The Difficult Walls of the Females (1)
"Yes, hello. I'm Yoon Suhyun, and I'll be taking on the role of team leader this time. It's just a title, though; Ha-yun will be handling the actual command."
"Nice to meet you. I'm Yoon Nahyun, and I'm participating as an assistant. Don't worry, I won't be entering the Gate."
"It's been a while, Suhyun. I'm Chief Im Yewon, and I'll be in charge of the administrative work related to this Gate. Yoon Nahyun, you'll be assisting me."
"I'm Yang Ha-yun. Since the others are meeting Suhyun for the first time, please introduce yourselves."
"I'm Yoo Ra-on, taking on the role of tanker."
"I'm Kim Seo-hee, in charge of combat support and transport. Well, I look forward to working with you all!"
"Combat support, Chae Ryu-ah."
? The others are all fine, but that woman named Chae Ryu-ah... Setting aside the fact that she's using casual speech, she looks way too young. She has a small frame that barely looks 150cm tall and wears her hair in a rare braided style.
'Those idiots at the Association... were they so desperate for manpower that they ended up like this?'
I signaled to Yang Ha-yun, who stepped closer, and I whispered quietly.
"Hey... Ha-yun, why is a kid who should be in school here..."
"Ah, that... well."
Perhaps guessing what we were talking about, Chae Ryu-ah blushed and spoke up.
"Hey! I'm twenty-two, too! Ha-yun unnie! You didn't say it was a man!"
"Now, Ryu-ah..."
'Twenty-two? Don't give me that bullshit.'
"Oh, seriously! We promised not to include men in the party... Men are all the same, look at him already glancing around!"
"Ryu-ah, stop. This person came a long way to help us, don't talk like that."
When Yang Ha-yun spoke firmly, Chae Ryu-ah grumbled but didn't escalate the situation further.
"Suhyun, I'm sorry... It's just that Ryu-ah... she doesn't really like men."
"Ah, I see."
I could tell from the way Chae Ryu-ah looked at me with her arms crossed. That look was different from Yoon Jihyun's. If Yoon Jihyun just had a prickly personality, Chae Ryu-ah had a look of pure, genuine distrust for the male gender itself.
"Well then, let's go in, finish the briefing, and get some good rest today."
"Haa... shall I head in now?"
The briefing ended early. Aside from Chae Ryu-ah constantly glaring at me, the rest of the team members were fine. The problem was that the Association only booked one room, so I had to share it with my sister. I tried to book another room with my own money, but there were no rooms left in the hotel, and my sister said it was fine, so we just decided to share.
I let my sister shower first and spent some time sitting in the hotel lobby.
'Huh? Chae Ryu-ah?'
Chae Ryu-ah was sitting in a lobby chair, talking on the phone.
"Ye, yeah."
"A new team member? Yeah, it's a man... men are all like that... she doesn't trust anyone but herself... yeah."
"Yeah, I'm telling you, he keeps looking at me weirdly... oh, and when I get back this time... as promised... yeah..."
Chae Ryu-ah smiled faintly and started twirling her hair with her finger.
"Huh? There are a lot of people here... ah, okay, I love you, I'm hanging up!"
I made eye contact with Chae Ryu-ah as she ended the call and stood up.
"W-what! Were you eavesdropping?"
"Why would I eavesdrop on your call..."
'Casual speech is her default setting, huh...'
"D-do you have something to say?"
"You were the one who spoke first... never mind."
I didn't want to waste my breath. 'Besides, a misandrist with a boyfriend... what is that?'
Leaving Chae Ryu-ah, who was glaring at me with dissatisfied eyes, I headed to the room.
Click-
The room lights were off, and my sister was sleeping under the covers.
'Of course, there's only one bed.'
I quietly grabbed my towel and toiletries so as not to wake her and entered the bathroom.
Whoosh-
'I hope this ends quickly. Should I save up some money and buy a car... it's a hassle to keep walking around with Mom...'
I was lost in the hot stream of water falling from above, eyes closed, when it happened.
Click-
?!
The person who opened the bathroom door and walked in was none other than Nahyun, my sister.
"Eh? Sister? Wait a minute..."
I hurriedly covered my private parts with my hands. My sister, who had been wearing a robe, smiled slyly and untied the knot, letting the robe fall.
Thud-
'What is this? What is this? What is this? Seriously...'
Her violent, voluptuous figure, which looked exactly like Mom's, was laid bare. My sister walked slowly toward me.
'Is she sleepwalking or something?'
"Sister, stop for a second... what are you doing right now..."
My sister stepped closer to me under the water.
Squish-
My sister's large breasts pressed against my chest.
'Ah, damn it... if I get an erection now, I'm screwed... focus.'
Unable to push her away, an uncomfortable standoff continued.
"Sister... say something, at least..."
My sister brought her mouth close to my ear and whispered.
"Suhyun-ah... did you think I... wouldn't know?"
"What?"
My heart sank.
"That you do that with Mom every night... did you think I wouldn't know?"
"..."
This voice wasn't an interrogation; it was a confirmation. There was no way out.
"I went to Mom's workplace yesterday for a final check, but Mom wasn't there? Where did you two go? Did I interrupt you? Huh? Answer me, you little brat."
"I... sister... that... I'll explain... I'll explain everything..."
My happy life is about to meet its end as soon as it began.
Inside the room, I am currently kneeling on the floor, not even having dried off. My sister is sitting on a chair, legs crossed, wearing her robe, looking down at me. I explained everything that had happened with Mom to her, beautifying it as much as possible. I emphasized that there was absolutely no coercion involved. It seems my sister had been eavesdropping on my sex life with Mom every night for at least a few weeks.
"Hmm~ I'll believe you."
The biggest problem is the fact that I had sex with Mom. I faced the worst-case scenario of being caught by my sister having incestuous sex with Mom. The only saving grace is that my sister's attitude is soft.
'If I play my cards right... I might be able to avoid getting kicked out.'
"Yeah... so the most important fact you need to know, sister, is that between Mom and me..."
My sister stood up from the chair while I was talking.
"Stand up."
"Huh?"
"I said take your hands off and stand up."
"Huh? Ah, okay, okay."
Unable to disobey my sister's command, I took my hands off and stood up.
"It's... huge? But why is it so soft?"
"That's... it hasn't gotten hard yet..."
"It gets even bigger than this?!"
Slide-
My sister threw off her robe.
"Get it up."
"Huh?"
But my cock remained limp, not moving an inch. It wasn't because my sister's body wasn't arousing; it was because the situation was so uncomfortable that my cock couldn't react at all.
"Is my body... not good enough?"
"No, it's the best... no, that's not it..."
'Ah, Yoon Suhyun, you idiot...'
"Hmm... does it need more stimulation?"
My sister knelt down right there and began to caress my cock.
"Since you do it with Mom a lot, doing it with hands... isn't that great, right?"
"Huh?"
Slurp-
My sister swallowed my glans with her glistening lips.
"Sss-."
Slurp, suck-
She slowly started moving her head.
'What is this situation...'
The inside of my sister's mouth was similar to Mom's, yet strangely different. She didn't make eye contact like Mom; she just closed her eyes and sucked slowly, as if savoring it.
Suck-
"Phew... that's strange... it got bigger, but why is it still soft?"
My cock remained in a semi-erect state. The reason was clear. My tension had vanished the moment my sister took my cock into her mouth. If anything, my cock had been harder when I first saw my sister's naked body in the bathroom, or when her breasts docked against
