Trouble In Simulated Universe

Summary:

One day, Dan Heng wants to join Caelus entering the Simulated Universe out of worry. Unfortunately, Aha decides to become a menace at the same day

I wrote this for a Secret Santa Event in a discord server

Notes:

It's my first time writing NSFW, so please don't expect much but enjoy ^^
I had to open several other nsfw ffns and google translate for reference. Writing nsfw is harder than I thought

(See the end of the work for more notes.)

Work Text:

“To make it simple, there were some errors in the Simulated Universe caused by Aha, again” the holographic Herta sighs annoyingly while massaging her temple, already fed up with the simulation version of the Aeon of Elation’s pranks. “Nothing serious, it’ll just make the path you choose and its resonance work a bit differently, and by the looks of it you get affected by the Abundance path, while your friend gets affected by the Propagation path.”

 

“I- I see! Then could you please get us out of here now, madam Herta?” Caelus asks impatiently while slapping the pair of hands snuck inside his shirt for the umpteenth time. “Not now…!” he gives the raven haired man hugging him from behind a warning.

 

“Sorry…” Dan Heng, who’s in his Imbibitor Lunae form, whispers with his head still buried deep to Caelus’s neck. His body is bursting with heat as If he’s burning inside that he starts soaking in sweat. As of now, inhaling the boy’s scent calms some of his instinct, enough for him not to pounce at Caelus while Herta’s still talking with them.

 

Herta, ignoring the scene in front of her, continues her explanation, “I have been trying to force you two out, but it seems like the errors make me unable to. You two can either beat the final stage to be automatically sent out, or just wait until the problems are fixed. Anyway, I need to go get Screwllum to fix this. Then, I’ll cut the communication.”

 

Not even a second after Herta’s hologram disappears, Caelus’s vision suddenly spins around and he finds himself being pinned to the ground with Dan Heng hovering above him. His eyes are glowing in  green and face red in lust. Breathing heavily, he leans down in attempt to take those plush lips in a kiss.

 

“Wait! Hold a sec! Can we at least move to a more closed place first!!???” Caelus yells in panic while pushing the Vidyadhara’s face away with all of his might.

 

“Caelus…” Dan Heng frowns, obviously displeased with the other’s rejection. Although, he quickly reminds the feral part of his mind that Caelus only asked for a change of place. He grips his hands tightly trying to suppress his instinct just for a short while. Even as his mind is clouded by the Propagation path, the sane part of him will be extremely disappointed at himself If he makes Caelus feel uncomfortable. Then, he takes a deep breath and uses every ounce of his might to keep his sanity intact.

 

“Alright, let’s go.” He forces those words out of his throat as he immediately carries Caelus' body into his arms and sprints. Caelus is bewildered as he seriously thought Dan Heng would take him right there in the open, and yet he manages to fight off the Propagation influence for him.

 

For him… Caelus can’t help but squeals happily though he himself doesn’t understand why he did just that.

 

An abandoned building in the distance there should be sufficient and thankfully when they arrived the door isn't locked or else, he might have blown a hole to the building and it won’t be a secluded place anymore like what his lover wants. Dan Heng places Caelus to a nearby bed and climbs on top of him. “This should be ok, right?” He asks, face coming closer till both of their noses’ touch.

 

Caelus nods while chuckling. It must be hard for him to endure. “Yeah… thank you.” Then he puts both of his hands around Dan Heng’s neck and gives him a peck on his lips. “Then breed me.

 

Caelus pauses. What the fuck did he just say just now? That isn’t him he swears! The grey haired looks up in panic to see a sight even scarier. The sheer desire and possessiveness are reflected clearly on those lit up green eyes of his Vidyadhara lover. Face darkened from shadow as he is facing away from the light, the Dan Heng above him is just like a predator cornering its prey, and Caelus, the prey, has no way out of his grasp.

