The Pervert Sex Partner My Maso Girlfriend Gifted Me ♡

After the meal, I jabbed my index finger into Harin's forehead and made a show of being annoyed, but all she did was beam with delight.
Annoy her and she gets happy. Hit her and she gets happy. Practically an invincible masochist…
Even Harin had things she hated, though — things like me trying something on my own, the way I was about to today, and the idea of her sleeping with another man. Given that she was a reverse-NTR-capable masochist, I'd wondered whether she might be fine getting involved with other guys herself. But apparently being on the receiving end of that was so repulsive she wanted to bite her own tongue off. The one day I floated the idea just to test her, she burst into tears on the spot. Absolute NG word.
"Here."
"What the hell is this. A book?"
"A list I made. The reason I didn't come home all week was because I was putting this together."
"What kind of list?"
"You'll know when you look. Tell me if anything catches your eye."
We'd stopped by the park after dinner to let our stomachs settle a bit when she suddenly handed me the thing. It had the kind of expensive cover you'd expect on a major company's ledger, with the faintly terrifying words For Juwon's Exclusive Use written across it…
…Gulp, gulp.
I chugged the mystery vitality tonic she'd pulled from her bag — something like a Viper Drink MAX — and flipped it open without much thought. Once our stomachs settled, the plan was to head straight to a hotel to wrap up the date, so I figured nothing too weird would jump out. Then the photos hit my eyes.
Photos? And all of them women… Shot like graduation portraits… Not even in suits — cleavage barely hanging on… Wait, is this underwear?
They were lined up by type: cute, big-chested, beautiful, that sort of thing.
Under each photo: name, physical stats, preferred play… and so on?
"…Ah."
When I got to the photo with a big red X scrawled over it in pen, it clicked.
This woman… the one I'd been with yesterday and today…
"Figured it out?"
"This is… wait, don't tell me this is a catalog of all the sex partners you keep bringing me?"
"Yep. This is more of a sample. Just the ones I can call on short notice. Point out anyone you like and I'll go 'negotiate.'"
"Hold on — how many people is this? No, seriously, what the fuck is this…"
I flipped through the pages. At least a hundred of them.
……A hundred?
How the hell?
"Trade secret."
Harin answered as if she'd read my mind.
"I feel like I've seen some of these faces before? Celebrities, or… streamers… Wait, is this that kind of—?"
"Lookalikes, probably. No way people like that would put their faces on a list like this."
"You didn't just slap this together to mess with me?"
"For a joke, the photos came out pretty well, didn't they~? I had each of them cooperate for the shoot, so it took forever~♡"
The way she made a V-sign with both hands sealed it — this wasn't a lie.
Lookalikes were one thing, but… there was someone who'd been a teacher back in high school… and someone who'd boldly written "married woman" in the occupation field, whoever she was…
……Was this actually okay?
No — before that…
"Weren't we supposed to be on a date just the two of us today?"
"But you're going to punish Harin from here on, right? That was the plan, wasn't it?"
"Why would you think that."
"Because today I kept doing bad things right in front of you… tormented your cock… kissed you whenever I felt like it… and made a bad impression on those seniors we just met… So you're going to thoroughly mess with the girlfriend who did all those bad things, right? You know that just hitting me one-sidedly only makes me happy, so I can already picture how you'll torment me…… Heehee♡"
Then she held out a ring.
It was something I'd used a lot right after we started living together, whenever I wanted to mess with Harin — but she'd suffered so much that I'd stopped using it for a while. And now she was offering it herself.
"This is a brand-new version of the one we used last time. I bought it on the way back from making the list."
"You really are a fucking masochist. Last time you put this on you cried and made a whole scene, and you went and bought a new one yourself?"
"Yes… Today I did all sorts of things to get on your nerves too…… On purpose. Kissing you hard, gaslighting you so you couldn't even get mad…"
Gaslighting… That must have been the money talk at the restaurant.
…So that was deliberate.
