Luna smiled as she walked towards Rainbow’s home, she now had three members for her harem and as she looked round she could see a few mares she wanted to fuck. A cute mail pony flew past giving Luna a momentary glance up her skirt at her panties and she grinned. Another two ponies walked past their hands in each other’s pocket and Luna saw one had just popped a bon bon candy into the second’s mouth in a seductive way. Ponyville was filled with hot mares for Luna to have, surely as the princess there was no mare who’d refuse her but then she felt somepony walk up behind her. Turning she saw Spike, Twilight’s number one assistant and she gulped, he looked angry but why? She then remembered the few times she’d been in his dreams, some were about gems but most concerned Rarity offering love to him and true love, not the sexual stuff she’d done with the fashion pony but Spike wouldn’t know about that.

“I saw you….getting Rarity to….” Spike gulped and a tear trickled down his cheek “I love her and you just used her!” he snapped the last two words “Why?! Why did you force her?! She said she didn’t want to and….”

“Spike, I have been in your dreams and in Rarity’s dreams. She cares for you but not in a romantic way, in the way one might look down on a younger sibling. She thinks you’re childish and it’s just a phase that’ll pass soon enough. But we both know you want to spend the rest of your life with her and that feeling is unlikely to pass” Luna spoke plainly and then looked at the dragon who frowned “However I am forming a harem of mares but….if you help me get Twilight….I will help Rarity understand your feelings….I also promise to save a spot for you in my harem”

Spike looked at Luna for a moment and then Luna saw his eyes move down her body “Twilight? You want all of my friends?” Luna nodded slowly and Spike growled “I don’t want to be left out and you say you’ll help me express my feelings to Rarity? I thought at the cottage, she was into mares and…” he sniffed as a tear leaked down his face.

“She’s into both, she’s a very special pony and I know you’d look after her” Luna said as she leaned down and whispered seductively “You big strong dragon with the heart of gold” she leaned closer and whispered “So do we have a deal? You help me get Twilight between my legs and you get a chance to express your desires to Rarity?”

“On one condition…come with me” Spike said as he grabbed her wrist, gently encouraging her to follow him, which she did, he walked with her to a secluded spot in the park, Luna suspected what Spike had in mind and raised a shield so they wouldn’t be interrupted Spike stopped, pulling his shirt off revealing his toned upper body and said “As I see it, you owe me one for letting you have Rarity first….and giving me a rock hard boner” he said as he pulled down his trousers revealing his dragon dick, it was longer and thicker than your average stallion cock but what made Luna gasp was the little bumps that went up and down it “So…I want to punish you with it!”

“Oh, wow, it’s amazing” Luna said as she got on her knees, licking her lips, she couldn’t wait to suck it but Spike’s clawed hand stopped her by grabbing her horn. She tried to pull her horn free but Spike turned her round and pushed her down, her ass in the air. She looked back as Spike pulled her dress away and traced a scaly finger across her folds, before licking her love juice off it but he paused to listen to her pleading “But Spike I need to lube you up!” realising what Spike had in mind “Or…or….please!” she wanted to lube him, this was fun, Spike was so dominating and in control, she had considered making Pinkie her domination mare but Spike did the job so much better “Please…be gentle”

“I said this was a punishment….so you’ll just have to grin and bear” Spike said as he pushed his cock into Luna’s pussy roughly and groaned “So tight….you’re the first mare I’ve been with but damn it’s tight!” he leaned forward and began to play with her breasts “So big, you must….”

“Spike! What the buck are you doing?! Stop that!” a voice screamed the two looked to see Rainbow Dash just outside the shield. In her tight training uniform, her breasts weren’t as big as the other members of the main 6 but her toned body was so sexy that Luna gasped in pleasure “You’re going to be in huge trouble for this!”

“Ohhhh, Rainbow….you think….Spike forced himself on me?” Luna said as she let Rainbow in who flew closer looking crossly at Spike “I…I’m in full control…let me show you!” her horn flashed and Rainbow’s hands were tied behind her back. Rainbow began to struggle but Luna’s magic was in control of her “I’ve seen your dreams too, Rainbow, dreaming of Fluttershy licking your pussy, after you’ve defeated a thousand evil changelings but Fluttershy will never do that….unless you agree to something”

Rainbow gasped as her legs were spread in front of Luna’s face who reached a hand towards her concealed sex “Stop it! Let me go!” Rainbow snapped as Luna’s fingers traced round her pussy “N…no, Fluttershy….isn’t….in my dreams!”