 

Dan Heng crashes his lips against Caelus’ that he sinks to the bed a bit. “I’m sorry, though it’s your fault too.” He whispers before crashing his lips once again now with more force, earning him a gasp of surprise from Caelus which Dan Heng takes advantage of and pushes inside his forked tongue.

 

His long serpentine tongue explores every corner of Caelus' mouth, tasting and enjoying the warm wet cavern before intertwining both of their tongues together. Muffled gasp and moan come out from Caelus’ throat which makes Dan Heng get even more confident in his movement that he starts to go far and further back to the back of his mouth till his tongue intrudes the other’s throat. Caelus feels as If he is floating in cloud nine with the serpentine tongue reaching out as far as it can and licks every part of his throat as If marking it as his.

 

Dan Heng’s hands then travel to the boy’s chest, flicking the erect nipples before giving them a hard pinch. A loud muffled scream of both surprise and pleasure comes from Caelus. It feels painful but at the same time feels so good that he puffs out his chest more, encouraging Dan Heng to continue. The raven obliges by continuing to pinch and twist those erected nipples more. Out of nowhere, his fingers feel wet after he pinches the nipples quite hard. Afraid of accidentally hurting his lover, Dan Heng abruptly breaks the kiss and looks down in panic. Caelus whines in annoyance though noticing Dan Heng’s wide eyes looking down, he follows where he gazes at. There are somehow two damp spots on his shirt around the area of his… nipples?

 

“Wh-what is that?” Caelus can only confusedly look at the damp spots. His still trembling body from the pleasures unfortunately makes his movement rather sluggish.

 

Dan Heng, still looking in disbelief, lifts up the white shirt to find white liquid coming out of Caelus’ nipples. Caelus’ mouth agape while Dan Heng curiously takes the not so mysterious white liquid to his finger and licks it.

 

“It’s milk…” Dan Heng states in surprise. Seeing Caelus’ shock expression, Dan Heng continues, “Well… Madam Herta said you are affected by the Abundance path… I suppose this is the effect.”

 

“Huh? What’s even Abundance about… this?” Caelus confusedly asks as he tries to take a better look on his chest. Then he notices Dan Heng who still has his eyes locked into his chest. “Dan Heng? Are you there- Aa~hh! Hey stop it!”

 

Dan Heng pinches one of the nipples which earns him a beautiful moan coming from Caelus and another drop of milk leaking from it. The sweet smell coming from the milk and the beautiful moan accompany it. Oh, Caelus is leaking milk, like a pregnant mother, like his body is ready to be bred, like he is ready… to be propagated.

 

Something inside Dan Heng snaps, and the next thing he knows he already launches forward, taking the left nipple inside his mouth while rubbing the right one with his hand. Translucent tail materializes behind him, immediately taking hostage Caelus' hands before they can do anything, pinning them above his head. Caelus’ mouth lolls with his tongue out as he screams in pleasure from the sudden stimulations. The Vidyadhara starts sucking hard the nipple on his mouth while also lightly teasing them with a lick from his tongue.

 

“Dan- aahh..!! nhhghh-” Caelus moans, any attempt of him to talk is turned into incoherent mumbling with moans only. Hands gripping tightly on the tail binding him with his legs circle on Dan Heng’s back.

 

Gush of milk comes flowing down his throat and Dan Heng greedily drinks all of them. So sweet and delectable unlike any other drink he tasted before that he is disappointed, he won’t be able to taste it anymore after they get out of the Simulated Universe. If Caelus is able to produce milk in the real world too, Dan Heng bet he’ll taste even sweeter than now, more delicious and addicting… like a drug. More, he wants to taste more of it.

 

“My precious... mine. Only mine.” Dan Heng growls possessively.

 

Oh, all of this feels too good for Caelus. He keeps moaning, screaming at Dan Heng’s name like a mantra. His stomach is burning with heat along with his cock standing up hard releasing precum and… huh? For a moment Caelus feels an alien feeling at his crotch. Like there is something else twitching and wet between his cock and his ass. “Ngghh!?” Those thoughts are soon cut short with a hand suddenly gropping his crotch.

