Why Did You Cum So Much?

"Hngh… hh… hhaah…."

I broke out in a cold sweat watching Eun Chaeyeon, who still hadn't come back to her senses.

What the hell do I do now?

My first time having sex had felt incredible — but at the end of the day, it had been rape.

I wasn't the kind of dog who could casually commit something that awful and shrug it off. Now that the lust had been sated, the afterglow of pleasure was tangled up with guilt and dread.

A moment later, Chaeyeon pushed herself upright.

The sight of those swaying H-cup tits nearly got me going again, but this really didn't seem like the time.

"Ah…."

Her eyes trembled as she stared at the red blood that had spilled from her pussy — and at the mix of love juices and cum still leaking out of her.

Sheer terror was written all over her face.

She covered her face with both hands. Then she turned her head, eyes flying wide, and locked onto me.

Uh-oh…

A nasty premonition hit me — and right then:

SMACK!

A slap cracked across my left cheek. Chaeyeon's pretty hand slammed into the side of my face.

"Yipe!"

My head whipped sideways. Startled, I scrambled backward — and tumbled right off the bed.

THUD!

"Ghk!"

A jolt of pain shot through me, but the mattress on the floor kept me from getting hurt.

"Ah…."

Apparently she hadn't expected me to fall off the bed. A flicker of guilt crossed her face as she checked me over.

But then—

"Hic… hhng… hic."

Tears welled up. She looked at me with pure contempt, twisted her body away, and started peeling off the panties and dolphin shorts still tangled around her legs.

Rustle.

She yanked her T-shirt off too. Completely naked, she hurried toward the bathroom.

Drip. Drip.

With every step, milky fluid kept trickling from her pussy.

"Hhng… hic…."

Looking at the evidence of that creampie filled me with a warm sense of satisfaction — and at the same time, watching her sob so wretchedly made my stomach drop.

Of course she was freaked out. Her always-well-behaved pet dog had suddenly jumped her and taken her virginity.

Had there ever even been a real-world case of an adult woman getting raped by her pet dog? The world was a big place, so maybe — but it sure as hell wasn't normal.

I might be the first in the entire world.

Only then did it sink in just how completely insane what I'd done really was.

Training? What training?!

Chaeyeon might have felt good while it was happening, but she sure as hell didn't now. She'd been angry enough to slap me across the face.

At this rate, she might throw me out.

Worst case, she could quietly call someone in to have me put down. Even looking on the bright side, there was a real chance she'd drag me off to get neutered.

That can't happen.

For a second I wondered if I'd kicked a hornet's nest for nothing — then I shook my head hard.

Honestly, I'd had no choice. At this rate I was going to say goodbye to my balls. Was I supposed to just sit there and take it?

Still, there was no denying that raping Chaeyeon had made everything worse.

So what happens to me now? Do I get killed, or do I lose the family jewels?

Then… should I just keep raping her? Somehow turn her into a slave to sex?

Whooosh—

I listened to the sound of Chaeyeon washing up in the bathroom, then left the room in a fog of anxiety.

I was standing on my front paws, struggling to pull tissues free so I could wipe the various fluids off my cock, when—

A beautiful voice rang out. It was Roselina, the AI built into the Sex System.

I thought you only showed up when I called you?

Roselina proceeded to list off everything the Sex System had given me this time. To sum it up:

Just from the name, I had zero idea what that last skill even did. I figured I'd read the description properly later and sent Roselina away.

Yeah. You sleep well too.

Alone again, I tossed the cum-soaked tissues aside and trotted off to my room with the dog bed.

Blowing a load that hard into Chaeyeon's pretty pussy had left me deliciously drowsy.

Just as I was about to drift off, a fresh wave of worry bubbled up.

She's not gonna do something to me while I'm asleep, right?

This was exactly why I couldn't do bad things. Even when common sense said nothing would happen, I didn't have the guts to act like everything was fine.

"Whine…."

I whimpered in fear for a while — and then I fell asleep.

Whooosh—

Even though the shower was right there, the sound of the water felt strangely distant.

Standing naked and white under the spray, Chaeyeon stared blankly into space — then pushed her fingers into her pussy.

Splurt!

"Hnh…!"

Just how much had he cum? Mochi's semen kept pouring out without end.

"Eek! Why did you cum so much?!"

Chaeyeon recoiled in shock and scrubbed herself out as fast as she could.

As the youngest daughter of the Eunseong Group, she had been drilled thoroughly in hygiene. Even in the middle of this completely unreal situation — being raped by the pet dog she'd raised — she focused first on getting herself clean.

Whoosh—

Even after washing her whole body, she left the shower running for a long time, just letting the water soak her.

Then her mind snapped back into focus.

"What… the hell is this…."

She couldn't believe it. That her precious pet dog Mochi had raped her.

