Centaur Doggy-Style Breeding
「Mary Jane.」
「Yeah. Taehun. What's up nyang?」
「No way… that Monmusu over there… is a Centaur?」
Mary Jane raised her right hand to shade her eyes and squinted in the direction I pointed.
「That's right nyang! Taehun. Can you see that far nyang?! Is she from the Mongol tribe nyang?!」
「No… more importantly, that Monmusu… can I even breed with her?」
「Kyaha-! What are you saying nyang, Taehun! There's nothing impossible in this world nyang!! Let's go nyang!!」
Mary Jane grabbed my wrist and half-dragged me into the post station.
Inside, the station staff were busy sorting wooden crates, working frantically.
Even though we had entered, no one paid us any attention; everyone looked overwhelmed with work.
Mary Jane skillfully dodged the staff's paths and walked ahead.
She reached the door at the very back of the building, knocked twice—knock knock!—and opened it without waiting for a reply.
「Karel-ssi! I'm here nyang~!」
「Oh, Mary Jane, you've come. Welcome. About the request I mentioned last time… Ah, welcome. You're Taehun-ssi, correct?」
An elderly gentleman with white hair and deep wrinkles, yet a warm and friendly expression, greeted us.
This must be Karel-ssi, the station master Mary Jane had mentioned.
「Hello. Nice to meet you. I'm Taehun.」
「Pleasure to meet you. By the way, Uma seems to be in heat today—she's been quite troublesome since morning. This morning she even urinated on me, you know? Hahat. That's why I just finished changing my clothes.」
「Urinated… on you?」
Karel-ssi pulled out a guest chair from the office and offered me a seat before continuing.
「When a mare enters heat, she urinates frequently. Today it was especially bad, so she ended up wetting herself right in front of me. Haha. Yesterday she even spread her own pussy to show me—honestly, that made me think I should call Taehun-ssi right away.」
「Uma's completely in heat nyang!! Taehun, let's hurry and breed with Uma nyang!!」
「W-wait a second. But… earlier, the Monmusu I saw, the one called Uma…」
Karel-ssi suddenly stood up mid-sentence, grabbed the tea set from the table, and returned to his seat.
He poured tea while gesturing for me to continue speaking.
「Ah, yes. To continue… her upper body is human, but her lower body is a horse.」
「That's right. All Centaurs are like that.」
「Then… her reproductive organs… I mean, her pussy… isn't it a horse's pussy?」
At that moment, both Karel-ssi and Mary Jane burst into laughter at the same time.
The laughter was uncontrollable and lasted for a while.
Karel-ssi managed to hold it in eventually, but Mary Jane was different.
She laughed so hard she cried and clutched her stomach, looking almost in pain.
「Aah, my apologies. It's only natural you wouldn't know, being a Lowlander. But you don't need to worry about that. In this world, nothing is impossible.」
Huh? Wasn't that exactly what Mary Jane just said?
「Kyaha-! Taehun. My stomach hurts so much nyang!! It's all because of you nyang!! Anyway, don't worry and let's go to the stable nyang!! Let's go see what a horse pussy looks like nyang~!! Kyahahat-!!」
I mouthed “Is this fun?” at Mary Jane before following Karel-ssi to the stable.
The stable was a little distance from the post station, with a pasture between them where horses could graze on fresh grass.
「Once you go inside the stable, only Uma will be there. Please talk with her and have a pleasant time. Goodness, that sounded like something a brothel owner would say. Hahat. Please take good care of Uma.」
Karel-ssi bowed politely and headed back the way we came.
Mary Jane, apparently unaware that I wasn't mentally prepared yet, flung the stable door open.
Inside was… the Centaur I had seen from afar when I arrived at the station.
Brown hair tied in a ponytail, as expected of a horse.
Breasts that looked like H-cups, a slim waistline.
And below… just a horse. Hiiing-! A real horse.

「Kkyahho-! Uma, have you been well nyang?!」
「Mary Jane, hi!! Long time no see! What brings you to the station?」
「Hehe. I heard you peed on Karel-ssi today nyang?! I came because I heard you were in heat nyang!」
「Oh my, Karel-ssi even told you that?! How embarrassing…」
The Centaur called Uma began blushing on her cheeks.
