I Had Sex With My Biological Daughter Monmusu
I thrust deep into Frau, my voice hoarse with urgency.
“Frau! I’m gonna cum!!”
“Nngiiiiiiit!! Taehun’s cock is making me cum againnnnn!!”
《Splurt—! Splurt—!》
“Master Taehun~ Please pull your cock out of Frau’s pussy. I’ll clean it with a nice blowjob~ Om nom nom~♥”
“Ah, thanks, Papi…”
I slowly withdrew my Big-Ja from the Alraune Frau’s tight folds.
The moment I pulled out, the Pixie Papi latched onto my shaft and began licking up every thick rope of semen coating it.
Are you enjoying this decadent harem life?
Half right, half wrong.
It is a harem, sure. But I’m technically on the clock right now.
I missed the monster merchant’s village visit last month, so I have to make up for it this month.
The underground storage is packed wall-to-wall with Monmusu eggs, and on Mary Jane’s advice that it still wasn’t enough, I’ve been breeding the girls at least three rounds a day.
“Haa… This is getting a bit much.”
A sigh slipped out along with my true feelings before I could stop it.
Between the goblin raid and the breeding hiatus while recruiting Lady Hariti, we’d fallen behind on production. To catch up, I had to keep this pace at minimum.
On top of that, I was still doing the occasional male prostitute gig on the side to scrape together immediate cash.
No wonder my Big-Ja felt raw and battered.
“Slurp—! Slurp—! Gulp—! Master Taehun! Cleaning blowjob complete!! I ate so well again today!!”
Papi hugged her swollen belly, bloated with semen, and wobbled through the air back to her spot, looking thoroughly satisfied.
Since she’d taken in so much, she’d be laying Pixie eggs in no time.
Haa. That’s it for today’s shift.
I just want to rest now.
“Taehun! Taehun!! Someone’s here to see you nyang!!”
Damn it. No rest for the wicked.
I dragged my exhausted body toward the yard where Mary Jane was calling.
“Who…?”
There was an unfamiliar Monmusu standing in the yard.
Purple hair, blue eyes. And a pair of horns rising from her forehead.
I couldn’t even begin to guess what kind of Monmusu she was…

“I am a Yakshini. Is this the Monmusu ranch belonging to one called Taehun?”
“A Yakshini? Hey, Mary Jane. What’s a Yakshini?”
“I have no idea nyang…”
Mary Jane looked back at me with an equally clueless expression.
Hmm. Definitely not a common Monmusu.
“Yes, this is my ranch. What brings you here?”
“It’s even more shabby than I imagined. For Mother to make me live in a place like this… how cruel.”
“Hey! Yak-whatever! Who do you think you are, calling our Taehun’s ranch shabby nyang!!”
The moment Mary Jane shrieked, the Monmusu who had been scattered around the barn and house began poking their heads out one by one.
“Mary Jane, calm down. You said Mother sent you? Could it be… your mother is Lady Hariti?”
“Oh, correct. You seem rather quick on the uptake. I am the Yakshini who will be staying here from today onward. I look forward to your hospitality.”
This is strange…
I was certain the Monmusu Lady Hariti promised to send was named Rakshasa…
“Yakshini is what you’re called? I was told a Monmusu named Rakshasa was coming.”
“Mother must have called me Rakshasa again. Rakshasa is a male name, so all of us sisters refer to ourselves as Yakshini. I’d appreciate it if you called me that too.”
Ah, so it’s a male name…
I expected a wild tomboy, but she has a surprisingly girlish side.
I led the Yakshini to the newly renovated reception room.
After asking the Silky Jibsun-i to bring us some tea, I returned to find her still standing instead of sitting in the chair I’d offered.
“Why don’t you sit comfortably?”
“I’m fine like this.”
“Then I’ll have to stand too…”
“You can sit. I’m comfortable standing.”
Tch. Not exactly the friendly type.
Guess I’ll try some small talk.
“So, which child are you? Lady Hariti has over ten thousand offspring, right?”
“Hmph, you even know that? According to Mother, I’m apparently the 10,001st.”
“Eh?!”
“Why are you so surprised?”
When I creampied Lady Hariti, she said the child born from that was her 10,000th…
Then this girl is the very first child conceived from my semen?!
Does that mean… I’m a father now?!
“D-do you know who your father is, then?”
“Of course. It’s you, Taehun.”
Ha. We’re definitely going to need a serious talk about family values.
“R-right. Since I’m your dad, can I speak casually to you?”
“Sure. Go ahead. I’ll speak casually too.”
You’ve been speaking casually this whole time.
“Oh, right. Mother said when you meet Taehun, ask him to give me a name. Hurry up and name me.”
“A name? Isn’t Yakshini your name?”
“That’s just what we call all of us sisters. My older sisters all have proper names. Give me one already.”
Haa, I’m terrible at naming things, yet somehow I keep ending up naming people ever since I got here.
Might as well wing it again.
“How about Sinia? Sinia? Since you’re a Yakshini, Sinia.”
It sounds like the kind of name that would make a smartphone AI ask, “Did you call me?” every time I say it, but since this is another world, it should be fine.
Sinia seemed to like it and nodded happily.
Uh… well then. Small talk over?
Time to talk business?
“Alright, Sinia. I think you’d be perfect for security duty around the Monmusu ranch.”
“Hold on. Before we talk work, there’s something I want to confirm first.”
“What is it?”
“They say your cock is huge. And that you produce tons of cum.”
“Hey. Is that any way to talk to your father?”
“Tsk, do you really think we have a normal father-daughter relationship? I’m a Monmusu. I live in a world completely different from the common sense of you Lowlanders.”
