Dominating MIL

Chapter 133—Their First Experience

A few days had passed since Yeonhee and Yeonji had their assholes developed.

With the help of their expert (?) mother-in-law, they quickly learned to use their assholes like pussies. They were becoming faithful female slaves faster than expected.

On Friday morning, my mother-in-law said with a lewd smile, "It looks like the time has come, Master."

"It's about time you taste my daughters' anal virginity to your heart's content."

"I understand, and you've finished preparing that, too, right?"

"Yes. It's about time we tell Yeonhee and Yeonji about Ahjung."

My mother-in-law smiled, thinking about offering her two daughters' last remaining virginities to me and revealing that her friend was also my female slave. She waited for the evening with an even lewder smile.

.........…

"Is it today, Unnie?"

"Yeah…"

Yeonhee and Yeonji were on their way home after finishing work and school.

As usual, Yeonhee was driving while Yeonji sat beside her, chatting with her.

They had overcome the awkwardness that once existed between them and had grown close again, now bonded as Joohyun's sluts. Recently, their relationship had become as warm and natural as it was in their childhood. However, today, the mood inside the car was unusually tense.

It wasn't due to any argument or falling out. Instead, they were both nervous and shy about what was going to happen that night—the moment they would offer their last virginity to their master.

Unless overwhelmed by arousal or deep desire, they experienced embarrassment and hesitation like anyone else. Now, both were blushing at the thought of what the night would bring.

"This makes us more like Mom, doesn't it?"

"Yeah… Mom has already given everything…"

Yeonhee and Yeonji thought of their mother, Jeongyeon—someone they deeply loved and respected. A faintly lewd smile spread across their faces.

It was something they could never have imagined before. But recently, they had come to understand a different side of their mother—perhaps her true identity as a slut.

At first, the discovery had shocked them both.

Over time, however, they came to accept that they, too, were sluts just like her. Through their shared training under Joohyun, they gradually embraced their roles and identities.

As they became more attuned to their lewd desires, their respect and love for their mother deepened even further.

"Come to think of it, I think I've kissed Mom more than Joohyun. That's a bit embarrassing."

She had only kissed Joohyun during sex and while she was being trained. However, she also kissed her mother and Yeonji daily at his request.

Just before Yeonji got in the car, they greeted each other with a deep kiss, exploring each other's tongues. It was now completely normal, so she didn't think it was strange. But if she thought about it, it was a very strange situation.

"But I like it better now... ♥"

When Yeonhee first found out she wasn't the biological daughter of the family but had been adopted, she felt an overwhelming sense of distance—from her mother, from Yeonji, and from the family as a whole.

For a long time, the belief that they were only family in name haunted her. But now, those feelings had faded. She truly felt like she belonged.

"Even though it's embarrassing… I'm still looking forward to it♥"

"Yeah… me too♥"

They had already seen every part of each other. In just a few weeks, they had grown even closer than they had in the past twenty years.

Their bond had deepened because they had opened themselves up completely, without hiding anything.

With a mix of nervousness and excitement, they returned home—where their mother, Jeongyeon, was waiting for them.

"I'm home, Mom…Haaah♥ Kiss ♥ Mmmph ♥…Kiss♥"

"Welcome home, Yeonji… Haaah♥….Kiss♥"

Seeing the mother and daughter kiss and continue kissing as soon as they entered the house was different from before.

Rather than smiling and greeting each other before going to their rooms, they greeted each other with a deep kiss that made their saliva flow. They had grown closer, both mentally and physically.

"Yeonhee, come here too♥"

"Yes, Mother… Haaah♥ Kiss ♥ Kiss ♥ Mmmph ♥"

Yeonhee's face was slightly flushed, but greeting her mother with a deep kiss was now a normal part of her daily life, so she didn't hesitate.

"Just from kissing, my pussy is already wet ♥"

Like a pervert bitch, Yeonhee's body was automatically aroused just from kissing.

She had developed to the point where she could easily climax from a deep kiss with Joohyun.

She had changed so much that she was a little unfamiliar with herself, but she accepted that side of herself and was happier.

"Haa... Both of you remember that you're offering your anal virginity to your husbands today, right?"

""Yes♥""

"Then today, you're offering your dirty assholes to your master, so you have to be more polite♥"

""Yes♥""

As they listened to their mother's instructions on how to act in front of their master, the sisters' bodies heated up. They were to act not as daughters, but as female sluts.

