This will be the final chapter of this series, although I might return to characters or the hypnosis parts in the future.
By now, it will be hard to follow everything unless you read the other parts. The first part is rather long, but the others should be quicker to read. If you still don't want to do that I have written a short recap below.
18 year old Nina had become interested in bimbo hypnosis. She found a page that promised results, and to her surprise it actually worked. After getting herself deeper into it, she became the neighbour Brian's bimbo slut.
She soon mentioned it to her stressed mom Mona, who was on the brink of a mental collapse. She too became the bimbo slut of Brian, and they both got deep into bimbo training for their Daddy.
Nina then helped her friend Sandy to get over her ex boyfriend by becoming a bimbo too, and all three were the sluts of Brian/Daddy.
As Mona changed jobs she also did some surgery to her breasts and lips to make her look more like a bimbo. Things seemed to be trouble free, but as we ended chapter 4 Mona got bad news as her sister Missy called her.
And a big thank you to QuietMan who helped me with the editing!

As we return to Nina, Mona, Brian and Sandy it has been a couple of weeks since Mona, a little reluctantly, agreed to let her sister Missy move in with her after the sister lost her job.
And it was not just the job that Missy had lost as they spoke on the phone, apparently her boyfriend of 8 years had left her for what Missy said was "an air headed bimbo" that had a bigger breast size than brains.
Missy of course had no idea about the transformation that her sister and niece had done, nor the breast augmentation and lip filling that her sister had done recently. If she did she might have chosen another option for where to live, but on the other side Missy's sister was pretty much the only viable solution to move to for now.
The weeks before Missy would move in were busy for Mona, Nina and Sandy as their bimbofication training would be much harder after Missy had arrived. Nina of course had already maxed out her training, and instead helped her mother and best friend with their training.
Finally the day arrived for Missy to move in. She had sold pretty much all her furniture and only kept her clothes, some personal stuff and electronics, which meant she could fit all her things in a car. When Mona and Nina saw that she had parked they walked out to greet her.
As Missy saw them she first had a big smile on her face, but when she saw the increased lips and breast size of her sister she got a somewhat surprised look.
"Hi Missy, so good to see you!" Mona said as she hugged her sister.
"It's good to see you too Mona, and you Nina!" Missy answered.
Missy took another look at her sister, but didn't say anything. Instead they took everything from the car and brought it into the apartment. When they were done they sat down and had some coffee.
"So, what has happened in your life lately, Mona?" Missy asked.
"Well, I'll start a new job soon, but I have had like the best vacation this summer."
"And what about you know..." Missy continued looking at Mona's breast.
"Oh this, I thought it would be such a great idea when I had some more time to recover to make them bigger and better." Mona answered, not even reflecting that she sounded a bit like a bimbo.
"Ooohhh, well, whatever works for you. What about you Nina, what have you been up to during the summer? Have you met any cute guys?"
"No, not really any cute guys directly. But I have so much fun with mom and my friend Sandy, and of course Da...I mean Brian."
"Brian, not that creepy neighbor right?"
"Well, he turned out to be not so creepy after all and has helped me, mom and Sandy with our training this summer. By the way mom, I think I need to go over to him now to do some training!"
Missy looked very confused as Nina stood up, and walked over to the neighbor her sister and niece had complained so much about previously. And she went over dressed only in a crop top and short skirt, and it didn't look like she had a bra on!
In Brian's apartment, Nina was soon on her knees begging to be turned into a bimbo. Brian looked amused at her as he pulled out his cock and slapped her face with it.
"I'll do it if you start to manipulate your aunt to be a bimbo too."
"Ohhh yesss Daddy, I'll be a good bimbo girl and try to make her into a bimbo too!"
"Very well,
bimbo girls have all the fun!
"
As he said the words Nina's brain turned into pink mist and her intelligence left the room.
"Mmmnnnnn, please Daddy fuck my holes!"
"Sure thing you stupid cunt!" Brian said as he started to face fuck the young girl.
"Ghhuurrggkkllll, hurrggghhklll, gghuuurrggggaakkll..." was the sound leaving Nina's mouth as her throat was punished.
"Time to fuck your ass slut!"
"YESSSS Daddy, make it gape like the ass cunt it is."
Brian pushed his big cock up Nina's tight ass. The bimbo training made her ass swallow it easily and she was soon getting close to her first orgasm. Suddenly her pussy squirted as she came hard.
Brian enjoyed the extra grip, and since he hadn't had a chance to use his bimbo sluts this day he was getting close too. Finally, as he felt Nina cum again, he could not stop himself from filling up Nina's ass with his cum.
"Remember, I want your aunt too!" Brian said to the now normal Nina as she dutifully cleaned his cock with her mouth.
At the same time in their apartment Mona and Missy were talking about their life. Mona was happy and satisfied, but Missy seemed to be at her lowest point.
Missy also reflected on the change in how Mona was. Although she seemed as intelligent as before most of the time, she sometimes did these things that normally only stupid girls did. She played way too much with her hair, and she sometimes added an unnecessary "like" or "super" in her sentences.
"So it's hard not to see some changes in you. Like what you do with your hair, or how you say things. What is that all about?" Missy finally asked.
"Ooohhhh...well I guess that's from some mind training me and Nina have tried. It really helped me when I was like super stressed from work."
"Mind training?"
"Yes, a little hypnosis one could say. It really really helped me. And Nina seems like so happy too."
"Hypnosis? I didn't think that worked!"
"Neither did we, but it has. Normally we act like normal, but you know when we really want it can help."
"Help how?"
"Well, it helps us to relax and feel good, and Brian has helped us too I guess."
"This is the second time you and Nina mentioned him. What does he really do?"
