Desperate Urination and the Emergency Summons
I considered just pushing aside the thin, slippery tentacle and peeing anyway. It should have been perfectly possible. But the strict order not to touch my pussy flashed through my mind, making me hesitate.
"M-Master...!"
I called out to Mahel a bit louder, and my stomach writhed as a response echoed inside me.
[What? I just told you not to wake me up.]
"I-It's just... I really have to pee..."
[So?]
"P-Pardon...?"
[I've been thinking, and humans don't just have three kinds of 'desires.' Excretion could be a good energy source too.]
"Th-That's..."
[I'll limit excretion to once a day. Hold it in as best you can.]
Once a day...? There was no way that was possible.
"M-Master... please... it's already so hard right now..."
[Then do you want to use today's chance now? If you go now, no excretion until midnight! How about it?]
"Ugh... ugh... y-yes..."
[Good.]
I didn't want to think about what came after. My lower belly had already gone past aching into hammer-blow pain.
"Hurry... please..."
My legs trembled as I begged, but the wicked tentacle's commands didn't end.
[Beg a little more vulgarly and pathetically! Realize you're not human—you're a pet!]
"Ugh... khk..."
[Tsk! If not, no peeing?]
Not content with stealing my freedom to excrete, it demanded I throw away all my pride too. I wanted to resist, but I was at my limit.
"Kkhk...! Airi has to pee so bad it hurts...! It would be so great if Master would graciously let her go...!"
[Mmm~ It was pretty clumsy since it's your first time, but good enough. I'll let you go, so head outside?]
"Y-Yes...?"
[It feels like it's missing some thrill! Squat naked in the yard!]
"Hic... y-yes...!"
The lowly tentacle's torment continued, but I had no will to resist. With my bladder feeling like it would burst, I burst out of the bathroom and stripped off my clothes in a panic.
"Ah..."
There was a wall, but it was only about a meter high—low enough for anyone to peek easily. It was early enough that few people were around, but anxiety flushed my face red as I squatted down.
[Now~ Spread your legs wide and show your pussy! Hands behind your head! That's the excretion pose!]
"Yes, Master...!"
I spread my legs wide and clasped my hands behind my head, just as the tentacle ordered. It was a vulgar pose no sane woman would ever strike.
[Puhaha! Good girl~ Now I'll let you go~]
"Yes...!"
The moment of excretion I'd been waiting for. I assumed the tentacle panties would vanish, but that was naive.
A thin tentacle tendril extended from inside the panties.
"Euggh♥︎"
The tendril scraped along my slit, adjusting position before burrowing into my urethra. The unfamiliar sensation jolted me upright, leaving me gasping.
"Hah... haaaahk...♥︎"
Pain? Pleasure? I couldn't tell. The tendril delved deep into my urethra and reached my bladder... and then—
Slurrrp slurrrp—
"Kkhheek...!♥︎"
It felt like it was sucking my bladder dry through a straw. The pain in my lower belly gradually faded, and the urge to pee vanished.
[You can't just waste precious pee like that! It's all going to be my nutrients!]
"Khk... ugh... h-heek♥︎"
Once the pee absorption was done, the tentacle extended a thin tendril outside the panties. Dribble dribble—
"Aaah..."
The transparent liquid—now fully robbed of nutrients—arced out in a parabola. My face burned with shame as I stared blankly at the distant mountains.

"Hoo... ♥"
Absorption and expulsion complete, the tentacle returned to its place. My vulgar hole twitched in aftershocks as my legs gave out—I couldn't stand.
"Kkuuugh..."
I never wanted to go through that dizzying stimulation again. But my feelings didn't matter.
[This is how we'll handle urination from now on, so get used to it. You won't ever take off your panties without my permission in your lifetime.]
"Ugh... kkhk..."
[Answer me?]
"Hahk♥︎ Yes, Master...!"
Any sloppy response earned instant punishment. Stomach cramps wracked me as the tentacles on my breasts and pussy thrashed wildly. An itch like thousands of ants crawling surged up.
