No Puppies, Only Growing Colts Rule Here
The chilly morning air settled over the track field.
A beautiful girl with a long golden ponytail was running in place alone.
Every time her thick, pumped-up thighs and slender calves struck the ground, the toned body wrapped in her athletic uniform bounced up lightly like a ball.
“Huu… huu… huu…!”
Yang Hye-in’s eyes were filled with the long track stretching before her.
A place that had once been nothing more than her playground, but now had become a heavy burden.
Just finish this, and I can do those lewd things with Yeon-ssam. I should just focus on that.
The speed of her in-place running gradually increased, and soon— Yang Hye-in’s body had positioned itself at the starting line of the track in an instant.
She drew a virtual starting signal in her mind.
Three… two… one…
“………!”
Even though the loud starting signal had sounded, Yang Hye-in’s feet stepped forward a full beat late.
Realizing she had already failed before even trying to run further, her body took a few empty steps and then stopped immediately.
At the end of it all, today too, Yang Hye-in stood with her knees on the starting line, eyes tightly shut.
Still no good. I can’t do it…
Yang Hye-in had tried to catch two hares at once—one being the chance to do lewd things with Yeon-ssam and the other being the recovery of her track record.
But because of the weight of her greed, her legs had only grown heavier.
The practice had been more than enough. No, it had been overflowing.
Yet… when she truly ran the track, she feared she would never reach her old record.
If she truly could not reach it, not only would her dream of becoming a track athlete vanish, but the lewd things with Yeo-eun would be completely impossible too.
She feared that would actually happen.
The heavier her feet became, the more she felt depressed, and the more depressed she felt, the heavier her feet became.
An endless cycle of despair had her in its grip.
I want to be spoiled by Yeon-ssam…
But she could not tell her teacher about these worries.
I was running hard to do lewd things with carrots because I wanted to please Yeon-ssam, but then my legs got even heavier because of the promise— that was what she would have to say.
At the time, she had only set conditions to turn Yeo-eun’s heart away from forbidding carrots, but she never imagined it would make her even farther from the carrots.
With stress piling up, the colt became even more eager to do those lewd things with Yeo-eun and the carrots.
Yang Hye-in let out a deep sigh, hesitated, then suddenly brightened her eyes and straightened her waist.
“Now that I think about it, Yeon-ssam did say something like that, right?”
It was because a carrot would appear and the teacher would have to handle it— that was the catch.
She had set a condition for deliberately creating carrots for lewd things, but when a carrot appeared accidentally, there was no condition.
Even though she knew this was like betraying and deceiving Yeo-eun, Yang Hye-in had already reached the point where she could not hold back any longer.
Right now, more than anything, she needed a carrot more than ever.
Yang Hye-in took out her phone and began tapping the screen lightly.
On her face, a rare happy smile had appeared.
***
How did I end up doing lewd things with Hee-ji again the next day after crossing paths with Hye-in?
But thanks to that… I feel like I finally understand exactly what I should do from now on.
Seeing my secret private life with Jeong Si-young was truly a terrifying memory, but her advice still seemed genuinely helpful.
…Still, I worry that I’ve become too familiar with futanari penises.
Me, Hye-in, and Hee-ji too… if we keep sharing this special bond, won’t we get too used to it?
After our connection ends, can I ever meet normal people normally again?
But isn’t it a bit strange to say that after doing those things to me and then graduating, I can just casually meet someone else?
“……….”
Alone, imagining whatever I wanted, I stared blankly at the photo of Yang Hye-in and Kang Hee-ji displayed on my monitor, then slowly began filling in their documents one by one.
1. Yang Hye-in
At first, there was some slight lack of diligence, such as skipping classes, but… it turned out to be due to the slump caused by her declining track records.
I even tried offering special rewards for motivation, but no noticeable results had appeared yet.
Additional care seemed necessary.
2. Kang Hee-ji
Her relationships with classmates were harmonious, and she showed a kind personality that followed the teacher closely and wanted to help.
She had shown excellent results even in classes like arrest-and-self-defense techniques, and the supervising teacher’s trust in her was very deep.
A perfect student, but… wasn’t she pushing herself too hard? It might be necessary to watch her a little more closely.
“Huu….”
