Chapter 167: Be Cautious of Side Effects with New Products (3)
"Alright... then..."
Slurp.
With the unique sweet scent of a homunculus's flesh lingering in the air, I began to lick her tightly closed pussy, prying it open with my tongue.
Her soft, pliable breasts moved under my touch, shifting with my fingers. While the smooth, rounded mounds were delightful, the perkiness of her nipples provided a much more satisfying sensation to my hands.
It felt almost like the cherry topping on a whipped cream cake—a detail that might seem unnecessary but, once missing, leaves you craving for it.
"...Hmm?"
But something felt off.
Normally, when licking a woman's pussy, the sticky, slightly tangy taste of the inner mucous membranes should register on the tip of my tongue. Yet all I tasted was the faint sweetness of skin, as if I were licking a folded section of flesh rather than anything more intimate.
'What the hell is this?'
I knew a homunculus's body structure differed from other species, but even with the previous ones I'd licked, there was a distinct sweetness accompanied by the feeling of mucous membranes. But now, licking the folds of No. 3's slit felt oddly unsatisfying.
"...Hmm?"
Curious, I slid a finger into the split, but instead of feeling soft inner walls, all I found was a rounded, folded structure of skin resembling nothing more than shallow folds.
There wasn't even any depth to speak of; my finger barely got two joints in before hitting flesh, unable to go any further.
"Wait... what?"
"Since No. 3's body was designed with a set structure, she doesn't have much flexibility to mutate or transform her body. Even with the same drug, her changes would be limited to surface appearances..."
"This is a scam!"
I glared at Frederica in anger, who immediately flinched and instinctively covered her ass. Seeing her reaction, I could only sigh and shift my target back to her instead.
"Fine, just this once, I'll let it go."
"...Huh?"
"Normally, you don't meet my standards, but under the circumstances..."
"Wahhh! Don't come near me like that while you're hard! And why is it getting even bigger?!"
As Frederica finally snapped out of it and tried to run away, I grabbed for her—
Knock knock knock.
"Is something wrong? The guests are complaining about the noise..."
The door suddenly opened, and a horned helmet poked through, glancing inside.
"...Ban?"
"Huh? Oh, Erin!"
I dropped Frederica, who had been halfway undressed, and immediately redirected my attention to Erin.
"Thank goodness. If I'd been any slower, I might've actually had to use Frederica."
"What... exactly is going on here?"
Erin looked around the room, then stepped in, closing the door firmly behind her, locking us all inside. It was almost as if she was anticipating that I'd try to bolt.
"Is this your doing?"
I felt a sharp tension, almost like a stinging slap against my cheek, but I figured it was just my imagination.
"It's nothing serious. By the way, can I borrow your ass for a moment?"
Without hesitation, I casually lifted her skirt and stroked her ass. As expected, Frederica's immature, underdeveloped body couldn't compare to Erin's firm and smooth curves.
"Alright, let's start by taking off the helmet. Hiding such a pretty face is such a waste."
Lifting her faceguard, I expected to see her usual blue, flame-like eyes, but instead, her gaze burned with a red, smoldering intensity. Every nerve in my body screamed for me to back away, but with my dick taking control of my brain, instincts were meaningless compared to the urge to shove it into the woman before me.
"Was it... you?"
"Yep. I just got done with Delphine, but she passed out, so now I'm short. Erin, can I—ugh!!"
A loud crack came from my neck as a fierce impact slammed into me, and my consciousness faded.
---
"Ugh... urgh..."
A sharp pain in my neck woke me up. The first thing I saw was Erin leaning over me, her expression filled with worry.
'Why is Erin here?'
"Are you okay?"
For some reason, my jaw hurt.
I tried circulating my mana to check my condition, but strangely, my mana circuits wouldn't respond. Pro bing my jaw with my tongue, I felt a sharp, stabbing pain—it seemed like the bone had cracked.
"My jaw hurts... and so does my neck."
"Of course it does. You got headbutted by a half-ogre's brute strength."
For some reason, Frederica, now wearing a completely different outfit that covered her body thoroughly, appeared before me. Next to her was Delphine, groaning as if her back hurt while seated in a chair, fiddling with something on my body.
"What the hell happened? Why does my body hurt so much...?"
"You seriously don't remember after all that chaos?"
Frederica, her face bright red with anger, glared at me. Judging by her reaction, I must have caused some trouble, but I couldn't fully recall why she was so worked up.
"You don't remember swelling that thing up to the size of an arm and rubbing it against my ass? Or groping No. 3's body until you bruised her chest and crotch? And then you had the audacity to swing that thing around as you came at me again?"
Forcing my hazy brain to process, I tried to piece together the blurry fragments of memory. I remembered tasting No. 3's plump pussy lips, getting enraged over her shallow, fake hole, and almost completely stripping Frederica's underwear while grinding against her. And then...
"Ughhh!"
'What the hell did I do to that 300-year-old geezer?!'
Even if her body was currently female, her true self was still that old bastard!
"I... I actually got hard over Frederica?!"
"What kind of reaction is that?! If anyone should be angry, it's me!"
"No, no, this isn't about Frederica—it's about me! I'm mad at myself! How could I get hard over Frederic Endymion?!"
Because I'd been calling her Frederica all this time, I must've fooled myself into forgetting who she really was. How in the world did I lose control and get hard over an old man?!
Even if my dick was controlling my brain... No! Especially because my dick was in charge, I should've known better! How could it betray me like this?!
"Blehh...!"
As I dry heaved, Erin glanced at me with an utterly disgusted expression.
"And what is this?"