Wait, isn't standing there completely naked more embarrassing…?
「Ah-cha-cha, this is Taehun, who's going to help Uma with mating today nyang! He's Vojtech-nim's one and only son nyang!!」
「Vojtech-nim's son?」
Uma circled around me slowly, her hooves clopping against the ground.
「Now that I look at you, not just your appearance, but your scent is very similar to Vojtech-nim's.」
Well, that was probably because I slept in the bed my father used and wore the clothes he left behind…
「Taehun. That's not all nyang. Even when I'm with you, sometimes Vojtech-nim's scent comes off you and it surprises me nyang.」
This was getting complicated. I kept forgetting that Mary Jane could read my thoughts.
I shouldn't think weird things.
「Then… would you please mate with me? Taehun-ssi? If someone like me is acceptable…」
「Ah, um…」
I couldn't answer easily.
「Taehun. Why are you like this nyang? That's not like the perverted Taehun who says yes to everything nyang.」
Hey, Mary Jane. Is that supposed to be comforting?
「Then Taehun-ssi. Would you like to smell my urine first? I'm sure your mind will change. Definitely.」
「Huh? Smell your urine? Horse urine… I mean, Uma-ssi's urine?」
「Yes yes. It's a bit embarrassing, but I'd really like you to smell it!!」
I stared at Mary Jane in disbelief.
Mary Jane just shrugged as if to say “Why are you making that face?”
「Taehun. Just smell it nyang. If you really smell it, your thoughts will change nyang!!」
If even Mary Jane was saying this, there must be something to it.
Yeah, I needed money for the ranch anyway, and to earn money I had to breed with Uma.
「Alright. Then please… pee.」
「I'm so happy!! Then would you come behind me? If you're too close, the urine might splash, so please keep some distance and come closer to smell my pussy and urine after I'm done peeing!!」
「O-okay.」
Suddenly the genre had shifted to golden shower territory and I was extremely flustered, but since I wasn't going to get peed on or drink it… smelling it should be fine, right?
Thinking that, I stood a short distance behind Uma.
「Eung, I'm going to pee now. Please watch my twitching pussy closely♥」
Uma wiggled her hips seductively, spread her clitoris, and began urinating.
《Shhhhhhhhhhhhhh-!!》
《Tatatatatatatatatat-!!》
It was an incredibly powerful stream.
Uma's urine hit the stable hay and splashed droplets in all directions.
So that's why she told me to stay back.
This wasn't a normal piss stream.
「Haa haa, Taehun-ssi. I'm done. Come quickly and smell my pussy and urine…」
「Ah, yes.」
I hesitantly approached Uma's pussy and brought my nose close.
《Sniff-! Sniff-!》
At first, I felt nothing.
But on the second inhale… a strange reaction began in my body.
Suddenly my upper lip curled up and I started laughing.
And in my lower half… Big-Ja, which had been flaccid until now… instantly became fully erect, threatening to burst through my pants.
「Hihihit, w-what is this. Hihit.」
Unable to hold back laughter, I desperately tried to suppress it while looking to Mary Jane for help.
Mary Jane casually spoke to Uma.
「Uma! You were really desperate for mating nyang?! There must have been an enormous amount of pheromones in your urine nyang!!」
P-pheromones?!
Come to think of it, I had seen in animal documentaries how animals make funny faces after smelling the female before mating… was I making that face right now?
Given that Big-Ja was fully erect, Uma's urine definitely contained powerful pheromones.
「Taehun-ssi. How is it? My urine smell? Oh my, Taehun-ssi's cock… Huhu. Go ahead and take it out.」
As if possessed, I followed Uma's words and threw off my pants.
My underwear was already soaked with precum, and once I removed it too, the stable filled with the scent of Uma's urine and my precum.
But… could I really put it in a horse pussy?
Having sex with a beastkin was completely different from bestiality…
Just then, my vision blurred for a moment…
Gradually, Uma's appearance began to change.
