At Breakfast the following week, Kenzo announced, “Yesterday, I finalized a bid with a partial payment until settlement on a Mediterranean style Mansion estate in Palo Cedro, up in Northern California
We’re running out of room. As it stands now, we have no room to add family members. All the bedrooms are used. What happens when I knock all of you up? That’s four kids to consider. Then we have Mei Ling and her baby. For six. I would hope that if Kioko, with my help, can seduce Ms. Claudette Marin, we’ll add a cunt slave teacher to our harem and get kid. That makes. That’s twelve people. I would really like to see Hikari come out of her shell and bring in a new slave-slut to the family.
“So, I bought the eighteen-acre lot to build a mansion with twenty bedrooms and thirty bathrooms. The grounds have horse stables, pool, tennis courts. Walking and bike trails. It’s about a twenty-minute drive from Redding.”
Midori asked, “If I may. Master, how much is all of this?”
“Got the package for a steal at $16 million. Any girls we add will need to either move with us, or go their own way. The move will take place during the school summer vacation.”
Once we move into the new house, you girls will be going to Foothill High School. After you graduate high school, you’ll go to college online.”
As the girls ate breakfast, they stared at each other in disbelief. Suddenly, Kenzo changed topics. He turned to look at the girls and said, “Every one of you little hotties, give me your panties.”
Kioko and Hikari looked at Mioki who had a smug look on her face. Hikari asked her, “What are you so smug about, your Highness?
As Mioki handed over her panties she retorted, “I have someone to lick me clean after I pee. Neither of you do.”
Hikari shook her head and replied, “Ain’t that a bitch? I gotta get me one of those. On the other hand, you’re the queen. Find me one ... please?”
“You got it, Sis.”
Kenzo added, “Mioki, don’t be showing off that royal pussy today, got it?
“Yes, Daddy.”
“You other two cum sluts? You hafta flash two people during school hours. Got it?”
The two cum sluts grinned and answered, “Yes, Daddy” with ear-to-ear grins and exaggerated nods.
Hikari giggled and looked at Kioko, “Cheezie-Peezie! My pussy is starting to juice up already!”
“Mine too!” Kioko retorted.
“Alright you girls,” Kenzo butted in, “finish eating and get ready to leave. Don’t forget. Depo shots tonight. Mioki call Mei’s mom and tell her you’re bringing your slave home for dinner. She needs to have the shot also.”
They were just walking out the door what a FedEx driver pulled up. Mioki squealed and exclaimed, “Oh. “Goody, goody, goody! Mei Ling’s collar is here!”
Mioki signed for the package and yore it open. It was in a velvet case and the leash ring was in place with the heart-shaped name rag the read:
Property
Of
Mioki Yakamura
Mioki’s sisters both “Ohhh, that’s nice!”
Happy, Mioki remarked, “it looks better in person than in the picture!”
Kioko asked still disbelieving, “And her mom actually give you permission to collar her?”
“Unbelievably, yeah. She actually said, ‘You have my permission to collar her.’”
Hikari said, “After you collar her, send us a pix. Can I use her?”
“Don’t worry, everyone’s gonna get a turn.”
They got on the bus and continued their conversation. Once at school, they each went their separate way to their locker. Since the day they met, Mei was waiting by Mioki’s locker. The first thing Mioki noticed was that she was wearing a skirt like she was instructed. After the morning greeting, Mioki got her books and said, “Follow me, my little fuck bunny.”
Mei giggled.
They were headed to the nearest girl’s room, but along the way, Mioko pulled Mei into one of the empty music practice rooms. She first told Mei to lift her skirt so she could verify if she’d shaved her pussy. Mei had a very compact pussy with thin, sleek outer lips that still hid her inner folds. The very tip of her button barely peeked its head out. Mioki ran two fingers up through her slit and brushed over her clit. Mei gasped a tiny peep then blushed. Mioki whispered, “My dear, sweet Mei. You have a very beautiful pussy. And who’s beautiful pussy, is it?”
“It’s your Pussy, Mommy.”
“That’s right. It’s mine. Now, kneel. Do you come to me to kneel and give yourself totally and completely to me?”
“I do give myself freely to you completely.”
Mioki pulled out the velvet case and showed her the collar.
She then put the collar on her, pulled Mei to her feet and kissed her deeply and passionately. She lifted her skirt and ordered “Taste me. Taste your Momma’s cunt. From this day forward you will call me mommy in private and also in front of your parents.
“Yes, Mommy.”
