Cock Toothbrushing — Pervert Masochist's Oral Hygiene♡

The first time I, Juwon, met a girl named Harin was back in elementary school.
Back then her figure hadn't yet ballooned into the violent curves she sports now, and her personality was gloomier than it is today.
A straight-A nerd. The silent type. The weird kid who listened to music alone. A total loser. An otaku freak.
She was the class otaku — and, on top of that, the kid from a well-off family who somehow still managed to get decent grades in a neighborhood that didn't match her background at all.
She barely spoke, studied quietly by herself, and during free periods she sealed off her eyes and ears with her phone and earbuds. There was no path to friendship, so the bullying that followed was inevitable. Teachers scolded the other kids often enough, thanks to her family's standing, but the usual empty reprimands never landed on a bunch of rowdy children — and that only became the spark that made things worse.
Stealing her school supplies was routine. They started tossing eraser shavings at her, and when she just endured it, they escalated to tripping her and leaving her scraped and bruised. One day someone snipped her hair from behind. Another time they jabbed her with a compass until she bled. Parent conferences exploded over it, and yet a week later the same harassment started all over again. By third grade, half the class was starting to discover sex, and that brand of "jokes" began too.
That was roughly when I got tangled up with Harin.
Unlike now, I was outgoing to the point of overflowing with confidence, and somehow I ended up standing up for her.
Looking back, it wasn't that I particularly wanted to protect Harin. The kids sitting next to me kept trying to mess with her and the fallout kept splashing onto me, so I picked a fight over it — and it blew up into a full-scale brawl. That's how I remember it.
They'd fling eraser shavings that bounced onto me. They'd steal her supplies and then lie and say I'd done it. They'd try to drag the kid in the next seat — me — into joining the isolation campaign. For a hot-blooded kid like I was, it was way past the line. So I went after a whole pack of boys and girls, got outnumbered and beaten down, and the next morning I'd show up with a bat I'd prepared in advance and crack their skulls one by one. I was stubborn enough that losing once didn't mean backing down. I knew that if I folded, I'd end up ostracized right alongside her, so I charged in headfirst.
…No matter how I spin it, I just hit them because they were annoying me.
There was no sense of justice in it at all.
Harin was just the excuse to beat those kids up.
I started with the boys, cracking the heads of whoever showed up to school first, one after another. The school flipped upside down. Parents got summoned. Chaos. Standing in front of all those adults and yelling, "You people can't even raise your own brats properly, that's why they pick on kids," is still one of my better childhood memories. My family had zero pull, so we nearly got crushed flat — but Harin's parents threw their weight behind us and somehow it worked out. They had photographic evidence of the physical abuse their daughter had suffered. No matter how loud the other adults got, when someone higher up the ladder had a legitimate case, they had no choice but to back off.
Money is power.
That was my third-grade memory: my own parents and teachers screaming at me to keep bowing my head even though it wasn't my fault, set against the people who actually had leverage.
After that I stayed tangled up with Harin, we grew up… my eyes went bad, my grades tanked, and I landed in a no-name local college… while Harin, for reasons I still don't understand, was supposed to go to a top medical school in the capital region and instead ended up here… the day she fought with her parents and left home, she dragged me into the place she was staying……
Somehow we started dating…
Somehow we started sleeping together…
Somehow I learned about her sexual quirks…
And I…
…How the hell did it end up like this?
"What are you thinking about?"
"Old times."
When I snapped back to myself, I realized I was sunk deep in the bathtub, answering in that same blunt tone.
The lively, loudmouthed kid had become a blunt disabled guy who barely said anything, and the gloomy silent girl had, from some turning point onward, become a dynamite-bodied little troublemaker.
The complete opposite of how things used to be.
"What kind of old times?"
"Just… back then I was the one leading you around. Now I keep wondering how it flipped like this."
"There you go again with the gloomy thoughts~! It's not like you're completely blind~! Hey, look. Look here. Can you see my body okay?"
Slap.
