The sight of my female classmate secretly masturbating made my lower abdomen swell as though it were about to burst.
Along with my lust, I also felt a touch of ridicule. She was a pervert masturbating during class, yet she had rejected me during practical training? Did she really hate sucking a man's cock that much?
I was lost in thought for a moment.
If someone was watching me, what behavior should I be displaying right now?
Would it seem normal for a lust-driven man to simply walk past after seeing the female in heat before him?
No, of course not.
Then what should I do now?
What else? Fuck her.
Hayeon had reached orgasm and was panting heavily from nothing more than a little touch to her clitoris.
The trembling of her white nape, white hair, and slender shoulders stirred my lust and made me act.
I snatched up her pants and square-cut panties from the floor.
Only then, sensing my presence, Hayeon whipped around.
What met her eyes was me, grinning mischievously while holding her pants and underwear.
“What were you doing all alone in such an isolated place?”
In an instant, Hayeon's face turned as red as a ripe tomato. Though she covered her pussy with both hands, she shouted sharply as if she refused to be outdone.
“W-what?! Give them back right now?! You pervert?!”
“Who knows? Isn’t masturbating in a place like this more perverted?”
I deliberately waved her pants in front of her with an irritating expression.
When Hayeon reached to snatch them, I pretended to hand them over and lightly tossed them toward her body.
At that instant, she reflexively focused on the panties floating in the air, and my hand shot out, gently enveloping her breast.
That enormous breast was too large to fit in one hand and so soft that my fingers sank into it.
Up close, its size was even more overwhelmingly imposing.
“Eek…!”
What burst out was too cute to be called a scream. I laughed, amused.
Even while laughing, the hand kneading her breast never stopped. After always dealing only with women who accepted things submissively, seeing her snap back like this turned me on intensely.
“L-let go of this?! I won’t let you off!”
Hayeon struggled, but her resistance felt less threatening than desperate and cute.
Ignoring her, I used the hand that had not been touching her breast to softly stroke her earlobe as if tickling it.
“Hngh…! W-what are you…!”
Contrary to her words of refusal, her aroused body twitched, hot fluid spilling between her legs. Just from touching her breasts a little.
To make her realize that fact herself, I lightly swept the back of my hand up her wet thigh.
“Eek…!”
Hayeon's face flushed even more when she realized that her body had reacted on its own.
She glared at me resentfully, but shame and pleasure mingled in her eyes.
She put all her strength into trying to shake off my hand kneading her breast, but an ordinary woman like Hayeon couldn't overcome a man's strength.
She was so sensitive that merely kneading her breast made the strength leave her legs, and she staggered precariously.
“You say you’re a man, right? Then why are you so sensitive?”
I struck at the sore spot: the fact that she went around calling herself a man.
At my words, Hayeon's shoulders flinched and stiffened. She glared at me resentfully, but her eyes were already hazy and drained of strength by pleasure.
“And there’s no man with breasts as pretty as yours.”
I deliberately rubbed her areola gently with my index finger.
“N-no, stop…!”
Hayeon bit her lips, trying to suppress her moan, but it was no use. Her body was already responding sensitively to each and every touch.
I lowered the hand that had been touching her ear and softly caressed the inside of her thigh, slick with fluid.
“Did you masturbate today? I hear women get sick with heat and hurt if they don’t relieve themselves regularly. Don’t tell me that’s why you were taking care of yourself here alone?”
“N-no! I’m a man, so I don’t have any of that, uh…!”
I placed my finger on her soft lower abdomen, just above her pussy, and rubbed in circles.
It wasn't direct stimulation, but Hayeon's body trembled little by little as if she were being caressed below.
More fluid flowed between her legs, enough by now that we could have sex.
“Is there somewhere you want me to touch? Tell me. Let’s say one ‘man’ is helping another ‘man’; I’ll give you special treatment.”
My teasing words twisted her face with shame. But the distance between us kept shrinking. I whispered near her ear.
“Where? Your breasts? Or maybe… here?”
I slowly lowered the hand rubbing her lower abdomen, finally bringing my finger to the entrance of her pussy, glistening with fluid.
“Hieek…!”
Hayeon's body sprang up violently as she reached orgasm.
“Hwaaaanng…!”
With a short, intense cry, another fountain burst from her pussy.
Hayeon collapsed into my arms as the strength left her entire body, panting heavily. Her first line of defense had fallen so easily.
“What are you going to do if you come already? We haven’t even started.”
“No more, I hate it… I’ll scream…!”
“Then scream.”
What good would screaming do?
I was only helping a female university student who had been masturbating. Besides, in this world, the idea of a man sexually harassing a woman was absurd.
Unless a woman was married to another man, touching her breasts a little wasn't a crime.
And above all, I had a reason for taking such a hard line.
“Haaah, there, hnnngh…!”
I gently swept my index finger once over her quivering clitoris.