“It is too dangerous to promote your slavery at school. I did some research on the internet. Legally, under Tinker v. Des Moines standards, schools can ban it if it materially disrupts learning, which it almost certainly would.” She slipped the name tag off and handed it to Mei. “Don’t lose it.”
“Now stand. From now on, you hook a finger in my waistband or a belt loop on my pants. But you stay connected to me and a step behind. Do you understand?”
“Yes, Mommy, I understand.”
“Okay. Let’s go to homeroom.”
As they walked the hallway to homeroom, it seemed a little suspicious to see two Asian girls walking so close together. As they passed Mr. Hamilton, their homeroom advisor he spoke. “Miss Yakamura, Miss Chang stop! What the meaning of...” he was waving his hand like he didn’t know what to do. “ ... this?”
Mioki turned and asked, “Meaning of what ... Sir?”
“That collar.”
“Mr. Hamilton, it’s not a collar. It’s a necklace. Actually, it’s a very expensive piece of jewelry.”
Mr. Hamilton looked skeptical, but had no rebuttal. “Sit down both of you.”
After roll call, the bell rang and the girls headed to English. At lunch, Mei was so overwhelmed in her feelings of love and affection for Mioki, the way she has had to humble herself walking with her head lowered, finger hooked into her Momma’s waistband, she expressed her feelings.
“Mommy, I’m so very, very happy to be your slave! I love my collar, and the way you make me go without panties, shaving my pussy and walking humbly behind you has my cunnie dripping my love juice for you down my thighs! I can’t wait to be used by you!”
Except for some odd stares, the rest of the day was uneventful.
At Mioki’s locker at the end of the day, Mioki put Mei’s name tag on her collar before she went outside to wait for Kenzo to pick them up. Ten minutes later, he arrived. All four girls got in the SUV, and Mioki introduced Mei to her mother. Midori fell in love with Mei. Speaking about Mioki collaring her, she asked the little teen, “You will be one of my daughters and one of Kenzo’s fuck toys.”
Mei smiled and answered, “Yes, Okasan. I am very happy to belong to my new Masters.”
Midori looked at Kenzo and said quietly, “I can’t wait to taste her pussy and drink her pee!”
Mei turned pink, the girls just giggled.
Mei whispered to Kioko, Master Kenzo is really hot! I never would have thought a man that gorgeous would have me.”
Kioko giggled and said, “By the way he’s checked you out he’s dying to eat and fuck you!”
Mei slapped her arm and giggled. Mei was visibly happy to become a member of Kenzo’s harem, and the Kenzo family embraced her as one of their own.
After dinner, they dropped Mei off and headed home. As soon as she walked in the door, Mioki’s phone rang; it was Mei’s mother. “Hi, Mioki, I just had to call you and tell you how pleased I am with your taste in jewelry. Mei’s collar is simply beautiful. And that name tag? I just think it is so cute!”
“Why, thank you Mei no okāsan [Mei’s mother, honorific]. I am very happy you are pleased with it. I have a question, no-- several questions. Why did you make Mei shave her pubis?”
“Thank you for your question. I made her shave as a token of her personal humility to me her Master mother.”
Ying Na inquired. “As her birth mother. I would like to know ... are you two entering an intimate Lesbian relationship?”
“What did Mei tell you?”
“Well, I assumed that when you said you would collar her, she would identify herself as being submissive to you,. I assumed you two were professing a Lesbian persona.”
“Mei no okāson, you are correct. Mei will become my lover. I will be using her for my pleasure. Do I still have your permission to watch over Mei as her intimate, loving Mistress? I see it almost as a motherly protective, yet personal relationship. That is why even in your presence, she will address me as Mommy.”
“I am so relieved that a girl such as you has taken such a personal interest in Mei. I have spent many a sleepless night worrying about her doing something stupid behind the bleachers or some storage room and getting pregnant. She has, from an early age displayed many overt signs of submissiveness that I feared she would be in danger. She has also at times been uncontrollably ... how do you say ... bratty and disrespectful. But I can see she is well taken care of, and happy in her affections and submission to you. You have corrected her behavior overnight! It’s so incredible! Please do continue with my blessing to love her and train her.”
“Thank you, Mei on okāson very much. That means a lot to me. As for her getting pregnant, you needn’t worry, I can guarantee that.”
“How thoughtful. You have my utmost faith in you to act in her best interests. Enjoy the rest of your evening, Mioki. Good night.”
“Goodnight to you also.”
After the call, Mioki revealed her conversation with Mei’s mother and her complete acceptance of Mei having an intimate relationship with her. She was also well pleased with Mei’s collar. All seemed well in the Yakamura household.
