Summary
     Sena was sure now that it had been simmering for hours, since maybe
     even the game. That the only reason he hadn’t become a panting,
     whimpering mess before now was the adrenaline and the pain of the
     game keeping it at bay. He never thought he’d thank Shin, Seijuuro
     for not pulling his punches.
Notes
See the end of the work for notes
The bookbag thudded to his bedroom floor, books and papers and pencils spilling
out, rolling over the floor, scattering like leaves. But his palms stayed flat
against the door, chest heaving, and his eyes shuttered closed. It was drowning
him, this strange too-hot heat that licked at his skin from the inside. Breaths
were jagged pants and sweat slid down his temple, down the back of his neck,
tickling along his spine. A low, needy whine hissed past his teeth.
Sena was sure now that it had been simmering for hours, since maybe even the
game. That the only reason he hadn’t become a panting, whimpering mess before
now was the adrenaline and the pain of the game keeping it at bay. He never
thought he’d thank Shin, Seijuuro for not pulling his punches. The Oujou Knight
flashed through his mind at the thought and he let out an honest-to-goodness
moan, a sound he’d not even made the first time he figured out what his dick
was for. He hadn’t popped a knot or gotten slicked before, but eh, dicks were
dicks even before presenting.
P-presenting…
Horror fluttered over Sena’s face as his hand scrabbled at his belt and pants
button. It was right around the right age. And… and at the school; he hadn’t
even taken a shower once they’d gotten back to Deimon. He’d already felt like
his skin was too tight and his clothes were rubbing his nerves endings raw. The
smell of his teammates, the beta and alpha pheromones, even Mamori’s sweet,
motherly Alpha scent he’d always been so weak to, had been disgusting. He had
mainly run straight home to escape the smell of them, the odor that had coated
the back of his throat and made him want to gag. None of them had smelled…
right. The idea of touching them, or them touching him, in any way, even
accidentally, had made him jittery and anxious.
His green slacks sagged around his bony hips and, with eyes clenched shut, he
reached down and gripped himself. The effect was almost instantaneous, his
whole body doubling over as he cried out harshly, but quietly (he’d always been
quiet). His eyes were wide, so wide they burned and teared up, but he knew
immediately that it wasn’t enough. As good as his hand on his cock felt, he
already felt… empty. Something hot slid through him like a knife, making him
whimper and his grip tighten. Slowly, so fucking slowly, Sena braced one hand
against the wall and moved his hand out of the front of his pants. Teeth cut
into his bottom lip and an internal mantra played out in his head uselessly,
please not omega please not omega please not omega, it just… it wouldn’t be
fair. After all these years, of running and being beat down, of taunts in his
ear of how weak he is, how he’s obviously an omega, how he’s born to be
someone’s bitch, he finally, finally chose to do something strong. He chose to
stay on his feet and run. He won today, damn it! He WON. Against Shin Seijuuro.
But his fingers pressed between his cheeks and he gasped aloud, eyes popping
open and eyes glowing a gold he couldn’t actually see.
Because against his fingertips is a slick wetness that makes it all too easy to
press inside.
“Nonononono,” he wheezed, fighting back tears. He fell to his knees, palm
slapping to the floor and his face pressed to the edge of the rug. There was a
pencil under his hand and a book under one knee, and he was pretty sure there’s
another book pressing into his forehead, but all he could focus on was the way
his fingers sink deeper and how it’s not enough and no no no anything but
omega.
He stayed kneeling and shaking on the ground until it physically hurt; trudged
down to confess to his parents long after the sun has set. It still hadn’t been
long enough to want to face it yet.
…
“Omega! Oh, Sena-kun! This is wonderful! I just knew you’d present this year.
How are you feeling? You’re not in heat, right? You really shouldn’t be in
school, Sena-kun, your first heat will be any day now, you know? You’re okay,
though?” Mamori motherhenned, cool hands pressing to his admittedly warm
cheeks. He’d always run a little cold, though, so he probably just wasn’t used
to it. Her pretty blue eyes flashed scarlet in her worry and he couldn’t help
but flash his shiny new gold back.
“I’m fine, Mamori-neechan. Really. I went to the doctor this morning. Hiruma-
san said I had to go meet at the clubhouse this afternoon. I don’t want to make
him angry.” Ever. Sena shuddered just thinking of it.
