Stage One, Round Five
Minseo's pussy was plenty wet, fully prepared to welcome a man inside, and Yumin's cock stood completely erect, ready to enter a woman's body.
"Alright, I'm putting it in now."
"...Yeah."
Yumin gripped his cock with one hand between Minseo's legs and pressed the tip against her entrance. At that moment, all pretense of composure vanished from Minseo's face. She tensed up slightly, her hands stealthily clutching the bedsheet.
Yumin began easing his cock slowly into her pussy. As expected for their second time, it was tight even though she was thoroughly soaked.
"Ngh..."
As her pussy stretched taut around his thick shaft, a short moan escaped Minseo's lips. Judging that he couldn't go all the way in yet, Yumin stopped once he'd buried about half.
"You okay? Does it hurt?"
"Not at all... I'm... f-fine?"
"Got it... Then I'll start moving."
"Yeah. Of... of course."
Yumin rocked his hips slowly, thrusting into her pussy. The soft inner walls clenched tightly around his cock, sending electric jolts of pleasure through him. Her pussy grew even wetter, gradually adapting to his girth, making each thrust a bit smoother.
At first, the thick intrusion hurt Minseo. Not the tearing agony of her first time, but a heavy ache all the same. Yet as Yumin's cock slid back and forth inside her, an indescribable sensation bloomed deep in her lower belly and spread through her entire body. It grew stronger, sharpening into something she could clearly recognize—the pure ecstasy only sex could bring.
"Ahh... haa... haaah..."
Minseo was startled by the sweet, syrupy moans spilling from her own mouth. It was mortifying, but as Yumin's cock plunged deeper, faster, and harder, she couldn't hold back anymore. She decided not to fight it—to accept Yumin honestly and savor their sex.
Once she let go, every touch felt more intense: his hands kneading her body, the soft brush of his tongue, the rigid cock stabbing into her core.
At 21 years old, Minseo couldn't have been completely ignorant or disinterested in sex between men and women. If anything, meeting Yumin as her tutor and developing feelings for him had sparked her curiosity even more. She hadn't gone so far as to binge AV out of sheer horniness, but she'd researched plenty to prepare for whatever the future might hold. Beyond the dry theory from school, she'd picked up practical, hands-on knowledge.
Then Paradise happened, and missions forced her to witness real sex up close. Live action was nothing like she'd imagined. At first, it was so shocking and embarrassing she didn't know where to look. But she couldn't avert her eyes—not when Yumin was involved, even with other guys around. Her curiosity drew her in; she watched intently. Especially Yumin's scenes with the older sisters she knew.
That brought another shock. The raw unfamiliarity of strangers fucking had repulsed her at first. But seeing Yumin with Suji, Seohyeon, and Jiwon? That was pure surprise. Suji taking charge so boldly, Seohyeon's gentle, maternal face twisting in lewd bliss, poised Jiwon unraveling—they all seemed to genuinely feel it, get off on it, love it with Yumin. It blew Minseo's mind.
But it wasn't just shock. She envied them fiercely. She wanted that too—hot, blazing sex with Yumin, just like them.
And now the chance had come. Paired with him on a mission. She'd gotten his kisses, her breasts fondled, her pussy licked and sucked, a full-body caress. Finally, penetration—losing her 20-year virginity.
Yet her first time with Yumin had disappointed her a little. There were tingles of affection, subtle waves of pleasure, but mostly pain. Nothing like the gasping moans the sisters let out.
This second round changed everything. She finally understood why they shed their everyday selves, why they moaned so shamelessly. Just like now...
"Aang... ahn... aaang..."
Minseo lost her mind as Yumin's thick cock stretched her tight pussy, scraping along her inner walls. Each thrust drew out moans that felt utterly natural now. Holding them back would've been torture.
Yumin's pace quickened. Even on her second time, Minseo could tell from watching him with the others—he was close. She braced herself.
Sure enough, he slammed deep and unleashed his load. She felt the hot cum battering her womb walls. It was bliss. A warm fullness filled her, making her feel alive as a woman—satisfied, complete. She wished it would never end.
But it faded, leaving her yearning. No time to dwell—Yumin didn't pause. He thrust hard again right away.
Minseo had barely moved, just surrendered to him, yet she felt drained like after a marathon. Her body buzzed with hypersensitivity, especially her pussy's nerves, more raw than ever.
His massive cock pounding back in overwhelmed her.
"Ahhk... Oppa... wait... haaht... stop... hnnng..."
Yumin halted at her moan-laced protest, gazing into her glazed eyes.
"Too much?"
"Haa... haa..."
"Wanna switch positions if it's rough? Doggy?"
"Haa... No..."
With the thrusting paused, Minseo caught her breath and considered his suggestion. She'd seen doggy style in missions—embarrassingly exposing for the woman. She turned him down. Not out of shame; she'd even fantasized about trying it. But not now. She wanted to see his face, lock eyes, share every sensation. No face? Unbearable.
"Haa... Keep... thrusting."
"Got it."
Somewhat recovered, she urged him on, and he obliged—slow at first, building speed, pounding her depths. The lull reignited; each stab against her cervix felt like her body was a balloon being pumped full of air. She floated weightless, mind going white.
"Haaang... haht... ah... aaang..."
She forgot where she was, what she was doing. Just electric thrills where his hands roamed, surging pleasure with every thrust. She felt his second load flooding her, his cock withdrawing—but everything else blurred into numbness.
"Minseo? Minseo-ya?"
Sensation trickled back. Yumin's anxious voice pierced the haze. Why the panic?
"Yumin... oppa... what's wrong? Something... happen?"
"Nothing... You good now?"
"Of course... I'm fine."
Why ask the obvious? She tried sitting up, but languid exhaustion pinned her down—no strength left.
Yumin dressed quickly, then helped her up and into her clothes.
"There. Let's head out."
"Huh? What about the mission?"
"We cleared it. See the success notice?"
Had there been one? She'd heard nothing, but if Yumin said so, she trusted him.
He supported her as they left the Mission Room. His group greeted the victors, as always.
"Good work, both of you."
"Minseo-ya, you okay?"
"Yeah. Just a little wiped out."
"...Right."
"You two look beat—off you go. Yumin, make sure to walk her back safe."
"Got it."
"Walking her back" meant to her hallway. Yumin guided her there, arm around her waist. The group watched, then dispersed to their rooms.
One lingered, eyes on Minseo—jealousy tinged with envy. Yumin's little stepsister, Gayeong.
Why haven't I gotten a single mission?
Everyone dragged here had done at least a few. Yet pure, untouched Gayeong—not even dated, let alone fucked—had dodged them all.
Relieved, sure, but a tiny grievance nagged. Missions terrified her—harsh penalties aside, touching a man felt impossible.
But what if, by some miracle, she got paired with oppa? Worst case, life-on-the-line rules forced it. In normal society? Incest taboo. But here...
She imagined: nestled in his muscled frame, lips meeting, tongues dancing, breasts squeezed, pussy licked, that massive cock finally sliding in.
Embarrassing. Scary. But... happy? Thrilling?
If it's a mission with oppa, we have to, right? And we're not even blood-related anyway.
Couldn't be helped.
Gayeong murmured to herself, slowly heading to her room.