Her legs gradually turned white and shortened… and when the blur completely cleared, they had transformed into human legs.

「Wait, did I eat something weird… Are there some kind of ingredients in the pheromones?」
「Ooh, it seems the effect is already kicking in nyang!! Taehun, you're seeing the effects of Uma's pheromones right now nyang! Does Uma look like a human woman right now nyang?!」
「Well, calling her a human woman… she still has a tail and hooves, but… her pussy is human.」
「Hihit. Then that's correct nyang. Uma likes doggy-style nyang, so Taehun, run over and pound her nyang!」
「That's right, Taehun-ssi. Here, I have the pink pussy you like. I'll spread it wide open, so shove your cock in deep~」
With those words, the now-human Uma spread her ass and showed her pussy wide open.
Her pussy was glistening with a mix of the urine she had just released and her love juices, sparkling as sunlight streamed into the stable.
Was it because of the pheromones that it looked as beautiful as a jewel?
Without further delay, I grabbed Uma's hips and started pounding her from behind.
《Thwack-! Thwack-! Thwack-! Thwack-!》
Only the sound of flesh slapping against flesh and Uma's rough breathing echoed through the stable.
To think a horse pussy could feel this good.
Well, it wasn't a horse pussy anymore.
Until now I'd only done missionary, but doggy-style felt amazing too.
Especially the way her ass jiggled every time I thrust—it was visually violent.

「Taehun-ssi, eung. Ahng. Don't just thrust… bite my neck too. Okay?」
「Huh? You want me to bite your neck?」
「Taehun! Do what Uma says nyang!! Centaurs originally like to lightly bite the mare's flank or neck during mating nyang.」
Following Mary Jane's words, I lightly bit Uma's neck.
「Hiiiiiing-!! It feels so good, Taehun-ssi!! Your cock already tastes amazing, but when you bite my neck too, it feels fucking incredible!!」
Uma was so excited she started spouting strange words.
She even mixed in swear words… but personally, I liked it.
「Yeah? Then I'll bite you more. Since you're eating my cock, I'll eat your nape.」
And when I bit Uma's neck again, I felt her pussy suddenly tighten sharply.
「Hiiing-! I love it, Taehun-ssi. No, honey. From now on, fuck me every day!! Fuck me every day and fill me with cum pyut pyut-!!」
「Fuck, got it. In exchange, you have to keep spreading your pussy like this every day.」
「Hing-! I like it, I like it. I'll spread my pussy and drip urine every day!! Ahng-!」
Uma squeezed her pussy tight, turning it into a narrow grip, and the urge to cum rose rapidly.
「Uma, I'm cumming inside. I'll fill you with so much cum and knock you up!!」
「Yes, I like it. I want to make our baby! I want to get pregnant like a slut with Taehun-ssi's cum!!」
「Ugh, here it comes!!」
《Byurut-! Byurut-!》
I poured my semen deep into Uma's pussy.
The cum filled her womb to the brim and began overflowing from her entrance.
「Jealous nyang…」
Mary Jane muttered something to herself, but I didn't catch it properly.
I was too busy savoring the afterglow of my intense sex with Uma.
While I was lying on Uma's back enjoying the lingering pleasure, the stable door creaked open.
「Oh, Uma! You finally mated. Now you won't destroy the stable anymore, right?」
It was Karel-ssi.
Don't tell me he didn't go back to the station and instead eavesdropped on our sex?
「Yes, Mister. With this, I can get pregnant for sure. Thank you for calling Taehun-ssi.」
「What are you saying? Aren't you a very important employee of our station? As part of employee welfare, you can request mating anytime. Isn't that right, Taehun-ssi?」
「Haa, haa. Yeah, well. As long as you pay.」
It sounded way too much like I was a male prostitute, but it couldn't be helped.
I needed money to save the ranch right now.
Later I found out that when I said that, Karel-ssi thought I was a diligent young man.
Uma got pregnant with my semen and gave birth to a beautiful foal.
It was a pretty pony Centaur who looked just like Uma.
And that Centaur coming to our ranch happened several months later.
