Mack could smell him. The bitter yet alluring mix of salt and whiskey that made up Will’s scent was seeping out from underneath Will’s bedroom door in a way that made Mack’s eyes water and his cock twitch.
Will was going into rut. Clearly.
Mack wasn’t sure what to do. He was only a beta, for fucks sake. He couldn’t exactly support an alpha through his rut. Thoughts and feelings surged thick and hot in his gut, all melding together until they sounded like one word on repeat. Placeholder, placeholder, placeholder.
With a whimper, Mack bit onto his lower lip. He wasn’t sure what to do. He’d never been in this situation before. Not with an alpha, at least. Connor’s heats tended to be irregular, and Mack had helped him with them in the past, but Connor was an omega. Mack just had to fuck him through that, knot or no knot. It pleased the omega all the same. Took longer, sure, but it still worked.
Alphas, on the other hand, always wanted to fuck, and Mack wasn’t sure his body would be good enough. It wasn’t built to take a knot, after all, not the way omegas’ bodies were. Mack sighed and looked down at the ground, eyes catching on his shirt instead.
It was Will’s, the one he’d worn to Will’s hockey game. Him and Connor had shouted their throats raw cheering for the Eagles, and they’d been rewarded for it. Well, maybe that wasn’t entirely true. Connor had inherited a slew of alphas that wanted him. He didn’t feel the same.
And whilst Mack had sort of gotten a reward, he’d actually been the one to give it. After the game, Mack had waited for Will, ready to restart their courtship. Will had almost cried before he’d changed tactics, instead lifting all of Mack’s chubby form into his arms and pressing him against the wall, their lips melding together.
And now Mack was freaking out, toes inches away from Will’s bedroom door, and he couldn’t do anything to stop it. He was about to turn back and run off when the door opened before him. Will stood on the other side, skin flushed and clammy with sweat.
“Why… what are you doing out here? You can come in, you know?” Will said. He sounded sick with want and Mack gulped, the sound too loud in the dim quiet of Will’s hallway. Will sniffed at the air, and Mack was suddenly reminded that his scent was spiking, blueberry jam overwhelming his senses.
“Um… I came to see if you want to hang out, but, but, you, um, you’re in rut,” Mack spluttered out. He felt useless, tongue thick and swollen in his mouth. His cock was starting to hurt now, straining in his pants as Will’s thick scent swam around him.
“Not just yet. It’ll start tonight,” Will said. He was slowly shuffling forward, hands lifting up to grab Mack’s waist. His fingers sunk into Mack’s plush thickness and Mack couldn’t help but squirm. “Come ‘ere. You smell… fuck, you smell amazing,” Will cursed. He pulled Mack inside his room, the door slamming shut behind them, before he was burying his face in Mack’s neck, sniffing and biting in an uncoordinated pattern.
“Will, stop, Will. I c-can’t, um, I can’t help you,” Mack hiccupped. The pleasure was too good, leaving him dizzy and unsteady on his feet. He didn’t pull away. He couldn’t. He knew he had to stop them though. It would only hurt them both if they continued. Will growled lowly in his throat and pressed them further against the door, teeth biting down onto Mack’s shoulder.
“You don’t want to help me?” Will asked. Mack whimpered. That wasn’t what he’d said at all, but he knew it was Will’s inner alpha taking over, rejection making him grouchy and grumpy. Mack panted softly and adjusted in place.
“I… I do want to help but Will… you keep forgetting I’m a beta. My body isn’t designed for your knot,” Mack said. Will growled again and bit Mack’s neck. Mack gasped, hands flying up to sink into Will’s sweat-knotted curls. It was so close, so close, to his mating gland. “Do… do you want me to find someone, ah, someone to help?”
“You. Want you,” Will huffed. He looped his hands under Mack’s thighs and lifted him up, entirely uncaring when Mack squeaked and asked to be put down. Will pressed kisses along his jaw as he carried Mack through towards the bed, ignoring Mack’s mutters about being too heavy. “No. My beta.”
“B-but I’m heavy,” Mack squirmed. Will squeezed Mack’s thighs harder, the flesh of his palms almost searingly hot. He dropped Mack against the bed and pulled back the tiniest amount, lips latching onto Mack’s neck once more.
“Betas can take knots, baby. I promise,” Will muttered. Mack gasped softly, failing to register Will’s words as his back arched up into Will’s touch. He felt the alpha’s hands slip under Mack’s (Will’s) shirt, fingers deftly toying with one of Mack’s nipples. “Gonna look so pretty stuffed with my knot, baby.”
