“Baek Hayeon, why are you skipping the submissive posture and worship kiss?”
…Ah.
At noona’s criticism, Hayeon’s face flushed with shame. She looked like she really didn’t want to do it.
She bit her lip and glared at me, but eventually knelt at my feet as though she had no choice. Then she bent deeply at the waist until her forehead touched the floor. It was a perfect dogeza posture.
Hayeon slowly raised her head, and her face was a complete mess. Shame and anger were mixed together.

With trembling lips, she kissed my rigidly erect cock. Her expression made her intense disgust obvious.
Her lips trembled spasmodically whenever they touched my cock—the glans, shaft, and even balls.
‘This is pretty damn arousing in its own way.’
The sight of a woman who hated penises—and a beauty at that—kissing my cock while making her disgust abundantly clear was incredible.
I felt like I was about to develop some kind of twisted fetish. All the other women looked as though they were crazy about me, but Hayeon was different. That made it fresh and arousing.
At the same time, I felt a little sorry for her, suffering from the strange mental illness that made her believe she was a man.
After the kiss, Hayeon reluctantly began fellatio. And, to be honest, her skill was terrible.
It was only natural, since she hated even the sensation of touching a cock.
“Uugh….”
Her aversion was painfully obvious: her lips weren’t properly pursed, and her tongue had gone stiff.
On top of that, my cock was so large that she couldn’t properly swallow even half of it, let alone reach the base.
“Miss Baek Hayeon, you clearly haven’t properly practiced expanding the space inside your mouth.”
Noona pointed it out sharply.
“As you can all see, to satisfy a man with a large penis like Sihyeok, the deep-throat technique, which utilizes the throat, is essential.”
“But even if you haven’t learned deep throat yet, it’s difficult to give pleasure when you perform fellatio as passively as you are now.”
Hayeon ignored her and moved her mouth clumsily, as though she wanted to finish as quickly as possible. Watching her made me feel mischievous.
I deliberately stretched out my legs while sitting in the chair and slightly raised the tip of my shoe. Then I pressed it firmly against the crotch of Hayeon’s jeans, right over her pussy.
From behind, it was hard to see what I was doing.
“Hnng…?!”
Her body jolted at the sudden stimulation. She stopped the fellatio and looked at me in surprise, but I wore a composed expression, as though nothing had happened.
“You heard the teacher, right? Try again.”
Whether Hayeon noticed that I was pressing her pussy or not, Iseol noona backed me up as well.
“What’s wrong? Your concentration slipped. Try again.”
At Iseol noona’s cold words, Hayeon reluctantly put my cock back in her mouth. I started gently rubbing her most sensitive spot with the tip of my shoe once more.
Hayeon glared at me resentfully, but she had no choice and began fellatio again. I put more pressure into my toe and pressed her pussy harder.
“Haa, nngh…!”
As her pussy was stimulated, Hayeon’s fellatio sped up slightly. It was as though she were desperately struggling to avoid climaxing.
But it was already too late. Her pathetically inexperienced pussy reached its limit after only a few strokes.
-Pshh!
“Hyaaang…!”
With a short cry, her pussy gushed out like a fountain.
Her jeans and panties were soaked in an instant, and her juices dripped onto the classroom floor.
She seemed to have lost all the strength in her body, burying her face in my cock as she breathed heavily.
“Wow… It looks like Hayeon has developed her mouth-pussy.”
“She came from fellatio alone….”
“Oh my, she climaxed from fellatio alone. She has an unexpected talent.”
“I thought she was doing a half-assed job, but I guess it was because her mouth-pussy is sensitive.”
“Isn’t mouth-pussy development an elective next semester? She got ahead this fast?”
The female college students behind me marveled. I laughed to myself, relieved that they hadn’t noticed I had been pleasuring her with my foot.
Next was the vice class president, Cha Ayoung. Her outfit was neat and covered a lot of skin, but it was so form-fitting that it emphasized her perfect figure even more.
Just like Iseol noona, it seemed that, in this world, clothes that women with large breasts had no choice but to wear were in fashion.
Ayoung’s fellatio was nearly perfect. If I hadn’t already received it from Iseol noona, I would have been impressed. Eighty out of a hundred. Noona was a ninety-five.
“It was excellent overall, but the transitions between techniques still aren’t smooth. Once you get more accustomed to the penis, you’ll be perfect.”
After hearing my feedback, Ayoung gave a small nod without changing her expression and returned to her seat.
