#1 of Rainbow Road (MLP)

Twilight develops a new spell to help Rainbow Dash fly better. The spell however, has unexpected side effects.


"Alright I think my new spell is ready" Twilight Sparkle gleefully says, wings fluttering in excitement. "That's cool and all Twi, but why do I have to be here" Rainbow Dash questions while rolling her wings "My wings need stretching, besides I'm not cut out for this kind of egghead work" The rainbow pegasus snarky remarks. "Oh Rainbow I think you'll like this. This spell should increase your muscle density, allowing you to fly much faster and longer" The alicorn aloofly says "Now Rain" Twilight starts before Rainbow Dash cut's her off "Then what are you waiting for hurry up and cast it on me, lets see what this spell can do" Rainbow Dash says suddenly excited at the prospect "But the spell" Twilight tries to say before once again getting cut off by Rainbow Dash "Yea yea I know the spell's untested and blah blah blah, only one way to test it now hurry up" Rainbow Dash urges "Ugh" Twilight sighs in resignation "Fine brace yourself" Twilight tells Rainbow as magic gathers around her horn. A brilliant flash floods the room, fantastic colours light up and fade in a majestic form before dissipating.

"I feel amazing" Rainbow exclaims, jumping up and starting to fly "Ugh Oh~h" she moans as she tries to fly. She's much stronger at least on par with Applejack and she knew it, but she felt an incredible pleasure wash over her. Emanating from between her hind legs "Oh~ Twi I feel, Ugn~n so good, what's wrong" Rainbow moans out, her voice pouring out as honey. "Well Rainbow you got a few new additions. That equipment would make Big Mac jealous" Twilight tells her behind muffled laughs "What do you mean Twi" Rainbow dash says panicked "Here look" Twilight says magically pulling a full length mirror "Why do I need" Rainbow Dash starts "WHY DO I HAVE A DICK AND BALLS" She finishes in complete surprise "Well Rainbow it must be a side effect of the spell. While it made all your muscles more dense it must have given you male characteristics" Twilight says looking at Rainbow Dash's new cock. Her new cock was had a very impressive size, both length and girth would be enough to ravage the depths of Celestia; and her balls they must have been at least the size of large apples. They were certainly potent Twilight could easily see that for the thick pre-cum dripping from her twitching cock.

"So what you're saying is you're to blame then" Rainbow Dash says as her legs shake "The spell did it but if you" Twilight starts "Then you'll help me with this" Rainbow Dash interrupts as she mounts Twilight "RAINBOW WHAT ARE YOU DOING" Twilight yelps in surprise "What do you think, this princess is about to be broken in" Rainbow says as she powerfully thrusts her new cock deep into Twilights wet, waiting pussy. Rainbow unused to the feel of a having a cock blasts her load into Twilights fertile waiting womb "R-Rainbow did you" Twilight quiveringly moans "Hey I'm use to a pussy, not a cock besides" Rainbow coos as she rests her head beside Twilight's "I'll last longer now" she moans as she nuzzles her muzzle against Twilight's "Ugh I was going to tell you not to cum inside but it's too late for that" Twilight wistfully says "But I can think of worst ponies to have foals with" Twilight says more upbeat as she feels Rainbow's cock twitching inside her "Wait foals can't you use magic to not get knocked up" Rainbow Dash says in utter disbelieve "I can't, not for this sperm. It was made with supremely strong magic and many spells on top of each other, even if I knew how to unravel the spell I couldn't bring forth the power to neutralize the sperm" Twilight says matter-of-factually "Oh well um, s-sorry Twilight" Rainbow embarrassedly says "It's too late now Rainbow, now you came and I didn't so start thrusting Dash" Twilight commands the pegasus "Right away Twi" Rainbow eagerly says, her cock twitching.

As Rainbow Dash starts thrusting she fully feels the inner embrace of Twilight's pussy, while tight in was warm and welcoming, with each fold caressing and massaging every last part of Rainbow's cock. As Rainbow got use to her cock she tried making it twitch inside her pussy in rhythm with the contractions of her breeding mate. "Oh yes Dashie, that, do that more" Twilight moans as Rainbow's cock twitches in perfect rhythm with Twilight's pussy "Twi, I wanna go deeper but I can't. It get's too tight when I try" Rainbow moans as her cock slams into a spongy wall "Ah~n" Twilight moans in a honied mixture of pain and pleasure "That's my cervix Dashie" Twilight starts "Wait there's more" Twilight cuts herself off in utter surprise "Not much more but yea there is" Rainbow dash moans hardly, her cock ravaging Twilight's pussy. As Rainbow starts to pull out her cock she powerfully slams it back in as soon as the head touches her outer lips "Ugh~n oh~h Dashie" Twilight moans as Rainbow's cock batters Twilight's inner most wall. Twilight's front legs crumple, slowly lowering her to rest on her breasts and chest letting Rainbow slam her cock in stronger "Oh yea Twi now this is more like it" Rainbow moans as she speeds up her thrusting "Ugh yea gonna cum" Rainbow moans "Hi Twilight I'm here for, oh my" Fluttershy starts to quietly say as she opens the door, only to be greeted to the sight of Rainbow Dash and Twilight Sparkle mating "Me too Dashie" Twilight moans out. The two ponies orgasm in unison, Rainbow powerfully blasting more of her potent sperm right into Twilights baby room. The two ponies laying together in post orgasmic bliss. Only during the bliss do they see a shocked Fluttershy standing in the doorway "I'll um, I'll come back later" Fluttershy stammers as she quickly leaves.
