Chapter 11 - Engineering Goddess Lee Jieun, Anal Fingering (1)
"You have to go out on a date?"
A decent franchise cafe in front of the school. The classmate sitting across from her asked with wide eyes.
"Didn't you say you had a presentation today? But you're going out on a date?"
"Ah, that? It's fine. The oppa in my group agreed to do it for me."
Lee Jieun answered nonchalantly, using her phone screen as a mirror to fix her bangs.
At that carefree attitude, the classmate let out a dry laugh as if dumbfounded.
"Wow, Lee Jieun. You really have no conscience. You're going to be in big trouble later."
"What's with the 'conscience' talk over something like this? Everyone gives and takes this much. I'll pay him back later."
"You have a boyfriend, so doesn't he say anything when you use another guy like that?"
"Forget it, why are you talking about such useless things."
Lee Jieun waved her hand dismissively and changed the subject.
She brushed it off in front of her classmate, but in Jieun's mind, the importance of her boyfriend had hit rock bottom a long time ago.
He's a guy who goes to a different university and doesn't even have much time to meet lately.
He's just a fashion item good for showing off, a wallet that pays for date expenses; that's exactly the level he's at.
Honestly speaking, it wouldn't be strange if they broke up at any time. Her boyfriend might think differently, but that's how Lee Jieun treated him.
-Buzz.
Phone vibration. It's Lee Jieun's boyfriend.
"Oh, oppa. Yeah, I was waiting just now. Okay. I'll head out."
She eats a decent meal with her boyfriend she hasn't seen in a while, drinks coffee, and naturally heads to a motel. It's a cliché, boring date course pattern that happens about twice a month.
"Haa... Ji, Jieun-ah..."
"Aaat, oppa, h-how is it?"
"Kk... Jieun-ah, ah, I think I'm gonna cum...!"
The boyfriend clings to Jieun a few times, then Jieun jerks him off with her hand.
-Splurt.
Lukewarm liquid splattered. Jieun forced the corners of her mouth up to smile.
"Whew... Jieun-ah, that was so good. I'm going to go wash up first."
Watching his back as he grabbed a towel and entered the bathroom, the smile was completely wiped from Jieun's face.
"Haa..."
-Swishhh.
The sound of the shower came from beyond the bathroom door. Even humming. It's the sound of her boyfriend washing up happily after satisfying his urges.
"Haa... seriously..."
Left alone on the bed, Lee Jieun, unlike her boyfriend, was in a bad mood.
Jieun had been to a motel with her boyfriend several times, but she had never been aroused once.
It's not that Jieun has no sexual desire.
It's just that her boyfriend's foreplay wasn't satisfying.
In the end, before they could even get to sex, Jieun would satisfy her boyfriend with her hand first, and it seemed like the boyfriend was satisfied with this relationship ever since.
Jieun was still a virgin.
"Pathetic..."
Jieun pulled the blanket over her head and slipped her hand between her legs.
The first thing she touched was a lukewarm, sticky sensation.
Despite her boyfriend's pathetic foreplay, her pussy was aroused all on its own.
'Haa... we didn't even really do anything... why is it so wet.'
The tension of not knowing when the bathroom door would open. The shame of having to finger herself. That strange sense of immorality made Jieun even more aroused.
"Huu, whew."
The air inside the blanket grew hot from her rough breathing. Jieun scraped up the mucus from the sticky pussy entrance and coated her middle and index fingers generously.
She pressed down hard on her swollen clitoris with her slippery fingers.
"Hng... ugh..."
-Squish.
"Aah... haa, ah..."
As she rolled the bean up and down, clear love juice gushed out from between her pussy lips.
Jieun twisted her waist and brought her other hand up. She pinched and twisted her sharply erect nipples.
-Squish, squish!
The sound of mucous membranes being crushed below, and the pleasure of her nipples being rubbed above, struck her brain.
Precise stimulation that couldn't be compared to her boyfriend's impatient touch.
Her hips lifted, and the speed of her fingers moving became faster and faster.
"Haang, hng... there, mmm... haa... aah."
Her eyes unfocused, and sweet pleasure ran down her spine.
"Ah......"
But only up to there.
No matter how much she crushed her clit and twisted her breasts, the empty sensation in her lower abdomen wasn't filled.
Friction that only licked the surface shallowly.
Her pussy was crying out for thirst with its mouth open, but Jieun's fingers could never fill it.
'It's not enough... not this ticklish stuff. Ugh...!'
The fingers rubbing her clitoris paused. Jieun groped with her fingers toward her pussy, where love juice was stretching like spiderwebs.
"Huu, no... I'm going crazy..."
Just rubbing her clitoris wasn't enough. Jieun placed two fingers right at the entrance of her pussy, which was glistening with love juice.
It was slippery, mixed with sticky pussy juice. The narrow vaginal opening swallowed her fingers without a single moment of resistance.
-Squish.
"Aah... haaaa...."
The hot, damp inner walls bit down on her fingers. The highly aroused mucous membranes sucked on her fingers and stuck to them stickily.
The sticky vaginal flesh sucked and wrapped around her fingers with a slurping sound. Jieun stirred her fingers roughly, scratching hard against the bumpy vaginal wall folds.
-Squish.
"Th-this is... haa, inside... ugh."
Her pussy twitched as if chewing on her fingers, and every time she thrust, clear liquid gushed out from deep inside.
Every time she dug her fingers in, a tingling pleasure sprang up from deep in her pubic bone.
But Jieun soon furrowed her brows.
'No... this kind of thing isn't enough....'
Two fingers were woefully insufficient.
She desperately needed something thick that would push in ignorantly as if to tear her narrow pussy apart and expand it until it felt like it would burst inside.
She had seen her boyfriend's thing a few times, so it was obvious. Knowing full well that she wouldn't be satisfied with his thing, Jieun had gone out of her way to satisfy him with her hand.
"Huk, just a little, ugh... just a little deeper inside..."
Aroused by the emptiness, Jieun twisted her waist and angled her fingers wildly.
The moment she forced her hand toward a deeper, unfamiliar place that she usually couldn't even reach.
-Plop!
"Aah...?"
Her fingers, which had slipped on the pooled love juice, popped out of her gaping pussy.
And they roughly brushed past the taut perineum between the vaginal entrance and the anus.
At that moment.
"Hiiik...?!"
Jieun's waist jumped up on the bed.

