Formicidae, the changeling infiltrator, managed to get himself deep into enemy territory to spy on the pony princesses. His disguise as palace staff was working beautifully, Celestia’s personal maid mare. It allowed him to easily make weekly reports for the true ruler of the changeling, Queen Chrysalis, as well as making sure to have a readily available food source with how many pent up guards were stationed in Canterlot. “Lace Doily” had just finished sending her most current letter out, smiling as always as she walked out of the post office before going home to her little apartment. The next day saw her back at work in the presence of the solar diarch as usual. She did her cover work and tended to the princess’ bidding, cleaning, bringing her tea and her daily slice of her favorite cake to go with it. Lace listened to much more than the princesses’ thoughts though, taking mental notes on things such as scheduled diplomatic visits from various nations as well as plans for reallocating funds from the guard for various other charitable functions. Aside from a few things she would make sure to include in her report, the day was bland and boring.

Lace woke up the same as she had for the last couple of years and got ready for more boring espionage. The palace staff seemed much more energetic today than any other and it had Lace curious as to why, to her horror she soon learned why from Celestia. The false king Thorax was on his way for a visit with the royal sisters. She had to get out of there! That disgusting moose beetle could ruin her cover and she needed to find any excuse to get out of work now! She racked her mind for what to make up and when the idea hit her she started to approach the princess only for the royal trumpeters to begin playing, announcing the arrival of that nymph slime colored abomination. Lace was doing her best to keep her panic hidden and stop her sweating but it was noticeable by some of the other staff as well as the princess herself, who with her caring nature whispered to Lace. “Are you doing alright Miss Doily? You seem a bit upset.”

This sent red flags firing through her mind before acting quickly, her wit going full force as she concocted a brilliant lie on the spot. “I’m sorry Princess...But the changelings still make me uncomfortable. I know they are reformed but I still can’t unsee the wedding invasion when I look at them. It’s stupid and racist but...I’m terrified of them.”

Celestia gave her personal maid an empathy filled smile and nodded. “Then take the day off, I think I can manage a single afternoon without you at my beck and call.” This was the perfect chance for her to get out with her cover intact! She thanked her highness profusely before making her way towards the exit, all but running passed the antlered bug pony on her way, catching an awkward glance from him as she made her exit. Lace ran home as soon as she could and locked the door behind her as well as closing all the blinds before the disguise of the mare burned away.

“That was WAY too close! That damned traitor could have ruined years of undercover work! Thank the Queen that Sunbutt is so caring or else I might have been torn apart by angry guards there.” Not wanting the day to be a complete waste he began working on his report, the surprise visit from Thorax would be something Chrysalis would be interested in knowing about.

The next day started much the same, Formicidae putting on his Lace disguise and leaving for the palace yet again. She wore a cocky smile on the way, she still had her cover despite the near disaster. Many of the staff gave her words of encouragement after rumor of her reason for taking the day off prior had spread, the little wisps of empathy were a wonderful snack for her as she made her way to Celestia’s personal chambers. The princess was there waiting for her with a pot of hot tea. “Lace, please take a seat.” She obliged as Celestia floated a cup over to her, the hot leaf juice still steaming. “I know yesterday was vexing to you and I wanted to make sure you are doing well after that encounter. You are far from the only pony still afraid of Thorax’s hive.” Lace let out a feigned sigh and sipped from the hot tea, a mint blend and one of the few the disguised changeling enjoyed.

“I’m sorry Princess...It was unprofessional of me to let my feelings towards them affect my performance, but after the invasion...It’s just been hard to adapt to them.” The princess gives a knowing nod before sipping her own tea.

“Please, drink up, I’ve always found tea to help keep me calm and level in some of the most stressful times.” Lace obliged the princess before letting out a loud yawn, finding it difficult to keep her eyes open.

