"Much good that was!" Spike shouted in aggravation, as he got out of earshot of Fluttershy's cottage. "Well at least I was able to get it off my chest and talk to somepony about it... But still, she could've said at least a bit more than just 'um... I dunno what to say...'" He sighed hard at what he just said, feeling bad about it, "I shouldn't really hold it against her, I wouldn't know what to say to me either..." And with that, he felt a regular feeling of something coming through his throat the opposite way, coughing up a scroll Princess Celestia had sent him.

He opened the parchment which said:

[i]Dear Twilight Sparkle,

I trust that your research in the magic of friendship is going smoothly. However, the reason i am sending you this message is because a matter of royal business has again returned that requires the assistance of your assistant, Spike.

I have sent a carriage to arrive in one and a half hour s time, and let me assure you that the matter will be taken care of within only a few days and he shall be returned to you within the week this time.

Your tutor, Princess Celestia[/i]

After reading the letter, Spike sighed in relief, "Good! She'd be crazy if we were doing any more of that 'camel-sutra' stuff again... I still say we got lucky my wounds healed within a month... Well better get back to Twilight and give her the message, and maybe get at least a little bit in before I leave."

It took a good fifteen minutes before Spike got back into town, still another fifteen before getting back to the library when Rarity surprised him, "Hey there, lover boy..."

Spike jumped, not expecting to see her right now, "Oh, hey Rarity. What're you doing out here at this hour?"

"Oh, I ran out of a certain fabric that got our love juice all over it... I couldn't very well use it for a customer's dress now could I?"

He chuckled at the thought, "I'd think you'd save it for something a bit more... personal..."

She blushed, having already used a portion of it on half of a pair of lingerie she was hoping to show Spike before their next session, "Oh I wouldn't dream of it... so where are you off to in such a rush?"

"Oh, I have to give a letter to Twilight from the Princess, apparently she needs me to come to the castle for a few days..."

"Oh..." She replies in a saddened tone, "So you and her will be in Canterlot..."

"No, just me... Like the time you, her and Applejack had the sleepover..."

"Oh, now I remember. She did say something about you going to Canterlot for 'Royal business' or something..."

"Yes! And that's what's happening now!" Pausing for a second to look her in the eyes, "I would never leave you if I had the choice. You know that don't you?"

Her heart melted, "Oh Spike... How could I ever have doubted you?" She embraced him in a big hug- not a friendly hug mind you- but one that has lots of kisses.

Having the time of his life, he regretfully broken the kiss, "I should really be giving this letter to Twilight..."

"I... I know... just..." she started, but was stopped by his claw to her lips.

"I won't be gone long, and when I'm back..." he leaned in to whisper into her ear sensually, "You might want to close the shop for a few days."

"Alright, and I guess I've also got to go and finish a few things so you can fulfill your promise..." She happily replied through her giggles of anticipation as she walked back to her shop, excitedly thinking about what they'd do when he got back.

Spike was skipping his way to the library. He arrived earlier then he thought, and after opening the door, he was greeted by Twilight, "Welcome to Ponyville's Library, how may I... Oh hi Spike!"

"Hey Twi... I really hate to be the bearer of bad news, but I got a message from the Princess..."

"Oh my... what's wrong?"

"Nothing, except that she needs me to go to the castle for royal business again." He said in a sad manor, not wanting to leave Twilight or Rarity for even one second.

"Oh..." She replied in an equally disheartened manor, "Well, let me see the letter then, and I'll make a reply."

"Alright," Spike said as he gave her the letter. "But you know... The carriage won't arrive for a good hour, we could have a going away 'snack'."

"Oh Spike, you know I'd love that more than anything, but we still have a lot of chores we need to finish..."

Twilight regrettably said as she pointed to the piles of books accumulated around the library.

"Oh... I guess I shouldn't have dallied after visiting Rarity..."

"Well yes, it wouldn't've been half this big then..." And so, the next hour was spent cleaning up the library while they exchanged pleasant looks at each other and a little after they assumed, they heard a knock at the door, "I'll bet that's your ride."

"Alright Twi, I'll see you in a few days." Spike replied as he grabbed his travel bag and kissed Twilight.