 

“Heh… you’re already this wet just from your nipples?” the Vidyadhara teases as he grazes his sharp teeth along the nipple making the grey haired gasp. He pulls off Caelus’ trousers easily and starts pumping his cock, using the sharp tip of his fingers to twist the top.

 

“Oohh… ahh.. Danh.. ngghh Hhenn… mnhhgghh…!” Caelus mewls in response. The sharp nails prodding into the tip of his cock feel painfully good and how skilful his hand pumping it. Dan Heng’s mouth also goes back sucking now on his other nipple and it’s too much… too much for him to handle.

 

“Aaahhh!!!” Caelus moans loudly as he comes hard. Cock spurting out thick white cum along with his nipples gushing out liters of milk to Dan Heng’s mouth. His body then goes limp, tired from his first release as he pants. The tail bounding his hands finally lets go of them, instead it helps Dan Heng spread his still wobbly legs and place them in his shoulders, making Caelus whine as he’s still tired from the release.

 

“Oh Caelus…” Dan Heng suddenly murmurs with lust while gazing at his lower abdomen. “You just love to keep surprising me, aren’t you?”

 

“Wha...? What do you me-eaannnghh??!? Aaghh?!! Wha- what?!” Caelus screams in both confusion and pleasure. He quickly looks down to see Dan Heng has inserted a finger to… where? He doesn’t feel anything inside his ass, but he feels a finger moving around inside him, deeper and deeper. It feels weird, a bit hurt but strangely good, but what is it? The grey haired starts grasping for something to grip which Dan Heng happily gives his tail to the boy which he instantly hug tightly.  “Dan Heng- Dan Heng..! It feels weird! Ooh- Wha- is??” Drools come out his mouth from how good it feels having Dan Heng playing with his unknown inside.

 

“It’s another effect from the Abundance path.” Dan Heng softly says as he kisses the thick thigh of his lover to reassure him. “You grow a vagina, love. And it looks so lovely and delicate.” A delicious squelching sound can be heard as another finger is thrust inside, stretching the hole to open up more. Caelus whimpers as tears start streaming down from his eyes, the new found pleasure feels even better than before even without his cock nor nipples are played too, but it’s… too much for him.

 

“It’s fine.. It’s fine… relax your muscles, Cae. Breath slowly…” Dan Heng stops his movement and coos the boy worriedly when his breath becomes more erratic, peppering his thighs with light kisses. He uses the fluff at the end of his tail to wipe the grey haired tears. Caelus’s breathing slowly becomes relaxed again and Dan Heng can feel how the muscles inside start to loosen up. “Yes, just like that. Now let’s continue, yeah? Yeah?”

 

Caelus, still panting, looks up to see his lover's face, cheeks red in lust but his green eyes also sparkle in expectation for his approval to continue. Even the dragon tail in his arms is wagging slightly which looks more apparent when he looks at the tip of his tail that he isn’t holding waving back and forth. Cute, is Caelus’ first thought when he sees him that he has a thought to tease him. However, a burst of heat suddenly gathers inside his stomach like a pool of lava that he hitches in displeasure. The ticklish feeling he feels from Dan Heng’s fingers still inside of his pussy just makes it worse and he grabs Dan Heng’s arms, trying to move them to quench his sudden thirst.

 

“Yes! Yes! Please move already- Ooghhh~!” He moans in pleasure, mouth forms like the letter O with his tongue rolls out to the side.

 

“Ah, I guess I was worried for nothing, you greedy boy.” Dan Heng starts thrusting inside the boy’s pussy again harder, hunger consumes him once more that he drools at the sight of the delicious pussy in front him. To stuff him full of his cement. To propagate.

 

This sudden thirst, this sudden urge to be filled… is this caused by the Abundance path affecting him? Caelus doesn’t know nor care anymore. He just needs Dan Heng to stuff him full with his cocks right now. To bring a new life.

