Corrupted Twilight x Rainbow Dash [short greentext]

>Rainbow Dash turns to the sound of hooves clopping up toward the tree she's resting in, finding Twilight Sparkle with a smile on her face

>"Oh, hey, Twi!" Rainbow hollers, and hops down from the tree to greet her

>"Hello, Rainbow Dash."

>Rainbow raises an eyebrow in response to Twilight's rather stoic greeting

>She shurgs it off as another 'Twilight' thing

>"So," asks Twilight, "how has your nap been?"

>"Fine..."

>Twilight's grin grows to odd proportions, and Rainbow now notices her hair is a bit frazzled

>It's possible she's tardy on a report again and she's come to Rainbow for help

>She didn't have to do it with that creepy smile, though

>"Are you okay, Twi? You look a little out of it."

>"Oh, sorry about my appearance..."

>Her gaze turns darker

>"I've just been practicing a little dark magic. Really takes a toll on the mind."

>Rainbow gives and uneasy laugh

>"Uh, yeah, sure. You should try a nap. Like I'm going to do. Away from here."

>Turning around, Rainbow lowers her haunches in preparation for liftoff...

>...but yelps in surprise when a foreign object is shoved into her marehood

>She spins her head toward her rear, finding Twilight horn-deep in her sex

>"Twilight, what the heck are you doing?!"

>"I'm going to make you feel good Rainbow. Don't you want to cum?"

>"No! What in Equestria has gotten into you?"

>Rainbow tries moving forward to dislodge herself, but Twilight pushes aggressively forward every time Rainbow attempts to escape

 

>No more messing around

>Rainbow doesn't have the leverage to buck Twilight off, but she's a lot faster

>Tensing her leg muscles, she readies for a surge forward

>"Rainbow, I really think you should stick around."

>"Screw you, Twilight!" With that, Rainbow launches herself forward

>Or would, if she was still in control of her movements

>However, a familiar purple glow is surrounding Rainbow, freezing her limbs

>"Stop it, Twilight! I don't want this!"

>Twilight huffs

>"I haven't even started yet! How can you know you don't want it?"

>"You're my friend Twilight, not my lover. I don't want it like this."

>Rainbow hears Twilight lick her lips rather loudly

>"Mmmm. Lovers, you say? I like that idea. But let me show you what I can do first."

>Twilight's eyes light up, glowing green and emitting an eerie purple mist

>Sweat is dripping from Rainbow's forehead and she starts to really panic

>She opens her mouth to yell for help, but finds it instantly filled with a ball gag, materializing out of the air and securing itself around her head

>"I'd hate for somepony to interrupt us before you got to feel good. Don't lie and tell me you don't enjoy feeling good."

>Twilight starts retreating her horn from Rainbow's sactum, slowly letting the grooves stimulate every inch of her inner walls

 

>Rainbow mumbles into the gag, attempting to rebuke Twilight, but she takes it as encouragement

>"Why didn't you tell me you were so eager? We could have cut all the chit-chat and gotten right to it!"

>As soon as her horn is almost all the way out of Rainbow, Twilight shoves it back in

>Then again slowly pulls it out

>After the fourth thrust, Rainbow can't help but moan into her gag

>Her body betrayed her as her marehood began to wink

>"See, I knew you wanted it, Rainbow. You body can't lie to me."

>Rainbow heard a chime behind her as Twilight casted another spell

>"But you're so loose in here. You must have pleasured a lot of stallions."

>A low growl comes from behind the gag

>"Mares? Oh that makes this so much better, Rainbow!"

>The horn is thrust back into Rainbow, but this time, it's much longer and wider

>The pleasure rips through Rainbow's body like a thunderclap

>"Now, let me show you what I can do."

>Rainbow's eyes widen in fear, and she renews her stuggles, but Twilight's magic holds her fast

>Slowly, painfully slowly, the horn begins to spin

>Once Rainbow feels the shifting in her nethers, she cries out, drooling into the gag

>"I'm excited too, Rainbow. But if you struggle..."

>Twilight's voice deepens

>"...you'll just make me hotter."

 

>Her horn spins faster now, thoroughly lubed by Rainbow's arousal

>The faster it spins, the more intense Rainbow's pleasure becomes

>She moans almost constantly into the gag, her tongue limp and lolling out of her mouth

>Unconsciously, she raises her tail as well, giving Twilight easier access to her treasure

>Twilight notices immediately

>"I knew you'd come around, Rainbow."

>While her horn pleasures the pegasus, Twilight moves a hoof to her own nethers, stimulating her now wet marehood

>Now finding its perfect speed, her horn sends waves of ectasy through both Rainbow and Twilight

>Twilight presses her hoof as hard as she can into her own flower, sensually rubbing it back and forth

>Rainbow feels herself coming closer and closer to orgasm, the spinning horn driving her sensitivity to places she'd never even imagined

>Before she's sent over the edge, however, Twilight withdraws

>"I've been good to you, Rainbow. Now you be good to me."

>Rainbow finds herself face-to-face with Twilight

>"Now if you play nice, I'll let you cum. I may even let you go."

