Erik's knot pulsed hot and thick inside Alex's soaked pussy, locking them together as the alpha's breath ghosted over the bond mark. "Marry me, pup," Erik murmured, voice rough with need, one hand cradling the swell of Alex's pregnant belly while the other tugged the tail plug in lazy circles. "Be mine for good—no more rivalry, just this. Us." Alex's walls fluttered wildly around the knot, his clit throbbing under Erik's fingers, and the words shattered through him like lightning. "Yes—fuck, yes!" he wailed, cumming hard, slick gushing around the swollen base as his body seized and trembled, the bratty protests dissolving into ecstatic sobs.

They barely separated before Erik flipped him onto the bed and drove back in, cock slamming deep into that fluttering heat again and again. Round after relentless round blurred together—twelve in total—each one leaving Alex sobbing and clutching the sheets, tears streaking his flushed cheeks while he gasped "my fiancé" like a prayer, his belly bouncing with every thrust, nipples stiff and oversensitive as Erik's teeth claimed the bond mark anew. The tail plug stayed buried in his ass, shifting with every brutal snap of hips, the wet squelch of cum and slick filling the room as Alex's legs shook and his pussy clenched greedily, the intensity building until he was babbling through another shattering orgasm, calling Erik his fiancé with every broken cry.

By the final round, Alex was wrecked and glowing, body limp and sated beneath his alpha, the collar warm against his throat as Erik kissed the tears away, knot swelling one last time to seal their promise deep inside.

Erik's knot pulsed one final time inside the omega's drenched heat, but instead of softening, the alpha's grip tightened on Alex's hips, fingers digging into sweat-slicked skin as he rolled his omega onto his side. "Beg for it, pup," Erik growled against the bond mark, voice thick with command and affection, his free hand reaching back to twist the tail plug deeper into Alex's ass, the flared base rotating in slow, deliberate circles that made the omega's walls flutter and clench around the locked knot. "Beg Daddy for another knot—say it like you mean it, or I'll keep this plug stretching you until you're sobbing my name." Alex's breath hitched, his pregnant belly heaving as sparks of overstimulation shot through him, slick and cum leaking around the knot's base while his clit throbbed untouched; the bratty spark in his eyes flickered but gave way to raw need as he whimpered, "Please, Erik—fuck, knot me again, fill me up, I need it so bad."

The demand sent heat surging anew, Erik's cock twitching inside him as he worked the plug with firmer twists, the pressure against Alex's prostate drawing broken moans from the omega's throat. Their bodies moved together in that final, grinding rhythm, knot swelling fuller once more as Alex came with a shattered cry, his pussy milking every inch while tears of pleasure streaked his face. The intensity crested and broke, leaving them both trembling in the aftermath, limbs tangled and breaths ragged as the knot finally began to subside.

They collapsed together onto the rumpled sheets, Erik's arms wrapping protectively around Alex's swollen belly as the alpha nuzzled into his neck. "No more rivalry after this," Erik whispered, voice hoarse and tender, his fingers tracing lazy patterns over the curve where their child grew. "We finish the project, then it's us—raising this baby, building something real instead of fighting for top marks." Alex sighed, body lax and glowing with exhaustion, his hand finding Erik's and squeezing tight. "Yeah... just us, no more competing. Feels right, like it was always supposed to be this way."

Yeah... just us, no more competing. Feels right, like it was always supposed to be this way." Erik's hand stilled on the swell of Alex's belly, his breath catching as the omega's casual admission slipped out while they lay tangled in the sheets. "One-night stands, huh? And you took money for it too, pup? Letting strangers fuck this pretty pussy whenever they wanted?" The alpha's voice dropped low, laced with a jealous edge that sharpened into something possessive, his fingers tightening around Alex's hip as the revelation hit.

Alex giggled breathlessly, the sound bubbling up even as Erik rolled him onto his stomach and landed a firm slap across his ass, the sting blooming hot over skin still slick with their cum. "Erik—wait, it was just before, I didn't—ah!" The bratty laughter mixed with a whine as the alpha's hand came down again, then again, turning the omega's cheeks pink while his tail plug jostled inside him. "Please, mercy, Daddy, it didn't mean anything—giggle—I'm sorry, I won't... ahh, no more, it stings!" But the giggles dissolved into desperate pleas as Erik's palm kept falling, each smack jolting the knot's remnants and making Alex's clit throb against the mattress, his body arching back even as he begged for it to stop.

