Turned On by My Best Friend's Pet Dog's Scent
In the early hours before dawn, while Chaeyeon slept, Yeseo woke up.
The habit still clung to her from the days when her schedule came flooding in like a tidal wave and she had to be up and ready before sunrise.
I need to pee…
Feeling the urge, she headed for the living room. After relieving herself in the bathroom and washing her hands, she stepped back out.
"I should get back to sleep…"
She was making her way toward her room, heavy with drowsiness, when—
"Hm?"
The living room should have been empty and dark. But through the city lights filtering in through the windows, she could make out something. Something that seemed to be moving. It didn't take long to figure out exactly what it was.
"Mochi…?"
Wandering around at this hour. Did dogs just not sleep much to begin with? That was what Yeseo thought as she approached him. It wasn't a deliberate decision so much as a simple impulse—she just wanted to pet the adorable little dog.
His cheeks are so soft.
Grinning to herself, she closed the distance—and then stopped cold.
"…Huh?"
Something felt off. Between Mochi's legs, something was visible, and the sight of it was deeply, uncomfortably strange. It looked a bit like a sausage, a bit like a plastic bottle. Stepping closer for a better look, Yeseo finally got a clear view of its shape.
"Kyaah…!?"
She couldn't help but jump. That thick, lengthy thing was Mochi's penis. Given its location, that should have been obvious—but she had never imagined something so enormous could be attached to his body, so it took her a moment to register what she was seeing.
Yeseo stood frozen, staring at Mochi for a long while.
"Huff, huff."
Mochi panted cutely with that adorable face of his, but what hung beneath him was anything but cute.
So that's… Mochi's dick?
Gulp. Yeseo swallowed without meaning to. Were male dogs' penises normally that big? She'd never raised one, so she had no idea. Unless you were an actual dog owner, it wasn't the kind of thing you tended to know.
Suddenly she remembered the dirty videos she used to watch all the time. She hadn't masturbated in months—too busy—so the memories were hazy, but this looked far bigger than the men in those videos.
For some reason, a faint heat of arousal began to stir.
She was still standing there in a daze, one eye locked on Mochi's cock, when—
"Woof!"
Mochi whipped his head around and barked at her, as if he'd known the whole time that she was staring.
"Ah! Sorry! Was I staring too hard?"
Yeseo startled and stumbled backward. Looking at someone else's genitals was rude, when you thought about it. Of course, it was hard to believe a puppy had barked at her for that reason—but she felt like a thief with a guilty conscience all the same.
"Well… good night…"
She'd originally planned to give his cheeks a little squeeze before bed. But after seeing that massive shaft of his, the urge had completely vanished. It was the first time she'd ever seen a real penis up close, and it left her feeling equal parts startled and afraid.
She carefully retreated to her room, shut the door, climbed into bed, and pulled the covers up. But sleep wouldn't come. Just moments ago she'd been so exhausted she could barely stand it—and yet all she could picture was Mochi's enormous manhood.
Nnh…
Her heart was pounding. It was a sensation she'd never felt before in her life.
What is this?
With a puzzled look on her face, Yeseo twisted a lock of her blonde hair between her fingers and drifted off.
The next morning, Yeseo found Chaeyeon cooking in the kitchen.
"Huh? You're the one cooking today, Chaeyeon?"
"Yeah."
"What about the housekeeper? I thought you hired one."
"I stopped having her come a while ago."
"Why? You're cleaning this huge place by yourself?"
"The house is big, sure, but it's just me and Mochi, and we barely have any stuff or furniture, so it's fine."
"A chaebol family's precious daughter, doing her own cleaning…"
"Even a chaebol heiress is still a person, Yeseo."
Before long the food was ready. Fresh from a shower and soft as a cloud, Yeseo sat down brushing out her blonde hair and started breakfast with Chaeyeon. It was a simple fried rice, but it tasted good.
After eating, she was lounging on the sofa scrolling through her phone when—
"Woof! Woof-woof!"
Having polished off his morning kibble, Mochi came panting and barking his way up onto the couch.
"Ah! Mochi?!"
Yeseo flinched and looked at him. Thankfully he wasn't erect, so she was spared another encounter with that massive thing.
When it's not hard, you can barely see it…
So it only got that huge when it was aroused? The thought sparked a quiet curiosity in her—and then she caught a whiff of something coming off Mochi's body. A strange, indescribable scent.
Come to think of it, she'd smelled something similar yesterday. Back then she'd just thought it was a nice smell, nothing more.
Ugh… something feels weird…
Now her whole body was tingling. A sharp, electric pulse ran through her lower belly, and Yeseo had no choice but to recognize what she was feeling.
Lust. Just a little—but she wanted to touch herself.
"Wow… I've actually lost it."
The words slipped out on their own. She had gotten turned on by the scent of her best friend's pet dog. It was absurd. It was also true.
What even was this Mochi? A huge dick and a dirty smell. He was a thoroughly incomprehensible dog.
