Chapter 136 – A Night Longer Than Expected (7)

“I won’t run away”

My sister couldn’t resist my urging and had no choice but to answer. Still, it seemed like he didn’t hate me as he answered me like he was whispering.

“Then fill this with your sister and bark like a puppy.”

I grabbed the string and put the end in my sister’s hand. She handed over authority to her older sister so that she could fill it herself.

“Ah, you don’t have to stand at attention now~ hehe. It’s cute.”

The older sister looked cute as she maintained her posture as instructed earlier.

“Ah…”

Still, I patted my sister’s head as if I was proud that she remembered my words and kept to her until the end.

My sister smiled happily at my touch and opened her mouth.

“This feels good… I feel like a real puppy…”

“When I become a puppy, I will do a lot for you.”

“Really? Why don’t you do it when you’re a human…”

My older sister whispers to me in an angry tone.

“You do it when it’s a human, but when it becomes a puppy, you praise it even more.”

“Umm~”

My sister nodded her head as if she understood a little? Then he grabs the end of her leash and leads it around her own neck.

Click-

“Good job, Kwak Soo-jeong.”

My older sister smiled again at my compliment, even though she called her younger sister by her own name.

“Woof… Woof! Woof…?”

My older sister barking like a puppy in front of the mirror wearing only panties. It was my first time, but she behaved pretty well for an older sister.

“Now I guess I’ll have to crawl on all fours, right?”

“Yes…”

“You have to answer with a dog. It’s a dog. Who is your current sister?”

“Ahh… Yes, no. Wow, wow…”

When I spoke in a low voice, my sister was slightly surprised and immediately made a dog sound.

“Right”

I stroked my sister’s head.

“Our Sujeong needs to start with ‘sit’ training.”

My sister was staring at me blankly, not understanding what I meant.

“Sit down!”

Shout out to your sister, ‘Sit,’ which is one of the commands given to dogs.

My sister thought for a moment and then got down on her knees with her hips touching the floor and her hands on the floor.

“That’s right. That’s how you do it. Isn’t it easy?”

Zeke- Zeke- Zeke-

The older sister who completes ‘Sit’ is rewarded with a pat on the head. My sister sat quietly and felt my touch.

“There’s still one more thing left to do to become a perfect puppy…”

I picked up a dog tail anal plug from a drawer containing adult toys.

“Eh, eeh…?”

For a moment, my sister’s eyes widened. She must have noticed that it had to be inserted into the anus.

“It’s okay, you just need to pinch it a little bit. It doesn’t take a lot.”

I took out the body lotion from the desk.

Continue-

Then, I squeezed the body lotion onto the tail plug and applied it.

“Did you say these panties are your sister’s favorite?”

His sister nodded, keeping her mouth shut to avoid human speech. However, my sister’s gaze was still focused on her plug and she had a fearful expression.

“It’s a shame. But it’s more important that my sister remembers what happened today.”

I held the plug covered in body lotion, took the scissors, and walked back towards my sister.

My sister’s eyes followed the sparkling scissor blades in a fairly dark room.

“Get up again”

“Bung…”

It was a pretty artificial dog sound, but I didn’t mind because I understood what was being said. That was enough for us to communicate.

“Should I raise my butt more?”

I came behind my sister and gently stroked her buttocks with my hands.

Then, like a magic spell, my sister’s buttocks rose to the height I wanted.

Zeke- Zeke-

And then I gently stroked my sister’s buttocks. The elasticity of my sister’s warm, lean, round buttocks and the soft material of her panties gave my hand a pleasant feeling.

“The panties feel perfect. You can say they’re my sister’s favorite. But…”

As soon as I said that, I grabbed the fabric near my sister’s anus with my hand and cut it with scissors.

Seokkeok-

The soft and tight fabric of my older sister’s panties began to be torn away with a terrifying slicing sound.

“Woo… Woo… Ugh…”

My sister had no choice but to suffer what I did.

Ssukkeuk- Ssukkeuk- Ssagak- Ssagak-

I couldn’t believe how many times I heard the sound of the fabric being cut in the quiet room, and soon it turned into panties that slightly exposed my sister’s buttocks. Only her buttocks were cut into square shapes.

“I deliberately tried to plug in without taking off my sister’s panties. It makes me feel better when I see my sister in her panties.”

