If Anyone's Having an Affair, It's Going to Be Me

"Let me explain, Regina."

Think, Geum Taeyang. Remember the phone calls you overheard while slowly rolling your hips — remember exactly how all those married ladies explained things to their husbands whenever they were in danger of getting caught having affair sex with you!

Ah, no good. That memory of secret affair sex came flooding back and all the blood rushed straight to my cock.

Somewhere along the way, my head had filled up with nothing but I should've just pounded Pidi right then and there. I'd held back because taking a virgin on bare dirt felt a little off, but man, should I have just gone for it?

If using her mouth counts as cheating, and using her pussy counts as cheating too, then isn't the obvious answer to just use the pussy and cum until I'm completely drained?

"The nest isn't big enough yet, dear Husband. Increasing the aphids — no, the Pussy Nectars — will have to wait."

Yet Regina didn't get angry at her husband's infidelity. She merely counseled me carefully, asking that the baby-making sex be put on hold.

"Huh?"

"The children have entered their cocoon stage. By tomorrow, they'll become full adults."

"…So can I go fool around with Pidi and knock her up with my bare cock?"

Wait, are you forgiving me for cheating, Regina?

Oops! The words came out before the thought finished.

"I'm sorry, what's an affair, dear Husband?"

"We're married. When a husband mates with a woman other than his wife, that's called an affair."

"If mating with Pidi increases the number of Pussy Nectars, that would be a great help. Isn't that why you brought her here in the first place? To breed her, just like you did me."

Wow. My wife's sense of fidelity is fucking nonexistent.

Regina spoke of my mating with Pidi — the pregnancy, the birth, all of it — as if it were the most natural thing in the world.

Well, to be fair, the concept of marriage doesn't even exist here, does it?

I kept trying to judge this world through the lens of Earth, through the lens of humanity.

Get it together, Geum Taeyang. This is an eroge world. A world of insect monster girls.

Here, there was no need to worry about society's gaze or common sense — no such thing as judging whether pounding your cock into someone was cheating or not, like in the old world.

Ah. It feels like I've finally opened my eyes.

I had, quite literally, been a one-eyed man in a world of the two-eyed. Now I understood. Now I was finally starting to adapt to this world.

Gotcha♥

I launched a surprise attack and pinched Regina's nipple.

"Hahn…."

"Don't you ever fool around with another male!"

No concept of cheating = husband's affair sex fully sanctioned = she could do it too.

Thanks to this miraculous syllogism, I immediately launched my wife's chastity education.

I had no idea whether this world even had other males in it, but there's no loss in training her early!

"Wh-where is this coming from, all of a sudden…?"

"I won't allow it! I can pound every other pussy I want, but you're only ever allowed to take my cock for the rest of your life. I swore that when we married, remember?"

"I-I can only bear your children from now on anyway, deaaar♥"

Squeeze….

I tightened my grip on her breast.

"Say it! That you'll only look at me for the rest of your life, that only my cock gets your permission!"

"Hnnn♥ Okay, okaay. I swear, I sweaar."

"Open your mouth. Time for the oath kiss."

Churp, churuuurp….

Gulp. Gulp.

Mixing tongues with Regina, I licked every corner of her mouth, coating it with my saliva like I was marking her as my female. She quietly surrendered her body to me, swallowing down every strand of drool I fed her.

"Puwaah…."

‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠

When the long marking session finally ended, Regina panted for breath, her face flushed crimson. Her kissing experience was so limited that even though I'd been periodically feeding her air, she hadn't managed to breathe properly at all.

"Haah—. Haah—."

"Cute."

I brushed the hair stuck to her lips aside and went in for another French kiss.

Smooch.

"Dear Husband…."

And just like that, the eyes of a female craving cock flickered open.

But.

"Nope. Didn't you say the children become adults tomorrow? Who was it that told me to hold out until then?"

"Uuu… that's so meeaan."

"Get pregnant in advance. That's the only way you get a Cock Milk injection tomorrow."

Poke, poke.

I prodded Regina's lower belly.

"Yes♥"

Before bed, I stopped by the nursery to see the children's faces — but there were no faces to see.

"What the hell is this…."

Where the babies had been lying in their grass cradles, giant oval grains of rice now occupied the space instead.

Status window.

A cocoon?

These grains of rice were the preparation stage for the babies to metamorphose into their adult forms.

"They'll be full adults by tomorrow, dear Husband. I can hardly wait…."

Regina said this while stroking her own abdomen. Her belly had, at some point, swelled up round and full.

And so, the next day.

I was on my way back from feeding Pidi her grass, same as yesterday.

The message window announced that the children had become adults.

I hurried back to the nest carrying Pidi, who had passed out cold after sucking me off yet again. At the mouth of the cave, Regina was there waiting to greet me.

Alongside quite a few unfamiliar, yet somehow familiar, faces.

"…Hey there?"

