I Tempt, But Can't Have Sex.

A grotesque yet brazen depiction of heat. 'This woman... whoever she is, she must have a ridiculously pretty face.' Just looking at it left me breathless. It wasn't merely the beauty of the female form. It was this bizarre thrill from discovering the artist's secret affair(?) all by myself.
'A young woman who shook up the artist who's spent his life gazing only at his wife. Who could she be? A university student? Or maybe a curator from an exhibition?' My dangerous imagination began to run wild.
'Professor, you must have gone all the way with her, right? How else could you paint a nude like that? Not just once or twice, but dozens of times, capturing that body with your eyes every single time.'
Does his wife know? What would she do if she found out?? Curiosity mingled with fear.
"It was a bit noisy during today's lesson."
"?!!"
A low, resonant voice. The professor spoke to me for the first time. Without even turning around, of course.
"Ah, uh... sir. I mean, Professor, sorry. Gwang-tae just has so much energy. Hehe~!"
My nape burned hot. It felt like I'd been caught peeking at the professor's secret.
But... a problem arose.
My body was already primed from Gwang-tae's earlier provocation. And now, imagining the hidden meaning(?) behind this overwhelming nude right in front of me had sent my 'female instincts' into full throttle.
Naturally, the spot between my legs throbbed again, leaking hot fluid. My panties were soaked through, making wet, sticky sounds.
"...Hm?"
The professor's nose let out a strange snort. His movements stopped. He set down his brush and slowly turned his body.
Thick glasses. Wrinkled forehead. It had been ages since I'd seen his face... Expressionless, but his eyes were sharp enough to pierce the canvas.
I could see his gaze slide past my flushed face to my thighs, trembling ever so slightly.
"No issue, then? Good. Gwang-tae's become so vigorous since turning adult. I was worried something might happen."
"No, he's fine. Gwang-tae talks big, but he's actually really sweet deep down. He's your son, after all."
"...I hope so. But if he ever loses control... I wonder if I'd have the strength to stop him."
"...??"
Is he saying Gwang-tae might rape me?? He's got the wrong idea about me. I'm not some pushover guy... er, girl, who gets taken advantage of easily by men.
"Teacher Yeon-woo. If you ever want to quit, just say the word anytime."
Fired?? Where am I supposed to find pay like this??
"Hehe... Gwang-tae~ As if he'd do anything crazy. Don't worry."
"Hm... I'd like to believe that. But desire has a way of turning people into fools sometimes. That's why the world is rife with crime."
"...."
The professor was giving me advice. But none of it registered. The scent wafting from between my legs grew thicker. The smell of a bitch in heat.
I tugged lightly at my short skirt hem. But it was no use. The fluid soaking my panties was ready to trickle down my thighs.
Damn... me and my excessive wetness. Too much, even for a woman like me.
Desire turns people into fools sometimes? Couldn't agree more. Maybe... I've already fallen into that state.
"You've changed your style of dress quite a bit."
"Huh?"
I'd always thought he was too absorbed in his work to notice someone like me.
"First time seeing you with makeup, too."
"Ha... ha... R-really? I do it pretty often usually?? Must've missed it? Hahaha~"
"No way you did..."
Truth is, the professor was right. I started wearing makeup purely because of... Christmas Eve. That day of madness. Ever since I tasted dopamine.
After that day, I've been exuding feminine allure, teasing men.
"Hm..."
The professor straightened his hunched back and approached me. He was a bit shorter than Gwang-tae, with endlessly sagging shoulders. The classic image of an 'impotent middle-aged man' came to mind.
"When a woman changes her outfits and starts dolling up, it usually means there's a man catching her eye, right?"
"...."
Truth is, I have a date with my 'boyfriend' after class. – A ridiculous excuse popped into my head.
But – I don't tell lies if I can help it – that's my creed.
"No man catching my eye yet... but I'd like one to appear. Hehe."
"...I see."
The professor was now right in front of me. His nostrils must have picked up the scent from down there... His gaze stared at my flushed face, then swept over my swollen breasts, and down to my skirt emitting that aroma.
Gaze-rape. Every time the professor's eyes touched my body, electric thrills shot through me.
His gaze finally shifted to the canvas in front of me. The one with the professor's 'new woman'.
"For a woman to feel something from my paintings... as an artist, that's a tremendous honor."
"?!!"
"Whether it's pure artistic appreciation or a primal, physical reaction."
He knew. He knew I was aroused... that my pussy was wet.
The professor's gaze returned to me. His tongue flicked out slightly.
My breath caught.

