Work Text:
Dan Heng was on his way home from work like most week nights when he caught the faintest smell in the air. It nearly had him stopping in his tracks, the scent deeply alluring. It was masculine, a deep cedar scent with something akin to ash or hot metal mixed in, but was also pure. Glancing around, no else had seemed to pick up on it which wasn't surprising given how faint it was. As a dominant omega he could pick up on pheromones far more easily, but was also less susceptible to their effects. He focused in on the scent, making it as subtle as possible as he followed it down the street. The omega had a feeling he knew what he was going to find, and his heart fluttered at the sight of a young boy sitting on a bench, his face flushed and full of concern.
The boy couldn't have been older than 15 from first glance, and Dan Heng knew he had been correct in his assumption for the purr aspect of the scent. This was an Alpha going into rut for the very first time. The scene before him was tantalizing, but he was also worried for the boy. If it was anything like his first heat going though it alone was very, very unpleasant. With that thought in mind he stepped up to the boy, crouching down in front of him.
“Hey, are you okay?” He asked softly, releasing a small amount of pheromones to help calm the boy. He saw in the child's face when he first caught the omega’s pheromones, the crease between his eyebrows thinning as red eyes glanced down to meet gold.
“I don't know what's wrong,” the boy quietly responded, his light voice rough from heavy breathing. “I feel weird…” The boy trailed off, breaking eye contact as his cheeks flushed more. Dan Heng couldn't help but smile softly, the boy didn't know he was an Alpha. He couldn't just leave him here to suffer alone.
“It's okay, my name is Dan Heng, and I could help you if you'd like. How old are you?” He was curious, the boy looked like he should have already learned about secondary genders. The omega released another small amount of pheromones, wanting to coax the boy to answer his questions without issues.
“... I'm 12, and my name is Ren.” The boy finally said, eyes sliding back to look at Dan Heng. “You said you could help me, mister? Do you know what's wrong?” Concern was evident in Ren’s voice and Dan Heng reached up to place his hands on the boy's knees to ground him. Ren was hot to the touch, his warmth making the omega's heart rate spike for just a second. 12 was going to be presenting, that meant there was a strong likelihood Ren was a dominant Alpha, as the dominant of either secondary sex presented far earlier than their peers.
“It's nothing to worry about,” he responded softly, “what's happening is perfectly natural. Have you learned about secondary sex traits yet?” He paused, watching Ren and only continuing after he got a small nod from the boy.
“Okay good, what you're feeling right now is the start of a rut. It means you're presenting as an Alpha. I know it's scary and confusing but it's perfectly normal to feel that way your first time. I know I was scared myself when it happened, and I was close to your age too.” That was over a decade ago, but the 28 year old could still remember the fear he felt getting his first heat in public knowing what could have happened.
“Does that mean mister is an Alpha too?” Ren asked, and Dan Heng shook his head lightly. He saw the other frown, his pheromones lacing with anxiety once again. The omega simply released a stronger amount, watching the little Alpha’s eyes grow hazy and his pheromones calm. This wasn't the correct thing to do, but Dan Heng had never smelled such pheromones before and part of him didn't want to lose them. He couldn't just leave Ren here to suffer either, so it was only best that he as a dominant Omega helped him out.
“No, no, but that doesn't mean I can't help you. Firstly, we need to get you off the street, it's not safe for such a young boy about to go into rut. Will you let me help you?” With the question he released just another small amount of pheromones, being aware to not make them so strong he get the immediate attention of someone walking by. Ren's eyes clouded and he nodded, the Alpha falling susceptible to the enticing scent of an Omega without even knowing it.
Dan Heng smiled and got the boy onto his back, offering to piggyback him to the omega's house without any issue. Ren pressed against the collar on the omega's neck, breathing in deeply to absorb what of the older man's scent he could. It made Dan Heng chuckle and he released a faint yet steady stream of pheromones for the boy as they made their way to his house. His pulse was high, excitement creeping into his veins at the thought of helping this young Alpha through his first rut. Watching him come undone under his hands and he'd be completely lucid, able to use his pheromones as he liked. There was no way an Alpha who just presented would be able to do anything to him.