Mamori set her fists on her hips and scowled. “You’re the secretary. You can
take a day off while the spring tournament is over. Presenting is very
important! You should have taken a rest day,” she scolded.
With his hormones already a cocktail thanks to his new presentation, having an
Alpha scold him, in public (okay, so in the hallway, no one is even paying them
any attention except for a few absent sniffs in his direction) made Sena
cringe. Embarrassingly, a whine slipped past his gritted teeth and Mamori
immediately looked contrite.
“Oh, Sena-kun, I’m sorry.” Her warm, soft hands fell on his shoulders and she
rubbed her even softer cheek against his, scenting him affectionately. Instead
of calming him down, as it always had in the past, Sena’s back went up.
He was halfway down the corridor, eyes glowing gold and chest heaving, before
he even registered the action. Her scent was already on him though, thick and
heavy and sweet and it wasn’t right.
“Sena-kun?”
“I gotta go!” Sena wrenched out painfully. He hightailed it away, papers and
clothing fluttering in his wake. Mamori frowned in his direction.
“Ah! His lunchbox and umbrella! I’ll give them to his class rep. I’d hate to
push him,” Mamori sighed softly.
Luckily (?!!?) Hiruma gave two-to-zero shits about omegas or alphas (being a
beta probably helped there, but Sena had a feeling that even if Hiruma was an
omega, he’d be exactly the same). Kurita tried to point out there was
technically a restriction on omegas playing rough contact sports, but Hiruma
just waved a negligent hand and said he’d handle it. The envelope of pictures,
along with Hiruma’s brusque instructions, were shoved into Sena’s hands and he
went up to his classroom to do as asked. It had been such a relief to sink back
into the memories of the game, remembering the roar of the crowd and the beat
of the ground beneath his cleats. It… it was over… he realized slowly. All of
it over. And he’d just started. Even if Hiruma got permission for Sena to play
(which he probably would, there really wasn’t a question), it didn’t change the
fact it was over. The pictures blurred and wobbled in his vision as tears
streamed down his face. He wanted to blame it on his new omega…ness, but he
knew that wasn’t true. He… he missed it. And it’d only been a few days, just
two games. He lifted the envelope again to put the useful ones back in, when…
The last picture fluttered to his desktop.
Sniffling and rubbing at his eyes with one arm, he lifted it up to see. The
picture shivered and it took way too long for Sena to realize it was his hand
that was shaking.
Shin.
His scowling face was mostly hidden by the helmet he wore, and his brows were
low in an obvious concentrated frown, but… Shin. It repeated in his head over
and over, that weak, quivery heat building in the pit of his stomach once more
as a few more tears slipped down his cheeks.
The door kicked open with a crash and Sena squeaked and jumped, butt leaving
the chair, as Hiruma and Kurita sauntered in. As they discussed amefuto, Sena
discreetly slipped the photo in his inner jacket pocket.
...
It was still in his pocket, hot against his ribcage, when he stood in the rain
and stared down at the rope ladder lying forgotten in the mud. His palm pressed
to it, feeling it bend and warp to his side. Shin was probably right now
training. Practicing for his next game, his eyes on the goal of the Christmas
Bowl. Where he would be waiting for Sena. His umbrella clicked shut and dropped
to the ground.
Mud caked his skin, his clothes, dragged down his legs until he could barely
lift them. It had been dark when he’d started, but now it was almost pitch
black. His mother would worry soon, and his father, too. Especially now he was
officially an omega (like everyone else, they hadn’t been surprised, merely
excited and happy for him). He bent over, hands clasped on his knees, as he
caught his breath. He’d hoped that running himself ragged would accomplish two
things- 1) improve his movement and speed, and 2) distract him from the fever
that had been a low-grade burn for days. Clawing at his tie to loosen it- why
was he still wearing it?- he snagged up the ladder and began to roll it up.
“Eyeshield.”
It fell with a clatter and squishy-sounding thud. Okay, he’d definitely been
out here too long. He was hearing things. No way was-
“Eyeshield 21.”