 

“Dan Heng! Dan Heng! Put them inside me! Please! Please!” Begging he does as he put his arms to spread both his pussy and ass. Who cares If he didn’t prep enough, he needs him now inside.

 

Dan Heng, though tempted, with him quickly freeing both of his already hard cocks from his pants, stops when he lines them in front of Caelus holes. The remaining sane part of him screams bloody murder that he hasn’t even prepared the other hole. You want him to feel good not pain, the sane part screams that at him. “Caelus… wait, just a moment.” Dan Heng bit his lips to swallow another wave of heat in his cocks. Just a quick prep and he can put them inside, he has to repeat those thoughts in his head as he quickly shoves two fingers inside Caelus’ ass, doing a sloppy job at scissoring it. Caelus whines impatiently though he can’t do anything as the translucent tail has, unconsciously by Dan Heng, wraps itself around Caelus’ body, locking him in place.

 

For some reason, Caelus’ ass is producing an abundant amount of slicks the same as his pussy, making Dan Heng’s job easier. Another effect from the Abundance path he assumes. It takes only a short time for it to be loose enough and Dan Heng quickly lines up both of his cocks and shove both of them inside at the same time. Caelus’ mouth agape, attempting to scream but no sound comes out. It feels so good, his insides clenching the hard and heavy cocks almost like trying to trap them inside forever.

 

“Cae, you feel so good…” Dan Heng praises him as he caresses the bulge on his lover's stomach caused by his cocks inside. It isn’t the first time he has seen how his lover's stomach will bulge beautifully every time they want Dan Heng to put both inside, but this time the bulge was also caused by one of his cocks inside Caelus’ lovely pussy which just made him get even more excited. Caelus should have a womb too, right? Can he fuck him there? Can his cock reach inside his womb? Excited with his new thought, Dan Heng begins to move, bringing his cocks out till it’s just their tip then slamming them inside with force, earning a loud moan from Caelus that his back curves slightly. “Look at you, so beautiful and perfect for me.”

 

Caelus can only moan and scream happily, unable to make any incoherent sentence to reply to his lover. The thrust he feels just became more and more erratic each time, hitting him deeply to his prostate in his ass and another spongy thing in his pussy. His own cock, still hard and begging for release, is left bobbing forgotten as Dan Heng’s tail is still locking him.

 

Dan Heng thrusts and thrusts so hard, being drowned in his own lust. The moan and scream he hears from Caelus feels like a song to his ears which he indulges in. Pretty, beautiful, the perfect lover for him, how many times did he already say that to him? But all of those are the truth though as Caelus receives each thrust with such a delightful face, wanting more and more. Even as he dives his head to his nipple, sucking the milk which has flowed like a waterfall once again, Caelus only receives it gladly with his eyes locked in to him only. Only him.

 

Bite.

 

He finally took his first bite on Caelus’ neck, making the boy scream in pleasure. Normally, his lover’s neck will look like it’s mauled by the time his dicks are already thrust inside, but he guesses it’s because of those new things his lover possesses now that he forgot to do just that. Then he just simply needs to bite more, and more, and more. Marks of possession, symbol of his possessiveness to him. Those marks will disappear completely after the simulation ends, but maybe just maybe, If he places many of them, one of them might just appear in real life, or at least Caelus must be still feeling those bites he gave him here. “Mine. Mine. Mine...” he keeps murmuring those words.

 

As he thrust hard and deeply pushing his cocks inside, he feels the cock inside the pussy finally penetrate inside the abused spongy walls he feels earlier and the next thing he hears is Caelus’ scream. Does he do it? Does he finally breach the forbidden place? Caelus’ womb? Oh... oh… how wonderful it feels that he almost regrets putting his other cock inside the ass instead. A low excited growl comes out of his throat as he thrusts even faster, fucking Caelus’ womb in ecstasy. He’ll make him pregnant with his kids, then after that he’ll fuck him and get him pregnant again. He takes another bite on his neck in glee while his hands now squeezing the abused chest like a breast, trying to squeeze every single drop of milk out.

