Stiles smiled, snuggling deeper into Derek’s side, the alpha’s scent wrapping around him like a warm blanket. It was comforting—thick, familiar, grounding.
He hadn’t been feeling great all day. No fever or obvious signs of sickness—just bone-deep tiredness and an insatiable craving for sweets.
Which is why they were now curled up on the couch, Derek’s arm wrapped securely around his waist, their legs tangled beneath the blanket.
Everything felt perfect.
Stiles’ eyes drooped, heavy-lidded as he blinked slowly, drifting in and out of sleep while the TV droned on in the background.
He shifted slightly—and then stilled.
Something felt… wet.
Panic bloomed in his chest. Had he—? Had he peed himself while dozing?
Mortified, his face flushed hot. He gently pulled back from Derek.
“I’ll be right back,” Stiles mumbled, slipping out from under the blanket and off the couch.
“Okay, kitten,” Derek murmured, flashing him a warm smile that made Stiles’ insides flutter despite his embarrassment.
He padded quickly to the downstairs bathroom, quietly closing the door behind him.
The wet sensation was spreading, and with fumbling hands, he yanked down his pants and sat on the toilet.
But it wasn’t what he thought.
Frowning in confusion, Stiles touched the fluid that had soaked through his underwear. It was clear and slick—definitely not pee.
Almost like come… but not.
He sniffed it. The scent wasn’t unpleasant—musky, but also faintly sweet?
A sharp cramp twisted in his stomach, making him wince. Maybe he was getting sick.
He grabbed some toilet paper to clean up, but the wiping seemed never-ending. It was coming from his butt, which only deepened his confusion.
And worse—it wasn’t stopping.
In fact, it seemed to be getting worse.
It was almost like he was going into heat or something.
The thought sent a cold chill down his spine as everything clicked into place.
Stiles’ heart raced. He glanced nervously at the door separating him from Derek.
He’d been waiting for this day—his first heat. He’d known Derek would fully claim him then. He wanted that.
But now that it was here, anxiety surged through him like a wave. His fingers lifted to the side of his neck, pressing gently against the skin.
There was nothing there yet, but he could feel it beginning—the mating gland forming. The skin was tender, overly sensitive.
He sucked in a sharp, almost panicked breath, his heartbeat pounding against his ribs. Curling in on himself atop the toilet, he fought to stay grounded.
Derek was going to claim him.
Derek was going to fuck him.
Derek was going to breed him.
His chest rose and fell in rapid, shallow breaths, edging toward a panic attack.
He’d been ready. He’d planned for this. But now?
He felt unprepared.
He felt scared.
A sudden, heavy knock jolted him from his spiraling thoughts.
“Stiles?”
Derek.
Stiles’ throat bobbed as he swallowed. “Y-yeah?”
“Is everything okay?” Derek asked, and Stiles froze in horror as the doorknob began to turn.
“Don’t come in!” he yelped, voice tight with panic as he scrambled off the toilet, nearly toppling over with his pants tangled around his ankles.
“Everything’s fine!” he added in a high, squeaky voice, hastily kicking off his pants and pressing his side against the door.
There was a heavy pause on the other side. Stiles stared at the wood, silently begging the alpha to just go away.
His eyes dropped to the lock. It wasn’t great. Would it even hold against an alpha werewolf?
Unlikely.
“Kitten,” Derek murmured, his voice low and soothing.
Stiles whimpered, guilt twisting in his gut as more fluid slicked down his thighs, his body betraying him.
“What’s the matter?” Derek asked, concern evident in his tone—and that only made Stiles feel worse for being afraid.
“I’m scared,” Stiles whispered, barely a breath. But he knew Derek would hear him.
“Why are you scared?”
Stiles inhaled shakily. “I’m wet.”
“You’re wet?” Derek repeated, clearly confused.
“Yeah…” Stiles bit his lower lip. “Back there.”
“Back ther—oh.”
Silence fell heavy, the only sound in the bathroom was Stiles’ uneven breathing.
"Kitten,” Derek murmured, “open the door.”
Stiles whimpered, fingers trembling as he turned the knob and slowly cracked the door open.
He tugged his t-shirt down, instinctively trying to hide his nudity from the alpha’s gaze.
Derek’s eyes flashed red, nostrils flaring as he took in the scent—while Stiles fidgeted, staring at the floor in shame.
“It’s going to be okay. I’ll take care of you,” Derek said gently, holding out a hand.
Stiles peeked up at it, then hesitantly stepped forward and laced their fingers together.
“I’d never hurt you, kitten,” Derek whispered, pressing a soft kiss to Stiles’ hair.
“I know,” Stiles whispered back, closing his eyes as he breathed in the comforting, heady scent of Derek’s alpha musk. “I’m just… nervous, I guess.”
He winced as another cramp rolled through his stomach.
