was more sure of this than anything else in his life; Ken Takakura was meant to belong to Momo Ayase, and maybe she was meant to belong to him, too.
Momo sighed happily against his lips, pressing one lingering, deep kiss to his mouth before settling back in place above his neck. He squirmed, baring his throat in excitement and whimpering. When she bit down it hurt, as all the textbooks and classes on gender presentation and mating habits had assured that it would. But there was an accompanying rush of lightheaded warmth, flooding his nervous system and buzzing underneath his skin until he felt like he was glowing. Better than an orgasm, it ripped through his veins like a geyser. He was almost undone by it; the crush of liquid heat between his legs, the hot, hard pressure on his body… he was carried away by a current of warmth and overpowering sensation.
But Ken wound his way back along it lazily, coming to with Momo's hands running through his messy black hair, and her laving open mouthed kisses on her mark. His hands were resting on her hips, pulling her to him flush and tightly, maybe a little more demanding than an omega would normally be, but he was new to it, come on. And based on her groan above him, she liked it as much as he did.
She saw his eyes flutter open and his breathing caught as she giggled at the no-doubt starstruck look on his face, "My Okarun, " another kiss to the mark, "My omega," a lingering kiss with a little nip, "My… Ken Takakura." All the air left Ken in a harsh gasp at the sound of his name, his honest-to-god name, as she latched on to the mark and suckled, and his hands moved, one to fist in her glorious red-brown hair and the other to tug weakly at her sweater.
All this kissing was going to fucking kill him. Instinctively, he knew where it was all going to end up (thinking about that sent his mind into an overexcited tailspin), but the getting there has his brain melting from over stimulation, and his skin feels like it's smoldering and withering into a pile of ash under the blaze of Momo's desires. God help him, but he loves it.
Her nails are doing wonderful things to his scalp when she pulls off of him again, he whines loudly at the loss of her incredible heat and she clicks her tongue at him teasingly, pulling her pink sweater over her shoulders and dropping it next to his head. One of his hands finds it's way up to grab the fabric and push it into the edge of their nest, trying to secret it away before she tried to take it back or wash away her scent, but then he's struck dumb by the sight of her undoing her buttons and quickly shucking out of her school uniform shirt.
Seeing each other naked, even more so than they were currently, was nothing new to them. But the acknowledgment that this was on purpose, by no one's choice except their own, was heavy and powerful. Ken raised trembling hands up to rest on Momo's waist with the utmost reverence. She grinned down at him like always, confident and assured, as she reached behind herself to unclip her bra, breasts hanging free and nipples pebbling in the air.
Wondrously, Ken stared, taking in the brown of her areola and the way her breasts rested from this position, until she grabbed one of his hands and placed it upon her supple skin. Feeling the flush spread across his whole body, he squeezed, at her slight wince he nearly pulled back but her hand over his stopped him, "Gently," she whispered, demonstrating with her fingers on his.
It was such an addictive feeling, weighty and soft, but also firm. In his exploratory squeezing, slowly and lightly this time, his fingers caught on her taut nipples and she moaned and ground into him from above. A gasp escaped him and she lowered herself again to fuse her lips to his.
Lost in her kiss again, her tongue sweeping against his and their mingling breaths humid and desperate, Ken almost misses her hands reaching into the waistband of his drenched sleep pants. Once she wraps tender fingers around his straining cock though, his head falls back and the moan that rushes between his suddenly clenched teeth is insanely loud as he grinds up into the circle of her hand, whining. He knows he won't be able to come like this, at least not during his first heat, but it feels incredible and the fact that Momo is lovingly stroking one of the most sensitive parts of him leaves his insides puddling within him alongside the gathering slick.
Then she's released his mouth from hers and he's gasping for air as she pulls his sopping wet sleep pants and boxers off in one swift tug, wiggling cutely on top of him to shimmy the fabric down his legs and past her own.
Ken's penis is curved toward their faces, red and twitching, it's a weeping mess. He's always been kind of on the average size, but he's so excited right now he thinks he might pass out from blood loss alone as his cock twitches in time with his pounding heartbeat.
