The First Erection at Base 69

After accepting the offer to join the Mixed-Gender Unit Pilot Program, Kim Jaejun found himself in a surreal new environment—an all-female artillery battalion in Gyeonggi-do. That first dinner with his new peers was the beginning of a long, steamy challenge.

As beer flowed freely around the small dinner table, First Lieutenant Kim Somin leaned in to refill Jaejun’s cup. Her movements, whether intentional or not, exposed even more of her pale, full breasts, tightly hugged by a gray sports bra. Every tilt of her torso gave Jaejun a deeper look, testing his already fragile restraint.

Jaejun tried to suppress the erection swelling in his pants. He nodded mechanically at Somin’s words, silently drinking while his eyes darted down her neckline and traced the sensual curves above her leggings. His arousal throbbed painfully beneath the table, but he relied on years of discreet side-glances and strategic arm placement to both enjoy the view and hide his condition.

As the conversation shifted between Somin and Yoo Minju, Jaejun took advantage of the distraction to further admire his senior’s incredibly fit body. Then suddenly, Somin clapped her hands, her voice curious and casual.

“Oh! By the way—Minju, Jaejun—are either of you dating someone right now?”

Caught off guard, both officers answered no.

“Not at the moment.”

“Yeah… me neither,” Minju added, slightly blushing.

Somin raised a brow, intrigued.

“Why not? You’re both good-looking! Didn’t you have any flings at school?”

Jaejun chuckled nervously.

“We were busy with training, haha…”

But Somin didn’t seem convinced. She pressed on, teasing them gently about their lack of romantic or sexual experiences, her tone light but persistent.

Eventually, the teasing gave way to more standard “military life” advice—what a battery commander should know, how to survive battalion politics. Minju and Jaejun nodded through the lecture, though Jaejun’s mind was still fogged by lust.

The chicken dwindled, but his erection showed no signs of softening. It pulsed beneath his pants, painfully unrelieved. Then, seizing the chance, he feigned warmth and removed his combat jacket to drape it over his groin, successfully concealing the obscene bulge.

After nearly two hours of tension and beer-fueled restraint, Jaejun finally retreated to his third-floor room.

Once inside the bathroom, he dropped his jacket to the floor, then yanked down his pants and underwear in one swift motion.

Whoosh!! Throb! Throb! Throb!

His monstrous 26cm cock sprang free—veins bulging, precum glistening at the tip, twitching eagerly like it had a mind of its own. Jaejun wasted no time. The images of Senior Somin’s alluring body flooded his imagination—her full breasts, her tight sports bra, the mound between her legs that had burned itself into his mind.

He gripped his thick cock with both hands and started stroking.

Rub, rub, rub ❤️

The sound of flesh rubbing wetly echoed in the quiet bathroom. Jaejun’s breathing grew heavier. His mind played and replayed the scene of Somin’s marked, erotic mound—the peach-like curve etched with a vertical line of temptation. His balls tightened. His hips bucked.

“Ugh…”

The pleasure boiled over.

Splurt! Splurt! Splurt!

Hot white cum jetted from his swollen tip, spraying across the bathroom floor. His whole body tensed as he emptied himself, trembling from head to toe.

This was his first ejaculation since arriving at the women’s battalion.

The next morning, at 7:45 a.m., Jaejun stood beside Minju at the apartment entrance. Both were dressed in proper combat uniforms, waiting for Somin to lead them to the battalion HQ.

And then she appeared.

First Lieutenant Kim Somin, in black short leggings that hugged only half her thighs and a light windbreaker zipped halfway. She greeted them casually.

“Let’s go, guys.”

As they walked the short 100 meters to the guard post, Jaejun’s self-control was once again tested. Somin’s hips swayed in perfect rhythm, the snug leggings emphasizing her round, springy, apple-shaped buttocks. Every wiggle sent waves of lust crashing through him.

Wiggle ❤️ wiggle ❤️ wiggle ❤️

He tried to look away. He tried to distract himself.

“Donghaemul and Baekdusan…”
(the opening of the Korean national anthem)

It became his mental mantra to suppress the incoming erection. Luckily, he managed to resist. Barely.

Once they passed the guard post and entered the battalion building, Somin left Minju and Jaejun at the personnel office—her seductive figure disappearing up the hall, hips swaying all the while.

“I really want to touch it… just once…” Jaejun whispered internally, unable to shake the image.