But this wasn't a dream. The feel of water on her skin proved that much. The shower noise that had seemed so far away was suddenly close again, and only then did Chaeyeon fully return to reality.

"Hhuu… hh… hhng."

She tried to calm ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠herself with deep breaths — and the dam broke all over again. She discovered that when a person went through something utterly beyond imagination, the tears just wouldn't stop.

Right after finishing her shower, she dried her hair, changed clothes, and quietly stepped out into the living room.

"Mochi? You asleep?"

She headed for Mochi's room and peered through the door, which was slightly ajar.

Mochi was out cold, snoring away without a care in the world. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Relieved, Chaeyeon slipped inside.

Click.

She made sure to lock the door behind her.

"Whew… thank god."

Clutching her still-trembling body, she let out a long breath of relief. After washing up, the thought that Mochi might rape her again had crossed her mind — she'd even steeled herself to overpower him if it came to that. She was glad it hadn't been necessary. She changed the filthy sheets.

"I'll have to wash these myself…."

There was no way she could show something like this to the housekeeper. With fresh sheets on the bed, Chaeyeon sighed and lay down.

"Hnh!"

Her crotch still tingled and throbbed. Even now, she couldn't quite believe it.

It had been her first time.

Someday she was supposed to meet a prince on a white horse — the first man she ever fell in love with — and give him the virginity she'd been saving. She never imagined Mochi would be the one to take it. That he would pin her down by force and shove that enormous cock into her.

She couldn't forgive Mochi for what he'd done. And yet, at the same time, she felt a twinge of guilt.

Maybe slapping him was a little too much…

The way Mochi had tumbled off the bed with his rock-hard erection flopping limp had looked so pathetic that — even though he'd raped her — Chaeyeon couldn't bring herself to purely hate him.

This was the puppy she'd cared for since the day he was born. She'd cherished him and loved him all this time; there was no way she could start hating him overnight.

More than anything, the fact that he was a dog made it hard to believe he'd raped her on purpose.

Losing her virginity was sad, yes — but the real reason she still couldn't stop crying was something else. It was the sheer absurdity of it: that she had been raped by her own pet dog. That something this insane had actually happened.

"Are there even cases like this?"

She picked up her smartphone, opened a search portal, and looked around. She couldn't easily find any cases of a human being raped by a dog.

Unless you were a helpless weakling, a medium-sized dog couldn't overpower you — and dogs didn't try to rape people in the first place. At most they mounted. Unless a male dog was shown a human woman's genitals and somehow recognized them as a female's entrance, he would never approach a human woman for sex on his own.

Realizing that only made her more confused.

Then why did Mochi…?

Why had he raped her? How had he managed to strip her clothes off? How had he found the entrance to her vagina so naturally and pushed that thing inside?

There wasn't just one or two things that didn't add up.

Mochi was only a slightly small medium-sized dog. Completely overpowering a healthy adult woman like Chaeyeon should have been impossible from the start.

And besides—

That was a completely human cock…

Even Chaeyeon knew a dog's penis wasn't supposed to look like that. Of course, Mochi was a new breed that resembled a Shiba Inu — one of the rare varieties currently kept only among the upper class — so information was scarce. Maybe when he got hard, it changed to something closer to a human man's.

But even granting that, something else still bothered her.

"It was… way too big…."

There was no way an ordinary medium-sized dog like Mochi could be packing something that huge.

"Did that thing… really go inside me…?"

Gulp.

Chaeyeon swallowed without meaning to.

Suddenly she remembered Mochi standing on two legs, that cock bobbing and dripping. That cute face of his, same as always — and the way he'd shoved that monstrous dick into her pussy and rolled his hips.

A ticklish heat stirred low in her belly. Without thinking, she rubbed her pressed-together thighs, stimulating her crotch.

"Hah… haah… What are you doing, Eun Chaeyeon!"

She snapped back to herself a moment later and desperately crushed down the dirty feeling, forcing her mind to calm.

Think about this rationally! Does it make any sense to get off on having sex with your own pet dog?

But it was true — it had felt so much better than the occasional times she masturbated.

Of course, as a normal person, Chaeyeon couldn't admit that. She forced herself to ignore it and turned her thoughts to something more serious instead.

Mochi's condition was clearly abnormal. Before she was a rape victim, she was Mochi's guardian — and she needed to think carefully about the situation.

For now… maybe I should put the neutering surgery on hold…?

Mochi was definitely not ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠in a normal state. She would figure out exactly why he'd raped her first. If there turned out to be nothing seriously wrong, then she'd get him neutered.

Having made that resolution, Chaeyeon closed her eyes and ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠drifted off to sleep.

In her dreams, the scene of her having sex with Mochi the night before unfolded all over again.

And the next day—

"Huff huff huff!"

"Kyaaah!"

Rub. Rub.

Chaeyeon found herself face-to-face with Mochi — grinding his massively erect cock against her leg.
