Stage Two, Round Four
Yoo-min couldn't hold back any longer without thrusting in at least once. Skipping all foreplay, he hoisted up Jiwon's legs—her ankles bound together—high into the air. His hand went straight to her exposed pussy. He slipped his fingers between the vertical slit. It was already wet. He caressed her inner folds before inserting into the source of that clear, transparent nectar—her vagina. The inside felt inhumanly hot, as if mirroring the burning desire surging through her right now. Afraid his fingers might cook if he lingered, Yoo-min moved them fast. But as he pistoned into her rapidly, Jiwon only grew hotter. Love juices streamed from her pussy; she needed no more teasing. And neither could Yoo-min wait anymore.
He plunged his cock straight into her vagina. Her inner walls clamped down hot and tight around him. Wrapping his arms around her lifted thighs, he began shaking his hips. As excited as Yoo-min was, Jiwon was even more so—far more. She'd grown accustomed to bondage play with him through repeated sessions, so the mission's tame content had left her a bit disappointed. But he'd bound her with his own clothes. That unexpected twist thrilled her beyond measure, especially since it was his voluntary choice, not forced by the mission. With her eyes blindfolded, the man pounding into her didn't feel like the Yoo-min she once knew. So formal speech slipped from her lips. And as his thrusts grew fiercer bit by bit, it came even more naturally.
"Ahhng... It's... too intense... Ahuut... Please... Hnguut... Go easy... on me..."
Did she really want him to go easy? Did she truly wish for the cock ravaging her depths to slow down? If so, it was her mistake. Those whimpering pleas laced with formality only fueled Yoo-min's arousal, making him rougher. He gripped her slender, smooth thighs tighter and hammered his cock into her pussy even more savagely.
"Haaang... Please... Go easy... Ahhhut..."
"Call me... your Master..."
"Ahng... M-Master...?"
"That's right... When begging someone... show some sincerity..."
Suddenly, Yoo-min recalled their college days—how she'd dump all her assignments on him like it was his job, then turn away.
"Jiwon... You used to treat me like an idiot, didn't you?"
"N-No... Hngut... I didn't... Ahhng... I didn't..."
"What? You did. Dumping all your work on me... while you went off playing..."
"Hng... I'm... sorry. Back then... Hngg... I was immature... Ahk... Really... sorry... Haaang..."
"You still haven't learned... I told you, didn't I? If you want to ask someone for a favor... show sincerity... So from now on, call me Master..."
These weren't Yoo-min's true feelings. He'd long forgiven and forgotten those old grudges with Jiwon. But for some reason, he wanted to tease her—not out of hate, but because she was so adorably lovable. So he dredged up her black history, something he'd moved past but she still fretted over.
"M-Master... Hng... Master..."
"Good... From now on, I'm your Master."
"Y-Yes... Haaang... Master... Please... go easy... Haaang... just a bit... Haaang..."
That word "Master" from the once haughty, aloof Jiwon shattered Yoo-min's reason with excitement. He'd told her to show sincerity when begging, and she'd done so—calling him Master with formal speech. But he had no intention of granting her polite request. He kept pounding her roughly. Not satisfied, he pushed her bound ankles toward her lower belly, driving his cock even deeper and harder into her pussy.
Her plea for gentleness wasn't ironic sarcasm. Overwhelmed by surging pleasure, she truly felt like she might lose her mind.
"Aaaang... Haang... Master... Haaang... Please... Aaaaang..."
She climaxed again—who knew how many times now?—tears streaming from beneath the blindfold. Yet contrary to her ragged state, something deep inside her stirred, craving harder. Stronger.
Yoo-min had held back to savor the pleasure longer, but he'd reached his limit. He thrust deep to her womb walls and unleashed his ejaculation. The pent-up semen erupted with force enough to pierce them. Normally, he'd piston through for more rounds, but this single release left his body aflame, utterly spent. He pulled out of her pussy and collapsed onto the bed for a breather.
With his cock finally out, Jiwon could breathe properly again. She panted heavily.
"Haa... Haa... Haa..."
Yoo-min eyed her heaving breasts, then reached out to cup one in his palm. In his haste and arousal, he'd skipped them entirely. Now he kneaded her breasts carefully for the first time that day. They were the perfect size for one hand—smaller than Seohyeon's overflowing mega-tits or even Minseo's, despite her youth. But compared to them, yes; absolutely not small. They slightly overflowed his grasp, well above average. Bigger wasn't always better in shape, and Jiwon's modest size was shapely and beautiful. Perfectly rounded from base to nipple without gaps. Her slim, almost lean build made them stand out strikingly despite the size. Kneading them offered a different thrill from Seohyeon's soft, finger-sinking pillows.
Did his devoted massage help? Her ragged breaths steadied.
"Master... Kiss me, please."
Blindfolded, she turned toward him hesitantly, voicing her desire. Was this the first time she'd asked him for something herself? A sharp thrill shot through Yoo-min's chest at her words. He wanted to kiss her too. They both did—so why not? But he felt like teasing her more.
"How dare a slave demand something from her Master?"
"Am I... your slave...?"
"Obviously. You're Jiwon, servant to your Master—me."
"I see... Master. I'm sorry..."
"My lips are too good for a cheeky slave like you. Suck my cock instead."
"Th-Thank you... Master."
Yoo-min climbed atop her chest and brought his softening cock to her lips. She immediately stuck out her tongue and licked. Bound head to toe and blindfolded, she lapped at it like a lifeline. It responded quickly, hardening fully. He shoved it deep into her mouth—too deep, hitting her throat in his eagerness—but she sucked devotedly, ignoring the discomfort. Her earnest fellatio felt too good. He might cum in her mouth at this rate. But that would be a waste. The mission required two free ejaculations; cumming now would end it prematurely upon success. Gritting his teeth, he pulled out. He flipped her over, ass up, positioned behind, and thrust back into her pussy. Even after rest, it remained sopping wet.
With her wrists bound behind her back, she couldn't brace in doggy style. Each thrust sent her upper body flopping forward onto the bed unsupported. Her helpless form aroused Yoo-min further, and she thrilled at being used like a mere fucktoy.
"Ahuut... Aaah... Aaaang..."
It didn't take long for her to climax again. Feeling her walls clench hotly around him, Yoo-min's own release built. He'd forced back the first to prolong it, but this second followed naturally. Syncing with her peak, he buried deep and came. Fully spent, he withdrew. Her pussy gushed semen and juices in thick spurts.
Tch... Congratulations on clearing the mission. Participant Yoo-min and participant Jiwon each receive 10 points.
Paradise participants. Return to your private rooms immediately.
To dress, Yoo-min first untied her. He reclaimed his clothes from her wrists and ankles, then put them on. He dressed her in the pants used as blindfold and picked up her top from the floor, slipping it on her too. Even fully clothed, she leaned against him, body limp—strength not yet returned. Sighing, he supported her upright and headed to the square.
"Um... Master... Do I... have to keep using formal speech...?"
As they neared the square and spotted the group, she whispered hesitantly, dilemma clear in her voice. Intoxicated by rough sex, she'd called him Master formally, but continuing in front of everyone troubled her deeply. Yoo-min found her ridiculous yet endearing—cutely out of character.
"No, Jiwon. Treat me like before."
"R-Right... Yoo-min..."
"But you know, right? When it's just us, I'm your Master, and you're my slave."
"Yes... I know... Master..."
