Overflowing Side Effects
It wasn’t just one or two things that left me stunned.
I left Astra standing there, her chest suddenly swollen and the front of her hoodie soaked through, while I focused on the information that had just flooded my mind.
The type of side effect… Breast Milk Overflow.
I had suspected another unusual side effect might appear, but this was completely unexpected in the worst possible way.
It had somehow made a woman who had never been pregnant start producing breast milk. On top of that, her breasts had grown even larger during the process.
One could argue that simply leaking milk wasn’t the biggest problem… but the additional condition attached to it was a real headache.
‘Superhuman power is leaking?’
Hadn’t I just been going on and on about how vital superhuman power was to heroes?
That very power was now spilling out along with her milk.
I didn’t know the exact mechanism, but the word “leakage” made the future easy enough to predict.
‘Does this mean her strength and abilities as a hero will gradually weaken?’
No. Weakening would be the best-case scenario. If the leakage continued at a rapid, endless rate… she might completely lose her powers as a superhuman.
‘What the hell is this?’
I had heard stories of aging heroes whose powers slowly faded with time, but experiencing it as a side effect like this was utterly bewildering.
Compared to the leakage of superhuman power, the breast milk itself seemed almost trivial.
And then there was the release condition… that was its own kind of mess, but I pushed it aside for now. The next part was what really mattered.
“An additional condition…?”
“Huh? Siwoo, what did you just say…?”
It wasn’t the usual message that only told me the type of side effect and its release condition. This time, it also explained an extra condition attached to the current side effect. Since this kind of message had never appeared before when I used my ability, I mulled over the contents with a serious expression.
‘And why does the content have to be like this, of all things.’
It said that if Astra consumed my semen, the rate of milk production would increase. Why on earth would a condition like that even exist?
“It wasn’t like this last time… Is it because of the amount she ate? The buff seemed stronger too…”
“Um… Siwoo…? Could you please explain this to me now?”
“Ah, yes.”
I was flustered too, but Astra—who was literally leaking milk from her own breasts—had to be far more overwhelmed.
I stopped muttering to myself and explained the message that had appeared in my head to Astra, who was clutching her chest.
As expected, her face turned ashen the moment she heard about the side effect.
“M-my superhuman power is leaking?!”
The rest of the explanation was shocking enough, but as a hero herself, the part about her power leaking hit her the hardest. She urgently released sparks from her body to check her internal energy.
Fortunately, it seemed her power hadn’t started leaking yet. She let out a small sigh of relief, but her expression remained anxious and restless as she quickly continued.
“I can’t believe a side effect like this could even happen…! Unless there’s a serious problem with the body, superhuman power that has taken root almost never leaks out…!”
“So it really isn’t common?”
“Of course not! If it were, there wouldn’t be any reason to build special high-security prisons just to contain captured villains…!!”
Astra muttered in agitation, clearly disturbed by how my buff’s side effects defied common sense. But we didn’t have time to calmly study the side effect right now.
“We should release it as quickly as possible, right? You look okay for now, but if it lasts too long, your power will start draining…”
“Obviously!”
Even though she had firmly declared earlier that she would endure the side effects of my cooking, it seemed she couldn’t bear the possibility of losing the superhuman power she had worked so hard to build.
She urgently demanded that the side effect be removed, which naturally brought the release condition I had been trying to ignore back to the forefront.
“The release condition is… ugh…!!”
Yes. The release condition.
Just like how I had thoroughly massaged her breasts before, this side effect’s release condition had once again taken on a strangely erotic tone.
I had to personally suck on her breasts and extract 250ml of milk from each side.
“W-why is it that again…!”
Astra’s face flushed bright red as she recalled what had happened last time and couldn’t help but mutter. Honestly, I felt like complaining to my own ability too.
Why did it keep producing side effects like this? Was it just bad luck? Or maybe…
‘Does feeding a superhuman always trigger these kinds of side effects and release conditions?’
It could have been a coincidence the first time, but when it happened twice in such a similar way, it was hard not to suspect something more.
Of course, two times could still be coincidence, but I had a strong feeling that my ability would continue to work this way in the future.
“So… then…”
“Uuuu…”
Astra continued to agonize with a grave expression, but there was no real choice.
As I had said earlier, this particular side effect was especially fatal for her as an active hero. She needed to remove it as quickly as possible.
