Don't Underestimate the Sexual Appetite of a Woman in Her Thirties

I trembled in terror, my eyes wide as I stared at Na-yeon’s mother.
She tilted her head, looking at me with eyes clouded by lust, and began to knead our joined hands in an obscene manner, muttering under her breath.
"...Hehe, I’m just kidding, just kidding. Your reaction was so cute that I couldn't help but tease you. Of course, I trust you, Teacher Jihwan."
"U-uh... Ugh... Yes..."
"...But that doesn't mean it’s okay if her grades don't improve."
As Na-yeon’s mother suddenly stiffened her tone and raised her eyebrows sternly, I flinched and clamped my mouth shut.
She narrowed her eyes, leaned in close to me, and whispered coldly.
"If she doesn't get at least a 3rd grade in this upcoming exam, I’m going to change tutors immediately. This is an unavoidable measure for my daughter’s sake... you understand, right?"
"Ugh... Y-yes..."
I answered in a dejected voice, my face cast in deep shadow. Since the decision to continue tutoring was, naturally, the absolute authority of the parent, there was nothing I could do even if I felt wronged.
Of course, with Na-yeon’s current skills, avoiding a 9th grade would be a miracle, let alone reaching a 3rd. It might actually be better for her to just fill the OMR card in a straight line and take a nap rather than trying to solve the problems vaguely.
I let out a deep, heavy sigh, my face filled with anxiety at the thought that I would surely be fired once this exam was over.
However, Na-yeon’s mother looked at me with a sly, seductive smile, and then whispered again in a soft, gentle tone.
"...If you want to keep tutoring, there is exactly one way."
"...Yes? A-a way? What kind of..."
I asked back urgently, my eyes wide with the desperation of a drowning man clutching at a straw.
That reaction was, in effect, a confession that Na-yeon would absolutely never reach a 3rd grade on this exam, but I wasn't in a position to worry about such things.
Na-yeon’s mother looked down at me with satisfaction, then suddenly rose from her chair, walked behind me, and wrapped her arms around me, whispering into my ear.
Her voice was even more intimate and seductive than before, making my ears feel like they were melting just from hearing it.
"...It’s nothing much, you just have to grant me one small favor..."
"A-a favor...?"
"Yes, that is... I want Teacher Jihwan to cook dinner for us mother and daughter. Just like a caring husband..."
As Na-yeon’s mother paused and then grabbed my chin to lift it, I was forced to meet the eyes I had been trying so hard to avoid. I stared back, my face burning red, and stammered.
"R-really... is that all it takes..."
Then, Na-yeon’s mother, who looked exactly like a carbon copy of her daughter, smiled sweetly and said.
"Of course! Hehe..."
"Ugh..."
...And so, about thirty minutes later.
A bizarre scene unfolded where I was wearing an apron in Na-yeon’s kitchen, chopping vegetables on a cutting board.
What Na-yeon’s mother had intended to make for dinner today was soybean paste stew.
I was only used to eating the food my younger sister made, so I was extremely clumsy at cooking myself.
For my sake, Na-yeon’s mother hugged me tightly from behind, pressing her soft breasts against my back, and carefully overlapped her hands with mine to help me chop.
"...Now, when you cut the pumpkin, hold the knife like this... That’s right, that’s right...
Hehe, our teacher’s hands are as slender as a girl’s, so I’m scared you’ll get hurt just watching you..."
"Y-yes..."
I kept my head bowed, my ears burning red, and mumbled in response.
"...There, you’ve done this much, so you can do it yourself now, right? Try it on your own from here."
"Yes..."
My head spun as I was overwhelmed by the seductive, mature atmosphere of a woman who knew how to torture a man’s heart dozens of times better than her daughter.
Na-yeon’s mother watched me with a satisfied look, then suddenly lowered the hand she had been overlapping with mine and naturally slid it inside my apron.
Then, with the tips of her long fingers, she began to gently scratch and tickle the crotch of my pants where my penis was.
Of course, my penis had been firmly erect since earlier, standing tall as if it were about to burst through my pants.
Na-yeon’s mother felt around with her hand to gauge the length of my penis, then gave a very satisfied, sly smile and blushed slightly.
"...What are you doing? You should keep chopping the pumpkin... If you don't focus, you might get hurt, so be careful, okay?"
"Ugh... Aah... Y-yes..."
I gasped, my mouth agape, struggling to focus all my energy on the knife in my hand.
But as Na-yeon’s mother slid my pants down, grabbed my glans, and skillfully used her wrist to jerk me off with wet, rhythmic motions, I found it difficult to even stand still, let alone focus.