"Haa… damn…"
Arousal made her breath come short, but she held it down. Yeseo had never been the type with a strong sex drive to begin with. Even now, the thought of relieving herself crossed her mind, but she decided it wasn't strong enough to act on.
"What the hell are you, really."
"Arf?"
She asked while stroking Mochi's head, but of course no real answer was coming. Yeseo snorted a little laugh and gave his cheeks a squeeze.
Still cute, though.
Even after seeing his enormous cock, she still found him adorable. Mochi wasn't a human man—he was just a dog. So it didn't leave much of an impression. Dogs could show their genitals sometimes, right? It had just been bigger than expected, that was all.
Getting turned on was… just a random spike of horniness, probably.
That happened sometimes. And even when she masturbated afterward, it never felt particularly good.
Anyway—she had absolutely not gotten aroused from smelling Mochi. That was the conclusion Yeseo settled on.
"Come on, Mochi. Let's go."
"Woof!"
Right on cue, Eun Chaeyeon emerged, ready to head out. She was wearing a short skirt and an off-shoulder knit top.
"What… since when do you get dressed up?"
Yeseo was mildly surprised. Chaeyeon was famous for never putting in effort with her appearance. Even so, her face was already nearly as beautiful as Yeseo's own—and Yeseo was a top idol—which had always inspired a tiny bit of jealousy. Now, with actual makeup and pretty clothes on top of that, she looked stunning enough to put celebrities to shame.
Of course, the real reason Yeseo was surprised was simple confusion: why was someone who never dressed up suddenly dressing up?
"Weren't you just going for a walk with Mochi?"
"…I figured we'd walk around downtown where there are lots of people."
As she said it, Chaeyeon's face flushed for some reason. Yeseo stared at her in alarm.
What is with her…
Did she actually get a boyfriend or something? But then why bring Mochi? Did the guy like dogs?
All kinds of thoughts were racing through her head when—
"Well, we're off."
"Arf!"
Chaeyeon and Mochi slipped out the door. Yeseo could only watch their retreating figures in a blank daze.
Four days passed after that. Living with Chaeyeon was uneventful enough. Every morning after breakfast, Mochi would latch onto Yeseo without fail.
"Nnh…"
And every time, that wonderful scent would hit her, and a soft moan would slip out before she could stop it. It was clearly a scent that stirred sexual desire—but Yeseo, being an entirely normal person, simply could not accept that fact.
"We're back."
"Mrrf…"
Mochi and Chaeyeon would leave early each morning and only return after the sun had gone down. For some reason, both of them always looked exhausted.
"Woof!"
"What, Mochi? You like me better than Chaeyeon-unnie?"
Mochi would wag his tail furiously and cling to Yeseo's legs or climb into her arms, and she would catch an intensely lewd scent coming off him.
"No, Mochi likes me the most, okay!?"
"…You're not actually mad, right?"
At any rate—the scent Mochi carried after coming home was distinctly different from the one she smelled in the mornings. But whatever the smell was, it never stopped stoking Yeseo's lust with brutal efficiency.
Which brought things to today.
At the usual hour, once Chaeyeon and Mochi had gone out, Yeseo quietly made her way to her room.
"……"
Unlike her usual easygoing self, she lay down on the bed with a faintly shy look on her face. She pulled off her T-shirt and sports bra. Her enormous breasts spilled free. Then she stripped off her dolphin shorts along with her light-blue panties. The panties were a little damp.
"Hah…"
A soft moan escaped as she traced her fingers over her sex. A slightly unkempt patch of platinum-blonde pubic hair sat there, untrimmed. Before long, Yeseo began circling her clitoris.
Squish, squish, squish, squish, squish!
"Hah, nnh, kh—! Haahn!"

Maybe it was because she hadn't done this in so long—but it felt so much better than any of the times before. What rose in her mind was the image of Mochi's massive cock. But Yeseo scrubbed the vision from her head, desperate to deny that she had lusted after a dog.
Squelch, squelch, squelch, squelch!
"Ha, nnh! Haahn! Hngh—!"
Of course, doing that only dulled the pleasure. At this rate, it wasn't going to be a good session at all. She was just starting to wonder if she should put on some porn when, suddenly, she noticed something on the floor of her room—one of Mochi's little outfits, lying there discarded.
This wasn't even Chaeyeon's room. Why it had ended up here, she had no idea. She also didn't care. Yeseo scrambled off the bed, snatched it up in a rush, and climbed back on.
Schlick, schlick, schlick, schlick, schlick, schlick!
"Haahn! Hnnngh! Haaahng!"
Breathing in the scent in small, furtive pulls, she started working her clit again. Slick juices poured down in streams, soaking the sheets through.
What is this… why does it feel so good…!
Masturbating while smelling Mochi felt several times better than before. Her mind went blank, as if her consciousness itself might slip away somewhere.
And then—
"Kyaaahhn…!"
Yeseo came while breathing in the scent of her best friend's pet dog—feeling a pleasure far greater than any masturbation she had ever known.
