Teacher, Is This Your First Time?

‘Which part feels good.’

‘Alright.’

Woo Tae-seon observed meticulously. Like a child upset about not being able to find the reason for a withering plant, sometimes he was almost affectionate to a touching degree. To an abominable degree.

‘Now try only from behind.’

Above all, at some point, Woo Tae-seon no longer allowed me to touch myself in front.

He demanded that I ejaculate solely from stimulation from behind, but this one thing didn’t flow smoothly according to Woo Tae-seon’s wishes. It couldn’t, because I was absolutely unable to ejaculate without touching the front.

‘C-can’t we stop now?’

Of course, the longer it took, the more painful it was for me.

The act of repeatedly showing someone else how I inserted and moved my own fingers inside that place with my legs spread caused tremendous mental pain. Moreover, what was even more painful was my body being forced to ejaculate for a long time despite not feeling any heat at all.

‘…Ungh, really now, hnngh. No more, hh, ah, I can’t.’

‘If it’s not enough, put in more.’

No matter how hard I tried until the hole was swollen, I just couldn’t reach the point of ejaculation with the sensation of stimulating only the back. Of course, regardless of my state, Woo Tae-seon persistently insisted on his will.

It hurt. It just hurt so much.

Even when I begged to at least be allowed to masturbate together for the finale, Woo Tae-seon wouldn’t permit it. Instead, he suggested another method. One that didn’t include my will at all.

‘Hmm. Try poking to the right. No, a little more.’

Over several days, Woo Tae-seon moved me little by little. Toward the places where I responded, in the directions I liked. He took great care, moving me very slowly.

The acting entity was my hand, but it moved not by my will but only by Woo Tae-seon’s directions. The fingers I had to insert and their number varied each time. The direction of poking the end, the speed, and the strength also varied.

Without knowing where Woo Tae-seon was leading me, I followed him diligently or stupidly. A little more to the right. Following his voice, I stirred my fingers hard against the deep hole.

In the end, what triumphed was Woo Tae-seon’s persistence.

“Haahngh. Haauung……”

Ejaculate burst from the tip of my rigid dick. I slowly withdrew the three fingers that had become sticky from being soaked in gel. I don’t know how much I had stirred, but even the withdrawn fingers were numb, and the hole was swollen to the point of bursting.

In the end, I had succeeded in ejaculating by stimulating only the hole. No, it would be more accurate to say that Woo Tae-seon had succeeded.

“Now, huff, ungh, now it’s done, right.”

I breathed heavily, sprawled on the floor. The voice that should have naturally returned wasn’t there. With an ominous premonition, I turned my gaze to the sofa and met eyes with the unresponsive Woo Tae-seon.

Just by meeting Woo Tae-seon’s eyes, all my emotions were exposed, but when Woo Tae-seon kept his mouth shut, I couldn’t read even a single line of his thoughts. I didn’t know if he was satisfied or still lacking. I just couldn’t understand Woo Tae-seon.

The tears that had never burst until now finally erupted belatedly. I tried hard to hold them back, but they spilled out all at once. Even though I tried to endure with hiccupping sobs, now even heat rose to my face. I looked at him with what must have been severely reddened eyes. No, I glared at him with eyes full of resentment.

“Huh. N-now, *hic*, it’s over, isn’t it.”

“……”

“I said, *sob*, I liked it, *hiccup*, earlier.”

Maybe it had only just sunk in. That I had now taken a truly irreversible step. That now I could really ejaculate just from being stimulated from behind.

Woo Tae-seon, who approached without saying anything, closed my disheveled clothes. With tears streaming down, I looked up at him. Woo Tae-seon fastened each loosened button back with a faint smile.

But even if he closed my clothes, everything else remained the same—my body still radiating heat, my thoroughly wet eyes, my chaotic inner thoughts—all of me was still the same.

“Did it feel good?”

“Yes… I already said, *sob*, didn’t I? *Sniff*. I said it felt good!”

Penetration, while being the main cause of my suffering, also paradoxically reassured me, because Woo Tae-seon didn’t demand more than that.

There were no acts he demanded beyond that, nor places he called me to other than his own home. Only at Woo Tae-seon’s house, only me probing my own hole until I ejaculated. That was all I had to do.

At some point, an implicit promise had formed between Woo Tae-seon and me that we wouldn’t go beyond this.

I had to move as Woo Tae-seon instructed and show my reactions honestly. That’s all I had to do. Then no problems would arise. It was a matter just between Woo Tae-seon and me, that no one else knew about.

“Good, teacher.”

And so I continued to create an unpleasant secret with Woo Tae-seon.
