"Hrmm, Sedimentary…"

Twilight remembered those words, they echoed in her head as the first words Maud had said in her presence. She trembled just at the memory of that amazing voice. Every word, every syllable, tickled all the way down Twilight's spine and tickled her— Good fillies don't think about that place!

Panting a little, Twilight reached up to press a few odd strands of crazed mane back into place. She was working herself up way too much over this, she knew, but she wanted to make the perfect impression. There came a knock at the castle door. She's here!

Trot, just keep an even pace, don't look too eager... Twilight galloped halfway to the front door, then teleported the last bit of the way. Her magic grabbed the door and opened it. "Hi Maud!" Twilight's voice cracked halfway through the greeting. She blushed.

"Hello, I like your castle, it is built on bedrock." Maud reached her hoof down and rubbed at the stone that the crystal walls sat on firmly.

Twilight froze, the slow, even voice ate at her focus, it pulled her back to the time when Maud had told her poetry in that same, slow voice. I should relax more, calm down. "Come inside, Maud."

Maud blinked slowly at the alicorn. "Do you remember what I told you?" The earth pony followed her host inside.

"I do…" Twilight's thoughts echoed with the soft voice, it resounded. She half closed her eyes and stared ahead. "Twilight sparkle," her own voice took on a low, even tone, "if you want to be a good pet, invite me over and greet me by saying 'Hi Maud'." Twilight froze in place, the voice echoes had stopped. "I… but…"

"You want to be my pet." Maud walked past the other mare, slowly moving in and looking around. "These rock floors are heavy slate, I can count the layers if you like?"

"I… pet?" Twilight tingled all over. Maud's voice wasn't affecting her anymore, she was more clear-headed than she had been in her life. Do I? I feel… great, and all she did was talk to me.

Maud turned and looked at the alicorn. "This is your choice, if you don't want to be my pet you won't relax as I count the ten layers in this slate." Twilight's ears perked forward, her heart beat faster and faster as the earth pony gave her the choice. She closed the door and started walking closer. "Ten," the moment the word was out of Maud's mouth, Twilight knew she had actually been given the choice, that her mind had a choice.

No it didn't, I want this too much to not do what she says. Twilight almost missed the next number, her brain was sparking in discordant voices.

Maud's expression never changed. "Nine." The voices seemed to go a little quieter in Twi's head, her ears strained forward. "Eight." Twilight's legs felt a little wobbly. "Seven." Her legs gave out, slowly. The alicorn folded her wings down against her as she lay on the stones that Maud was counting.

Pacing around Twilight, Maud reached a hoof out, almost-but-not-quite stroking the Princess' mane. "Six, I started at the top, we are getting deeper." Twilight's belly pressed down against the slate floor, her muscles giving out completely. This is better than the best massage I have ever had. "Five." Her head was much quieter now, the voices telling her that she was too important for this, that she shouldn't, getting quieter and quieter. "Four." Her head was silent. Not silent, just waiting, listening.

Twilight barely heard as Maud said, "Three." Twilight closed her eyes, it seemed right. Everything was too heavy to worry about now. "Two." She smiled, only feeling good about how calm she was, like the stones under her body. "One. That was the last layer, Pet."

Pet… Pet… Pet… Twilight smiled more. She didn't need to see, she didn't need to move.

"You know I am going away, it will be in one day's time, and last for a week. We are going to set you up just right. When I come back, you can make your final choice." Maud reached a hoof out properly now, stroking the alicorn princess' mane. "What are you?"

Feeling her mouth freed from the lethargy, Twilight smiled as she spoke. "Your pet." This is amazing...

"You are, but until I return you are perfectly capable of thinking and making up your own mind, if you want to be mine I will play more. If you want to go free, I can show you some things that might make you happy as well." Maud was stroking the mare's mane repeatedly now. "First thing we need, is a little hypnotic suggestion."

Hypnosis! That is what this is! I always wanted to try hypnotizing somepony… wait, am I hypnotized? Twilight pushed against the strain all around her, the weakness. She pressed her head up against the gentle hoof with each stroke.