Next was Subin. Perhaps because she wanted to show off to me, she was wearing a slightly sexier tank top than usual, one that revealed her navel.
“I-I’ll start…!”
Perhaps she had worked hard on her jaw muscles, because Subin took more of my cock into her mouth than last time. But she still couldn’t swallow all the way to the base.
Even so, unlike Hayeon, her performance was full of devotion toward me. It was cute watching her move her tongue earnestly despite her clumsiness.
Fifty points. I gave her a strict score. She was much better than Hayeon, who had earned thirty.
“You’re still clumsy, but I liked seeing how hard you tried. You’ll improve quickly with practice.”
My feedback was brief. Honestly, she was lacking across the board, so all I could do was tell her to practice hard.
Next was Chaerin. Perhaps because she had practiced that morning, she wore a confident expression. Her tight pants showed off the lines of her firm buttocks and thighs.
“Taking yesterday’s feedback into account, I’ll make it perfect today.”
Chaerin knelt before me with a determined expression. Her movements were filled with confidence.
-Schlurp.
A warm, wet sensation enveloped my entire cock. She was definitely better than yesterday. Her pressure control was steadier, and she wasn’t using much unnecessary force.
“How is it? Pretty good, right?”
It was cute watching her mumble the question with my cock in her mouth. Instead of answering, I gently stroked her head.
As she had learned, Chaerin attempted spiral fellatio. Her tongue began at the glans and slowly traced a spiral down toward the base, then climbed back up toward the glans.
Her clumsy but earnest effort was so endearing that my hips twitched slightly without me realizing it.
She demonstrated all the techniques she had learned in order. Especially when she sucked on my glans with her lips, a strange sense of forbidden pleasure sent a thrill through my entire body.
“Good job. You’re much better than yesterday.”
When I praised Chaerin after the practice ended, her face brightened immediately.
Despite her diligent tongue work, Chaerin scored only around sixty-five points.
“The pressure is a little weak, and your tongue movements are still awkward.”
After praising her only to follow it with cold feedback, I made Chaerin bite her lip resentfully.
Next was Yeji. She had come dressed in a short skirt and white blouse—an outfit anyone could see was sexy.
“Please take good care of me, Class President!”
She greeted me coolly before beginning, but the moment she assumed the dogeza posture, her eyes turned serious.
“Schlurp, schlurp…!”
Yeji’s fellatio was full of power. The pressure inside her mouth was especially intense.
Her tongue was a little rough, but her overwhelming physical strength made up for her lack of technique.
She occasionally failed to control her strength and nearly hurt me, but that precariousness was stimulating in its own way. Seventy points.
“Once you get more used to controlling your strength, you’ll be much better.”
Yeji looked disappointed for a moment at my feedback, but soon gave a carefree laugh and returned to her seat.
Next was Yuna, the gyaru. An off-the-shoulder top, a choker necklace, and a black sheer blouse with a black bra visible through it—today’s fashion was perfectly hot.
The gyaru-style girl knelt before me with a confident smile.
“Class president, I’m gonna enjoy this~”
Her fellatio began with a cute wink and was a work of art. The sight of her looking up at me with a smile in her made-up eyes was insanely arousing.
I had noticed it when she gave me glans-only fellatio last time, too, but her tongue was incredibly soft. Her technique was similar to that of the vice class president, Cha Ayoung, but the texture of her tongue and her eye-smile that seemed to melt me were no joke.
“Slurp, schlurp, hehe. My tongue feels good, right? Should I keep licking just the glans? Or the shaft?”
Her slightly laid-back attitude made Yuna’s fellatio even more special.
Eighty-five points. It was good enough to receive every day.
When I told her it would be good if she became more accustomed to the penis, Yuna nodded and returned to her seat, telling me to look forward to her next fellatio.
Finally, the long-tongued Nari stepped forward.
She was tall and slender, but her breasts and buttocks stood out clearly. The mini dress she happened to be wearing today suited her extremely well.
Nari smiled at me, but her gaze—and even her expression—held a hint of arrogance. And, as far as I knew, she had every right to it.
She was the best female college student at fellatio in our class.
Everything was perfect, from her technique and pressure to her temperature control. I was especially impressed by the way she watched my expression and adjusted her tongue, lips, and pressure in real time.
She didn’t stop there, gently stroking the inside of my thigh with her free hand.
“Oh, ho….”
It was incredibly thrilling. The muscles around my cock contracted hard, making it even more sensitive.