His shoe squelched as he turned to see what had to be impossible. No way was
Shin, Oujou Knight, at Deimon High. No way was he just standing in there in the
rain, looking just as flushed and out of breath as Sena felt. Shin strode
towards him, face set in angry-looking lines and Sena backpedaled, arms
pinwheeling.
“Hiiiii, this is a hallucination. My hormone-addled brain is making you up,
you’re totally not here right now but oh my god, please don’t kill me!?” he
shrieked, hands clenching into fists as his eyes slammed shut. He leaned back,
almost right off his feet onto his ass, but Shin’s hand were gripping his
elbows and his face was pressed to Sena’s neck. To where his pulse beat too
fast. Where his scent was strongest.
“Eyeshield.I knew it.”
“Kn-knew w-what?” Sena chattered. Before, he’d been numb to the rain, but with
Shin’s body so close and so hot, everywhere Shin wasn’t touching felt icy.
Shin leaned back, one hand grasping Sena’s chin to force his face up. Sena’s
eyes fluttered open, lashes heavy with rain and some weird lethargy. Without a
word, Shin’s eyes flashed red.
“Ho-Holy- what the hell!?” Sena squawked, tugging away. Well, trying to, Shin’s
hands were like iron. “What are you- this is a nightmare! Wake up, wake up,
Sena!” he pleaded desperately, eyes snapping shut again.
“Sena.”
The sound of his name, not Eyeshield, coming from Shin’s mouth had shudders
racing down Sena’s spine. That same hot need from the game day churned in his
gut, slicing through him like a white-hot wire.
“Oh my god, oh my god, oh my god,” Sena wheezed. It was cold out, it was still
raining, but he was hot all over. Too hot. His clothes clung too tightly and
felt almost like heavy slime on his sensitive flesh.
“It happened right after the game. I couldn’t… I couldn’t think. I just knew I
needed to find you,” Shin was saying, words a low raspy sound.
“You… you presented, too?” Sena asked, the words punched out of him. His wide
eyes tracked Shin’s face and the older student nodded. “B-But… you’re… you’re a
second year. You…”
Shin shrugged. “It’s not the same for everyone.” His eyes flashed red again,
following Sena’s tongue when he unconscious licked his lips.
“We g-gotta… you g-gotta l-let me go,” Sena whispered. Shin’s hands convulsed.
“I… I think…”
Shin nodded, knowing exactly what Sena was about to say. He’d obviously been
feeling it, too. The build-up of tension thickening between them. But Sena was
already swaying closer, eyes slipping half-closed, nose pressing to the center
of Shin’s chest. Alpha. Everyone had smelt so bad, so wrong. He shuffled
closer, rubbing his cheek against the rapid thudding of Shin’s heart.
“H-Heat. I sh-shouldn’t have come here,” Shin rasped even as his arms wrapped
around Sena’s smaller, slighter frame.
“Mhm,” Sena hummed, drugged on Shin’s scent and heat. “B-Bad idea. T-take me
home, alpha,” the first year slurred, hands grasping the tails of Shin’s white
coat. Those… those weren’t the right words... that wasn’t what he meant to say.
Why was it a bad idea? Why…?
“Eyesh- S-Sena, I…don’t even know your name,” Shin growled, shaking his head to
clear away the fog.
“Kobayakawa, Sena. I’m a first year,” Sena mumbled, using his grip on Shin’s
top to push up on his toes and press his cold, damp nose to Shin’s collarbone.
This time, Shin shuddered, a low grumbling-sounding groan torn free. Slick slid
down his inner thighs. Sena was already soaked from rain and mud, he shouldn’t
be able to tell, but it was so hot and everything else was so cold. “Alpha,
alpha, please.” There was definitely something wrong here. He didn’t even know
what he was asking for. But his alpha was right there. His alpha that had
presented forSena. What was wrong again? “My alpha,” Sena stated out loud, eyes
flashing gold under his lashes before he bit Shin’s collarbone.
Shin literally snarled as he lifted Sena right off his feet.
“Oh my god!” Sena shrieked, then laughed brightly and a little crazed from
where he hung over one of Shin’s shoulders. “You’re sure you’re a s-second
year? You’re kinda b-big,” Sena muttered, hand smoothing down the line of
Shin’s spine.
