Coco looked down at the dress Rarity had just made for her. It was cute, with blue frills and contoured to the proportions of her slightly masculine body well. Since she had just begun her transition, Coco had only just started hormone treatments, namely Spironolactone to kill her Testosterone and male sex drive, and Estrogen to help her become more and more feminine.

"It looks wonderful on you, Darling." Rarity chirped, happily glancing all around Coco's figure, "Exactly how I imagined!"

Coco sighed, feeling that her supportive girlfriend was lying to her. "Even if that's true Rara, it doesn't change the fact that I am still overtly masculine. Just because I was gifted with a naturally female-sounding voice doesn't mean that I pass perfectly. These medications are going to take a long time, and there are days where I still don't feel like..." She abruptly trailed off, looking at her blue-painted toes.

"What Coco? What don't you feel that you want to be feeling?" Rarity asked, cocking her head to the side.

"...Like a real girl. At least not like I want to be, a dainty little princess." Coco finished.

Rara chuckled. "Coco dear, I will endeavor to help you be the cute little princess you want to be. Your height is already in your favor after all, you're so cute at only 5'1!"

Coco blushed, hard, "Thank... thank you Rarity. That really helps."

"Don't mention it Darling. Give me some time to prepare, and come meet me in the other room in a few hours, okay? Oh, and go take your medicine like a good girl."

Coco nodded and went over to the shelf, where she carefully took the hundreds of milligrams of Estrogen along with the anti-Testosterone pills. She swallowed them, with a nice gulp of clear cool water. She looked down at her penis, about 2 inches in length when hard, although she rarely had erections anymore already thanks to taking her pills for two months. It was only thanks to Rarity and her connection to Princess Twilight that she was able to get them so easily, and the medication was already powerfully affecting her body.

While still somewhere between conventionally Male and conventionally Female, she had begun to grow small breasts and her voice became higher than it already was. Her sex drive had gone down to almost zero, so after Rarity had let Coco mount and fuck her once, she had been a pure anal bottom ever since. Rarity said she didn't enjoy *being* penetrated anyway, and Coco would soon loose her ability to do so, so it worked out for both of them soon enough.

The young girl walked over to her girlfriend's couch, sat down, and set up her pink laptop to entertain her while she waited for Rarity's next move.

Coco finished her video, a particularly nice one featuring a massive white cock entering a submissive black girl's pussy and thrusting in and out. Coco always put herself in the position of the woman in porn, ever since she had started viewing it at a young age.

She gently rubbed her nipples and one hand fingered her ass-pussy, just like Rarity taught her. Just then, she heard the aforementioned woman call for her, and Coco got up, pulled up her panties, and went over to her. They were slightly wet from prostatic leakage it seemed, and Coco realized she was indeed very aroused.

"Well, well, well. Looks like my *girl* has been playing with herself while I've been busy!" Rarity chuckled, staring at Coco's blue panties with her little clit slightly bulging out of them.

Coco blushed again, perhaps even harder than earlier. "I'm just really excited, okay? Plus I had to do something to pass the time!"

"It's all good, darling. You didn't touch your clit, yes?"

"No, Rarity, I didn't. TO be honest with you, I haven't really since I was a little... girl. I've almost always masturbated with my nipples or anally." Coco replied, looking off to the side. She noticed that Rarity's comfortable and elaborate bedspread was equipped with a spot for her to lay her head at the end of the bed, and Rarity herself had changed her outfit from the usual to a female Doctor's one. It looked very nice, and the white fabric revealed enough of her cleavage to make Coco's clitty leak again, and would have made any Man gain a full erection.

"Um, what is all this?" Coco asked, turning back to face Rarity and wait for her response.

Rarity smiled. "I'm glad that you asked. You see, when you talked about how you still felt slightly masculine at times, I had the perfect idea. In addition to your hormones and the wardrobe changes I've helped you make, I can also hypnotize you to feel more female and even give you certain... genitalia "equipment" to help you hide your clit!"

"You can... you can really do that?" Asked Coco, highly intrigued by the offer. Hypnosis was something she had never thought of before, but she knew Rarity was into it both sexually and had also studied it when she was considering becoming a psychiatrist.

