Than!

Thanatos turned his head from his spot on the surface, just finishing reaping the soul of a soldier in Ares' war. He’s become accustomed to being summoned ever since he bestowed the prince with his childhood keepsake. It was reassuring knowing that Zagreus brought it with him on his ever repeating journey to the snowy landscape of the surface, so they could be connected no matter how far they were from each other.

Smoke swirled around Thanatos and he teleported to wherever Zagreus was fighting off the blood thirty shades of the underworld.

Though that’s not where he appeared.

He was floating above the carpeted floor of Zag’s room, not a musty chamber of Tartarus, the blazing heat of Asphodel, or even the lush meadows of Elysium. Thanatos was confused, why had he teleported there instead of a grueling battle? Though he loved spending any time he could with the heterochromatic prince, getting sent back to the House when he was absent wasn’t ideal with the amount of work he had on his plate.

Just as he was about to teleport back to the surface, a throaty moan broke the silence hanging in the air.

Thanatos turned towards the bed to take in the sight before him.

Zagreus was stripped of his red chiton and leggings, naked against the soft blankets of his bed. His laurels were askew and his face was flushed, the pink hue crept down his neck to his chest. It was only then that Zag’s whimpers weren’t the only other sound in the room. Wet squelches reached Than’s ears as his eyes landed on the prince’s hands. One hand between his legs, three fingers thrusting in and out of his slick hole, and the other hand stroking his leaking cock in tandem with the movement of his wrist.

Another moan rang through the air and Zagreus made eye contact with the god of death.

“H-hey, Than.” Zag greeted shakily. He continued pushing his fingers deep into himself while he watched Thanatos rake his eyes over his exposed form.

“Zag, you--”

“Yeah,” Zagreus cut him off, “it came early this time, m-my heat, I mean,” he let out a squeak when he brushed his fingers against his prostate. “I wasn’t sure if you’d hear my call.”

Thanatos thought that was ridiculous. He had promised him that he’d always be there for him, no matter what.

“Zag, you know I’ll always be there to aid you,” he let his feet hit the ground and stepped beside the bed where the omega’s scent was much more potent; surprisingly, it wasn’t the first thing Thanatos noticed when appearing in the bedroom. It was thick and heady as it flooded Than’s senses, his fingers twitched and his willpower was draining rapidly.

“T-then help me already,” Zagreus whined as a rush of slick dribbled from his wanting hole and pooled onto the bed.

“Blood and darkness, Zag,” and that was the last shred of restraint that Than had in his usually stoic personality. His scythe went up in a poof of smoke and he quickly stripped himself of the offending fabric that kept him from his omega. “You have no idea what you do to me.”

“I might have an idea,” Zag’s eyes dropped to Than’s thick cock, the knot already beginning to bulge at the base. His mouth watered and the bed dipped under Than’s weight as he moved between Zagreus’ soaking thighs.

Than gently removed Zag’s fingers and pressed the head of his cock to the stretched hole. If anyone were to walk in they would have no doubt that Than wouldn’t fit. Not only was Thanatos long, his dick had a sizable girth that complimented it nicely. Nicely for Zagreus, at least.

After what felt like an eternity, Than pushed his hips forward, earning a cry from the underworld prince. No matter how many times they copulated, the stretch of Than’s cock pushed out the most embarrassing noises from the man beneath him - and he loved every second of it.

“Fuck, Than. You’re so big, stretching me out so good,” Zag cried, even though only half of Than’s cock was inside of him. More pheromones filled the air from the swollen glands that sat against Zag’s neck.

Thanatos groaned and brought his head down to lick against the tender skin beside his collar bone. Zag keened and threaded his hands into silver hair which only encouraged the alpha’s assault on his throat.

“Ahhah, Than, I need more of you, please I need more, more of your thick cock inside of me.” Zagreus was always a talkative lover in bed, but he was exceptionally loud during his heats when the haze focused his thoughts only on Than and being properly fucked and filled.

Thanatos smiled against Zag’s neck and relished the sting of his hair where he gripped, along with the sobs that left Zag’s pretty mouth. Zagreus let out a shaky sigh once Thanatos was fully sheathed inside his tight heat. He had only just entered him and Zag already felt taught as a bowstring.

“That’s it, f-fuck Than,” Zag weakly attempted to thrust himself onto the cock inside of him, wanting more and more as the seconds flew by. Thanatos knew how needy Zag was in heat so he decided not to deny him release for long.

Hands slid up the back of Zag’s thighs all the way to the joints of his knees. Zag’s breath caught in his throat when Than pressed them down until his knees were touching the bed. The corners of Zag’s lips upturned into a giddy smile knowing what pleasure was to come.

Both of them moaned when Than started dragging his cock in and out of Zagreus, little breathless whimpers that came from Zag were music to his ears. Zag tilted his head back further into the pillow, closing his eyes at the tremble of his thighs and the feeling of pleasure running through his blood like electricity. Than scraped his teeth and licked at the new love bites he left on the prince’s skin for anyone to see. Generally, Thanatos was hardly described as possessive. He went about his days and night simply taking souls ready to be guided to the underworld for eternity, but when it came to Zagreus, a man who was as bright as the sun, something inside of him just wanted to protect him and keep him from harm.

Than picked up the pace, slamming into Zagreus with an aggressive force and watching the slick coat his cock, making a mess between Zag’s legs.

Thanatos marveled at the sight before him. Watching his cock disappear deep inside of his prince with each shove of his dick, the hot whines that accompanied them. Zagreus was in absolute bliss, his eyes heavy and lidded, his own cock hard and endlessly dripping onto his belly.

