Rainbow Dash was excited as she waits in the royal bedchamber of princess Sunset. Which is very clean and seems hardly used, thanks to the fact that Sunset normally sleeps with her moms in their room. Thanks to her saving the day at the race The Best Young Flyers Competition, she has Sunset as her sex slave for a week. (1)

Of course she has to follow rules, which Rainbow agreed to as her moms stared down at her as they loomed behind Sunset. Sunset can take breaks when she's worn out, has to use the bathroom, eat, sleep, and other things. Which is why princess Celestia is in Sunset's room, using her desk to read over and sign forms. Keeping an eye on things, as unlike her or Molestia, or their sisters, other ponies can't control themselves, when they smell Sunset's scent. Sunset's herdmates have built up some immunity to Sunset's scent, thanks to being around her for so long. Celestia and Molestia are also resistant to Sunset's scent and that their mothering instincts being stronger then their lust.

“Alright, I’m ready,” Sunset said stepping out of the bathroom naked.

“We’ll get over here so we can start having some fun,” Rainbow Dash said as she had to take a bath first as Sunset doesn’t like dirty mates.

“Remember no anal or any of the rough stuff,” Sunset said walking to the bed.

“Don’t worry, I won’t,” Rainbow said.

“I’ll be watching,” Celestia said looking up from her paperwork.

“Right,” Rainbow said as she felt her cock going limp but got hard again as she focus her attention on Sunset.

“Here lick till, I’m good and wet,” Sunset said as she lays back on the bed and spreads her legs exposing her tasty cunt to Rainbow.

Rainbow could feel her 13 inch cock harden as the musk of Sunset’s cunt juices hits her. Even if she’s suppose to be the master here, she could help herself as her mouth waters and she crawls over to Sunset and plunge her head between her legs. Her tongue work hard at lapping up the sex juice coming from Sunset, which almost no pony could resist. The stuff is collected by her aunts who uses the sex juice as the main ingredient to make sex oils and drugs. And because of how little could be collected from Sunset, all the oils and drugs are highly expensive.

Which Rainbow Dash is getting to have her fill from the source. Rainbow like how Sunset didn’t have a pair of cock and balls to get in the way of her covering her cunt with her mouth, sucking away at the juices as her tongue drills deep inside to get the juices flowing. Each time that she cause Sunset to cum, a flood of juices hits her mouth, causing her to want more and more, making her to make Sunset to cum again and again.

Rainbow pulls herself away from Sunset’s cunt after making her cum at least ten times, Sunset was laying back panting as she recovers from the onslaught of pleasure she was given. Rainbow grins seeing what state she brought Sunset to, she got on her knees and pulls up Sunset’s up by her hips and press her cock up against Sunet’s well lubricanted cunt.

“Nice and tight,” Rainbow said feeling the tight walls of Sunset’s cunt squeezing around her cock. She knows she isn’t the biggest in either thickness or length, but she has the energy to keep going for hours.

Rainbow thrust into Sunset holding her body close to hers as she tries to fuck her brains out. Deep and fast just like how she likes it, with all the climaxes she gave Sunset it’s only fair that Sunset gets her off. She thrust fast and gave out a grunt as she started cumming inside Sunset, sending jets of cum into her. Rainbow sighed, satisfied, as she deposited her first load into Sunset.

Rainbow didn’t rest after cumming as she just started to thrust her cock into the now cum filled hole. As she fuck Sunset, she would lick up the sweat from Sunset’s neck liking the salty taste, and giving her a boost of energy thanks to Sunset being like catnip to ponies. The more they smell the higher their sex drive becomes, causing them to only stop once they’re spent and have no cum left. The downside was the crash that happens after the effects wear off like a sugar crash. Resulting in the ponies being very tired and hungry, not being interested in having sex till they recovered and their balls are refilled with cum.

Which is what is happening to Rainbow as she fucks Sunset hard and fast. Making Sunset to cum at least two times before, a load of cum is pumped into her by Rainbow. Who kept on hammering away at Sunset, pounding her rod into her cunt. Changing positions as she got to enjoy Sunset all to herself without any other ponies wanting a turn. Letting her cum repeatedly into Sunset, till at last Rainbow cum for the last time.

