It was a dark evening in Ponyville, approximately two hours since nightfall. Rainbow “Danger” Dash is lurking in the darkness. Her goal was simple; recreate the experience she had with Twilight and Spitfire at Cloudsdale that doesn’t involve drinking…and Spitfire much to the blue pegasus’s dismay.

For the past two weeks Rainbow Dash has been plagued by perverted thoughts about her brainy friend, they were around since the day she and Spitfire took turns riding or get mounted by Twilight, but they became much more powerful when Pinkie wanted to talk to her about Twilight.

The problem with this was that Pinkie didn’t just talk about the egghead, but also  how nice it is to be filled by her cock or to taste the purple monster’s seed. Rainbow Dash wouldn’t mind it too much if Pinkie didn’t explain it all in great detail, down to the actual flavour of Twilight’s cum…which is a combination of raspberries and grapes with a slight drizzle of salt.

Ever since that day, Rainbow Dash can’t look at raspberries or grapes the same way if there’s a salt shaker near them. But that wasn’t the problem; the REAL problem with Pinkie’s chats was that Rainbow Dash hung on every word that Pinkie described. The cyan mare would be six feet underground before she admitted that she loved listening to how Twilight took Pinkie to town in bed.

The downside that made apparent quickly was that Rainbow Dash had to postpone her training or her napping just to clop to the images Pinkie instilled into her skull. After a week since she and Pinkie started having their “Twi-Fuck-Buddy” chats, the blue pegasus’s mind began to alter the scenes that would play in her head. Instead of Pinkie getting mounted, it would be Rainbow Dash.

She would be positioned with her front hooves on the bed, back hooves on the floor, shaking her rump to entice the purple shaft. She would be bouncing on the purple unicorn’s crotch, thoroughly enjoying the feeling of the librarian’s cock filling her. The straw that broke the pony’s back was while she was napping, the blue pegasus was lying in Twilight’s bed wearing dark blue lingerie; panties, socks, a collar, and a saddle.

The very moment the dream when Twilight pounced on her, cock erect, was the moment Rainbow Dash awoke in a sweat. And that was that, Rainbow Dash thought out a quick plan to get Twilight to screw her, her biggest problem being Pinkie. Daring was in Canterlot doing museum stuff, Lyra hasn’t left the Candy store all day, and anypony else Twilight had fucked before aren’t currently in Ponyville at the moment.

So she had to incapacitate Pinkie Pie first.

She found her target strolling to the Library, and she leaped into action. “Hey, Pinkie.” Rainbow Dash said.

“Oh hi Dashie, whatcha doing?” Pinkie asked, rather curious about why the blue mare isn’t napping in a cloud or at home.

“I actually wanna ask you something,” Rainbow Dash muttered, nervous as to how she was going to word this to her best friend.

“Oh you wanna have fun with Twilight, right? Okie Dokie Lokie, I’ll leave Twilight alone tonight for my bestest friend,” Pinkie exclaimed happily.

“Uh, thanks Pinkie, how did you know?” Rainbow asked, confused.

“Duh, I can smell you AND I’ve been talking to you about Twilight because I think you needed another night with her. Anyways, see ya later,” Pinkie answered in a sing-song voice, bouncing back to the Bakery.

‘Step one complete… I guess’ Rainbow thought as she went to the library. She made sure nopony saw her enter the treehouse. But her cover was blown the moment she saw the purple dragon staring at her, drawing on a piece of paper.

“Rainbow Dash, whatcha doing out so late… in the library?” Spike asked, baffled by the cool pegasus who was supposed to be napping or doing tricks away from a lame place like this.

“Well, I heard Twilight had the all the Daring Do books so I’d thought I’d ask her to let me borrow them,” Rainbow Dash lied.

“You read them all, twice,” Spike replied. While it took a minute he added it all up in his head and groaned. “I’ll go get my basket, stupid ponies that want me to move so Twilight can do them, I hope Rarity doesn’t end up like you and Pinkie, crazy mares.”

She sighed in relief as Spike climbed the stairs; she closely followed the dragon to see if Twilight was up. She may be an overall awesome pony, but it’s lame to make a move on a sleeping mare. She glanced up to see Twilight reading some book that made the speedster’s head spin just looking at it.

“Rainbow Dash, what a surprise. What brings you here?” Twilight asked, her expression changed from happily surprised to suspicion as she saw Spike take his basket down stairs. “Please tell this isn’t about…”

“I’m sorry Twi, I’ve been chatting with Pinkie lately-“

“Stop, I think I can piece it together from there,” Twilight interrupted. “But why exactly? Other than Pinkie talking to you…about me.”