Na-yeon’s mother’s hand-job technique was definitely on a different level from the clumsy ones of the female students I tutored.
With one hand, she gripped my testicles, sending shivers through me as she squeezed, while the other hand raced from the root of my penis to the tip, piston-like—the sensation was truly teaching me what it meant to be 'milked' dry.
Finally, unable to continue chopping, I dropped the knife and leaned against the sink, gasping for air.
"Ugh... Ugh... N-no..."
"...Hmm...? Why did you stop chopping, Teacher...? Don't tell me you're giving up already?
My, my... Teacher Jihwan, men with no grit are bound to be pushed around by women, you know...? Especially since you look so dangerously cute, you have to be even more careful...
I can't have that. I’ll have to fix your bad habits today..."
With that, Na-yeon’s mother pushed her tongue into my ear canal, licking and teasing until it felt like she was touching my eardrum.
With her braless D-cup breasts pressed against my back, her wet tongue digging into my ear, and my penis being rubbed without a moment’s rest, I finally had no choice but to clench my teeth, eyes rolled back, and squeeze out my seed.
"Hk!! Aaaah...!! Ugh, ugh, ugh...!!"
"My, my... How healthy you are, hehe..."
Na-yeon’s mother whispered in a sweet, trilling voice, seemingly satisfied with the amount of semen I was spraying.
I groaned, trembling on my tiptoes as I ejaculated in spurts.
"Haa...! Haa, haa, ahh...!"
But Na-yeon’s mother, showing no intention of stopping even after I had finished, lowered her head, spat a glob of thick saliva onto my semen-covered penis with the vibe of a delinquent from her youth, and began pulling on my sensitive, post-ejaculation glans with even greater speed.
I felt as if I were being electrocuted, my tongue lolling out as my entire body shuddered and I groaned violently.
"Hiiik...! Hik, ugh, aaaah...!!"
Na-yeon’s mother looked up at my ruined face, wearing an expression that suggested she found me too cute to handle.
"Haa... Haa... As expected, teasing a pure ■-type with a big dick is the best... Your pained expression is so cute❤️"
"Ugh!! Hk!! Ughhh!!"
Finally, as I was forced into a shi-o-fu-ki, spraying a fountain of thin urine all over the sink and the ingredients I had been preparing, Na-yeon’s mother stopped her violent hand-job and gently squeezed the remaining semen out of my urethra.
"Ugh... Ugh... Ugh..."
Na-yeon’s mother wiped the semen off her hand onto her apron and held me in a soft, gentle embrace against her chest until I calmed down.
When I looked at the ingredients covered in my own semen with a look of despair, Na-yeon’s mother covered her mouth and laughed, waving her hand as if it were nothing.
"...Don't worry, Teacher. It can't be helped if a little semen soaked in; my daughter likes your semen just as much as I do, so she’ll eat it well."
"E-eh...!"
As I turned my head in shock, Na-yeon’s mother opened her eyes slyly and muttered in a low voice while looking down at me.
"...Hehe, why are you so surprised? Did you really think I wouldn't know what you’ve been doing with my daughter?
Well, you’re still young, so I suppose that’s possible. Maybe my daughter doesn't even know that I know?"
"W-what...? Wha...?"
As I stood frozen like ice, eyes wide with horror, Na-yeon’s mother stroked my hair gently as if I were cute, then whispered even more sweetly with eyes full of lust.
"So, don't underestimate the sexual appetite of a woman in her thirties...? On the very first day you visited, I noticed everything from the thick scent of semen vibrating in Na-yeon’s room.
Na-yeon was pretending like nothing happened, but when you leave so many obscene traces of a male on her clothes and hands, it’s impossible for a woman of childbearing age to ignore it, no matter how much she wants to... Hehe..."
I was deeply shocked, my mouth agape, trembling as I looked up at Na-yeon’s mother with a pale face.
Soon, Na-yeon’s mother returned to a gentle expression, covered her mouth, and laughed.
"...Oh my, I think I’ve scared you too much. That wasn't my intention, ho ho...
I’ll take care of the rest of the cooking, so why don't you sit down and have some tea before you go?"
"...N-no... I-I’m fine..."
"...Is that so? Hehe... That’s a shame. It’s almost time for Na-yeon to be home..."
With that, Na-yeon’s mother kindly saw me off to the front door.
As I tried to scramble out of Na-yeon’s house as if fleeing, she waved goodbye, then narrowed her eyes and said in a low voice.
"...Then, Teacher, I look forward to next time as well? Don't worry, I’ll keep giving you plenty of 'bonuses'... Hehe."
I lowered my gaze, nodded slightly with a flushed face, and ran as fast as I could all the way home.
