Chapter Text

Diluc loved his punishments. Whatever it was he did wrong, his father would punish him accordingly. That was the reason why Diluc preferred to stir up trouble, big trouble, whenever he could. Just so his father would make a mess of his boypussy.

It had all started when Diluc found out about the wonders of starting fires everywhere on the property. Be it be inside the mansion or out in the grape fields. Crepus couldn’t stand for his son’s mischief and continuously, without rest, scolded and grounded him for it, but he couldn’t put out Diluc’s burning love for arson.

So he had thought up of another way to quell it and that was to direct it onto something else: Sex. When Diluc had tried to set one of the living room pillows on fire, he was immediately brought into his office and given a report of what had transpired by a maid, who had fortunately passed by. Crepus thanked the maid and dismissed her, watching Diluc shifting from one foot to the other. He could see that Diluc didn’t feel the least bit guilty.

“Son, since you haven’t changed your behaviour even after all the punishments I gave you, it is time to change some things,” Crepus sighed, walking over to his son.

Diluc looked up at his father, confusion written on his face. It stayed when his father put his hands on his shoulders and pushed down. Slowly he got on his knees in front of his father and waited. He wondered what he meant with changing things.

Crepus opened his pants and took out his flaccid cock. It was bigger than the average length and girth, which he was proud of, but he wondered if that size would even fit inside his son’s young boypussy. Well, if it didn’t fit, he’ll just make it fit with enough usage.

He kept his gaze on Diluc’s face, while pumping his cock to hardness. Diluc watched in rapture as his father was rubbing his penis in front of him. Compared to his own it was much bigger and much more intimidating, especially seeing it up close. The boy noticed that it became bigger and bigger the more his father touched it, and soon something started leaking out on the tip.

Crepus swiped some of the gathered precum and used it to lightly lube up his cock to ease the friction. Before he reached his climax, Crepus let go of his girth, calming his ragged breaths. His cock was now standing proudly in the air, twitching every now and then as he imagined all the punishments he was going to make and do to Diluc.

Diluc’s eyes had never left the hardened length. When his father stopped touching himself, Diluc’s trance was broken and he noticed all the saliva that had gathered in his mouth as if he was waiting to feast upon his favourite food. He swallowed, nervously shifting on his knees and noticed that the place between his legs was starting to get hotter and tingle.

Crepus noticed the way his son fidgeted on the ground, his thighs rubbing together as Diluc continued to stare at his cock. A pang of arousal shot through him as he realized that Diluc was turned on watching him jerk off and that the sight of his cock, hard and leaking, was making him drool. He felt relief knowing that his son wasn’t adverse to the punishment and it would make things easier to correct his behaviour.

A minute passed and Crepus felt enough in control of his own arousal that it was time to begin Diluc’s punishment. At first he wanted to be gentle with Diluc for his first time, but he changed his mind as he glanced at Diluc’s shorts stained with wetness. Since his son turned out to be a slut, he might as well speed up some things.

He stepped forward so Diluc was between his legs. He took his throbbing length and poked the tip at his son’s soft lips. Diluc seemed to understand what his father wanted him to do, so he opened his mouth and let the organ in.

It felt heavy on Diluc’s tongue and the flesh itself tasted like nothing, but the tip was slightly salty. Diluc felt more of the length enter his mouth and soon he felt the tip hitting the back of his throat, making him gag a bit. His father stopped moving and let his cock rest in Diluc’s warm mouth until he calmed down.

When Diluc’s coughing ceased, Crepus put his hands on his son’s fluffy red hair, patting it gently before slowly thrusting in again. Crepus threw his head back, groaning, as he felt the throat spasming down on his engorged tip. He pulled his cock fully back out of the mouth, watching as Diluc struggled with his breath.

Crepus glanced down on his cock. Since his son was untrained, he was only able to push a bit more than the tip into the hot cavern. It would take a little bit longer for him to fully sheath his cock down his son’s tight throat, but the mere thought of that happening made him harder.

Each time Diluc misbehaved and set something on fire, Crepus would extend his deep throat training. Even when he made his boy gag on his cock over and over again, his behaviour would hardly change. So he increased the intensity of the training. He started holding his son’s head in each calloused hand, making him gag, but forced him with firm grips on both sides to stay. Every time he did, he could feel the tiny mouth and throat spasming, deliciously wrapping itself around his length as he groaned.