Kenzo said, “You need to put a collar on her and her Mei’s sister too.”
They discussed the upcoming weekend’s activities. Saturday morning, Kenzo and Kioko would pay a visit to Claudette Marin’s residence. It would not take long to ascertain whether the very pretty math teacher would become an addition to Kenzo’s harem. AND ... Mei Ling would spend the weekend partaking of the intimate “delicacies” of Yakamura familial affection.

Saturday morning at 10am, Kioko and Kenzo were standing outside Claudette Marin’s apartment door while Mioko sat in the SUV. As soon as the status of their meeting was determined, they would go by and pick Mei up for the weekend at Mioki’s.
Claudette answered the door in a diaphanous pink negligee and robe. She was initially shocked, and looked both startled and angry at Kioko when she saw the tall man standing next her. She asked defensively looking at Kenzo as she closed her chiffon robe, “Who are you?”
Kenzo began his sales pitch. “Good morning, Miss Marin. I’m very sorry to startle you. May we come in? There is a matter of the utmost priority to discuss.”
Claudette stepped aside and invited them inside. They moved to the living room and sat. Kenzo wasn’t going to waste time tip-toeing around the burning bush. “Ms. Marin, I am Kenzo Yakamura, Kioko’s brother and legal guardian.”
Her eyes fell thinking she might be going to jail.
“We both know why Kioko was invited here to your home. It may surprise you to know that you are in no trouble with me or Kioko. I am about to make a you a proposition that would result in a win/win for all parties involved here. I’ve done some investigation and it’s pretty evident that you have an affinity for young girl pussy.” Kenzo held up his hand to stop her from interrupting him. “Don’t get defensive or feign indignance. You were under suspicion for improper conduct at your last school in Colorado. Now ... what you don’t know is that I am the lone male—a very dominant male, I might add—in the Yakamura family.
“I am the dominant Master of my house. My mother, Kioko and her two sisters are my sexual slaves. If you are amenable, I am inviting you to move in and become a part of our family. The immediate result is that you become my sexual slave and a member of my harem. Second, you will have full consensual availability to Kioko and her sisters, who are 14 and 16. In return, you will occasionally furnish me and my family preselected and agreed upon, as one might say, ‘fresh meat’ for all to share and partake of. You will live as a family member. Meaning. I pay for all living expenses, and you contribute a portion for food and incidentals such as sex toys, or other paraphernalia.
We share each other, accommodating and respecting each person’s needs and kinks. All my females are submissive, of which you would also be required to be. We can discuss your kinks later. But all are into both hetero and Lesbian sex, humiliation, light bondage, spanking and watersports.
If you agree to move in within the next thirty days, you may partake of Kioko’s charms for the weekend. I’m sorry but family are the only people we share ourselves with. It’s only a formality, but you would also need to grt tested for HIV and STD’s. So ... there you have it. My cards are all out on the table. Oh. if there is any lease breakage fee, I will pay it. So, what you think?”
Claudette chuckled. “Is this for real? I can move in and play with all three girls?”
“Yes, but there is a hierarchy. Mioki, the fourteen-year-old is the queen of the house. You obey her as you would me. Kioko is my Mistress, she is the number two lady of the house, Hikari is my first concubine and number three lady. Mioki’s slave Mei is number two concubine and you would be my number three concubine. Last is Midori, the girls’ mother, is the simply the house cum-slut. Any questions?”
“I’ll do it. I’ll become number three concubine, and as you said, I can keep Kioko for the entire weekend?”
“Yes. You bring her home by 8pm tomorrow night. She needs to get ready for school. One last item. All my women are shaved bare every three days and I own all their holes including yours.”
Nodding she replied, “I thought as much. I agree to your terms. What about my furniture?”
“If you move in immediately, I will have a moving company pack you up and put your furniture into storage. I just an estate mansion in Palo Cedro, California and we will definitely need more furniture. Are you amenable to relocating?”
“Yes Sir. There is always teaching positions pretty much everywhere. I’ll pack up my personal things this week and move in next weekend.”
Kenzo stood saying, “Sounds like a plan.”
They shook hands on the deal. He added her about birth control and she said her period was due in two weeks; she was in the middle of her cycle, and was probably ovulating. Therefore. no vaginally intercourse for two weeks. He said that was fine. She’d get the Depo shot five days after her period ends.
He headed for the door and told Kioko, be a good little fuck toy for her sister, she now part of the family. You two can switch Dom positions to suit each other this weekend. Enjoy!”
He then left.