“Spike, keep fucking me. Rainbow, I’ve seen everything in your dreams, you are a lustful little dash, you dream of Fluttershy, Twilight and Applejack in an orgy. Dream all you want because I can make that dream a reality and unless you join my harem, you won’t get in on it” Luna said as Rainbow stopped squirming and looked at her with a look that showed Rainbow was wondering how but then she nodded “All you have to do is join my harem as my own little Slave pony and an orgy is a guarantee. You’ll know pleasure beyond your evening spend touching yourself and any mare you want can be added to the harem. Your new name will be Rainbow Cum”

“I….I don’t know…why are you letting Spike fuck you if your into Mares?” Rainbow dash asked looking at the two as Spike thrust deeper into the princess.

“Oh, I’m into both, mainly mares but Spike here said I stole the love of his life so we made a deal. Maybe we can make a deal too? What say if she’s willing, I help Fluttershy see your feelings? I want my harem to be a place of love as well as a place of pleasure”

“Alright! Please, pleasure me mistress!” Rainbow moaned, Rainbow’s clothes suddenly disappeared, reappearing in a neatly folded pile next to Spike’s clothes “I’m all yours and…oooohhhh, sweet Celestia!” she moaned as Luna pushed her horn into Rainbow’s pussy “Oh yes, fuck me hard…”

“You heard her, Spike….harder!” Luna said to Spike but Spike stopped “What’s wrong?”

“Beg for it and tell me my role in the harem” Spike ordered as he grabbed Luna’s breasts, squeezing them roughly “Or else…I may just tie you to this tree and see who comes past”

“Please, master Spike! Fuck me like a bitch in heat, while I pleasure Rainbow cum!” Luna begged as Spike began to fuck her harder than ever “Ohhhh Rainbow, you have got to feel this….bastard’s cock! It’s so good!”

“Ohhhhh, your horn mistress Luna is so gooood, I don’t care…..” Rainbow moaned as she sat in mid-air, still suspended by Luna’s magic and suddenly gasped “Not my wings….mistress, they’re so sensitive!” Luna’s magic began to gently tease Rainbow’s wings.

“You don’t care? How good master Spike’s cock is? You need to be punished!” Luna tied her to the tree “No pleasure for you till Spike is ready to cum and you will drink his cum!” she smirked as Spike kept thrusting. Rainbow watched shifting uncomfortably trying to rub her legs together but her legs were tied to two separate branches, this denied her the pleasure and gave Luna a view of her wet cunt “Are you close, Master?” Luna asked ten minutes later.

Spike growled as he pulled out “Drag her to my cock!” he ordered as Luna untied Rainbow, grabbing her mane in her hand, she pulled Rainbow to Spike’s cock and spanked Rainbow’s ass “Spank her….make her moan. Do whatever you can to get her mouth open for me!” Spike ordered as Rainbow kept her mouth shut “I guess a sex slave pony with some defiance is fun”

“Indeed you’ve been a slave pony before…haven’t you Rainbow?” Luna said pushing a single finger into Rainbow’s pussy and teased her clit “You know how to make the game fun?” Rainbow nodded, now smirking and ignoring the trick the two had tried but then Luna started to play with her breasts. Rainbow moaned loudly for a moment before Spike’s cock was pushed into her mouth “There we go….her breasts are clearly sensitive…now fill her stomach with cum!”

“Watch it, Luna or I’ll fill your womb with my cum!” Spike said as Luna began to play with her clit watching her two latest harem members fucking. Both were smiling and Luna climaxed covering the ground with her cum “Luna, I have a plan to get you, Twilight but we need Pinkie Pie and while I finish with Rainbow…maybe you should go get her” Luna used her magic to see Spike’s daydream plan and Spike nodded

“Hmm shame, make sure you tie her up and take her along to my bedchambers tomorrow at 6pm” she said as dressed, cleaned her mess and kissed Rainbow’s clit before she made two outfits appear. One was like the costumes given to Rarity, Fluttershy and Applejack, except it was rainbow coloured and had some features fitting a slave pony. The second was a dragon sized tuxedo “Well you’re going to propose to Rarity at some point…why not after I show her how much you love her”

“Thank you, Princess Luna” Spike said as Rainbow nodded smiling on Spike’s cock “I’ll choose my own nickname though as Hardened Spike!”

“Hmmm not sure that works” Rainbow said, pulling her mouth off Spike’s cock for a moment and then went back to sucking.

“She’s probably right Spike but we’ll think of one….how about one last squeeze for the road” she said presenting herself for Spike to grope her one more time “Ohhh yeah!” she then walked away hearing Spike grunt as he came down Rainbow’s throat and then Rainbow protest as Spike licked her pussy “A dragon’s appetite for sex is so large it….will be so much fun…even Tia will get a go…once I add her too!” Luna laughed her eyes for a mere moment changing but she shrugged it off “Hmm strange”

Author's Note

Sorry for the late timing of this chapter I was experimenting with a few ideas, including a clop fic involving Principle Celestia turning into a lust demon and grabbing various characters to fuck from different franchises. Still I'm not sure how this worked out. Hope you enjoyed it and have a grant day.

Also Spike's nickname need one
