Bike Ride in Jina's Grip
"But her stream starts at eight, right? I'm on the afternoon slot."
Our schedules would overlap—what was she planning to do about that? Jina pointed back and forth between Sena and herself, directing the question at me.
"Uh... then maybe start the day after tomorrow instead of tomorrow?"
"You think that'll fly?"
She flashed a smirk, like a weight had finally lifted off her chest, and it pissed me off more than a little.
"No, even if we start the day after..."
"You know once you start making excuses like that, there's no end to it, right?"
And I had zero intention of letting that slide. Jina's whole body language screamed it.
"Plus, didn't you beg me to train you properly?"
So here I was, doing exactly what she'd asked for—what's the problem? Her expression had shifted to smug triumph, saying as much without words.
"I-I want a refund."
"Sorry, but our fitness center has no refund policy."
"Then cancel it."
"Can't cancel either. You're going to the gym with me tomorrow, no exceptions."
Her eyes gleamed with wicked delight as she whispered toward me.
—Yeah, no way I'm letting you home by eight~
'Fuck, I'm screwed.'
I knew it the second I saw that look. If I stayed put, forget collabs or anything—Jina would have me pinned at the gym until she clocked out tomorrow.
Unless I bolted the moment she stepped away. Otherwise, it was inevitable.
So I shot a pleading glance at Sena, the key stakeholder in tomorrow's collab.
But Jina was faster. The instant I turned my head, hers snapped toward Sena, who let out a terrified "Eek..!" like she'd been caught by a monster.
I knew right then—no help from her.
Next, I turned to the one person in this house who could rein Jina in.
No dice. Gayeong caught my eye, smiled sweetly, then nodded at Jina in approval.
"Yeah, if you're gonna do it, do it right. But don't push him too hard. It'd be a disaster if he got hurt."
"Don't worry. I'll make sure it's even better than when I get paid for it."
She grinned at me, and my legs nearly gave out.
Anyway, that's how it went down...
"Alright, hurry up and get ready."
I'd been holed up in my room, savoring day two of my isekai kidnapping, when Jina launched her assault.
She kicked the door open like knocking was for dogs. I yanked the blanket over my lap in a panic.
"W-what the hell?!"
My fluster wasn't acting—it was real. I'd been lounging around, bored of Vtube, so I was checking out what passed for male-exclusive jerk-off material in this world.
I figured it'd be disappointing, but surprisingly, there was some decent stuff. My dick was just starting to stir when Jina burst in.
I threw the thin blanket over it, but it was useless. The thing between my legs was too monstrous, and the blanket was too sheer. If anything, it stood out more blatantly than if I'd been out in the open—the center bulged sky-high.
"S-sorry!"
She clearly hadn't anticipated this. Eyes wide, frozen solid, Jina stumbled back out.
But in that chaos, I caught her body's reaction. She whipped around too fast for certainty, but her throat bobbed like she'd swallowed hard.
And even as she stood there stunned, her eyes locked dead on the protruding spot.
'Should I be thrilled or what...?'
Just like her, it was a total blindside for me too. I tilted my head in confusion without thinking.
'Anyway...'
If she'd come all the way to my room, it meant time to get moving. My erection had mostly subsided, so I cautiously got up and headed to the bathroom.
By the time I'd showered, dried off, and changed—thirty minutes gone.
Figured Jina had shaken off her fluster by now, so I headed downstairs.
Sena greeted me, not Jina.
"Heading to the gym?"
"Yeah."
I mumbled a reply and scanned for Jina.
"Looking for Sis?"
"Huh? Yeah."
"She said she'd head out first—come down when you're ready."
"Oh?"
I started for the door, but a voice stopped me from behind.
"But... you planning to go like that?"
"Huh? Why?"
"Are you insane?"
What was wrong? I glanced down at my outfit. Unlike the house with its 24/7 blasting heat, outside would be cold, so I'd layered a khaki parka over a plain white short-sleeve tee and jeans. Casual for the gym, nothing fancy—but apparently not to Sena.
Or maybe—
"Something on my clothes?"
"No... not that..."
"Then what?"
"You wanna freeze your ass off? It's brutal out there."
She scolded like a worried mom, told me to wait, and dashed upstairs.
How long was I standing there? I kept peeking at my phone when thudding footsteps announced Sena's return—with a scarf in hand.
She trotted over and wrapped it tight around my neck.
Squeeze—
"Ack, can't breathe."
"If you wanna catch a cold and suffer, go ahead and take it off."
She snapped curtly and spun away.
"I'm off."
"Whatever."
She grumbled back the same way and vanished up the stairs to the second floor. I headed out the front door.
What greeted me was a yard the size of two living rooms combined. Jina stood at the far end.
