==============

"Here, this is the elementary school I attended until the spring of the year before last."

Ruki had guided me to a nearby elementary school playground. Despite it being a holiday, several children were energetically running around. Perhaps the playground was open on weekends, or maybe there was some club activity going on.

"Year before last... so that's pretty recent, huh..."

As I looked at Ruki's mature physique, I remembered that just a little over a year ago, she had also been an elementary school student. Imagining her with that figure carrying a backpack made me feel an incredible sense of incongruity.

"Ruki-senpai!"

Then, three girls noticed Ruki and came running over. They were elementary school girls, around third to sixth grade, wearing track uniforms similar to Ruki's. Apparently, they were her juniors in the track club.

"These are my juniors from the track club. They train hard even on holidays, taking advantage of the open playground."

Normally, elementary school club activities are done in gym clothes. Yet, these girls were dressed in full-fledged uniforms. It seemed like they were taking this club very seriously.

"Hello!"

The girls all bowed politely. Their manners seemed well-taught.

"Let me introduce you all. This person is a track coach who has even represented Japan in international competitions. He might look like just an ordinary office worker, but his coaching skills are said to be top-class in Japan. Today, he's going to teach you all some tips on how to run faster in sprints."

"Huh?"

Whose name was she even saying? I understood when I saw the admiring gazes of the girls. Apparently, Ruki was trying to pass me off as a track coach.

"P-pleased to meet you!!"

The girls bowed deeply again, now completely convinced I was a track coach.

"Hey, what are you trying to pull? I've never even done track before."

I whispered to Ruki so the girls wouldn't hear. Not only had I never done track, I'd never even been in a sports club. I was purely a humanities guy.

"It's fine, it's fine. Just go along with it for now."

What was she planning? Ruki gave me an exaggerated wink. It was infuriating how cute she looked doing it.

"Alright, let's start with warm-up stretches! Everyone, stretch more carefully than usual!"

Clapping her hands, Ruki got the girls to start stretching with serious expressions. Being young girls, their bodies were incredibly flexible. Meanwhile, I could barely manage a 90-degree split.

"Kanako-chan, you're still stiff as ever. Bend your upper body more."

"Y-yes!"

The middle girl in terms of age and height was struggling to bend further at Ruki's instruction. Honestly, compared to me, her flexibility was amazing, but among the three, she was probably the least flexible.

"Still too stiff. Sensei, push her from behind."

"Eh?"

Almost forced by Ruki, I ended up pressing the girl's back. I couldn't refuse, so I hesitantly placed my hands on the elementary schooler's back. I could feel her body tense up. She was nervous—thanks to Ruki's unnecessary lies. The girl's back was small and slender. Even though she was only about two years younger than Ruki, she was unmistakably still a child.

"Sensei... how is it?"

As she bent sideways, the girl timidly asked for feedback. I had no idea about proper stretching techniques, but at this point, I had to say something plausible to keep up the act.

"!?"

But in that moment, I realized something.

Just like Ruki, these girls weren't wearing any underwear either.

From their sleeveless uniforms, their budding sideboobs peeked out intermittently. Though small, the slight swell of their developing chests was unmistakable, jiggling with every movement, barely concealing their tips.

The other girls were the same.

The oldest girl exposed soft-looking cleavage to the sunlight with each squat. The youngest girl, likely just starting to develop, emphasized her budding chest as she arched her back during stretches.

This place... was pure heaven.

Was it their policy not to wear underwear under their uniforms? Or were they simply too young to bother? At the very least, the older two definitely had something resembling "breasts." Compared to Ruki or Aika's, they seemed small, but for elementary schoolers, they were well-developed. The oldest girl even had a noticeable curve to her hips. Seeing these girls stretching in near-naked uniforms was almost too much for my eyes.

"Alright, that's enough stretching! Next, we'll move on to practical training!"

I was relieved when the nerve-wracking stretching session ended. Unlike the stretches, where I could mostly just watch, actual training would expose my complete lack of knowledge. I had to somehow maintain my authority as a "coach."

"Today, I've brought a special medicine to help you all run faster."

We moved to a secluded area behind the storage shed, where no supervising teachers were in sight.

"Special... medicine?"

The girls tilted their heads in unison. "Wait, is this doping?" I thought to myself, completely missing the point. That's probably why I didn't notice Ruki's hand sneaking toward my waist.

"!?"

In an instant, my penis was exposed to broad daylight. Ruki had pulled my pants down.

Neither the girls nor I could process what was happening. For them, this was likely their first time seeing a male organ. They might have seen their fathers' when they were younger, but for girls entering puberty, this was an unfamiliar sight.

And to make matters worse, I was already half-hard from the earlier stretching. My semi-erect penis was nearly parallel to the ground.