“P-please, alpha,” Mack begged. He felt heady and dizzy already, desperate for Will to take him. Even if he couldn’t take Will’s knot, he’d try his hardest. For his alpha, he’d try anything.
“Mm. Such a good beta for me. Wearing my clothes, telling everyone who you belong to,” Will grumbled. He pulled back from marking up Mack’s neck and stared down at him, eyes half-lidded and hazy with lust. “Fuck, I’m not even properly in my rut yet, and you’re already driving me insane.”
“’M sorry,” Mack slurred. He wasn’t sure why he’d said it, but he did. Will shushed him, hands slipping out from under Mack’s shirt to instead tug at his jeans. He popped open the button and undid the zip before all but tearing them down Mack’s legs. Mack shivered, legs bowing together. His thighs squished against one another, and he whimpered.
Will growled, wedging his hands between Mack’s thighs and forcing them apart. “Don’t hide from me, baby. Let me see all of you,” Will practically purred. Mack whined but didn’t try to fight his alpha. He kept his legs open, even when Will peeled off his boxers, exposing his cock.
Mack wasn’t stupid. He knew he was smaller than an alpha – all male betas tended to be – but he couldn’t help but feel embarrassed. Would Will be ashamed of him? Deem him an unworthy mate? He was whining before he could stop himself. “Sorry.”
“Stop saying that,” Will huffed. He sunk to his knees and wrapped one hand around Mack’s cock, almost engulfing it in the process, before he lapped at the tip, moaning softly. “You taste as pretty as you smell.”
Mack moaned in response, hips canting up before he could stop himself. Will didn’t react, just opened his mouth wider, hand falling away as he took more of Mack’s length into his mouth. Panting softly, Mack stared down at his alpha. His alpha that was on his knees for Mack, laving his tongue over Mack’s small cock like it was the best thing in the world.
“Fuck, Will, please,” Mack begged. He wasn’t sure why Will was so intently lavishing attention on his cock. It wasn’t like Mack was the one going into rut. He’d half expected Will to have jumped his bones by now, desperate to get his dick wet.
Then again, Will had said that he wasn’t entirely in rut yet. Maybe this was just how alphas were at this stage of their cycle. Devoted and loving, absolutely ready and willing to worship their omega.
Omega. Fuck. Mack wasn’t one of those, and yet somehow, Will’s tongue had made him forget about that. Mack whimpered again and tugged at Will’s curls, pulling him up and off his cock. Will went, eyebrows pinched together as he stared up at Mack’s teary face. Mack sat up and shuffled backwards, body tucking against itself as he tried to cover his crotch. He didn’t want his alpha to see him.
Will’s shirt still hugged his chubby frame, and he fiddled with the hem as tears started dripping slowly down his cheeks. “Baby? What’s wrong?” Will asked, voice almost cautious as he spoke. He clambered onto the bed, gently soothing a hand through Mack’s unruly strands. “Talk to me, Mackie, c’mon.”
“Will. I’m not an omega. I can’t help you,” Mack sobbed. His body was shaking. He felt insane, both strung up and stretched taut, yet loose and floaty. The feeling of Will’s mouth on his cock had left him muddled and confused. He barely knew what to do about it, let alone what to do about himself.
“Baby… I’ve already told you betas can take knots, why don’t you trust me?” Will said. Mack looked up at him, blinking the tears from his eyes. He’d never heard that in his life, and it must’ve shown on his face because Will frowned and lifted a hand up, soothing his thumb along Mack’s damp cheek. “It’s true, I promise.”
“A-are you sure?” Mack asked. He sniffled unattractively, entirely unaware of how grotesque he must seem. “Don’t just sweet talk me to make me feel better. Tell me the truth.”
“I am,” Will said. He slowly pushed Mack against the sheets, settling between his spread legs. Mack sniffed as he looked up at him, Will’s salty whiskey scent washing over him in soothing waves. Mack found himself relaxing almost immediately. “Do you trust me, baby?” Will asked. His eyes were searching and Mack found he couldn’t look away. Didn’t want to, either.
“Yes. Yes, I trust you.”
~~
Mack wasn’t sure what time it was, only that it was nighttime. The curtains were half drawn, and the full moon peeked through, shimmering in Mack’s gaze. Mack sighed. He could feel the heat radiating in waves off of Will’s skin and he wanted to wake him up, to help him feel better, but he also knew that once he did, it was game over.
Will would learn very quickly that his assumption of betas being able to take knots was false. He would realise the error of his ways, and everything him and Mack had been working towards would crumble like a cookie held in a glass of milk for too long.
