Chapter 128 – Underground Battle (11)
“Ugh…”
Gently wrapping what can be considered the most sensitive part of a man delivered strong stimulation and pleasure to Sumin.
“Hehe…❤”
While stimulating her glans, Yuna grabbed her own breasts and began to move them up and down.
“Ugh…!”
“How about stimulating the upper and lower parts of the dick at the same time? I’m not used to paizuri, so I’m a bit clumsy. I don’t know if it’ll be okay.”
From Yuna’s perspective, it was said to be a more clumsy action than other actions, but just that clumsy action was enough to stimulate Sumin to the point of bursting forth.
“Ah… Sister…”
Yuna, seeing Sumin calling her, briefly removed her mouth from her glans and opened her mouth.
“Just stay still. As I said before, I acted carelessly and that’s why I got this erect. I need to make you ejaculate.”
After Yuna said that, she put Sumin’s cock in her mouth again.
“Um… Churp…”
Yuna continued to move her head up and down with Sumin’s cock deep inside her mouth.
“Umm…❤ Wow…❤ Churp…❤”
“Who. Sister?”
When Yuna saw Sumin calling her again, instead of answering, she bit all the way to the base of her pole and started sucking it.
“Wow…❤”
Yuna continued to use her mouth to taste every inch of his cock. As she continued to use her mouth to stimulate her own dick, her pleasure began to well up to the tip of her head.
“Ah… Sister!”
Sumin’s body flinched, and she sprayed a lot of white liquid into Yuna’s mouth.
“Wow…”
The semen that couldn’t all be contained in her mouth flowed down between Yuna’s breasts.
“Haa… Haa…”
Yuna eagerly tasted Sumin’s semen, which was sprinkled generously in her mouth, rolling it around with her tongue.
‘It seems like the flavor is a little less intense than before… But it still tastes good in its own way❤’
Yuna, who tasted her semen, thought so and swallowed the semen in her mouth.
“Gulp❤ Puha… How do you feel? Do you feel like you’ve calmed down a bit?”
“Uhm… Yes.”
After saying that, Sumin collapsed and lay down, probably from exhaustion. Sumin, who had been holding her head upright, suddenly lost strength and lowered her head.
‘I’ll let it rest for a bit and try talking to you again.’
Thinking like that, Yuna let Sumin sleep and recover her stamina.
————————————————– ——————–
“Oh…”
“Did you wake up? You must have been tired, so you passed out.”
“Yes… I’m sorry.”
“There’s nothing to be sorry about. It’s one of the physiological phenomena. Then, shall we look for the key again? It doesn’t look like it’s in your mouth…”
“Hmm… I guess so. I looked for it so hard, but it wasn’t there.”
“Then, shall we look somewhere else?”
“Um… Where should I look?”
“Earlier, when you were calming down, I checked the base of your cock, and it didn’t seem to be there.”
“Hmm… I guess it’s not here.”
“Yes. I did… Ah!”
Yuna, who was answering with a gloomy expression, screamed as if something occurred to her.
“Is it possible that the key to exit the room is not a physical key?”
“I’m not sure. The only information I heard about this room was from my sister…”
“Hmm… Now that I think about it, I guess so.”
“Now that I think about it, I also thought of one thing.”
“Have you come up with any good ideas?”
Yuna was looking at Sumin with eyes full of expectation.
“Something just occurred to me. It’s not something I would call a good idea, but I’ve recently heard of a room like this where you can’t get out with the door closed.”
“Hmm… I guess this isn’t the only room like this. So how did he escape?”
“It’s different for each person, but I heard that everyone escaped by satisfying certain conditions.”
“What were the conditions?”
“Everyone who entered the room was different, but…”
Sumin was hesitant about what to say, as if he was reluctant about something.
“What are the conditions that were commonly applied to those people?”
“Well… It’s all different, but I heard that everyone was able to leave the room only after doing something lewd.”
“Hmm… If that’s the case, I can understand why you were reluctant to talk about it. I guess I asked for no reason. I’m sorry.”
After hearing Sumin’s words, Yuna nodded her head and appeared to comply.
“Oh, no. I guess I was too sensitive for you to feel so sorry.”
The atmosphere in the room suddenly became cold, and there was silence.