"Of course I can, my darling Coco. With enough suggestion and effort, I can make you feel any way you or I want! You'll have to trust me of course, but I promise you that I will not harm you. At most, with your full consent, I can go beyond the original plan that I had and help change your memory of your childhood into a more traditionally female one. Less fellow male socialization and more playing with dolls or whatever else would help you feel more at home with your gender."

Coco practically had stars in her eyes. "That's amazing Rarity! All of that would be perfect! Please help me be a traditional feminine girl~!" She hugged her girlfriend as hard as she could, although Rarity didn't feel any pain due to Coco being naturally weak and affected strongly by the hormones.

"That's wonderful, darling. We shall make you into the girl you want to be, with me as your guide. Speaking of, let's get started. Can you lie on your stomach, with your head looking up at me?"

"Of course! I will right away!" Coco obeyed her girlfriend and laid down on the bed, looking up as Rarity grabbed a gold watch with an engraved flower.

"Okay Coco, to start I have to make you become suggestible and hypnotized. I want you to focus on this watch. Do you see the pretty, golden flower on it? If you like, you can focus on that as you watch the watch go back and forth. Understand?"

Coco nodded, altering her position slightly, resting her arms on the pillow at the end of the bed and placing her head on them.

"Good girl. Now, I need you to relax, and breath in and out deeply as you watch." Rarity began dangling the watch, back and forth as Coco stared and started her deep breathing.

"Now Coco, once I see that you have become sufficiently relaxed, I will begin to count down from 10. With each number, you will become more relaxed and obedient."

Rarity stopped talking for a moment, watching Coco become more and more focused on the golden pendulum, and began to count.

"10... you are becoming more and more relaxed and you are losing awareness of your surroundings."

"9... more and more sleepy..."

"8... you feel immensely relaxed and submissive to me. You fully trust me with your mind."

"7... feel your body melting away as you entirely focus on the watch.

"6... Keep going darling, you are doing so well. All the feelings I am describing are no becoming more and more intense, and your inhibitions are melting away as well. Feel your thoughts and resistance going away, rolling out of your mind and into the ground like rain.

"5... even stronger now. You are now half asleep, and becoming more and more controlled and suggestible."

"4... You're doing so well darling. We are almost done, and you're almost completely under my control."

"3... you are now fully asleep, the parts of your mind that are still active will entirely listen to my voice and obey everything I say."

"2... Almost done, just a little more~"

"1... you are now fully under my control. You will believe everything I tell you, and it will all become true to you as soon as it's said. When I ask you if you understand, just say 'Yes, Mistress.' Do you understand, Coco darling?"

Coco, eyes closed, nodded. "Yes, Mistress."

"Good girl. First, I am going to make you forget all of your memories of being a boy. After this session, you will not remember any sensations of male puberty, growing up as a male, or even your penis that we call your clit. Do you understand and obey?"

"Yes, Mistress Rarity."

"Good Coco. Next, I am going to create memories of you growing up wearing dresses, playing with other girls, and just being a young girl all the way until you became an adult, and transitioned. Do you understand?"

"Yes, Mistress." Coco felt a rush of thoughts come into her head, years of memories being inserted all at once of her having a typical female childhood, the pretty clothes she would wear, and even her memory of meeting her love Rarity changed from her being a feminine 17 year old boy to a fully-female 17 year old young woman.

"You're such a good girl, darling. Now, we are going to alter your memories of that penis I talked about before. I know you already refrain from ever using it, but from now on you will never touch it again, even to use the bathroom. You will continue to sit down to urinate, and when you orgasm from sex or masturbation just allow your fluids to drip from it without any involvement from the little organ itself. Lastly, you will continue with calling it a clit or clitty when you must mention it. Do you understand, Coco?

"Yes Mistress, I will never think about or use my penis ever again, and it shall remain as my clit as you instructed."

"Good girl. Finally, when you awaken, you will put on this chastity cage, and wear it during sex and during the day from now on. This will reinforce your femininity, and make you feel good and safe. Do you understand this?"

"Yes Mistress."

"That's a good girl. Now I want you to wake up from this trance and tell me how you feel."

Coco opened her eyes, yawning and looking around. She felt different than she remembered, more content and obedient than she ever had before. "Wow, I feel really good Rarity, thank you!"

"Darling, I love you. I hope you know that."

"I love you too Rara. Oh, excuse me, I need to put on my cage."
