Happy Human Body Modification (2)
Pop— “Huuup...♥︎” Purrrr— As soon as the tentacle withdrew, an unbearable pressure welled up inside me. In the end, I squirted out slime with force, my body convulsing wildly.
[Oh dear... Can't you even endure this much?]
“Ugh...”
I wanted to hold it, but there was no way I could. It wasn't just a stomachache—it felt like my belly was about to burst.
[This won't do. We'll repeat it until you can manage. First, shall we push everything out of your intestines?]
“Ugh...? Guhhuuugh...!”
The tentacle membrane clinging to my lips writhed. From inside the membrane, a thick tentacle extended, piercing down my throat.
Gurgle— It didn't stop, stretching straight toward my anus.
“Guhb... Bruuugh...!”
It ignored the host's pain entirely. Thrusting blindly, it stabbed through my innards here and there.
Gurgle— “Guhk...!”
When it scraped past my colon, excruciating pain surged up, enough to make me black out.
Finally reaching my anus, the tentacle swelled my body. Like squeezing toothpaste cleanly from a tube, it scraped off the slime stuck to my insides and pushed it out.
Purrrr— “Guhbuuugh...!”
Slime dripped out of my anus in clumps, and soon the thick tentacle peeked out.
“Hoo... Kek...♥︎”
My body was skewered like a kebab again. It was maddening agony, but there was no escape.
[All clean now. Time to go back to where we started.]
“Ugh? Ugguuugh...!”
Faster than it had come down. The tentacle surged back up, reaching my mouth.
Gurgle gurgle— All in just three seconds.
“Guhheek...! Uuuk...!”
My asshole gaped open, and I retched. But there was no time to savor the afterpain—now a tentacle burrowed into my anus and reached my mouth.
“Oggooook...♥︎”
No respite as my body was pierced from both ends again. This time too, the tentacle sprayed a flood of slime as it slowly protruded from my anus.
I couldn't withstand the pressure and squirted forcefully, convulsing once more.
[Oh dear... At least try to hold it a little? If you keep reacting like this, the suffering will just drag on longer.]
“Uweek...”
But... but I caaan't... How am I supposed to hold back something impossible...
[Ailri, we'll push it out and inject again. Try to endure this time. We have infinite time, so I'll wait as long as it takes.]
“Ohook...♥︎”
The tentacle's malice-drenched torment. I wanted to go mad but couldn't, enduring enemas dozens, hundreds of times...
I had no idea how much time had passed. Thinking about time was pointless to begin with. One minute outside was a hundred years in here.
“Guhheek...! Heeeek...!”
My anus, enema'd hundreds of times, throbbed with raw soreness. The aphrodisiac-coated intestinal mucosa had swollen red long ago, losing its original shape.
Every time I forcibly clenched my sphincter, shivers ran through my whole body like goosebumps.
“Heeeek...♥︎”
Just clenching my anus made my pussy twitch, leaking juices. Swallowing normally, closing my mouth, even breathing—all came with faint pleasure.
It felt like my entire body had become a beast in heat...♥︎

Buried entirely in tentacles, my vision blocked. My sweat- and juice-soaked body convulsed in fear.
[Oh dear... Ailri, what if you still can't do it? It really won't end like this.]
“Huuweek... Hweek... I caaan't...♥︎”
The tentacle membrane peeled away, freeing communication, but I couldn't beg for mercy. Filled with awe toward the tentacle intent on wrecking my body, I asked,
“What... what do you even waant... why go this far...”
“Hmm~ Because it's fun? No deeper reason, so don't get the wrong idea.”
“Ah... Uu...”
Same voice as Mahel, same answer. Despite different speech and vibes, they were inseparably one at their core. I was the idiot for thinking we'd communicate.
Four thousand years sealed as a parasitic tentacle—that never changed.
“Hoo...♥︎”
Suddenly, a tentacle lightly rubbed my pussy, poking the hole.
“Let's stop with the ass for now. It's modified plenty anyway.”
“Uek... Uweek...”
“Now we'll remodel this.”
A thin tentacle slipped between the slit, wriggling like it was searching. Soon, its tip pressed right below my clitoris—the urethral opening.
