Dominating MIL

Chapter 129—Developing

While Joohyun was at Ahjung's house, behaving like a strict, dominant husband and issuing commands, Yeonji and Yeonhee were busy preparing something in the mansion's spacious bathroom.

"This is so embarrassing…"

"I know, but it's an order. We have no choice."

"Still…"

Inside the bathroom, the naked sisters stood before a basin filled with pink liquid and a large syringe.

Yeonji blushed and hesitated as she looked at it, clearly embarrassed. Yeonhee felt the same way, but she kept a stoic expression, hiding her discomfort. After all, it was a direct order from their master, Joohyun.

"If we play this…"

At first, their mother, Jeongyeon, had tried to explain it to them in person. However, the girls were too embarrassed to listen. As a last resort, she recorded a video instructing them to perform the jelly enema together.

Although they were in the bathroom, a large TV had been installed there. When the video started, Jeongyeon appeared on the screen.

–Are you both watching closely? Then I'll explain how to do the enema ♥

The sisters watched their mother on the screen. Despite the awkward nature of the topic, Jeongyeon appeared cheerful as she explained the enema process to her daughters.

Reluctantly, the sisters began to listen to her instructions.

– There's a pink liquid and a syringe in the basin, right? Fill the syringe completely, then put it against your anus and press hard. It's that simple♥

"F-fill it completely?…. Uuu…."

The syringe looked like it could hold over a liter when full. Just imagining it being completely filled brought tears to Yeonji's eyes.

She had been excited about offering her asshole to Joohyun, but it seemed that the act of an enema was embarrassing even for her.

'If I clean it with this, Daddy will♥…. Haaah♥…..'

Yeonhee was feeling embarrassed, but she felt it was more important to be praised by Daddy for serving him with her asshole. She was prepared and excited to serve Daddy with a hole she had never used before.

– Before inserting it, make sure to loosen your asshole thoroughly with your fingers. If you don't, you might hurt yourself.♥

""Yes~""

They answered their mother on the screen and tried to touch their buttocks, but Yeonji hesitated and couldn't do it properly.

When she was in "bitch mode" in front of Joohyun, she didn't care about embarrassment. However, unless she was extremely excited, she was hesitant to act lewdly in front of her mother or sister.

 "If you can't do it, I'll do it for you."

"B-but it's my asshole…"

"It's okay. Considering Joohyun's personality, it's obvious that we'll be doing more lesbian play and asshole training in the future. It wouldn't hurt to get used to it beforehand."

 "Uuuu…. Okay…. H-here♥"

Persuaded by Yeonhee's words, Yeonji finally asked her sister for help because she couldn't loosen it herself. She got on all fours and presented her ass.

"This is Yeonji's asshole. It feels kind of sexy."

It was Yeonhee's first time seeing her younger sister's asshole, but it didn't feel dirty or unpleasant. Instead, it felt sexy. She slowly reached out her hand.

Squish… Squish…

"Aahhh♥ S-softly sister..."

"Okay, I will♥"

Squish...Squish...Squish...Squish...

She gently rubbed her wet hand against her asshole and tried to insert it, but the hole was tighter than she thought and wouldn't open.

Even though she hadn't inserted more than a fingertip, Yeonji's asshole was twitching and visibly getting wet.

'She's embarrassed but excited♥'

As a fellow masochist, Yeonhee could relate to Yeonji's feelings. She slowly moved her hand, widening the asshole. Yeonji's body began to twitch and emit lewd moans.

"Haaang♥... Aahhh♥... Aahhh♥. It feels weird, sister."

"Your asshole is gripping my finger tightly right now."

"Haaang... ♥ No, it's not."

Yeonji denied it, embarrassed, as her sister stirred her asshole with her finger. However, the lewd moans coming from her mouth and her increasingly wet pussy revealed her true feelings.

"Then I'll insert it more."

Squish….

"Aahhhh ♥! D-deep!"

Yeonhee inserted about two finger joints deep, but it was Yeonji's first time, so she wasn't used to it.

Nevertheless, Yeonhee seemed to be enjoying it and kept poking the hole.

"Aahhh♥… Haang♥… Aahhh♥… N-now…."

"Then that's enough."

"Eh?! Why!"

Yeonji's asshole was gradually loosening up, and she was about to reach climax when Yeonhee stopped her. She puffed out her cheeks and looked at Yeonhee in protest.

"The purpose now isn't masturbation, but cleaning it up..."

"Uuu... Okay! Then I'll loosen up your ass, sister."

"No, I'll do it myself... Kyaa!?"

Yeonhee had been planning to loosen her own asshole when Yeonji attacked her, seemingly in revenge for stopping her right before her climax.

"In this position!"