‘If it was definitely made by Arin, she may have made it so that you have to do those things to escape the room.’
Yuna was thinking about how to get out.
“Ah!”
While Yuna was thinking about her thoughts, Sumin suddenly made an expression that seemed to remind her of something.
“What’s wrong? Did you come up with any good ideas?”
“Now that I think about it, when I was looking through the things in the room earlier, I found something that looked like a mechanical device?”
“Hmm… A mechanical device?”
“Yes. I didn’t know where I was going to use it earlier, so I just left it in its place without thinking about it. Now that I think about it, I thought it might be a clue.”
“What did that look like?”
“It looked like a digital clock with numbers written on the screen.”
“Hmm… I might find a clue there, so it wouldn’t be a bad idea to check it out first.”
Sumin came back from the corner with a stopwatch-like machine.
“It’s here.”
Sumin handed Yuna her machine.
“Thank you.”
On the screen of the machine Yuna received, the number 5 was written.
“Hmm… There’s a number 5 written on the screen.”
“Uh… 5?”
“Yes. It says 5. What’s wrong?”
“Uh… When I saw it, it looked like the number 10 was written on it.”
“So… Unless you remembered incorrectly, I don’t know why, but the number written down decreased because of what we did?”
“I think that’s probably true.”
Yuna looked excited as she thought she had found a clue to get out of this room.
“Yes, it would be nice if we could now find the reason why the number has decreased.”
“Hmm… First, it was said that you can only leave after doing something lewd. Should I try doing something lewd first?”
“Yes, I definitely think so.”
Even though she was sitting naked, Sumin still hesitated a little.
“Hmm…”
‘No matter how much you’ve done, it still seems shameful to take the first step. As the adult here, I have to guide him first.’
Thinking like that, Yuna carefully walked to Sumin’s side and placed her hand on his knee.
“Sister…”
Yuna laid Sumin down on her lap.
“Don’t feel too pressured, let’s just experiment with as many things as we can. Got it?”
Sumin said nothing, looking at Yuna and nodding her head.
“First… I’d better do this first while I’m on her lap.”
Yuna just opened her mouth.
“Buh…”
Saliva flowed out of Yuna’s mouth, fell on her hand, and formed a puddle on her. Yuna gently covered Sumin’s object with her hand and wetted it.
“There won’t be any inconvenience at this level, right? Then, I’ll get started soon.”
After saying that, Yuna began to gently caress Sumin’s belongings as she lay down with her right hand.
“Ugh…”
She felt her hands gently caressing her own dick, and a moan escaped her lips. The elaborate stimulation using her hands was delivering a different feeling of pleasure to Sumin than her previous stimulation.
“How are you feeling? Do you feel good?”
“Ah… I think it feels a little different from when I used her breasts earlier…”
“Um… Really?”
Yuna seemed to have taken Sumin’s words to mean that she was less aroused, and began to use both of her hands to stroke her goddaughter.
“Oh…?”
Sumin’s body was shaking at the way Yuna was caressing the sensitive part of her lower part and stimulating her upper part at the same time.
‘Ugh… Two places at the same time…?’
Looking at Sumin’s reaction, Yuna was smiling.
“Hehe… ❤ Looking at the reaction, this seems to be a bit of a good feeling. I guess it was right to change my method.”
“That’s not it…”
“Huh…? Please speak a little louder. I can’t hear you clearly?”
Sumin wanted to answer that she didn’t mean it that way, but Sumin, who was filled with pleasure, was unable to give a proper answer to Yuna’s story.
“Let’s just wrap it up like this❤”
Yuna said that and started moving her hands a little faster.
“Oh…”
Sumin felt like her own blood was rushing to one part of her body.
“Swoosh❤”
When Sumin was lightly scratched on the bottom, he couldn’t hold back and ended up ejaculating. Her sticky white liquid completely covered Yuna’s hands.
“Hehe… I’m done cumming❤”
“Haa… Haa…”
At the same time that Sumin, still with the lingering effects of ejaculation, was breathing heavily, a sound like a beep was heard from the machine from before.
“Beep!”
“Huh?”
Yuna turned her head to where she heard the sound and looked at her device.
“The numbers have decreased!”
When Yuna checked where the notification sound came from, she was able to see that the number displayed as 5 had been reduced to 4.
