I Became a Chaebol Heiress's Pet Dog

The moment I opened my eyes in the dark, I understood.

I've been reincarnated.

Up until then, I'd assumed I was just an ordinary baby.

I should have realized something was off from the start — the person holding me wasn't a new mother. She was a girl in a school uniform.

It didn't take long to figure out the rest.

That girl was not my birth mother.

And I, as it turned out, wasn't even human.

"Huff, huff."

A dog's panting spilled from my mouth.

"Mochi! Shake!"

"Woof!"

My name is Mochi.

I'm two years old.

I became the pet dog of a chaebol family's youngest daughter.

The Eunseong Group.

One of South Korea's major chaebol conglomerates.

I had died young of overwork, and somehow I'd been reborn as the pet dog of that family's youngest daughter.

I'd thought I was a Shiba Inu.

Apparently I was just something that looked like a Shiba Inu.

Whatever.

"Aww, who's a good boy! Our adorable little Mochi! Did you miss your big sister?"

Eun Chaeyeon — freshly an adult this year — absolutely doted on me.

"Up we go."

I'd been wagging my tail by the door, and she scooped me up in both hands and hugged me tight.

Nestled against her soft chest, I smiled.

Holy shit… this is fucking amazing…

I was savoring this life for everything it was worth.

I wasn't some mutt from the countryside.

I was a high-class, elegant, noblesse-oblige dog raised by none other than the youngest daughter of the Eunseong Group.

Living large in a mansion, treated like royalty — why the hell wouldn't I be happy?

Being an ugly, talentless man had been a sad and exhausting existence, so I'd fantasized countless times about living as a beautiful woman's beloved pet.

That fantasy had come true, and I couldn't have been more thrilled.

There was just one problem.

Ah… it's up again…

I kept getting turned on.

Every time Chaeyeon held me, my tiny little dick stood straight up.

In human years I was already an adult. Being full of energy wasn't exactly strange.

Of course, it was still a problem.

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

I was a dog.

I couldn't have sex with a human!

In my past life I'd been a virgin loser, sure — but I'd been a human. A perfectly ordinary guy who could have slept with a woman if he'd just put his mind to it!

So what, was I supposed to go mount some bitch instead?

Fuck that.

Absolutely not happening.

I still preferred human women.

I had zero interest in screwing an animal. Gross.

"Whine… nnngh…"

Today, like every other day, I desperately tried to calm myself down so Chaeyeon wouldn't notice I was hard.

"Hmm? Why are you whining, Mochi? Did something happen?"

She stroked me for a while, then set me down on the floor.

I went back to my room, flopped onto my dog bed, and let out a long sigh.

Honestly?

I was hitting my limit.

I needed to vent this desire somehow — any way at all.

What do I do?

Should I try jerking off?

Do normal dogs even jack it?

I was a little scared to find out.

In the end, I just groaned and fretted until I fell asleep.

And then.

The next day.

I found myself staring at a holographic message floating right in front of my face.

"?"

What the hell is this.

A Sex System?

While I was still reeling, more messages scrolled into view.

A seductive woman's voice followed right after.

The same woman's voice read out each message as it appeared.

Hold on a second.

I cut her off.

When I asked who she was in my mind, an answer came back immediately.

"……."

I was left completely speechless.

This wasn't some sci-fi movie.

And yet an AI this advanced actually existed?

Then again, the Sex System itself already defied all logic.

I fired question after question at Roselina.

All of them about the Sex System, naturally.

Your average male dog can't exactly mate with a human woman.

Interspecies coupling was never going to be easy.

So Roselina gave me skills.

Skills grew stronger the more I had sex, she explained, and sometimes I'd unlock entirely new ones.

After hearing all that, I asked ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the most important question of all.

So how exactly am I supposed to start having sex?

I was just an ordinary Shiba-looking dog.

Even getting sex with a human woman off the ground was going to be nearly impossible.

Being a lifelong virgin in my past life was already a problem — and now I was supposed to set the mood as a goddamn dog?

If that had been easy, I wouldn't have been suffering from unfulfilled desire in the first place.

Roselina answered my question without the slightest hesitation.

Excuse me?

Click.

Her voice cut off.

Only then did I understand why I'd been given the Strength Enhancement skill.

I was thoroughly, completely rattled.

No… is this for real…?

I'd been an extremely ordinary guy.

