Succubus System 323

Chapter 323 – Help Me to Relieve My Brother’s Lust? (4)

“If you’re done crying, quickly wash your face and wipe your eyes properly.”

“..Okay.”

When she entered the bathroom with her clothes on, she shouted at Yoo Seo-yeon in a voice that she was annoying, but she couldn’t even organize her mind and stood in front of the sink.

‘Still, my sister is crying.. It’s my fault..’

I don’t know if it’s a childhood that I don’t even remember. After her hair grew a bit, she never acted like a kind sister to Yoo Seo-yeon.

Regardless of whether or not her parents are around, she argues with each other and pours out harsh words. She kept ignoring Yoo Seo-yeon as if she was just a nuisance, but she never thought of it favorably.

Besides, she even touched her boyfriend this time, so she couldn’t look pretty.

It was something she would be grateful to have done with her treatment to this extent.

After she washed her face with that thought, she saw that her face in her mirror was much better than before.

‘All the makeup has been removed, but…’

She doesn’t usually wear heavy makeup, and when she did it with Choi Min-seok, she didn’t have the time to manage her makeup, so she came out with only really basic makeup, so it seemed okay to the point that even after it was removed, I didn’t notice much of a difference.

She was staring blankly into her mirror and sorting out her thoughts, but she came to her senses startled by the sudden voice of Yoo Seo-yeon.

“First of all, since I got permission from Minseok-ssi, I just need my permission to meet from now on. If I get caught meeting secretly, I don’t know what I’ll do either, so take care of yourself.”

“..Okay.”

No matter how much she thought about it, she answered with a gulp at the cool voice that didn’t sound like a mere scare.

“And before that. Let’s check if it will really help.”

“Check..?”

Unable to understand what she was checking, she asked cautiously, and Yoo Seo-yeon’s gaze flew straight into Yoo Hye-yeon’s pupils.

“I have to see if you can help satisfy Minseok’s cravings. Even if I don’t want much, even if I can’t, I have to endure for two hours. If I can’t do that, it doesn’t satisfy my cravings, but rather makes me frustrated. It’s better not to do it.”

“Two, two hours…?”

“Why can’t you?”

“…”

Can not do it.

Even if you add up the time from entering the motel, washing up together, and going all the way to the end, it’s barely over an hour. No matter how you think about it, two hours was too much.

“..Only time to have sex directly?”

“Of course.”

She asked just in case, but the answer she was expecting came back.

“You look like a real nail. Is an hour possible?”

“…”

“Ha..”

I don’t know how I can hold on to this, but if I think about the level of sex I’ve been through today, the time might be shorter than I thought.

Yoo Seo-yeon let out a sigh as if she was dumbfounded at the silence that lowered her gaze, unable to even show her bravado.

“Me, unlike my sister, I don’t have any experience. I’ve only done it six times now…”

Thinking that if it wasn’t this time, she might not have a chance to contact Yeongyeong Choi Minseok in the future, she spat out an excuse she came up with desperately.

“Hmm..”

“That, and.”

“And?”

She didn’t even think about whether her excuse worked, or the reaction of Yu Seo-yeon, who seemed to be slightly worried, and added her words right away.

“So… I’m also exercising because I can’t stand it too much, so I’m exercising to improve my stamina. I’m also exercising every evening.”

“Exercise? How do you do it?”

“Just.. Stretching, squats and abs, and.. Running for an hour..”

“Are you doing it every day?”

“That’s… Except for the day I meet my brother..”

On the day I met Choi Min-seok, the time was ambiguous, and it was difficult to walk after the relationship ended, so it was impossible to exercise. The next day, though, it’s strangely normal.

“Hmm..”

I’m thinking about it.

I tried my best to see if there was anything more appealing, but I couldn’t think of anything other than exercise.

“No matter how hard it is, it’s too short to last an hour…”

“Ah, it’s not too long ago. As long as I gain some stamina, I can hold on. I haven’t done any exercise before.”

Even though I’m not tall, I’ve never exercised except what I was told to do at school because I don’t gain weight enough that I don’t need a diet.

I took care of her breasts in my own way so that they wouldn’t sag, but it wasn’t an exercise that would increase my stamina like running, so I could leave it out.

“Exercise. Can you keep doing it in the future?”

“Everything, of course.”

In the first place, the goal she set while working out was to build the stamina to last for two hours like Yoo Seo-yeon.

It was about two hours since Yoo Seo-yeon and Choi Min-seok were entangled in her own house. It was a goal she set with the mind that at least she did not want to lose.

“Okay. Then let’s watch the stamina side.”

“What else…?”

She was relieved thinking that she had barely been allowed to. Yoo Seo-yeon said that there was still something left.

“I’ll just see how you do it yourself. No matter how long you hold on, you won’t be completely satisfied if the compatibility doesn’t match. We’ll have to see if Min-seok is satisfied even when he’s sober.”

“Isn’t that a disadvantage if you can’t do that for a long time..?”