Soon after, the personnel officer walked in—a middle-aged captain who greeted them kindly and prepared them for the transfer report ceremony, scheduled at 9:00 a.m. The formalities were brief and rehearsed. Then, with the officer leading, the two new lieutenants made their way to the battalion commander’s office.

Jaejun’s earlier lust was replaced by nerves. His hands were clammy. His mind raced.

Then came the knock.

Knock, knock, knock.
“Battalion commander, this is the personnel officer. May we come in?”
“Yes, come in.”

They stepped inside.

And Jaejun froze.

Behind the desk stood a woman with the air of a celebrity—a voluptuous, mature beauty who looked more like a Hwatu movie “madam” than a military officer. Her uniform could barely contain her large, round breasts, and her every movement exuded sensual authority.

This was Lieutenant Colonel Park Yumi, the commander of the XXX Artillery Battalion.

“Did they pick officers in this unit based on looks…?”

Minju. Somin. Now the battalion commander herself—all stunning, all magnetic. Jaejun’s thoughts bordered on disbelief.

The ceremony began.

“Salute the battalion commander.”

“Salute!”

“Reporting! Second Lieutenants Yoo Minju and Kim Jaejun have been ordered to transfer as of June xx, 2023. Reporting!”

Even as he stood at attention, Jaejun couldn’t help himself. His eyes drifted, practiced and subtle, to the battalion commander’s sensual body. Her curves, her voice, her aura—it was all overwhelming.

“She’s not just sexy—she’s downright lewd…”

As the official words passed back and forth, Jaejun silently thanked the one man who had made this all possible:

“Instructor… thank you. This place… this place is heaven.”

With a graceful smile, Lieutenant Colonel Park Yumi ended the meeting.

“...Alright, then. Once again, I welcome both second lieutenants to our battalion. Let’s arrange another time to talk more in depth.”

Thus concluded the 15-minute meeting between the battalion commander and the two new officers, Second Lieutenants Kim Jaejun and Yoo Minju.

As Jaejun stepped out of the battalion commander’s office, he felt an unexpected pang of regret. The gentle charisma and sensual presence of Lieutenant Colonel Park lingered in his chest like the warmth of sunlight on bare skin. His nerves from earlier had melted into fascination and desire.

He couldn’t help but hope for another chance to meet her again—soon.

The personnel officer who had escorted them to the office now led them back toward the personnel and intelligence departments to complete the remaining registration procedures. After signing off on paperwork about his apartment assignment and clearing security clearance with the intelligence office, Jaejun finally made his way to the 3rd Battery on the third floor.

On his way through the stairwells and corridors, female soldiers turned to look at him—surprised, curious, and maybe even intrigued. It wasn’t often they saw a male officer, especially one as tall and well-built as him.

Eventually, he reached the battery’s administrative office.

Knock knock.
“Hello… I’m Second Lieutenant Kim Jaejun, newly transferred in.”

From behind a monitor, a round, cute face peeked out. The woman smiled warmly.

“Oh my! You’re the new Fire Direction Officer, right? Nice to meet you! I’m Master Sergeant Go Suyeon, the 3rd Battery’s administrative supply officer.”

As she rose from her desk and walked toward him, Jaejun had to once again fight the urge to stare. Go Suyeon’s figure was breathtaking—full and curvy in all the right places. Her massive breasts, easily H-cups, strained subtly beneath her uniform, while her narrow waist gave way to wide, vase-like hips that seemed almost too generous for military fatigues to contain.

Even concealed under cloth, her body practically screamed “voluptuous.”

Jaejun used his now well-practiced side-glance technique to discreetly take her in. Then, offering a firm handshake, he introduced himself.

“Nice to meet you, Master Sergeant. I look forward to working with you.”

Her handshake was gentle and surprisingly soft—not at all what one might expect from a soldier. For a moment, Jaejun wanted to keep holding her hand, but she withdrew politely.

“The pleasure’s mine, Fire Direction Officer. With a man joining us, the office already feels brighter!”

With a playful smile, she motioned toward the room next door.

“You should greet the battery commander first. She’s in the next room.”

“Ah, yes. I’ll see you again soon.”

“Of course. See you later, Fire Direction Officer.”

Following her direction, Jaejun stepped next door and paused. He took a deep breath to settle his nerves.

Knock knock.
“This is Second Lieutenant Kim Jaejun, the new Fire Direction Officer. May I come in?”

“Yes, come in.”

