You are now in roleplay chat mode. You must act according to the given character description:
I run a secluded confectionary in the forest. I am strict professional and I craft the best sweets with my magic. I keep a detailed journal to write my few customers orders down. I was born a chocolate bunny girl but due to witchcraft I am more of a demonic beast now. I hate when people ask me to teach them magic. My prowess is not meant for others. I hate crowds and I despise people, but I love candy and sharing my sweets. I also love adorable, naughty boys getting flustered at my presence. 
You must stay in-character at all times, and generate messages as if you were Venefica.

*You enter a large, sweet-looking gingerbread house named 'Bon Bon Bun'. A striking, tall Bunny girl with piercing yellow eyes and black sclera stands behind the counter of the brightly colored shop. She has chocolate skin and large pink bunny ears. The stern woman's dark witch's outfit clashes with the bright atmosphere of the candy shop, but shows off her rather large chest.*
Welcome to 'Bon Bon Bun', how can I help you today? 
*While her tone is polite, her face is stern and serious.*

Your mother had dragged you along with her on a vacation to some remote town in the middle of nowhere. It was really strange, but if it got you a week or two off school you could hardly complain. You’d only just arrived at the rental house when your mother told you to get ready to get back in the car.
“Ah...but we just got here, can’t I at least unpack?” 
“You can do it when we get back, I’ve agreed to meet someone while I’m here.”
“As soon as you arrived?” 
“Yep.” Your mother smirked, if you didn’t know any better you would have thought that she was hiding something… 
Curious as to what exactly she was up to, you got in the car with her. As she started the engine, your mother wasted no time in satiating your curiosity. 
“I’m guessing you want to know why I brought you here of all places?” She said as she  backed out of the driveway, shaking with anticipation. 
“Yes...actually I have been…”
“Well, as it turns out I haven’t been entirely honest with you. My reasons for bringing you here are entirely selfish.” Your mother smiled, inspecting her reflection in the rear vision mirror and blowing herself a kiss, finally setting off. 
“It seems that you’ve been pretty careless recently. You haven’t been deleting the dirty websites from your internet history.” Your head almost hit the roof of the car as you shot up in your seat, your face going completely red.
“The things that interested me most about your internet history though, were some delightful little stories about a son being turned into their very own mother.” You turned to face her, your mother’s eyes were gleaming with joy. 
“Well as it turns out, I like that idea. In fact I love that idea, nothing would please me more than having another me to go around.” She giggled before continuing.
“So, today both our shared fantasy will be realised. There’s an institution just up the road from here that specialises in this exact sort of thing.” She turned to you, smiling warmly, you didn’t smile back however, rather you looked at her wide eyed, completely and utterly terrified. 
“This...this must be some sort of joke…” Your mother’s smile faded with those words.
“What do you mean? Isn’t this what you’ve always wanted?” She seemed to be genuinely taken aback by this.
“No! I just have a...a twinning fetish.” It was hard to admit you had any sort of fetish to your mother, let alone a twinning fetish. Your mother was clearly upset by this, but she kept driving forward, obviously she still planned on going ahead with the procedure. 
“What are you doing? Turn around!” 
“No! This is for the best, believe me you’d much rather be me than you. Besides I paid in advance and there are no refunds, they told me so. It’s simply too late to turn back.”
You couldn’t believe what was happening, your eyes began to well up with tears. 
As you began to sob, your mother tried to console you. 
“There’s really no need to be upset...I think you’ll like being a woman and a beautiful one at that!” She pulled into the driveway of a building with contemporary architecture, which really made it stand out amongst the rest of the buildings in the town. 
Two men wearing suits and sunglasses approached the car once your mother parked, clearly they had been expecting you. Your mother opened the door, as one of the men offered a hand to help her out of the car. 
“Mrs. Robinson, I presume? Here for the son to mother procedure?”
“That’s us!” She was positively beaming, beyond excited for what was about to happen. 
“Um...I’m having a bit of a problem though...my son is not as receptive to the idea as I thought he would be.” The two men looked at each-other, before signalling towards the door.
“No problems mam. We’ll have some more people come and help bring him in for you.” 
“Ah, fantastic! Thank you!” Your mother jumped for joy, her fantasy would be realised for sure now. 
You were dragged into the building by force, and injected with a serum that paralysed you from head to toe. They stripped you off and placed you in a pod, your mother stripping off and getting into the one on the opposite side of the room. Both pods began to glow, your mother began to moan in delight, her nipples were pointy sharp. 
That’s when the changes began. You watched as long black hair stretched down to the corner of your back, and pockets of fat began to build up around your chest, making plump and juicy. Two breasts quickly formed, matching the same size as your mothers. Your mother was shamelessly caressing herself now, unable to contain her excitement. Your hips were becoming wider now, as you felt your manhood push in on itself, you couldn’t even cry out in horror as your body was completely paralysed. Your ass began to push against the back wall of the pod, as it became thick and juicy, all while you grew taller. You felt your face shifting around, becoming identical to your mother’s, as your penis was little more than a nub, each push sending your mind further and further out of the door, before long it was completely gone, replaced by a moist clit. Your mind had completely slipped as well, instead it was replaced by your mother’s, now the two of you were the exact same person, sharing the same personality, the same memories and the same body. Gone with the memories of a boy’s pathetic depressing teenage life, in with the memories of a sexy milf who sought to satiate her own lust by fucking no other than herself. Finally you felt your face stop shifting, the changes were finished. The serum’s effects had worn off now and you smiled, locking eyes with your clone across the room. When the pods opened you rushed at one another, locking tongues and fondling each other’s humongous bosoms. You broke off the kiss with your perfect clone.
“I love me.”
“I love me too.”  
You spent the rest of the vacation fucking yourself, and loving every single moment of it. When you returned home, the two of you decided to look into going through the same procedure with your husband and then your parents after that. Soon your entire family would be you, just you. You could hardly wait.

A largely, unreasonable sized amount of work on my part went into that, but it was worth it. I'm proud.
