Three Liters of Distilled Water: The Final Enema
Distilled water, 3000mL.
The label that caught her eye when she happened to turn her head.
By the time the image had burned itself into her mind and uneasy fantasies began to bloom, Han Munho continued in his calm, measured voice.
“For the finishing enema, we will be using a full three liters.”
“Three… liters….”
“A large quantity of material was inserted, and a great deal of it ruptured or broke apart deep inside. Therefore, this volume is necessary for the final cleansing enema. Your rectum has already been thoroughly dilated by thirty boiled eggs, so you should be able to accommodate it without difficulty.”
“…….”
Well, they had already pushed thirty boiled eggs inside her.
At this point, three liters of water might actually feel like a relief compared to what had come before.
Besides, having come this far, there was no turning back.
“If you have no objections, I will take your consent as given and proceed.”
“…Yes. It’s fine.”
With Eun Nanhee’s short, carefully spoken reply and a hesitant nod, the enema nozzle slid into her anus.
The valve opened. Cold water began to flow into her rectum under gravity.
Glug… glug, glug….
“Mmm…. Ngh, haa….”
She had thought she was used to the feeling of something entering her rear, to the sensation of an enema.
Yet once a certain amount of water had entered, her rectum began to swell and tighten from within.
The pressure rose from the entrance, then pushed outward, expanding her deeper passages. It was a feeling she had experienced countless times throughout the day, but one that still felt foreign and alarming after only a single day of exposure.
Gurgle… glorp….
“Haa, uht…. Hngh….”
The water kept flowing. It poured in until an unintentionally lewd sound slipped from Eun Nanhee’s lips.
A liter entered in moments. When breathing itself began to press against her tightening abdominal muscles, Han Munho’s hand gently compressed her belly.
Squeeze.
“Haa—hup?!”
“This step ensures the fluid reaches deep into the colon and large intestine. Please endure a little longer.”
“Y-yes… yeees….”
Any desire to resist had vanished long ago. All that remained was to follow Han Munho’s procedure to the end and endure.
Gurgle… glug, glug, glug….
“Haa, kku—hup…. Haaaa….”
Even as mounting pressure and pain threatened to overwhelm her, the steady stream continued to flood her rectum.
When the volume inside her surpassed two liters, Eun Nanhee felt herself approaching total saturation.
“Haa, w-wait… it’s full, it’s completely—”
“Breathe slowly, Miss Nanhee. Just a little more.”
“Hngh, kkuheu….”
At his words she stopped protesting and simply nodded. Her mind was a tangle, her stomach churned heavily, and her already-sealed anus strained to contain the relentless influx.
“Haa, huu… huuugh…!!”
When the volume finally approached three liters, she had no words left.
She breathed in shallow gasps, body folded low over the bed, sweat-soaked forehead pressed deep into the pillow.
Pop.
“Heut, kkeuheup…!! Haaaa….”
A short moan escaped the instant the nozzle was withdrawn. Her abdomen felt leaden. Her closed anus trembled with tiny, helpless vibrations.
The unmistakable sensation of every internal organ being completely filled with water settled heavily inside her.
And even then, a new wave of anxiety began to rise in her mind.
“T-teacher….”
“Yes, Miss Nanhee?”
“Just to be sure… do I have to hold it this time as well…?”
“Of course. I see you’ve grown familiar with the process.”
“Ah… aah….”
His decisive answer shattered the last fragile sliver of hope. Yet she could not afford to despair. Giving up would change nothing.
All the present Eun Nanhee could do was pray the time would pass as quickly as possible.
“Thirty minutes of retention are required for the solution to reach every part of the intestines.”
Even that small wish crumbled beneath his next words. At the thought of the half-hour still ahead, her mind burned hotter than ever.
Thirty minutes… ahead….
She had already endured thirty minutes with her colon packed full of boiled eggs. She had survived it once. All she had to do was endure again.