“That was great,” Rainbow said as she panted recovering from cumming so much into Sunset. She glance at the clock and saw they been going at it for 2 hours of sex, thanks to her fucking Sunset fast so they could have as many climaxes as fast as possible.

“Not bad,” Sunset said as she pulls herself off of Rainbow’s cock and crawls off of the bed.

“You can still move?” Rainbow asked as she was spent and could hardly move.

“I have to deal with a large herd who often just comes into the room to have their turn with me while the ones spent leave, recover and come back for more. I had to work on my endurance to not be worn out by all of that,” Sunset said as she was suddenly lifted up into the air and floated to Celestia.

“I help you wash up, we can have something to eat,” Celestia said carrying Sunset to the bathroom.

“Oh yeah, she would need lots of endurance just to be able to handle her herd,” Rainbow said as she lays back.

On one hand, she has Sunset all to herself for the rest of the week and gets to stay at the castle. But on the other hand, she was just one pony and at best she can only cum 10 times before her balls were empty. Sure she could continue with just her cunt but, she likes spraying her cum from her balls. Even with all of Sunset’s musk she couldn’t keep it up after reaching her limit, she needed time for her balls to refill.

“Well might as well enjoy myself here at the castle and once, I recover, I can go back fucking Sunset,” Rainbow said as she closes her eyes to nap for a bit.

!

For the rest of the week for Rainbow was spent fucking Sunset whenever she had the energy to do so. Once she was spent she would nap, eat the food that Celestia and Molestia made for Sunset. Turns out both sun sisters like to cook the meals for their night sisters when they change shifts and for Sunset whenever she was at the castle. But mostly from what Raibow has seen is that Sunset loves to nurse on her moms and aunts breasts milk. Which she has drank herself and saw why Sunset likes their milk.

Rainbow got to experience the royal treatment as she when she wasn't having sex with Sunset got to enjoy the perks of being a guest of the royal family. The maids would lick her cock and balls clean, which covered in Sunset's juices is something that the maids were all eager to be the one who got to lick it up. And she got to explore around Canterlot when she was spent and needed time to recover.

Rainbow during her time wandering around met with the Shadowbolts who are replacing the Wonderbolts in defending Equestria. Which Spitfire and the other Wonderbolts showed that they couldn't even help save Rarity when the wing spell wore off during The Best Young Flyers Competition. Rainbow had mix emotions about that, on one hand her heroes the Wonderbolts are now disbanded and are retraining to be Shadowbolts. But on the other hand, talking with Luna and Moon about joining the Shadowbolts, unlike what she would had to go through to join the Wonderbolts. She just have to pass basic training and she's in and because she is one of the Elements of Harmony she'll be joining the higher ranks as unlike the other ponies, she had already shown she is willing to risk her life to help others, instead of doing nothing when there is danger. (2)

Needless to say, Rainbow had a great week at the castle. Relaxing, getting the royal treatment, getting to fuck Sunset whenever she wants, and treating the whole thing as a vacation. But all good things came to an end as the week ended with Rainbow fucking Sunset as much as she could on the final day. Taking her time in fucking Sunset so that she could make her time at the castle well spent.

Then when she woke up she found Celestia, Molestia, Luna, and Moon all having their cocks pointed at her face. They explained that they been holding back for a entire week to fuck her, they had been watching her fuck Sunset and never once joining in on the fun. And now that the week is over, it's their turn to fuck her as much as they wanted.

"Yeah," Rainbow gulped as she could only sweat at the sight of the four massive cocks in front of her face.

Author's Note

1 - What would had happen if Rainbow Dash got to have Sunset as her sex slave all to herself for a week.

2 - Seeing how Rainbow had to work hard to just to join the Wonderbolts, when they and the other soldiers do nothing at all to fight the villains. Why would she really have to go through hoops to join. And saying that she needs to learn to take orders, means nothing when all the other soldiers will be hiding behind puppies when a villain appears and only act high and mighty when there isn't any danger to them.