"Kkhaak...!"
My hand instinctively reached down.
"Hik♥︎ Hiik♥︎"
I wanted to rip off the tentacle covering my pussy. Knowing I couldn't, I clenched my fist in midair and stopped.
[Behave, and it won't torment you.]
"Ohook... kkhk... ♥"
Enduring unwanted pussy stimulation, I realized I was just a hole-bearing bitch... ♥ It felt like an unfamiliar sexual desire was creeping up on me.
I left the house and headed straight for the Kingdom Library. Mahel was currently in hibernation. The tentacles covering my body writhed ceaselessly, spreading faint pleasure.
"Hoo... eek...♥︎"
With my flushed red face, I took slow steps. Hunched over with bent knees, twisting my body—anyone who saw me might get the wrong idea.
"Kkhoook... eek..."
I barely made it to the Kingdom Library. I wanted to dive into magic studies as usual, but it was pointless now. Magic wasn't something you could grow through effort alone. My talentless body could only borrow power from the parasitic tentacle Mahel. Better to focus on ice magic as Mahel suggested than learn useless spells.
"Haaang...♥︎"
Suddenly, a lewd moan slipped from my lips. I whipped around with wide rabbit eyes, checking if anyone heard. Luckily, no one was nearby.
"Heung...♥︎ Haheut...♥︎"
Step by step... Every movement rubbed my thighs against the slippery tentacles, spreading faint pleasure. The agonizing tickle—like a soft feather brushing sensitive spots—repeated endlessly.
"N-No more... haahk...♥︎"
Even a woman with frigidity would turn into a pleasure-drunk bitch after hours of this.
"Kkhk... ha... haeung...♥︎"
I headed to my secluded corner of the empty library. Flanked by towering bookshelves that reached the ceiling, it was perfect for hiding. At the corner where shelves intersected, there was a round spot on the dust-free floor—my fixed seat where I always squatted with my butt planted.
"Eung...♥︎ Haa...♥︎"
Now, even a slight hip twitch rubbed my pussy, sending pleasant jolts. My hazy mind filled with unfamiliar sexual desire.
"Eugghk...♥︎"
I wanted to masturbate. Scratch my pussy furiously. Plunge my fingers in and satisfy the urge. My head swam with sexual impulses I'd never felt before.
"No... nooo..."
I snapped out of my daze, shaking my head frantically to regain sanity. Disgusted with my perverted self, I squeezed my eyes shut. I absolutely didn't want to do what the tentacle monster wanted.
"Hoo... hoo..."
After deep breaths, I reached for the tower of books beside me.
"It has to be here somewhere... Ah, found it..."
A fairy tale book I'd glanced at out of curiosity and lost interest in. It featured senior magic beasts that once nearly wiped out humanity, including a story related to the parasitic tentacle 'Mahel.'
"Eum..."
I opened it, but there was no useful info. How Mahel was sealed, its connection to the Forbidden Book, its abilities—nothing.
"Useless..."
It was just a kids' scary story. The exaggerated depictions of parasitic tentacles felt far from reality.
I'd gained nothing, so I closed the book. Better to learn one more spell in this time.
"Airi."
"Ah, Senior Bessy..."
Bessy, who always sought me out, gave a bright eye smile. Her timid little hand wave was adorable.
"Hoot...♥︎"
Of all the worst timings, the worst encounter. The tentacles clinging thick like toothbrush bristles between my legs rubbed my pussy without cease. Even though I hadn't committed a crime, I flushed in panic.
"Ah... Senior Bessy, is something wrong?"
I changed the subject to hide my fluster. Even without that, Bessy seemed oddly different. Like me, the library ghost, she was a totem guarding the palace interior. But the hand that should hold a book gripped a magic staff, and beneath her black robe, her waist was lined with potions. She looked ready for an expedition far away.
"Airi, you haven't heard the news?"
"No...?"
"An emergency summons has been issued. All court mages have gathered."
"Ah... really...?"
A summons? As the lowest-ranking failure among court mages, it was news to me.