“Please… do it…”
At least this time, since the side effect was the same as before, she had already mentally prepared herself for her breasts to be touched.
With her face dyed as red as a tomato, Astra slowly grabbed the hem of her hoodie and lifted it upward.
‘…Wow.’
I knew I had to remove the side effect for Astra’s sake as quickly as possible, but the moment she pulled her hoodie up, I couldn’t help but let out a quiet sigh of admiration.
Those two marshmallow-like mounds that frequently appeared in my dreams—the very same ones I had touched with my own hands not long ago—were once again right before my eyes.
-Ting!!
The instant she removed her hoodie, her breasts—now even larger than before—proved too much for her bra to handle. The hook snapped with a sharp sound, and the flimsy fabric slid down, no longer able to contain her.
-Jiggle!! ♥
With nothing left to cover them, her pure white breasts bounced freely. From the tips of her prominent nipples, several drops of pale yellow liquid sprayed out, some of them landing directly on my face.
“Ugh…!!”
Even though she could feel the sensation, actually seeing milk flowing from her own breasts left Astra with an incredibly complicated expression.
She had never even had sex, let alone been pregnant, yet here she was leaking milk…
“P-please finish it quickly…”
She had no choice but to say that while desperately holding back her shame.
I had been staring at her breasts as if in a trance. Snapping back to reality—or rather, still half-enchanted—I stepped closer to her.
“Then… excuse me.”
After asking for her permission, I first placed my hand on one of her breasts, which was dripping with the pale yellow fluid.
The sensation that filled my palm was incredibly hot and soft. The moment I applied the slightest pressure, the amount of milk dripping from her nipple increased noticeably.
‘It’s smaller than before, but still…’
Compared to when they had been continuously expanding under the Breast Expansion side effect, the size was smaller. Even so, they still boasted considerable volume.
And although they were smaller, they actually felt even heavier than before.
-Jiggle~ ♥
The reason was obvious. Unlike last time, her breasts were now filled with something.
-Drip ♥
As I gently lifted her breast to feel its weight, some of the milk that had overflowed landed on the back of my hand.
I brought my hand to my mouth and tasted the milk that had spilled.
‘It’s sweet.’
Of course, it was milder compared to those overly sweet, stimulating drinks, but it had a subtle, strangely addictive sweetness. The aftertaste was slightly nutty. I had worried it might taste gamey, but it actually suited my palate perfectly.
I wanted to drink more.
Naturally harboring that thought, I kept my gaze fixed on Astra’s breasts and slowly brought my face closer.
“Astra. As I mentioned, the release condition is…”
“I-I know. You don’t have to say it out loud…”
I already knew that she understood the release condition, but I asked again anyway.
Why? Maybe because the way she looked—embarrassed yet helplessly offering her breasts—was both cute and beautiful?
I had thought this before, but the sight of Astra trembling like a small animal while presenting her chest kept planting wicked thoughts in my mind.
“Then…”
I leaned in even closer and took her nipple—which seemed slightly plumper than last time—into my mouth.
I felt her body flinch, and the moment the scent of the milk I had just tasted filled my mouth…
-Sluuurp!! ♥
“Huuu?! ♥”
Forgetting my initial plan to be gentle, I instinctively sucked hard.
-Gush!! ♥
Was it some primal instinct left over from infancy?
The moment I sucked on her breast without restraint, the milk that had been dripping one drop at a time came out several times stronger. I hurriedly swallowed it down my throat.
“Ugh…! ♥”
The pressure from swallowing caused me to suck even harder. Astra’s body trembled as she released even more milk.
-Slurp ♥ Slurp ♥
If someone only heard the sounds, they might have mistaken it for a baby feeding. The wet noises echoed through the shop, and every time I gulped down her milk, Astra let out a soft, involuntary moan.
-Crackle!!
As expected, Astra’s sparks—never one to be left out—burst out every time her body quivered, perfectly expressing her inner turmoil.
‘This is a bit uncomfortable.’
I had been sucking on her breast with only my face close, but because Astra kept flinching, my mouth kept slipping off. I reached out, grabbed her breast with my hand, and held it steady.
Using both hands to hold her breasts, I gently kneaded them while sucking even harder.