Even as Hayeon said to stop and threatened to scream, she offered no real resistance. The strength had long since drained from her hands.
More importantly, her face already wore the expression of an aroused female.
As if she could tell me to stop when she was so horny and waiting for my fingers.
With her body heated, all she showed was a desire for more pleasure.
Hayeon's body had already flung open the door to pleasure and was far more sensitive than before.
Without stopping, I slowly explored the entrance of her wet pussy with my finger.
-Squelch, squelch.
Lewd sounds rang out.
The more my finger moved, the more abundant and viscous her juices flowed out.
I deliberately met Hayeon's eyes and smiled.
“Participate in practical training next time. It’d be a shame if you were the only one who didn’t. Right?”
“I w-won’t…! And get your hand out of my pussy right now, u-uhn, hngh, ngh…!”
“You really want me to take it out? But your body seems to be begging me for more.”
I stopped pinning her down by force and instead took a step back, showing the composure of someone giving her an escape route.
I kept only my index finger inside her pussy, moving it very slightly.

But that apparent leisure only left Hayeon unable to move. She seemed completely frozen between the thought that she had to run and a woman's instinct to be touched more.
Her thoroughly aroused pussy repeatedly clenched and relaxed on its own. Naturally, every clench sent an intense wave of pleasure through Hayeon.
Since Hayeon remained still, unable to choose, I had no choice but to choose for her.
-Squelch, squelch, squelch!
“Hwaaah, aaah…! Stop…! Wait, I said wait…! At least do it slowly, uuh!”
When I suddenly thrust into her pussy, Hayeon grabbed my hand. Of course, I didn't stop.
Pshht, pshht—the fluid she could no longer hold back burst out and soaked my fingers.
Looking down, I saw her clitoris standing prominently and her thighs glistening with fluid.
“You want me to stop? Really?”
I didn't touch the tiny clitoris directly.
Instead, I stopped thrusting into her pussy and teased the soft flesh around it, drawing circles.
When the pleasure abruptly stopped, Hayeon's body writhed impatiently. Without even knowing what she was doing, Hayeon leaned against me and let out lewd breaths.
“Haaah, hngh… really, stop….”
Before I knew it, Hayeon's lower body had thrust slightly toward me. As a result, my finger naturally touched her pussy.
“You do realize that while saying ‘stop,’ you’re rubbing your pussy against my finger right now?”
I grinned and pressed down on her clitoris with the tip of my index finger.
“What? W-wait, hwaaahhh…!”
With a scream incomparable to any before it, Hayeon's body shook violently again.
Apparently the pleasure was too much to bear; she shed a tear and sprayed a new fountain.
The stream shot wildly, splattering onto the floor and leaving a dark stain.
She leaned completely against me as if all the strength had left her body, panting heavily.
“Are you really a man? What kind of woman is this lewd and horny?”
“I’m a man…! I’m a man! Hngh!”
Hayeon's body kept trembling, causing her pussy to rub against my finger again. I didn't mind this either.
“You call that a man’s reaction?”
My fingertip touched her clit once more. Then, as if brushing dust off it, I mischievously flicked her clit—tap, tap, tap. Without stopping there, I lightly squeezed her breast.
“Guh, hngh…!”
This time, a sweet, sticky cry escaped, not even forming a proper moan.
She clutched my shoulder and trembled as if she'd been struck by an electric current. Hayeon didn't know what to do with the ecstasy consuming her entire body.
Perhaps because it was her first time having someone else touch her clitoris, this might have been the greatest pleasure she'd ever experienced.
Watching her, I smiled in satisfaction and brought my hand to my waist.
-Click.
The sound of a metal buckle coming undone instantly snapped Hayeon awake from the haze of pleasure.
“Eek!”
To be honest, I let my guard down a little.
I hadn't expected Hayeon, who had been leaning against my body like a female in heat until just now, to be capable of such explosive strength.
After a short scream, Hayeon abruptly turned, seized the pants on the ground, and despite staggering, desperately fled without looking back.
It looked less like a flight born of terror and more like someone flusteredly running away from a situation so embarrassing and humiliating.
I chuckled softly as I watched Hayeon's back while she fled in disarray. She was so cute that I didn't bother chasing her.
“Hey! Put your pants on before you run!”
I hadn't intended to force myself on someone who said she didn't want it. I only meant to make her give me a blowjob, but she seemed to have mistaken it for rape.
“Huh?”
Instead, I got my hands on something interesting.
At my feet lay the small white cotton square-cut panties Hayeon had failed to grab in her haste.
They still retained her body heat and scent, along with the full memory of her violent reaction moments earlier.
There were some traces of fluid on the underwear, but since they were square-cut rather than triangular panties, they weren't particularly arousing.
“I should return these.”
Grinning, I put the underwear carrying her scent into my pocket.
I looked back and forth between the drenched floor and my still-erect cock that showed no sign of subsiding.
To relieve this uncontrollable lust, I headed toward the infirmary.