Derek noticed immediately, one hand rising to cup the back of Stiles’ neck. The touch was grounding, and Stiles melted into his chest with a quiet exhale.
“Come on, kitten,” Derek rumbled, his thumb stroking over the sensitive skin at Stiles’ neck. “Let’s get you to bed.”
“Okay,” Stiles sighed, tilting his chin up to meet Derek’s gaze before allowing the alpha to guide him upstairs.
Stiles’ insides were in a nervous tizzy as they stepped into the alpha’s bedroom. Derek’s musk was especially potent here, and Stiles found himself panting, the thick pheromones almost tangible on his tongue.
He immediately moved toward the bed, crawling up onto it and face-planting into the comforter with a sigh of contentment.
From behind, he could hear Derek shuffling around the room—the soft thump of his footsteps, the closet door creaking open and closed, then retreating to the bathroom where the sound of running water filled the air.
Stiles was curious what Derek was doing, but he couldn’t bring himself to move. The scent on the sheets had him spellbound. He buried his face deeper, inhaling the musk-soaked fabric. If he breathed deeply enough, he swore he could even smell traces of Derek’s come.
His mouth watered, and he whimpered when a sharp cramp twisted through his gut. He rolled onto his side, curling into a tight ball.
“Derek—” he whined, flinching slightly when the alpha appeared beside him, gently pressing a cold, damp cloth to his forehead.
“Shh,” Derek soothed, running a hand through Stiles’ hair. His other hand slipped beneath Stiles’ shirt, drawing slow circles across his lower stomach. “You’re flowering, kitten. Your body’s preparing to carry my pups.”
Stiles squirmed at the words, Derek’s touch both uncomfortable and relieving all at once.
“It hurts,” he whispered, eyes flicking up to meet Derek’s.
“Do you want me to help you feel better?” Derek asked, his voice a deep, soothing rumble that made Stiles’ stomach flutter. “I can ease the cramping.”
“Yes, Alpha, please,” Stiles whimpered.
“Okay, kitten,” Derek said with a soft smile, climbing onto the bed behind him. “Roll onto your back for me.”
Stiles didn’t want to move, but the promise of relief was too tempting to resist. He shifted slowly, settling onto his back.
Derek’s large, cool hands guided Stiles’ thighs up and apart. Stiles flushed, knowing the alpha could see everything like this. He instinctively tried to close his legs, but Derek’s grip was unyielding.
“Derek—”
“Shh. You’re beautiful, kitten,” Derek murmured, leaning down to nuzzle against a pale thigh. “There’s nothing to be ashamed of. Nothing to hide from me.”
“What are you doing?” Stiles whispered, wide-eyed as Derek nosed his way lower, past his smooth, hairless balls, to where he was leaking slick.
The first swipe of Derek’s tongue startled him. Stiles gasped, his thighs jerking in Derek’s hands.
“Derek?” he whimpered, voice shaky, as the alpha’s tongue became relentless in its pursuit to taste him.
Derek growled, nose pressing against Stiles’ balls as he devoured him, drinking down the slick like it was his favorite meal.
Stiles panted, heat coiling tight in his belly as Derek’s tongue pressed just past the sensitive rim.
“Alpha,” he moaned, hips squirming in small, jerky movements, unsure whether to move closer or away—it felt so weird, but so good. He wanted more.
But then Derek pulled away, leaving him suddenly empty. Stiles collapsed onto the bed like a puppet with its strings cut, breathless and dazed.
He blinked up just as Derek leaned over him, Stiles’ thighs now bracketing Derek’s hips.
“You taste so good, kitten,” Derek rumbled, licking his shiny lips as blunt fingers slid between Stiles’ cheeks, pressing inward.
“Der—” Stiles choked, thighs trembling as two fingers pushed deep inside, all the way to the knuckle. It felt incredible. His insides clenched greedily around them, and he squirmed, pressing back desperately for more.
“Fuck,” Derek groaned, gaze locked on where his fingers disappeared. “Sucking me in so nicely, kitten.”
A third finger pressed in, and Stiles sobbed, the pleasure overwhelming. His cock was hard and aching against his stomach.
“Please—Alpha—please, I need—” His chest heaved, mouth open, dizzy from the overwhelming scent in the air. All he could smell—all he could think—was alpha. “—Something.”
“Shh. I know what you need,” Derek murmured, pulling off his shirt and dropping it carelessly onto the mattress.
Stiles’ eyes tracked the movement of fabric. He snatched it up with a small, kittenish growl and buried his nose into it with a moan.
Derek chuckled above him, then dipped back down. Stiles’ eyelids fluttered as Derek’s tongue licked into him alongside those long, thick fingers.
“Oh—” he gasped, biting into the dark fabric to muffle his moans as the heat in his belly peaked. His back arched, and his whole body trembled as he came.
