Starlight and Twilight walked down to Sugarcube corner with Mrs Cake in tow, they had no idea that they were walking into a trap but Starlight sighed as she said “I wish I knew how to get Sunburst to you know…”

“Ask you out?” Twilight said as she wrapped an arm around her “Look Starlight, I know it can’t be easy to be in your position but I’d suggest if you feel that strongly about him…ask him out” Starlight looked surprised as Twilight continued “Besides knowing him, he’d probably take longer to ask you out than….uhhh never mind”

Mrs Cake then whispered “I wouldn’t worry about it, dearies” as she opened the door to Sugarcube corner and then pushed the two in “Because you two….are now the love slaves of our Queen!”

Twilight and Starlight looked up from the Floor to see a pony standing before them “Nightmare moon!” Twilight gasped but then saw there was something different about her and then saw her friends kneeling around them bound and gagged “Fluttershy! Rarity! Applejack! Rainbow! Pinkie! Spike!”

The tall alicorn cupped Twilight’s face and said “My plan worked….and now your mine! Unlike Nightmare Moon…I have made no mistakes!”

“But aren’t you Nightmare Moon?!” Starlight asked as she tried to use her magic but it failed to work.

“No…oh no, Nightmare moon was born from the angry emotions of my host…I on the other hand was born from her desires! Her lust, her crushes….her most depraved thoughts! But also her desire to be stronger!” the alicorn said as the pink mist that surrounded her picked up Starlight and Twilight carrying them as she walked over to a mirror admiring herself but also admiring the bound mares around her including the mares suspended above her “I have feasted on her desires…they’ve been a delicious meal every time she got wet from thinking of every beautiful mare or handsome guard she fancied…or when she desired to be stronger or more productive!”

“You’re a leech!” Twilight snapped as she struggled against the mist “Nothing but a blood sucking parasite!”

“I’m simply the part of Luna that exists in all alicorns!” Luna laughed as she hovered Twilight closer to her “Including you, my sweet prize!” she kissed Twilight on the lips “You’ll be my greatest conquest!”

“Oh no, Luna my sweet…” Luna turned and found Celestia standing before her but her eyes were bright pink and she spreading an aura of lust through the room that made every mare wet. Luna’s clasped her hand over her groin trying to resist the urge to finger herself.

Luna said “What the mmmmm!?” Celestia’s magic closed her mouth gagging her “mmmmmm!”

Celestia walked up and cupped her sister’s face “You did exactly what I hoped you do when I took over your sister!” Celestia smirked as she fell to her knees and a slimy bright pink Fluid started leaking out her pussy. The pink fluid took the shape of a tall alicorn but with silvery wings and bright pink fur “ahhh that feels great! I can’t believe my plan worked! I have conquered Equestria by driving it’s rulers into fits of mad lust!”

“Who are you?!” Twilight snapped as she struggled still against the mist “Are you the lust!?”

“Yes…We like the nightmare take over our hosts and drive them insane with desire! My sister drove Luna insane and now we have all the most powerful ponies at our mercy! We are the sisters of desire, the slime ponies known as Princess Lusty and Princess Desire! I’m Desire by the way” the pink slime pony said as she cupped Twilight’s breasts and started groping her “And all of you are now our slaves!”

Luna gasped as a light greenish fluid started coming out of her pussy “AHHHHHHH!” she groaned as the slime pony gathered “mmmm”

“Ohhh my that was fun so much horny slut energy to feed on!” Princess Lusty grinned as she licked her lips “A kingdom full of mares and stallions! I can smell the feast! And with that dragon we can have some real fun letting him fuck that unicorn slut for hours!” she cupped Rarity’s face and kissed her “mmmm enjoy the heat slut!” Rarity gasped as her pussy became really wet “Ah! Now you Dragon…how about I keep my promise to you…fuck the bitch!” she used her magic to ungag Spike.

“I…I won’t!” Spike said as he looked away trying to ignore Rarity’s lusty moans but he couldn’t help it as his cock rose up in excitement “ARGRRHHHH NO! I’m not that kind of Dragon!” but Princess Desire still groping Twilight used her magic to silence him “MMMMM!”

“You don’t get it! We’re not interested in what you are willing to do! We are masters of magic that turns good caring creatures into sex crazed addicts!” she pointed to Twilight’s already flushed face “Look even your friend here is already becoming a drooling slut!” she let go of Twilight who lunged forward and wrapped her lips around Spike’s bulging cock “Excellent….now watch….you lot as I show you, your fate!” she groaned as she focused her magic “Ohhhh crap….this always….ahhhh” from her groin a long thick cock appeared “We need more slime ponies as the Storm King nearly wiped us out! You Sparkle and the other princesses will be our new breeders!”

“MMMMM!” Twilight mumbled happily around Spike’s cock “MMMMM!” she groaned as Desire pushed herself into Twilight’s pussy “mmmmm!”

Applejack suddenly asked “And the rest of us?”

“Oh don’t worry…we said this was to be all your fates!” Princess Lusty said as she turned to Celestia and cupped her face whilst staring into her eyes “Tell me how did you make Sparkle a princess?” Celestia’s horn flashed as she tried to show the spell but Lusty absorbed it “AHHHH YEEAAAHHHH!” Celestia lay back as the knowledge was taken from her “So that’s what it takes to make a breeding harem of Alicorns!”

Desire smirked as she could feel the knowledge too “Oooo that won’t be easy but damn I can’t wait!” she said as she pushed her cock in and out of Twilight’s pussy “If this one’s tight slit is anything to go by….making these mares our slaves will be a ton of fun!” She then had a thought “I assume Rarity will be our breeding slave too?”

“Of course but don’t worry…Spike will still be our favourite toy!” Lusty said as she then whispered “We maybe even able to revive the Slime Queen with enough Sex energy!” Lusty cupped Celestia’s breasts “Even this one will serve us well!” she leaned in closer “Now go tell your soldiers to spread the word of our rule, Sun Slave!” she let go of Celestia who rose to her feet and walked to the door before disappearing “Soon all mares and stallions will do as we want to spread our glorious sex slime over Equestria!”

Desire whispered “And then we’ll get our revenge on that Chrysalis bitch!”

“Indeed” Lusty said as she turned to Luna and grabbed her by the horn “And all this thanks to your horny slit! You will be my favourite slave!” Lusty however failed to notice the twinkle of defiance in Luna’s eyes…and it would cost her.

Author's Note

Okay yes I know my last outing into story telling wasn't good but I want to finish at least one story and this one seems to be the only one people like and I want the lemon scenes to have meant something...so there you go slime ponies, I just thought it seemed interesting like creatures similar to the changelings but hated them and the Storm King.

Now I have a question for anyone kind enough to read this "How would you like this story to end? With Luna breaking free or with her remaining a slave of the slime ponies? Or would you prefer Option 3, Bonkers option"

It's up to you but I fancy a bonkers option.