The punishment built until Alex's mind frayed, his giggles turning to incoherent babble, eyes glazing over as Erik's fingers plunged back into his aching pussy, scissoring deep and forcing more slick to gush around them. "Dumb little whore, aren't you? All mine now," Erik growled, thrusting harder, and Alex could only moan brokenly, "Dada... please... no think... just yours," his walls clenching helplessly while the alpha claimed every inch, pushing him deeper into that empty, blissful haze until nothing remained but the raw need to submit.

Erik's fingers withdrew with a wet sound, leaving Alex's pussy clenching around empty air for only a heartbeat before the alpha's cock replaced them in one deep thrust, burying to the hilt and stretching those fluttering walls wide once more. "Say it again, pup—whose are you?" Erik demanded, voice rough as he set a punishing pace, hips snapping forward hard enough to jolt the tail plug deeper into Alex's ass and make his pregnant belly rub against the sheets. "Tell Daddy you're his dumb little whore, say it like you mean it or I won't knot you again." Alex sobbed out the words between broken moans, "Yours, Erik—fuck, all yours, Dada owns this pussy," his body rocking back to meet every thrust as the confession spilled freely, clit grinding against the mattress with each brutal drive.

The rhythm turned relentless, Erik's hand fisting the collar to arch Alex's back while he growled for more, "Louder, brat—confess who owns every inch," until the omega was chanting it mindlessly, "Only yours, please knot me, I'm yours," slick gushing around the pistoning cock. Between gasps, Alex confessed in a rush, "I rigged the math project to pair us—I wanted to fuck with you, make you lose control," his walls squeezing tight as Erik's grin flashed against his neck. "Knew it all along, pup," the alpha murmured, nipping the bond mark while driving in deeper, "just wanted to hear you admit it before I knocked you up and made you mine for real." The words sent Alex spiraling into another shattering orgasm, his body milking Erik's swelling knot as the alpha filled him again, sealing the admission deep inside with possessive heat.

Erik's knot throbbed deep inside Alex's clenching heat, the thick pulse of cum painting his inner walls as the omega's body quivered through the aftershocks. Alex's pregnant belly pressed against the sheets, slick and sweat cooling on his skin while the tail plug shifted with every tiny twitch of his hips. The confession spilled out in a breathless rush between gasps, "It was fake—the test, Erik, I faked it to trap you into this pairing, to make you claim me for the project and everything after." His voice cracked with a mix of guilt and defiant thrill, walls fluttering around the locked knot as if the admission itself sent fresh sparks through his oversensitive nerves.

Erik went still for a heartbeat, then growled low against the bond mark, his hand cracking down hard across Alex's ass in a sharp slap that jolted the plug deeper into his hole. "Faking it to snare your alpha, you conniving little brat?" Another smack landed, then another, the sting blooming hot and red across the omega's cheeks while cum and slick leaked around the knot's base. Alex moaned into it, pushing back into each punishing blow with masochistic eagerness, his clit grinding against the mattress as tears of pained pleasure welled in his eyes. "Yes, Daddy—harder, punish me, I deserve it," he babbled, body arching and trembling under the relentless spanks that left his skin flaming and his pussy squeezing greedily, the pain twisting into raw, addictive heat that made his cocklet leak and his mind haze over in blissful submission.

The alpha's fingers dug into the heated flesh, twisting the tail plug with cruel precision while his free hand delivered another volley of slaps, each one drawing broken sobs and needy whimpers from Alex's throat. "Take it like the desperate whore you are," Erik snarled, hips grinding the knot deeper as Alex's walls milked him through the punishment, the omega's ass reddening beautifully under the assault. Alex sobbed out his surrender, "Yours to punish, only yours," his body rocking back for more even as the sting layered over the fullness in his pussy and ass, every slap sending jolts straight to his throbbing clit until he was coming undone again, slick gushing fresh around the knot in ecstatic waves of masochistic release.

Alex's body still quivered around the fading knot, slick and cum trickling down his thighs as the alpha's hand finally eased off his reddened ass. Panting into the sheets, the omega's fingers drifted down between his spread legs, brushing tentatively over his swollen clit in slow, lazy circles that barely chased the lingering sparks of release. Erik watched for a moment, breath hot against the bond mark, before a low growl rumbled in his chest at the deliberate pace. "Too fucking slow, pup," he muttered, annoyance sharpening into command as he batted Alex's hand away and sank two thick fingers straight into the dripping pussy, curling them hard against the sensitive walls while his thumb rubbed firm, teasing strokes over the oversensitive clit. Alex jolted with a broken cry, overstimulation crashing through him in waves that made his pregnant belly tighten and his legs shake, every deliberate thrust of those fingers pushing him higher even as Erik's other hand pinched and rolled the tender nub until the omega was sobbing from the raw, too-much pleasure.