"Have fun and be safe!" Twilight yelled as the carriage rode into the air, flying past the village in a matter of minutes, reaching sweet apple acres in near record time. The rest of the journey was uneventful like they always want them to be, arriving at the castle courtyard precisely on schedule, as both Princesses stepped out of the hallway to greet Spike as he exited the carriage.

"Greetings Spike, I'm so glad you could come!" Celestia humbly said.

"Yes, it is most wonderful to see you here Spike!" Luna replied. "What is the nature of your visit?"

"I invite Spike to come to the castle every few months to discuss certain matters with him." Celestia answers, in a more serious tone.

"Oh, I see. Then I guess he won't have much time to do much else..." Luna commented dejectedly.

"Well I am going to be here for a few days, I'd love to hang out with you," Spike happily said.

"Plus it's nearly sundown, so I will be too busy moving the sun and moon to see to Spike. So you two have some fun."

"Yay! Thank you sister!" Luna proclaimed as she grabbed Spike and ran back into the castle to chat with him and play some games.

It wasn't until hours later when Spike was sent to his 'bed' in same guest room Twilight had been in when Celestia saw him again, "Spike? Are you still awake?"

"Yeah, I couldn't sleep. At least not without you."

Hearing that made her heart melt, "aw... Well I'm here now, andIi don't think there will be much sleeping tonight."

"I know. So do you want to get started?"

"Oh, not here, my bed is much more comfortable."

Spike couldn't help the smile emerging across his face, "What if Luna finds me asleep in your arms?"

Celestia giggled at the thought, "Let's just say she isn't a morning person." And with that they both sneaked off to her bedroom, barely passing through the hallways without arousing attention from the guards, and sneaking past the guard at her bedroom door by the classic 'throw a pebble to get his attention', which amused Spike when it worked.

"You know we don't have to do this every time, right?" Spike said whenever they were safe inside the Princess s bedroom.

"But it's so much fun!"

"Heh, can't argue with that!" Spike agreed with a kiss planted on her lips, "Now how about we stop all this talking?"

Celestia just smiled and nodded, leaning back in to an even deeper kiss. She had always loved the feeling of Spike's forked tongue swirling around her mouth and around her tongue, lightly moaning as their lips pressed against each other. The gentle and strong touch of his claws as he guided his hands around her head and through her mane put her into ecstasy, driving her already soaked plot into overdrive. She moved her hoof down, fondling Spike's crotch, waiting for him to increase his size to start the full course she was needing.

"Not yet..." Spike whispered between breaths, watching the royal princess practically beg him, "It may take a bit, I've already done it with three mares today."

"What?" she practically yells, thankful that she has a spell preventing sound from escaping her room. "How... Who... Explain yourself!" Clearly losing most of her arousal.

Spike was in panic, thinking to himself, 'Oh god, why did I say that?' "Well..."

"I'm waiting..."

"Well Twilight spent the night with Rarity after a party, and the next day Rarity asked if I could do those things with her..." Spike started, not noticing Celestia's expression when she remembered how similar the situation was compared to her own, "and it was really good, but I couldn't help but feel guilty, so I took a walk where I ran into Fluttershy," Celestia's eyes widened, never expecting Fluttershy. "I would never have thought she would get so hot and flustered... she wouldn't even listen to me until I fucked her till she couldn't stand..."

"A... And how long ago was this?"

"You sent me the letter as I was coming home from Fluttershy's..."

"You took two mare's virginities today?"

Spike couldn't help but lower his head, becoming sadder and sadder, "Yes... but I still haven t done anything like that with Twilight..." Finally breaking into tears, "I'm a horrible dragon!"

"No, you're not! Only a horrible dragon wouldn't think he is..." The little dragon wiped his eyes, not saying anything as the princess continued, "You care about Twilight enough to cry for her... you bare all of this just to spare her feelings... you are the kindest, sweetest, most generous, and most honorable dragon i have, or ever will meet."

"Really?" Spike asked, sniffling up his remaining emotions.

"Yes, and just for you, I will do anything you want me to do..."

"Well..."

"What is it?"

"I'd like to kiss them when I'm making love to them..." The princess lowered her head and sighed deeply, "What's wrong?"

"I have been looking for a spell to allow you to grow in length just for that reason since we started this. But the only ones I could find were permanent..."

