The Dress Code for a Dog Collar is Obviously Being Naked, Right?
"Ugh, do we really have to do this right now? Can't I just put on the dog collar and use the dildo when we get home?"
"I want to do it now. A dedicated toilet has to obey Oppa properly, right?"
"Damn it... You're only straight-laced when it suits you."
Hyeonju's cheeks flushed with embarrassment, but she obediently stripped off her clothes, stuffed them into her bag, and reached for the dog collar, ready to hand the leash to Oppa.
Oppa, playing innocent, asked, "But why are you taking your clothes off? I said I wanted to try the dog collar and dildo. I didn't say anything about getting naked."
Hyeonju snorted derisively at his words. How could this guy, who didn't even know the first thing about fashion, act so boldly and confidently? She had to admit, his shamelessness was almost admirable. Not that she'd ever say it.
"If you don't know, just shut up. You don't even know what a dress code is, do you? When a girl wears a dog collar, the proper fashion code these days is to show off her pure white naked body. That's why idiots like you go around committing fashion terrorism in slippers and socks."
"I've always wondered— is wearing socks with slippers really that weird?"
Ignoring Oppa's question, Hyeonju dangled the leash in front of his face. Take it already and stop yapping.
Oppa shrugged and took the leash from her hand.
"I put the collar on you myself, so you put the dildo in. Here."
Hyeonju turned around and spread her pussy open with her fingers. Honey dripped from the tightly wrinkled hole.
"Whoa, what's this? I haven't even touched you yet, and your pussy's already soaked? Getting all excited already?"
"Eek! W-what are you talking about? Excited? This is just a natural bodily reaction, duh. After all the times I've been your cock hole, you think I wouldn't react like this? Are you an idiot?"
Feeling called out, Hyeonju snapped back irritably, shaking her ass to urge him on.
Oppa chuckled as he grabbed her hips and slid the dildo into her pussy hole. It was exactly the right length to poke her cervix.
The exquisite pleasure made Hyeonju let out a horny bitch's moan—"Ahhuu♥"—and twitch briefly. She didn't cum from the insertion alone, but one little touch from Oppa and she'd be done for.
"Mmm! Fits perfectly. Looks like I bought a good one, huh?"
"U-ungh... N-not bad. Oooh, I almost came just from it going in... But cumming right away would be tacky, so I held back."
"Really? I like pussy bitches that cum the second they're stuffed with cock..."
"Huh? Y-you do? W-well, I figured as much... B-but you think I'll adjust to your tastes? Sure, I'm your dedicated toilet, but I've got my pride too!"
No one had even asked her to adjust, but whatever. Secretly, to become an even better bitch pussy, she'd up the ratio of her masturbation training later. Not that her pussy needed it—Oppa’s cock aside, it was already so pathetic that a finger would make her cum on the spot.
"Anyway, let's head home already. Shopping wore me out. I wanna shower."
"You're the one who wanted to go shopping..."
Oppa grumbled under his breath but didn't push it. He wasn't the type to argue logically with his cute little sister throwing a tantrum.
"Alright, let's go."
Hyeonju dropped to her knees, planted her hands on the ground. With the red dog collar around her neck, crawling on all fours, she looked every bit the perfect bitch in heat.
Oppa smirked and asked, "What's with the pose? Not embarrassed?"
"Embarrassed? God, you know nothing about trends. With the dog collar on and the dress code perfect, next up is obviously bitch walking. Do I have to spell out every basic thing? You're so clueless."
Hyeonju demonstratively swayed her hips gracefully as she crawled on all fours. She looked just like a bitch in heat seducing a male. If only she had a tail—that would have been the finishing touch.
If Hyeonju were in the Pussy Pet class, she'd have professional training in bitch walking, but as a regular meat toilet class student, hers was just at the liberal arts level. Still, accounting for that, it was impressively good.
"Heh, you really look like a horny pussy bitch."
"Right? That's the point. Normally, you'd prep more to show off your best pussy—massage, pussy hair grooming... But you rushed me, so now I'm doing bitch walking half-assed! So annoying!"
Hyeonju shot Oppa a resentful glare.
In sincere apology, Oppa patted her head. She tried to dodge at first, rebelliously, but soon melted into a dazed expression, drooling as she nuzzled into his hand more eagerly.
There was this superstition that fingering her pussy would instantly calm her anger, but that wasn't true. A good head pat was enough.
"Okay, okay. I'll take you to a pussy massage shop for intensive care later, so don't be mad."
"Mmm♡ You better keep that promise, got it?"
That seemed to placate her. Not that her anger was scary—it melted with one pussy rub anyway.
"Now let's really head home. Oh, one thing—don't let go of that leash no matter what. Got it?"
"Why not?"
"Duh, to avoid misunderstandings. As long as you're holding the leash, people know I'm just getting pussy-trained by Oppa. Drop it, and they think I'm some naked pervert wandering around!"
"Isn't that what the signboard's for?"
"Some idiots might misread the sign! You really know nothing!"
So she said. Oppa had set the common sense himself but couldn't quite grasp Hyeonju's sensitivities. Whatever—not a big deal, so he'd comply.
After a brief spat, Hyeonju and Oppa finally set off for home. Hyeonju led with her slutty bitch walk, hips and waist bouncing lewdly, while Oppa strolled casually behind.
She wasn't used to the position, and focusing on the extra slutty flair slowed her to a crawl. No rush though, so they took it easy. Lately, with more leisure in life, even annoyances felt tolerable.
"Whoa... Is that bitch walking? First time seeing it in real life. So cool."
"Getting trained by her Oppa, probably. Shaking her ass like that to tempt him. Cute. Wish I had a little sister like that. With pussy training rights? Life would be paradise."
"Her form's spot-on too. Must've trained professionally... Onago High School?"
"Oh, that place with all the hottest bitches from around the country?"
Passersby whispered as Hyeonju and Oppa walked by, thinking they were quiet. But Hyeonju's radar, tuned to every reaction, caught it all.
Basic stuff for any Onago girl.
She puffed up with pride, chin high. Classic high school girl vanity, satisfied. Their gazes locked on her, full of lust and envy for a hot bitch like her.
As Oppa's dedicated toilet, no other man's hands would touch her, but she didn't mind this affirmation of her bitchhood.
Then—whirr—the dildo in her pussy started vibrating.
"Ahhuuuung!!! W-what are you dooooing♥ S-sudden, so suuuudeeen...♡"
"Nothing. Just hate seeing you get all smug with guys watching. Playing around."
Oppa cranked the intensity. Hyeonju froze mid-crawl, trembling and gushing pussy juice.
Grinning down at her, Oppa toyed with the remote, ramping it up and down, playing with her pussy at will.
"Uuuung♡... I-if you're gonna make my p-pussy cum, do it right♥ Turn it down when I'm close, up when I calm... I'm not a kiiiid...♥"
But she couldn't stop him. Playing with his little sister's pussy was Oppa's natural right. She could bitch from behind, but not tell him no.
"Nothing more fun than a smug sister squirming. Gonna play like this all the way home, so hurry up if you wanna end it."
"Uuuut..."
What a childish Oppa. Hyeonju grumbled inwardly, but that was it. When it came to pussy play, he was dead serious—no persuading him.
In the end, she gritted her teeth, endured, and crawled home. Somehow maintaining sanity through minimal mercy, she survived.
She thought she had...
"Ah... Oppa, what are you doing here?"
A familiar voice rang out. One that absolutely shouldn't be here.
"Oh, Mira? Saw you earlier, and now again?"
"......Fuck."
The class toilet rag from the pro-training class. Hong Mira's voice.