“Huuu…! ♥”
When I massaged them with my hands, even more milk flowed out. As I swallowed it, milk began leaking from the other breast that I wasn’t sucking on.
-Splatter! ♥
‘What a waste.’
Did milk normally flow so freely from the untouched side as well?
Feeling puzzled, I quickly pulled away and took the other nipple into my mouth.
The sudden warm, slightly rough sensation on the breast she hadn’t been expecting made Astra cover her mouth, barely holding back the moan that threatened to escape.
-Crackle!!
But the moment she tried to suppress it, the electricity that had been leaking out in small bursts exploded even stronger, delivering a light static shock to me.
‘Ow. That stings.’
The electricity made me flinch involuntarily, which caused me to bite down slightly harder with my teeth while sucking.
-Chomp ♥
“Huuuup?! ♥♥”
I had been trying to suck as gently as possible, but I ended up lightly biting her nipple with my front teeth.
A superhuman’s body wouldn’t be injured by something like that, but the stimulation must have been intense because the amount of milk pouring out increased dramatically.
-Drip drip!! ♥
‘Damn it.’
But while I was sucking on one breast, milk kept flowing from the other and wetting the floor. I pulled my mouth away, grabbed both breasts with my hands, and pressed them together.
“Huu… ♥ S-Siwoo? Why suddenly…”
“I just thought of a way to do this faster.”
The release condition clearly required me to suck from both breasts separately, but doing them one at a time would take too long.
So… like this.
-Chuup ♥
“Nngh?! ♥”
I pressed Astra’s breasts together and sucked on both nipples at the same time.
I squeezed them firmly so I could fit both nipples into my mouth at once. When I pressed down hard with my hands, red handprints bloomed across her previously pure white skin.
-…Gush ♥
“…Ugh… ah, down there…”
“Slurp… ♥ Yes?”
“N-nothing…”
I thought I heard a sound that was slightly different from the noise of milk flowing, but Astra turned bright red and insisted it was nothing.
I continued kneading and sucking on her breasts for some time.
-Drip… ♥ Drip… ♥
‘Hmm?’
The milk that had been flowing quite strongly at first gradually began to weaken.
I sucked harder and squeezed her breasts more firmly, but only a few drops came out at a time.
‘I still haven’t met the release condition yet…’
I tried using my tongue to catch every last drop and even gently bit her nipples with my teeth, but no more milk came out.
-Pop ♥
I must have sucked hard, because when I pulled my mouth away, I heard the sound of air rushing in. I looked at Astra and said,
“Um… it’s not coming out anymore.”
“Huu… What? Then has the side effect been removed…?”
“No. That’s not it.”
It wasn’t that the side effect had been removed and the milk stopped. Her breasts had simply run out of milk.
Hearing that, Astra spoke with tears welling up in her eyes.
“Then what do we do?!”
“We’ll have to wait until more comes out…”
“If we wait and my superhuman power starts leaking… uuu. Then everything will be backwards…”
Desperate to prevent her power from leaking, Astra fidgeted anxiously and even grabbed her own nipples, tugging on them.
-Squeeze ♥
‘Guh.’
The sight of a beautiful woman pulling on her own nipples was incredibly erotic, yet Astra didn’t seem to care how she looked as she tormented her own breasts.
-Drip ♥
But even then, only a few drops came out. And since I hadn’t sucked it out with my mouth, it probably didn’t count toward the release condition.
‘At this rate, there’s no way we’ll reach 250ml…’
We would probably have to wait at least several hours for her breasts to fill up again.
And though it was just my intuition, I had a feeling that even if she seemed fine now, her superhuman power would slowly begin to leak after a few hours.
‘…Ah.’
The moment I faced that reality, a piece of information I had been trying to ignore resurfaced.
It was the “additional condition” that had only appeared with this particular side effect—something that had never shown up before.
-Additional Condition: Consuming the chef’s semen will increase the rate of breast milk production.
‘Because of this?’
It was almost as if the additional condition had been prepared specifically for this exact situation.
I didn’t know why such a condition existed, but if it worked exactly as written…
“……Um… Siwoo?”
The moment my thoughts reached that point, Astra seemed to realize the same thing. With an expression like she wanted to die from embarrassment, she opened her mouth.
“…Earlier… you said an additional condition appeared too, right…?”
-Glance.
Her gaze fixed somewhere.