Squish… Squish… Squish…

"Aahhh... ♥"

Yeonji laid Yeonhee down, making her take a position with her ass facing up. It seemed as if she were getting revenge, but Yeonhee seemed to enjoy being humiliated like this. She accepted it without any resistance.

"Ah ♥Aahhh ♥ Not only am I in this lewd position in front of my younger sister, but my asshole is being poked too."

She had felt excited when Daddy toyed with her, but being toyed with by her younger sister made her feel even more depraved.

Squish… Squish… Squish…

"Aahhh♥"

"Hee~♥ Sister's asshole is easier to enter than I thought?♥"

"Aahh♥… Aammm♥… Actually, I've masturbated a few times with my asshole…. Aahhh♥"

"Really? I thought you were someone who didn't masturbate, but… You're a pervert like me and Mom♥"

Slap!!

"Aahhh♥"

Pussssss...

"Hehe♥ You squirted pussy juice♥"

Yeonji seemed to enjoy teasing and tormenting her sister. She inserted a finger into her anus and played with it. Yeonhee climaxed, revealing a new lewd side of herself. Yeonji laughed, enjoying it.

"Ah! You can't cum~ that's cheating!"

Squish… Squish… Squish…

"Ooh! Wait, sister! You can't cum! Oooooot!"

As if punishing her sister for cumming alone, Yeonji tormented her asshole even more persistently. Yeonhee's pussy melted with pleasure, dripping with juice.

"Oooooot!"

Pussssss....

She climaxed again shortly after, squirting pussy juice. Her younger sister now knew that she was a premature cummer.

"Hehehe... This is kind of fun."

"Aahhh... ♥ Haang... ♥"

"My younger sister has turned into an S."

Yeonji, who had always relied on and respected her sister, watched as she was poked in the asshole with a finger, toyed with, and quickly climaxed, her body trembling. She felt like she was awakening to a certain tendency within herself.

It was still in its early stages, but Yeonji enjoyed the new excitement and finally let her sister go after she climaxed three more times.

......…..

"Seriously… You wasted so much time."

"Hehe… Sorry, sister."

After about an hour had passed, Yeonhee and Yeonji finally collected themselves. They got back into position to resume what they had been doing.

"But I only tormented you for 20 minutes, and you squirted 8 times…."

"T-then, let's continue the video."

– If you've loosened your assholes enough, fill the syringe with the liquid as I said before and insert it into your ass… Well, since you're beginners, let's fill it twice each♥

"T-twice!?"

"…..Aahh… Yeonji, do you want to go first?"

"Uuuu….."

The sisters seemed hesitant when their mother told them to fill it twice and insert it into their assholes. Even inserting it once was difficult.

"Then I'll go first. Yeonji, please insert it for me."

"Okay..."

Since it would be difficult for beginners to do alone, they decided to help each other and got into position.

Swoooosh….

"Aahhh♥..."

Yeonji brought the syringe filled with liquid to her sister's asshole and pressed it, watching as the liquid filled her insides. She was feeling excitement with an unknown emotion.

She knew it was her turn next. Despite her fear and anticipation, a small smile appeared on her lips.

"I inserted it twice."

"Haa♥….. Haa♥... Aahh♥.... Haa♥…. O-okay…. This time, I'll insert it for you♥"

"U-uh....♥"

When it was her turn, Yeonji got on all fours and presented her asshole.

Swoooosh…..

"Haaah... C-cold♥"

The sensation of filling the asshole was completely different from the sensation of inserting something into the pussy.

 "I inserted it all♥"

"Aahhh♥….. Aahhh♥ It's p-painful♥"

Each of them had used the syringe to insert the liquid twice into their asshole.

Though the sisters clutched their stomachs and flinched as if in pain, there were faint smiles on their faces.

"H-how long…. Haaah….. ♥ do we have to endure it?"

"Haa… Haa... ♥ J-just a moment…."

They felt like they were about to cum but knew they shouldn't do so right away, so they quickly replayed the video.

– If you've inserted everything into your asshole, you have to endure it for about 30 minutes.

"T-thirty minutes!?!""

Even though they were masochists who liked pain, they didn't enjoy enduring this kind of pain for 30 minutes.

If Joohyun had ordered them directly and was standing in front of them, they would have endured it with the determination to die. However, they weren't as excited now, so the pain felt quite intense.

– If 30 minutes seems too long, there's a way to make the liquid turn into jelly faster inside.

"P-please tell us quickly♥"

"I can't endure 30 minutes♥…."

The sisters, while enduring the discomfort, continued watching the video of their mother.

– That is… to make the jelly harden faster with your body heat, you just have to do the slutty sow dance for 10 minutes♥

For the first time, the sisters felt a sense of sadism from their mother's smiling face. They immediately got up and...

"A-a slutty sow dance♥"

"I want to dance too♥"

They began to do the vulgar, slutty sow dance.
