Not at Home — In a Public Restroom
"Ahhh… ahhnnngh…!"
Mochi's semen settled deep into her womb through her pussy. Feeling every pulse of it, Yeseo shuddered through another full-body convulsion.
Her entire body felt hypersensitive. A tingling erotic charge seemed to crawl over every inch of her skin, and she kept panting out lewd little breaths as her juices ran freely down her thighs.
And then—
Pop—
She lifted her hips and pulled his cock free of her cunt.
"Kyaaah…!"
Psssshhh—
The sensation was so strange she let out another sharp cry and squirted lightly. It was the first time she'd ever realized her pussy could hold that much water. Her face burned hot; she bit down hard on her peach-colored lower lip.
"Haa… hnn… heeeeh…."
A moment later Yeseo went limp and collapsed onto the floor. Still twitching from the aftershocks of pleasure, she kept dribbling Mochi's creamy load out of her cunt in thick, sticky globs.
She lay there for a long while, lost in the afterglow of climax.
"Woof!"
The cute bark snapped her back to reality. Mochi had already scrambled up onto all fours.
Even as the pleasant sensations kept rolling through her, Yeseo managed to form an actual coherent thought again. Her blue eyes trembled.
What the hell did I just do…?!?
She had fucked her best friend's pet dog.
That one short sentence covered the whole situation, and of course Yeseo's mind was a complete mess.
"Urgh…."
She felt like she might throw up. Disgust at having become the kind of freak who has sex with a pet dog crashed into her at the same time as crushing guilt over having essentially raped Mochi.
"Hoo… hoooo…."
She forced herself to breathe in and out, but her shaking heart refused to settle. She felt like she'd done something unforgivable to Mochi—and worse, the fact that fucking him had gotten her insanely turned on filled her with guilt and self-loathing.
Especially since the desire to keep fucking him was still rising inside her even now.
How am I supposed to look Eun Chaeyeon in the face like this…
If Chaeyeon ever found out her pet dog had been raped by her best friend, she'd probably go from stunned and appalled straight into furious. Cold sweat slid down Yeseo's back.
Of course she thought that—she had no idea Chaeyeon herself was already hopelessly addicted to mating with Mochi.
She couldn't bear to face Chaeyeon. She felt like an idiot for doing this at all.
Drowning in shame and stray thoughts, face burning, she was still lying there when—
"Arf arf!"
Mochi barked loudly.
"…Ah!"
The sound came from much closer than she expected. Yeseo whipped her head around in shock. He had already padded over to where she lay and was licking her palm—his cock once again rock-hard and swinging freely between his legs.
Yeseo's eyes went round.
"Woof woof!"
Mochi barked and lunged at her.
More precisely, straight at her crotch.
"Wait, Mochi?! What are you doiiing?!"
While Yeseo was still flustered, his tongue was already lapping at her clit.
Slurp slurp slurp slurp slurp slurp!
"Kyah… hnn! Heuk! Ahhng! Ahaaang…!"
Tongue out, Mochi spun rapid circles around her clitoris.
"Hnnn, ahh, hnnngh…!"
The sudden pleasure ripped moans out of her whether she wanted them or not. Strangely, it felt even better than the sex just moments before. It wasn't simply because he was hammering her most sensitive spot. The very quality of the sexual pleasure itself had changed—in the best possible way.
In any case, after a bit of that attention Yeseo started leaking thick cunt juice mixed with leftover cum again. Lust completely hijacked Mochi's brain; panting hard, he stretched out behind her where she lay on her side. His front paws gently hooked around her waist. He rubbed his fully erect cock along the sexy cleft of her ass, then tapped the swollen, flushed entrance of her pussy with the tip.
"Kyaahk…!"
Realizing exactly what was coming next, Yeseo squeezed her eyes shut against the relentless waves of arousal.
Mochi roughly shoved his massive cock straight into the mouth of her cunt.
Schlick! Schliiick!
"Nnghnnnngh…!"
She was soaked enough that his cock slid inside with almost no resistance.
"Woof!"
Barking again at the pleasure, Mochi started slamming his hips in a frenzy of side-position fucking.
Slap slap slap slap slap!
"Kyaahat! Ahhng! Khh! Aaaang!"
It was the first time in her life she'd felt the pleasure of being fucked from the side. Objectively, it seemed to hit fewer of her sweet spots than when she'd been riding him cowgirl—and yet somehow it felt far filthier, far more electric.
Schlick schlick schlick schlick schlick!
"Hngguh! Hnn, haang! Nnghkh…!"
Yeseo couldn't help screaming even more obscenely than before.
I'm losing my miiind…! I've completely lost it…! This feels so much better than when I was riding Mochi's cock…!
Every scrap of guilt she'd been feeling toward Mochi and Chaeyeon had already evaporated without a trace. Right now Yeseo was nothing but a slave to lust—a dedicated cock-sleeve for one perverted pet dog.
Squish squish—
Then his front paws started kneading the soft undersides of her breasts like dough. Pleasure surged hard and fresh juices leaked out of her in a rush.
He wasn't even touching her nipples directly. Just the gentle groping of her tits was enough to make Yeseo's pinkish light-brown nipples stiffen into hard little peaks. Her whole body kept twitching.
Every single thrust pushed her lightly over the edge. As that unfamiliar sensation kept rolling through her, filthy moans spilled out on their own.
