The Teacher's Cowgirl Sexual Relief
Slurp.
Seol noona’s lips clung to the tip of my glans as if she meant to suck out every last drop, making soft wet sounds as she did. She held the twitching head of my cock in her mouth for a long while after I came, then finally pulled away with a reluctant little sigh.
“Haa…”
Gulp.
Her throat bobbed as she swallowed every trace of me. Not a single smear lingered at the corners of her mouth—as if the blowjob had never even happened. A flawless, tidy service.
“Shall we start the real sexual relief now?”
She rose from her seat, the usual gentle, soft smile replaced by something sultry and leisurely.
“Sexual relief… sex.”
Her hands went to the buttons of her formal jacket. In the quiet room the soft click of each button coming undone rang out clearly.
The jacket slid from her shoulders. Beneath it a white blouse clung to the curves of her body. Without taking her eyes off me she began undoing the blouse buttons one by one from the top.
The first button freed the smooth line of her collarbones. The second revealed the upper edge of a plain gray bra and the dizzying valley of her cleavage.
With every layer that fell away, the composed teacher’s mask crumbled. What lay beneath felt like the true face of a wanton female animal.
She tossed the blouse aside completely and reached for the zipper of her tight pencil skirt. As the zipper parted the skirt peeled away from her underwear, revealing the matching gray panties that had been hidden underneath.
“Whoa…”
The admiring sound slipped out of me unbidden. Plain, ordinary gray lingerie—yet somehow it carried a mature allure utterly different from a college girl’s. That only made her body radiate an even more unbearable eroticism. The center of her panties was already dark and soaked through.
She must have been just as worked up as I was during the blowjob.
“I can’t make a man wear himself out rocking his hips.”
Still in nothing but her underwear, Seol noona came toward me. She spread her legs on either side of my thighs and settled herself above my cock.
“I’ll take care of everything.”
She rested her hands on my shoulders and slowly lowered her hips. Afraid she might still try some secret male-teasing technique, I lightly caught her waist. Right now I needed sex more than foreplay.
“Let’s skip the preliminaries. I want to fuck you right this second.”
At my words she smiled as if delighted and nodded.
“Okay. Whatever you want.”
At last that hot, dripping heat began to swallow my cock.

Schlick!
“Huu…”
A thrilling sensation wrapped my entire body, as if I had been walking through a desert for days and finally drunk from an oasis. The moment the tip of my glans touched her wet entrance my mind went hazy.
The raw feel of her pussy. Seol noona’s inner walls were tight, yet at the same time incredibly soft. Because she was already drenched there was almost no dryness or friction. Slippery love juice coated her flesh as it twitched and pulled me in like a welcome.
“Hnn…!”
A short moan burst from her lips. At the same instant her pussy clenched hard around my cock. Every time the head forced its way deeper, soft folds coiled around me as if determined never to let go.
“Your pussy’s fucking tight, noona…”
Seol noona’s cunt was even better than I had imagined. I had to admit I had gotten a little complacent after fucking her once already. Last time I had finished so fast I had underestimated her, but taking it slow like this—her pussy was no joke.
“Hnn, hah… it isn’t even all the way in yet, ahh, nn, why are you acting like that…?”
Even as she said it her voice was already soaked with pleasure. Finally my cock seated itself to the root inside her. Hot, soft, narrow, ridged, and wet—her flesh wrapped every inch of me without a single gap.
“Haa… how does my pussy feel…?”
“Fucking amazing…”
Seol noona took me to the hilt and let out a satisfied sigh. Then she began moving her hips in earnest. She was putting into practice a sex position I still hadn’t learned at the academy.
At first she stayed in the cowgirl posture and rolled her pelvis in slow, circular motions, gently stimulating every part of her walls. The way her clit ground against the base of my cock was dizzying. On top of that, every single fold inside her pussy dragged along my length—it felt incredible.
“Haa, haa… Sihyuk, it’s amazing… that feeling of being completely filled up, nngh!”
