Phantom Thief Lupin, Infiltrating! (3)

One of the essential elements to observe during infiltration is to silence (消音) sounds so they don’t leak out.

While surveillance cameras or reconnaissance drones that move without anomaly at regular intervals can be evaded by understanding their patterns or temporarily neutralized, people…monsters are different.

If even a faint vibration was detected, individuals never came; they always moved in groups of two or more.

Even though there was equipment stolen from Klaus’s technology, it was still a wonder how they hadn’t been caught until now. Compared to a noble’s mansion, which was technically and humanly strict, the Tax Evader Containment Facility had such lax security that I thought I could easily escape.

…Until I was caught by something that was neither a machine nor a monster.

….

‘Th-there are monsters like this too?!’

A semi-solid monster, like a bouncy pink jelly, charged at me like Huggy Wuggy.

It charged with fierce momentum, knocked me, who was lying prone, over, then squirmed and slowly began to consume my body…

The sticky slime, like snail mucus, soaked my Phantom Thief outfit and rose up to my chest, making me feel a bit suffocated, but fortunately, it didn’t reach my face, so I wasn’t choked.

Shurururuk Shureuk..

It felt less like being eaten and more like being pinned down…Inside the translucent slime, dark pink tentacles slowly began to coil around my feet and fingertips. At that point, a sensation I had never felt before made me instinctively try to pull my body back, but…

Cheolpeok! Cheolpeok!!

“Let go…let go…!”

I forcefully struck the slime mass with my two free arms, but despite its soft and pliable appearance, it didn’t break easily.

Was my strength weak, or was this slime-like monster excessively hard? As the clearly visible tentacles in the slime climbed up my thighs, another tentacle, shaped like a morning glory, shot out from the monster’s rear.

“M-my mask…Hup?! Heueup?!”

─Cheolpeok!!

Immediately after it ripped off my mask with an extra tentacle, I tried to pull off the tentacle that was tightly gripping my face like a facehugger, leaving no breathing hole, but it stuck fast to my face and didn’t budge.

‘I-I can’t breathe…!”

I should have realized that this was a place where tax evaders were treated as less than livestock, and thus could easily be killed. But due to the tight schedule, I acted too rashly without preparation.

What would happen next? Would my bones be crushed and I’d die like this, or was this a monster that melted and consumed me while I suffocated?

Whatever it was, the thought of dying miserably in an empty ventilation duct intensified my struggles, but it was useless; I couldn’t pull off the gurgling tentacle that seemed to be trying to spit something out.

…Gurgling?

Pushiiiii─

“Heubeup!! Eueueup?!”

‘It’s sweet…Could it be…?’

Pushik─Pushuuuk─Puk, Puk

The substance I felt from the hand holding the stem was aphrodisiac gas. What was spread around the passage wasn’t aphrodisiac residue, but this monster’s slime.

Thanks to the amount that was sprayed out, more than enough to be injected into my body, the part gripping my face slightly opened, allowing me to breathe, but I had ended up inhaling something I shouldn’t have.

And a lot of it…

A lot…

Pushuk─Pushuuuk..

Puk─Puk─Pushyush..

“Heum…Heu, Heuneueu…”

‘I…I shouldn’t drink it…’

『Aphrodisiac Poisoning (Minor) status is added.』

『Body sensitivity dramatically increases. Estrus probability increases based on the amount injected into the body.』

『Sensitive Nipples LV1 is activated.』

『These are small, cute nipples that are not yet developed. Pleasure felt from nipple caressing increases.』

『Nipple Development Progress: 10/100』

The voice echoed in my head once again.

Not only was I suffering from aphrodisiac poisoning, but the “Sensitive Nipples” status, which had popped up last time, slowly increased every time the tentacles that had entered my clothes caressed my nipples.

『17..20…26…』

I had to escape, and I knew in my head that I shouldn’t be feeling this, but…

My mind felt like it was going to stop just from my small, cute nipples-which I had only seen in a mirror, not even my crotch-being touched.

“Paha…Haa…Haa…F-fuck…”

‘I have to pull myself together…I can’t stop thinking…!’

I must resist the pleasure.

I must not succumb to pleasure.

This is not a situation to pursue only pleasure.

