Chapter Index

    .

    It wasn’t quite the best day, if I had to label it.

    But it was certainly a fulfilling one.

    I got to confirm once again the twisted depths of Lee Jiyoon’s mind—how even after hearing a recording of her kissing her own sister, she still had no intention of backing out.

    That alone made the day a worthwhile investment. But thanks to Lee Hayoon, who scurried ahead claiming she’d scouted a place, I also discovered a decent Western-style restaurant.

    She’d apparently researched it thoroughly on her phone the night before. When I absentmindedly patted her head, she squirmed, embarrassed, muttering, “D-don’t do this to me, unnie…”—an added bonus.

    No major progress was made, but it was a day of small victories.

    Before the regression, I never imagined Jiyoon’s training would unfold like this, but…

    Well. There’s a certain pleasure in methodically coaxing someone’s depraved desires to the surface.

    If I had my way, I’d hide Jiyoon behind the infirmary curtains when it’s quiet and let her listen to Hayoon and me going at it—rough, messy, and loud.

    But since I don’t have enough data yet on when the infirmary is reliably empty, I’ll just keep that thought filed away for now. Just a thought.

    Another month or so, and I’ll have a clearer pattern.

    For now, openly flirting with Hayoon in front of Jiyoon is the limit.

    To make her honest about her filthy, twisted heart.

    Relentlessly.

    Without pause.

    …Objectively speaking, nothing would be more efficient than getting them both drunk, as I’d originally planned.

    But where’s the fun in that?

    This is its own kind of entertainment.

    Or, as Jiyoon might put it—it’s no different from a game.

    Skipping straight to the “Clear!” screen would be such a waste.

    Of course, if Hayoon ever stops playing along, I’ll have to resort to that.

    But for now, things are progressing smoothly enough.

    The city, dotted with small puddles after the rain.

    As I savored the day’s achievements, my steps carried me forward in high spirits.

    3 PM.

    Still bright out. It’d be a shame to just eat and part ways now.

    So, with the remaining time—where could we go to have fun? I pondered leisurely.

    Taking my time.

    “By the way, why’d you buy that T-shirt earlier? I thought you’d hate it since I have a similar one.”

    “…J-just because.”

    “Hmm~”

    “…….”

    Under the murmur of the sisters’ trivial conversation—

    A rainbow-streaked puddle, slick with oil, crumpled beneath my loafers.

    87

    Fine.

    I’ll admit it.

    I…

    …might just have a thing for lewdness.

    Or more accurately, my body seems to have a thing for it…

    “Haaah……”

    Han Sooah, having picked at lunch before retreating to her bedroom, collapsed onto her bed and let out a heavy sigh at the ceiling.

    The cum-soaked towel she’d left crumpled on the floor? Somehow dealt with.

    The soiled underwear and sleepwear? All tossed into the washing machine.

    The lingering scent of last night’s escapades? Mostly aired out by now.

    Mostly—as in, unless someone deliberately sniffed for it, it wasn’t noticeable.

    Ugh… When she returned after her shower, the faintly musky odor still clinging to the room had thrown her into a panic.

    Luckily, the landlady didn’t seem to notice. But for Sooah—who’d curiously sniffed the sticky arousal smeared on her fingers after rubbing her clit raw—the scent was all too familiar.

    Even without that, her sense of smell had always been sharper than most.

    …Anyway.

    Sprawled on the bed, Sooah stared blankly at the ceiling, her hair barely brushed, lazily tied into a loose bundle at the nape of her neck.

    And of course, her mind drifted back to last night’s incident.

    “…….”

    Masturbation.

    She’d learned it.

    “…….”

    Normally, this was the time she’d spend shuttling between her desk and bed, reading comics.

    But today, for some reason, she wasn’t in the mood.

    …Not that she didn’t know why.

    How could comics compare to the other thing she’d discovered?

    “I’ve lost my damn mind…”

    Sooah kicked at the innocent bed with her heel, replaying yesterday’s events in her head.

    Not everything was clear, of course.

    The early parts stood out vividly, but the memories of pure pleasure afterward were hazier.

    Like how she’d dripped arousal down her thighs while pinching her clit, whimpering—

    Or how her nipples had stiffened on their own, leading her to squeeze them like she was milking herself—

    Or even sticking out her tongue, trying to lick herself—

    …Yeah. That’s about as far as she could recall.

    But for someone as pure as Sooah had been until yesterday, it was more than enough to torment her.

    The blanket over her flapped wildly for a long while, sending dust motes dancing in the faint sunlight filtering through the window.

    “…I can’t go on like this.”

    Panting lightly, she muttered to herself.

    Even comics were embarrassing to admit as a hobby—

    But masturbation?

    She needed to find a healthier pastime, stat.

    Something like golf. Or surfing.

    …No, scratch outdoor activities.

    Then what else—?

    After a brief struggle, Sooah groped around for her phone.

    Finding a new, wholesome hobby sounded good, but—

    Come to think of it, she had no idea what normal people did for fun.

    Yozora? Useless—she loved comics too.

    The school nurse? Still awkward even with forced casual speech, let alone a real conversation.