Without warning, Zagreus came wordlessly onto his stomach as he shuddered through his first orgasm. Thanatos knew better than to slow down. He often recalled Zagreus’ first heat they spent together and how the omega practically started crying and begging for him to keep moving. So Than decided to do the opposite and only began to fuck into him faster and deeper. More weight was put onto the crease of Zag’s knees, effectively bending him in half to the highest degree, allowing for Than to reach spots he hadn’t before. Zagreus reached up to wrap his quivering arms around Than’s neck, bringing him down into a bruising kiss, tongue, teeth, and all.

“Oh, fuck, Than, you ah fuck me so good. So deep, I feel so full when y-you’re inside of me,” Zagreus breathed against Than’s lips, licking them only to connect them once more before sliding their hot tongues against each other.

Thanatos felt another gush of slick against his dick and groaned, only now noticing how much slick Zag was producing. He trailed his lips from Zag’s lips down to the skin of his neck, right beside the bonding mark he gave him long ago. Zagreus unconsciously bared his neck even more for him, wanting to be bitten again with short uneven breaths.

“Do you like this position, Zagreus?” Than asked while pulling away to get a good look at his omega. Zagreus nodded frantically, his eyes fluttering from a particularly good thrust.

“It’s just - you’re just hitting so deep, it's like, it’s like,” Zagreus bit his lip, more slick sliding down the curve of his ass.

“It’s like what, my beloved?” Than rolled his hips, trying to coax out a response only to get a grunt instead.

Zagreus swallowed down a groan, watching the way he was being penetrated over and over again. He loved watching himself get dicked down, and maybe they’ll do it in front of his mirror sometime.

“It’s like- it’s like you’re going to k-knock me up.”

“Blood and darkness,” Something about the way Zagreus was looking up at him with mismatched lust-filled eyes and how his lips were parted, little sounds bubbling from his throat, brought Thanatos to the edge in a blink of an eye. “Would you like that, Zag? Would you like me putting a godling into you?” Than’s thrusts became more erratic at an almost punishing pace, the whimpers coming from Zag were coming out rushed and uneven.

“Ah! Yes, Thanatos, ahh, p-please,” Zagreus’ body was shaking at the force of each thrust, his laurels finally losing their place atop Zag’s hair, “Than, please please, I need your knot, I want your knot so badly. Fill me up with your cum.”

“You want godlings that badly?” Than asked, pressing Zagreus’ knees further into the bed and hitting deeper and deeper inside of him. Zag could only choke out a mewl as the head of Than’s dick kissed up against the spot inside of him that made him see stars. He nodded his head, glancing down to where his body met with Than’s before tilting his head back up to meet his eyes. Clear slick continued to be pushed in and out of his stretched hole and it rolled down the back of this thighs.

“Y-yeah, I want them, I want them so much, please, f-fill me.” Thanatos wasn’t sure if he meant with godlings or with cum, but both would happen so long as Zagreus asked for it.

It only took a few more thrusts until Than push his way back into Zagreus and came hard, knot expanding to form a seal to prevent any cum from escaping. He bit into the mating bond on Zag’s neck and had the prince crying out in pleasure, cumming again onto his stomach in spurts. Zagreus could feel the sheer amount of cum inside of him being plugged up by Than’s cock, sating his heat for now.

Both of the men were breathing heavily, and Thanatos let go of Zag’s legs in favor of lying down on the bed next to him with their bodies still connected. Despite the drying cum on Zagreus’ chest, Than gathered him up in his arms anyway to properly embrace him. He set the laurels back neatly on Zag’s head and gave him a kiss, feeling Zag nuzzle up against his chest.

“Hey, Zag?”

“Mmhm?”

“Did you mean what you said, you know, about having godlings?”

“Oh, I um, yes? I’m sorry, Than, I wasn’t sure what came over me. Well, okay, I do know what came over me, but I didn’t mean to put any pressure on you or anything.”

“It’s okay, Zag. I’m not opposed to the idea myself.”

“Really? Oh, that’s good, I was afraid the idea may be off-putting is all.” Thanatos felt Zagreus’ smile against his chest, happy and content, at least for now in between heat spikes.

“Not at all, it’s something that I’ve thought about from time to time as well.”

“Oh, that’s wonderful! I love you, Than.” Zagreus turned his head up to Thanatos in a quick kiss.

“I love you too, Zag.”

Chapter Text

Zagreus rolled over at the familiar feeling of arousal stirring him from his slumber. After their first fuck session of Zag’s heat they both went to sleep to store up energy for his later bursts of need. Gods of the Underworld, or gods in general, rarely indulged in the act of sleep and it was only when they would go into heats or ruts when they slept to their heart’s content.

He looked to Thanatos’ form beside him, Death Incarnate facing Zagreus in a sound sleep. Gods above he was beautiful. The sharp cut of his hair fell softly to frame the strong angle of his jawline, feather soft silver eyelashes bordered piercing amber eyes; not to mention his body. He was built like, well, a god. Broad shoulders and powerful muscles that were perfect for pulling Zagreus into eager hugs after he returned to the Underworld (amongst other things).

Just looking at the man before him made Zagreus horny, thinking about how good his heavy cock takes up the hot space inside of him. He moaned inwardly and absentmindedly brought his fingers to his still dripping hole. Zagreus knew that wouldn’t be enough to satisfy him, which led his eyes to wander down Thanatos’ body to the bulge beneath the sheets.