He stumbled, quickly setting one large hand over Sena’s ass to hold him in
place. The omega's eyes rolled to the back of his head, body strung tight.
“Have to find…out of the rain,” Shin was muttering.
Hm, outta the rain. Yes, that sounds good. Very very good. Sena gripped the
soaking wet cloth in both fists and waited patiently. Well, he was kinda
squirming, but Shin’s hand was on his butt, okay? It was so close to where he
needed. He thought he felt empty before, but now? Sena wanted to sob he felt so
desperate.
Some door squealed open, and Sena reared up, eyes blinking rapidly in the even
darker… wherever. Vertigo overtook him before his back hit thick padding. To
one side, he saw a net bag full of soccer balls and to the other, bright,
orange cones. The door had been left open and Sena gaped up at Shin as the
second-year yanked his shirts off, the dim light of streetlamps etching Shin’s
probably perfect body in pale yellow. He was only thinking probably because
omega-brain most likely was painting Sena's bias... but that was stupid. Shin
was definitely perfect. Sena was so busy staring, mouth dry, it took him until
Shin’s hands reached for his tie- why was that still on!?- to get on board.
And then he got very on board. “I-I got this,” he rushed to assure Shin,
tearing it over his head and then attacking his buttons. There was a soft huff,
but Shin was leaning down, nosing at Sena’s throat, as his hands worked at his
pants. “Oh my god, is this even real? Are you really here?” Sena asked, crowing
happily when his shirt was thrown aside and his arms wrapped around Shin’s damp
shoulders.
“Yes.”
Shivers followed that simple, single syllable reply.
“Yes, yes, yes, I needed you. This whole time. Everyone else smelled so bad,”
Sena breathed out in relief, rubbing his slack mouth against Shin’s throat.
Hands gripped at his pants, tightening to bruising, but Sena merely wriggled
eagerly, pressing into his fingertips. He wanted Shin’s marks all over him.
“I’m here. I won’t go,” Shin promised as he lowered Sena down to the mats. Sena
blinked sluggishly up at Shin hovering over him and smiled, slow and satisfied.
“Good.” He tangled his fingers in Shin’s dripping hair and tugged him down.
Their mouths connected, awkward and off-angled. But they both moaned into it,
tongues sweeping over lips and thrusting inexpertly into their mouths. Sena
mapped the shape of Shin’s mouth, then bite at his bottom lip, pulling it
between his teeth to suck. He loved the plush feel of Shin’s lip trapped in his
mouth, the bruised puffiness soothed under his tongue. Distracting tugs at his
hips had him whining, but arching up. His belly burned at the exercise, so he
kissed Shin harder, mouth slanted and slick, too wide and too much teeth.
Chilled bare skin pimpled with goosebumps as hands trailed up Sena’s legs.
Naked, he thought distantly, I’m naked. He gasped into Shin’s mouth, hips
thrusting up.
“Sh-Shin? Shin, I…” Sena whimpered, frowning in confusion.
“I… I don’t…” Shin pulled away enough to stare down at him. His eyes were blown
wide open, mouth parted, and skin flushed pink. At the same time, he looked
lost and just as baffled as Sena. With a start, Sena realized Shin hadn’t done
this before. His handsome, beautiful alpha was an alpha because of Sena, just
like Sena had presented because of Shin. A part of him had figured that Shin
must’ve done… something, he was older and handsome and built like a brickhouse,
surely he had some experience? But if the look on his face was any indication,
he was as virginal as Sena.
Sena chewed on his battered lip, frowning and perplexed. Well, from everything
he’d ever heard or seen, he should… Yeah. He wiggled and tried to turn onto his
belly, because that was what he was supposed to do, right? Belly down and
present?
But panic skittered over Shin’s features and he pinned Sena’s wrists to the
padding, still flat on his back.
“Wh-What?” Sena gasped. Something ugly and sick had him wanting to curl away.
“You d-don’t wa-want-”
“No! Yes, just not like that. I have to… I have to see your face,” Shin said,
that edge of panic making his eyes bleed red around the edges.
“O-Ohkay,” Sena agreed, nodding and blushing slightly. It would’ve been less
embarrassing the other way, but… “You… your fingers,” he whispered, hips
squirming at the thought.