"Harin did a lot of bad things, didn't she? Made you angry, right? So… hnn… hnnngh…"
Sitting on the park bench beside me, she quietly spread her legs and hiked up her skirt. It was getting dark enough that even if people walked past, they probably wouldn't notice. Or maybe someone was watching us from somewhere and we just couldn't tell — either way, my eyes were locked on this pervert's clitoris.
How much she'd masturbated with it was clear from how long and stretched it had become…
"Please torment me… Until Harin's crying and thrashing around… Torture my clit…"
"Show me your pussy."
"Okay… uhh, here… heeere~♡"
I fitted the ring she'd offered onto that perverted clitoris.
I called it a ring, but it was more like a cable tie you could pull tight, with a dense cluster of rough barbs on the inside. The moment you peeled back the hood and clamped it onto the raw flesh, it wouldn't come off — a genuinely terrifying little device.
"Gyaaahhhh… ah, ik, ihihii, i, uuuuuuugh~! Ik, i, hiiiuuung, i, ik~!"
The pain of those tiny barbs digging into her clit was apparently a lot — half delighted, half genuinely hurting — and she immediately clamped her thighs shut. From now until I decided to release her, that clitoris would stay peeled raw, and even the slightest movement would jab and prick until tears came.
…Last time I'd made her go exercise with this on, and she'd come back dripping piss the whole way.
Tighten it too hard and it stayed like that until someone else undid it… which was why even Harin had called this thing scary and bowed her head begging for mercy — one of the few tools that got that reaction out of her.
"Gyaah… ak, ah, u, uhhnnngh, uk, ihhuuuu…?! Ieuu…… uuuuuuuuuu……!! It hurts… i, ihhk, u… My crotch feels so cold… My clit keeps… bumping against my skirt… prickling… and… uhhnnngh… u…! uuuuu……"
"Can you stand?"
"Uuuung… yeah yeah… I, I didn't wear tight clothes like last time… so it, it rubs less… hnn… hnnngh… But the peeled clit keeps touching my skirt… it feels so weird… If I walk a little fast, the stuff stuck to the ring… is going to scrape and shift around… uuuu… augh~♡"
Normally she was the one leading me around, but now Harin clung to my left arm with her thighs pressed tight together. That raw, barbed training ring on her clit made every step agony, and we hadn't even reached the hotel yet — she was already hanging off me like she was about to start begging for forgiveness.
"So, did you bring anything else besides this?"
"Yeah… uuung… I prepped a lot… so I could get thoroughly tormented at the hotel after our date…"
"Even with that kink of yours, do you really enjoy bawling that much? Enough to deliberately piss someone off?"
"Yeah yeah… yeah… Punish me… Your pervert girlfriend who offered up her clit on her own… Torment me to death—♡"
"Idiot."
"Heehee… hhk… hi… iiiugh~♡ uuu♡ It's rubbing and it feels so weird♡ yeah♡ u♡ ahhhnnngh~♡ Don't shake your left hand on purpose~! Hyaaugh, ah, aaaah, uk~!"
Every careful step I took with my cane, Harin shuffled along beside me with her thighs clamped, waddling like a girl desperate to pee. The Love Hotel we were headed for was a place we visited now and then, so even with my bad eyes, my feet remembered the way. And through all of that, our clit-exposing masochist kept rubbing her thighs together and asking again.
"So… about the ones you looked at earlier… was there anyone you liked…?"
"There were a few. You put that many together — of course there were."
"Then let's call one…"
"I don't mind, but won't that cause problems? Some of those occupations looked sketchy as hell."
"All of that is… image play… The broadcaster thing is fake, the athlete thing is fake, the streamer thing obviously, and the married woman thing is all lies too…"
"Then what about the teacher who was in there?"
"That's also just someone with a similar face — a completely different person… Interested in her? Want me to call her?"
"She'll just show up if we call?"
"Yep. She should arrive around the time we get to the hotel and finish washing up."
The explanation was oddly specific.
I knew she wasn't lying, but it still didn't quite feel real. As a test, I nodded — and she stopped dead in her tracks and started tapping away on her phone.
"Texting?"
"Yeah… but you can't look, Juwon… This is a secret between girls…"
"Now you're just making me curious."
"Really, no… I'm not showing you…"
Come to think of it, this girl even had double locks on her phone, didn't she.