With gentle hands, Zagreus pressed Than’s shoulder to have him laying flat on his back. Zag bit his lip trying to think straight.

He said it was alright to… use him, Zagreus remembered, the familiar haze of arousal settling into his vision. He and Thanatos had that conversation before, that if Than was sleeping Zagreus was free to… relieve himself on his mate. It really is okay, Zagreus, it doesn’t bother me and I’d rather you not be in discomfort, Than had told him.

Zagreus lifted his trembling arm and peeled back the blanket on Than’s waist down to his knees. He was still naked from earlier and already half hard, knowing his omega was in heat and had to be ready to fuck him at a moment’s notice. The prince licked his lips and lowered them down to the cock in front of him.

Thanatos was a colder god in comparison to everyone else in the House and it certainly translated to the temperature of his body. Except, Zagreus had noticed, his dick. Zag pressed his plump lips to the warm head, eyes flitting to Than’s face for any sign of consciousness. When he saw none he sunk down deeper, salivating all over the delectable hardening length. Zagreus inhaled the dizzying scent of his alpha’s musk and felt himself release pheromones, wetness leaking between his legs as a result. 

He mewled around the cock down his throat, licking up against the hot curve of his shaft. If Zag wasn’t experiencing his heat he would’ve loved to suck Than off to completion, swallowing down his cum like a good boy. Unfortunately, that would have to wait until another time when Zag’s insides weren’t aching with need. Fresh slick and cum from earlier dribbled down his thighs and Zagreus knew he needed to be filled soon, lest he go insane. 

Zagreus sped up the bobbing of his head on the cock in his mouth, laving his tongue across the head and down the shaft, feeling the thick veins squeeze into his mouth.

He popped off with a wet gasp, his breathing already becoming labored the more this wave of heat set in. Than’s dick stood tall and fully erect, ready to take its place inside of his mate. Zagreus shuffled to straddle Thanatos’ hips, his hole drooling and begging to be filled.

It was too late to take things nice and slow, so Zagreus sheathed himself onto the cock beneath him in one fluid motion, a low groan passing his lips. The feeling of being filled by dick felt heavenly when his mind was clouded with the need to be fucked. It wasn’t that Thanatos felt any less good when he wasn’t consumed by the visceral need to reproduce, but finally being filled was euphoric.

He refocused his eyes on Than’s face, but the god was still fast asleep and unmoving.

Bracing his hands on solid abs, Zagreus pulled himself up with wobbly thighs and began thrusting himself up and down on his boyfriend’s shaft. 

“Ngh, ah, f-fuck,” Zagreus bit out, bouncing on Thanatos in a steady rhythm. Slow slapping sounds rang through the air each time Zagreus’ ass met the flesh of the strong dark thighs beneath him.

Though fucking himself on his alpha helped with his heat, the tingly warmth under his skin refused to subside, making Zagreus feel anxious in the pit of his stomach. The initial shock of warmth from Thanatos’ cock faded, disappointment creeping into Zag’s chest. What he really needed was to be pounded relentlessly and knotted to be truly satisfied. He needed Thanatos to put as much cum as he could inside of him as possible.

He whimpered and felt tears start forming in the corners of his eyes. Zagreus hated crying during his heat, where everything was more intense and was hyper-sensitive to everything around him. Somehow it was worse to have Thanatos there and not having him fuck into him. He loved being around the god of death, but having him there sleeping and doing nothing to help Zagreus with his heat was almost unbearable. 

Any other time he would be just fine, riding on top of Thanatos was an activity that Zagreus was quite fond of, watching the way Than’s face twisted in pleasure below him while he took the reins. Though heats of gods were infrequent, Zagreus didn’t particularly mind them except for times like these where he felt at a loss of what to do about himself. His body felt hot, his skin crawled with tendrils of warmth that clawed at his insides.

And it wasn’t as if he wasn’t horny anymore, he still felt himself trying to squeeze onto Thanatos to get as much delicious friction as he could. Just when he was about to switch positions, strong hands suddenly slid up Zag’s waist to cup his flushed face.

“Ah! Than, you’re awake.” Zagreus looked at him teary-eyed and Thanatos thumbed them away, his hand lingering on Zag’s warm cheek. There was a bit of a sad edge to Than’s eyebrows as his eyes wandered over his mate's tear stained face.

“I’m sorry, Zag, don’t cry. I’ve got you now.” He took Zagreus’ hand in his and kissed his knuckles in a silent promise to satisfy him.

Than settled his hands back on the prince’s waist to barely lift him off his cock only to slam back inside.

“O-oh, ahh haah Than!” Zagreus felt his brief sadness quickly leave his body to make space for intense arousal bubbling within him. This was exactly what he needed, Than’s alpha cock messing up his tender insides, feeling his slick mixing with the cum from earlier inside his wet, messy cavern.

Now that Thanatos was fully awake and conscious of the current situation, he was able to relish in the feeling of Zag’s tight walls move and constrict around his length. He had to be careful about staying inside since the slick and cum mixture made it easy to slip out of Zagreus’ sopping wet hole.

While Zagreus was moaning above him, Thanatos rubbed his palms on the smooth muscle of the prince’s waist, watching at the way he twitched with each thrust of his hips. Than’s hands wandered across Zag’s chest and down to the taut skin of his stomach, pressing down lightly to almost feel himself through the muscles there. He wondered what it would be like when Zagreus was full of godlings, if his belly would soften to accommodate them or if his abs would remain as they were.