>Twilight's smile turns darker

>"But if you disappoint me, or try to call for help, you'll be BEGGING for release a WEEK from now."

>Rainbow nods emphatically, desperate to feel that pleasure again, that incredible peak Twilight had nearly taken her to

>Twilight positions her sex next to Rainbow's mouth, and the ball gag vanishes

>Instantly, Rainbow is on Twilight, thrusting her tongue inside Twilight's tunnel as far as she can

>"You're almost as enthusiastic as me!"

>Ignoring the statement, Rainbow continues to explore Twilight, curling and writhing her tongue, elliciting short moans from the unicorn

>"Oh, there's no way I can't reward this."

>She dives into Rainbow much like the pegasus dove into her

 

>The two vy for control, attempting to pleasure the other into submission

>Rainbow feels her tongue snagged by Twilight's magic, then gapes in awe as it grows

>It gets longer and longer, and eventually Rainbow can reach all the way to Twilight's cervix

>The tongue continues to expand to the point that Twilight's entire passage is filled

>All Rainbow can do is shift her tongue

>Any sort of movement stimulates all of Twilight's sex at once

>Rainbow feels the upper hand, as Twilight's own tongue has slowed and her moans have become louder

>She quickens her movements, and Twilight's walls clamp down on her tongue

>Between her own saliva and Twilight's juices, though, she still has enough lubrication to move around

>So she thrusts mercilessly, and is soon rewarded with a squeal from Twilight

>The unicorn's entire body tenses, wracked by orgasm as her cum flows freely down Rainbow's tongue and onto her face

>Rainbow uses her enlarged tongue as long as she can, though it soon shrinks back to its normal size

>Surprisingly, Rainbow finds herself disappointed

>"I knew you just needed a little encouragement."

>Twilight shifts, moving her face back to Rainbow's and rubs their marehoods together

>A sultry look in her eyes, she joins her mouth to Rainbow's in a deep kiss

>Their tongues enertwine and dance with the same intensity they had just shown in the others' sexes

>After holding the kiss for a while, Twilight breaks away

>"Now, Rainbow, I've found a very special spell. One only possible with dark magic. I've only tried it on myself, but I can tell you it works wonders. Do you want to see it?"

 

>Rainbow nods, eager to let Twilight make her feel good again

>"It's find the pleasure centers of a mare's body and triggers them all at once, ensuring an instant and total orgasm. You want to cum, don't you? Earlier you said you didn't..."

>Again, all Rainbow can do is nod

>"Silly me, of course you do," says Twilight.

>With that, her horn glows a dark purple, a much more cruel color than Rainbow is used to, but she no longer cares

>A glow of the same color washes over Rainbow, collecting on certain parts of her body, mostly near her sex

>"Now cum!"

>The spell ignites, roaring over Rainbow with an impossible level of pleasure, sending her mind blank and her body into an instant orgasm

>Cum drips out of her marehood and onto Twilight's, which is still grinding against Rainbow's

>Rainbow begins to pant, trying to hold eye contant with Twilight, her savior

>"Cum again!"

>The spell rips through Rainbow a second time, forcing a shriek from her mouth as she throws her head back from the stimulation

>She slowly lowers her head again, her eyes glazed over and barely open, begging for Twilight to continue

>"Oh, Rainbow, who knew you had such a dirty-looking love face. But I need you to do me a favor."

>Rainbow leans in, offering Twilight an ear

>She whispers into it

>"Cum again."

>Once more, Rainbow is overwhelmed by ecstacy, tearing through every inch of her body, releasing more and more cum onto Twilight

>She's gasping for breath now and collapses onto the ground

>Soon after, she loses consciousness, the last thing she sees being Twilight's dark smile and green-glowing eyes

 

>Some time later, Rainbow can't tell how long, she wakes up

>The room she finds herself in is dimly-lit, with the only light of any strength bearing down on the pegasus

>She attempts to stand up, but finds all of her legs secured to a table

>Mumbling through drowziness, she squirms, attempting to free herself

>Whatever noise she made must have been enough to alert her captor, as a door swings open, letting more light into the room

>Rainbow recognizes the area as Twilight's basement, which means her captor must be...

>"I'm so glad you're back awake, Rainbow! I couldn't wait to play with you again."

>Now that Twilight wasn't thrusting into her, Rainbow's head felt much more clear

>And she was very pissed

>"Oh, screw off, Twilight! Let me out of here!"

>Twilight clicked her tongue and shook her head

>"I was hoping our escapade earlier today had brought you around, but I see you will require more work. That's what this is for!"

>A puff of corrupted purple magic summoned a belt around Rainbow's flank, holding a horn-shaped object at the entrance to her marehood

>With another flash of magic the horn thrusts mechanically inside of Rainbow, then out, then back inside

>The force was enough to shove Rainbow's entire body forward

>"I'll just leave you with that for a few days. I suggest you don't fight the pleasure, it will only make your time down here more difficult."

>"Damnit, Twilight, I'll never forgive you!"

>"Actually, Rainbow," says Twilight as she walks out the door, "I think you'll never be able to thank me enough."

>The door slams shut, leaving Rainbow with the horn diving in and out of her, already working her body to its first orgasm

>She screams