After a month full with several lengthy sessions in a week, his beautiful son was able to take his whole cock without gagging. During that time he witnessed Diluc fall deeper and deeper into addiction of having his throat violated.

Whenever he trained him, he could always make out a wet spot in his son’s pants. The first time Crepus slammed his entire cock in, Diluc had his first squirt and that was also the first time Crepus had cum in a session. After that experience Diluc would cum every time he bottomed out in his mouth.

Diluc’s addiction was getting out of hand, Crepus mused. He would deliberately make trouble every day now, especially if Crepus could see him. So he changes the training from a punishment to a reward for behaving. It proves to be effective when Diluc doesn’t cause trouble after he started implementing the change.

As an additional reward he begins working on pussy training. When Crepus had told him that they would be doing less deep throats, Diluc had thrown a small fit. However he quickly changed his mind, after his father started fingering and eating out his young cunt, coaxing out orgasms after orgasms.

Since Diluc had a small build even as a young boy, he would be too tight to even fit his tip. So before he could fully take him, he had to loosen him up. He had bought several dildos and vibrators in different sizes. They started with the smallest size to get him used to the feeling something inside him. Diluc had squirmed when he pushed the toy inside, the silicone feeling foreign to him.

It had taken a few days for Diluc to get accustomed, but it was worth it. The next toy slid inside without as much resistance as the first one and Crepus praised him for being a good boy.

Two weeks passed and Diluc was now able to take the medium size inside him.

Chapter Text

Until now Crepus had only stretched his son with his fingers and the toys, never played or teased him with it, but with the progress Diluc made, it was time to have some fun till his son was able to take the biggest size.

Instead of the normal dildos he made his son wear vibrators at all times and kept the remote with him. Whether Diluc was with him or not, Crepus fiddled with the various settings nonetheless. He did enjoy Diluc squirming when he was in his sight, but even if not the thought of him holding back moans and hiding his shameless arousal was enough for him to get hard.

Diluc on the other hand had a bit of a hard time adjusting to the toy. The vibrator filled his pussy, rubbing against every spot with every slight movement. The tip was constantly nudging at his cervix, as if it wanted to coax it to open up and whenever he sat down it would lodge itself deeper, trying to bully its way into his womb.

The worst was the vibrations at random times. The first time it happened was during dinner with his father. He had his fork midair, mouth open, when the sudden vibrations started rattling his insides. He had let out an embarrassingly lewd moan, his grip on the silver utensil tightened when he realized that it would stop any time soon.

Diluc turned to his father, who was calmly eating his dinner, not acknowledging Diluc’s obvious distress. Squirming, Diluc rubbed his thighs together, trying to hold back the building arousal, but instead of doing that, it had the opposite effect.

Diluc could feel his body heating up as the vibrations increased in intensity. The way the vibrator stirred up his insides felt so good, especially against his cervix. He had already loved it when his father played with it, fucking either his fingers or a dildo against it, but a vibrator just felt way better. This felt more satisfying, pulsing against every nook and cranny of his pussy.

With that Diluc lets out a high-pitched whine as he cums. The vibrations don’t stop as he comes down from his climax. He drops his fork to touch the protrusion on his belly. The redhead could feel the toy under his small hands and moans. Soon the toys’ ministrations overstimulate his insides, making him whimper and squirm.

Diluc takes a glance at his father, who still doesn’t look at him. Instead Diluc watches as his father takes out a small remote, fiddles with it for a few seconds before the toy inside him pulsates more violently, jostling his already over sensitive flesh and forcing another orgasm out of him. Diluc sobs as his body is wrecked with painful pleasure over and over again with each pulse from the toy.

Just as he felt like he was about to pass out, the toy stills. Diluc lets out a sob as his body slumps back into the chair, little aftershocks still coursing through every fiber of his muscles. While he was breathing heavily, mind clouded and muddled, he barely felt his father cradle his lithe body. Diluc could hear soft, baritone whispers over his head, the faint warmth of lips atop his head. Then strong, muscular arms lifting his tiny body and the next thing he knew was nothingness.