For someone who could barely see, a woman's body still came through just fine. Especially Harin's body, sitting right across from me — no matter what I did, it forced its way into my vision. Watermelon-sized breasts floating on the water's surface, a body without a single blemish even with her makeup washed off, and eyes looking at me overflowing with affection.
"Yeah, I can see them. I can fucking see them. What the hell did you eat to get this big? When we were kids you were flat as a board — there was nothing here. What have you been stuffing yourself with?"
"Carrots and love, obviously."
"Bullshit. You didn't sneak off and get implants without telling me, did you?"
"Other people say that all the time too~! You remember the high school girls' gossip, right? They kept bitching at me that stuffing my bra looked disgusting and I should stop, so you went off on them and chased them away! And then the rumor started that you already knew what was inside my chest!"
That had happened.
Around first year of high school, maybe?
My eyes were getting worse by then, so it was my last bit of stubborn pride.
"The guys used to stare at your tits and say those milkers could feed like ten kids no problem. Then they'd give me shit about whether I'd felt them up, whether I'd sucked on them, what the fu—"
"I don't want kids right now. I've already got such a big baby right here — why would I look anywhere else?"
"Ah, for fuck's sake— hey, cut it out. I said stop."
"Nuh-uh~! You can't even fight back anyway~!"
"Goddammit…"
When Harin came at me, there was nothing I could do. My face got buried in a pair of water-slick watermelon mounds. They had a thicker, more grounding scent of skin than any woman I'd held yesterday or the day before. Her nipples were pretty and thick enough that they looked like they'd feel good between my teeth.
"Heh… hh… hnn… heehee…"
"Don't get your hopes up. We're getting out soon."
"Aww… yeah… but…"
"I seriously told you to stop…"
She slipped a hand into the shared tub and stroked along my cock, but I tried to push her off, determined not to give her what she was hoping for.
If only my left arm still had any strength in it.
"Mm… mmhh… after the eyes, the left hand… wonder what's next?"
"Hey! Don't say creepy shit like that. Every time something else on me starts failing, the idea of leaving it all to you already freaks me the hell out, so just—"
"I think it's great~! Juwon's finally starting to match my kinks, and I'd love it if you just left everything to me and sat there quietly~!"
"The way this is going, I'm terrified of what you'll end up wanting from me."
"Nothing much. Diapers, at most?"
"You crazy bitch. There's a limit to how far you can take a joke before I stop putting up with it. Even if I end up unable to use my arms and legs, I am never asking you to change my diapers."
"…I wonder about that."
"Fuck."
I shoved her off with my still-strong right hand and barely managed to sit up. Through the blur of my vision I could make out Harin's smile. Looking after someone, serving them — that should be stressful, but this was the genuine smile of a masochist who truly enjoyed it. Those smooth, massive breasts floating above the water were almost too easy to grab without thinking, and Harin treated that as happiness too. She'd gotten so used to it that she'd once let me do it out in public and nearly gotten us both in trouble.
"You'll get used to it soon enough. I'll do anything you say. If you tell me to dance naked outside, I'll dance. If you tell me to walk on all fours, I'll walk. Remember — I'm the kind of idiot who gets happy even when you grab my chest without thinking, just like last time."
"It's orientation day. You think I'm gonna pull that shit? I already look sketchy enough groping around on the floor — if I've got a girl hanging off me on top of that…"
"'On top of that'? There's no 'on top of that.' Who's even going to give us a hard time?"
"…Upperclassmen?"
"I'll shut them up, so you don't need to worry about it."
"Who the hell are you supposed to be?"
"The best girlfriend in the world."
Being my girlfriend didn't exactly answer the question…
But she had the confidence for it — the corner of her mouth curled up.
It was the same self-assured face I think I'd once shown this idiot myself.
"I hope there are some pretty girls at college too."
She really shouldn't have said that line with that face.
"Where the fuck do you even dig these people up?"
"Trade secret."
"You're not, like, paying for them or something, right? I know you just left home and this is a one-room and you don't have that kind of money, but when I think about the ten or so girls you've already had me hold, I really can't trust you."
