23 – Sex Education (3)

Even as her cock was being licked and her head stroked, strangely enough, Hayoon didn’t feel bad.

Rather, she felt happy, as if she was being praised. It was something she could never have imagined in her normal state.

However, Hayoon smiled with tearful eyes and said,

“T, thank you…”

“But at this rate, you won’t be able to make a man cum all day.”

“Ah…”

Hayoon let out a regretful sound as the hand that had been stroking her so gently moved away coldly. Mr. Choi didn’t even glance at her, turning his head to ask,

“Baek Sora, what should you do in this case?”

“…You must intensively stimulate the man’s erogenous zones.”

“Explain in detail.”

“In detail, you mean.”

Baek Sora blinked at those words and looked at Hayoon, saying,

“First, since you can’t use your hands, you have to make him cum with only your tongue and mouth, so you need to stimulate the glans as strongly as possible. Generally, it’s better both visually and sensually to swallow the glans and suck it while stimulating it with your tongue.”

“Are there any other methods?”

“…There’s also the method of asking the man. You can grab his head and beg him to use your mouth like an onahole. It’s the easiest method since you only need to tighten your throat.”

“So, what does Trainee Hayoon think?”

“Y, yes? Th, that is…”

Hayoon’s mind raced as the arrow suddenly turned towards her. Even with her brain function impaired, she knew that if she didn’t answer properly, she could lose her senses like before, so she was desperate to find an answer.

Of course, she couldn’t think of anything even if she tried. Even when she was a man, she never cared about sex techniques. She always moved as her body desired, as her desires led her, and never did it while thinking about such things.

“Trainee Hayoon. Why aren’t you answering?”

“Ugh, ugh…”

Hayoon looked around tearfully at Mr. Choi’s urging question.

Ryujina, sitting in the front, sighed at the sight of her movements, like a chick looking for its mother.

‘That Mr. Ha, huh…’

She already knew from Hongryun that she had been doing it heavily with the instructors. But since she acted the same as usual, she thought that her nature wouldn’t change, but in the end, she seemed to have become just another fucktoy here.

“Ugh…”

The vibration in her lower abdomen, which she hadn’t paid much attention to, began to feel a little pleasurable. Ryujina blushed and quickly turned her gaze away. Regardless, Hayoon looked around urgently. But all she saw were gazes that were not friendly to her.

Kim Seonah was the only exception, but she was blushing and looking at her desk because of Baek Sora’s explicit descriptions, so she couldn’t make eye contact.

No, on closer inspection, she was climaxing. Hayoon couldn’t hold back any longer and climaxed as well, seeing her covering her mouth and trembling.

“Hngh…! Hng!”

“What are you doing, climaxing on your own, you bitch.”

However, Hayoon looked at Mr. Choi with terrified eyes as he grabbed her face and approached her menacingly.

“Trainee Hayoon. How much are you ignoring the instructor?”

“Mmph, mph…”

She wanted to argue that she wasn’t trying to ignore him, that she was thinking, but she couldn’t speak because of the large hand that was tightly gripping her face, including her mouth. She licked his palm pitifully with her tongue, but Mr. Choi didn’t care and said,

“It seems Trainee Hayoon needs a little more training.”

With those words, the hand that had been holding her face fell away. Hayoon exhaled the breath she had been holding, but when she looked up again, she couldn’t see anything. At the same time, she couldn’t hear any more sounds either.

She had been fitted with the blindfold and earmuffs again. Hayoon tried to scream as the things that took away her senses began to be put on, one by one. But before she could, a gag was forced into her mouth, preventing her from doing even that.

In the end, it was back to square one. The vibration of the dildo, which had been bearable, felt more violent than ever. Her body, which had tasted a brief moment of peace, was now receiving the stimulation even more sensitively.

Again, she’s going to cum again. Hayoon sobbed and climaxed. Pleasure spread like ripples, pounding her entire body. Like weak aftershocks occurring sporadically after a major earthquake, shallow climaxes surged without ceasing.

She couldn’t breathe. Her heart ached painfully due to the frequent pleasure and increased excitement. It was a moment that would have ended the life of an ordinary person with a heart attack, but the body of the infected endured even that.

No matter how much pleasure is injected, the infected do not die easily. The number of infected who die from overstimulation is so small that they can be counted on one hand.

Even if they use the most powerful drugs. It was truly a cursed body. Hayoon cursed her body in the midst of the surging pleasure.

However, whether she thought so or not, the inorganic pleasure tool that penetrated her pussy vibrated tirelessly, stimulating Hayoon’s erogenous zones.

Someone, please save me. I’ll listen well. I won’t even throw away trash anymore. So please-

She utters desperate voices, but they don’t reach outside. They echoed meaninglessly only inside her body, repeating the same words. Only to escape this situation.

However, it wasn’t until after the afternoon’s work was finished and before the evening roll call began that Hayoon was released from that state.

“…This is too much, no matter what.”

Ryujina muttered as she looked at Hayoon, who was leaning weakly on the chair. She could still hear the whirring sound, but she wasn’t reacting at all, only twitching occasionally.