The days continued like that, with Diluc being tortured with toe-curling pleasure until he was a panting and writhing mess. When his father was busy with the winery and could not even spare a single thought for him, he was left with an incessant throb between his legs, but after so much training he was unable to cum by himself. He always needed his father to help him. And after long, painful hours rubbing his aching pussy against pillows, or when he was especially desperate against the corner of his study desk, his father finds him crying miserably with his shorts down, rutting against pillows or desk corners like an animal in heat.

At last Diluc was able to comfortably take the biggest toys and that marked the time when Crepus would finally be able to take his son’s virginity. His plans however were foiled by work, so he had to make due with a quick deepthroat until he came back.

Before he left, he bound his son to his bed and gagged him. His hands were restrained above his head, locked to the headboard. Each of his legs were clasped together by a rope, a spread bar keeping the bound limbs open, so Crepus had a free view on Diluc’s leaking pussy, speared on the biggest vibrator, just about the same size as his own. To heighten Diluc’s pleasure, he tied a black cloth over his eyes and plugged his ears.

Crepus admired his son’s beautiful body, stroking the naked skin just above his little clit. He could feel little tremors under his fingers with each touch, but work came first. So he turned the vibrator on at max settings, ignoring the surprised gasp and the following muffled cries as he closed the door behind him.

It had been a few agonizing hours of work before Crepus was allowed to leave the tavern. As he exited the building he could see the dark clouds above the night sky, just dimly lit by the moonlight. He quickly calls for a carriage before the storm could fully settle in, but as the archons would have it, the storm was already raging on before he made it back to the winery.

A sudden stop of the carriage draws his attention. Crepus quietly listens to the muddle voices outside of the carriage. There was a knock on the side of the carriage and the door opened to reveal the driver dripping wet from the pouring rain.

The driver tells him of the situation. A child, barely ten years old, was sitting at the side of the road, huddled into a ball, trying to shield itself from the harsh weather with its tiny hands. The driver had taken notice and called for the child to come closer. The child’s father had gone to get some grape juice and still after hours of obediently waiting, he had not come back for him.

Crepus took pity and ordered the driver to bring the child in. The moment the child stepped into the carriage, Crepus took notice of his rather foreign traits. Eyes with star pupils and brown skin. The winery’s master found them odd, but the small frame of the child was shaking so much, his previous thoughts were quickly forgotten.

He shed off his coat and wrapped it tightly around the shivering form. The shaking didn’t stop, but at least his condition wouldn’t worsen any more than it already was. So he ordered the driver to hurry back to the winery, lest the child will end up sick.

Back home Crepus takes the child straight to the bathroom to start a warm bath. He also orders the lingering Adelinde to get some fresh clothes and she hurries to follow the order. All the while the child stays silent, only answering questions directed at him with a nod or shake of head. The only word he had spoken was his name: Kaeya.

After Crepus had made sure of Kaeya’s well-being, he put him to bed in one of the guest rooms that was a bit closer to his bedroom in case Kaeya needed anything. He stayed seated on the bed until Kaeya’s breaths evened out, signaling that he had fallen asleep.

Crepus quietly leaves the room and walks back to the bedroom. The moment he opens the door, he is greeted by a sight he had been craving hours ago.

Diluc was still in the same position as he had left him. Other than that his pussy was thoroughly wrecked, a nice shade of red from the continuous vibrations, leaking wet, soaking the sheets beneath. His body was sweaty and his face a mess of drool and tears.

As Crepus stepped closer, he saw the body twitch, but otherwise motionless. It seemed that his son had passed out during the time he was away. He stopped at the bedside, gazing at his beautiful son. His erection was already painfully straining in his pants and he wished nothing more than to ravage him, but he had left Diluc for such a long time. If he were to take him right now, it would do more harm than good and he doesn’t want his son hurt.

He ignored his arousal, untying the ropes, removed the ear plugs, gag and the blindfold. Crepus checked up on Diluc’s condition, but found nothing off except for the expected strains in the muscles from staying in the same position for too long and the numerous orgasms. He cleaned Diluc’s body with a clean towel, removed the dirtied sheets and replaced them with new ones, careful not to wake the slumbering beauty.

