The Marker That Stirred Her Pussy Returns to Min-gyu's Hands

"Recording's done, Master. I need to get back to class now."

Song Jiwon ended the video and set her phone down. Her face in the mirror was flushed with heat, strands of disheveled hair clinging to her cheeks as they trembled with each breath.

'What the hell did I just do...'

'I really need to stop this...'

She bit her lip and lowered her head, but her eyes remained bloodshot. The desire-drenched gaze refused to fade. Leaning against the wall, she lifted her skirt slightly and adjusted her panties.

'Ah... it's completely ruined...'

Her once-white panties were soaked through with her juices. The center had turned almost transparent, and the faint, lewd scent rising from her pussy filled the cramped restroom.

She carefully pressed her fingers against the fabric. The sticky sensation clung to her fingertips, and when she pulled away, a thin string of arousal stretched between them.

'Going back to class like this...? I must be insane...'

There was no time to change. She pulled on her stockings, the nylon sliding up her legs and pressing the damp panties tighter against her skin. The sensation only made her more sensitive.

After straightening her blouse, she looked at herself in the mirror again. Deep cleavage peeked through the open buttons, the outline of her black lace bra barely visible. Her E-cup breasts strained against the fabric, threatening to spill out. She undid one more button. The fuller curves became even more exposed, and the reflection staring back at her felt unfamiliar.

Caught between sexiness and shame, she eventually smiled.

'I don't want to hide anymore. I've already become his bitch...'

She smoothed her skirt one last time and examined herself. The tight black skirt ended nineteen centimeters above her knees—any slight bend would reveal her panty line. The stockings clung smoothly to her legs, the nylon sliding over her damp panties and making her shiver again.

She ran her fingertips slowly over the stockings. The soft nylon made it feel as if someone were caressing her thighs.

'Once I walk into the classroom... everyone will see me. But no one will know what I just did. I'm dressed, yet I feel completely naked...'

'The students will just see their teacher, but I'm the bitch who just masturbated with a student's marker...'

The thought made her pussy twitch. Her panties were still wet, the clinging fabric stimulating her further. She applied fresh lipstick to her slightly swollen lips—swollen from sucking on the marker earlier—then spritzed perfume on her wrists and neck. The sweet, heavy scent wrapped around her body.

She picked up the marker again. Traces of her juices had dried faintly on the surface, the tip still damp. Pressing her fingertip against it sent a clear jolt through her core.

'This was inside me just moments ago...'

Staring blankly at it, she remembered she had to return it to Kim Mingyu.

'I have to give this to that gloomy Kim Mingyu...'

A strange bitterness welled up. That quiet, unremarkable boy would never imagine the marker had been inside her pussy and mouth.

'Every time he puts it in his mouth or touches it... it's like he's indirectly touching me...'

The thought made her crotch throb again. She pictured the marker sliding between his lips, and her insides began to pulse once more.

'Well... someone like Kim Mingyu will probably never even hold a woman's hand in his life. Consider it a small reward.'

Smirking, she placed the marker—still unwiped—into her bag. Then she opened the video she had just recorded. On screen, she was spreading her legs and pushing the marker into her pussy. Wet, sticky sounds accompanied the sight of her glistening folds and swollen clit.

"Ah... the student's marker is... inside my pussy..."

The voice on the video was nothing like a proper teacher's. It was the lewd, desperate moan of a bitch consumed by lust. Watching herself, Song Jiwon felt her face burn. At the same time, fresh arousal seeped into her panties. Seeing her own pussy swallowing and expelling the marker, dripping with juices, aroused her all over again.

"Ah... ah... Master... I'm... about to come..."

At the peak, her body trembled violently as she squirted. Her juices sprayed out like a fountain, her pussy clenching and spasming around the marker until the fluids ran down to her ass. The sound of droplets hitting the toilet bowl only made it feel more obscene.

'Do I really have to send this...? If I send something like this... does that mean I'm truly his bitch now...?'

She hesitated for a long time, her finger trembling over the send button. Eventually, she began lying to herself.

'My face isn't showing. There are plenty of women with big breasts besides me...'

Anxiety and excitement boiled inside her chest. She imagined her master masturbating while watching the video.

'Master coming while looking at my pussy... Just thinking about it... makes me wet again... ah...'

Her panties were already soaked once more, her ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠nipples stiff. She could no longer hold back. Song Jiwon pressed the send button firmly.

Just then, she ran into physics teacher Lee Hyun-woo at the end of the hallway. Lee Hyun-woo, in his mid-thirties, was one of the most popular teachers in school, especially among the female students for his tall stature and broad shoulders. He approached with a gentle smile.

"Ah, Ms. Song. Where have you been?"

In that moment, Song Jiwon became acutely aware of her appearance: the deep cleavage visible through her open buttons, the skirt so short that her mesh panties could show with the slightest carelessness, and the faint outline of her nipples pressing against her blouse.

She tried to straighten her posture, but Lee Hyun-woo's gaze was already slowly sweeping over her body—tracing her neckline, lingering on her cleavage, then sliding down her waist to her skirt hem and the thighs above her stockings. His look was unmistakable. He was seeing her sexually.

Feeling that gaze, she felt a strange excitement stir instead of discomfort.

"Ah, I just went to the restroom."

She answered with the most natural smile she could manage. Her face was still flushed, her lips plump and glossy from sucking the marker earlier, the lipstick slightly smeared.