Gods, Zagreus was the sexiest man alive and Thanatos felt lucky enough to be graced by his presence, let alone be his mate.

Zagreus looked quite happy being fucked into oblivion on top of Thanatos. His mismatched eyes were lidded and delirious with lust, a dazed half-smile appeared in between shuddering moans of pleasure. Every part of Zagreus’ expression told Thanatos how much he enjoyed being filled over and over; from the bewitching gaze that he held between them, to the rough sounds that passed through his bitten lips.

Zagreus went to fist his own dripping cock but was immediately halted when his wrist was caught by Than’s hand. His eyebrows quirked up, obviously confused.

“Than, wh--”

Before Zagreus could say another word he was pulled off Than’s cock and was pushed face-first into the pillows of the bed. His hips were up and Than slid right back into the tight heat before his mate could protest. He draped himself over the prince’s back, his breath hot against his ear.

“Let me take care of you, Zag.” He kissed Zagreus on the neck and fisted his dripping cock, earning a stifled moan.

“O-oh, that’s, ah ! Ah, ah mph--!”

Thanatos made sure to keep pounding hard into Zagreus while he was stroking him off, his thighs and ass shook with each punishing thrust.

The noises Zag was making were absolutely erotic. His loud cries of pleasure were muffled by the plush of the pillows at his face, the squelching and steady slapping sound of where they were connected only drove him further to the edge. 

Saliva was dripping from the corners of Zagreus’ pretty mouth, his body forgetting how to do anything except taking Than’s cock and cry out against it. Strings of little ah ah ahs were pushed from his lungs, his eyes losing focus each time Thanatos slammed his cock head onto his prostate.

“T-Than, more, more please, I- ah! I’m yours, I’m yours--” Zagreus grasped at the bedsheets weakly and spread his legs ever so slightly. A particularly mean grind to his sweet spot had Zagreus gasp in surprise, his body shaking against the stimulation and his head going fuzzy. “Oh oh oh, Than, I’m--!”

That’s all Thanatos needed to hear before sinking his teeth into the already bruised bond on Zag’s neck, feeling him squeeze and clench around his cock in a powerful orgasm. His eyes rolled back into his head and painted Than’s hand white with his cum, only feeling the edges of overstimulation when Than didn’t stop stroking his dick.

Thanatos was barely able to stave off his own orgasm. Watching Zagreus unravel from being fucked good and hard would always be the most arousing thing to the god of death. He needed to know if Zagreus needed to be fucked more before he popped his knot.

“Zag, do you want to keep going or--”

“Cum in me,” Zagreus replied quickly, looking over his shoulder to gaze into Than’s golden eyes, “I-if we want godlings I need to stay f-full of your cum, right?”

He was going to be the death of Thanatos one day, which is ironic all things considered. Thanatos groaned and pressed himself the deepest he could inside of Zagreus, to make sure none of his cum would escape from his needy hole.

“O-oh, fuck yeah, so good. I love you, I love you so much, Than, give me your cum, your children please please please!”

Thanatos bit down on Zagreus’ neck once more before thrusting his knot into him. He growled against Zag’s neck, pinning him to the bed with his body and their fingers interlocked, pumping his impressive load of cum deep into the omega below him. A violent shudder wracked through Zagreus’ body as he came down from his high, whimpering against the pillow at his face.

They stayed in that position while the two of them caught their breath and began to relax from the heavy exertion. They were both hot and sweaty, slowly coming back to earth.

Zagreus let out a sigh of satisfaction, wiggling his hips to feel Thanatos’ softening length and the cum move around inside of him. He pushed himself up with his elbows and craned his neck around to kiss Than, smiling against the warmth of his lips. Thanatos returned the kiss and wrapped his arms around Zag’s middle. He flopped them both onto their sides, Than effectively spooning the other.

“Feeling better, Zag?” Thanatos nuzzled his face into the crook of Zag’s neck, nosing at the sensitive scent gland there. 

“Very much so.” Zagreus breathed, his chest rising and falling from exhaustion. His body felt pleasantly wrung out, basking in the comforting warmth radiating off of his skin.

“You should rest up, your heat will most likely start up again in a few hours,” Thanatos kissed the space behind Zag’s ear, “And don’t be afraid to try and wake me up.”

“Mhm, I will. I love you, Thanatos.”

“I love you too, Zagreus.”

Chapter Text

It was Thanatos’ turn to wake from his slumber much like how Zagreus woke up without him mere hours ago. He sat up in the bed and ran a hand through his slightly sweaty hair. His head felt light and his dick was definitely hard, the scent of his mate sharp against his nose. The world around him felt slower but not sluggish, merely allowing him to take in the senses around him. 

He was going into rut.

It made sense, if he thought about it. Thanatos assumed part of it was because Zagreus has never asked to have children before and having him in heat and begging to be filled with cum over and over definitely did something to him.

“Just so we’re clear if you need to fuck me while I’m sleeping, I’m more than okay with that,” Zagreus grinned with a wink.

The prince was fast asleep beside Thanatos, his breathing even and soft. He was absolutely exhausted from the number of orgasms he had only hours ago, the purple bruises on his neck stood out to show for it.

Even though he was given explicit permission to have sex with him while sleeping, Thanatos didn’t want to wake him up from his well-needed rest. He would just have to wait it out until Zagreus woke up and then he could fuck him again and again to satisfy both of them. Yes, that was a good plan.

“Mmn, Than…”

Thanatos felt his fingers curl into the sheets beside him and brought his eyes to Zagreus’ sleeping face where it was half-buried in the pillow. From what he could see, Zag’s eyebrows were upturned as they usually were when he was being pleasured, and his lips were parted to let the smallest of sounds escape.

