18. Cosplay Specialist YunaTV (28 / G-Cup Cow Girl) – Sex Buddy Ha Yeon-su Instructor♡

He grins at the saved contact, feeling a rush of satisfaction. Like a schoolgirl in the throes of her first crush, he thrashes around on the bed, practically dying of joy. His very first sex partner in life—and not just anyone, but the pilates instructor Ha Yeon-su, the object of his wet dreams.

Did ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠she enjoy fucking him that much? After just their second romp in bed, she's gone straight to partner status. Just seeing her name gets him so hyped, his dopamine levels are off the charts—he might keel over from the overdose.

And then, from Ha Yeon-su: "Hey, what do you think of this outfit?" It's a 1:1 KakaoTalk chat. Attached to the message is her selfie, snapped in front of a full-length mirror at home. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠It's just a photo of her in clothes, but her killer body makes it insanely erotic. Black yoga set—high-waisted tights that come up to just below her navel below, and above, a sports bra topped with a cropped navel tee.

"That's hot? You saying you wanna go again today?"

"What about the other one?"

Up pops the next photo. Same yoga vibe, but more stylish—less fabric overall. Gray high-waist that covers the navel below, and above, a mint-green sports bra tank top that barely covers her tits, exposing her collarbone and armpits completely.

He considers it seriously, then picks.

"Wear the first one."

He downloads the photo and sets it as her profile pic. Just trading messages has his cock twitching in his panties.

This is basically dating, right!? The conversation is so sweet, it's giving him delusions. He wants to rush over right now, hug her, fuck her senseless.

But he holds back. They went at it like animals last night till she was wrecked—she probably needs a breather.

"Ughhh! I'm losing my mind!"

Unable to contain his energy, he grabs a pillow and rolls around like an idiot.

...Maybe hit the gym early today? In the end, to burn it off, he heads to the gym first thing in the morning, works out way longer than usual, and comes back exhausted. Starving after pushing himself to the brink, he stands blankly in the kitchen, pondering lunch.

It's about time for the next mission...

Ding!

His phone chimes the second he thinks it. Midway through pulling out instant ramen from the cupboard, he bolts to snatch the phone.

This is the mission he cleared before. Female Corruption has already hit Lv.3. Lv.1 and 2 were plenty fun, but what changes come with higher levels?

Anyway, next mission first. He scrolls up to check the latest alert.

Not bad. Lately, missions aren't straight-up blackmail anymore—just special play or sex with the target. After all the extortion he's done, maybe even the God of Delinquency is tired of the pattern.

Honestly, it's a win for him. If he fucks her good and adds another Ha Yeon-su-level fuckbuddy, great. Plus, building deeper connections with women feels more thrilling than just mindless pussy-hunting.

Maybe hold back on blackmail altogether to ease into things.

Lots of thoughts swirl, but first, check the target's info.

Not BJ but TV? Probably adult streaming. Searches "YunaTV" on adult platforms—boom, top popular channel.

"Pfft!"

Clicks the pink-as-hell thumbnail and nearly chokes.

She aiming for nosebleed deaths these days...?

Pink hair, dyed that sweet strawberry milk shade, neatly braided to one side. Cute round glasses—maybe bad eyesight—and droopy eyes giving her a pure, babyfaced vibe. Face like a middle schooler, but those tits... F-cup? No, gotta be G. He's seen E-cups in person, and hers are bigger. Plus, a seductive tear mole under her eye and a noticeable dot in her cleavage peeking from the white shirt. Slim waist with navel just visible despite the huge fat sacks. Total visual violence—a monster packing every female charm.

Right now, cat ear headset on, streaming.

Ha Yeon-su's the devil of hips; this one's the devil of tits. Personally prefers ass over boobs, but watching might brainwash him. Every little move, those breasts morph and jiggle. Makes him wanna jerk off even through the screen.

"Aww~ Sorry I couldn't prep cosplay today~ Got backlog homework, and prep's been rough lately."

Wholesome vibe overall. Adult stream, but chat feels weirdly clean(?). Emojis spam alongside text. Cosplay focus makes it Japan-adjacent.

Unique character for adult streaming. Check Black Market.

Exits stream, taps [Black Market] app. Clean profile pops up.

That face is 28? Older than him? Shocked by looks, double-shocked by age. Anti-aging? Nah, cryogenically frozen since school days.

After the shock, eyebrows raise at the cheap 10k unlock for [Weakness/Secret].

Yoon Mi-na was 1 mil; just 10k?

Pays the pittance without hesitation.

Two letters appear: Cock

......Cock? Blue link attached. Clicks—links to YunaTV notice.

Notice from a month ago. Explains the cheap price—out in the open.

Big Cock Manga cosplay? She does everything... Adult streaming's wild behind the scenes.

Anyway, perfect opportunity. Conditions align too perfectly—like it was handed to him. Huge dick seeker? In Korea, he's the only candidate. (Probably.) Target posted it herself—ideal way to approach without suspicion.

Too easy; he chuckles.

Middle school: 167cm, E-cup. Kept growing—taller, bustier. So Yu-na's explosive development drew eyes from upper elementary. All-girls middle/high, but college dropouts? Truckloads of seniors fighting over her.

Huge tits + babyface. Jealousy bait, yet surprisingly many high school friends still close. Acquaintances don't hate her—worry over her like a market pup.

Reason: her personality. Easygoing, laid-back, drifting cloud vibe.

"Tits so heavy, shoulders ache...."

Sounds like fishing for compliments, but it's real for her. Everyone who knows agrees.

But at 20, debuting as cosplayer on mainstream—different story. Instant massive viewers/popularity... and report bombs. Reasons: obscenity. Just cosplaying faves, but tit-jiggling nyanyang at guys? Hated it.

Female viewers, blind to her inner self, judged by looks—terror attacks. Specific sites swarmed.

3-day ban, month ban, permaban. Migrated to adult streaming with fans.

Obvious jealousy exile, but not all bad. Bolder cosplay, higher revenue. Cleaner chat.

But adult side meant inviting guy guests. Couple cosplay skinship, cheek kisses, even grabbing her tits on cam. Idol worship dipped from excess lewdness—but Yu-na didn't care about petty image.

Not calculating. Started cosplay/streaming for fun. Does what amuses her, screw opinions. Manager stopped her from live fuck streams—blessing.

Success secret: born big tits + babyface. Pure creation passion added, but looks carry. Any girl with that face/bust succeeds. Smarter handling? Bigger leagues. But Yu-na's content now.

Adult stream cosplay in slutty fits, cat ears nyanyang—bliss.

"Did you all have fun today?"

"Sorryyy~ Next time for sure! Fun cosplay stream coming! Yuna-nyang out~ Nyang nyang!"

Ends recording.

"Phew."

Content drought, but hit manager's time quota.

"Need cosplay ideas soonnn~"

Sighs, shivers her tits with a stretch. Loosens stiff neck side-to-side, checks phone—KakaoTalk from her hired female manager.

Usual managers handle chat/misc, but hers does scheduling, content/idea meetings. Pays well, but she's scatterbrained airhead—needs her bad.

Eyes sparkle. Content drought over—can't miss this.

Rough mouth, but genuine worry.

Receives pic with warning—jaw drops.

"Whoa!"

Thick, huge size. First monster cock Yu-na's ever seen. Unconsciously presses fisted hand to her massive tits.