He's felt vulnerable with Momo before. They had nonsexual intimacy down to a science, at this point. But there was something profoundly important about this moment, and the ones that would follow. He was baring himself to her, willingly and wholeheartedly, and waiting to see if she would do so in return.
He was already hers; she'd already claimed him with her mark. The knowledge was instinctual - that she was his as much as he was hers, and nothing they revealed between them now with their bodies would ever change that.
Momo sat up and awkwardly pulled off her skirt and underwear (he almost asked her to leave it, but he so very much wanted to see all of her), and then they were a matching pair of naked, grinning, awestruck dorks. Their eyes skated over each other's skin greedily, hungrily taking in every scar gained from countless battles survived, every stretch mark from the years of abuse they've been putting their bodies through, and each blemish - adored for its uniqueness.
Ken wasn't sure who laughed first, or whether it was from nervous energy or sheer happiness, but soon they were both clutching each other's shoulders and cackling, both of their bodies shaking as they sucked in breaths between laughter. Momo rested her weight on her elbows and somehow found her way between his thighs, hovering over him and giggling into his shoulder. He pulled her closer with his legs and let out breathy chuckles against her lips instead, leaning up to capture her mouth once more.
The kiss turned fervent, both practically trying to crawl inside the other as she pressed the heavy shaft of her hard dick against his slick, it was slippery and hot as hell, and Ken was absolutely sure he was never going to recover from this kind of closeness with Momo. He wanted her more than breathing, he wanted her to live inside him, to have her children, to raise a family with him, and a million other things he didn't have the strength or courage to summon words for.
As her hand migrated down to the apex of his thighs again, his went gliding up her sides and onto her breasts, gently tweaking her nipples and kneading the tissue. Swallowing each other's moans as fingers plucked at flesh, Momo's digits were circling his entrance carefully, prodding teasingly through the slick mess. His own were twiddling absentmindedly upon her chest as he was inundated mentally with daydreams of some far flung future where he and Momo got to do this and so much more all the time.
Once two fingers pressed past the tight ring of muscle and inside of him, he pulled back and an overlong groan vibrated through his chest. Fuck that felt so good. If her fingers inside of him felt this good, he couldn't even imagine how insane her cock was going to feel. God, he wanted that so, so fucking much. He was pretty sure she could tell, because she was grinning before she leaned down to suck on her mark again and he was a whimpering pile of loose skin and barely connected muscle just waiting for her to take him over and mold him into whatever shape suited her best.
"Momo, god please, please alpha, I need more. Momo, please," more begging escaped him, and it clearly went straight to the woman's head because she carefully scissored her fingers inside him and ground her dick into his own. It was an aching bliss and he was barely holding on to himself.
"Okarun," she whispered eagerly, nuzzling her scent gland into his face, he practically purred as the strong smell of hydrangea and salt brought him back to the moment with her.
"Momo! Love you- need you so much. I love you so much," he panted against her lips, and he'd have been mortified by the slip if she hadn't immediately slammed her lips against his again, moaning so delightedly that it was impossible to miss even as dazzled as he was.
Another finger worked its way into his hole easily, the slick was effective and there was plenty of it, and she pulled off to press her forehead to his again and meet his eyes, "I love you too, Ken. I love you so fucking much."
A keening noise slipped out of his mouth in between gasps as she pumped her fingers into him gently; he knew he was ready, so fucking ready to receive her. He nodded at the unvoiced question in her eyes and whimpered as she pulled back just enough to adjust her angle, until the head of her dick bumped gently at his entrance. With one hand on her shaft as a guide and the other holding his face, their lips met and she pushed in simultaneously.
Ragged moans mixed together in their mouths, combining into a noise of hunger and unrepentant pleasure as she slid further inside him, inch by inch gliding softly into place until she bottomed out. Fuck, he felt so full, he didn't know what to do. There wasn't any pain really, the slick helped to prevent that, just a throbbing pressure, and an instinct to hold still and let his alpha take control.
