Thirty Boiled Eggs and a Cock
The warning at the start of the chapter had been clear. This session would include descriptions of food being inserted into a woman’s anus and the forced expansion of her rectum.
“Just two more, Miss Nanhee.”
“Doctor… please…”
Please stop.
I really can’t take any more.
Han Munho’s calm, professional voice offered no comfort at all. To Eun Nanhee it sounded as if he had said she still had nearly twenty left to endure.
Her rectum had already lost all elasticity, stretched to its absolute limit, and the pressure building inside her colon was reaching a breaking point.
The moment the next egg pressed against her, instinct made her flinch, her body desperately trying to block any further invasion. But—
Shhlup… shhluuup…
“Haaah…!! Haah, haaaah…!!”
The hole was already opened far too wide for any defense to remain.
The force pushing inward collided with the force trying to push outward. A fierce, uncompromising battle unfolded right at the entrance of her rectum.
Tap. Tap. Tap.
“Ughk, hu, hiiik?!”
Sluuuuurp!!
“Kyaah!! Kyaaaaaaaah!!”
The standoff ended in utter futility. All it took was Han Munho pressing his fingers against the wrinkled rim of her spread anus a few times, and the resistance crumbled.
The sudden release of tension let the egg surge deeper than expected. Eun Nanhee felt its smooth, heavy shape slide far inside her.
…And now, the final one.
“D-Doctor… I-I really… I feel like I’m going to die…”
“As I’ve told you repeatedly, you’ll be perfectly fine, Miss Nanhee.”
Tap.
“The body that has received my massages up to this point can easily handle this much.”
Squeeze.
“Aaaah……!! Haaaaah……!!!”
The instant her hole began to stretch again, it felt as though not just her anus but her entire body was being torn apart. Eun Nanhee shook her head frantically, a desperate no, but the gesture was meaningless.
“It’s all right. It’s perfectly safe. When it comes to this particular technique and years of experience, I am quite possibly the best in the world.”
His words were little more than a polite way of completely ignoring her reactions as he applied relentless, brutal pressure.
The thick, alien fullness sliding through her anus, the soft shape forcing her mucous membranes apart. Inside a rectum that already had no space left, the new object shoved everything else upward and brutally claimed its place.

Sluuuuurp!!
“Ughk…!! U-ugh, ughaaaaaaaaah…!!”
The moment the final egg slid completely inside, Eun Nanhee’s body collapsed forward as if every bone had turned to jelly.
“Uwaa, huuugh…. Huu, huk, haaaa…”
She looked on the verge of sobbing. Tears already brimmed in her eyes, and streaks of sweat and tears had dried on her flushed cheeks. Yet somehow she had endured. Her legs trembled violently, but she kept them locked, refusing to let them give out.
Still… I managed…
The strange sense of accomplishment that came with realizing she had taken all thirty eggs made her body react in an entirely different way.
Twitch… squeeze…
“Nngh?! Huu, haaah?!”
Her rectum was undeniably packed full of boiled eggs, yet her vagina began to throb and quiver with sharp, electric pleasure.
She tried to press her thighs together, but her knees shook so badly she couldn’t summon any strength. Hot, shaky breaths—impossible to tell if they were moans or simple panting—kept spilling from her lips.
At some point her nipples had stiffened into tight peaks. A warm trickle of fluid leaked between her thighs. And from deep in her belly, thick waves of pleasure kept rolling upward through her body.
Her hips bucked unconsciously. At that exact moment, Han Munho’s finger pushed even deeper into her anus, plugging her completely.
“Hngh, hu, haaaah…!! Gahuuuuuuuuh?!”
She couldn’t withstand that final stimulus. Eun Nanhee came hard, her whole body convulsing in climax.
“Well done. All thirty boiled eggs have been successfully inserted.”
By the time the sticky nectar from her pussy had begun to slide down her thighs, Han Munho quietly murmured the words while keeping her anus sealed with his finger.
It was a little while later before Eun Nanhee’s eyes opened again on the treatment bed.
Her body felt heavy, as if it had sunk into the mattress. Her belly was taut and bloated, like she was carrying a sack of stones inside. Even so, both her vagina and anus continued to twitch with hypersensitivity, and the heavy, foreign weight deep in her rectum remained vividly present.
“Is it… over?”
Her voice was barely a whisper.