I realized I was suspended in a gel-like substance that looked like a giant slime, my limbs restrained.
"That's antifreeze gel. It's a special liquid used to immobilize large monsters, but since you're so dangerous, we dunked you in it for safety."
Frederica's furious explanation made me attempt to move my body. I found that if I moved slowly and gently, I could wiggle a bit. But any attempt to apply force was instantly absorbed by the gel, rendering me completely immobile.
"If Erin hadn't walked in, who knows what would've happened... I've protected my chastity for 300 years, only to almost have it sullied by this lunatic..."
"No offense, but I don't care about a geezer's chastity."
"Shut up! Then why were you sucking on the tits and... and the rest of the body my No. 3 created?!"
Frederica slammed her palm down on my head, but it didn't hurt much due to her lack of strength.
'Wait, that was No. 3's body, not even hers. What's her problem?'
No. 3, meanwhile, was currently using her liquid manipulation magic to extract the mutated potion's effects from my body. Perhaps my high compatibility with the potion made it more difficult to remove, as it seemed to have penetrated deep into my system.
"Why don't you just stimulate his lower body to force it out?"
"If I do that, it might cause his dick to overgrow and go berserk, Mother."
"Such an annoyingly adaptable body! Other test subjects didn't have this issue. How compatible are you, anyway?"
While Frederica grumbled, Delphine tapped my head lightly as she used magic to scan my brain structure.
"This new mutation potion seems to have a side effect from the semen-fed beauty mandrake we used. It drastically heightens libido, which allowed the potion's effects to concentrate on the genitals. That's why it's able to induce things like erections or penis enlargement. But since your compatibility is so high, some of the ingredients entered your brain, causing it to behave as if it were producing male hormones."
"I don't understand a word you just said."
"In simpler terms," Frederica said, glaring at me, "your brain's full of dick juice, and it's making you horny."
That explanation made enough sense.
"So... it's basically a lust potion, then?"
"Not originally. It wasn't supposed to be this extreme. But with your high compatibility—or maybe just your ridiculously strong libido—it threw everything out of balance. Honestly, if you'd drunk this outside in a crowded area instead of here, the results would've been catastrophic."
If I'd gone wild in a busy city after drinking the potion, I probably would've been arrested and executed on the spot.
"The original idea was to include a small libido boost to help the potion activate its mutation effects instinctively. It was supposed to be harmless. But clearly, we need to limit the effects to the genitals and add training instructions before selling this."
As the potion's remaining effects drained from my body through my sweat glands, my dick finally returned to its normal size. That's when I realized I was still completely naked and tied up in front of all the women—Frederica excluded, of course.
"Um... could someone at least cover me up?"
"Embarrassed now? You weren't shy about swinging it around and shoving it in our faces earlier."
"That was because of the side effects!"
"Fine, he's stable now. Let him go so he can dress himself," Frederica ordered.
At her command, No. 3 used her magic to release the antifreeze gel restraining me, returning it to its flask. The material was impossible to escape by brute force unless someone mastered liquid manipulation magic like No. 3.
"Here, clothes."
Erin handed me my clothes. Grateful, I quickly slipped on my underwear and pants first. Even so, I felt uncomfortable as Frederica's gaze lingered on my lower half, making me self-conscious.
"Thanks to the potion's side effects, even Delphine ended up getting dragged into this mess."
'Well, to be fair, Delphine was supposed to be part of the experiment to verify the potion's effects...'
"So, Delphine... it was because of the potion, right? Just the potion...?"
'Erin seems like she's already decided what answer she wants to hear.'
Knowing that admitting the truth might make Erin's eyes turn blood-red again, I forced an awkward smile and dodged the question.
"Version 2 of the po tion, which limits the effects to the genitals, needs a few more days to mature before testing, Master."
"Never, under any circumstances, do that in front of me again. Just test it out, but only by yourself."
I nodded quietly. No matter the circumstances, I had no intention of getting aroused over Frederica again.
"You might have a fractured jawbone and mild concussion symptoms. It'd be best to monitor you until tomorrow before sending you back," No. 3 reported as she returned from putting away the antifreeze gel.
Frederica groaned in frustration and yelled, "He's not staying in my room! No way. And from now on, he's banned from entering!"
"But we don't have any spare rooms left for the night. We're fully booked," No. 3 calmly pointed out.
"Then shove him in the storage room."
"I'd rather sleep in Erin's room than a storage room."
"Nope. Not happening. I don't want you there."
In the end, I lost the option of staying with Erin and was half-forced to settle in the storage room.
"Erin, this is too much..."
"Don't try to sneak into my room as if it's natural."
Under normal circumstances, Erin would have allowed it, but she seemed irritated now and was firmly keeping her door shut.
Considering what I'd done earlier, I couldn't argue too much.
"I'll bring you a blanket, so wait here for a bit."
The so-called storage room wasn't much different from the homunculus dorms or even Erin's room that I'd seen before. The temperature was comfortably cool, and aside from a large flask in the middle of the room containing a female body, it looked like a livable space. If they added some furniture, it could pass for a regular bedroom.
'A custom-made homunculus, maybe?'
The body in the flask didn't surprise me much, considering where I was. It was a mature woman's form, and the resemblance to both No. 3 and Frederica was striking.
Dust covered the nameplate on the flask, so I wiped it off with my hand to read it.
"Type 0, Origin... Frederica Endymion?"
Next to it, in a smaller flask, was the head of a middle-aged man who bore a strong resemblance to Frederica—so much so that anyone would think they were siblings.
"Type 2, Production model, Frederick Endymion."