She finished texting from an angle I couldn't see, then smiled bashfully at the reply that came back almost immediately.
"Teacher says she'll be right over… She's looking forward to it herself, so she says to do whatever you want…"
"What kind of girl cosplays as our high school teacher, exactly?"
"Well, just… that kind of person… Because I asked her to… So she'll probably act that way too…"
"Act what way?"
"Talk like she did back then, or treat us like students, or behave like she's in class……"
What the hell was that.
That wasn't just image play anymore, was it?
Had she actually brought the real person?
"I let a lot of your nonsense slide, but when you put it like that it sounds pretty suspic—"
"Not at all!"
The moment I tried to press her, she shoved her phone in my face.
"The person coming from now on is just a slut who gets way too deep into image play, so don't overthink it — just use her."
What was that supposed to mean?
……A pink wallpaper?
………………………
…………………
……………
……What was I even suspicious about just now?
"Uh, uh… so basically, she's someone with the same kind of weird fetish as you?"
"Yep. A real pervert, I'm telling you. She kept asking what kind of teacher she was back then because she wanted to do concept play with you, Juwon… Said since we only graduated recently, she wanted to enjoy it while the memories were still fresh, or something…"
"There really are a lot of crazy bitches in this world."
"Right~♡ Ah, oh, uuung, hiiiiiuuuuung~♡ I let my guard down and pressed on my clit♡ ah♡ u♡ it hurts♡"
"You're a pretty serious idiot yourself."
"Hik♡ hit♡ so mean♡ Harin isn't an idiot girl, she's a pussy girl♡ Juwon's exclusive pussy-girl♡ huuhe♡ hek♡ augh~♡ uk♡"
The way she declared herself a pussy-girl with such pride and zero shame somehow looked endearing — which wasn't that strange. There probably weren't many people who'd genuinely say no to a beautiful woman this devoted, who even handled your sexual needs for you.
"Today's a punishment trip to the hotel, so no matter how much you beg, you're not getting any cock. Keep that in mind once we're inside."
"Uuuuuu♡ uhaaah♡ so mean♡ hhk, hnn, uuuung♡ uuuu♡ Torment me until I'm desperate♡ again, agaaain, uuuu♡ uuuu♡"
She rubbed the ringed clitoris against my thigh. It felt weirdly like a dog in heat humping its owner's leg. Every time we entered the downtown area, eyes gathered on us again — but after being stared at like this from morning till evening, I was starting to get used to it.
"Won't give me the lead in the morning, but at night you fold and act like this…"
"Uhe♡ eh♡ heee♡ eh♡ eheee♡"
Whether it was the drink or something else, my balls felt hot and heavy inside my underwear.
I found myself looking forward to whatever kind of pervert this sex partner would turn out to be.
A teacher, huh… She was a beauty who looked great in a suit, and the guys used to talk all the time about wanting to fuck her…
She'd had a stiff personality, but every sex partner so far had been some kind of screw loose — and if this wasn't even the real person, just image play…
"Hiiu, hi, Juwon, are you hard?"
"About what?"
"That teacher… She always had that stiff face like she knew nothing about sex… And you got excited thinking about putting your ass on a face like that, didn't you? Of course you did — you love that kind of play so much~♡ Fuhiihi♡"
"……………"
"It's fine. She's a pervert too. No matter how well she holds the concept, the second you shove your cock in her pussy she turns into a female monkey in one hit♡ Hehehe♡ So use her like you always do♡ Make her do all the nasty stuff you do to me♡"
With those words, we stepped into the hotel.
Whether we could really treat her that way remained to be seen — but the part about a sex partner coming was apparently true.
"Hello — or should I say, good evening? Look at you two, all grown up… It's been a year since graduation. Have you been well?"
At the entrance of the hotel we'd reserved, a beauty who looked excellent in a suit greeted us flatly from behind her glasses.
This is cosplay?
The face, the mannerisms — no matter how I looked at it, it was the real thing.
The illusion that we'd brought last year's teacher to a hotel with us immediately twisted into a rush of taboo, and my cock bulged hard against my pants.