The sweet smell of Zagreus’ pheromones trailed around the room until they were all that Than could sense. The scent was almost suffocating but it was something that Thanatos was more than willing to be drowned by. He brought his hand to his neck where his own scent glands lay beneath his skin.

He’s reacting to my rut.

Zag’s hips twitched against the bed, his breath hitched when more of Than’s delicious musk touched his tongue through the air. Thanatos gripped the sheets tighter, trying to keep his resolve of letting Zagreus rest for at least a little longer. He inhaled deeply to try and clear his head of the fog that clouded his mind.

Bad idea. 

The room was already swamped with the needy air of his omega and breathing it in was sweeter than the most potent ambrosia. Thanatos felt his cock leak precum, making an obvious stain on the blanket draped across his lap.

“Th...Than, please…” Zagreus mumbled, a tiny gasp accompanying his almost silent words. He rolled over and the thick aroma of slick wafted up from the covers.

Fuck it, they were gods. They have plenty of time to sleep.

Thanatos ripped off the blankets from their bodies and moved towards his lover. Zagreus whimpered when he felt Than nose at his swollen scent glands and bonding marks. He licked broad strokes along the column of his neck, tasting the salt of his sweat and the sweet of his skin and eventually planting kisses there.

Warm hands found their way across Zag’s chest, gently kneading at his relaxed muscles and feeling the steady beat of his heart. Than’s fingers traveled down to the skin of his belly before stilling the flat of his hand against it. A vision of Zagreus happy and full of godlings crossed his thoughts, and he couldn’t help but growl possessively.

Before he had any time to think, Thanatos positioned himself snuggly in between Zag’s thighs with his cock hard and heavy laying against the junction of Zag’s leg and hip.

Zagreus whined when Than’s cock came into brief contact with his own, a single trail of drool flowing from the corner of his mouth onto the pillow. Pre-cum from their dicks pooled in the dip of Zag’s pelvis and Thanatos had to fight the urge to dip his fingers in it and smear it across Zagreus’ body.

He was losing himself quickly to his rut, the overwhelming need to breed his omega taking over his body.

Thanatos pulled his hips back and slid into Zagreus’ hole with ease, still slippery and open from the cum that clung to his walls that filled him up. He groaned at the warmth surrounding him before giving an experimental thrust to see if he roused his sleeping beauty; luckily, he didn’t stir except for the barely-there moan that slipped past his lips. Zagreus’ eyes remained closed, shielding Than from his melting gaze.

Another thrust of his hips and still nothing beside the squelch of cum and slick. Thanatos curled Zag’s legs up towards the bed, leaning over his chest to kiss his pecs and suck marks into his supple skin.

The scent coming from Zagreus was utterly intoxicating, pulling Thanatos further into the haze that consumed his mind. He drove his pulsing cock deep into Zagreus who was still unmoving from his rest.

Even in his sleep, Zagreus was a sight to behold. His soft lips parted just enough to get a glimpse of his pink tongue hiding away in his hot mouth, the quickened speed of his breathing was brought about from Than penetrating him over and over. Zag’s hair was still a mess, his laurels long gone and forgotten somewhere on the floor amongst the rest of their garments.

Thanatos brushed the pads of his fingers across Zagreus’ jaw and swiped his thumb over his plump bottom lip before dipping it into his mouth.

“Mnh…” a fleeting whimper came from the prince as he unconsciously laved his tongue against the rough pad. Thanatos felt himself grow harder, grinding deep inside the liquid fire of Zagreus’ insides.

It felt strange, using Zagreus’ pliant sleeping body to satisfy himself. Merely as a toy to fill over and over with sticky cum. Than gasped when he suddenly felt Zagreus clench around him, trying his best to keep Than’s cock deep inside of him, like he couldn’t bear seconds without him.

“You crave me even in your sleep, don’t you, beloved?” Thanatos whispered, moving his hand to brush his thumb across Zag’s tongue and sharp canine teeth. He replaced his thumb with his index and middle finger, rubbing them incessantly against his wet tongue.

Zagreus seemed to love having his mouth filled with something. He gently bit down, his breath hitching when Than pushed them deeper inside of him, all the way up to the knuckles on his hand. His breathing sped up and he rolled the wet muscle along the slender digits in his mouth, and Thanatos let out a low groan. He swirled his fingers around, squeezing the muscle before he withdrew them from his mouth to skim along his bottom lip, leaving it shiny and glistening with saliva.

He slipped his hand away from Zagreus but not before dragging the moist fingers against the side of his cheek.

Zagreus must have been incredibly tired, having not woken up yet from the rough manhandling. Though he did need his sleep, Thanatos silently wished he would wake up so he could listen to the saccharine sounds of his moans against his ear and feel the nails digging into the meat of his back.

Thanatos braced his hands on Zag’s hips and leaned down until their foreheads touched, their breath mingling together. He captured their lips in a searing kiss before pulling out and thrusting right back into Zag’s abused hole.

“I’ll fill you up nice and taut, I know you’ll love having godlings. I’ll fuck you full of my cum even when you’re filled to the brim. Keep you nice and happy on my cock.” Than groaned, dizzy with lust with his mind only on breeding his omega full of godlings.

Something inside of Thanatos felt unchain, unhinged from his usual ruts. Now that he knew Zagreus had a desire for children, he couldn’t stop himself from plugging him up with cum even if he wanted to. Zagreus had him wrapped around his finger and they both knew it.

