Some interesting potion[NSFW]

Rainbow wondered what Twilight could have possibly meant by that
 
Uuuhh, no… not really why?
 
Rainbow said with a puzzled look on her face

Twilight then asked again
 
Are you sure… You really never wanted to do magic at all?

Rainbow answered
 
No…. Not at all
 
Rainbow had little to no idea about how to use magic, let alone practice it

Twilight sigh and just drop her arms down
 
Well forget it I guess…
 
She then started to walk away toward the library, she remembered she took some book from the old castle and bring them here

Rainbow remembered that Twilight had a surprise for her
 
Wait Twilight! Maybe I DID have a little interest in magic at some point in my life, but why do you ask?

Twilight tugged on their tail as she keep walking
 
I just want to know if you are interested in magic, I don’t care if you can or cannot use it…
 
She said explaining her as she walk

Rainbow had a struggle speaking as her tail was being pulled
 
I… Ugh… have had a….Ugh.. little bit of interest..UGH, yes.

Twilight keep walking and just tug quick on their tail to bring her back
 
Just keep up instead of standing there… And I want you to be 100% sure that you have interest in magic

Rainbow’s butt started to hurt from all the tugging
 
YES! I love magic! Now, what’s the surprise! Tell me, Twi!

Twilight smiled and stopped. She kiss her on the cheek and let go their tail
 
Well then close your eyes and you will have your surprise
 
She said happily hugging her

Rainbow closed her eyes and opened her hands
 
OK, I’m ready. Lay it on me She said with a big smile

Twilight smile as she hugs her and she made her horn glow. Her magic was going further then simple spell and had a much bigger aura. When she finished her spell, they were in a sort of foggy blue place, floating in the air
 
Its almost done
 
Then Rainbow’s inner magic come out of her and surround her. Everything went really bright and once they were back in the castle. Rainbow Dash had a horn
 
You can open your eyes now
 
She told her, the angle was letting Rainbow see the tips of it at the top of her vision

Rainbow looked down at her hands and wondered what just happened
 
Wh… wheres my gift?
 
She began looking around until eventually, she saw the pips of her new horn
 
HOLY SHIT! NOT ANOTHER ONE OF YOUR SURPRISES!
 
She began feeling her horn

Twilight then said smiling and kissing her
 
Relax. Rainbow, I just made you an Alicorn, its nothing bad.
 
She said smiling
 
This is my gift.
 
She giggles as Rainbow was feeling her horn since it was new to her

Shit, dude! You can’t just spring this on someone! But I appreciate the sentiment.
 
Rainbow continued to feel the new horn

Twilight giggles and kiss her
 
Well I asked you if you were interested in Magic and you told me that you were, so I have my answer and could give you my gift
 
She kiss her again then said
 
Don’t touch it too much, you will go blind
 
She said with a giggle

Rainbow quickly stopped fondling her new horn
 
BLIND!? Holy shit! I thought you gave me a horn, not a weapon!

Twilight started laughing really loud
 
Whaaahahahahat?!!!
 
She cracked up and fell to the floor laughing uncontrollably

Rainbow had a struggle standing up when Twilight fell down laughing
 
Oh ha ha! Very funny! I’m sure you freaked out when you first found out how powerful your magic was!

Their tail was long enough to let Twilight be on the floor an Rainbow be standing up. She just keep laughing
 
No… Not really.
 
She calmed down a bit
 
I was born a Unicorn, I’m used to magic but yes when I got my cutie mark it did went all powerful… But i didn’t really freaked out
 
She explained getting back up

Rainbow rolled her eyes
 
Whatever, let’s just go in there and find your book.

Twilight smile and just start walking again toward the library
 
Anyway, how does it feel to be an Alicorn Dash?
 
She asked smiling

Rainbow was still looking up at her horn as she was walking
 
Uh… weird. Very, very weird!

Twilight smiled at her and give her a kiss
 
You’ll get used to it. You should also start feeling your magic raising up slowly and all that. I’ll teach you the base of magic and levitation so you don’t have to worry about that.
 
They keep walking and eventually reach the library

Rainbow caressed the spot on her cheek where Twilight kissed her
 
Gee, thanks, Twi. I’m sure I’ll learn a lot from you. Levitation can be quite useful after all.
 
Rainbow looked up at the ceiling when they entered the library