Shin frowned, red-tinted eyes squinting. Sena blushed even brighter and glanced
to the side.
“I-In me,please, Shin-san?”
“Seijuuro,” he grunted, but he looked down.
One hand released Sena’s wrist and flattened over his sternum. With a bracing
gulp and mostly fueled by need, Sena grabbed Shin’s wrist and shoved his hand
down. His belly quivered and twitched under the dragging pressure of Shin’s
palm and fingers, until, finally, the linebacker reached down low enough to
slip down to where he was wet and aching. Sena’s fingers clenched around Shin’s
wrist as his hips stuttered up, shoving onto the pads of Shins’ fingertips.
He could feel his lips moving, and distantly, he could hear himself repeating
the same words over and over, just pleaseand yes tumbling together into
incoherence. When Shin’s finger breached him, slid into the hot slick heat of
him, Sena’s body went taut and breath caught. He barely even noticed Shin’s
mouth sliding down the same path his hand had taken, too wrapped up in the
feeling of being filled, even a little. His hips moved up and down, effectively
fucking himself on Shin’s finger, already whining wordlessly because he needed
more, now. A shock of hot wet on his cock had him bracing on an elbow- when had
Shin let go of his other wrist?- and looking down in a daze. Shin was frowning
down at the dark, angry-red erection lying over Sena’s belly, pre-cum already
pooling in the smooth dip.
“Y-You d-don’t have t-to,” Sena tried to protest. Honestly, the last thing he
was worried about right now was his dick, not when there was only one finger in
him and it wasn’t moving, damn it. Shin glanced up at him, then, keeping eye
contact, leaned down to lick at the clear fluid on Sena's skin. “O-Oh my god,”
Sena exhaled. Those dark eyes flashed scarlet before shuttering closed to lap
up every bit of it. “Sh- S-Seijuuro.”
His fingers tangled in Shin’s wet hair before he fell back, his other hand
falling over his eyes. Gasps were hitching out of him in time with his hips
moving, with Shin’s hand moving at last, while his tongue slid over Sena’s too-
flushed skin. The tongue lowered, following the line of his hipbone, then down
to the pit of his groin was he knew scent was strongest, even stronger than at
his neck or wrists. His legs automatically hooked over Shin’s shoulders, crying
out sharply as a second finger slipped inside.
“Yes, yes, Sei-Seijuuro, moremoreplease, it’s good,please, I need-” Sena
pleaded while his hips moved faster, even though it hurt a little, too fast,
too much, too soon.
Hot breath fanned over his inner thigh, his sac, and lips pressed to his taint.
“S-Sei? Wha-what’reyoodoing?” Sena slurred.
“You’re moving too fast. It’s going to hurt,” was Shin’s concerned reply. The
worry had Sena smiling dopily under the cover his hand. His alpha already cared
about him, about his pain.
“I’m good, it’s so good, I promise, please, I need you,” Sena assured him,
pressing down his hips so Shin’s fingers sunk in all the way to his palm. He
groaned at the feel of it, the fingertips brushing against something inside him
that had sparks bouncing behind his eyelids. There was a deep rumbling, that
made Sena think of Pitt purring, and a breath later, a mouth pressed to his
hole.
Sena blinked wide teary eyes at the roof of the equipment shed they were in. It
was too dark to make out details, but Sena wasn’t looking anyway. His entire
being was focused on the hesitant, gently lapping tongue at his hole. A tongue
was sliding between fingers, prodding at the stretched out muscle, thrusting
into him in a parody of what Sena needed. His breaths were panicky-fast, but
nothing about him was anxious. His spine bowed, fingers twisting in Shin’s hair
between his legs, body shaking apart as he cried out Shin’s name. Babbling and
pressing towards Shin’s mouth only to wriggle away, undone and overwhelmed,
pressing down again for more. Tears were leaking from the corners of his ears,
tickling his ears as it soaked into his hair.
“S-Sei-SeiSei,” Sena gasped on a sob. Screamed as a third finger worked its way
in to spread him open wider than he’d ever been.
When he came to, the white in his vision fading into normal colors, Shin was
hovering over him, looking this-side-of terrified. Drunkenly, Sena reached up
to touch the sharp planes of his face, thumb brushing over glistening lips.