Han Munho gave a small nod at the exhausted words she managed to push out between labored breaths.
“Yes. The insertion phase is complete.”
“Hngh, huuuu…”
The insertion… is over.
At those words, the tension drained from her jaw. Eun Nanhee let out a long, shaky exhale.
The boiled eggs still filled her rectum and colon to bursting, but at least nothing more would be forced inside her. That knowledge alone sent a wave of relief washing through her entire body.
Yet the moment she began to relax, his next sentence made her tense all over again.
“We will now maintain this state for a set period of time. This is the final stage of Dilation Training.”
“…Pardon?”
Maintain this state.
For Eun Nanhee, who wanted nothing more than to expel the eggs packed inside her as quickly as possible, the words were bewildering. Han Munho continued as if it were the most natural thing in the world.
“Your rectum and anus are currently expanded to their maximum capacity. If we allow them to contract immediately, the tissue could reflexively tighten and suffer damage. Therefore, an adaptation period is necessary.”
Slide.
“Uht, haaaa…”
He spoke while gently rubbing her swollen belly in smooth circles. The sensation was strange and invasive, but she had no mental room left to dwell on it. The idea of having to endure even longer was far more alarming.
“H-How long do I have to hold it…?”
“It won’t take long.”
“Then… maybe five minutes…?”
“Thirty minutes should be sufficient.”
“………”
Her mind went completely blank. Eun Nanhee’s face twisted in horror.
“Thirty… minutes…”
“It’s not as long as it sounds. If you simply relax your mind, Miss Nanhee, it’s a perfectly manageable length of time.”
…No matter how she looked at it, thirty minutes sounded utterly impossible.
Even now the eggs inside her were churning and shifting, as if trying to force their way out at any second. Was it truly possible to endure for a full half hour?
Squeeze.
“Uht, huuuu…”
Completely disregarding her obvious distress, Han Munho pushed his plugging finger a little deeper into her anus. At the same time, his other hand moved to his waist.
Click. Click…
The slow sound of a belt being unbuckled echoed through the massage room.
“Of course, I understand that suddenly asking you to endure thirty minutes like this may seem harsh.”
“Y-Yes… exactly… thirty minutes is really too much…”
“Your anal sphincter has already become far too relaxed. It would be difficult to keep it sealed with just my fingers. Since the opening is now significantly wider than when we began, we’ll need something thicker to plug it properly.”
“I-Is that so…?”
“Yes. Unfortunately, I don’t have the ideal tool on hand right now, so I will substitute with my own cock.”
“……Pardon?”
It took her several long seconds to process what she had just heard. The sheer shamelessness of his explanation left her stunned.
“It is an object that is clearly thicker than a finger and fits the current dimensions of your anus perfectly, Miss Nanhee. The temperature is similar to your body heat, and the thicker ridge in the middle will prevent it from slipping out easily.”
“B-But…”
“This is purely therapeutic. There is no personal desire involved. I will now proceed.”
Without waiting for further protest, Han Munho slowly pressed the head of his penis against her anus.
Tap.
“Uht, haah?!”
The moment the warm, soft-yet-strangely-firm glans brushed across her wrinkled rim, Eun Nanhee’s body jerked reflexively.
“Haa, ha, haa…”
“Keep your breathing steady, Miss Nanhee.”
“Y-Yes…”
She could already feel something else trying to push into her overstuffed belly. Her rectum tightened, her vagina clenched in reflex, and more fluid leaked helplessly from her.
Every time something entered her hypersensitive anus, a moan slipped out before she could stop it. Even so, Han Munho’s glans continued to spread her slowly open until, with a short, wet sound, it lodged firmly inside her.
Pop!
“Ump, hngh?!”
Just the glans, exactly as he had said.
She didn’t know whether to feel relieved that he hadn’t lied, or horrified that any part of his cock was now inside her ass. Either way, there was only one thing she could do.
She tried to ignore the foreign object pressing against the entrance of her rectum and simply endure the time.
No matter how uncomfortable or mortifying it felt, she only had to last thirty minutes. With that thought, Eun Nanhee struggled to hold her position.
Squeeze.
“Uht, huuup…”
Yet the mere knowledge that another person’s cock was inside her body refused to let the embarrassment fade. Especially for a girl who had never even had a boyfriend, let alone any sexual experience with men.