By the time Dan Heng got Ren inside his apartment, the young Alpha was finally entering his rut in ernest. Pheromones were starting to roll off the young boy in waves, the woody scent so alluring to the older omega. “Now now, let's get you someplace more comfortable,” Dan Heng cooed, carrying the boy to the bedroom. He lightly set him on his bed, smiling at the small whine the Alpha let out from being away from his name and pheromones. He moved quickly, going to get some water and anything else the young Alpha may need during his rut. The thought of condoms didn't even cross the omega's mind since he was unable to get pregnant unless in heat.
When he returned to the bedroom the air was heavy with the Alpha's pheromones, Ren had curled up with Dan Heng’s sheet, breathing in the omega's scent. It was adorable seeing him act like a nesting omega and he couldn't help but release a large wave of pheromones. He watched Ren gasp and move slightly, involuntarily rutting against the bed. The omega doubted the other had ever masturbated before, and he couldn't wait to help him through his first one.
“Mister, I feel weird,” Ren whined, his voice breathy and light. He was quick to move to the boy, running a hand through his hair.
“Shhh, it's okay. You're going to be fine, it's completely normal. You're becoming a man~” His words ended in a purr as he slid his hand down the other's face. “You'll let me help you won't you?” The question came his another release of pheromones and he grinned at the desperate look in the boy's eyes, his red eyes wet with tears. The boy was gone, Dan Heng knew he had no rational thoughts left in his young mind.
“Please-” that was all Dan Heng needed to lean down and kiss the boy. The little Alpha was completely compliant, opening his mouth and allowing the omega to ravage him. A thrill ran down his spine, very rarely was he larger than an Alpha and here was Ren, completely trapped under him as he shoved him flat against the bed. The boy whined against the tongue in his mouth, attempting to grind up but Dan Heng held him down with his knee. He kissed him like that until the boy drew blood with his nails and he relished in the coughing gasp from the little Alpha's mouth when he pulled away.
He was flushed himself, the Alpha's pheromones exciting him, but not anything more. He felt nothing of the fog that would roll into his mind when a heat approached. The boy squirmed under him, panting, tear stains on his cheeks. It was a beautiful sight, the omega ran a hand down the boy's cheek while releasing more pheromones. He wanted the other drunk on his scent, unable to think about anything but the omega on top of him. He slid his hand from the boy's face down his chest, enjoying the gasps from the contact. Dan Heng didn't even ask before slipping his hand farther, he knew the boy was too far gone to answer even a yes or no question.
What he felt made him pause, his heart hammering in his chest…there was no way this way right. He squeezed lightly and the moan from the boy confirmed his thoughts, the omega was shocked. He had never felt a cock so big from adult Alpha's, the fact this preteen was wielding such a weapon, it was perfect. Dan Heng couldn't believe how lucky he was, his lower belly growing warm already at the thought of it in him. It took little time to remove the boy's clothes and the omega relished in the body below him. The young Alpha lacked the typical physique of his secondary gender, his body not yet toned. Instead he had smooth pale skin, with a red flush over him from the rut. It looked delicious, the omega couldn't resist leaning down to lick down the boy's neck. The moan he got egged him on and he continued down, kissing and nipping at the boy's skin, relishing in every mark he left on the Alpha.
The Omega didn't go farther than his chest, sitting back up to finally get a good look at the boy's cock. It was massive, to say the least, already dripping with precum. He took it in one hand, unable to hold it all, and gave it a few strokes. The moans from the boy were music to his ears, the pheromones from the Alpha only getting stronger. He was shocked as it grew harder under his grasp, how big was it going to get? He was already worried he wouldn't fit it all, even now it would hit his womb with ease. He continued to tease the boy nonetheless, his own pheromones coming out with little control as the boy's cock continued to grow.