"Oh..." Spike replied, lowering his head.

"However, i have found one that can transform a mare into a filly for a pre-determined time. Making us the perfect size for you..."

"But if you're turned into a filly..."

"Don't worry, only the size of the body changes, nothing more. We will still be the ponies you love and care for, only small enough for you to hold in your hands comfortably."

"That's amazing! But wouldn't I have to have to make a unicorn cast the spell in order for it to work?"

"There's the catch! It's actually a special natural remedy," she claimed as she opened one of the cupboard drawers and lifted a bag out with her magic. "All you have to do is mix this within any drink and they will be transformed into the perfect age for you," she continued, handing him the bag.

Spike excitedly opened the bag and dug his hand in to grab the substance, "What? They're like little pellets?"

"Yes, each pellet lets a pony stay in their new state for ten minutes, and they have no taste, so you can throw as many as you want into even a cup of water and they won't notice."

"How do you..."

The princess giggled, "I poured almost an entire bag, I couldn't taste any of it, and I was a little filly again for almost two days," Laughing at her own pervious predicament, she leaned down to Spike, "But make sure she drinks ALL of the drink, or she may transform back hours too soon."

Spike looks back into the bag in silence, then looked at the glass of water precariously placed on top of the nightstand, "So what are we waiting for?" Celestia almost giggled with glee and anticipation as Spike grabbed a hand full of the pellets and eased a few into the water. The pellets almost instantly dissolved, quickly shrinking it's dark green appearance into nothing, one after another as the last of twelve plopped into the water. The instant his hand was empty, Celestia's magic grabbed the glass and she drank every drop in one quick gulp, slamming the empty glass down and starring into Spike's eyes with a lustful gaze, scooting closer and closer to him and planting a kiss on his lips, deep and passionate enough that Spike closes his eyes to enjoy the feeling. After only a few seconds, Spike felt Celestia's lips change in a strange way, tightening around his while becoming easier to mold with his mouth. Spike opens his eyes, and looks back into the closed eyes of the princess, too entranced in their kiss to notice as his claws reach around her head and slip through her mane again, this time it did not take any effort to reach. His hand continued down her back, swung around towards him, and reached the base of her tail with only a small effort. He broke the kiss, and looked over the young filly in front of his eyes, "Wow..."

"See, I told you. The perfect size." She said as she stood up and looked him straight in the eyes.

Spike blushed slightly and looked away, "I kinda feel like a criminal for doing this..."

"Nonsense. Sure it's a filly's body," she proclaimed as she pushed him down and got on top of him. "But I'm still the same in EVERY other way!" She lustfully finished, aligning his cock with her hoof and slamming it as deep as she could. Spike couldn't describe this feeling, it was like all the other times he's fucked her, all the little keys her pussy has, all the sensitive spots she has, only tighter, and more proportional to his natural self, though he still had to enlarge his member. "Are you doubting it now?" Celestia asked, having been riding him for a few amazing minutes now.

"Ahhhhhhh... Noooo..." Spike complied, too focused on the pleasure to fully respond.

"Now kiss me!" She demandingly shouted, planting her lips on his with amazing force for her small body, practically flattening him on the bed as her hips continued to slam down onto him, both moaning in pleasure into each other's mouth.

The newfound pleasure was growing too much for Spike, as her tongue invaded his mouth like no other pony before; his hips gained a mind of their own and started thrusting deep into the filly's very core in time with her bouncing on top. Celestia broke the kiss, leaning back with her mouth wide open, as if screaming as Spike drove more and more into her, she could not find any word or moan or groan to say, until Spike spoke up, "Oh Celestia! I love you!"

Pulling himself onto her neck, Spike started nipping and kissing as much as his mouth could, which drove the princess over the edge, "Oh my... SPIIIIIIIKE!" She shouted, convulsing around his cock tighter than a vice, which set him over the edge as well, unloading a massive load inside of the filly princess.

After their orgasms subsided, Celestia fell over with Spike still inside of her, nearly falling asleep in his arms, which were wrapped around her in a loving embrace. Spike took his head from her neck and looked into her eyes, "Can we lay here for a while?"

"I would love that," The little filly said with a kiss as they fell asleep in each other's arms.
