The Weird Woman Who Sleeps With Her Pet Dog
Eun Chaeyeon lay on her back, staring up at the ceiling.
I was sprawled across her upper body, using her breasts as a pillow.
"Mochi? Did that feel good?"
She stroked my head and asked with a soft little laugh.
"Woof!"
I answered with a big, bright grin. I wanted to praise her for having the springiest, tastiest pussy imaginable, but since I couldn't speak human language, I sent the compliment through telepathy instead.
"I see. I really liked it too…."
Her face flushed all over again. She cupped both of my cheeks in her hands and squished them like sticky rice cakes, smiling sweetly. It was a familiar gesture — the kind of affection she showed me all the time.
"Hehe…."
Watching her smile with that still-blissed-out expression, I couldn't help grinning right back.
"But I peed myself again… sorry… You don't mind, do you? I mean… it's dirty…."
Nah.
I actually liked it.
Hell, I'd lick it up if she wanted.
I shook my head vigorously to get the point across.
"Waoof!"
"Really? You don't mind? Thank goodness… I was worried…."
Eun Chaeyeon let out a sigh of pure relief. Just a little while ago, during sex, she'd felt like some kind of bedroom-arts specialist kunoichi hell-bent on milking a man dry until he died of exhaustion. Now she was fretting over a little pee, terrified I might find it gross — and suddenly the fact that she'd been a virgin until recently came rushing back into sharp focus.
Anyway.
Lying there talking like this felt exactly like pillow talk between lovers. The telepathy made it even more so.
Right up until we'd fucked today, Eun Chaeyeon had still seemed a little uneasy about having sex with her pet dog. Now she was casually chatting about everything that had just happened between us without a shred of hesitation.
My cock had corrupted her completely.
From now on, if I came running with my hard dick swinging, she'd probably just spread those soaked folds for me on the spot.
After resting for a long while, Eun Chaeyeon finally lifted me off her chest and set me down, then got to work wiping the living room floor. She didn't forget to strip off and put away the cosplay props either.
I just watched, same as always.
This was the life of a pet dog!
Eat, shit, sleep, and fuck — a life this brilliantly radiant was what it meant to have nothing else to do!
Pitying the overworked ugly bastard I'd been in my past life, I headed to the bathroom with Eun Chaeyeon, S-rank beauty of the Eunseong Group.
We didn't have sex in the bathroom this time. The reverse cowgirl had been so intense that neither of us had any strength left to move. I'd already come three times in a row — even if I'd tried to squeeze out more, nothing would have come.
By the time we finished washing up, it was late. Midnight was creeping in.
"…Want to sleep together?"
"Woof!"
"Okay. Let's go to unnie's room."
Cradled in Eun Chaeyeon's arms, I went to her bedroom.
Moments later, the two of us were lying side by side on her bed. Ever since I'd grown bigger, we hadn't shared a bed, so the whole thing felt strangely novel.
"Good night, Mochi…."
She switched off the bedside lamp and stroked my cheek for a long time before drifting off with soft, even breaths.
Sex must have worn her out. She'd worked a lot harder than I had, so it made sense.
I was admiring her pretty face when —
Hello, Mochi. Did the sex go well?
Roselina's voice chimed in.
Popping up at exactly the right moment again — the girl had serious timing.
Yeah. Tell me about the rewards I got this time.
This time you performed the incredible reverse cowgirl position, so your rewards are quite substantial! Ah — and coming three times in a row certainly helped!
Roselina said it with a beaming smile.
An AI that celebrated her master's good news. I liked her already.
She launched into a rundown of everything I'd received. Here's the summary:
First, my penis had grown longer and thicker. I gave it a feel — yeah, the difference was definitely noticeable.
Strength Enhancement → Lv. 3
Going to be Big → Lv. 3
Custom Studded Penis → Lv. 3
All my existing skills had risen to level 3.
My newly acquired skill, I Can Hear Your Telepathy, had also climbed to level 2.
And I'd unlocked a brand-new skill.
Pheromone Temptation
Releases mysterious pheromones that make the target feel sexual attraction toward the user. Limited to young human women.
Growing this quickly is beyond anything I expected. And Pheromone Temptation, of all things! Among every skill the Sex System possesses, this one is without question top-tier!
That so?
Yes! It simply means you possess extraordinary talent for sex, Mochi. Chaeyeon must have been extremely satisfied.
Yeah, it kind of looked that way.
Indeed. When I analyzed Chaeyeon's lust levels from earlier — when she pinned you down, kissed you, and rode you reverse cowgirl — her arousal actually exceeded one hundred percent.
For real? She was that worked up?
For reference, her arousal while masturbating yesterday had been seventy percent. Apparently the typical range during sex, even when someone was wildly turned on, sat somewhere between eighty and ninety. Crossing the hundred-percent mark had to mean something significant.
Hey, Roselina.
Yes. Please go ahead.
I don't really have a sense of how fast I'm growing. Are there other cases? There's got to be someone who leveled up faster than me.
The answer that came back was a little surprising.
No. There are none. In this world, past or present, the only being to possess the Sex System is you, Mochi.
What.
So did that mean I was the only beast on Earth with human-level intelligence?
I'd figured that if a guy like me could get reborn as an animal, plenty of other people must have died and come back as animals too.
Well, yeah.
If the planet were crawling with creatures like me, there'd be a ton of cases of pet owners getting raped by their own animals. As far as I knew, that didn't happen. The world was a big place, so maybe it had a few times — but still.
Anyway, I'm going to sleep. Good work.
Yes! Sleep well!