“Kn-Knot me,” he murmured, wobbly legs curling over Shin’s. His eyes flashed
gold to Shin’s red as he smiled stupidly. He felt sopping wet and his skin was
covered in sweat and cum up to his chest, but he wasn’t done. He was still too
hot and Shin’s fingers were thankfully still in him, but he needed more. “Sei,
Sei,” he breathed, cupping the back of his head and yanking him down.
He tasted himself on Shin’s mouth, his tongue, but Shin’s taste was like
another hit of a drug. The groan that flooded his mouth as Shin’s cock skidded
over his sticky stomach even sweeter.
“Knot me, knot me, Seijuuro, hurryhurryplease” he begged, wriggling and finding
enough strength to lock one leg around Shin’s waist and pressed his heel into
Shin’s lower back.
“Yeah, yeah, I just…” his hands slipped over Sena’s hips, shaking and slick,
shaking harder when Sena whined at the loss of his fingers in him. “I know, I
know, I’m sorry,” Shin panted, forehead pressed to Sena’s, eyes downcast to
watch himself.
Sena breath caught, anticipation and want freezing him in place. Shin shook too
much the first time, slipping over Sena’s entrance to between his cheeks. But
he took a deep steadying breath and slowly pushed in the second time. The
guttural sound that left his mouth sounded pained, but he was still pushing in
gradually, hips working. Sena clutched at Shin’s back, eyes clenched shut and
nails digging, cutting, into skin, only relaxing when Shin was seated fully
inside.
“Ohgodalphamyalphaohgodohgod,” Sena rambled breathlessly, trying to wriggle up,
but Shin’s shaking arms wrapped around his waist and pinned Sena down with his
weight.
“Don’t. Don’t move.”
“Seijuuro,” Sena whined, nosing at Shin’s throat, placing tiny, fleeting kisses
on his sweaty kiss.
“Just don’t. Sena, you’re… you’re so hot and tight, I can’t- I’d knot you right
now,” Shin hissed past gritted teeth. Sena blinked and leaned back far enough
to see Shin’s face, twisted up and pained, teeth actually bared.
Sena set his palms on each side of Shin’s face and waited for his eyes to open,
startled and crimson. Sena smiled softly, the smile growing wider as the red
bled away to dark, dark brown, black in this tiny shed behind Deimon High while
it still poured buckets outside. He cupped the back of Shin’s head and pulled
him down into another kiss, this time soft and slow, so slow, as his hips
moved.
They gasped together at the feeling- the sweet drag and the instinctive
tightening of Sena around Shin, scared of being empty. But Shin was already
thrusting back in, again and again, their mouths slack and gasping, sweaty and
rain-soaked hair falling into their eyes. Sena couldn’t quite get the rhythm,
their hips just a little off, but he couldn’t bring himself to care. The feel
of Shin’s cock filling him up, never completely leaving him, had the sobs back,
fever-flush spreading from his crown to his toes. He was so so close. He’d
already come, but his was ready to go again, ready to come when he was full.
Whispered encouragements fell from him mouth, egging Shin faster, harder, until
his hips slammed against Sena’s butt, the slap of skin on skin, the squelch of
slick, obscene and gross and so so very very perfect.
The tug on his rim had his eyes glowing gold and he turned his face away. He
couldn’t- he couldn’t stop the heightened cries, but he could muffle them with
the mat, his own shoulder.
“Sena, Sena, look at me,” Shin demanded hoarsely, but it sounding like a plea.
Sena stared up at him without thinking, mouth gaping red and damp and bruised,
eyes glowing.
Their eyes stayed locked, red eyes on gold, as the knot swelled up hard and
fast and tied them together. They moaned, eyes fluttering but not closing, as
Sena tightened around him, better than anything Shin could’ve imagined and as
the thick ball of flesh pressed right up against Sena’s prostate in a way
Shin’s cock had missed. Shin ground his hips down, just to feel that tightness
again, and that was all it took for Sena to shatter apart a second time. Shin
collapsed, chest heaving and mouth on Sena’s throat, hips undulating lazily as
he continued to spill into the wet clutch of Sena’s body.
Sena fell asleep with his fingers still stroking Shin’s back soothingly.