“And in that world, fathers and daughters have sex? That can’t be normal.”
“It’s not exactly commonplace, but it’s not taboo either.”
“What?! For real?!”
“Yes. So… can I have a taste of your cock? Security work alone would be boring. I’d like to sample your dick from time to time. How about it?”
I was stunned.
Sinia was well-developed and undeniably sexy, but the moment I thought of her as my daughter, a wave of instinctive rejection hit me.
She wasn’t even adopted—she was my biological child… wasn’t this going too far?
“I’m sorry, but that’s going to be difficult. I feel pretty uncomfortable with it.”
“What~? Don’t be like that~! Does that mean I’m supposed to live my whole life without ever tasting a man’s cock?!”
“You could just find another man…”
“You want to watch your daughter get fucked by some other guy and moan like a whore? If I’m your daughter, then you should just fuck me with your own cock.”
At first I thought, why is she being so extreme?
But when I actually pictured the scene she described… the thought of my daughter writhing in another man’s arms made my stomach twist.
“Ugh, it pisses me off, but… you’ve got a point. I don’t know why I’m even wavering.”
“I’m not asking you to get me pregnant. Just sex. Sex. Okay? How about it, Daddy~♥”
As she spoke, Sinia leaned in and kissed me on the cheek.
Right then, Jibsun-i entered carrying a tea set.
“Already in heat and trying to devour Taehun? Taehun. Are you really going to have sex with her too? When is it going to be my turn?!”
“Ah, well… still, we should at least do the interview. Isn’t a sex interview standard for Monmusu?”
“Tch, fine. Here’s the milk. If the tea’s too bitter, add some. And don’t have sex in here. Last time you fucked Lime in this room and I had to clean up all that slime mucus. It was disgusting.”
“O-okay.”
Jibsun-i slammed the reception room door shut behind her. The moment she was gone, Sinia threw her arms around me tightly.
“Hehe, so we’re doing a sex interview? Daddy’s quick on his feet, huh? Shall we head to the bedroom then? I’ve been dying to try paizuri. Can I do it with you, Daddy?”
“W-wait. Paizuri or whatever is fine, but… don’t ever tell anyone outside that I’m your dad. Just promise me that.”
“Got it. That’s not hard at all. Now let’s hurry to the bedroom!”
The second we opened the bedroom door, Sinia started yanking my pants down.
“H-hold on. I haven’t even closed the door yet.”
“Huh? I was planning to do it with the door open. Why? Were you going to do something perverted to me with the door closed?”
This girl really…
Even while complaining, she didn’t stop and successfully stripped my pants off, freeing my fully erect, rock-hard Big-Ja.
“Wow, I heard from Mom, but it really is huge. I’m putting it between my tits right away.”
With that, Sinia sandwiched my Big-Ja between her breasts and began sliding them up and down.

“There’s already so much precum… doesn’t it feel good sliding so slickly between my boobs, Daddy?”
“Hey, stop calling me Da—… never mind, we’re alone right now.”
“Daddy. This is the cock I was born from, right? Right? I was the very first one made from the cum you produced in these balls, wasn’t I?”
“Y-yeah… that’s true…”
Deciding precum wasn’t enough, Sinia spat saliva into her cleavage.
The added spit made the paizuri incredibly smooth.
“So slippery, so slippery. Right, Daddy?”
“Stop talking in rhythm like that.”
“Geez, you tell me not to do everything. Hard, so hard. Daddy’s cock is so hard, so hard~”
The reason I told her to stop the rhythm was because hearing her say it in that cutesy, aegyo-filled cadence while giving me paizuri made it almost impossible to hold back.
I’d already cum three times today, yet the urge was rising again… my balls must be broken.
“Daddy, if you’re about to cum, tell me in advance. I want to taste your cum, okay? So don’t just suddenly blast it… say something like ‘I’m about to cum, Sinia~’ Got it?”
“Got it…”
I couldn’t hold it anymore.
Oh right, she wanted me to say it.
“I’m about to cum.”
“Huh? You’re cumming now?”
But my climax came even faster than I expected.
Even though it was my fourth load, the semen raced up my urethra at highway speed.
《Splurt—! Splurt—!》
“Kyaaak—! Daddy!! You said you were going to cum and then you just did it right away!!”
“S-sorry…”
“Jeez… how did you even have sex with Mom like this? Isn’t our mom super scary?”
“Ugh, I wouldn’t know about that…”
I was in no state to answer her barrage of questions.
This had been the most pleasurable ejaculation of the day, and I’d released the largest amount of semen yet.
It felt like the ecstasy and relief that followed scaled directly with the volume.
“Ah~ Daddy, you’re having a post-nut clarity moment, aren’t you? Take a little break. I’ll clean your cock for you. Slurp—! Slurp—! Chuuup—!”
Sinia began sucking my Big-Ja with devoted care.
After thoroughly cleaning it, she scooped up every drop of semen splattered across her body and licked it off her fingers.
“Sorry, my little siblings~ Daddy’s only going to have sex with me from now on~”
“Don’t call the sperm your siblings…”
“Whatever~ Anyway, Daddy! Should I ride you this time? Or do you want missionary?”
“The sex interview is already over. What more do you want to do?”
“The interviewer might be done asking questions, but I still have tons of things I want to do.”
With those words, Sinia shoved me backward onto the bed.
Then she slowly lowered herself, guiding her pussy onto my still-hard Big-Ja.
“Ugh, this is the cock you just came with? It’s still so fucking hard… feels amazing…”
“Sinia, I just came. There’s still leftover semen inside. What if you get pregnant?”
“Who cares about that right now? Daddy, don’t even think about pulling out.”
She said it while steadily increasing the pace of her riding.