Dark eyelashes fluttered before relieving orbs of red and green, pulling a small smile onto Than’s face. Zagreus blinked a couple of times to remove some of the sleep from his vision. He gasped abruptly, now fully aware of the hard cock plowing into his hole over and over.

“You’re ah , y-you’re in rut,” Zagreus slurred, his voice gravelly from sleep and crying out, “I, ah , thought this was a dream, you know?” he instinctively locked his arms around Than’s neck, keeping their faces close, “I’m so glad it wasn’t,” Zag pressed their foreheads together, whispering, “Perfect for you to breed me.”

Lips met lips once again in fiery passion, the two men moaning and huffing hot breaths when their lungs screamed for air. Than slid one hand up Zag’s chest to thumb at an exposed nipple to pinch and squeeze at it, mesmerized by the high-pitched noises that filled the room shortly after.

Thanatos kept up the pace, driving Zag’s hips down onto his cock again and again, wrenching sweet sounds from Zag’s lips. Old cum churned inside of Zagreus’ hole and spilled out onto the bed with every demanding snap of Than’s hips. It wasn’t long before Zagreus could be filled again.

“Fuck, Zag, you take me so well, you’re clenching around me so tightly I can tell you’re close,” Than felt the gradual bulge of his knot catching on Zag’s rim, no doubt red and swollen from the constant stimulation, “You’re going to be so full with my cum there’s no way you won’t be knocked up by the end of your heat.”

Zagreus could only whimper in agreement as he took Than deep deep inside, his walls tightening on instinct. His thighs trembled from where Thanatos held him, slamming into him with purpose. Hot tears of pleasure dripped down Zagreus’ flushed cheeks to compliment his fucked out expression. His exhausted body couldn’t keep up with the aggressive push and pull of his body on Than’s cock.

“Zagreus, darling, love, you smell so good. You’re beautiful, so perfect, just perfect,” Thanatos eyed hungrily at the purples and pinks that bloomed from Zag’s neck and shoulders. He bent down to kiss the perfect teeth indents that shown through the dusty colors. Zagreus mewled when the familiar hot tongue pressed flat against the bites and bond mark on the side of his neck, relishing in the tingling feeling going through his veins.

“You’re mine, Zagreus. I’ll never let you go.” Thanatos declared against his skin. He let his hand move from Zag’s chest in favor of wrapping around his leaking, sensitive cock. The eratic jerks of Than’s wrist had Zagreus tumbling towards the edge.

Zagreus let out a strangled cry, his whole body trembling like a leaf, “Than, oh Thanatos,” he felt the pit of his belly draw tight with each drag of Than’s cock, his vision going white, “I’m-I’m cumming--!”

Than growled and sunk his teeth deep into the sensitive bond before finally locking their bodies together with his inflated knot. Cum flooded into Zagreus who came so hard he could barely remember his name. He could still feel Than cumming inside of him a minute later when his head began to clear itself. Alpha ruts sure were something to behold.

Zagreus felt the pleasant sensation of warm lips press gently to his throat, more airy kisses being smooched up to his cheeks until his eyes met a soft gold.

“Did you know you’re the most beautiful person I’ve ever laid my eyes on?” Than brushed the sweaty bangs away from Zag’s forehead.

Zagreus chuckled breathlessly, “I do believe you’ve told me once or twice, yes.”

“Oh good, it would be tragic if you weren’t aware.” Another kiss made it to Zag’s temple. And another, and another until tiny kisses were placed thoughtfully all over Zagreus’ mirthful smile, a jovial expression stretched across his face. Zagreus kissed him back before falling asleep in his arms.

Chapter Text

The fruits of their labor were rewarded because Zagreus’ heat soon subsided as an indication he had become pregnant with a little godling. Thanatos and Zagreus were overjoyed and celebrated with those within the House of Hades.

Most of their habits remained the same, Zagreus dashing around his father’s realm and up to the surface only to inevitably return to the pool of Styx (although, his runs had been getting slower due to the new weight). Thanatos continued his duties as Death Incarnate, reaping souls and sending them to Charon to be ferried down to wherever they were destined.

More time went by and Zagreus began to notice changes to his body. First, he noticed that his skin felt softer to the touch. Thanatos noticed it too and commented on it multiple times, his mind pleased at the supple skin of his mate. Second, Zagreus seemed to have a new craving for food on the surface. He rarely needed to eat outside of his little jaunts through his father’s domain, but now that a child was growing inside of him Zagreus would moan to Than about getting him “those red fruits that look like poms," amongst other things. And of course, Than would drop everything to make his mate comfortable and happy.

“These are good, what are they called again?” Zagreus bit into the red flesh of the fruit he was eating. He and Thanatos were lounging on their bed after their work for the day (night?) had been completed.

“They’re called apples. Sometimes they grow green." Than smiled softly, and rubbed circles into the hand that wasn’t holding the dripping fruit. Slowly Zagreus learned more and more about the surface, wishing to explore above without the restraint of the Styx at his neck.

Zagreus hummed as he munched in thought.

Thanatos closed his eyes, relishing in the comfort of the pillow beneath his head and the blankets at his back. The scratch of the wicker basket holding the rest of the apples was placed on the floor, and the bedsheets stirred when Zagreus shifted closer.

“Mmm, Than?” Zag’s expression changed from a moment ago, his eyelids grew heavy and the tiny bite to the side of his lip made him look all the more sultry. His demeanor changed from casually relaxing into wanting to be fucked then and now. Zagreus tilted his head playfully, dark soft hair hanging off his shoulder.