It's different from the sweet pleasure of thrusting inside her pussy. A thrill that felt like a needle piercing through her spine and directly into her brain struck her whole body.
"Hup, huuk...! Ugh, ugh...!"
Just a single friction.
The fine hairs around her back hole, which she had never used in her life, stood straight up. The tip of her urethra tingled, and her entire lower abdomen went numb as if it had a cramp.
"Aahk, ack, ugh......!"
Her pussy lips were startled and trembled. Even the small anal folds that had been tightly closed were gaping open regardless of her will.
A dizzying sensation like she was about to pee. If she pressed just one more time on that area near her back hole that she had just brushed against...
'If I touch here... no, I can't......'
Jieun was scared. It felt like she had crossed a line she shouldn't have.

"Ha, ah... huugh..."
Fearing that she had become a pervert, Jieun was startled and hurriedly pulled her wet fingers out from between her legs.
Her heart was pounding as if it would burst, and her body wouldn't calm down easily.
"Ah, annoying... I can't cum like this...."
No matter how much she thrust and rubbed, it was only up to there. The threshold of true pleasure didn't open.
Jieun eventually pulled her hand out nervously. She just panted roughly, holding up her fingers sticky with love juice.
It was always like this.
Jieun had never felt a 'true orgasm' that made her vision go white. Always just a sticky, frustrating thirst as if something was blocked somewhere.
The unresolved, sticky desire turned into annoyance and welled up.
"......"
Suddenly, the face of a man popped up.
The face of Han Junyoung, who used to look at her indifferently.
'...Was I too much?'
The words her classmate had carelessly thrown about her having no conscience lingered in her ears. If it were usual, she would have snorted and brushed it off. Strangely, her heart was pounding.
The tasks she had passed off to Junyoung one by one flashed by.
At first, light research. Then, PPT creation, and yesterday, script organization. Finally, today, she had dumped the entire presentation on him with the excuse that her grandfather was sick.
'No, he's the one who accepted everything like a pushover, so why am I like this...?'
Even while rationalizing it in her head, a strange sense of debt and apology wouldn't easily subside.
"......"
Jieun picked up her phone by the head of the bed as if possessed. She opened the messenger with her fingers, which were slippery with pussy juice.
Tap. Tap-tap.
[ Junyoung-ssi, actually, they said my grandfather is better. My trip down to the countryside was canceled.]
[I'm so sorry for delaying the presentation today ㅠㅠ Can I at least buy you a meal? ]
Sent. Jieun stared blankly at the screen where the number 1 was displayed.