Formicidae eyes fluttered open and he let out another loud yawn, his mind a bit cloudy as he tried to shake the sleep from his brain. Then he became suddenly aware that he couldn't move his fore or hind legs as well as being unable to bring up his disguise. He looked around in a panic to see he was still in Celestia’s chambers and tied to a chair. “Well, seems my maid is finally awake.” He froze. Celestia walking around to in front of him with a very unamused look on her face. “Now little spy, you have answers that I want.”

His heart was pounding in his chest as the words struggled in his throat. “I-infiltrator zero four seven F-f-Formicidae. That is all you’ll get so you may as well toss me in the dungeon to rot!” He did well in putting on a brave facade and truly was ready to be sent away to never see her sun again.

“That’s most unfortunate, but ,sadly, just sending you away isn’t an option until I get what I need from you.” She walked over to him, his facade breaking as he knew what came next. An ancient alicorn with endless years of knowledge and magic behind her wouldn’t take much to flay his mind for what she needed. He closed his eyes and grit his teeth and waited for the pain to come but it didn’t, instead he felt something pulling the panties he was wearing down then brush against his stallionhood. His eyes shot open to see Celestia nuzzling his sheath, causing his member to grow and stiffen.

“What are you do-mmmph!?” Golden magic wrapped around his mouth as the princess continued before she gave a lick from base to tip along the underside of his twitching cock. He could do nothing but give a muffled moan as she gave him a wicked grin before she enveloped half of his length in her mouth. Formicidae struggled against his binding futilely as Celestia fellated him. “This has to be some kind of wet nightmare! Wake up wake up wake up now you useless pile of chitin!” No luck as his throbbing cock leaked pre into the solar goddess’ throat and his tip began to flare...only for the pleasurable warmth and sucking stopped with an audible pop sound as she pulled back, leaving him aching.

“Now tell me where Chrysalis’ hive is!” She demanded of him and he growled and shook against the bonds and magical gag. “You won’t be able to resist forever and I willget what I want from you.” She walks away from him and stares him down for a few minutes, causing him to sweat a bit before making her next move. She backs up to him and pressed his stallionhood between her plump flanks, eliciting another groan from him. She started moving her ass up and down along his length, pre leaking down onto her soft fur. “Tell me what I want and I’ll give you something special.”

To Formicidae’s credit he held on. “To Tartarus with you sun tyrant! Y-you won't get anything from me!”

She smiled at him before speeding up, his peak approaching fast as more pre drools from his tip and his head starts to flare once more before she pulls away right before he could release. “We’ll just see how long you last.”

He lost track of time as her torture continued, bringing him a moment from a wonderful climax before stopping and letting him cool down. His mind was clouded with lust and a need to finish. The solar princess had been at it for hours, whittling him down to a malleable putty. She moved the chair onto it’s back before standing over Formicidae, her gracious teats hovering over his aching cock. She smirks at the changeling spy under her, staring into his unfocused eyes as he shakes and shivers. Celestia lowered herself just enough to envelop his shaft between her soft mounds before thrusting her hips, her teats rubbing up and down the pre-cum slicked stallionhood. It wasn’t long before his orgasm approached once more, Formicidae drooling as his poor mind was being shattered and his tip began to flare. “What will it be little bug, shall I pull away or will you tell me where Chrysalis is?”

He couldn’t take it anymore. He screamed at the top of his lungs, “The border of Yak-Yakistan! Inside the mountain on the Equestrian side! Please I need it!” He was in tears as drool puddled under the back of his head. Celestia gave him a kiss on the base of his horn and picked up her pace, causing Formicidae to finally blow, after hours of being built up he sprayed his hot seed all over, soiling his maid uniform and covering his face as well as almost filling his own mouth. She cut the restraints and let him crumple into an exhausted heap, panting and crying from the relief.

“I love interrogating spies like that, but it always leaves me wanting…” She began to touch her marehood with a hoof before her horn lit, the changeling suddenly feeling his strength return. He turned to see the solar diarch waiting for him, flank raised up and presented. “Tell me little changeling, would you rather go back to the Queen you betrayed, or continue to serve the royalty of Equestria?” It didn’t take much more convincing for him as his member grew to full mast once more.

“Long live the Princesses.”