Even while panting she never stopped working her hips. Sitting on top of me and rolling her pelvis in circles naturally drew my gaze to her full breasts, so I reached up and squeezed them. Those soft tits squashed against my palms and bounced. The pliant, hot sensation set my excitement blazing. I clamped both hands around her waist and pulled her even tighter against my lower belly.
“Noona, you really… have a divine pussy.”
“Hehe, thanks for the compliment. Want me to squeeze tighter?”
She answered lightly, yet the steadily quickening pace of her hips showed she was nearing her limit. Before long the circular grinding turned into a vertical, slamming piston.
Slap, slap, slap.
Once she started bouncing, the sound of flesh meeting flesh filled the room. Beads of sweat dotted her forehead and moans she could no longer hold back spilled from her lips one after another.
“Hyaang! Ah, nn! Sihyuk, I—I’m gonna come…!”
“Already?”
“Your cock is… too big… nngh!”
Barely two minutes had passed, but I didn’t show any disappointment. Given how much more sensitive the women of this world were, even with her skill it seemed inevitable she would climax easily.
Her pussy convulsed violently and milked my cock. I marveled at the intense pleasure; if I hadn’t just come earlier I might have finished right then.
“Hyaaaaang!”
In the end Seol noona collapsed onto me with a short scream. Her body trembled finely and her cunt twitched as if trying to wring out every last drop of sensation.
After barely any hip-rolling at all, Seol noona had come first. She lifted her head while gasping for breath. Pleasure and apology were tangled together on her face.
“Sorry… the theory is perfect but this is my first time putting it into practice with you… your cock is just so big… I came right away.”
She apologized almost tearfully, as if she truly meant it. The sight was cute, and at the same time a fierce sense of conquest surged through me. She was short on experience and my cock was simply too large—what could she do about it? Even this lewd teacher was nothing more than a helpless female in front of my dick.
I grinned and gripped her waist hard.
“I’ll make you come.”
The instant the words left my mouth my hips snapped upward.
Thwack!
The cock that had been passively receiving her movements until now went wild like an unbroken stallion and stabbed into her deepest place.
“Hyaat?! W-wait…”
A scream-like cry burst from Seol noona’s lips. Her body, used to the cowgirl rhythm, was helplessly shaken by the unexpected deep, powerful thrusts rising from below. My glans parted her soft walls without hesitation and knocked against the entrance to her womb. I didn’t stop; I drove up again.
“Aaaahnn…!”
A far more urgent, desperate cry tore from her than before.
“How is it, noona? Getting fucked from below feels pretty good too, right?”
I grinned and pulled my hips down only to slam them up hard once more.
“Ah! Nn! Wait, Sihyuk, it’s too—too deep…!”
Her pretty face twisted with pleasure and panic. She clutched my shoulders trying to keep her balance, but the relentless cock spearing up from below only made her upper body bounce violently. Using my strong lower body I kept driving my hips upward without pause.
“Don’t like it? Should I stop?”
“No! No, that’s not it…! Hnngh!”
Her pussy was honest. Every time I thrust up, her walls writhed as if they had been waiting and stretched tight around my cock. They squeezed wantonly, as if begging me not to leave, as if begging me to go even deeper.
Collapsed against my chest she shook her head from side to side. Was she asking me to slow down? I had no intention of granting the request. Instead I gripped her waist even harder so she couldn’t escape my movements.
“You came first, noona. This is your punishment.”
Or was it a reward? I couldn’t remember.
“I’m sorry, I’m sorry…! Nn! I’m—I’m gonna come…! Again…!”
The moment my cock knocked against her cervix again, Seol noona hit her second climax. Her body went rigid for an instant, then began thrashing as if she had been electrocuted. A body that had already come once could not withstand the sudden surprise assault; it crumbled helplessly.
“Too fast, hiiik, hiiiit…!”
Her pleas dissolved into pleasure-soaked moans and never formed proper sentences. Every scrap of academy theory seemed forgotten; her body was pouring out nothing but pure instinctive reactions.