“Ah... Nooo...♥︎”
I strained to resist, but it was futile thrashing. In an instant, the tentacle invaded my bladder.
“Hoook...”
“It's good that even a light touch makes your premature pussy climax... but you still haven't cum properly, so we'll remodel the urethra.”
“Y-Yes...?!”
“Because when Ailri cums, you cutely flutter your pussy and leak juices, right?”
Isn't that normal? What more was there to ruin here?
“A true woman must squirt a powerful fountain to climax properly. It appeals to men that you're a bitch who soaks her pussy hole like a urine-leaker.”
“Th-That's... no way...”
So vulgar...♥︎ Just imagining squirting every orgasm made my body ache. Now that imagination was about to become reality.
“Then let's begin the remodeling. Rebirth as a vulgar premature pussy.”
“Nooo...♥︎”
The eel-like thin tentacle slithered fully into my bladder.
“Oook... Hook...♥︎”
I felt the location of my bladder with crystal clarity, a place I'd never known before. The tentacle sucked up the urine inside and adhered to the inner wall.
“Eek... Keeweek... Wait nooo...♥︎”
My bladder contracted. Intense pressure like a fist clenching tight.
Then came a stinging pain like needle pricks.
[I've minimized the bladder's capacity. Shrunk it to about 100ml and fixed it so it won't expand taut. Now it'll leak out steadily once full.]
“Hek... Hweek...♥︎”
A normal woman's bladder holds 400-500ml. Not only shrunk to a fifth, it was remodeled to prevent further expansion.
“Huuut...♥︎”
Just lightly pressing my lower belly made my bladder contract, bringing unbearable urgency.
[Oh, forgot to mention—I remodeled your kidneys for faster urine production. Normal urine flows down the ureters at 1-2ml per minute, but yours is now about 10ml per minute.]
Meaning I'd need to pee every 10 minutes. On days I drank a lot, even sooner.
“Eut... Hook...♥︎”
Normally I'd release it forcefully, but the tentacle blocked my urethra.
[No worries. I'm absorbing the urine flowing out now. Relax and take the remodeling. Oh, and it might sting a bit from here.]
“Eek... Heeeek...♥︎ Kyaaahhhh!!”
I screamed involuntarily. From bladder to urethral tip—thin, sharp needles protruded from the tentacle's surface, piercing the sensitive flesh.
“Hah... Hah...”
[Oh dear... That painful? Hang in there anyway. I'm injecting aphrodisiac into your entire bladder and urethra for urination pleasure. When urine flows down, it'll feel as intense as a pussy-thrust.]
“Hook...♥︎ Nooo... Stoppp...♥︎”
Ignoring my desperate pleas, the tentacle injected heaps of aphrodisiac. As the needles withdrew, urgency surged again.
“Hweek...♥︎”
[Ailri, try holding it a bit. How much are you going to leak? Total pissy premature pussy bitch.]
“Huuweek...”
Coming from the one who made me this way, it rang hollow.
[No helping it. I'll drink it this time—hold next time?]
“I can't hold—”
[Oh dear... So weak already? Well, even if you don't want to, you'll hold. Guaranteed.]
What did that mean? The tentacle wriggled in my bladder, then slowly withdrew from the urethra.
[Ah, this hurts too?]
“Ok... Hook...♥︎”
Crackle crackle. It felt like electric sparks in my sensitive urethral walls. Stinging pain mixed with burning heat.
“Keehaaaak...!”
[You endured well. Did you know your clitoral root penetrates the urethra?]
“N-No ideaaa...♥︎”
[Oh dear... So ignorant about sex. To explain, the urethra and clitoris have nerve cells touching across one mucous membrane. I incised that to make a big protrusion, so urination will bring even stronger pleasure.]
In short, they'd extended my clitoral root into the urethra.
[Plus various big and small bumps, so it'll feel amazing.]
“Keeuuweek...♥︎”
[Urethra remodeling complete.]
Pop— “Hoek...!♥︎”
As the tentacle exited, my bladder contracted, spreading intense urgency.
“Hah... Hah...”
Holding back was impossible. Urine filled my bladder, pounding at the urethra.
“Kek...! Hook...! Nooo...”
My mind was filled only with the urge to release. I felt like I was turning into an idiot...♥︎