The same antennae as Regina's, hair and eyes as jet-black as hers. I gazed at the mini-Reginas before me and offered a cautious greeting.

My children.

My flesh and blood — the bloodline I'd ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠believed I could never, ever have — stood clustered together at the cave entrance.

Perhaps because I was a stranger to them, the girls grabbed onto Regina's sturdy thighs and kept trying to hide behind her back.

"Everyone, this is your father. Say hi to Dad."

And already grown this big, at that….

No, wait, they grow way too fast.

Seriously, they were already fully grown. The word "children" hardly seemed adequate for them anymore. Children? Forget it — these were young women.

What should I even call them? The girls? The workers?

Honestly, you could pass them off as college students.

Unlike their mature looks, they were a bit on the short side. The ones who came up to my solar plexus were probably around 150 centimeters?

Four sisters stood before me. Eins, Zwei, Drei, Vier. When I called out their names in order, their antennae gave a start, and they peeked their heads out from beside Regina's legs.

"My Lord?"

"Is that our Lord Husband?"

"My Lord! The Queen's husband!"

"Whoa! You're super tall! Way taller than Her Majesty?!"

With a chorus of cheers, the girls came rushing toward me. In an instant, I found myself surrounded by a crowd of petite co-eds.

"Whoa, his legs are so firm!"

"Her Majesty is all soft and squishy, but our Lord is rock hard!"

These were the same girls who'd been wary of me just moments ago — but the instant they realized I was their father, the walls came down and they swarmed right in.

The surroundings turned boisterous in no time.

I chatted away with my worker daughters, savoring a long-overdue moment of parent-and-child time.

The happy hours flew by, and we returned to the nest.

When I pulled out the cleaning tools I'd received as a quest reward, a forest of hands shot up, waving eagerly.

"Cleaning! We have to clean the nest!"

"Me! Zwei wants to clean!"

"Who's going to clean the aphid?"

"Her Majesty said she's not an aphid, she's a Pussy Nectar! Me me! Drei will clean it all up!"

"The nursery needs cleaning too! We have to throw out the cocoons we tore out of! There's no garbage dump, so we have to toss them outside the cave!"

"Vier! Vier will throw them out!"

"Okay then. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Eins, you can rest for a bit."

Without anyone assigning roles, the workers divided up the tasks among themselves and got straight to it.

Workers, through and through. They're starting work on pure instinct.

I opened up the status window while watching Eins, the one loafing off among them.

‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠

Whoa. Not quite Regina's league, but far better stats than Pidi's.

When she said she'd rest while putting her little sisters to work, I half expected some kind of "Slacker" trait to be attached. It wasn't. They were probably rotating shifts as they worked.

"Regina."

"Yes, dear Husband."

"Your belly… it's really sticking out now, huh?"

"…Yees…."

Just last night, her abdomen had only been swollen enough to look like she'd overeaten a little. In a single day, it had ballooned out like a woman in her final month of pregnancy.

I gently caressed her protruding navel and whispered into her ear.

"Be ready for me tonight."

My declaration that I'd be pumping her full of Cock Milk.

The face of a mother smiling down at her children turned tomato-red in an instant.

She'd gone from mother back to female.

Anticipating my mating with Regina, I opened the system window.

"Build the Sleeping Quarters."

Since I'd prepared the building materials well in advance, the quarters rose up on the spot.

Ruuumble.

Oh? Another Potential Rating Ticket?

One for the workers, one for the soldiers. So the quests were designed that way?

Even better for me. I'll just use the next one on the soldier ants.

The tremor shaking the cave sent the workers running over.

"An earthquake?!"

"Danger! We must protect Her Majesty!"

"Evacuate the eggs! Outside the nest!"

"It's just my ability, everyone. No need to worry."

I rushed to calm the workers down, but the commotion didn't settle in the slightest. If anything, it only grew.

"Amazing! The nest got bigger in an instant!"

"Our Lord is incredible!"

Together with the chattering workers, I moved into the interior of the Sleeping Quarters.

"Wowa! The sleeping quarters!"

Flanking the long central corridor of the quarters, knee-high wooden bunks had been installed on either side.

The bunks were tightly packed with bedding made of grass and twigs, and the walls were lined wall-to-wall with drawers for storing belongings.

Th-this is….

Feeling an instinctive sense of revulsion toward the space, I hurried straight back out of the Sleeping Quarters.

The moment the workers became adults, they were busy on the move. Turns out the nest was filthy as hell — who knew?

"Uhit♥ Uhit♥ Uhiit♥"

"Vier! Don't hog all the honeydew for yourself!"

Churp….

Thanks to the workers, the nest had turned lively and bustling.

So this is what a family meal looks like….

And so dinner ended, and night fell.

"…Dear Husband…."

"Ahh. Right."

It was time for the Cock Milk Injection.

Stroking Regina's enormously pregnant belly, I brought my cock to full attention.
