Ari didn't know how long he'd been drifting--lulled into a fragile calm by the slow thrum of his alpha's heartbeat against his back and the dull ache of being stretched open around his knot. Rune had gone still, save for the soothing motion of his hand stroking over Ari's stomach, his chest, the soft murmurs against his skin. It felt safe.
But then it started again.
It always started subtly. A flicker under his skin. A low burn in the pit of his stomach. His body never gave him time to fully recover--not in the middle of his first heat--and even though he was boneless and fucked-out, he was already beginning to tighten again. Need surging back like a tide.
Ari whimpered quietly, rubbing his thighs together before Rune's hand settled on his leg, halting the motion.
"...it's starting again, isn't it, baby?"
Ari nodded. His voice was just a breath. "
Hurts...
"
Rune kissed his shoulder, groaning softly as Ari clenched around his knot involuntarily, the tension and heat in his little omega sparking against every nerve ending. "I know. I've got you. Just let it happen, sweetheart."
His knot was still seated deep, pulsing faintly with the aftershocks of their last round--but Ari was growing slicker again, and the heat made him restless. He rocked against Rune's hips, needy, overwhelmed by how fast the need was returning. Tears welled up again, unbidden, hot and frustrated.
"I c-can't--" Ari whined, "I don't know what I need anymore, I--Rune, alpha,
please
--"
Rune's voice dropped into a low, calming timbre. "You need me. That's all you need to know."
He shifted them again, pressing Ari flat to the bed, keeping them joined as he hovered above. His large hand flattened between Ari's shoulder blades, grounding him, pushing a fresh whimper from his lips as the knot tugged deep inside. "Breathe for me, baby."
"I'm trying," Ari gasped, voice thin and trembling. "I just-- it's too much, it's too hot--"
"I know, I know..." Rune's voice was still calm, patient even through the thick haze of his own arousal. His body was responding to Ari's scent, his writhing, the sheer need that radiated off of him like heat lightning. "Let me help, baby. Let me take care of it for you."
Ari sobbed when Rune started to move again. It was slower this time--gentler. He eased his knot free with a wet pop that made Ari cry out and clench, the emptiness devastating, until Rune filled him again with the next thrust. Deep, unhurried.
He was so open, so ready, slick pouring down his thighs. Every time Rune bottomed out, he let out a choked moan like he couldn't believe the ache was finally being soothed again.
"That's it..." Rune kissed his spine. "So perfect like this. Open and dripping, just for me."
His fingers found Ari's again, threading through them and squeezing tight. "I can feel you, baby. Every flutter. Your body wants this. Don't fight it."
Ari arched under him, helpless, another whimper torn from his throat. "
Alpha, please--
"
"I know, sweetheart. I know." Rune whispered, picking up the pace just a little, just enough to make Ari's breathing stutter, to set the fire burning bright again in his core. "Gonna knot you again, fill you till it takes. That what you want?"
"Yes--yes, please, need it--need it so bad--" his voice broke again into a sob as the pleasure surged through him, messy and wild.
Rune was breathing hard now, the control he'd been clinging to starting to unravel under the weight of Ari's heat and his own instincts. The bed creaked as his rhythm deepened, hard enough to rock Ari forward on the mattress.
"You're so greedy when you're like this, baby," Rune growled, voice fraying at the edges, "so desperate for my knot--fuck, you're milking me already."
Ari's body was clutching him, drawing him in with every thrust, begging without words. His scent filled the room--thick, slick-sweet, and painfully needy.
Rune let out a deep, primal growl and slammed into him one final time before his knot began to swell again, catching hard at Ari's rim.
Ari moaned--loud and unashamed--as his orgasm detonated again, soaking the sheets beneath him, body seizing around his alpha as Rune locked them together, knot pushing deep, forcing every drop of cum to spill into him all over again.
It was too much, so much, and it was perfect.
Rune slumped over him, one arm curling around Ari's waist protectively, the other cradling the back of his head as he whispered soothing nonsense into his hair. "Good boy, such a good boy, baby. So fucking pretty when you cum around me."
Ari was trembling, tears sliding freely down his cheeks as he blinked in the aftermath--wrecked, stuffed full, and still glowing with heat.
And even as they lay there--knotted again, locked together in the slick-sticky mess of Ari's nest--Rune could feel his omega's body already beginning to tremble with the next wave.
The next stage was already coming.
Rune could feel it--beneath the aftermath glow, the trembling in Ari's thighs, the way his fingers curled too tightly into the sheets again. Even knotted, even full of cum, even held down and kissed and praised--his omega's body wasn't done.
Not even close.
"
Fuck,
" Rune breathed softly, brushing sweat-damp hair from Ari's face, "You're still burning up, baby..."
Ari whined in response, low and aching, his head pressed to the bed, hips twitching helplessly despite the knot locked deep inside him. He was delirious--feverish with need, his body overriding everything else. Even his exhaustion. Even the ache. Even the overstimulation that should've made him still.
"I-it's too much," Ari whispered, but his hips were already trying to roll back again. "Can't--can't stop it--can't--" a sob escaped him, one he tried to muffle in the blanket, "Alpha--please--
Rune's heart twisted, but his cock throbbed where it was buried deep. His body responded instinctively to that whine, to the slick sound of Ari's body clenching so helplessly around him. He pressed a kiss to the nape of his neck, breathing deeply against the soft curve of his shoulder.
"I've got you," Rune murmured, voice a velvet rasp, firm and warm as a command, "I've got you, sweetheart."
Ari let out another sob, shivering under him. His entire body ached. His thighs were shaking again, ruined and sore, but still needing. Still chasing. Still begging. "Hurts," he whimpered, but even then, his hole fluttered around Rune's knot, milking it greedily.
"I know it does," Rune whispered, threading their fingers together, "It's your body, baby. It's doing exactly what it was made to do. And I'm right here. I'll give you everything it's crying for." He shifted his hips slowly, just a bit, letting the knot drag at Ari's rim and making the omega keen, toes curling at the burn of it.
"There it is," Rune purred, voice darkening. "That's what you need, huh? Need me to fuck you even while I'm knotted?"