    In times like these—

    “…Where the hell is my phone?”

    —the internet was her savior.

    Since moving out, Sooah’s internet usage had skyrocketed, and she’d developed a blind faith in it—

    Like a caveman discovering fire.

    A quick search for “hobby recommendations” would surely spit out a list of options.

    She’d pick one, replace masturbation with it, and boom—problem solved.

    For a hastily concocted plan, it wasn’t half bad.

    After fruitlessly checking her usual spots, she finally remembered—she’d only done the bare minimum of cleanup before passing out last night.

    She lifted herself slightly and peeked under the pillow.

    …There it was.

    Had it been hiding there all this time?

    Warm as a freshly baked sweet potato.

    At least the battery wasn’t dead.

    Plopping back down, Sooah turned on the toasty device.

    “…….”

    The climax of the lewd comic she’d been reading yesterday burned itself into her pumpkin-colored eyes.

    “Ugh, seriously…!”

    Too angry to throw it, but—

    She hadn’t meant to see this. She’d just wanted to search for hobbies.

    Glancing furtively at the semen-stained female body and slick, monstrous cock on screen, she mashed the X button.

    Come to think of it, she’d masturbated to this scene before passing out.

    Now she remembered. Ugh…

    Anyway, useless info.

    Right now, she needed something far more wholesome than this degenerate, shameful—

    “…….”

    —but first.

    Just one quick search.

    One.

    That’s all.

    “…….”

    Clamping her lips shut, Sooah yanked the blanket over her head and tapped at the screen in the darkness.

    「Mutant-class transcendent…

    …erogenous zones」

    “…….”

    I swear—

    I swear on my life—

    No, if gods exist, I swear to them—

    Point is, I’m staking everything on this.

    It’s just curiosity.

    Nothing else.

    In fancier terms, it’s intellectual curiosity.

    Pulling her own tail and liking the pain? That defies common sense.

    If that worked, wouldn’t lion tamers in Africa just yank tails to subdue them? Ridiculous.

    So this search is purely academic.

    Just to confirm whether she’s weird or if others are the same.

    …Satisfied with her rationalization, Sooah opened her eyes and scanned the results.

    「Any mutant-class girls here? ;_;」

    「Cosplay ideas for my mutant-class GF」

    「Mutant-class < Do they go into heat? Lately, my mom’s daughter keeps barging into my room in skimpy clothes when our parents are out. Says she’s bored.」

    Huh.

    What’s “barging in” mean?

    Anyway.

    This is… something.

    The first title still left room for interpretation, but—

    The second and third? Blatant.

    Especially slapping “mutant-class GF” before “cosplay.” Clearly that kind of content.

    She skipped past them.

    “…L-let’s start with…”

    #2: Out.

    #3: Maybe later.

    Sooah tapped the first post—the one seeking mutant-class girls.

    Just in case, she peeked out from under the blanket to check the bedroom door before diving back in, heart pounding as she read.

    The gist:

    The poster was a cat-based mutant-class transcendent.

    Not particularly strong, just an ordinary office worker who disliked pain.

    But lately, she’d realized that stimulating her ears and tail felt just as good as touching her genitals…

    Yet she couldn’t bring herself to tell her long-term boyfriend, out of embarrassment.

    So during sex, she kept her ears and tail hidden, sticking to vanilla before taking care of herself at home.

    The post ended with questions: Has anyone told their partner? What do guys think about this?

    Posted a year ago.

    No idea how much traction it got, but the view count had blown past 200K, nearing 300K.

    “…….”

    Well… Obviously most guys would hate it, right?

    …Or not? Given how catgirls still popped up in comics years after transcendents appeared, maybe there was a market…

    Either way, the OP shared Sooah’s dilemma.

    The only difference? She was debating whether to confess to her boyfriend.

    Under the blanket, Sooah exhaled in relief.

    Thinking tail stimulation felt good had seemed insane—but apparently, it wasn’t that unusual.

    Still perverted, though.

    Strangely comforting.

    Next, she checked the comments.

    Maybe other girls with similar tastes had chimed in?

    “…Ew…”

    But no.

    The top comment: “Sounds hot.”

    Followed by: “The fur’s a dealbreaker though.”

    Then: “Better than S&M. Not a big deal.”

    All three had tons of upvotes.

    “The fur’s a dealbreaker” was slightly ahead, but the ratios were close.

    …The title asked for mutant-class girls, but the comments were all from guys.

    No women in sight.

    Oh well. If she kept searching, she’d find them eventually.

    The takeaway? Some men like it, some don’t.

    Good enough.

    “Next, ‘mutant-class heat’… …Huh? Sis and little bro…? …Eek…”

    And so began Han Sooah’s four-hour internet odyssey.

    The quest for a new hobby had long since vanished from her mind.

    “A karaoke room café?”

    “Yeah. They’ve board games, consoles, even the singing machines you like.”

    “…Hmm… I’ve never been.”

    “Me neither. What guy goes to places like that alone?”

    “True…”

    “So, wanna go? It’s too early to split up now.”

    “Sure. I guess… Oh, Jiyoon. You in?”

    “…Whatever.”
