Chapter 166: Be Cautious of Side Effects for New Products (2)
However, the overly large dick seemed too much for Delphine to handle. Rather than enjoying it, she was grimacing in pain, tears welling up in her eyes as she struggled with it being inside her.
As blood slowly returned to my lightheaded head, I began regaining my senses. That’s when I noticed Delphine writhing in discomfort, as if her insides were being twisted apart. I decided to slow down and shrink my dick to a smaller size.
I adjusted it back to my usual size.
"This should be fine now, right?"
"It’s… not fine at all…!"
Though earlier, she couldn’t even speak and was just choking on her sobs, now she was forming sentences, so it must have been a little better.
‘Maybe I went too far this time.’
Considering Delphine’s mixed elf blood meant her body had less durability and stamina than humans, I might have been too rough with her.
This time, I adjusted to a softer, more flexible structure, perfectly shaped to fit her vaginal walls. The adjustment seemed to surprise Delphine even more, and she clung tightly to me.
Because of how light her body was, it was easier to hold her up and thrust into her rather than positioning her against something.
I remembered learning during a biology lecture that if a dick is too big for a woman’s vaginal size, it causes discomfort and pain rather than pleasure. Delphine seemed to be experiencing just that.
When I adjusted to a more moderate size, my cock started bending and flexing freely inside her, rubbing against all her sensitive spots. Delphine’s lower abdomen twitched violently in response, her whole body trembling. This sensation was familiar—it felt like something I’d experienced before.
‘Is she about to cum?’
Lifting her shirt slightly, I nibbled gently on her chest, where the concentrated scent of her body lingered. That was the final push—Delphine clung to me tightly and reached her climax.
"Hhnn… haaah…! No, I can’t… , I’ll… get bred!"
Although Delphine had claimed before that, as a half-elf, she was safe from pregnancy, she knew from experiments that even half-elves could conceive with a knight’s semen. She desperately tried to wriggle away from me.
"Should I pull out, then?"
"That… might not… be safe, right?"
"Who was it that called me separately last time to warn me about the risks? You even said during the tests with your own eggs that fertilization occurred, didn’t you?"
"Well… it’s not a dangerous day right now… For elves, their fertility cycle only happens once a year…"
No wonder elves had such low reproductive rates. If they only had a few fertile days in a year…
"So, it’s safe then?"
"Y-yeah… probably? Though my cycle’s been a bit off lately… I think it’s about three months until my next one…"
Her hesitant "probably" left some doubt, but with her clinging to me so tightly, letting her go now didn’t seem fair.
I decided to release a load inside her.
"Ah… wait, what did I just do…?"
It was only after I’d finished inside her that Delphine realized what she’d said and tried to pull away in a panic. But by then, her body had already been flooded and claimed by my seed.
Crying softly, Delphine clung to me, her insides overflowing with semen as I finally let her go.
When I lifted her light body slightly, thick streams of semen spilled out of her vagina. It felt heavier and more concentrated than usual—was it because of the mandragora’s potency-enhancing effects? Or was it because I’d transformed my lower half?
Either way, stopping now was impossible.
Carefully laying the exhausted Delphine on the floor, I still felt the burning heat of arousal surging through me. My gaze naturally turned to another female in the room.
"With such strong aphrodisiac effects and the ability to freely expand and contract your dick, this could definitely sell for a fortune."
Frederica, observing the collapsed Delphine, smiled brightly, clearly pleased with the results.
"You should be happy too. We’re about to make a lot of money… Hmm? Why are you looking at me like that?"
I slowly approached Frederica, still sporting a fully erect and throbbing cock. Frederica seemed to sense something ominous and started backing away.
"Wait, no…! I’m a 300-year-old man in this body!"
"I don’t care… You have a pussy, don’t you?"
"It’s true that this body has one, but… surely not? No, absolutely not!"
Realizing the situation, Frederica tried to flee, but I grabbed her from behind.
Even though she was a legendary alchemist, her current physical body was that of an ordinary young girl. Against my enhanced physical strength, she stood no chance.
"You idiot! Cancel the transformation enlarging your dick! Too much blood is being redirected to your lower half—it’s messing with your rationality!"
"Huff… huff… You smell… so good…"
Frederica trembled in fear, struggling within my arms as though utterly disgusted. Yet, I had already started lifting her skirt with my wandering hands.