I liked how my sister’s favorite panties were cut off for an insignificant reason and turned into pieces of cloth without any resistance. On the other hand, my older sister was in tears because of regret.

“···Huh…”

My older sister squeezed her buttocks, closing her eyes tightly as if she expected the plug to enter her anus right away.

“It’s okay, this is the smallest one.”

Zeke- Zeke-

I stroked my sister’s round butt again.

It would be nice to have an enema, but since it doesn’t take that much, I thought it would be okay to do without it.

“Shall we, Sujeong, open it ourselves?”

Tak-tak-

I lightly tapped my sister’s pretty buttocks with my hands. I felt her firm buttocks wrapped around my hands.

“Ah… Uh…”

But as a sister, she couldn’t disobey my orders. It seemed like a suggestion, but it was clearly a coercive order.

Chubuuk- Jeu-eok-

Love juice was already flowing into my sister’s buttocks.

The juice that flowed between her buttocks made an obscene sound and soon her older sister’s lovely pink anus was revealed.

I placed the plug in the anus between my sister’s wide open buttocks.

“It’s okay. It won’t hurt.”

Flinch- flinch-

Her sister’s face was filled with fear as she looked behind her, but she was holding on just fine.

Rather, it felt like my sister was letting me know that she was feeling her plug well.

Soouk-

The round, drop-shaped part at the tip disappears into my sister’s anus.

“H… Huh… Huh?!”

It was natural that there was a strange feeling in her anus, but her sister’s strange sounds clearly conveyed that feeling.

“It’s all in. You can stop spreading it now.”

When my sister removed her hand from her ass, she had a rather nice tail.

“The tail is pretty”

“Wow…”

My sister answers in awkward dog language. Her tail sticking out through her torn panties, the leash, and her sister’s posture combined to instantly turn her into a puppy.

“While my sister was relaxing, I kept her panties on for fear that the rotor would fall off due to her juices. Please don’t think I’m being to pervert.”

“···”

My sister, who could only use simple words like ‘bruise’, became increasingly frustrated.

“You can speak now. Human speech.”

“It was my favorite pair of panties.”

My sister kept fiddling with the torn part of her panties as if it felt strange.

“I’ll buy you something prettier next time”

“Tearing apart something I care about… But I’m still secretly excited…”

It was an unexpected answer. My older sister, who had opened her anus and was writhing in shame, was looking up at me while touching her torn panties.

“Really? Sister, you like this kind of thing again.”

My sister was able to accept many things within the limits allowed, so I was able to progress in my play little by little. I even felt excited to see that people liked the way I wanted to play.

“It’s not that I like it, but I’m excited because I’m being forced to do it. I guess it’s because my master keeps instilling it in me.”

“Being treated carelessly?”

I asked, recalling my sister’s reaction when I asked her to give her entire salary.

“Yeah… I think those things excite me.”

“What did you plan to spend your salary on?”

Suddenly, I became curious about what my sister would spend her part-time salary on.

“When I get paid, I have to buy clothes, eat delicious food, and buy Su-ah and my mom a meal once in a while. I just wanted to earn my pocket money.”

“Hmm… She’s a really dutiful daughter.”

“But the owner took it all away.”

My sister was openly advertising that she had pouted with her mouth out.

“Rather than buying food or clothes, I think it would be better to buy my sister’s teaching supplies. This money is mine anyway, right?”

At first, I was thinking of giving the money back to my sister, but I changed my direction a little. Making my sister’s hard work go in vain by spending money that should have been spent on good things on bad things.

I felt like there was nothing better than this to clearly recognize my position as a slave.

“Training assistant supplies…?”

“Yes, and instead of clothes, let’s buy obscene cosplay, dance with those clothes, and use them for things like that.”

My sister’s face turned red when she heard that I was dancing with an obscene cosplay. She turned so bright red that she could clearly be seen even in the dark.

“Well, about something like that…”

“It’s okay. I’m buying it with the money I confiscated from my sister.”

Flinch-

My sister seemed surprised when she told me about her money.

“The money earned through my sister’s labor is being forced to be used to satisfy the master. Isn’t that a bitch?”

I asked, stroking my sister’s head.

“···Good”

The answer came a little late, but looking at her sister’s condition, it didn’t seem like she was doing it because she didn’t like it.

My sister’s expression was looking up at me lewdly, as if she was agreeing with me.