 

Everything starts to grow fuzzy around Caelus’ vision, the only thing he can feel beside the air getting hotter are the double thrusts he feels deep inside of his womb and ass. Oh, how he wishes he can keep his womb even after the simulation ends. How good will their sex be If he still has his womb? Getting penetrated in both holes or even wilder he can ask Dan Heng to use both of his cocks to penetrate his pussy. Then he’ll get pregnant with Dan Heng’s kids. How wonderful will it be, he thinks as he let out another moan of Dan Heng’s name.

 

Claim him

 

“Caelus…!”

 

Submit yourself

 

“Dan heng~!”

 

Mate him

 

“Mate… my mate...”

 

Let yourself be bred

 

“Yess! Yess! Breed me!”

 

TO PROPAGATE

 

“I’ll fuck you until you’re pregnant!”

 

TO BRING AN ABUNDANT OF LIFE

 

“Yes! Make me pregnant with your child!”

 

Caelus screams as he cum hard on his pussy and his cock untouched. His chest also shooting out another gush of milk as he cum. Dan Heng thrusts a few more times and with the new pulsating and tightness feeling from Caelus’ overstimulated holes, he pushes both of his cocks deep inside as he finally cum and releases gallons of cum inside his lover’s ass and most importantly his womb. He let out a loud growl and bite once again at Caelus’ already bruised neck. Caelus only whines tiredly but also happily, caressing the raven hair of his lover.

 

Dan Heng plops down beside Caelus and immediately pulls him into a tight embrace, as If he’s trying to hide the grey haired from the world. Caelus himself only hugs him back and tiredly leaning his head to his lover’s chest. The heat inside both of them finally die down as they sleepily lean more into each other to rest.

 

Fzzztt!

 

“Aah!” “Woah!”

 

“Oh, those kids are back already? That’s fast on your part, Screwllum.” Herta says with her eyes still glued at the monitor, fingers typing out something on the keyboard.

 

“Yes, rewriting the logic and fixing the paths with two living beings inside is a quite delicate task I have to admit. I truly have to rewrite Aha’s code, at the very least, if such things might occur again in the future, the problem won’t be this big.” Screwllum replies as he helps the two confused young men up on their feet.

 

“Then I’ll leave the explanation to you.” Herta says as she immerses herself back at the monitor in front of her.

 

“I uhh… you two…” Caelus wants to say something but he can’t find the right word to ask as his mind is still a mess. The tingling sensation he still feels inside his body doesn’t help either. Dan Heng on the other hand has his hand massaging his temple, probably feeling a bit lightheaded.

 

“I apologize for the situation you two had to experience, both of you will be compensated by us for the trouble. Based on my calculations, both of you won't suffer any damage to your mind and body in the long run, though I suggest you go check on your conditions in the medical wing for safety reasons.” Screwllum explains in a calm manner like always. “Also, Herta and I already agree to delete any sort of recordings inside the Simulated Universe today as part of the compensation.”

 

Both Caelus and Dan Heng’s eyes widen in unison.

 

“WAIT DO YOU-”

 

“Thank you very much for your generosity, Madam Herta, Mr. Screwllum. We’ll leave now.” Dan Heng covers Caelus’ mouth before he can speak any further and drags him outside in embarrassment.

 

“Don’t forget to try the Simulated Universe again once we finish fixing it.” Herta calls from behind which both Caelus and Dan Heng ignore.

Notes:

Fun fact number 1: I forgot to write Dan Heng's biting Caelus at the beginning, so I wrote an excuse as to why he didn't bite later
Fun fact number 2: Caelus is supposed to grow breast too, but I dropped the idea cause it's too much for me to write and I kept laughing

Thank you for reading