Sure, I'd watched rape-themed porn and manga — but I'd never once actually wanted to rape a real woman. I was a decent man.

Of course, I was a dog now.

I wouldn't face any legal consequences.

Who on earth would believe a woman claiming she'd been raped by her own pet?

Even so, a wave of revulsion washed over me.

Still… rape is a bit much.

But how else was a dog supposed to have a normal relationship with a human?

Screw it, maybe I should just go for it — except the problem wasn't just my personal disgust.

Everyone treasures Chaeyeon.

She was the beloved youngest daughter of the Eunseong Group.

If she ever told someone in the Eun family that a dog had raped her — true or not — I might find myself on the express train to becoming dog stew.

That is NOT happening…!

I had no intention of dying over one round of sex. I'd rather live a long, long life without any sex at all.

Still, now that this opportunity had fallen into my lap, I did want to try it… but the idea of rape carried way too much baggage for too many reasons.

"Whine…"

I kept fretting until I finally shook my head hard.

Forget it for now.

A dog having sex with a woman was absurd to begin with.

Just being loved by Chaeyeon like this was more than enough.

With that thought, I resolved ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠not to use the Sex System.

That night.

"Big sister's home, Mochi! Were you a good boy today?"

"Woof!"

Chaeyeon came home late, as usual, after hanging out with her friends.

She must have been pretty tired.

She held me close and just lay there for a long while.

Eventually she went to her room, changed into something comfortable, clipped a leash onto me, and said—

"Let's go!"

"Woof woof!"

—and we headed out for a walk together.

Apparently dogs absolutely need to be walked.

I had a human mind, so I would have been fine without it, but there was no way Chaeyeon could know that.

Besides, I needed the exercise too.

A healthy body meant fewer illnesses and a longer life.

"The night air feels nice today."

She and I walked the nearby streets after dark.

A few joggers passed us by.

I smiled quietly to myself.

It hit me all over again how grateful I was to Chaeyeon.

She could have just had the housekeeper walk me, but she always did it herself — and that told me exactly how much she cared.

Would my past self have ever managed this?

Could I have ever been loved by someone like her?

No.

I'd have been an object of contempt, no question.

We lived in completely different worlds. We never would have even met.

I was keenly aware of just how blessed this life was.

Yeah!

I don't need sex!

As long as I can be loved for the rest of my life by a beautiful chaebol heiress, I can live without that kind of thing!

It definitely wasn't because I was scared of having sex. And it definitely wasn't because I was terrified of trying and failing.

I was in the middle of rationalizing my desires into submission when—

We finished our walk.

On the way back home.

"Oh! Phone's ringing."

Chaeyeon stopped walking and answered the call.

"Yeah! Mom! What's up?"

She chatted with her mother about this and that as she started walking again.

I trotted along on all fours, panting.

And then it happened.

"Is Mochi doing well? Of course! I'm taking great care of him! Why do you ask?"

Suddenly the conversation turned to me.

I pricked up one ear.

Come to think of it, when I was one year old, her mother had looked after me a lot.

Chaeyeon had moved out the moment she became an adult, so I hadn't seen her mother in three months already.

I was lost in idle thoughts like that when—

"Neutering surgery for Mochi? Does he really need that?"

Uh.

Just now.

I heard something I absolutely should not have heard.

"Yeah. Isn't it already past the right time? I heard five months is ideal, and he's already fifteen months old. Plus he's super well-behaved. He doesn't even mount or mark or anything…"

My heart hammered with tension.

"But you still think I should? Ah, right, you said ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠it helps prevent disease… but Mochi's always been healthy…"

I felt a cold sweat break out.

…Fuck?

No way.

Please no.

Please say you won't do it!

Tell her he doesn't need it!

"Okay. I'll take Mochi to the vet tomorrow."

Ah.

Hold on.

"Tomorrow let's go get pork cutlets, Mochi."

She ended the call with her mother, crouched down, and ruffled my head.

In that instant, my entire body locked up.

I trembled with pure fear.

The suffocating stress became too much, and I couldn't hold it in.

"WOOF! WOOF WOOF WOOF!"

"Wah! You scared me! What's wrong all of a sudden, Mochi?"

She tilted her head, but when I settled back down she just chuckled and kept walking.

I couldn't laugh.

I'd made up my mind.

Tonight — I was going to rape Eun Chaeyeon.