The air in the room slowly began to saturate with Zagreus’ alluring scent, something sweet and sticky; one might find it akin to the golden syrup he finds within the chambers of the Underworld. Thanatos made an attempt to sit up only for Zag to crawl up against his body, their noses pressed together and lips barely touching. Hot breaths mingled together before Zagreus’ pink tongue darted out to lick at Than’s bottom lip.

"Yes, Zagreus?" Thanatos couldn't help but ask, noting the shine of something behind his lover's eyes. It was obvious what he wanted, but teasing him was just part of the fun.

Zagreus drew circles with his finger along Than’s chest, the sweet scent strong against his skin.

“I think I’m hungry for something else,” Zagreus whispered before leaning in for a wet kiss. Pink flesh of their lips slid together, little moans crawled from their throats. Zagreus gripped at Thanatos’ chiton, lightly kneading his hands into the firm muscles beneath. He needed more contact, more of his body to be touched and held by the strong man below him.

Thanatos watched carefully when Zagreus reluctantly pulled away to strip out of his own clothes, leaving him bare for only Than to see.

Without the coverings of the red fabric, Zag’s stomach was much more noticeable. The amount of time for a god to be born was undeterminable, but one could tell Zagreus was somewhat far along due to the slope of his belly.

Thanatos sat up, quickly rid himself of his own garbs and leaned over Zagreus’ nude form.

They continued to share the passion between their breaths, saliva mixing together accompanied to the nip of lips and clack of teeth. Zagreus whined when Thanatos placed a hand on his belly.

“Than, please, I need you.” Zagreus choked out, his body trembled against the hard planes of the god above him. Slick leaked from the princes’ hole, desperately needing to be filled with Than’s hard cock. 

Despite the little one growing inside of Zagreus, his drive for kinky rough sex hadn’t dissipated in the slightest. In fact, Thanatos would even say he’d been looking for more sexual stimulation than usual. He would be roused from sleep by Zagreus clenching around his dick more than he could count on both hands.

Zagreus wasn’t even in heat, yet he was practically drooling for Death’s fat cock.

Thanatos slid a strong hand up the side of Zag’s thigh to where his hip met his pelvis, gently stroking the pale skin there with his thumb. He was already wet with arousal, the addicting aroma clouding Than’s head.

Than's fingers drifted lower and lower until they were met with Zag's hole already slick from his juices.

Zagreus curled his toes at the sensation of Than opening him up with thick fingers, already feeling the wetness of his hole leak onto the bedspread.

“Ngh ahm, Than,” Zagreus gasped when he felt Than’s knuckles meet his wet rim. Thanatos was tugged down again, his mouth being sealed with Zag’s as he continued to scissor and finger his pliant hole. It wasn’t too long before a third and fourth finger were pushed in alongside the first two.

Thanatos couldn’t understand how Zagreus was so loose under his fingertips yet so so tight inside. Each pump of his fingers had Zag paw at his chest and quietly beg for more. 

Watching his four fingers plunge in and out of the omega under him lit something inside of Than. 

“Do you think I could get my whole fist inside?” Thanatos murmured absentmindedly, thumbing the stretched rim that squeezed his fingers. Zagreus felt his insides draw tight, some slick squirted from between the digits filling him up. His mind buzzed at the idea.

“Y-yeah, but-” Zagreus arched his back at the fingers prodding his sensitive sweet spot, losing his breath and gasping wantingly, “B-but I want your cock now-,” he moaned again, “please.”

The hot sensation of pressure was at a standstill when Than removed his fingers from Zagreus’ hole. Thanatos kissed him on the forehead and positioned himself between Zag’s wet thighs, with his erection between them.

Zagreus let out a choked groan when he felt the head of Than’s cock gradually penetrate his soaked hole. Inch by inch, Zag took the dick inside of him. 

“You look lovely,” Than whispered. Zagreus felt fingers brush against the curve of his stomach, the touch light and delicate as if he were made of glass. The beat of Zag’s heart was interrupted by the thrust of the cock buried inside him. Zagreus gasped and loosely gripped at Than’s biceps, trying desperately to ground himself.

It was futile, however, because Thanatos, without missing a cant of his hips, reached for Zag’s wrists in one hand and pinned them above his head. He had no choice but to lay there and take the assault on his sensitive hole.

Zagreus cried out, loving the way Than bound his hands so he could fuck him as hard as he wanted without Zagreus wiggling too much. Each thrust caused shivers to run down his spine, Than’s cock making space inside Zag’s body.

The forceful drag of his cock bumped against Zag’s prostate with each punishing motion. Zagreus could feel each ridge of Than’s dick reach deep in his hole, poking and prodding at his sensitive spots. His toes curled on the bed and felt a dizzying heat begin to pool in his stomach.

The prince was so overwhelmed by his pleasure that he missed the way Than’s narrow eyes bore holes into his skin, observing each and every movement that wracked through his body. Zagreus moaned, his cries high pitched and begging for release. Thanatos was incredibly familiar with Zag and his body. He’d give him what he needed but not quite yet.

“Thanatos-?” Zagreus started, the steady slide of cock inside of him slowing into an almost torturous pace. He squirmed trying almost desperately for Thanatos to keep fucking into his tight hole.

“Blood and darkness, look at you,” Than let himself stare at the man he loved, taking in his beauty each and every time he laid eyes on him.