"...You came?"
Her voice carried an awkward vibe as she welcomed me, and I inwardly freaked.
'Isn't she cold?'
Her work outfit was... bold, to say the least. Black leather rider jacket over a white tee that clung skin-tight. And leather pants that hugged every curve like a second skin—how did she even get into those? Heeled boots would've made her the ultimate badass sis, but she wore sneakers instead. Pity.
"Not cold?"
Was there some law in this world where men felt the cold way worse than women? I was already shivering fresh out the door, but Jina—who'd been waiting in this freeze far longer—stood there in thinner clothes without a tremor.
"Cold? Nah. Wait out front—I'll be right out."
She chuckled and opened a door that screamed garage, heading down.
I waited by the gate as ordered. Soon, she rolled out... on a bike.
'Oh shit...'
No wonder her outfit screamed rider. It all made sense now.
"Hop on."
Honest take? The bike suited her perfectly.
"Uh, can't we just taxi?"
They meshed like one body, but I had zero desire to climb on the back as a guy.
I tried dodging, but no use.
"You know taxis can't come into this neighborhood."
"Huh?"
"So quit whining and get on. I'll go slow."
What could I do? I gave up resisting and mounted behind her.
"Helmet."
She handed me the one dangling from the front. I jammed it on. She lowered her kickstand and turned.
Hold her waist— we're heading out.
That instant, inspiration flashed.
I awkwardly gripped the hem of her jacket.
"L-like this?"
"You'll fly off the second we start. Grip tighter."
"Like this?"
"Tighter."
The back-and-forth dragged on until Jina finally twisted toward me, exasperated.
"If it's hard to grab, just hug me."
"...Huh?"
"Hug your big sis's waist."
She arched her back invitingly, and her jacket rode up just enough to tease the panty band—and a hint of ass crack above it.
'Fuck...'
I ignored the magnetic pull of that view and wrapped my arms around her waist as ordered.
Her slim, firm midriff molded to my arms. Our bodies pressed flush.
The moment that happened, Jina shuddered in my grip... definitely from feeling my hard bulge squish against her ass.
Just minutes ago, we'd had that "accident." She'd been playing it cool, but now that sensation hit her crystal clear—probably way sharper than it should've.
"...Yeah, hold tight like that. We're going."
Her voice toward me sounded off—awkward. Was that why? She revved up fast, like she thought the motion would wash away the weirdness.
Vroom—!
She'd promised slow, but floored it from the jump. Fine by me.
"You said slow!!"
"This is slow!"
Perfect excuse to clamp her waist harder. The more I squeezed, the closer my crotch ground against her ass. Add the bike's vibrations?
My dick started rubbing right up on her.
'Shit, should've worn thinner pants.'
Then the sensation would've been razor-sharp. I glanced at her, inwardly regretting it.
Under her helmet, her exposed nape burned bright red.
'She's totally aware.'
Of course. No need for full mast—it was huge already. Little bro or not, I was a man.
Her head was probably a storm of dirty thoughts right now. Felt like it, so I eased up a bit.
Didn't want a crash—finally in this world with this face, and I'd die without properly railing anyone.
I loosened my arms around her waist. At the same time, I peeled my body off her back like I'd chickened out.
Wind whistled past the helmet, mixed with a faint 'Hoo...' sigh.
Relief? Regret? It made me smirk inside.
The whole thing struck me as hilarious.
"We're here."
"Huh? Already?"
"Yeah, see that blue building up ahead?"
About a hundred meters off loomed a seven-story structure. The whole thing was a fitness center? Maybe Jina was the richest in the family, not Sena.
She parked smoothly on the curb and turned to me.
"Go on in. I'll park quick and meet you."
"Okay."
"Helmet."
"Here."
"Inside, find the front desk—staff'll be there. Say my name, they'll handle it."
I nodded. She straightened my messy hair, then rode off to the underground lot.
Suddenly alone on an unfamiliar street with no one I knew—it really hit home.
"What, a celebrity?"
"Fuck, he's insanely hot..."
"Hey, not staring too obvious?"
"Celebrity? They say idols come here a lot..."
"An idol?"
"Any idol look like that? How'd I miss him?"
"Maybe new debut. Or trainee."
"Anyway, insanely hot..."
This world I stood in was a chastity-reversed one, where men's and women's lusts had swapped.
"Should I get his number?"
"Crazy? That chick who dropped him off is his girlfriend."
"Wonder what fucking him feels like."
"Heaven. Face alone would make you squirt."
"Shut up, bitches. He can hear you."
And thanks to that goddess who kidnapped me here, the destructive power of my new looks was off the charts.
I clung to my slipping sanity amid the nonstop filthy chatter and bolted into the building.