He felt his own slick soaking through his jeans and paused to remove his own clothes, his own dick hard and twitching. Ren was gone, his mind clouded completely from his rut, and Dan Heng didn't think much about the slow change in the Alpha's pheromones. He laid next to the boy, moving the small face to devour his mouth once again. Despite the slick the Omega knew he'd have to prep for this monster of a cock. With a free hand he reached down, his own moan reverberating into Ren's mouth as his finger slid into his wet hole. He removed his tongue from the Alpha's throat, shoving the boy's face into the nap of his neck as he fingered himself open. He felt the boy mouth at his collar as he rutted against him, the heat of the Alpha's cock making his lower belly throb.
He needed the cock in him, another moan leaving his mouth as he put in a third finger. He knew even four fingers wouldn't be enough for the boy's girth but he'd have to try. Dan Heng had been too absorbed in his pleasure to notice that the small Alpha had moved away from his nape and to his chest until he felt a warm tongue against his nipple. He let out a gasp, looking down as the Alpha as he suckled on his chest, occasionally biting and eliciting a moan out of the bigger man. Despite his prior confidence, Dan Heng hadn’t realized the slow creep of the preheat brain fog until it was too late. The Alpha’s pheromones were overwhelming now, overpowering his own and forcing them out of him. Dang Heng had never had this issue even with other dominant Alphas, something was different about Ren. It was too late for any hesitation though as slick gushed over his fingers and a whine escaped his lips. He pulled them out with a loud squelch and moved the Alpha off of him with more force than he thought would be needed. Ren’s expression was a wreck, tears still running down his face and drool dripping down the sides of his mouth.
“Alpha~” he purred, earning a growl from the small boy. He’d succumbed to his instincts, his pheromones fully releasing with no control. It was near suffocating and Dan Heng quickly rolled onto his knees, ass up and back arched. “Come here, you’ll feel better in no time.” He was still trying to hold control, but when he felt the boy’s cock slide against his ass he lost a part of his rationale.
”Please, put it in me” He begged, releasing whatever more pheromones he could. Ren was standing to get the best angle, the older man that much bigger despite being an omega. Dan Heng held a breath at the feeling of the tip against his hole, apparently he wouldn’t have to teach the young boy much. His instinct to breed during his rut was giving him all he needed to know. As it slowly breached him, a part of his mind broke, there was no way he was going to survive this. It was only the tip and it was stretching him to his limit, he wasn’t fitting the massive length in him.
He had no time to say anything however, his knees nearly giving out as the small boy forced over half of his massive cock in with a hard thrust, the tip already pressing hard against his cervix. The pain intermixed with pleasure and he felt himself cuming instantly, gasping into the sheet below him. It didn’t stop there as Ren slowly dragged out his cock before shoving it back in, hammering against the omega’s cervix and prostate. Dan Heng cried out in overstimulated pleasure, his cock continuing to leak as he was milked. Every hit against his cervix had the older man’s rationale leaving him as an unexpected heat shower himself.
This was going opposite of what he had wanted, but the fog filling his brain didn’t care. All it wanted was for him to be bred and every thrust against his cervix was edging on that wish. The boy’s cock was relentless, slowly bullying his cervix open. Dan Heng was gone as soon as it slipped into his womb, cuming hard as his heat fully set it. Ren could finally put his whole cock in, and with a hard thrust Dan Heng felt the air leave his lungs as his womb stretched to fit the cock. He was going to be bred by this boy and the thought filled him with nothing but pleasure.
Ren was a moaning mess above him, grabbing and digging his nails into Dan Heng’s hips with every thrust. The boy had never felt pleasure like this before but his instincts led him along, knowing the omega below him wanted nothing but to be fucked senseless. His thrusts got harder, pushing his massive cock as deep as it could go with his small frame. Dan Heng could barely keep himself up, his knees repeatedly trying to give out with every thrust. With his remaining strength he reached back and pushed against the boy, eventually getting him to still. The omega could now feel every inch of the boy’s cock as it twitched within him. He knew he’d be unable to get the Alpha to pull out and grabbed his hips, slowly coaxing him to his knees and as flipped onto his back.