The moment I stop thinking, it’s over. Not being able to move is one problem, but if my reason, dulled by the sweet floral scent, snaps and I surrender my body to pleasure, I’ll be discovered and caught in an instant.

My wire gun was tied off for a rope during my escape, so I couldn’t use it. If I had known this would happen, I would have brought at least a self-defense knife…

Jjuup Jjuup.

“Huaat?! D-don’t suck…!”

Just like the one that covered my face, a small tentacle of the same shape firmly bit onto my two fruits and moved.

A vulgar slurping sound was heard, and a high-pitched voice, one I had never uttered before, escaped me at the sensation of my nipples being gently licked.

It was Lee Seri’s natural female tone, not the lowered voice she used to pretend to be a man. Even covering her mouth with both hands couldn’t stop the moans from bursting out.

The flower-shaped tentacle, as if demanding breast milk, made louder “jjuwap-jjuwap” sounds and clung tightly to my breasts, which produced nothing, refusing to let go.

…

“Hua…Neut…♥”

How much time had passed? By the time the development progress reached around 25, my rapid breathing grew even more intense.

I didn’t want to feel it, but my hands, which had been covering my mouth to endure the forced surge of climax, tightly gripped the elusive slime.

I don’t want to feel this from a monster like this.

In a situation where every second counted for stealing and escaping, I didn’t have time to be tied up like this, but…

I don’t want to come…! A man coming from something like nipples, that’s…

“Haang♥ Aht♥ Heua…There…Please, st-stooop♥♥♥”

My lewd body, trembling uncontrollably, was trapped in the loosely spread slime.

My body, steeped in pleasure that felt several times more intense than ejaculation, went limp as if paralyzed, and lukewarm vaginal fluid burst from my closed petals, dampening my pants.

『Climax confirmed. Corruption Desire LV1 experience increases.』

『Aphrodisiac Poisoning (Minor) has increased to Aphrodisiac Poisoning (Medium).』

『Body sensitivity dramatically increases. Estrus probability increases based on the amount injected into the body.』

『Nipple Development Progress: 92/100』

“Hua, Heueueu…”

The climax experienced in a woman’s body lingered longer than expected.

It wasn’t my vanished dick being rubbed, nor was I being fucked like in the truck.

Although I had become sensitive due to the aphrodisiac, to climax just from nipple caressing…As a man, it was something I would never allow.

However.

However…while I felt shame, the thought that it felt incredibly good also crossed my mind.

I couldn’t forgive myself for being so helplessly subjected, so my mind didn’t completely shut down.

Kkul-leok…Kkul-leok…

‘It…it got bigger…?’

One way to acquire magical power: . The monster seemed to have absorbed the magical power-laden vaginal fluid that had been released during my climax, as it gradually swelled from a size that could pass through the duct until it eventually became so enormous that it completely filled the passage.

Not only was my only escape route blocked, but I was also in trouble, pinned under this increasingly heavy creature. The slime, which had covered my upper body, slowly crept up, eventually rising enough to envelop my entire body.

“Kkup…Oop…!”

‘It’s painful…’

『Pain Resistance LV1 is activated.』

『Pain Resistance LV1 is activated.』

『Pain Resistance LV1 is activated.』

『Robust Physique has been added.』

『Linked with Pain Resistance. Overall endurance and defense increase.

Even if that activates, I’m still suffocating…!

The crushing pain was slightly lessened, which was better than nothing, but I couldn’t do anything about my breathing. Since I’m human, it’s natural to die if I don’t breathe, so it seems there’s no suffocation resistance, as it wasn’t added.

Even struggling, my weak strength offered no way to overcome the crisis. Just as I thought I might die like this, I heard men’s voices from the floor below-that is, the staff breakroom.

─See, I told you! I wasn’t mistaken, was I?!

─It is unusually strange today. I’ll go check it out, so don’t touch the cards.

Kkiik…

Swaaaaaaa!!!!

“Uwak!! What! What the f-f-f-f-f-f-f-fuck…!”

“Waaaaaak─!! Why did this bastard get so big?! Did it go to a Magic Tank or something?!”

Like water draining away when a drain cover is opened, the pink slime monster swirled down the wide-open ventilation duct as if being sucked away.

Below, it seemed to have become a complete pandemonium. Men’s screams mixed together from the breakroom, which was half-filled with aphrodisiac slime.