After laying his son on the clean sheets, he slowly massaged away the soreness in the tense muscles. He started from the neck and worked his way down to the feet. Just as he was done, the body stiffens before stirring awake.

Diluc’s eyes blearily open, gaze unfocused and eyelids heavy with tiredness. He makes out a blurry shape of red in his vision and hazily recognizes his father hovering over him. The long, torturous hours of stimulation are still thrumming in his limbs and he whines as he remembers them. His father had taken so long to come back and all the orgasms had left him boneless and tired, but due to the vibrator inside his cunt, the sensation never gave him any time to rest. In the end he passed out from exhaustion, but even in his sleep he could still feel the tingling sensation in his lower parts.

Diluc could feel the emptiness inside him now. It was weird and he squirmed, trying to elevate that feeling by pushing his fingers inside. His thin fingers did nothing to help however and he gave a broken sob, throat hoarse from the screaming he had done through the gag. He tries to finger himself faster, tries to push farther inside his fleshy cavern, but the hollow feeling doesn't dissipate. No, it was the opposite. The feeling surged in intensity, fanning the flames in his belly. His little cock fills once more, standing up, seeking the attention of his father.

Crepus swallows, watching as Diluc desperately tries to fill his hole. His cock twitches in interest and he could feel his lust winning over his rationality. Diluc looked so debauched, so ready for him to fill him up with his cock. The nail on the coffin was Diluc locking gazes with him, his eyes cleared from sleep and the pained expression.

“Father-”, Diluc calls for him, his voice shaking. ”Help! I feel so empty!”

“Diluc, you-” Crepus doesn’t finish, instead he pounces on his son, quickly unzipping his pants and freeing his strained erection. Cold air hits the hot flesh and he hisses at the feeling, but pushes it aside to remove the small hand from the leaking pussy.

Between his son’s legs, he could see his cunt twitching in excitement and gaping, no doubt from the numerous sessions stretching the flesh at all times. Crepus groans, lifting Diluc’s hips in the air and pushing the knees as far as he could, folding Diluc in half.

Crepus lines up his cock at the opening, smearing the juices from the wet fold on his cock head. He pushes in, parting the flesh and he gasps. It was tight, hot and wet. It was an amazing feeling. The way the walls were clamping down on him and intensified the heat was delicious. He had been waiting for weeks and in this very moment he could only hyper focus on this sensation.

He gave a tentative thrust, testing out the waters how his son would fare. His son keened in pleasure, the head of the cock bumping into his cervix, sending a spark of pleasure through him. His body was so sensitive, all the edging and training sessions made him so receptive to pleasure. Diluc could feel the ridges and veins of the hot rod moving inside him, rubbing against all the spots that made him feel good.

Diluc cries out, another but stronger thrust bumps into his cervix, making his toes curl. His father begins a steady rhythm, not too hard but strong enough to let him feel it through his pleasure-addled mind.

Crepus groans, eyebrows scrunched together as he slides in and out of his son. With every well-aimed thrust into the spongy entrance to the womb, the wet walls around him would squeeze down on him. An especially strong squeeze causes him to buck harshly into the cunt, which in return makes Diluc yelp.

Crepus had stopped moving, gathering his bearings before he lost all self control and hurt his son in the process, but of course the little minx was an impatient one. The moment he had stopped, he could feel the tiny body under him squirming and whining, begging for him to move. Drops of tears fell from his eyes as he was denied the pleasure given to him and the heat coiling in his belly slowly staved off.

“Father! Move please! I can’t-” Diluc begs, eyes filled with more tears as he realizes his father still wouldn’t move. Just as he was about to continue begging, his father moved, but not the way he wanted. He felt his father moving off of him, the warm body leaving his own heated one and the cock inside his cunt sliding out, leaving him empty.

However before he could protest, the cock slams back in, crushing his womb under its force. Diluc chokes out a strangled scream, gasping as the cock doesn’t give him any time to process his thoughts. It pistons in and out, punching out moans and wet gasps out of him and he loves it. He loves it so much! It was so much better than the cold and rigid feeling of vibrators and plugs inside him.