From this position he could see the massive bulge of the boy's cock, it distending his stomach out in a way that shouldn’t have been as hot as it was. The overwhelming urge to feel it fill him, to knot him, overtook Dan Heng’s thoughts and he grabbed his legs, pulling them to his chest. Ren needed no instructions, quickly returning to a brutal pace as he fucked the larger man. His small hands came to rest near the omegas, his nails digging into his thighs as he held on. He was hitting deeper in this position and Dan Heng was gone, no thoughts left in his head but the urge to feel full of his Alpha’s cum.
Strings of words left his mouth, forming no coherent sentences as he begged to be knotted and filled. Ren was crying from pleasure above him, his throbbing cock the sign of his incoming release. Dan Heng met him halfway in a slobbery kiss, the Alpha’s extended canines nicking his lips and making him bleed. The taste of his blood only made them both moan as Ren’s thrusts become inconsistent.
“Yes, yes, inside me!” Dan Heng nearly yelled, wrapping his arms around the small boy. It only took two more thrusts before he felt the boy release, filling his womb with hot cum. It was more than he was expecting, his belly bloating more as rope after rope of cum shot into him. He came for the third time, his dick hurting from the number of releases. His brain was mush, but that didn’t stop an alarm bell from ringing when he felt Ren start to thrust again. He couldn’t take more, but his pheromones screamed the opposite as the Alpha started up a second round.
He could feel the weight of the cum in him, his belly shifting at every thrust of the Alpha’s cock. It was too much for him and he felt his consciousness slipping as a 4th orgasm suddenly ripped through him. He could do nothing his accept the brutal fucking as he lost consciousness.
When he came to, he was still being fucked, Ren’s cock relentlessly pounding into him. He wasn’t sure how long he’d been out, but by the size of his stomach the boy had to have cumed at least two more times. The sheets were soaked in escaped cum, as some leaked out with every thrust. Dan Heng was in a state of permanent overstimulation, his cock still rock hard despite the amount of times he’d cum. He knew he was pregnant, there was no way he wasn’t with the amount of cum in him. The thought had sizzle pheromones spiking and he heard his Alpha growl as his pace pick up.
The scent glands at his neck throbbed and he reached a weak hand up the pull at his collar. He needed the boy to bite him, to make him is bitch and breed him like this over and over. He could care less the boy wasn’t even out of middle school, he knew he felt the same from the pheromones. This was their overlapping rut and heat talking, but that meant nothing to Dan Heng’s fucked silly mind. It took him a moment to get the collar off, but as soon as he did the boy above him halted his movements, forcing the Omega under him back into their initial position with little resistance. Dan Heng had no strength left to hold himself up, but the Alpha pulled at his arms, pulling him up so he could mouth at his nape.
The angle was brutal, the omegas cock being milked with every thrust violently pressing against his prostate. He was gone, his brain utterly destroyed from the pheromones and the feeling of his Alpha’s cock. He wasn’t even moaning anymore, unable to make any noises but pathetic gasps as teardrop rolled down his face. This 12 year old was going to take him as his mate and he wanted nothing else but to bred by his cock.
As Ren snuck his teeth into his neck, a scream left his mouth from the pleasure of their pheromones intertwining permanently. The shared feeling of ecstasy reached a new peak and Dan Heng felt what he’d been wanting this entire time: his Alpha’s knot. It pressed into him as he was stretched to the utter extreme and he was filled once again with another load of cum. This time it didn’t stop like before, release after release continuing to stretch his stomach even further. He had to have looked months pregnant by now, the weight in his womb pulling him towards the bed. Not one drop could escape with the knot and he was forced to take all of it as his mind broke. Ren licked at the mate bond as he continued to cum in his omega, the young boy unaware of what was truly happening, knowing nothing except the discomfort he felt from his rut was finally starting to subside.
Dan Heng once again fainted, his last thought nothing but pure bliss. He’d come to later, his Alpha asleep next to him and cock still deep in him, the small boy attempting to hold the omegas cum swollen belly. He should be concerned, having been mated by a boy who only just presented, but he felt nothing but content. He wouldn’t be able to live without the small boy’s cock, and he could see himself like this over and over; either full of cum or pups. He couldn’t wait to watch his Alpha grow up and be able to live their life together as mates.