After I came to Lily Academy and thought I had been working hard, writing it all down like this revealed it was actually just a few lines.
Am I actually helping them properly?
Our golden colt seems psychologically a bit more stable, but she still hasn’t escaped the slump.
Our spotted dog colt has been perfect since before I even offered any help, so I worry she might be developing strange things because of me.
And our cat…
I’ll have to make her come back to the academy too.
But before Go Yeon-hui, Jeong So-hye and Woo Ha-neul still hadn’t been properly looked into at all.
I stared at the empty space under Go Yeon-hui’s name and tapped my keyboard anxiously.
Helping them was for my students, but it was also for me.
If I show my colleagues that I am successfully caring for my students, they will trust me,
and I will be able to uncover the secret of Lily Academy—the shooting star that led me to this world, the cat-eared shooting star logo.
After hesitating for a moment, I picked up the phone from the desk and sent a message to Go Yeon-hui.
[Yeon-hee, it’s Yeo-eun Sunbae. If I come by your house this weekend, is that okay?]
After a short while, a read receipt appeared, and after about ten minutes, a short reply came back.
[Got it.]
[Yeah, thanks! I’ll buy something delicious for the teacher.]
[Don’t bring any of that this time. If you do, I’ll kick you out.]
With the message that no reply was necessary, the first message exchange with Go Yeon-hui ended in an instant.
But who would ever talk normally without a weapon in hand?
Thousands of miles start with one step— so I had already taken two.
And since the puppy tour is probably enough for now, let’s move on to career counseling next. The colt was sulky that I skipped the tour, so I’ll go on one… and the cow and wolf classes should probably get tours too…
But I have five thousand-mile routes I need to walk.
How are the other teachers even doing their teacher duties?
Peeking through the partition into the staff room, I saw the other teachers either calling someone or reading a screen full of English papers earnestly…
Even Dam Si-a, who was much smaller than me, looked professional while taking notes while talking on the phone.
Of all of them, I looked the most relaxed.
…I’m the only one who can do this.
Of course, it wasn’t about the futanari-ization story.
As a part-time teacher, I could do this: approach the students at a lower level, more closely… look at them from their own eye level.
I should do my best at what I can do.
Time for the closing bell soon.
I sprang up from my seat, grabbed the attendance book with enthusiasm, and left the staff room.
While Dam Si-a stared at my retreating back without my noticing.
***
“Everyone, thanks for your hard work today too.”
After the closing bell, I always stood at the door to see my students off.
Doing this consistently seemed to have some effect; even the blunt Woo Ha-neul nodded slightly toward me.
Jeong So-hye wrinkled her face as if annoyed, but after making eye contact with me, she turned her head with a “Hup—!”
…Was that her own way of greeting? Probably.
“Yeo-eun Sunbae, I’m heading out. Today… was really good.”
“G, good. Take care.”
Even today, I was worried that Hye-in would cling to me all day and never let go, but luckily Hee-ji went home quietly.
She had said she was scolded because she hadn’t gone home in days, but for some reason… the eye contact was clearly less tense after hearing the futanari-ization story.
Maybe because we had sex.
No matter what, it was good that I could finally relax.
When Hee-ji kept sticking to my side, her every action felt so fidgety and my heart raced…
Of course, that didn’t mean I was in love with Hee-ji. It’s not like I fell for her like some charming woman… yeah, definitely not.
The racing heart came from simply being surprised that she unexpectedly showed care for me in a place I never expected.
Yeah, that was it.
“What are you thinking about so hard, Yeon Sunbae?”

Yang Hye-in’s voice woke me up from my daze, where I had been lost in thought while unconsciously recalling Kang Hee-ji’s face.
“Ah, Hee… Hye-in-ah.”
“……Hee?”
“Huh? No, I said Hye-in. Hye-in.”
Yang Hye-in looked at me suspiciously, ears twitching, but luckily I quickly deflected, and she let the doubt go and backed away.
“But why…?”
“Why? You weren’t greeting me?”
“Ah, right. Yeah. Take care, Hye-in.”
“This isn’t like prostrating and receiving beating either… By the way, are you okay with your body?”
“Body?”
Yang Hye-in looked around as if searching for traces of the Kang Hee-ji who had been clinging to me lately, then stared up at me.