 
…
Sena woke up feeling sticky, hot, and achy. Also, like he’d run 16 km without
stopping and then fallen under a block of concrete. A really heavy, breathing,
sweaty-skinned block of concrete. That smelled really good.
“Hiiii?!” Sena shrieked, scrambling to push the weight away. Only to squawk in
outraged pain as something pulled at his-his…
His wide, dilated eyes met the sluggishly blinking gaze of one Shin, Seijuuro,
ex-block of concrete and Sena knew- this is what hell was.
He’d thrown himself on Shin Seijuuro. He’d set his newly-omega-slicked ass
right in Shin’s hands and then- oh god, he’d kicked Shin’s ass into knotting
him!? He very clearly remembered digging a heel into Shin’s back for going too
slow.
“Oh, oh my god,” Sena gasped in horror, hands over his flushed face. “I’m
sorry. I’m so sorry. I didn’t- Mamori-neechan warned me- but I said I was fine.
I-I just- one whiff of you and just jumped you and I’m so so sorry!” Sena
rattled on, sick to his stomach with humiliation.
Hands gently pulled Sena’s away from his face and he met Shin’s eyes
reluctantly. The older alpha frowned in confusion, but his thumbs were rubbing
soothing circles into the thin skin of Sena’s wrists.
“It was me, too. I shouldn’t have come here. I should’ve waited until after my
rut had passed, but I thought I had it under control. I didn’t realize… I was
just waiting for you,” Shin admitted. Shame darkened his frown, and genuine
concern as well. “This is my fault.”
“No! It’s… it’s both of us, right? How about that?” Sena compromised with a
tremulous smile. “I… I barely even know you and I hate to see you sad,” he
added in an amazed whisper, eyes tracing every line and angle of Shin’s face.
A face that shuttered closed and scowled. “I will take full responsibility of
the consequences.”
Sena tilted his head. “Consequences?”
Shin’s swallow clicked loudly before his gaze darted down to where they were
still connected.
“Oh! You mean!” Sena’s eyes widened in understanding. “It’s okay! I mean,
there’s still a chance, but it’s our first heat… er, rut? And I took a shot. It
wasn’t a blocker, because they recommend not blocking the first one, but I did
take a birth control shot. Oh- oh thank god!” Sena pressed both hands to his
thundering chest. “Oh thank god I went to the doctor this morning. I told my
mom I didn’t want to, I didn’t feel that bad, but she insisted. I need to buy
her flowers or something.”
A quiet snort had Sena looked up in time to see Shin pressed his face to Sena’s
shoulder and laugh, body shaking, as much with humor as with relief.
“I… I’ll buy her a flower store.”
Sena laughed, too. “Wow, that was so stupid. We could’ve, wow, we could've
screwed up a lot.” It really wasn’t that funny, but he couldn’t stop laughing.
“Wh-what time is it, anyway? It was late…?”
“Ten.”
“TEN?!” Sena shrieked, shoving up on to his hands. They both winced, but Shin
had shrunk enough to slip free this time. Which made Sena wince and grimace for
an entirely different reason. “Oh, that’s… that’s a new feeling,” he muttered
diplomatically while the mix of cum and slick trailed down his thighs.
Shin grunted and cast around for his soaking wet undershirt. It was better than
nothing, though. Sena blushed, but cleaned up the best he could while Shin
watched, nostrils flared and eyes red.
“This is kinda gross,” Sena pointed out as he balled it up.
“If you say so,” Shin shrugged. “I should take you home. I…” He gazed at Sena,
eyes a little too wide, and Sena remembered like a jolt the same expression
from before. Of looking lost.
“And we’ll talk tomorrow? Talk-talk, not… this,” he suggested gently.
Shin nodded, but raked his gaze up and down Sena’s still naked body. “Probably
advisable.” He sounded distinctly put out.
Something like smug triumph at Shin’s obvious interest in him, had Sena
fighting back the urge to preen. That’d just be distasteful really.
“D-Does… Does this mean we’re d-dating?” Sena asked, drawing up his legs
slightly for covering, fingers fidgeting restlessly.
“I believe that’s the least of it,” Shin said dryly. Sena dropped his forehead
to his knees and laughed again.
