Some interesting potion[NSFW]

Rainbow smiled when Twilight gave her a peck on the cheek. Suddenly, she had an idea on how to make Twilight feel better
 
Hey, Twilight, do you know how to do the “futa” spell?
 
Rainbow asked with curiosity, hoping she would say yes

Twilight was a bit confused now at her question. What futa spell?
 
Hum… what do you mean?
 
She asked her in hope to understand. they were still on the couch. Rainbow over Twilight and their breast squished together

Rainbow tried to describe the spell carefully, as she didn’t want to scare Twilight away from the idea
 
Well… heh heh, uh… the futa spell will grant any mare a fully working penis for a short period of time, usually no more than 30 minutes, or so I’ve read in one of your spell books. What I’m saying is, give yourself a cock, and I’ll make you feel extreme pleasure.

Twilight kinda rise an eyebrow at her and then said as her idea was a bit stupid
 
Hum… I already have a penis at the moment… Even if I knew such spell… I wouldn’t use it on myself, I like being the girl… And Also it wouldn’t do anything because like I said, at the moment I do already have a penis…

Actually Twilight, we have a CONJOINED penis. Not as much fun as a single penis. Also, you could still be the girl in this, and I’ll be the one on top.
 
This way we’ll be free and we could still enjoy ramming each other.

Twilight then face palm and then said
 
There is a little problem in your plan, I cannot unjoin us and bring me back to be a mare and I don’t know any futa or gender altering spell… I don’t even know how this here happened!!
 
She said pointing at their joined penis which was still creeping her out

Rainbow looked at Twilight with disbelief
 
So what, you wanna live like this forever, we can’t be seen in public like this! We’ll be outcasts! This whole thing started because I stole a potion from Zecora, surly SHE could help us! THINK TWILIGHT!
 
Panic filled Rainbow’s heart

Twilight then said still not knowing how to fix this
 
No I don’t want but I don’t see any solution!! The only spell I knew that could free us did nothing and Zecora makes potion and potion can’t alter a body that much. Its just chemical. Its why its temporary…

By this point, sex was FAR gone from Rainbows mind
 
Well, then what do YOU suggest we do, sneak over to your house and find your big spell book? Cuz we can’t just SIT here!

Twilight then flails her arms up as she still knew nothing of how to fix this
 
I have no idea!! I read all these books twice and I have nothing!! I wish I could just separate us but I have no idea how!! Magic isn’t that easy you know!!

Suddenly,Rainbow gets an idea
 
WAIT! What were you thinking about last night, just before this happened?  
Before your horn blew out a magic shot that fused us together. WHAT WERE YOU THINKING OF!?  
She begins shaking Twilight

Twilight was now shaken the crap out off while Rainbow was asking her a question
 
I-i-i-i do-o-on-on’t kn-o-o-o-o-w
 
She was still being shaken and didn’t remember at all what she was thinking at that moment. She didn’t even noticed when her horn blasted spells. She didn’t even knew when the fusion happened

Maybe if you thought about us with vagina’s again, it could help. Try ANYTHING. Begged Rainbow

Twilight then simply said
 
Magic doesn’t work like that Dash, its complicated, its not just, think of something and it happen. It have script that you read that define what magic does and there is also many other factor. I cannot just wish us to have your vagina back to have it to happen… I’m sorry…
 
She sigh and look to the side. She was sad that it was how ti works too since she also wished to have her vagina back
 
If it can comfort you… I’m happy that it happened with you
 
She said with a smile

Rainbow was in fact comforted by this. Her ears went down and she smiled
 
Y’know, it does actually make me feel a little better, thanks twi.

Twilight smiled happily and then said leaning to her ear
 
If it didn’t happened, I would have found a way to do it to us anyway. I’ll be more then happy to pass the rest of my life with you.
 
She kiss her now on the lips and dive her tongue in Rainbow’s mouth

*As Twilight was eating out Rainbows mouth, a thought dwelled on her. After all this, all the complaining, the pain and the torment, Twilight still loved Dash.
 
How could I have treated her so meanly? Rainbow thought She’s smart, sexy, funny, and really forgiving! I’d be a fool to let her go!

You know, Twilight, even if you did find a way to free us, I’d still be attached to you by the hip. With the attachment of love. Hell, I might just MARRY you, kid.

((How does she speak while kissing?))

You know, Twilight, even if you did find a way to free us, I’d still be attached to you by the hip. With the attachment of love. Hell, I might just MARRY you, kid. Rainbow Dash thought to herself while tasting Twilight’s hot breath in her throat

((Now that makes more sense but maybe next time using italic for thought :v? I’ll do that actually))
 
Twilight keep kissing her lovingly, she really fell in love with Rainbow Now. She kiss her for a moment now, making their tongue dance
 
Maybe you don’t see how we can live like this but if you ask me, I really don’t mind. It starting to grow on me
 
She said happily and wiggling her crotch which tugged side to side on their shared penis and it turned her on

The wiggling began to turn on Rainbow Dash as well
 
TWILIGHT! She said stopping the kiss
 
I just wanna let you know that I’m OK with this too. As long as I’m with you, I’m happy She gives a quick kiss to Twilight on the nose
 
But, there is just one thing, how are we gonna explain this to our friends? We can’t just stay in here forever.

Twilight didn’t know how they would explain this to their friends at all but she decided to keep teasing her by wiggling her butt around which forced Rainbow Dash to follow her movement since it was tugging on their penis
 
I don’t know how we will explain them…
 
She sigh as she didn’t wanted to think about it too much

I know you don’t wanna think about it too much, but we need to get his out of the way. Better now than later.
 
I’d hate for our love to separate us from our friends, but how would you explain conjoined dicks to them?