“Well, I figured since we did it once; maybe we can do it again? Help a friend out, so to speak,” Rainbow Dash muttered, giving the unicorn a cheesy smile.

Twilight was not amused. “Look I’m flattered, but I am far behind my studies thanks to Pinkie, okay?”

The plan wasn’t looking too good, so she had no other alternative. “One moment, I’ll be right back,” Rainbow Dash said, flying out through the window.

“She could have used the door like a normal pony,” Twilight grumbled, returning to her reading.

A few moments later, Rainbow Dash returned through the window, wearing Pinkie’s lingerie, a red collar with a heart dangling around the throat, four red socks that had a heart pattern on it, a slim red saddle, and red panties. She was blushing madly on the fact that she was wearing it at all. “Here, does this help?” Rainbow muttered, trying to not look Twilight in the eyes.

It was Twilight’s turn to blush, turning her head away from the blue mare. “Look… you don’t need outfits…like that, to seduce me. I’m just not in the mood, okay?” she stuttered, slowly turning her head back to catch glimpses of the garment clad pegasus.

“So I put all this on for nothing?” she groaned, she began to take the ridiculous get up off, starting with the socks.

Twilight’s mind seemed to slow down as out form the corner of her eye, saw Rainbow Dash slowly take the sock off her fore-limb with her teeth. Her heart pumped rapidly as the blue mare began to take the socks off her hind-legs, noticing that her speedy friend was annoyed by the how to take them off, she could have sworn that there was sweat glistening on her blue fur.

Rainbow sat on the ground and lifted her hind leg up high, and tilted it so she can get her teeth around the hem of the sock, unknowingly shown Twilight her moist pussy. “Stupid socks, who thought socks were sexy, anyways?”

“A trend that came up a few hundred years ago, I think a painter started it by painting brothel mares in socks,” Twilight answered, her hoof failed to cover her right eye, allowing her to see Rainbow Dash take the final sock off.

Rainbow Dash fumbled with the saddle straps with her hooves and found she couldn’t quite reach with her teeth and groaned in annoyance. “Hey Twi, could you get this thing off me, Pinkie put it on me and I can’t reach the straps,” Rainbow asked.

“Oh uh…sure,” Twilight uttered, her horn glowed as the saddle was undone and was lifted off the pegasus.

Twilight’s eyes went wide when Dash went for the panties, the pegasus was clearly too annoyed to care but she fell on her belly as she did so, her flank raised towards the unicorn as her fore-hooves pushed the fabric down. Once again, Twilight’s brain slowed time for her, letting her watch the thin piece of cloth slide across her cutie marks, and ultimately revealing Rainbow Dash’s marehood, still moist from the earlier embarrassment.

Rainbow kicked the dumb fabric away as she got back up, no longer giving the unicorn a show. She struggled with the collar, “Hey Rainbow, come up here. Collars can be pretty tricky, I’ll help you get it off,” Twilight spouted, surprising both ponies.

“Uhh, sure. Pinkie did say I can’t take this thing off without help, but can’t you just magic it off like you did the saddle?” Rainbow asked.

“A collar is smaller and requires precision otherwise I may strangle you by accident,” Twilight quipped. The speedster shrugged and flew up to meet the unicorn, who was sitting flat on the bed.

Rainbow Dash sat down next to the bed while Twilight studied the collar. The unicorn didn’t really pay any mind to the collar itself, she just stared at how the collar itself fit on Rainbow’s neck. “You know…the collar… suits you, I think,” Twilight muttered, her magic barely touching the leather strap itself.

“No way, I hate this thing, it itches and it’s uncomfortable. Just take it off,” Rainbow whined.

“Well, this is Pinkie’s after all. Maybe we can find you a collar that would be more ‘you’? Twilight said, quickly clamping her mouth shut with her hooves.

“Again, Twi. I don’t like…Hold on,” Rainbow Dash muttered, adding all the pieces together, turning slowly, preparing her teasing face. “You like me wearing this collar, don’t ya?”

“Of course not, it’s just a bit of fabric and fake leather. I was thinking more about what you would like, you never know until you try, right?” Twilight explained, talking herself into a corner.

“I know you couldn’t resist Rainbow Dash for long,” the blue pegasus gloated, crawling onto the bed.