Momo wasn't going to put up with that shit though, and hoisted his knees higher on her ample hips, still firmly seated inside of him - then she used her hands to guide him into small thrusts that took his breath away. She didn't increase the tempo or move on her own at all, even with his desperate whines and wriggling, until he took up the rhythm himself with his jerking hips - and then she sunk into him with abandon. And he was enraptured by their combined movements.
Every push and pull was an orchestra of sensation; the drag of her cock on his walls, the twitch of her member within him, the careful fingers wrapping around his own dick between them - all tender strokes and purposeful rolling of hips as they chased each other toward some distant finish line.
And the sounds were divine. When Ken was particularly taken by Momo's deep thrusts his muscles clenched, and the noises they made together were like a song, each responding and playing off the other's pleasure - pleased past any form of measurement.
Their scenting glands were pumping their essence into the air they breathed and it was heady, almost smothering themselves in each other. It was difficult to get enough air, but impossible not to take heaving gulps in between stolen kisses and love struck mumbles of adoration.
"God, you feel so good-"
"Please don't fucking stop-"
"Can't fucking stop, never stop-"
"Love you so much-"
They both uttered these phrases to each other, repeated as nauseam like feverish prayers, until they felt themselves approaching that cliff of bliss together. Ken felt Momo tensing her hips, preparing to pull out before she could knot him - to do the smart thing.
But all Ken could think about was the fact that they were adults and almost done with school, and Momo Ayase was going to be his alpha forever; so he whined into her mouth as he kissed her and urgently pulled her back into him, flush against him with his hands grasping her shoulders, twining his legs around her back and holding her firmly in place.
Maybe it was an omegan instinct, maybe Ken just really fucking loved her and wanted to have her many babies, or maybe it was some heady combination of the two. Either way, when her knot swelled and she climaxed, it all gathered inside of him, and the extended groan of her release made it obvious that there was nowhere else she'd rather have been.
Ken had been dancing along the edge as she toppled over, every pulse inside of him inching him ever closer, but it wasn't until she desperately stroked at his straining cock between them that he finally found his release. Fast and hard, spilling past her fingers and clamping on her twitching dick inside him until the black spots completely taking over his vision had faded. He may have cried out, but he honestly couldn't say for sure.
Gasping, covered in sweat, they clutched tightly to each other - their only anchors in this whirlpool of feelings that they found themselves in. Momo was stuck fast inside him, the knot fulfilling its purpose, and she pressed her lips to his with a breathy chuckle.
Then Momo wriggled, Ken moaned at the shifting feeling inside him, but she quieted him with a tender kiss on the cheek and then leaned down to put her lips next to his ear again, "Do you want to mark me, too, Okarun?"
His eyes were wide, and he knows she saw the wetness gathering because she grinned at him again, but there was no bite behind it. Leaning back down, still connected, Momo presented the junction of her neck to Ken. It wasn't unheard of for both members of a bonded pair to mark the other, but it was something incredibly intimate, in a place that would be in full view to the world, and culturally that was usually only done to the omega in these types of relationships.
Pressing an adoring, open mouthed kiss to her skin and sucking hard enough to leave a mark, delighting in her groans and tired wiggling, Ken finally sunk his teeth into her neck, and the moan that tore out of her mouth would stay locked in his brain forever. There was a small burst of coppery blood, but he laved it away with his tongue gently, scattering more little kisses around and upon his mark. Their lips met again and he felt complete, safe, and wanted.
Their relationship had never been normal. Ken knew that, he was sure Momo did as well. As he lay there underneath her, while she moved both hands up to run through his hair affectionately, pulling his mouth deeper into her kiss, he contemplated that maybe being her omega just made sense, in a weird way. Male omegas were rather rare, but so were female alphas. They'd been made for each other, whether by some quirk of biology or by fate, they'd found each other together here.
Ken sighed happily into Momo's skin when a totally different thought occurred, "Hey, Momo… how did you find out where I live, anyway?"
His alpha shifted and looked guiltily to the side, trying to avoid his eyes, "I may have kinda… broken into the school's directory."
"WHAT?!"
