Happy Daily Life with the Parasitic Tentacle
“Then let’s go back in for now!”
“Huh..?”
“Nothing to be surprised about! It’s just going back in exactly the way it came out! Even if I wanted to chat more here, we don’t have time now!”
A thin tendril extending from the tentacle blob pointed to the right. I followed it with my gaze and spotted a red glow slowly approaching from near the castle walls.
“Ah...”
One, two, three, four... how many were there in total? Countless lights. My guess was the castle guards. They must have heard the explosion and come to investigate.
“Ugh...”
An obvious lie. It had just said moments ago that the one outside was a clone and it didn’t matter if it died.
“I’ll swallow it..!”
While I hesitated, the lights drew steadily closer. With no other choice, I finally opened my mouth wide and chose to swallow the tentacle.
“Urk...”
The slimy tentacle blob filled my mouth completely. The sensation alone was enough to make my eyes roll back and my body convulse in torment.
Gulp—
“Uwaaaack..!”
I couldn’t endure it. Clutching my throat, I doubled over, gasping and retching. The agony of my airway being crushed and my throat swelling went far beyond mere suffering—it was outright torture. Instinctively, my throat contracted in resistance, but it was pointless flailing.
“Ugh...”
Not only had I snuck out in the middle of the night, but I’d caused an explosion in a restricted zone. If the guards caught me, I’d be in serious trouble.
“Gasp... ugh...”
I dragged my trembling body and quietly made my way home.
The moment I opened the front door, my eyes met Barhen’s—he was sitting at the dining table, waiting.
“Airi... what on earth...”
Spotting my condition, Barhen jumped up in shock and hurried over. He fussed over me with excessive worry, as if he were my actual parent.
“Where have you been, and what were you...”
“M-Magic training was so fun, I got carried away... It was stronger than I thought, so I got hurt...”
“Sigh... even so...”
Barhen’s gaze traveled from my head down to my toes. I was covered head to toe in dirt, my knees were scraped, and my forearms were full of scratches. Worst of all was the state of my lower body, soaked in urine. I’d splashed water on the way back to mask the smell, but it was still suspicious enough to raise eyebrows.
“Airi, you are a court mage representing the palace. Don’t you realize that yet? You need to maintain your dignity.”
“Yes, Uncle... I’ll be more careful from now on.”
“Don’t act so recklessly like a child. It’s late—go up and rest.”
Earlier he’d been pushing me to become his sex slave, and now he was treating me like a proper court mage. If I’d known using magic would make this big a difference, I would’ve touched the Forbidden Book much sooner.
“Ugh...”
Mahel was lurking lecherously inside me, watching the whole scene. Was there really much difference between being a perverted old man’s sex slave or a parasitic tentacle’s pet? I let out a bitter chuckle at my pathetic life.
“...”
I headed to the bathroom without a word. I stripped off my dirt-caked robe and tossed it into the laundry basket. Now for the clothes underneath.
“Ugh...”
My hand froze mid-motion. The feeling of being watched made shame halt my actions.
“But...”
As Mahel said, ever since touching the Forbidden Book, I’d been in and out of the bathroom and bathed countless times. It had probably spied on everything—my naked body, my breasts, even my pussy—without me knowing. There was no need to feel shy now, but the humiliation didn’t just vanish.
“Kuhuk..! I’ll strip..!”
Hesitating too long triggered a gut-tearing abdominal pain. With tears pricking my eyes, I boldly stripped off my clothes.
The unwanted exclamation hit the moment I took off my blouse. Ignoring the creepy voice, I dropped my skirt.
“Ugh...”
Left in just my underwear, I timidly covered my chest and crotch, turning my head away. My face flushed unintentionally.
“I’ll strip, so... please be quiet.”
“Kuhuuuk!! Yes..! Sorry..!”
My stomach bubbled violently, unleashing unbearable abdominal pain. Clutching my lower belly, I doubled over, breaking out in cold sweat.
“Gasp... haa...”
Even after the pain subsided, my shocked body kept trembling. Just a week ago, my body had been perfectly fine—now it was utterly the parasitic tentacle’s plaything. An coercive master-servant relationship I couldn’t refuse no matter how much I wanted to. Powerless as I was, I had no choice but to submit.
“Eut...”
In the end, I took off my underwear. There were no other options anyway.
The irritating exclamation echoed in my head the instant I removed my bra covering my breasts. After slipping off my panties, a sleazy command followed.
“Why...”
“O-okay...”
Having felt the price of refusal firsthand, I obeyed without argument and stood before the full-length mirror on the bathroom wall. Staring at my naked body—something even I had rarely examined properly—my face burned red.
The repulsive exclamation rang out again, accompanied by Mahel’s giggling laughter echoing in my mind.
“D-don’t say that...”
I wanted to deny it, but Mahel was right—my body was perfection incarnate. Or more precisely, the body of 21-year-old mage Airi that I’d possessed was utterly flawless.

Double eyelids and plump cheeks accentuated her small, cute face, while long silver hair cascading to her waist highlighted her petite charm. Yet her well-developed figure exuded a completely different allure. Her large breasts were perfectly round, like overturned rice bowls, topped with pretty pink nipples untouched by pigmentation. From her slender neck, past her collarbones, a smooth waistline emerged without a hint of visible ribs. Below that, prominent birthing hips and plump, sturdy thighs demanded attention. At the center of her inverted triangle lines sat a straight, hairless slit of a pussy—not a single strand in sight. Porcelain-white skin, impeccable proportions without flaw. Standing still, she looked like a masterfully sculpted statue.
“Ugh...”
The unpleasant barrage of compliments continued. Standing naked before the full-length mirror, I gave an awkward smile and rubbed my arms. I desperately wanted to cover my chest or crotch with my hands, but I couldn’t act rashly.
“W-what...?”
“N-no, I haven’t.”
Caught off guard by the blunt question, I couldn’t hide my fluster. My eyes widened as I shook my head. Memories of my past life as a man still dominated my mind. The mere thought of tangling naked with another man and having sex made bile rise in my throat—it was utterly revolting.
“Eh...? Uk..!”
Before I could even retort, a stabbing pain pricked deep in my throat—the signal that the tentacle was about to emerge.
“Urk... mpgh...”
Clenching my mouth shut and resisting was futile. There was no stopping the tentacle as it writhed with intent.
“Uwaaaaaack!!”
In the end, I stretched my neck long and vomited up the purple tentacle blob. In the mirror, I saw the grotesque purple mass wriggling grotesquely as it surged out. My revulsion at the otherworldly being lasted only a moment—once fully expelled, Mahel scuttled onto my body like a cockroach.
“Eek..!”
It brushed past my breasts and slipped right between my legs. Sticking like panties, it rubbed against my triangular mound before suddenly trying to force its way inside the hole.
“Aa..! Eut..! Nooo..!”
The tentacle twitched against my pussy. The novel stimulation was utterly repulsive.
“Noo..!”
I clutched my crotch with both hands and bent forward. Desperate to pull it away, but the slimy, mucus-covered tentacle slipped through my fingers—my hands just flailed uselessly.
The tentacle’s slender tip wormed into my slit, prying open my entrance.
“Eek♥︎”
A chilling sensation. My unused, virgin hole—one I’d never even inserted a finger into—was being defiled by a tentacle. Just the slightest graze sent an eerie thrill down my spine.