The next evening, I headed back to Woo Gwang-tae's house. Ragged T-shirt, knee-stretched jeans, messy hair hidden under a cap. ..That should've been enough.
But today, I lingered forever in front of my cousin sister's closet. I'd gotten permission ages ago to wear anything from her wardrobe, including what I wore on Christmas Eve.
In the end, my hand grabbed a dangerously short miniskirt that barely reached mid-thigh. Paired with a knit top that gaped loosely at the cleavage.
'I'm losing it, Kang Yeon-woo. Am I heading out to tutor or hit up a Gangnam club?'
In the mirror, I looked like I was straight-up advertising 'Come get me, boys~'.
That cheeky bastard. Woo Gwang-tae. His eyes scanning my breasts while offering double pay wouldn't leave my mind.
That vulgar, beastly gaze. Just recalling it made my nipples stiffen.
Kept me up all night because of it.
-Ding-dong.
The door flew open the moment I rang. Like he'd been waiting.
"Teacher, you... H-huh?!"
Gwang-tae's eyes nearly popped out. Thick winter coat covering me head to toe. But underneath? Pure summer.
He gawked, mouth agape, eyes blatantly raking from my collarbone down the deep cleavage, smooth thighs, all the way to my shoe tips.
"Whoa... Teacher.."

"Wh-what?"
"N-nothing."
Gwang-tae's face flushed beet red in an instant. I'd gone all out today, head to toe.
His Adam's apple bobbed hard. Looked ready to bolt to the bathroom and jerk off.
His reaction brought an involuntary smile. I was pleased.
"Teacher. Yesterday you were all 'I don't like you,' pushing me away cold. Today you're dead serious, huh? Wow, this is straight-up 'Gwang-tae, what're you waiting for to devour me?' vibes. Style's insane."
"Hey, Woo Gwang-tae! Shut it~ Stop yapping and let me in!"
I stomped in extra pouty. The vast garden was blanketed in soft white snow. Snow absorbs sound. Any screams from inside the house would be swallowed whole.
'Wh... what the hell. That's not why I came...'
The living room was quiet again today. Gwang-tae's mom – the wife – was absent as usual.
"Wife not home again? She's been busy."
"Mom? She's at her student's recital again. Dad's out drinking with old friends for the first time in ages, coming back late.."
"Ah... I see?"
"Why~ Teacher? Why~ Teacher? Knowing it's just us two got you all excited~?"
Gwang-tae grinned stickily, pressing right up behind me. His hot breath on my nape raised goosebumps.
"Teacher said it already! I'm taekwondo red belt!! Keep messing around and you're in real trouble!"
I shoved him away yelling louder on purpose. But Gwang-tae just looked at my resistance like it was cute.
...Well. I didn't hate it.
The lesson began. Today's topic: Fundamental Theorem of Calculus.
But right now, in this room, nothing was fundamental. Starting with my emotions.
"So, differentiation finds the 'slope, or rate of change,' and integration finds the 'area, or total accumulation,' but.."
My voice trembled. Gwang-tae, sitting beside me, wasn't looking at the workbook. His eyes were fixed on my top, right where my nipples poked out.
'I'm insane. Even if Gwang-tae forces himself on me now, I couldn't complain.'
No bra. Just thin knit fabric. My stiff nipples traced slutty lines, faintly visible.
And not just nipples? A little movement and my breasts jiggled.
-Slosh~ Slosh~!!
Even from 100 meters away, it'd scream, I'm braless right now!!
'I really am crazy. Acting like this in front of my young student?'
But against my rational mind, my body was drinking in the thrilling pleasure from Gwang-tae's lecherous stare.
A week's worth of masturbation material. Hell, maybe a month's fantasies of this moment.
"Teacher..."
Gwang-tae's voice dripped with lust. Past erection – now leaking precum territory.
"So, Gwang-tae. This differential coefficient means the slope of the tangent line at a point on the curve..."
"Teacher.. I don't get this part. Can you explain once more.."
Pretending to ask, Gwang-tae scooted right up against me. Whoosh – his musky scent invaded. Young stud heat mixed with semen smell tickled my nose.
-Thud.
"?!!!"
His elbow brushed my side boob. A split-second contact, but that soft, heavy friction dropped my heart.
Deliberate touch... His arm kept stroking up and down my side breast, regardless of where his hand pointed on the problem.
Tasting... my tits.
"Y-yeah.. Th-this problem is.. ab-about.."
My breathing quickened. Even as my breast was being raped, I didn't resist – just kept explaining calculus.