Mack sighed and slipped from the sheets, padding across to the windowsill. He was still wearing Will’s jersey, the alpha growling and nipping at his fingers every time Mack had tried to remove it. The white of it practically glowed in the moonlight. He leant his stomach against the wall and rested his head on his hands, elbows perched atop the windowsill.
As the moonlight shone down on him, Mack allowed himself to think. Will was… Will was one of a kind. He was an alpha who didn’t mind that his partner was physically bigger than him. He was an alpha who didn’t care what subgender his partner was, as long as they loved him. He was an alpha with too much love in his heart.
He was an alpha that was right behind Mack, his scent sharp and bitter, and Mack knew he was definitely in rut now. Could feel the sharp pang of warmth against his back, Will’s weight resting against him. His skin was boiling hot. “Will.”
“Come back to bed,” Will muttered. Mack shivered at the roughened nature of his voice. Will sounded delectable, desirable, delicious. Mack wanted to give in, but he merely hummed and shook his head, leaning back in Will’s embrace. “I will take you right here, beta, don’t tempt me.”
The way he snarled sent a shiver through Mack and he couldn’t help but preen, pressing his ass back against Will’s length. It was thick and hard, and Mack’s mouth watered with want. “Do it,” he whispered. He vaguely remembered his concerns, his fears, but his cock was in control now.
And Mack was desperate to be filled.
Will growled, the sound making Mack’s eyes roll back. He felt Will’s fingers nudging at his hole and he gasped when he realised he could feel faint traces of wetness. “Did… did you get lube or something?” Mack whimpered.
“No baby. That’s just you,” Will purred. He sounded cocky. Mack whined, head tipping back against Will’s shoulder, even as confusion forged its way through Mack’s veins. He stuttered out a shaky ‘how’, breath catching in his throat when Will’s digits pressed against his rim. “The ideas that only omegas produce slick is wrong. Betas produce slick too, just not as much as omegas.”
“R-really?” Mack stuttered. Will nodded and pushed a finger into Mack’s tight heat. Mack moaned softly and fell forward, head resting against the cool windowsill. If he focused hard enough, he could feel the slick lining his hole and he tried to push it out, desperate to coat Will’s fingers with it.
Will groaned in delight and slipped a second finger in alongside his first. “Wanna know something else baby?” Will asked. Mack hummed, shifting his hips back against Will’s hand. He felt sick with need. Was this how omegas felt during their heat? “Some betas can even produce as much slick as a weak omega, especially once they’re mated.”
“Fuck, Will!” Mack cried out. The words had barely affected him, but the searing pressure of Will’s fingers against his prostate most definitely had. He reached back and curled his fingers around Will’s wrist, freezing his motions in place. Will shushed him softly, soothing his other hand over the ridges of Mack’s spine.
“Shush, I’ve got you baby. I’m gonna knot you so well. Pup you up,” Will hissed. His words were slurred, voice dripping with lust. Mack whined and released Will’s wrist, allowing him to start his motions up once more. He pushed a third finger inside Mack’s heat and spread them for a few moments before he finally pulled back.
“Please, alpha, knot me,” Mack begged as he looked over his shoulder at Will, batting his lashes as coyly as he could. The alpha groaned, head tipping back, before the tip of his cock was nudging against Mack’s entrance. Mack whined and shifted his hips back, gasping when he felt the tip slip into his hole.
“Baby, fuck. You’re so fucking tight, oh my god,” Will groaned out. He sunk all the way to the base, hands finding their way to the dips of Mack’s waist. Mack whimpered, clenching around Will without meaning to. Will hissed. “Can’t wait to fuck you full of my cum, baby.”
“W-want it, alpha,” Mack cried out. He looked out the window, all too aware of the people around them, too far to hear, yet almost too close enough to see. “Will, come on. Kn-knot me already.”
“I’ve got you, beta, don’t you worry.”
~~
Will was truly out of it now. Mack could see it in the milky sheen of his eyes. Slowly lifting up and sinking back down again, Mack whined. Will’s cock was so deep in his hole, and he was leaking slick everywhere. His thighs were damp with it, and each time he sank down, it made a wet noise, causing Will to groan.
“F-faster, beta, c’mon Mack,” Will hissed out. That was all he could really say. Faster, harder, beta, Mack. Those four words and very little else. Macklin didn’t want to go faster. He knew he was heavy, and he didn’t want to hurt Will whilst riding him. He’d never forgive himself if he did.
“B-but…” Mack started. Will growled, fingers digging into Mack’s bruise-mottled flesh as he coaxed Mack into moving faster. Mack whimpered, fingers digging into the defined nature of Will’s pecs. His alpha was still growling underneath him, hips jackrabbiting up into Mack’s hole.