A harsh thrust into his g-spot sent Diluc over the edge, uncoiling the burning heat in his belly. He cums around his father’s cock, eyes rolled back and drool dripping from his mouth. The cock inside him doesn’t let up, fucking through his orgasm. Diluc tries to escape the overstimulation, but all he could do in his state was to weakly pull at his fathers arm still holding onto his legs.

Crepus could feel the moment Diluc reached his climax. The heat around him was spasming around him, as if it was trying to coax the cum out of him and it worked. He growls, feeling something inside him snap and he pushes his body weight into his son, effectively burying himself as deep as he could inside the greedy pussy, against his son’s womb, and cums.

As soon as his cum fills his son, he feels wetness hitting his pelvis and thighs. He looks down to see Diluc’s cunt fluttering, small squirts spurting out of his urethra. His mind reels as he hears his son weakly whining, the same sound he always does, when he is lost in pleasure deep-throating him.

Crepus swallows the lump in his throat that had formed. He had only intended to take Diluc once, seeing as both his son and him were so far into their lust-addled minds, but now? There was no way that he was going to let this night end with only one round. Not with his beautiful son beneath him, so responsive to every touch he gives him, being such a good boy for him.

And so Crepus spends the night with his son, fucking him, filling him and defiling the last shred of the innocence his son had with his own dirty hands and what else could he do but love every second of it?

Chapter Text

Kaeya had been peeping on them, watching the father, the man who had kindly taken him in, fuck his own son, breeding the wet pussy over and over again, not stopping until both of them were too exhausted to move. They settled down in the bed with Crepus spooning his son, cock still nestled inside the little cunt to be warmed and went to sleep.

Kaeya gulped, tearing his eyes from the scene and he glanced down on himself. He spotted a small tent in his pants, insistently throbbing, especially whenever his mind flashed back, that big cock slamming inside that tiny hole. His cock twitches at the memory and he has to suppress any noises, fearing he might be heard.

Kaeya wobbled back, careful not to jostle the throbbing erection between his legs, which would send a hot spark down his spine whenever there was a slight touch.

Back in the guest room, he slipped into the soft bed, pulling the duvet up to his chin. He closes his eyes and tries to go back to sleep, but vivid images of a tiny body held down, legs spread wide open for a man much bigger to spear him open-

Kaeya gasps, eyes flying open and unconsciously bucking up his hips as if to thrust it into something. Kaeya lets out a shaky breath. The thought of having a peaceful sleep seemed so far to him that night.

The next day Kaeya was introduced to Master Crepus’ son, Diluc. From up close he was even more beautiful. Long crimson hair that looked soft to the touch, porcelain white skin like that of a brand new doll and the round curves of the young boy made him even more appealing than he already was.

He had feared that Diluc would reject him, denying him entry to the household as he hailed from foreign origins, but to his surprise Diluc welcomed him like he had found his long lost brother.

They spend the following years together, sticking to each other like glue, playing in the vineyards, exploring the nearby area, going swimming in the river…
And what Kaeya had found the hardest to do with Diluc was sleeping together in the same bed.

Kaeya had found out that Diluc was a notorious deep sleeper. Nothing he did had woken him up and the red head would peacefully sleep the night away as if nothing had happened, not even with Kaeya desperately humping the back side of his brother. With every grind against Diluc’s bottom, the lithe body jostled, but remained limp and pliant and that made Kaeya even more aroused.

Kaeya shamelessly moaned into Diluc’s ear, knowing that his brother would remain asleep. He had been using Diluc’s sleeping body as masturbation material since the first day they slept together. At first he felt guilty, but the sheer lust he felt for Diluc was unimaginable that he threw all of his morals away after the first few nights.

Kaeya’s breath stuttered as he came, staining both Diluc’s shorts and his own. He lets out a breath, slowly coming down from his orgasm. Kaeya had ejaculated, but there was a part of him that felt unsatisfied, deeply so and he knew why.

His cock twitched in interest, coming alive again. Kaeya slid off his shorts, freeing his leaking cock and rubbed it against Diluc’s wet folds. He moaned at the feeling, Diluc’s own juice and Crepus’ seed coated the head of his cock as he slid it up and down. He hadn’t tried fucking Diluc yet, too cowardly in fear of being found out, but time passed and not once had Diluc mentioned anything weird while he slept.