Zagreus sprawled out beneath him laid comfortably on the bedsheets and his head tucked into the fluffy pillows. His skin was glistening with a light coat of sweat defining his already prominent muscles. Zagreus writhed under the watchful eye of his lover, wishing that he would start moving again, because only so much blood was occupying the prince’s head to think by that point.

Tender fingertips skimmed down Zag’s side to the slope of his belly, proof of their union and undying bond together. Zagreus smiled knowingly and brought up his own hand to cup against Than’s cheek.

“Oh, Zagreus,” Thanatos leaned down and captured his beloved in his arms, holding him close to his body. His heart thrummed deep in his chest as he ran his hands up and down Zagreus’ precious stomach.

It was still surreal to Thanatos, that the man he adored for the longest time would be carrying his child. Each tender touch and lopsided smile only pulled Thanatos deeper into love with Zagreus. Who knew that the god of Death would form such a bond with the son of Hades?

Thanatos gradually thrust his hips forward into Zagreus, listening to his breathy moans beside his ear. Zagreus scraped his fingernails into the muscles of Than’s back before pressing his face into the crook of his heated neck. He inhaled the thick comforting scent and kissed along the column of his throat.

“Mmm Than,” Zagreus purred, squeezing around the erection hitting each of the nerves that made his head numb with ecstasy. He rolled his body against Than’s chest, his breath hitched when he felt Thanatos wrap an arm around his waist and pull him closer.

Zagreus pressed his mouth back into Than’s neck to stifle his weak moan when his cock was squished between the plush of his stomach and the hard plane of Than’s abs.

His body felt like it was on fire from the intense stimulation to his greedy hole and dick. The grunts that came from Thanatos didn’t help him either, only spurring him closer to orgasm.

“You look so good like this, Zagreus,” Thanatos licked along Zag’s bond and punctuated his words with a snap of his hips. Zagreus shivered and sobbed loudly, readily accepting of anything Than had to offer him. “I’m so happy you wanted godlings, I wanted to fill you up for a long, long time. So perfect.”

“F-fuck, oh, Thanatos!”

Cum splattered against Zag’s belly, clenching tightly around the cock hitting deep inside of him. Before Than could ask Zagreus already motioned for him to keep going, to keep reaching the most sensitive parts of him with each motion of his hips.

“Do you want more, Zag?” Thanatos ran his hand through the mess on Zag’s stomach, caressing his bump while doing so, “Do you want more children? I’d be delighted to give you more after our first is born.”

Zagreus panted against his lips, sweat dripping down his chin, “I want more godlings with you, I love you, I love you, I love you.”

Thanatos let his fingers dig into the smooth skin to steady himself. Warmth spread through his chest and smiled softly.

“Of course, Zag, I’ll give you anything you want,” Thanatos whispered, pressing a chaste kiss to Zag’s temple.

Zagreus writhed against the bed, his overstimulated hole trying to keep Than inside of him, wanting to take take take. It didn’t take long before heat swirled in Zag’s gut, his cock already going hard again against the swell of his belly.

Another forceful thrust had Zag arch his back and his eyes rolling back into his head. Than’s fat cock rubbed against his sensitive prostate, making the prince wince from pleasure.

“O-oh, Than-!” Zag’s breath hitched when he felt calloused fingers skim the hot skin of his dick. Zagreus felt Than’s lips on his, drinking in his needy sounds with fervor.

The gentle fingers on Zag’s cock wrapped themselves around his length, still slippery from the puddle of cum he produced not even five minutes ago.

Zag’s body felt like a live wire, his cock and hole were twitching madly while Thanatos pounded relentlessly into him. Each taste of Than’s tongue had Zagreus wanting to be completely consumed by his mate.

The divine heat that enveloped Than’s cock was utter bliss. It was warm, wet, and above all, Zagreus. Having his cock milked by Zag had him grip the blankets in hopes he could last longer. The prince jerked his hips against Than’s firm grip, each cant pulling him closer to the edge. Warm tears spilled from Zagreus’ eyes while he took in the delicious stimulation against his prostate. He was so so close, but it wasn’t enough.

Zagreus reached for the hand that wasn’t wrapped around his cock and pressed the soft palm to his face.

“D-Darling, bite me, please,” Zagreus pleaded, staring deep into Than’s beautiful eyes. He’d never stop getting tired of looking at them.

Thanatos grunted and leaned over to fit his teeth against Zag’s perfect skin before sinking them into the tender flesh. With an arched back and curled toes, Zagreus came over his stomach. He moaned when Thanatos continued to push into him and smear the cum along his belly.

Having sex with Zagreus while he was pregnant did something to Thanatos. He smoothed a hand over Zag’s baby bump and growled low, silently vowing to protect his lover and their unborn child. Zagreus gasped under Than, feeling the warmth of his seed fill him comfortably and the press of warm lips against his.

Thanatos leaned over and plopped on to the bed beside Zagreus, and held him close to his chest. They stayed like that for who knows how long. Just the two of them and the little one within Zagreus’ belly.

—

After an extensive amount of time, not one but two godlings emerged from Zagreus. A warmth flooded the two gods in a way they had never experienced before.

The two children shared a golden eye from Thanatos, and each had an eye from Zagreus. Their hair were different variations of a lavender purple that sat short on their heads.

Tears of joy were spilt that day, and Zagreus and Thanatos promised to care for them more than anything in the world. With the children in his lap, Zagreus twisted his neck up to kiss his beloved. It was a simple, quick kiss but it portrayed more that words could. His eyes were pink from crying but a smile painted his face nonetheless. If he ever needed more of a reason to fight, now he had it.