The alpha worked him relentlessly, scissoring deep and flicking that throbbing clit with quick, precise touches that had Alex thrashing and babbling, tears streaking his face as another forced orgasm ripped through him, slick gushing around the invading digits. Just as the climax peaked, Erik pulled back abruptly, leaving Alex clenching empty and desperate, then reached for his phone on the nightstand. "Look at the camera, brat," Erik ordered, voice rough with possession as he angled the lens at Alex's flushed, wrecked form, the tail plug still twitching in his ass and his pussy visibly pulsing. "Tell them whose dumb little whore you are now. Say how you rigged everything just to get this knot and this baby—loud and clear, or I won't touch you again."

Alex whimpered at the sudden withdrawal, hips bucking futilely toward nothing as overstimulation left his clit aching and his mind hazy, but the threat of denial had him scrambling to obey with frantic desperation. "I'm Erik's dumb little whore," he gasped into the camera, voice cracking as fresh tears welled, "I faked the project to trap him, to make him claim my pussy and knock me up—please, Daddy, I need your fingers again, need you to own me on film, I'll say anything, just touch my clit, make me cum while you watch..." The words tumbled out in a rush, each lewd confession fueling the heat in Erik's eyes as he kept the phone steady, capturing every trembling admission.

The phone screen flashed an incoming call from their project advisor, the name lighting up across the still-recording lens just as Alex's final words trailed into a shaky breath. Erik's grin sharpened with mischief, his knot still pulsing thick inside the omega's fluttering pussy as he thumbed the answer button and brought the device to his ear without missing a beat. "Professor Hale, perfect timing," he said smoothly, voice steady even as his free hand slid down to grip Alex's hip, holding him pinned to the sheets. Alex's eyes widened in panic, a soft whine escaping before Erik's fingers pressed firmly over his lips, the alpha's hips rolling in a slow, deliberate grind that dragged the knot deeper and forced a muffled whimper against his palm.

"Everything's on track for the deadline," Erik continued into the call, his tone laced with that cocky edge while his thrusts picked up a careful rhythm, the wet slide of his cock through slick and cum echoing faintly in the room. Alex trembled beneath him, pregnant belly pressing into the mattress as overstimulation coiled tighter with every inch, his clit throbbing untouched and his walls clenching greedily around the intrusion. The advisor's voice droned on about equations and submission files, oblivious, but Erik's teasing grew bolder—he angled his hips to drag across that sensitive spot inside, whispering low against Alex's ear between responses, "Quiet now, pup, or he'll hear how desperate you sound." Alex bit down on a moan, body arching as the pace intensified, the risk of discovery sending fresh heat surging through him until his thighs shook and his pussy spasmed around the thick length.

Erik's restraint snapped at the first near-slip, the alpha hanging up mid-sentence with a curt excuse before flipping Alex onto his back and driving in hard, one hand clamping over the omega's mouth to stifle the cry that tore free. "Behave," he growled, hips snapping forward in relentless, pounding thrusts that jolted the tail plug deeper into Alex's ass and made his swollen belly bounce with every impact. Alex's muffled moans turned to quiet, desperate whimpers against Erik's palm, his walls fluttering and clenching as the rough fucking pushed him straight into another shattering orgasm, slick gushing around the knot's base while tears streaked his flushed cheeks. The intensity built in waves, Erik's cock claiming him deeper with each brutal drive until the omega surrendered completely, body lax and glowing in submission as their shared heat sealed the moment tighter than any rivalry could break.

Erik's knot throbbed one last time before easing, leaving Alex slick and trembling as the alpha eased out with a wet pull. They shifted naturally into a tangled cuddle on the rumpled sheets, Alex's body now lean and unburdened, his skin cooling against Erik's chest while the tail plug rested forgotten on the floor. The omega sighed into the embrace, fingers tracing idle patterns over Erik's forearm, the rivalry long dissolved into this raw, possessive closeness.

" Erik," Alex murmured, voice hoarse from earlier cries, "I can't handle these heat cycles anymore. They wreck my focus in class—every lecture blurs into this constant ache, and I need you to kill them off for good. Breed me deep and permanent, make it so I don't spike like this again." The plea hung between them, laced with that familiar bratty edge softening into need, and Erik's eyes darkened instantly, a low growl rumbling as he rolled Alex beneath him without hesitation.