“Well, you got me alone in bed. I guess you would want to lead?”  Twilight asked, sitting on her rump, her purple dick standing at attention.

“Well, actually,” Rainbow Dash muttered, “I heard about how you started to dominate Pinkie and was wondering…”

“You want me to lead then?” Twilight said, rather shocked that the speedster would rather be on the bottom. Rainbow nodded and smiled sheepishly as Twilight shuffled herself back, sitting against the headboards. “Alright then, let me think. I know, get me ready for you.”

“Uhh, okay,” Rainbow replied, moving forward, her face getting closer to Twilight’s shaft. She was confused with where to start on this monster, as her memories of that night in Cloudsdale were fuzzy.

“You can start by stroking the rod with your hooves while you lick the head, or you can lick along the length, “ Twilight tipped.

Rainbow nodded, deciding to take the first option. Her hooves pressed against the sides of the dick while she opened her mouth near the head. Tentatively, she slowly placed her tongue on the edge of the flared tip, letting herself get use to the taste. ‘A little salty, but I kinda taste the raspberries. But in all seriousness, how did I do this before? she asked herself; her tongue moving slowly around Twilight’s penis.

Twilight let out a soft moan, letting the blue pegasus feel it out for herself. She ran her hoof through the rainbow mane, petting the pegasus, the action made Rainbow Dash’s face turn red completely while also causing her hooves to work the shaft faster, making Twilight feel rather good. “If you want, you can try and take me into your mouth. Just don’t take too much, let your hooves massage what you can’t get in,” Twilight added, still petting the pegasus.

Rainbow Dash took a deep breath before opening her mouth to take what she could, slowly feeding the cock towards the back of her throat. She felt a jolt of pleasure when Twilight moaned; making her feel very good that she is doing a good job at least.

She tried to run her tongue around the sides of it as she backed out of it, she thought that maybe she could just bob her head rapidly around the purple cock. Testing her theory, she did just that, her head attempting to be a blur in the unicorn’s crotch.

Twilight watched in confusion as Rainbow bounced her head on her prick, “Rainbow, stop.”

“What? I thought you’d like it,” she answered, saddened that the unicorn disapproved.

“You gotta lick it more, the way you just bobbed your head like that had no emotion, it looked like you were bored with me,” Twilight stated.

“No I’m not bored, I just thought it would be better, I’ll try again,” the blue mare muttered, returning to her old position. Gently licking the underside while massaging the shaft with her hooves, as she had plenty to work with.

Rainbow tried to take as much of the cock as she could, taking half of it into her mouth. She took it out quickly letting her tongue tease it as she left, she began to pump the length with her mouth, letting her tongue lap at the member, her saliva trailed down Twilight’s cock until reaching the base, caught in the purple fur.

One of Rainbow’s hooves began to tease the unicorn’s marehood while also working her mouth around the needy prick, prodding the lips, slipping a bit of her hoof between the folds, causing Twilight to squeak.

Having difficulties controlling herself, Twilight placed her other hoof on Rainbow’s head and slowly forced more of her cock into the pegasus’s mouth. The action surprised Rainbow, she attempted to lift her head off but was forced down by the enraptured unicorn. Soon the two found a rhythm that Twilight enjoyed, and Rainbow Dash slowly accepted, as pre-cum graced her tongue.

“I’m close, Dash,” Twilight moaned, still using the pegasus’s head.

Upon hearing this, Rainbow recalled that Twilight lets out lots when she cums and struggled to get off, surprised by the strength the unicorn suddenly had.

Twilight let a sigh she came, forcing the spunk to hit the back of Rainbow’s throat. Rather fortunate for the speedster that Twilight’s didn’t try to fully impale her on her cock, but the amount of spunk became too much for her to swallow at once, forcing it up through her nose. She released the cock and began coughing, saliva and cum dripping from her mouth and some of Twilight’s jism trailing from her nostrils.

Twilight shook herself out of her stupor when Dash began coughing. “I’m sorry, Rainbow. It felt really good, and I felt impatient. Are you okay?” she apologized.

“Just... peachy.” Rainbow muttered, wiping some stray strand of cum from her mouth before licking it up. “Pinkie’s right, it does sorta taste like raspberries, grapes with a salty texture.”

Twilight sat there confused by Rainbow Dash’s statement. “So what’s next? You are leading after all,” Rainbow asked, waiting eagerly for the next event.

