The Convenience Store Girl (3)
The sound of hot water crashing against the shower room tiles was deafening.
As the stream poured over his body, sticky with sweat and semen, the feverish heat from their intense lovemaking began to fade, and his clouded reason slowly returned.
"Hiiing... Oppa, how much did you cum? It's coming out endlessly."
Seonwoo gazed at Yuri's back as she whined petulantly while spreading her pussy wide to scoop out the semen. Her white back, slender waist, and voluptuous hips formed a curve like a work of art.
And the evidence he'd left on her body—the handprints on her porcelain-like ass, the semen dripping between her thighs, and her long, sweat-matted hair clinging to her back—was so erotic that no man could resist.
As he watched Yuri's lewd washing motions, a lightning bolt of an idea flashed through Seonwoo's mind.
'10-Min Preview... It's not just for coins, is it?'
Until now, Seonwoo had only used the skill to make money. But its essence was seeing the future. Couldn't it be applied to situations like sex just as easily?
He might even find a way to turn this woman, Yoo Sori, into a perfect bitch in heat.
Seonwoo immediately opened his Status Window. A new system message blinked that he hadn't noticed before—probably overlooked in the heat of sex.
Congratulations on your first 10 million won stat purchase! As a commemorative benefit, a skill upgrade is provided.
The '10-Min Preview' skill has evolved into '10-Min Blackbox'.
"10-Min Blackbox…?"
Seonwoo checked the skill description as if entranced.
You can view the next 10 minutes of the future like a video. (Fast-forward, rewind, pause possible)
The 'Blackbox' video automatically updates in real-time to the most likely future based on changes in the user's intended actions.
"Fuck, this is insane..."
Seonwoo muttered without realizing it. This wasn't just an upgrade.
It was worlds apart from the old Preview, which only showed the 'result' 10 minutes ahead. Now he could watch the entire 'process' like a video, and it even changed based on his thoughts. It was practically precognition. A godlike omnipotence sent chills down his spine.
As he grinned excitedly to himself, Yuri turned her head and asked,
"Oppa, what's got you so happy? You're suddenly laughing alone..."
"Nah, nothing. Just loving showering with you."
Seonwoo brushed it off casually, wrapping his arms around Yuri's waist. Then he immediately activated the 10-Min Blackbox.
'Show me the future where I fuck Yuri the most intensely for the next 10 minutes.'
A video of the shower room played rapidly before his eyes. He and Yuri tangled in various positions flashed by.
The desire every man dreams of at least once—driving a woman to endless orgasms. Seonwoo imagined various plays in his head, editing the video's future.
Grabbing Yuri's hair and pounding her. Pinning her against the wall and lifting her leg. In the video, Yuri screamed in pleasure, but Seonwoo wasn't satisfied. He needed more—overwhelming ecstasy to completely shatter her mind.
Then the video paused on one scene. As he lightly choked Yuri's neck, her pussy clenched like a spasm, and a beastly moan burst from her mouth.
'Fuck, that's it.'
Seonwoo smirked wickedly. He approached Yuri from behind as she was lost in thought, pressing his wet body against hers.
"Yuri."
"Y-Yes, Oppa...?"
Instead of answering, he rubbed his rock-hard cock between her ass cheeks, bending her waist and sliding in. Standing doggy style.
"Hngh! So sudden...!"
Yuri braced against the wall in surprise at the abrupt insertion but soon twisted her waist slightly, accepting the overwhelming size filling her depths.
Seonwoo grabbed her F-cup tits roughly from behind with one hand, wrapping the other lightly around her neck. Then he thrust his hips hard. The wet slapping of flesh echoed through the shower room.
"Haah! Ah! Aang! Oppa, too, too deep! Ungh!"
At that moment, Seonwoo tightened his grip on her neck just a bit.
"Ghk...!"
Exactly like in the Blackbox. Yuri's pussy clamped down hard, contracting like a living creature trying to devour his cock. Breathless with ecstasy, she stuck out her tongue long and rolled her eyes back.
"Keh, kehk...! Uguuuuh! H-Hek!"
Startled by the vulgar sounds coming from her own body, Yuri panicked, but Seonwoo just smiled in satisfaction. He adjusted the pressure on her neck, finding the exact intensity that made her most sensitive.
"Yuri. You know I booked unlimited free shots, right?"
Seonwoo wiped down Yuri's trembling body, still quivering from the aftershocks of climax, with a towel. Then he scooped her up effortlessly in a princess carry.
"O-Oppa...? Wait, just... calm down a bit..."
Yuri swallowed hard, recalling the near-fainting orgasm she'd just experienced for the first time in her life. Her voice trembled with fear and anticipation.
But Seonwoo ignored her, heading straight for the bed. As soon as he laid her down, he aligned his still-erect cock between her legs.
"Hiiiik...! Oppa, it's even bigger than before..."
Before Yuri could finish, Seonwoo mounted her in missionary, gripping her white neck with both hands and pistoning roughly.
"Eup! Ueup! K-Kekh!"
The massive orgasm crashed over her again, leaving Yuri unable to even resist. Her pussy squirted like a fountain, eyes rolling back as she let out incomprehensible moans.
"Ogooooh!! Hue... Uguuuh...!! S-Save, me...!"
Even as Yuri climaxed, Seonwoo held back. He kept up the merciless pistoning on her writhing body amid the waves of orgasm.
"Oppa!! Yuri's, g-gonna break!!"
With that final cry, Yuri couldn't withstand the continuous climaxes. Her eyes rolled back, and she passed out completely.
The instant Yuri lost consciousness, Seonwoo unleashed his hot semen deep into her womb.
Seonwoo looked down at her limp body—slack form, unfocused eyes, face covered in traces of pleasure. He let out a satisfied sigh, pulling out his still-hot cock and cumming once more inside her unconscious pussy, then once on her innocent face.
As he meticulously cleaned Yuri's body with wet wipes, Seonwoo pondered.
'10-Min Blackbox... This is a total cheat skill.'
During sex, he could pinpoint exactly where his partner felt the most pleasure.
And for coin trading? Not just simple rise/fall predictions—he could watch the full 10-minute flow and nail the optimal buy/sell timings.
His chest swelled with anticipation of earning amounts incomparable to the old 10-Min Preview days.
About 30 minutes later.
"Ung..."
Yuri opened her eyes with a small moan. Her gaze naturally drifted to Seonwoo's lower body. Seeing it still erect, she freaked out and yelled,
"Hiiik...! Oppa, I can't do more!! Please forgive me!!"
Seonwoo chuckled lightly at her reaction.
"I can't either. Don't freak out."
Relieved, Yuri sighed and smiled cutely.
"Phew... I really thought I'd die from sex."
She pulled the blanket over herself and grumbled.
"I never knew I had a kink for that kind of play. I thought rough stuff was just a sex fantasy, but choking... I couldn't even imagine it. But... it felt so good, weirdly."
Seonwoo found her adorable. He kissed her forehead lightly and said,
"I'll book you again next time."
Yuri's face lit up brightly, then dimmed a bit.
"Hiiing..."
After pouting briefly, she entered her personal number into Seonwoo's phone and said,
"Next time, no booking—just date me. I wanna fuck you more, Oppa. You have to text me, okay?"
They shared a quick peck and left the room.
Back home, lying on his bed, Seonwoo replayed their intense session. Then his phone buzzed briefly.
Seonwoo murmured softly at the message.
"Cute."
With a satisfied smile, he drifted off, happily imagining how much money he'd make tomorrow using the 10-Min Blackbox.