When she came to her senses, Lee Jieun was sitting on the floor of her studio apartment.
Legs stretched out under a short skirt. And sitting across from her was Han Junyoung, whom she had just eaten with.
'Why... am I doing this?'
She looked at the empty soju bottle with dazed eyes. She definitely intended to just eat and part ways.
When she came to her senses, she had dragged him into her studio apartment.
'Why did I... call him to my place?'
Jieun looked back and forth between the half-empty soju bottle and Han Junyoung sitting across from her with dazed eyes.
She didn't black out.
She had a light drink while eating.
Then, suddenly, her sorrow burst out, and she poured out complaints about her life without being asked. Han Junyoung silently listened to all that pathetic drunken rambling.
And Lee Jieun grabbed Han Junyoung.
'Let's have one more drink. At my place.'
Crazy bitch. Bringing another man into her studio apartment when she has a boyfriend. Lee Jieun also had a normal level of chastity.
But......
'Why did I do that?'
She couldn't know the reason. However, it was certain that Han Junyoung felt strangely comfortable.
-Click.
Jieun put down the empty glass and moistened her reddened lips.
Is it because of the alcohol? Or is it because the heat from when she was thrusting alone under the motel blanket earlier hasn't faded yet? Her fair cheeks were flushed to the fullest.
Slightly unfocused, wet eyes.
Lee Jieun's face was completely devoid of wariness.

To be honest, I'm also bewildered as to why I'm sitting in Lee Jieun's studio apartment right now.
I didn't step up and suggest doing anything first.
I didn't even think about casting some grand hypnosis or brainwashing. I just scribbled down the annoyance I usually felt toward Lee Jieun.
[ Lee Jieun should stop dumping her work and learn to be grateful.]
When that one line went through the app, the text appeared refined.
[ Lee Jieun feels deep gratitude and indebtedness for Han Junyoung's help. ]
[ Lee Jieun confides in Han Junyoung about worries she can't tell others. ]
[ Lee Jieun does not doubt Han Junyoung's help. ]
[ Lee Jieun does not speak of her business with Han Junyoung. ]
"...This actually works."
A dry laugh leaked out.
That's not the only problem.
As soon as I registered Lee Jieun, this crazy app added functions to my existing skills as a "special perk" on its own.
"Jun, Junyoung-ssi...?"
Lee Jieun, who had downed the remaining soju from across from me, opened her mouth with a flushed face.
"Junyoung-ssi? Um... can you give me some advice about my boyfriend? Since you're a guy too... I feel like you'd know better."
"Why? Is something wrong?"
'Why are you talking to me about your boyfriend.'
I don't know why she's asking for boyfriend advice.
But it's not like I don't have a guess.
[ ▼ Satisfaction ]
[ Overall Satisfaction: 5% ]
[ Sex Satisfaction: 0% ]
[ Orgasm Satisfaction: 5% ]
[ Kink Satisfaction: 0% ]
A bitch who has never felt it properly even once on a bed. A bitch with even a unique kink. Anal and NTR, of all things.
"Where is it not matching up?"
"Ah, that, ah...... so..."
Hesitating, Lee Jieun picked up the soju bottle instead of answering, poured it into her glass, and gulped it down in one go.
-Clack.
"Junyoung-ssii......"

Lee Jieun looked at me pitifully with unfocused eyes and made a nasal sound.
Looking at Lee Jieun, I activated the additional function of 'Clean' that was given as a special perk this time.
[ Unlock Option: Internal Cleaning ]
[ Perfectly disinfects and removes residual foreign substances from the target's vagina and rectum (anal). ]