“I’m saying this because stamina and compatibility are different issues. You can tell if Min-seok is satisfied or not, so you just have to do what you’re doing.”

I don’t know. Naturally, the thought came to her, and she became jealous, but she suppressed the rising feelings because she was not in a situation where she could accept that emotion straight away.

“Then… Do it in front of unnie’s eyes…?”

“Of course. How do you make a decision without seeing it?”

“That..”

“Don’t do it if you don’t like it.”

“…I’ll do it.”

In the end, the person I regret was not Yoo Seo-yeon, but myself, so I can’t refuse no matter how much I feel rejected.

In front of Yoo Seo-yeon.

As soon as I saw her for the first time, she was so engrossed in me that I could be sure that it was love, even though I hadn’t experienced her heart pounding so much that I thought my heart would stop.

When she was humiliated by Yoo Seo-yeon, she did, but she didn’t want to give up.

“Okay. Let’s go then.”

“..Huh.”

In the end, I followed Yoo Seo-yeon’s words and came out of the bathroom hesitantly.

Her heart sank once more at the sight of Choi Min-seok avoiding his gaze as if he was uncomfortable after passing by, but it was something she had to endure because she had committed a sin.

“Mr. Minseok.”

“Huh.”

“Once the agreement is over, let’s try it with Hyeyeon now.”

“Now..?”

“I think it would be better to do it right now. If I put it off for no reason, I think I will keep thinking about it and get stressed out. It’s okay, right?”

“..I really shouldn’t drink alcohol.”

Choi Min-seok, like himself, also expressed discomfort when he said that he was doing it right now, but at a few words from Yoo Seo-yeon, he sighed and agreed.

He was the one who did the wrong thing, but seeing Min-seok Choi unable to show his arrogance only increased his guilt.

“What are you doing? Neither take off.”

“Hyeyeon is…”

“I’ve told you everything, so don’t worry.”

“..Okay.”

Choi Min-seok took care of himself even in this situation, then sighed deeply and began to take off his clothes.

You may have gotten used to it by now. Whenever my eyes go to places like broad shoulders, smooth and toned muscles, or hollow collarbones, my face heats up for no reason.

Still, I couldn’t let Choi Min-seok take off his clothes, so he took off his clothes in the same way, enduring the feeling of shame.

“Mr. Min-seok… Sit down again.”

“Okay.”

The two became completely naked, and Yoo Seo-yeon, the only one wearing clothes, took the lead in the situation.

“And Hyeyeon, you… Do you know how to do fella?”

“I know, I know…”

“Then give it a try.”

It seems that the reason Choi Min-seok was sitting on a chair instead of a bed was to check his fella skills first.

“Ha..”

How did things turn out like this?

Until Choi Min-seok received Yoo Seo-yeon’s phone call, he was really happy as if he had the whole world, although he wasn’t without complaints or insecurities.

It was hard to believe that now she had to suck her sister’s boyfriend’s cock in front of her sister’s eyes.

Even so, he didn’t want to refuse and give up, so he awkwardly knelt down in front of the chair Choi Min-seok was sitting on and slowly poked his head in front of his cock.

‘..Not standing.’

Normally, there was no time to watch the non-standing figure, and there was no time to properly see the sinking figure.

The cock in front of him now was in a state where his head was lowered as if he had lost his strength, unlike his usual bulging and rigid appearance.

Of course, even in such a state, it was so big and thick that it couldn’t be compared to the normal level, but anyway, it felt strange to see it without energy.

‘..Shouldn’t it be built first?’

With that thought, she carefully gripped the shaft of her unerect cock and lifted it up, opening her mouth and sticking her head forward.

“Aww.”

Not having an erection yet, it was comfortable not having to open her mouth wider than usual to swallow her.

“Um.. Churub.. Chuub.. Chug..”

With the cock in her mouth, carefully roll her tongue to stimulate the glans.

What if I don’t write? To the point where such concerns were overshadowed, the cock reacted quickly and trembled, then rose so big and hard that it filled her mouth in an instant.

“Whoop, whoop, whoop…”

At first, I was taken aback when I saw that it was jumping and growing in her mouth and standing tall. But now I was able to pull my head back skillfully to accept the erect cock.

“Don’t pay attention and keep going.”

Maybe this was good enough? Thinking of doing it, I glanced around and looked at Yoo Seo-yeon’s expression, but it didn’t seem like she was doing well at this level.

“Huum.. Tzung.. Chulub.. Chew..”

If it’s a fella, I’m confident that I’ve improved in my own way while practicing with the dildo I ordered myself.

As he swallowed his cock little by little deeply, he closed his mouth, slowly rolled his tongue and sucked on his cock while sliding his head back and forth, feeling the cock in his mouth sizzling pleasantly.

“I’m glad you know how to do Fella.”

Is this good enough? I couldn’t look at his expression because I was concentrating on the fella, but the voice I heard didn’t sound bad.

I wish it had ended there.

“Still, I still have to practice more.”

At the words he added a beat late, he felt annoyance rising up without even realizing it.