“Well, you lie back. And I’ll do all the work for a little bit, then you can just do what feels natural at the time, I guess,” Twilight explained. Rainbow nodded, and got comfy on her back as the unicorn strode over between the pegasus’ hind legs, letting her mare-meat rest on the blue mare’s belly.

Rainbow Dash took a deep breath, nervous that Twilight’s cock was going to enter her. “Just take your time; we want this to last right?” she uttered.

“Of course Dashie, I don’t want to hurt you,” she cooed, pressing her lips to the pegasus’. She began prodding Dash’s entrance with her cock, Rainbow’s spittle helping her get the tip inside.

The sudden intrusion caused Rainbow to gasp in pain, making the unicorn stop to let her blue friend get used to her size. The cyan mare opened her eyes and gave Twilight a smile and nodding, letting the purple mare continue.

Twilight sighed in relief that her was okay, but she had to continue. She slowly pushed her needy member deeper into the pegasus, causing her forelimbs to tighten around Twilight’s neck.

Rainbow felt Twilight’s dick fill her, making her gasp and writhe. She looked down to their connection to find that Twilight was nearly hilted inside her, satisfied that she could take all of the purple mare’s meat.

“Are you ready, Dash?” Twilight asked, the pegasus nodded her head. Taking that as her cue, the unicorn took much of her girth out only to shove it back in, forcing a moan from Rainbow Dash. The pegasus’s years of practicing for the Wonderbolts showed well in Twilight’s opinion. The athletic muscles gripped Twilight tightly, flexing and massaging the purple member.

Rainbow buried her head in Twilight’s neck as the purple mare continued to pound into her, moaning into the purple fur, she soon felt Twilight’s own fore-legs wrap around her, holding her as she moved her hips into the pegasus. At that moment the only thing that mattered was Twilight, she felt that if the world could have end at that moment, Twilight would save the day (with Rainbow’s help of course). She nuzzled Twilight deeply, smiling contently, feeling far more pleased then she has ever been in the past.

Twilight noticed the change in Rainbow’ behavior and smiled, stroking her hoof through the rainbow mane as she continued thrusting. The two thoroughly enjoyed their love-making, as if nothing could ruin this moment.

All good things must come to an end as both ponies felt their climaxes coming, Rainbow laid her head back and the two ponies gazed into each other’s eyes, before kissing each other. Their tongues dancing and mingling with each other, as Rainbow’s pussy convulsed around Twilight’s cock, forcing the unicorn to fill the pegasus’ womb.

They broke the kiss and nuzzled each other, lying on the bed as they let sleep take them, Twilight’s cock still pumping sperm into Dash’s slit. The cyan mare had never felt more relaxed or safe in her life.

Rainbow woke up first to the unforgiving sun; she groaned in annoyance as the sunlight nearly blinded her when she had a pleasant reminder, Twilight’s soft member was still lodged in her pussy, a large puddle of fluids can be seen beneath the connection. Rainbow smiled as she recalled last night’s event, brushing Twilight’s mane out of her cute face.

Rainbow got out of bed, grunting in dismay of Twilight’s dick leaving her as she flew downstairs to have breakfast, letting the unicorn rest.

She was greeted by Pinkie, wearing an apron and flipping pancakes. “Hiya Dashie, how was last night, did the underwear work?” she asked.

Rainbow sat down and let out a happy sigh, “it did work, thanks Pinkie,” she uttered, she reached back to find that she was still wearing the collar from last night, blushing madly.

“I take it you enjoyed being Twilight’s pet?” Pinkie giggled, causing the blue mare’s face to heat up.

“No way, I just forgot to take it off. Besides, I rocked Twilight’s world, she was begging me to stop saying ‘oh Rainbow, your pussy is so good, please let me cum inside’, only natural when you’re with me,” she chuckled.

“Funny, I don’t remember us talking too much during that.” Rainbow turned to see Twilight walk in, her member still in sight.

“Well, you were pretty good yourself,” Rainbow uttered, blushing.

“So I’m told. Smells great Pinkie,” Twilight commented, preparing her morning tea.

“Thanks Twily, I’ll be done super quick,” Pinkie replied.

Rainbow Dash smiled as Twilight sipped her tea and Pinkie placed some pancakes in front of her, happy that everything turned out great, all things considering.

“That collar looks so cute on you Dashie! Maybe we can ask Rarity to make you a nice dark blue one with your cutie mark on it, OH, or maybe Twilight’s cutie mark! That would be so adorable,” Pinkie gushed.