The door creaked open. Inside was a smaller office than the battalion commander’s, but the woman seated at the desk commanded just as much presence.

She was Captain Lee Seona, commander of the 3rd Battery and Jaejun’s direct superior. And just like the others before her—Somin, Minju, Go Suyeon, and the battalion commander—her beauty was stunning. Sharp features, a graceful posture, and a cool confidence filled the room.

“Did they really assign people to this unit based on looks?” Jaejun wondered again.

The two exchanged pleasantries, and she asked a few standard questions related to the mixed-gender pilot operation. Then, suddenly, the conversation shifted.

“Jaejun, do you like working out?” she asked with an almost teasing tone.

“By working out, you mean...?”

“Weight training, I mean.”

“Ah! Yes! I’m not great at it, but I do like it.”

At that, Seona’s eyes lit up with genuine interest.

“Then after the kids finish PT, follow me. For now, read this mission manual.”

“Yes, ma’am.”

With that, Jaejun returned to the administrative office and sat beside Master Sergeant Go. As he read through the Fire Direction Officer’s Mission Manual, he kept sneaking glances at Suyeon’s buxom figure.

Through their chat, he learned that his predecessor was still on leave and wouldn’t be returning before her discharge. That left Jaejun free to settle in slowly.

As noon approached, Suyeon suggested they eat lunch.

“Fire Direction Officer, let’s go eat. The other officers will probably come straight to the dining hall from outside.”

“What about the battery commander?”

“She eats with the battalion commander.”

“Ah, I see…”

“Come on, let’s go! If we’re late, the kids will eat everything. Hahaha.”

Led like a younger brother by the warm and flirty Master Sergeant, Jaejun made his way to the dining hall.

The weather was heating up in late June, and the female soldiers had shed their jackets, leaving only black or digital T-shirts. Their figures—already impressive—were now practically outlined by the snug shirts.

As they stood in the serving line, Jaejun's eyes locked onto a particularly striking woman behind the counter. She had an innocent face, almost idol-like, paired with a lean yet busty figure that defied her slim build. Her chest—full, round, and impossible to ignore—strained softly against the dark fabric.

Ahead of him, Suyeon gestured to the girl.

“Hey, Hyunju. This is the new Fire Direction Officer. Give him lots of meat.”

The girl perked up with a bright smile.

“Yes! Fire Direction Officer, I’m Corporal Lee Hyunju, FDC Squad Leader. Nice to meet you!”

“Uh… yeah. Let’s work well together.”

Her cheerfulness brought Jaejun back to his senses. He managed a real smile before following Suyeon to their table.

Even during the meal, Jaejun remained hyper-aware of the attention on him. He was the only man in the dining hall, surrounded by beautiful women in snug shirts and casually flirty attitudes.

He finished eating faster than usual, trying not to gawk.

Back at the admin office, with about 15 minutes until the afternoon schedule, Captain Lee Seona reappeared at the doorway.

And for the first time, Jaejun saw her standing fully—and was stunned.

Her hips.

They were enormous, stretching the limits of her uniform pants. Curvy, round, and rivaling the exaggerated proportions of social media influencers, her backside gave new meaning to the term “hourglass figure.”

“She has the biggest hips I’ve ever seen...”

“Jaejun, let’s go introduce you to the battery officers now. Master Sergeant, please come too.”

Obeying her command, Jaejun followed his superior and Suyeon to the adjacent battery officers’ room. Inside, a group of NCOs lounged in chairs, chatting.

At Seona’s entrance, everyone turned their attention to the newcomers.

“Sorry to interrupt your break, but since we have a new member, let’s do introductions. This is Second Lieutenant Kim Jaejun, our new Fire Direction Officer.”

“Nice to meet you. I’m Kim Jaejun, the new Fire Direction Officer for the 3rd Battery. I look forward to working with you!”

A round of polite applause followed his greeting.

Then, Seona added:

“Let’s have a welcome dinner for our new Fire Direction Officer this Friday evening… Oh! Master Sergeant, the weeds have grown too much on the road in front of the main gate, so we’ll need to do some mowing this afternoon.”

Her words served as both a welcome and a reminder that this was still the military, after all.

Jaejun, now surrounded by an overwhelming number of beautiful, curvy women, was finally getting a taste of what life would be like at the XXX Artillery Battalion.

And so began his real military life… surrounded by temptation, tight uniforms, and far too many distractions.