Soon Kaeya’s own morales deteriorated and he began craving more and more. He craved the same feeling that Master Crepus felt whenever he fucked his son and with Diluc always so close to him, whether it was during the day or night, it was hard not to lose control over his own desires.

The moment Kaeya pushed the head of his cock past the hot entrance, the thin line holding his self control snapped and he thrust his hips up, sheathing his cock inside in one go. Bliss is what Kaeya felt. The way Diluc squeezed around him, so warm, so wet and so tight. There was no way that anyone could go back after they had a taste of that body.

Kaeya rolled Diluc onto his stomach and started pounding inside the body. He groaned as wet squelching sounds echoed through the room. Kaeya glanced down where Diluc and he were connected. He watched Master Crepus’ cum leaking out of the hole, staining both his cock and the sheets below him with each thrust.

With an especially hard snap of his hips, he could feel his cock knocking against something. Curious, he kept slamming himself into that place and suddenly the body under him tensed, his ass rutting back onto his cock and back arched as wetness coated Kaeya’s thighs.

Stunned, Kaeya realized that Diluc had squirted. A hot spark ran through his spine, fanning the flames in him. He grabbed Diluc by his hips and pushed his entire weight into his thrusts, his mind filled with only one goal: To breed his dearest brother.

Every thrust felt more amazing than the last. The heat inside him swirling and heating his body. Sweat gathered on his skin, the harsh movements sapped at his energy, but he pushed through, trying his best to get Diluc to cum again and reaching his own climax.

Another hard slam inside the hot cavern has Diluc spasm around his brother’s hot cock, small droplets of fluid trickled down the milky white thighs. The sight and knowledge that Kaeya had managed to make him cum again, pushes him over the edge. He grinds his cock as deep and far as possible inside his brother’s pussy, shoving the head of his cock against the entrance of Diluc’s womb, the place where his child would grow, Kaeya’s mind whispers, and he cums.

Kaeya shuddered, feeling his semen filling up his brother’s belly. He snakes one of his hands around Diluc’s front and traces the bulging belly. He could feel the outline of his cock, but was disappointed to find that the belly wasn’t round enough. That was, however, easily fixable. All he had to do was breed his brother some more, maybe even plugging him up to keep his seed inside.

The next day Kaeya was called into Master Crepus’ office, the maid passing on the message also adding that it was urgent. While making his way to the office, he feared that Master Crepus had found out about his nightly activity with his son. Not to mention everything he did was done while Diluc was deep asleep.

Before he realized it, he stood outside the double doors and he gulped. He knocked twice and the voice of Master Crepus immediately called him inside. Kaeya opened the door and stepped inside, only to freeze by what he saw.

Diluc’s body was lying down on the desk, hands bound together at the front and each leg bound to the thighs with the two inviting holes turned towards the door. From Kaeya’s spot he could clearly see the glistening pussy of his brother and judging from the light pink colour it seemed that Master Crepus had not penetrated him just yet. Instead Master Crepus’ cock was shoved deep inside Diluc’s throat, fucking it in short pistons. Kaeya could faintly hear Diluc gagging, but not once did he resist or pull away.

Master Crepus turned his attention to him and smiled at him warmly.

“Kaeya, it’s good to see you here early. Diluc and I already started,” Crepus greets him nonchalantly, grinding his cock deeper into the warm cavern, which elicited a gargled moan from Diluc.

“Master Crepus, you-”

“How long has it been since you’ve arrived here, Kaeya?” Crepus cuts him off. Kaeya, unsure of what to do, closed the door behind, having almost forgotten that it was still open, before walking further inside, standing in front of the two other people in the room.

“Almost three years, Master Crepus”

Crepus hums, bucks his hip one more time and groans. Kaeya saw the way the huge cock twitched, the bulge in Diluc’s throat so visible lodged inside that tight throat. Crepus made sure that all of his seeds were completely emptied straight inside his son’s belly and then slowly slid his cock out so his son was able to feel the drag heavy on his tongue. His springs out from its warm confines, still half hard even though he had just cummed.

“Three years, is it?” Crepus chuckles, “Diluc is already at that age, where his puberty should hit. So it’s only a matter of time for him to get pregnant.”