“Given the current expanded state of your rectum, even slight movement could cause leakage. Therefore, just as before, I will use my own instrument to seal your anus completely.”
“Hup….”
Even though she had experienced it once, the suggestion still left her stunned. Ignoring her sharp intake of breath, Han Munho calmly removed his pants, positioned himself, and stepped behind her.
Tap.
“…….”
The now-familiar weight nestled between her buttocks. Eun Nanhee froze, breath caught in her throat.
“Are you… are you really going to put it in again right now…?”
Spread.
“Uht, haa…!”
Instead of answering, Han Munho parted her anus and guided his cock forward. The sensitive opening, already slightly swollen from pressure, slowly yielded to his girth.
Squelch… schluurp!
“Haa, w-wait… ha, haaaa….”
The feeling of something hot and rigid sliding through the cold water made her thoughts blur. The insertion was slow, yet relentless.
Inside her rectum, the distilled water was forced even deeper by the pressure of his shaft.
Thrust… schluuuurp!
“Ah, aaaagh…!! Kkhaaaaaagh…!!”
Another tormented cry tore from her throat as her hips jerked involuntarily.
“Haa, n-no, teacher… I feel like I’m going to burst…”
“Not at all. It is perfectly sealed. You need only maintain this position for thirty minutes.”
“Haa, kku, huuuuup….”
Another thirty minutes in this state.
Her anus was plugged so tightly that not a single drop could escape, while three liters of water churned inside her rectum. Swallowing a pained whimper, Eun Nanhee barely managed to brace her hands against the floor and nod.
Thirty minutes… just thirty more minutes….
She closed her eyes, counting slowly in hopes that time would pass even a fraction faster.
Five minutes. Ten.
As time dragged on, the sensitivity within her body only sharpened. The heavy weight in her abdomen. The strange, constant sloshing of her insides.
She told herself she could barely hold on like this when—
Squelch….
“Hup, kkeuheu….”
Han Munho’s cock began to move with slow, deliberate undulations inside her. Her body reacted at once.
Slosh.
“Haa, kku—hngh….”
“Please remain still, Miss Nanhee. I am gently stimulating the interior to enhance the enema’s effectiveness.”
“Y-yes… heee….”
Believing once again that he must be correct, she obediently focused on the feeling of his cock moving inside her.
Then his next words brought a different kind of bewilderment.
“You mentioned you are university friends with our staff member. What is your major?”
“Eh…? My… major?”
“Yes. Since we have thirty minutes to wait, I thought a conversation might help pass the time.”
Far from bored, simply keeping her sanity intact while enduring was already pushing her to the limit. Yet because it was Han Munho speaking, she found herself nodding before she could resist.
“I’m… studying… sociology….”
“Then you must be in the same department as Jeonghye.”
“Yes… heeet….”
“It seems the exam period is approaching. Have you finished your midterms?”
“Th-they ended… this week….”
“You must have come to relieve some stress, then.”
“Yes…. Hu, hngh….”
Even as he continued the calm, polite questions, his cock never stopped moving inside her, stirring her belly with every slow thrust. Eun Nanhee answered through gritted teeth, barely holding on.
Why is he so… composed…?
He spoke as though the situation were perfectly ordinary. And because of his serene tone and handsome face, the depravity somehow began to feel almost natural.
No matter how painful or wrong it felt, hearing his calm voice made the entire ordeal seem like standard medical care.
“A university student must have had her share of romance, I imagine.”
“Ah, no… I haven’t… dated much….”
“Why not? Someone as lovely as you must have had plenty of suitors.”
“I was… too busy studying… and I wasn’t really interested in… that sort of thing….”
Squelch!
“Haa, kku—hup…!!”
The wet, filthy sound of friction. The heavy sloshing deep inside her rectum. As his thrusts grew gradually stronger, Eun Nanhee fought desperately to keep her fracturing mind from slipping away entirely.