The orgasm hit like a tidal wave, washing away any thoughts and leaving him boneless.
Derek shifted above him, murmuring heated words of praise, but Stiles’ brain had melted out of his ears, leaving him floating.
He vaguely registered his legs being lifted and adjusted, his pelvis turned, and a pillow tucked under his bottom.
Stiles purred, still clutching Derek’s shirt to his mouth, mouthing at the fabric, tasting the alpha’s scent through it.
He floated in the pleasant afterglow, basking in his alpha’s scent.
Then something hot and thick nudged at his rim, and Stiles moaned, automatically pressing back against it.
The head popped inside, and Stiles gasped—loud and sharp—while Derek groaned above him.
“Fuck,” Derek groaned, sounding almost pained as he rolled his hips in small, shallow thrusts. His glowing red gaze stayed fixed downward, watching himself sink into Stiles. “Look at you. So damn perfect.”
He leaned forward, bracketing Stiles’ smaller body beneath his larger frame.
“Gonna breed you, kitten,” Derek whispered, plucking his shirt from Stiles’ mouth despite the boy’s growl of protest.
“Gonna knot this little ass and pump you full of my seed,” Derek grunted, his hips pressing harder, until their bodies were flush.
Stiles sucked in small, stuttering breaths, chest heaving as Derek set a slow, steady rhythm.
"Uh,” he moaned as Derek’s hips gained momentum, the air thick with the wet slap of skin-on-skin. “Uh, uh, uh—”
Stiles reached up, clinging to the alpha with one hand while the other desperately clutched his prize to his chest.
“Look at you,” Derek groaned, licking into Stiles’ open mouth and making the omega whine for more. “Knew you’d look perfect on my cock.”
“Alpha,” Stiles slurred, arching up to chase Derek’s lips, drunk on the taste of him.
Derek grinned and gave him a chaste kiss before ducking his head to mouth at Stiles’ tender neck.
Stiles jerked, a choked noise escaping as Derek’s teeth and tongue worked over the freshly forming gland.
“Please,” he sobbed, body shaking as he arched his neck back as far as it would go. “Please, please, please,” he babbled, legs trembling where they hung loosely over Derek’s hips.
Derek growled, and Stiles’ insides clenched in response, feeling the heavy pressure of Derek’s knot beginning to form.
“Mine,” Derek growled, voice deep and animalistic, the word vibrating against Stiles’ skin.
“Yes—alpha,” Stiles whimpered, toes curling as Derek’s knot slipped in and out, nearly catching. “Yours.”
Derek snarled, then slammed his knot inside at the same moment his teeth pierced Stiles’ gland.
Stiles came with a scream, body arching taut—then everything went black.
He came to, wrapped in Derek’s arms—and judging by the alpha’s steady breathing, it had only been moments since he passed out.
He instinctively tried to shift, but Derek’s knot had them locked together. Stiles shuddered at the tug of it.
“Shh,” Derek murmured, tightening his hold. “Be still, kitten.”
“Am I pregnant now?” Stiles slurred, still warm and hazy, thoughts slow like crawling through mud.
Derek chuckled, pressing his nose to Stiles’ throat. “We won’t know that fast, kitten. It’ll take a couple of weeks—see if your scent changes.”
“Oh.” Stiles blinked up at the alpha. “Okay.”
“You’re going to give me such pretty puppies,” Derek whispered, smoothing a hand over Stiles’ stomach. “Aren’t you?”
“Yes, Alpha,” Stiles murmured, warmth blooming in his chest.
Derek shifted, lifting up to press heated kisses to Stiles’ lips, licking into the omega’s mouth until his breath hitched.
“When my knot goes down, I’ll help you build your first nest.”
“Nest?” Stiles blinked. He knew what it was, but his brain felt warm and hazy.
Derek tugged gently at the shirt still clutched in Stiles’ arms, and the omega immediately growled.
The alpha chuckled, clearly unbothered by Stiles’ possessiveness over the shirt.
“Yes, kitten. Looks like you’ve already picked the first piece.”
“Oh,” Stiles mumbled, blinking down at the fabric.
“At least it’s not my underwear,” Derek murmured, nuzzling his cheek.
Stiles’ nostrils flared, mouth watering at the imagined scent of Derek’s boxers.
“Where—” He squirmed, wanting it now, but Derek held him tight.
Derek let out a low huff of amusement as Stiles whined.
“You can pick whatever you want, kitten. After my knot goes down.”
Stiles pouted but relented, the promise easing the crawling urge inside him.
“After the nest,” Stiles whispered, staring up at Derek with wide, adoring eyes. “Can I have more chocolate? Please, Alpha?”
Derek’s eyes flashed red. “Anything you want.”
Stiles smiled, and Derek leaned down, kissing him breathless once more.