"If you drink Sensei's 'penis milk,' your time will improve by at least 0.1 seconds."

A murmur spread among the girls. I had no idea what kind of logic that was, but Ruki seemed determined to rope them into this.

There was no way elementary schoolers would engage with something so grotesque—right?

"...I'll try it."

The oldest girl stepped forward.

"I'm Shizuno Yamamura, Class 3, Grade 6. Nice to meet you."

Tall and tanned like Ruki, her long hair was tied into twin tails, fitting for an elementary schooler. Her features were undeniably childlike, unmistakably those of a young girl. Among the three, her chest and hips were the most developed, making it hard to know where to look.

Perhaps feeling she had to set an example for the younger girls, she hesitantly approached.

"How... how do I get the 'penis milk' out?"

Hearing such innocent words from a pure elementary schooler nearly pushed me over the edge. My half-hard penis grew even stiffer, pointing straight up.

"You just have to stroke it like this. Or you can suck it directly, like milking a cow."

Ruki made an obscene gesture as she explained. Most people have never milked a cow, but Shizuno seemed to grasp the idea. She wrapped her small hand around my erect shaft and delicately took the tip into her mouth.

"Mmm..."

At that moment, an overwhelming sense of guilt and depravity surged through me. Despite her mature appearance, she was still an elementary schooler. A girl who probably still carried a backpack was now sucking my cock.

In the past few weeks, I'd experienced blowjobs from middle schoolers, but this was my first time with an elementary schooler. Her movements were clumsy, but like with Anna-chan, the sheer taboo of it was electrifying. We were in a blind spot from the school windows, but getting a blowjob from an elementary schooler on school grounds was undeniably criminal.

Eventually, my penis reached its limit.

"Ngh—!"

I ejaculated thick semen into the young girl's mouth. She tried to spit it out reflexively but stopped herself, remembering the lie about improving her running time.

Tears in her eyes, Shizuno-chan desperately swallowed every drop.

I never imagined I'd experience a "gokkun" blowjob from an elementary schooler.

"Alright, Kanako-chan, you're next."

"Y-yes!"

Following Ruki's instruction, the girl I'd helped stretch earlier stepped forward.

"I'm Kanako Kurasaka, Class 2, Grade 5."

She had her hair in a ponytail. Compared to Shizuno-chan, her body was more childlike, but her chest and hips were already surprisingly shapely for an elementary schooler.

"This Sensei produces more milk if you show him your boobs."

"M-my boobs...?"

Blushing but obedient, the girl lifted her thin uniform, revealing small, palm-sized breasts. Though modest, her nipples were already puffy, showing signs of maturation. Even at this age, her body was clearly developing.

"Sensei, will this make you produce more milk?"

Exposing her budding chest, Kanako-chan began stroking my penis. Having watched Shizuno-chan, her technique was slightly better. The firm yet soft feel of her small breasts and pink nipples was irresistibly cute. Though small, her nipples were perky and tempting—I couldn't help but want to squeeze them.

"Come on, the rest of you, show yours too."

Urged by Ruki, the other girls also lifted their uniforms. Shizuno-chan, being in sixth grade, had the largest breasts—big enough to warrant a bra. She even had slight cleavage, rivaling an adult's. Her nipples were larger than Kanako-chan's and a pale pink.

The youngest girl, likely a fourth-grader, was just beginning to develop. Only her nipples were slightly swollen, with her breasts still small. But the curves of her body were distinctly feminine, hinting at the changes to come.

What started as Kanako-chan's handjob soon escalated into a triple blowjob from all three girls. Taking turns or working together, they licked and sucked every part of my fully erect penis. Pressing my throbbing tip against their soft nipples made them let out faint moans. Even at their age, their bodies could feel pleasure. Their flushed faces and heated expressions made it clear they were aroused—no, downright horny.

"Time for the finale. I'm going to have Sensei cover you all in his 'penis milk.'"

"C-cover us...?"

Confused but not stopping, the girls continued their ministrations. By now, they were fully enthralled by my cock, the "faster running" excuse long forgotten.

"Alright, use your hands to stroke Sensei's penis and balls."

At Ruki's command, the girls began simultaneously jerking me off, sucking, and massaging my balls. A sixth-grader, fifth-grader, and fourth-grader, all topless, fervently attended to my erection.

Shizuno-chan hesitantly took the tip into her mouth, Kanako-chan licked along the shaft, and the youngest girl focused on my balls. All while their soft, budding breasts were on full display. When I experimentally cupped their small mounds and pinched their perky nipples, each girl let out a faint moan, squirming under the sensation. Even at this age, they could feel pleasure.

The elementary schoolers' service continued. With their developing chests exposed, they eagerly awaited my climax.

It was pure bliss.

—Squelch!

"Kyaah!"