"It's a secret~!"
"Isn't it about time you told me? If you're mixed up in something shady, I'll figure out a way to—"
"I said it's a secret! Drop it and look at this!"
"What?"
She suddenly shoved her phone in my face.
Wrapped in plastic to keep the water off, it seemed to glow with some kind of pink light, and………
……………………………
……………………
……………
What was that?
What did I just see?
"What are you thinking about?"
When I snapped back to myself, I was answering in that same blunt tone, left with a faint sense of wrongness and déjà vu.
"Old times."
"What kind of old times?"
"Just… back then I was the one leading you around. Now I keep wondering how it flipped like this."
Hadn't we just had this conversation? Was I imagining it?
"I don't want to hear you suddenly wallowing in self-pity! You led me well back then, and that's why you ended up with such an amazing girlfriend~! You really only think about useless stuff!"
"Who's amazing? You? The bitch who's in heat year-round and was grinding her clit on the floor masturbating again this morning?"
No — maybe it really was just my imagination.
Even while I mocked her, Harin just grinned the same bashful grin and answered.
"But watching you pound away and enjoy yourself makes me feel good too~! When you snap your hips and I lick or scratch your balls from behind and you start thrusting even harder — or when I suck on your asshole and you stop mid-piston just to feel it — I can tell you're really getting off on the service I'm giving you~♡ Heeheehee♡"
"You're a real freak. A total goddamn pervert."
"Which is why I'll be collecting today's rent~♡ Come on, hurry♡ Hurryyy~♡"
"Ah, for fuck's sake… can't I just pay you in actual money…?"
"No~♡ Quick, quick-quick♡ Chika-chika~♡ Chika-chikaaa~♡"
"This girl is seriously hooked on the weirdest shit… I'm gonna lose my mind…"
"Heeheehee♡"
I rested my uneasy arm on the rim of the tub, dipped my ankles in the water, and sat perched on the edge.
"Heehee♡ Heehee♡ Here it is — Juwon's pretty-boy cock♡"
The instant that massive thing — so huge I had to wonder if it even counted as a normal cock — sprang free of the water, Harin latched onto it like a starving animal. The change had started not long after we met. At first I'd figured it was just from having too much sex, but looking back now, something about it felt off…
"Well then — excuse me for today's service~♡"
"Whuh?! Khh—!"
"Hff♡ Hheheheh~♡"
She peeled the foreskin of my thick cock all the way back, and this crazy bitch immediately smeared gel all over it.
The head went so intensely cold and sensitive that my hips bent on their own, leaving me gripping a fistful of her hair — but her deranged performance didn't stop there.
"Bfuuuuhhh~♡ Churrrbrrrrrrrr~♡ Chubrrrrrrrrr~♡"
"Ahh… ah… aaaah… fuck… ah…!!"
"Nnh, mnyam-nyam… mnyam… chubrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrt♡♡♡♡♡"
Grrrrrrrk♡ Grrrrrrk♡ Grrrrrrrrrrrt♡
The gel-foamed head scraped past her gums and teeth, got rolled around on her tongue, then rode back over her teeth and scraped hard. At first having my glans hit her teeth had hurt, but now it left behind a strange, perverted kind of relief. Midway through she'd nibble and chew on the head for extra stimulation, then use her tongue, her gums, her cheeks and the insides of her mouth to whip the gel into a massive froth — using my cockhead to scrub her teeth like…
"Chika-chika♡ Chika-chika-chikat—♡ Tsurubbbbbbb—♡"
Yeah. Chika-chika.
She was brushing her teeth with my cock.
"Chika-chika-chika-chika♡ Chika-chika-chika-chika♡ Tsurubrrrrrrrrrrrrrrrrr♡♡♡ Tsub♡ Tsubt♡ Tsubheeee♡ Bt… eh… nnhh… gueheee… bueh… bueheeeeeee……… ptoo—♡"
"Khaaah…"
When the foam built up so thick she could barely breathe, she'd spit it out over the edge of the tub, then go right back to scraping with her teeth and tongue to whip up more.