In a heartbeat the alpha pounced, pinning wrists above his head and slamming back inside that fluttering heat with one brutal thrust, cock stretching Alex wide as he set a punishing rhythm. "That's it, pup—beg for it," Erik snarled, hips snapping hard enough to jolt the bedframe while his knot began swelling again, locking them tight. Alex moaned brokenly, walls clenching greedily around the thick length as Erik drove deeper, each thrust grinding against his prostate and sending sparks through oversensitive nerves. Cum and fresh slick gushed with every withdrawal, the wet slap echoing as Erik claimed him relentlessly, one hand gripping his hip to angle deeper, the other sliding between them to rub firm circles over his swollen clit until Alex sobbed his submission, body arching and milking the knot that pulsed hot inside him. The breeding took hold in waves, Erik filling him over and over with possessive heat, sealing the promise to end the cycles while Alex clung to him, lost in the overwhelming pleasure and the bond that bound them tighter than ever.

Erik's knot finally slipped free with a wet gush of cum and slick, but the alpha didn't give Alex a moment to catch his breath before hauling him up by the collar and marching him straight to the kitchen counter. "Not done with you yet, pup," Erik growled, bending the omega over the cool marble so his pregnant belly pressed flat against it, then slamming back inside that dripping pussy in one savage thrust. Alex cried out, legs buckling as the thick cock speared deep, the wet slap of skin echoing off the cabinets while Erik's hips pistoned relentlessly, one hand pinning Alex's wrists behind his back and the other reaching around to pinch and tug his swollen clit. "Gonna fuck you in every room till you can't even think about leaving my bed tomorrow—stay here, stay mine, let Daddy wreck this greedy cunt so bad you limp through class." Alex moaned brokenly, pushing back into every brutal drive, his walls fluttering and clenching as fresh slick poured down his thighs, the tail plug forgotten on the floor but the memory of it making his ass twitch with every punishing snap of hips.

They barely made it to the bathroom before Erik dragged him inside, shoving Alex against the shower tiles and hoisting one leg up to split him open wider, cock driving in at a punishing angle that ground straight against his prostate. Water cascaded over them as Erik fucked him hard and deep, the omega's belly rubbing the slick wall while he sobbed and begged, "Harder, Daddy—fuck, don't stop, breed me again, I can't walk after this, please knot me till I'm ruined." Erik's teeth sank into the bond mark as he obliged, knot swelling thick to lock them in place, cum pulsing hot and endless into Alex's spasming pussy while his fingers worked the omega's clit in tight, relentless circles until Alex came with a shattered scream, body shaking and gushing around the knot. From there it was the bedroom again, then the living room couch, Erik bending him over every surface, claiming him in every position—on his back with legs hooked over Erik's shoulders, riding the alpha's cock with his belly bouncing, even on all fours with Erik's hand fisted in his hair—each round leaving Alex more wrecked, thighs trembling, voice hoarse from crying out "yours, only yours" as the promise of staying over solidified with every load pumped deep inside him.

After the marathon of claiming across every surface, Alex pulled away with a huff, still annoyed over Erik's smug sabotage during their shared lecture that afternoon—stealing his notes and winking at the professor like it was all a joke. He flopped onto the couch, controller in hand, booting up his game to zone out and ignore the alpha entirely, muttering under his breath about how Erik could "fuck off until he learned to act right." Erik watched for a beat, cock twitching back to life at the bratty dismissal, then crawled over to straddle the edge of the cushions. He cupped Alex's jaw and dove in for a deep, tongue-twining makeout, sucking on his lower lip while grinding their hips together, the apology spilling hot between kisses: "Sorry, pup, I was an ass at school—won't do it again, just wanted your eyes on me." Alex's resistance cracked with a moan, controller dropping as he forgave with a nip to Erik's tongue, climbing into his lap to sink down on that thick cock in one slick glide, walls stretching wide around the girth as he rode with rolling hips, belly pressing into Erik's chest while the alpha thrust up hard to meet every bounce.

Erik's excitement snapped his control, hands gripping Alex's ass to flip them into a frenzy of positions—first missionary on the floor with legs pinned back for brutal, cervix-kissing depth, cock pistoning through clenching heat as Alex screamed "yours" with every wet slap; then doggy over the coffee table, tail plug shoved back in to double the stretch while Erik railed his prostate in punishing rhythm, fingers circling that swollen clit until slick gushed down trembling thighs; even standing against the wall next, one leg hooked high as the alpha hammered in from below, knot swelling to lock them grinding through another gushing orgasm. Alex babbled brokenly through it all, body jolting and milking every thrust, the raw intensity building with filthy praise and the sound of skin meeting skin until Erik had worked him through every angle, filling him relentlessly until both were spent and panting in a heap.