I unleashed a massive load, covering all three girls in my cum. Innocent, childlike elementary schoolers were now stained with my lewd fluids. Their hair, faces, budding breasts, and nipples were drenched in sticky white. Normally, this kind of defilement would happen years later—in middle school, high school, or even college with their future boyfriends. But I, an adult, had taken that first step for them.

The guilt and depravity were overwhelming—far worse than with Aika or Anna-chan. Yet, at the same time, the excitement was unparalleled. I had just defiled girls who still carried backpacks to school with my sperm. Innocent children who likely didn't even understand what sex was.

"Rub this all over your bodies, and you'll run faster."

Dazed, the girls obediently smeared my cum on their skin. One of them, perhaps unconsciously, rubbed it over her swollen nipples, making them stand even stiffer.

"Sensei! Thank you for the 'penis milk' and your guidance today!!"

Once they'd redressed, the girls returned to their training, seemingly fully believing Ruki's lies.

"Is this really okay?"

I confronted Ruki. This prank had gone too far.

"It's self-hypnosis. If they believe it'll make them faster, it might actually improve their times."

"Self-hypnosis...?"

I'd heard of the placebo effect, but this was pushing it.

"Besides, learning blowjob skills now will make them promising in the future."

"Promising at what...?"

By the end, the girls had been begging for my cock like little sluts. Even at that age, they must have instinctively understood the pleasure of sex.

"They come here to train on Sunday afternoons, so you can visit anytime and do whatever you want. I bet they'll start asking for your 'penis milk' on their own next time."

Imagining all the elementary school track girls calling me "Sensei" and eagerly swarming me made me feel strange again.

"Or do you want to give me some 'penis milk' too?"

As if reading my mood, Ruki cutely begged for attention. Though still a middle schooler, compared to the elementary girls, her curves were on another level, making her look even more obscene.

"Geez, your dick's so energetic, old man. You can cum over and over."

"...Got a problem with that?"

"Nope. I love it."

She probably meant my penis, but her words made my heart skip. Then, as usual, she exposed her tanned D-cups and began a titty-fuck blowjob.

—Schlick, schlick.

Honestly, her technique was leagues above the elementary schoolers. Her tongue expertly teased every sensitive spot—the frenulum, slit, underside, balls—guaranteed to bring any man to orgasm. It was almost a natural talent.

"You can't grope the elementary schoolers' boobs, but you can squeeze mine anytime."

Looking up at me with a mischievous smile, Ruki used her ample breasts to tease my cock. Her devilish act was betrayed by her rock-hard nipples—she'd been turned on watching the girls service me.

"Aika... she doesn't want to monopolize her dad."

While continuing her titjob, Ruki suddenly brought up Aika.

"Actually, she wants to share him—with girls like me and Anna who don't get much paternal love. That's why she doesn't get mad when we suck your dick. It's about receiving fatherly affection."

I could tell she was serious, but Ruki's blowjob felt too good to focus. How could she give such a skilled titjob while having a deep conversation? She was too talented.

"But when it comes to penetration or creampies, things get more complicated."

"Complicated...?"

Now she was even fingering my ass, pushing me to the brink. Despite only one person servicing me, her hands, mouth, and breasts worked in unison, overwhelming me from multiple angles.

"If me or Anna let you inside us, it's no longer a pseudo-father-daughter relationship. We've already started our periods—it'd be outright procreation. Aika won't allow that. At least not while there's a risk of pregnancy."

I had no idea what Ruki was talking about. Her claims were too bizarre, and her blowjob felt too good to process.

"Misjudge that, and you'll hurt Aika. Keep that in mind."

With a rapid handjob and tongue flicking my tip, I came straight into Ruki's mouth. She swallowed every drop without hesitation, sucking me dry like a baby craving milk.

"Will this shave 0.1 seconds off my sprint time too?"

With that joke, Ruki never brought up Aika again.

What did she see that I didn't?

What was I failing to see?

---

"You're late. Where were you all this time?"

When I returned to Sazanami-sou, Aika greeted me with cold dinner and a colder expression. I'd promised to be back in an hour or two, so I'd definitely overstayed.

"Don't worry. I kept my promise to Aika."

Ruki laughed it off, and Aika reluctantly accepted. Was the promise about not having penetrative sex? Or was there some other agreement between them?

"Ooh, curry! Looks delicious! Let's eat!"

"Hey! That's Dad's portion!"

Despite being in someone else's home, Ruki dug in without hesitation. Though, given that three plates were already set, Aika must have expected her to stay for dinner.

Ruki's father, a truck driver, was rarely home when she was awake. She usually ate alone. After inviting her to dinner once, it had somehow become a routine.

Meals were better with more people. Aika seemed happier, and for the middle school girls, it was the best way to spend time. And seeing them like this made me, as a guardian, happy too—though I'd never tell them that.