"Tsubuuhiiiiihhh… tsubt… tsurrrrrrrrrrrrrrrrrr~♡ Gofut♡ Gofuu♡ Tsurururururururururururut~♡ Tsurut♡ Tsubhu♡"
Thorough, the way you'd scrub your own teeth.
"Tsubururrrrrrrrrrrrrt~♡ Tsubt♡ Tsububububu♡ Tsubt♡ Pf♡ Tsbatt♡ Tsuburuhuuuuuuuuuuuut♡♡♡♡"
And thorough again.
Grrrrrrrk♡ Grrrrrrrk♡
"Tsubret, bet♡ Nbuheeee♡ Tsubururururururururut♡ Tsubt♡"
Chika-chika-chikat—♡
"Tsbibbbububububbbbbbt~♡ Bpurrrrrrrrrrt~♡ Tsubururururururururururut♡ Gut♡ Nppho♡ Oh♡ Oheee~♡ Grheh~♡"
Her tongue, her gums, her molars — every surface got scrubbed clean with my cockhead and that mystery gel. Then—
"Gororororororororororororororo♡♡♡♡♡"
—she filled her mouth with water, swished it with a loud, vigorous sound, spat it out, and presented a set of gleaming teeth alongside a cock without a single speck of filth left on it.
"Hff♡ Pf♡ Hnnn♡ Aah, the way the cock-feeling lingers inside my tongue and in the gaps of my gums is incredible♡ Hff, hh, nnbhh♡ My whole set of teeth feels completely violated♡ It's the best♡ Bh♡ Bheh♡ Ehe♡"
The sight of her kneading my freshly cleaned cock while flashing the teeth she'd just scrubbed with it was something profoundly, almost obscenely transgressive. Without thinking I leaned my hips down and sniffed inside her mouth — nothing but the smell of disinfectant. Not a hint of anything rotten.
"You keep that up wrong and you're going to wreck your teeth."
"It's fine! This is a medicated gel I had made with a professional's help! They even use this stuff in Japanese soaplands!"
Did she really need to say that like it was something to be proud of…
"Why are you using my dick as a toothbrush?"
"So I can feel it all day long?"
"You seriously need to check yourself into a psych ward…"
She was definitely brushing her teeth the normal way somewhere I couldn't see.
No — she had to be.
Please let her be.
Clean or not, the idea of my girlfriend walking around all day with the texture of my cock still lingering in her mouth was just too fucking terrifying.
"The gross leftover from last night's fucking is gone too. All clean now, right?"
"Yeah. You pulling stunts like this isn't exactly new. Pointing it out at this stage just makes my mouth tired."
"Heehee… I hope today's orientation has a girl who fits Juwon's cock perfectly."
"How the hell do you even keep finding girls like that…?"
……………………………
……………………
……………
No. Drop it.
"What's wrong?"
"Don't drag anyone over if they don't want to come."
"And if they want to have sex with you? If they throw a fit like the girl I brought yesterday and beg for your cock?"
"Then I wouldn't really care, but — the world's a big place, sure, how many people like that can there actually be?"
"You say that, but you've lived with me and already held about ten of them."
"Those ones were freaks, then."
"Did you… not like it?"
"No. It wasn't like anyone forced me, so…"
"…So? Don't leave it at that — how was it?! Tell me everything~!"
"I'm a guy, so… when someone's begging for it… it was just, y'know, normally good…"
"Really?!"
"…Except a few of them. Yesterday's was supposed to be carefully picked, and she was still pretty mid."
"……I see."
Harin listened, then smiled sweetly.
For some reason, the plastic-wrapped phone was in her hand again.
"I'm sorry. I made you hold a girl who tasted bad yesterday, so next time… next time… I promise… I'll pick up a really good one that Juwon will like."
She set the phone she'd briefly picked up back on the edge of the tub, then apologized to me.
I didn't understand why she was apologizing, but a cold feeling settled over me first thing in the morning.