Kaeya froze. Diluc and pregnant? Sure, he had imagined that when he fucked him last night, but actually pregnant, his belly big, swollen and round? Not to mention if it were Master Crepus’ child or his. That thought made his cock hard.
Master Crepus, ever the observant man, noticed his growing arousal.

“As you can already guess, I plan to knock him up with either my child or yours. After all, we both love Diluc and it’s already too late for us to turn back and live a normal life as a normal family. We might as well embrace our desires and indulge in them.” Crepus slides his hand down the small body, stopping at the sopping wet cunt and gives it a spank. Diluc cries out at the sudden flare of pain, but Kaeya knew that the pain just fueled his brother’s thirst to be absolutely filled.

“Since we need to make sure that our seed takes inside Diluc, we’ll switch breeding him when the other is busy and if both of us are busy, we’ll have him plugged up.” Crepus takes out a massive dildo from his desk drawer. It was a bit bigger than his own cock, just about the right size to not let any of their semen escape from Diluc’s womb.

Crepus set the dildo down and took a place in his office chair.

“Kaeya, make sure you cum deep inside that pussy” Crepus smiles, one of his hands languidly stroking his cock up and down.

Kaeya swallows the spit in his mouth, his cock had gotten painfully hard while he had listened to his foster father talk. He still couldn’t believe that Master Crepus was giving him explicit permission to breed his brother and who was he to oppose such a wonderful task?

Kaeya moaned, his cock swallowed by the heat of Diluc’s pussy as he slammed in and out of it. Diluc squealed each time his cock knocked against his cervix, delirious in the heat of the moment, but very aware that both his father and brother were going to put children into him. After his father had found Kaeya using his sleeping body like a sex doll, he had told Diluc what he had planned for him and Kaeya.

He knew early on what his father had been doing to him and what possible consequence would come out of it from his sex education lessons. In the back of Diluc’s lust-filled mind he knew that his father committed sinful acts, but every time that big, hard cock would stretch his pussy and fill him with that warmth, he couldn’t help but give in to that sensation. The thought of carrying their children sent him over the edge and he came, milking Kaeya’s cock, desperate to be full of his seeds.

Kaeya flinches as he suddenly feels Diluc clamp down on him. One look at Diluc’s teary and blissed out expression makes him cum, pumping his semen inside as far as he could, just as Master Crepus instructed him to do.

While both children were catching their breath, Crepus stood up, pulling Diluc away from a tired Kaeya, who let him and before the seed could leak out, rammed his hard cock inside his son. Diluc shrieked, his pussy stretched so wide to accommodate his father’s girth. The stretch wasn’t as painful since Kaeya had been fucking him seconds before, but his father was still sizable and he was feeling the strain.

“Not yet, Diluc. You still have to take my seed.” Without waiting for an answer or for Diluc to adjust to his size, he pulled out until the head of his cock remained inside and slammed back in, instantly plunging against the entrance to his womb, drawing a gasp out of Diluc. His father kept up a fast pace, giving him no time to rest as he was used like a ragdoll for his father’s personal use. It was a bad thing, Diluc thought, but Archons did he love it.

“Mh? You just got tighter. What were you thinking about, Diluc?” His father cooed, his pace brutal and unrelenting in comparison.

Diluc opens his mouth to answer, but is cut off when his father easily lifts him up from the desk. He flails mid air, scared that he might fall with no way for a grip with his tied up hands and legs. His father lifts him further up until the head of his cock remains inside. Diluc’s eyes widen as he realizes what his father intended to do. He squirms, shaking his head, tears fall from his eyes, but all to no avail as his father drops him back on his cock.

His entire weight drops, the slide was fast and the girth lodged itself deeper than before with the position and the force. It felt like the cock was crushing his womb. Diluc’s eyes roll back into his head as several intense sensations explode inside him. His father was merciless. He lifted him up and dropped him numerous more times and each time he did, Diluc could feel his insides being rearranged, making more room for that massive cock.

Crepus drops him one last time and additionally thrusts up, meeting the body halfway. Diluc screamed as the cock rammed inside. He barely noticed the heat flooding his pussy as he reached his own climax, squirting and wetting his father’s and his own thighs.