Slap! Slap! Slap! Slap! Slap!
"Ahhng! Ang! Haaang! Shiiit…! Feels so fucking goooood…!"
Every time Mochi bottomed out, the juices pouring from her pussy sprayed out and soaked the floor. The front paws mauling her tits might as well have been living aphrodisiacs.
Curses started tumbling out of her mouth without permission. Just like Mochi, she had turned into a total pervert and dropped every last scrap of self-control, falling back into her usual rough slang.
She couldn't help it.
Her entire body felt like one giant erogenous zone.
She'd had a similar feeling earlier, but this time it wasn't just a feeling—it was as if her whole body had genuinely transformed into a sex organ.
And before long, while still getting railed from the side by Mochi, Yeseo felt a colossal orgasm that had been building bit by bit finally detonate.
"Kyaaaaaaah…!!! Kyaahnnngh…!!!"
Her hips bucked like mad. Her mind went pure white. A delicious electric buzz rippled through her lower belly as thick, viscous cunt juice gushed out in insane quantities.
Even as Yeseo experienced her first true female ejaculation, Mochi kept pounding away and unloaded his own load deep inside her.
Throb! Throoob!
"Wawawarf! Worworworf!"
Gushhhhh! Gush!
"Haang…! Ahaaang…! Hnnn…!"
Because this round had been done with his cock transformed into a dog's, the ejaculation came in three separate waves.
"Ahh! What is thiiis… hnn! Haa! Hngguh…!"
Even after that, his cock stayed locked inside her pussy for a good while longer. Yeseo rolled her hips and kept convulsing around the brand-new sensation she'd never felt before.
Quite some time passed.
At last Mochi's cock popped free with a wet sound.
"Heeuhk… heeeh…."
Completely spent, Yeseo panted with a full ahegao on her face. Mochi flopped onto his back looking just as wiped out.
A thoroughly satisfied smile sat on his muzzle.
After finishing two full rounds of sex, Baek Yeseo cleaned up the living room that was filthy with every kind of bodily fluid. Then she hauled me into the bathroom, washed my body thoroughly, and sent me out.
After that she bathed alone.
I watched through the crack in the door.
The sight of her pure white naked body got my cock hard all over again, but I forced myself to hold back. There was plenty of time; I could always do her later. Dirtying someone up the second they finished washing felt a little too mean. Mostly, though, I was just tired.
I flopped down in front of the bathroom door and spoke to Roselina.
This new skill I just got… this thing is actually insane, right?
Pleasure Increase
Amplifies sexual pleasure for everyone involved for a set duration.
"Fufu~ Incredible, wasn't it? A skill earned from sex with a brand-new beauty is bound to be something special!"
Roselina answered with a smug little laugh.
Except I was complimenting the Sex System, not her. She was just the onboard AI—why was she getting so pleased with herself?
Anyway, I buttered her up until she was happy and then dismissed her.
She wasn't wrong, though. It really was a fantastic skill.
Pleasure Increase.
The new skill with that simple name did exactly what it said on the tin: for a set period of time, it cranked sexual pleasure way up.
The catch was that it applied to everyone nearby. Even the caster—me—wasn't exempt.
The second I activated it out of curiosity, I couldn't stop myself from lunging at Baek Yeseo, and I ended up unintentionally railing her from the side. It really did feel like my brain had been completely taken over by my dick.
Still, the orgasm itself was fucking unreal.
Baek Yeseo had screamed even filthier than before; I could tell she'd climaxed on pleasure just as insane as mine.
No wonder—her lust value had spiked to 140 percent in an instant. Even Eun Chaeyeon, the living lust monster, had never broken that record.
That pretty much said it all.
Before long Baek Yeseo finished her bath and came out. Fresh and soft, she glanced at me while still naked, then pulled on a new pair of pink dolphin shorts and a white T-shirt.
The shirt must have been a size too small. It clung tight against her tits and left the exact silhouette of her nipples on full display.
The popular girl-group maknae's dangerously braless look was so goddamn hot I almost got hard again on the spot.
"……Here."
She scooped dog food into my bowl and then disappeared into her room. I diligently chowed down on kibble and topped up my stamina.
About two hours later, leash in my mouth, I walked into her room.
"Woof woof!"
I bounced around like a maniac, racing from corner to corner. It was my signal that I wanted to go for a walk.
I'd originally been an ordinary human guy, so I didn't obsess over walks the way normal dogs did.
Still, exercise mattered.
If I wanted to live a long, long time, I needed to stay healthy. The Sex System boosted my disease resistance and lifespan, sure, but it still felt nowhere near enough.
"Ah… you wanna go for a walk?"
She asked in a gentle voice.
"Woof!"
I barked brightly. Baek Yeseo said okay and pulled on a cute windbreaker. Hat and mask went on next, and just like that she was ready to head out.
We stepped outside together.
I trotted along beside her with a big sunny grin on my face.
Once we get home, we're fucking again.
My stamina had fully recovered. Recreating that entryway sex scene I'd seen in some eroge anime adaptation sounded like a fantastic idea.
And so—
I figured the walk would end completely normally, but—
"Mochi's cock… is seriously fucking huge…."
Throb throb throb throb throb throb!
By the time I came back to my senses, my dick was already gripped tight in heat-crazed Baek Yeseo's hand.
Not at home.
In a public restroom.