"Now, both Yeonhee and Yeonji are becoming proper female slaves of the master."

"Yeah... I'm becoming a woman that Oppa likes, hehehe ♥"

"I will do my best to become a slave that Master Joohyun can use my body to his satisfaction."

These were words that others might never understand, but to the three women, they meant more than anything else.

"Alright, let me check one last time… both of you, hold out your butts♥"

"Okay! Here you go♥"

"Here you go♥"

Even though they were standing in front of the entrance, the sisters lifted their skirts and lowered their panties without hesitation.

The anal plugs in the shape of hearts embedded in their asses were then revealed.

 Squish… Squish… Squish… Squish…

Squish… Squish… Squish… Squish…

"Aahhh♥…Hnnng♥…Haaang♥"

"Aahhh♥…..Haa♥...Aahhhh♥"

When Jeongyeon grabbed their anal plugs and moved them in and out, they glided smoothly, stimulating their insides — unlike before.

"Now, you can call them pussies. Both of you have worked hard these past few days."

"Yeah! It's all thanks to Mom."

"Thanks to Mother, our asses could become anal pussies ♥"

The sisters smiled happily at each other.

Their mother, who was also smiling at them, got up from her seat.

"Then, shall we prepare before this husband arrives?"

""Yes♥""

They still had time before offering up their last remaining virginity, but as diligent female slaves, they prepared in advance to ensure their master would have a satisfying time.

[MV POV]

"Welcome home, Master♥"

"I missed you, Oppa♥♥"

"Welcome back, Master Joohyun ♥"

When I came home after finishing my shift at the café, I was filled with energy the moment I saw the three women waiting to welcome me.

Now that Yeonhee had been fully trained as my woman—as my daughter—there was no longer any need for restraint.

I could finally treat them all freely, as my own women.

Squeeze…

"I'm home."

"Aahh♥"

I grabbed my mother-in-law's ass. She was standing closest to me and showing it to her daughters. They didn't find it strange at all. Instead, they smiled happily.

"Hehe♥ We're almost finished preparing today's gift for Oppa♥"

"We'll do our best to make it something Master Joohyun will be pleased with♥"

"Alright… I'm looking forward to it."

I already knew what the gift was, so I gazed at the sisters with growing anticipation.

They looked no different on the outside, but the sisters, who had developed their assholes like my mother-in-law, seemed more seductive than usual.

"Are they becoming like my mother-in-law? I feel incredibly turned on..."

The sight of the two of them exuding the mature female aura of my mother-in-law or Ahjung Ajumma—who could arouse men just by being around them—made my dick hard.

"Hehe. It seems like Oppa is looking forward to it too."

"We'll make you feel great tonight, so please be patient for a little while."

Slide... slide... slide...

As they told me to be patient, the sisters slyly put their hands on my crotch and stroked it, seducing me.

"Both of you, wait a little longer."

"Yes... ♥"

They immediately answered my mother-in-law and took their hands away, but their faces clearly showed their disappointment.

The sisters were holding back because tonight, they would offer up their last bit of virginity and become even more lewd female slaves.

'I have to hold back too… Haa…'

Naturally, I needed to wait until tonight, so I felt a little disappointed. But after seeing Yeonji and Yeonhee, I decided to be patient. I spent the time taking a shower and relaxing as usual.

"Where is Ajumma?"

"She's waiting in my room right now♥"

As the night deepened, I asked my mother-in-law—who had come to my room first—about where Aunt Ahjung was. She told me that Ajumma was in her room, just next door.

"Tonight is the night Master receives my daughters… But it's also the night my daughters receive my friend♥"

Over the past few days, my mother-in-law and Ajumma had talked things over and come to a decision. They planned to carry it out tonight—without the sisters knowing.

We had prepared an unforgettable gift for the lewd sisters, who were excited to offer their anal virginity to me. I waited for them.

Soon after, Yeonhee and Yeonji entered my room, their smiles carrying a subtle mix of shyness and politeness.

"Both of you, come forward."

"Yes♥"

My mother-in-law also adopted a slightly serious tone as she instructed the sisters to come closer. Without hesitation, the three women knelt on the floor and looked up at me.

Their behavior was formal yet gentle, as if they weren't here as my mother-in-law, lover, or sister, but simply as my women—my obedient slaves.

"Then please take my daughters' anal virginity today, Master, and make them your fuck toys."

I got hard watching my mother-in-law—the sisters' own mother—beg me to violate her daughters and treat them like bitches.