“Yesterday, you were sick and resting, right? I didn’t send a message because I was worried about bothering you with my pain.”
She tidied her long ponytail like its tail while glancing at me sideways.
…Such a cute colt.
Seeing my mouth corners curving up, Yang Hye-in turned her head away shyly, but she seemed completely unaware that that was even cuter.
Still… I felt apologetic toward her.
I had been like a wall around Hye-in: “The futanari-ization is bad! Don’t do it!”
Yet now that teacher had done lewd things with her friend after drinking.
Of course I had no crazy idea of treating Hye-in fairly with sex, but guilt could still surface.
“……Huh? What is that?”
“That?”
“Here, on the neck.”
Yang Hye-in touched my neck, and I blinked blankly because I felt nothing special.
Then I remembered.
The place she was touching was where I had been bitten by Kang Hee-ji in the back warehouse… the place I had sucked on with my lips.
So what Yang Hye-in was looking at was— the kiss mark left by her friend.
I jumped back in shock.
“I, it’s… maybe a mosquito bit it!”
“A mosquito in this weather?”
“H, maybe one or two… anyway, it’s nothing. Yeah.”
“Strange. It doesn’t look particularly swollen if it was a mosquito bite.”
Even in my explanation, Yang Hye-in stared fixedly at the kiss mark with a puzzled look, tilting her head sideways repeatedly.
“By the way…! Today… um, did running go well today?”
“……….”
The question I had hastily asked to change the topic had poked a bad spot; Yang Hye-in’s expression darkened instantly.
“I try hard to get a reward from Yeon Sunbae… but it doesn’t suddenly make me run better just because of that.”
“I, I see….”
“…Yeon Sunbae, what if you just prepay me? Then I could try even harder.”
“Even so, the promise is a promise.”
Guilt was guilt, and the promise was a promise.
Moreover, even if I suddenly fulfilled the futanari-ization as a reward, it would only make the reward meaningless and provide no help.
Yang Hye-in let out a sigh as if saying she had only spoken aloud, then slipped closer to me.
The warm body heat that was uniquely hers made my arm tingle.
“So do you have time today? I… normally when my running doesn’t come together, my routine is to go watch a movie. …It doesn’t help much, but it clears my head.”
“You’re saying to go watch a movie?”
“Right. A date with Yeon Sunbae too. …I think it would give me strength.”
Yang Hye-in’s mouth corners lifted weakly, forming a very tired smile.
As a teacher, I could not just stand by such an expression.
Then, Yang Hye-in’s fingers gripped my collar tightly.
“I won’t ask you to do lewd things with me. Just… can you do something like this instead? I know it’s unfair for a girl like me who can’t even run to take up Yeon Sunbae’s precious time….”
“Ah, no! Of course it’s fine, why wouldn’t it be? The teacher’s time is always for our students.”
“Really…?”
Looking into eyes that were so sad they looked like those of someone whose last wish was to see their owner, I nodded my head until my neck ached.
“Then, then! We can watch a movie today, and the teacher will buy delicious meat. Eat as much as you want, Hye-in.”
“Thank you so much, Yeon Sunbae. Just being with Yeon Sunbae makes me feel like I can gain so much strength….”
“If the teacher can be strength for Hye-in, that’s actually the teacher who should feel grateful. Come on, let’s go quickly! Oh, wait, did you reserve the movie tickets?”
I had said we’d watch a movie, but if I had no tickets, that would be a problem.
Luckily, Yang Hye-in immediately nodded.
“I already reserved two tickets. Since it’s the nearby theater, we just need to go within an hour.”
“Well done. Let’s go ahead and buy popcorn while waiting.”
“Okay, Yeon Sunbae…!”
While hugging the slender body of Yang Hye-in to my chest, I suddenly recalled something.
…Wait, she had already reserved two tickets?
Coincidence… right? Maybe she was taking me to the movie with a friend, or something like that…
“Yeon Sunbae, let’s go quickly. If Hee-ji shows up, it’ll get annoying.”
“Ah, yeah.”
Thus, led by Hye-in’s hand, I went on a movie date to cheer her up.
I had no idea that at that place, I would experience yet another first for myself.