The reason why she was still receiving ‘training’ even after the afternoon’s work was finished was because of Mr. Choi’s orders. He had told them not to release her until the evening roll call, so they couldn’t do anything about it.

Or maybe they didn’t want to do anything about it. Ryujina turned her head and said to Kim Seonah, who had come with her,

“It’s almost time, let’s release her.”

“Ah, yes…”

Kim Seonah, who couldn’t take her eyes off the miserable sight, moved in a hurry at Ryujina’s words.

She cut off the cable ties that were fixing her hands and feet to the chair with the pliers she had borrowed in advance, and took off the blindfold and earmuffs that were covering her eyes and ears. Finally, when she took out the gag that had been in her mouth, Hayoon’s face was finally fully revealed.

It was a terrible sight. Her eyes, which were blankly open, showed no signs of life, and her face was a mess with the fluids that had flowed out. The gag that had been in her mouth for a long time was so strongly chewed that there were teeth marks on it.

In addition, the condition of her teeth wasn’t very good either.

Ryujina looked around in her mouth, found a tooth that seemed to be in the worst condition, and put her hand in and pulled it out.

“Ryu, Ryujina-ssi?!”

“It’s okay, it’s okay. It’ll grow back in a week.”

“G, grow back… What does that…”

“Not like a shark, right?”

How do you know that? Kim Seonah wanted to ask, but she couldn’t bring herself to ask after seeing Ryujina’s calm expression.

“Now, all that’s left is the dildo stuck in her below… Kim Seonah, lift Hayoon up a bit.”

“Yes…”

When she grabbed her underarms and lifted her up, she felt too light. After all, she had spewed out all the moisture in her body for several hours, so it was only natural that she was so light.

While Kim Seonah was thinking that, Ryujina grabbed the end of the dildo that was tightly blocking her below and pulled it out with all her might.

“Hiii?!”

“Ah, Hayoon-ssi!”

“Hold her tight!”

Ryujina shouted at Hayoon, who suddenly started to thrash.

Kim Seonah hugged Hayoon tightly and whispered in her ear.

“It’s okay. It’s over now.”

“Ah, haak…!”

But it didn’t reach her at all. The flesh that had been holding the dildo tightly was pulled out, injecting pain and pleasure.

Hayoon felt a sensation as if sparks were flying in her brain and trembled.

“How big of a thing did that guy put in there…!”

“Haaah!”

Ryujina pulled out the dildo, which was almost completely out, with all her might. At the same time, Hayoon reached climax. Ryujina, who was hit directly by the gushing fluids, muttered in disbelief as she looked at the size of the dildo she had pulled out.

“What kind of black cock did he stick in there.”

It looked to be roughly 30cm long, and the diameter of the glans alone looked bigger than her palm. No wonder it was so hard to pull out. Ryujina sighed as she looked at Hayoon, who was arching her back and repeating climaxes.

Her pussy, which had been tightly closed because it had been swallowing a large dildo for a long time, was gaping.

Well, that’ll come back soon too. Ryujina thought so and picked up the dildo and got up. It was her job to wash it and put it back in its place. She said to Kim Seonah, who was holding Hayoon tightly, who was thrashing in climax,

“Let’s go to the shower room. Let’s clean up… after roll call.”

“Yes…”

The smell of female pheromones was so strong in the classroom that it stung her nose. Not that it wasn’t always like that. Ryujina thought so and headed to the shower room with Kim Seonah, who was carrying Hayoon on her back.

Even as they did so, Hayoon, who was being carried on her back, twitched and repeated shallow climaxes with moans.

Kim Seonah looked at her and said worriedly.

“Will Hayoon-ssi be okay?”

“It’s okay. It’s because it hasn’t been long since the training ended. She’ll be fine after a while.”

It’s just that her body has been forced to digest the excessive pleasure for too long since the training ended. Maybe even the feeling of the wind blowing on her skin will feel like pleasure right now.

Of course, so will the stream of water washing away the fluids. When she turned the lever, a stream of moderately warm water poured out of the showerhead.

When she sprayed it on Hayoon, she started to squirm like a cockroach that had been hit with insecticide.

“Haa, hngh…!”

“A, are you sure she’s okay?”

“I told you she’s okay. Rather, doing this will help her recover faster.”

Ryujina squatted down, rested her chin on her hand, and sprayed water on Hayoon.

Looking at that scene reminded her of when she became infected in the military. At that time, there were more than 100 people in the unit, and she had to deal with them for almost a week without rest. That’s why she could empathize with her condition more than anyone else.

A contradictory situation where you can’t breathe, you feel like you’re going to die soon, and you feel good even though it hurts. It was an experience she never wanted to have again. That’s why she tried to adapt to the training center thoroughly.

She would have adapted faster if some crazy bastard hadn’t been punching and raping her whenever he was bored.

“Why don’t you start accepting it and adapt as a trainee?”

Ryujina muttered to Hayoon, who was twitching, as if complaining.

Of course, it was impossible to know if she had heard those words.