"Ah! Don’t touch my ass! Your erect tip is pressing against my ass...!"
"Feels good, doesn’t it?"
"It doesn’t feel good at all!!"
While fondling her round, firm ass visible beneath the skirt, I confirmed that despite her immature appearance, her body was fully capable of accepting a man.
"Number 3! Number 3!!"
The door burst open, and Number 3 rushed in. She froze momentarily, her usual stoic expression intact, as she took in the sight of me holding Frederica and my fully erect cock.
Even as Frederica’s warm, soft ass cheeks brushed against my tip, Number 3 hurriedly gathered mana in her hands and began casting a spell.
"I will restrain him. Forgive me…"
The experimental fluids in the surrounding laboratory started to move as if alive, attempting to bind me. However, with my enhanced instincts at their peak, I managed to evade the attacks while holding Frederica. Using my shoulder, I struck Number 3 in the chest, sending her flying.
Under normal circumstances, Number 3’s magical abilities would have overwhelmed me. But in such a confined space, with Frederica as a hostage, there was no way for the mage to defeat a knight.
"Number 3…! You insane bastard!"
Though my attention briefly shifted to Number 3, I recalled my previous experience—Number 3 wasn’t someone I could penetrate. Instead, I focused on undressing Frederica, who was a viable target.
"Ughhhh! No! Not ! I refuse in this situation!"
Number 3, seemingly determined, began manipulating the homunculus fluid surrounding her. She swallowed some liquid from a broken container nearby—a thick, sticky substance with a strangely fresh and fragrant aroma, reminiscent of semen.
"Design fully replicates Mother’s figure… Reconstructing… begins."
Ignoring her actions, I focused on subduing Frederica, who was resisting in my arms.
"Stay still. This will be over quickly."
"You never finish quickly! I’ve seen it before and just now! Why would I believe you?!"
"If you stay still, it’ll end quickly."
"How can you talk so clearly when you’re supposed to be out of your mind?! Is your brain partially paralyzed?!"
"I’m more rational than ever. So, just let me do it once."
"That’s not rational at all, you idiot!!"
Realizing further conversation with Frederica was pointless, I decided to silence her mouth entirely and force her legs apart. At that moment—
Number 3 suddenly called out, standing up to address me. However, I had no interest in her, who lacked nipples or a pussy.
"Is this… what you want?"
She began stripping off her suit with her own hands. But the sight of her flat chest, devoid of nipples, did nothing for me.
...Except now, it did.
As Number 3 discarded her clothes, her chest revealed perfectly round, pink nipples that hadn’t been there before.
‘Why does she have those?’
Previously, when I’d touched Number 3’s chest, it had been completely smooth—no nipples, no areolas, just flesh. I remembered hearing that her design was optimized for combat and administrative duties, omitting reproductive features entirely. Her chest was merely a mana-storing organ, not real breasts.
I put Frederica down and approached Number 3, grabbing her chest. Unlike before, her breasts now had a soft, elastic texture, with tender nipples that seemed to react to my touch.
"Excuse me for a moment."
As I kneaded her breasts with both hands, the way they bounced and shifted with elasticity made me smile without realizing it.
"W-weren’t you just pressing yourself against me a moment ago? And now you’re switching targets?"
"Wouldn’t you prefer bigger ones? Feeling ribs through a flat chest is hardly worth the effort."
"Ugh… this is humiliating…"
I had no interest in Frederica’s borderline inadequate body. Bigger was better for me—smaller ones were fine, but larger ones offered more fun to play with.
Number 3, who had previously shown no reaction to being touched, now had a faintly aroused expression on her face, likely due to the presence of her new nipples.
"Could it be… down there too…?"
Number 3 silently pulled down her pants. Where her groin had once been a smooth, featureless surface, now there was a soft, plump vulva tightly sealed shut.
"For such a fresh body, this isn’t very developed."
"That… looks just like…"
I ignored Frederica’s mutterings from behind. They didn’t matter.
"Why didn’t you show me this pretty pussy before?"
"D-don’t compliment me about that in such a weird way, you pervert!"
"Oh… the edges are so soft. Is it because you’ve never used it before?"
"Let me taste this beautiful pussy for a moment."
"Number 3! Just kill him already!!"
Why was Frederica the one getting angry? I was complimenting Number 3.