"Are you all right? Your face looks a bit red."

Lee Hyun-woo spoke with concern, but his eyes remained fixed below her neckline.

"I'm fine. It's just a little warm."

As she replied, she unconsciously pushed her chest out a little more. With each breath, her nipples brushed against the bra and blouse, growing harder. She noticed she was enjoying the sensation—because her body was still aroused.

Lee Hyun-woo lowered his gaze naturally while pretending to worry. His eyes paused on the cleavage visible through her open buttons, the look unintentionally stimulating her. She forced a smile and looked away, yet she knew exactly where he was staring and unconsciously pushed her chest out even further. Her nipples remained stiff beneath the fabric, her breasts straining against the blouse with every breath. A thrilling shiver ran down her spine each time the material brushed them.

Lee Hyun-woo's gaze continued downward—from her chest to her narrow waist, then to the smooth thighs beneath her short skirt. His desire was no longer hidden. She could feel it clearly. He smiled softly again.

"Well then, teach your class well. See you later."

"Yes, see you later."

Song Jiwon answered briefly and turned away. She could feel his eyes fixed on her ass as she walked. The gaze felt strangely warm, and oddly, she didn't find it unpleasant. Instead, a light excitement bloomed. She deliberately swayed her hips a little more with each step. The click of her high heels echoed down the hallway like background music to her arousal. Her stocking-clad legs moved rhythmically beneath the miniskirt, as if she were walking to be admired.

'Did he notice what I just did? If he knew I fucked myself with a student's marker... if he found out my panties are wet... Or what if I had used Mr. Hyun-woo's cock instead...'

The fantasy grew dirtier and more stimulating, making her insides throb again. Using Min-gyu's marker suddenly felt regrettable. It had been too small and thin to satisfy her.

Reaching the classroom door, she paused to ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠take a deep breath and check her clothes. Then she realized—the outfit had never been "proper" to begin with. The loose blouse, the tiny skirt, the smooth bare legs beneath... She swallowed a quiet laugh.

'Anyway... this is who I am now. It's fine like this.'

The thought eased her tension. She opened the door lightly.

"Sorry, everyone~ I'm back."

All eyes turned to her. She naturally shifted her gaze to the center of the classroom—Kim Mingyu, still quietly drawing. When he looked up at the sound of the door, he stared at her for a long moment. His gaze slowly traveled from the cleavage between her buttons down to her thighs beneath the skirt.

Song Jiwon's heart pounded.

'Stay calm. Min-gyu doesn't know anything. He can't possibly imagine what I just did with that marker...'

She walked toward the podium, conscious of his stare. Carefully, she took the marker from her bag—the object that might still carry the faint scent of her juices. Approaching his desk, she spoke.

"Min-gyu, thanks to your marker, I... used it well. Thank you."

She added with a slight smile, "The grip felt... really smooth..."

The words slipped ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠out before she realized it. Flustered, she quickly set the marker on his desk. Her fingers trembled, and a strange fluttering filled her chest. Worried he might smell it, she unconsciously pressed her hand against her thigh.

Kim Mingyu accepted the marker casually. "Yes, teacher. No problem."

His voice was as quiet and indifferent as ever. He placed the marker on his desk and returned to his canvas as if nothing had happened. Song Jiwon paused, surprised. She had expected some reaction, some sign of suspicion. Had she been hoping for that?

'What was I expecting... There's no way this kid could guess the marker was inside my pussy and mouth...'

She forced herself to look away and continue the lesson, but her eyes kept drifting back to him. He painted silently, occasionally putting the marker in his mouth. Watching that, her throat went dry. She gulped water, but the heat between her legs refused to fade.

'He didn't wipe it... so right now he's putting the taste of my pussy straight into his mouth...'

Just the thought made her pussy itch. She unconsciously crossed her legs to suppress the sensation. Kim Mingyu had always been an unremarkable student—quiet, ordinary, not particularly masculine. But knowing that the very marker now between his lips had just been stirring inside her filled her with an inexplicable desire.

'Why am I like this... Min-gyu is just... Min-gyu...'

Her body was already reacting. Her panties were growing wet again.

"All right, everyone. Please finish up your pieces. You can work freely for the remaining time."

Her voice was slightly higher than usual. She tried to hide the tremor, but her heart raced faster with every step she took around the classroom. Checking students' work, she finally arrived at Kim Mingyu's desk. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠The moment she looked down at his canvas, her heart seemed to stop.

He was drawing a nude woman. The face was omitted, but the body... was identical to hers. Full breasts, a narrow waist, a round and firm ass. Even the pose—one hand squeezing her breast—matched the photo she had sent to her master the day before.

'...No way. This must just be a coincidence...'

Cold sweat ran down her spine. She looked at Kim Mingyu cautiously.

'Could Min-gyu be MasterOfBitches69...? No. That's impossible. A timid kid like him couldn't be that. It's... just a coincidence.'

Convincing herself, she steadied her breathing and spoke with feigned composure.

"Min-gyu, this drawing is... quite..."

At that moment, Kim Mingyu slowly removed the marker from his mouth. His eyes held something indescribable, piercing through her with quiet intensity. Then he spoke.

"Teacher, this marker... smells kind of strange. Almost like perfume... but oddly strong."

Song Jiwon's heart dropped. Her face froze in shock, unable to form a reply.