“Good beta, my beta,” Will hissed. Mack knew that meant Will was about to cum, and sure enough, his alpha filled him up again, knot slipping past Mack’s rim as he tugged him down for a kiss. Will’s fingers curled around Mack’s cock, and Mack whimpered, hips stuttering forward.
“’M gonna cum, alpha,” Mack whined. He pulled away from Will’s hold, his head tipping back as Will continued to stroke his cock. It took only a few more strokes and a rumbled exclamation of Mack’s name from between Will’s lips before Mack was cumming again. “Alpha!” He wailed.
Will rolled them over once Mack had calmed down and buried his face between Mack’s chest, mouth suckling on the fattened flesh. He’d been doing it occasionally and it made Mack’s head hurt. “Fuckin’ love your tits,” Will slurred before he went back to biting and sucking. Mack whimpered.
“A-alpha, don’t be stupid. Betas don’t,” Mack swallowed down his tears, “betas don’t have tits.” He’d seen plenty of omegas refer to their chest as tits, but it wasn’t something he’d ever heard a beta do. He’d never seen anyone refer to a beta’s chest as tits either, not like they did omegas. He wasn’t sure why Will was doing it now.
“Mm… my beta does,” Will said. He was drooling, spit trickling from his mouth as he laved his tongue over Mack’s chest. His chin was shiny with it. Spit was drying patchily, all sticky and tacky on Mack’s skin, but he could barely pay that any mind.
Will was referring to Mack’s chest as tits because of his weight, and that made Mack feel something. Something heady and delicious. Rather than insecure, Mack felt loved. He huffed softly before pulling Will’s body firmly between his legs. Will lifted his head from Mack’s chest, mouth still dripping with spit. Mack’s cock twitched at the sight.
“Baby?” Will slurred. Mack bit his lower lip before he pressed his chest together, emphasising the bulk of his flesh. Will’s rut-hazed eyes immediately shot down, staring at the thickness of Mack’s skin. His irises were entirely swallowed up, only the wide-blown haze of his pupils still visible. “Fuck.”
“Does alpha like my t-tits?” Mack stuttered. It made him cringe, but Will groaned almost immediately, hips twitching into Mack’s hole as he lowered his face down again, sucking at Mack’s nipples. Mack whined and buried his fingers in Will’s hair, coaxing and guiding. Will moaned, the sound rippling through Mack’s system.
Fuck, he loved his alpha.
~~
Soft kisses dotted his skin and Macklin grumbled as he slowly blinked awake. He could smell whiskey and he smiled, hands blindly sinking into Will’s hair. “Alpha.”
“Morning, baby,” Will greeted. He stopped kissing his way over Mack’s stomach and let Mack’s shirt fall back into place, before he slowly captured Mack’s lips. Mack hummed and tightened his arms around Will’s neck, tugging him in further. His legs spread too easily, allowing Will to settle comfortably between them.
“Is it over?” Mack asked. He’d been fucked so many times during the previous day that he’d lost count of how many times it had happened. All he knew was that his alpha needed him, his body could take his alpha’s knot, and Will’s shirt, which still covered his body, was absolutely filthy.
“It’s over,” Will said. He pulled back, and Mack finally opened his eyes. Sunlight haloed Will from behind, accenting his tangled curls in a mist of light. He looked almost angelic from this angle, and Mack scanned Will over and over, trying to capture each and every detail so he could remember it when the two parted.
“Did I help?” Mack asked. He couldn’t help it, not when his insecurities were burning up in his gut. Will chuckled fondly and leant down once more, capturing Mack’s lips again. It was coaxing and smooth and soft – everything Mack wanted (nay, needed) and more. Mack sighed softly. When Will pulled back, his thumbs soothed over Mack’s hips, lightly pressing against the bruises that now dotted his skin.
“That was the best rut I’ve ever had.”
~~
When Mack looked in the mirror later that day, he wasn’t entirely surprised by what he saw. Fingerprint bruises lined the meat of his hips and thighs, and purpling love bites dotted his chest. He showed them to Will, not entirely surprised when his alpha laughed in response.
“Can you blame me? I love my baby’s body,” Will purred. His arms circled Mack from behind, hands kneading and squishing at the soft flesh of Mack’s pudgy tummy. It was a bad habit he’d picked up, something that Mack could never get at Will for. He’d tried. With a fond hum, Mack leant back into Will’s hold. “Don’t you love it?”
“Mm… as long as my alpha loves it, that’s all that matters.”