“Everyone run! The Wall Roper is rampaging!!”

“What the hell did it eat to not listen…Oohk, Ooohk?!”

…It was a terrible sound. I hadn’t seen it directly, but thinking that I had made similar sounds when I was being caressed, it certainly wasn’t a spectacle to show others.

“I-I’m alive…”

Anyway…what do I do now?

The lingering sensation had subsided, but my body was steeped in aphrodisiac, and my wire gun’s trigger was broken from being crushed by the weight, making it impossible to fire.

The monster’s rampage would soon trigger an emergency, and they would come to inspect the ventilation duct where I was to find out why it rampaged.

Normally, I wouldn’t even think about this and would have just run away. My usable tools were broken, and my body wasn’t in a normal state, so no way to safely rob the safe and get out came to mind.

I wished I could at least disguise myself, but with a body smaller than when I was a man, there were no monsters I could impersonate. A succubus would have to expose her face, so I’d be caught by any monster who had already seen me.

‘….Let’s go.’

Going back won’t change the future.

I only had one day left. If I couldn’t pay the human rights fee, I would come through the main gate, not the ventilation duct, and as a slave.

Live as a flesh toilet and an aphrodisiac test subject? Never… Faced with a deadly dilemma where I had no choice, I moved forward.

My goal wasn’t money, but the Magic Tank. If I could just steal a few bottles, which held high value even in small amounts…I could go back to normal.

…

Perhaps it was quiet because they were busy stopping the monster rampaging in the breakroom, but no sound could be heard from Guld’s warehouse.

Recalling the daily life at the cafe with Miwol, I finally reached the ventilation duct above the warehouse and peered through the gap.

There were boxes made of banknotes…and an armor decorated with jewels, slightly different from the one by the entrance, on display. And…

‘I found it…’

Right next to the rows of banknotes, inside test tubes held in an iron box, was a blue liquid symbolizing mana.

Judging by its deep blue color, like the ocean, unlike the light sky blue freshly extracted from people seen below, it was clearly a high-quality item.

‘There doesn’t seem to be any security…and no laser sensors. Let’s go down.’

Could it be that there really were no devices installed? I grabbed the narrow gap and pulled, easily lifting the ventilation duct cover. I set it aside and landed on the warehouse floor, yet nothing happened.

No matter how arrogant he was, I thought there might be something in the Warden’s warehouse…but there was nothing.

No arrows flew, no toxic gas emerged, and there wasn’t even a single surveillance camera.

‘…Well, that’s good for me.’

I put about five test tubes filled with shimmering mana into my pocket, then bunched up a pile of banknotes to create a foothold, preparing to climb up.

To think I have to do this because I’ve shrunk…I want to hide here until the situation calms down…but there’s a hook on the side I came in from, so let’s hurry back····················

“…….”

Wait.

That armor…it seemed to move a little.

“I thought we were supposed to meet in the …I didn’t expect to meet you in a place like this.”

“Guld-eueueueu?!”

“Na-hahahahaha!! Good! Very good! You’re the one who made the Wall Roper rampage and grow, aren’t you?”

“Aueueueueu?!”

With a familiar laugh, the staff held by the armor pointed at me, and a purple electric shock was discharged, hitting my body directly.

『Robust Physique is activated.』

『Pain Resistance LV1 → LV2 has increased.』

“Ahak, Hek, St-stooooop─”

“Your mana, it might be no different from a Magical Girl’s. I never dreamed such a big catch would be hooked! Na-hahahahaha!!”

“Haek…Heugya…Ha, Hea…”

“Oh-ho…To not even faint after being zapped this much. Were you really a Magical Girl? A Phantom Thief who’s also a Magical Girl. Quite a good setup, wouldn’t you say!”

No, I’m not…

I’m not a Magical Girl…

As he removed his helmet, grape-colored skin and a bushy beard were revealed. Seven Stars, Warden Gould, showed himself and aimed his staff at me again.

“Ahi, ya…Ahi, rahoo…Magical Girl, nooo…”

“It seems your tongue can’t even roll properly now…When you open your eyes next, let’s meet with a smile.”

The purplish gem at the tip of Guld’s staff began to glow, firing a powerful purple electric shock at me.

Pajijijijik─!!