After that, Roselina didn't speak to me again.
Starting tomorrow, I'm going to take my sex life even more seriously.
I'd fully conquered Eun Chaeyeon. My technique had leveled up too. I fell asleep vowing to spend the next stretch of days fucking her every single day.
That night I slept more peacefully than I ever had before.
The next morning, I woke up feeling completely refreshed.
Squish, squish!
"Mmmngh!"
I grabbed the huge tits of the sleeping Eun Chaeyeon beside me and kneaded them like dough.
It was the happiest morning of my entire life.
Five days had passed since the day Mochi and Chaeyeon first had cosplay sex.
Schlick, schlick, schlick, schlick, schlick!
"Hyaah! Ahhn, ahhng! Ah, ang! Haaang!"
Chaeyeon had sex with Mochi every single day.
The daily average was a staggering four rounds. Counting foreplay, Mochi came an average of five times a day, and the number of times Chaeyeon climaxed was beyond counting.
Even counting only the most earth-shattering orgasms, she'd gone over six. Once she'd tasted that kind of pleasure, she had no choice but to live every day drowning in sex.
Even now, with plans to go out already on the books, she was lying in bed fucking Mochi.
Slap! Slap! Slap! Slap!
"Haauung! Right there! Hnnh! Harder, pleaseee!"
Thwack! Thwack! Thwack! Thwack!
"Nngh! Hah, hng, hiik, hnnngh!"
The position was side-entry — both of them lying on their sides facing the same direction, the male thrusting from behind. Also known as spooning.
It was a position she'd first tried yesterday and immediately gotten hooked on. The physical pleasure wasn't the most intense she'd ever felt, but the emotional high of Mochi holding her from behind more than made up for it.
"Woof woof woof!"
Thrust, thrust, thrust, thrust!
"Hagreuuuk…! Haung! Haahk! Hnngh! Hnnh…!"
Ever since discovering that she still got wildly turned on even without the costumes, they'd been having more sex in plain clothes — but that didn't mean the cosplay had stopped.
She was still dressing up.
High elf, succubus, mermaid, and more… she'd cosplayed a whole roster of characters just to fuck Mochi.
Today's character was a dog-eared beastgirl from a popular isekai anime.
Squelch, squelch, squelch, squelch!
"Heuuk! Heeet! Hah, hah, heeeeet…!"
Every time Mochi's cock pressed hard against her vaginal walls, Chaeyeon moaned like a bitch in heat. That was part of the character's canon too — when aroused, she breathed like a dog.
And since Chaeyeon was genuinely, pervertedly turned on, those filthy little sounds spilled out of her whether she meant them to or not.
Waooof!
Spurt, spuuuurt!
"Ahk! Ahhng!"
As Mochi came, Chaeyeon hit her own climax, thin love juices dripping from her in a messy trickle.
"Hagreuuuk… hauk… hnnh, hnnngh…"
Her back arched like a drawn bow, then convulsed wildly through the aftershocks. Still riding the orgasm, Chaeyeon dropped onto all fours like a dog and shoved her big round ass back toward Mochi.
She'd switched them into doggy style.
Somehow she just knew he'd like it better this way.
And she was right — Mochi went wild.
"Wooorf! Woof! Woof!"
He barked loudly several times and pressed himself snug against her rear. Admiring her twitching little asshole, he rolled his hips and drove his shaft home.
Squelch!
"Hauu, hnnnngh…!"
"Waoof! Woof woof! Woof!"
Mochi howled again and started pounding.
Slap! Slap! Slap! Slap!
"Ahh! Hah, heeet! Hauk! So good! Getting fucked by Mochi makes me so happyyyy…!"
The dirty talk she'd once had to force out now tumbled from her lips completely naturally.
As recently as yesterday, Chaeyeon had found this change in herself unsettling.
But not anymore.
She didn't care much at all.
Getting off on fucking my pet dog… so what if that turns me on…
So what if she was a weird woman who had sex with her pet dog?
"If it feels good… heuuk, that's all that matters… haung!"
Slap! Slap! Slap! Slap!
"Hagreuuung?! Ahhhn! How?! Ahk! I came again…! Nngh!? W-wait, I'm too sensitive, Mochiii… ahk! Stop… ahk!"
Thud thud thud thud thud thud!
"Aaang! Ang! Ang! Aung!"
Sex with Mochi.
It could feel this good.
She could sink into a pleasure she'd never once experienced before in her entire life.
Chaeyeon had zero reason to stop fucking him.
The doggy-style session went on for a while. The pleasure was so much better than before that Chaeyeon couldn't help pouring out moan after moan.
It's hitting my womb again…
It sounded impossible, but it was true. At some point, whenever Mochi drove his cock in deep, she could feel her cervix getting tapped — a soft, rhythmic thump-thump.
Why does it keep getting biggeeer…!
There was no mistake. Chaeyeon had been jerking him off and blowing him every single day lately, so she was certain.
Mochi's cock was growing.
Little by little, day by day.
A shiver ran through her.
It was already big enough. What if it got even bigger from here? What if his technique got even better?
The orgasms would be so insane… I might actually go to heaven…
It already felt mind-meltingly good. How incredible would it be then?
She was thinking she might genuinely lose her mind and float off to the afterlife when —
Schliiick!
"Ahhhn…!"
Mochi buried his cock to the hilt.
Spurt! Spuuuurt!
And started cumming — a long, deep, endless release.
"Haut… hnnh, hnnngh…!"
Feeling his semen batter her womb in thick pulses, Chaeyeon came yet again — and thought to herself:
She was probably going to be late for her appointment today.