"While you are my pet, Twilight Sparkle, you will hold your tail high, make sure everypony sees under it." The words were out of Maud's throat for a moment and she saw the alicorn's tail arc up higher. "More, higher, Pet." It rose even further. "Good filly."

The words drove fireworks into Twilight's brain. I am a good filly! She strained the muscles around her dock, she had never really worked them so much before, but Maud said she would do it, so she must.

"Twilight Sparkle, as long as you want to be my pet, this will be your role. Want to be my pet and you are, do you understand?" Maud was in no small way excited, although she barely showed it. She had played with friends before, but to have a princess, an alicorn. The barest of twitches flicked through her tail. "If you are in danger, or anypony else is, you will not be my pet until you and they feel safe again, do you understand?"

"Of course, Maud." Twilight's mind was active, she could understand the wording of Maud's and it was unbelievably simple and complete. "I want to be your pet, so I am. While I am your pet, I need my tail to stay up." The hoof stroked a little more firmly.

"You are a good filly, Twilight Sparkle." I am a good filly! Twilight's inner voice, and Maud's, worked together, in tandem. "But you mustn't call me by my name when we are alone together. I am your Mistress, Twilight Sparkle. If you are my pet, and we are alone, you can only think of me as 'Mistress'." I am a good pet, Mistress, I promise!

"Yes Mistress." Twilight was smiling wide, her tail struggling to be held up now. "My tail is heavy."

"Good filly, you should always tell your Mistress when something is hard, or wrong. And Twilight Sparkle?" As Maud said her name, Twilight felt her real self surface through the persona she and Maud were building for her. Maud saw this too. "If you ever don't want to do something, tell me 'Too Cheesy'. Do you understand, Twilight Sparkle?" Twilight nodded, the word settled into her head, she felt it was reachable no matter how deep her Mistress would put her. "And furthermore, if I am not around, and something is too much to bear, Twilight Sparkle, you will not be my pet until I return."

"Thank you, Mistress!" Twilight's own voice sounded odd, a little flatter. "Mistress?" She said the word just to hear herself say it.

"Good pet, good filly." Maud stroked Twilight's mane. "Now, when a pet lowers her tail, did you know an unbelievable need fills her? Fills her with an ache to be stroked, an ache to be filled? Did you know this, Pet?"

Twilight gave the tiniest of nods. "I do know this, Mistress."

"Good, Pet. Let your tail dip, just for a moment." Maud gave her pet a test and she watched as Twilight's tail fell a touch. The moaning, the whimpering, was music to Maud's ears. The hypnosis had all worked, she had an alicorn princess, the Princess of Friendship herself, as her willing pet. "Good filly. Very, very good."

Panting for breath, Twilight stared ahead. She had jerked her tail back up sharply. What was that? Why did I suddenly get flashes of stallions… of mares!

"Pet, does Twilight Sparkle know any spells to make something… harder to see?" Maud drove her first wedge into the knowledge that Twilight and "Pet" shared. "Does she know things about spells that could hide an object?" It was such a naughty thing, Maud planned. If this worked, it would be better than even the instructions already in her new pet.

Twilight's mind seemed a little fractured. She reached for the actual spell, but only got back vague ideas about it. "I think she does." Twilight spoke about herself in the third person, if her Mistress hadn't been the one to start it, she would have gotten worried.

"Wonderful, Pet. Now I need Twilight Sparkle to talk." The moment Maud said it Twilight blinked her eyes and looked up. "Twilight, can you make this invisible?" Maud held out one of her favorite toys, but the look of it usually meant that nopony could wear it for too long.

The device looked like a very streamlined set of metal bands. Big enough to go around a mare's waist, thighs, and press up between her back legs, the chastity belt was a little confusing to Twilight. "Now?" Maud nodded to the alicorn. "Okay!" Twilight began the spell, pouring power forth and forming it just right.

Maud was astounded as, sure enough, the belt faded out of being; if she wasn't holding it in her hoof she knew it would be gone forever. "Good filly, Twilight Sparkle. I want my pet back now." Oh thank goodness, I can relax again. It wasn't really being shut out, Twilight was the one always there, always in control, but when she was Pet she just didn't have as much control. "Stand up, Pet."

Stepping around the mare, Maud moved in behind her. "Do I get to wear that?" Twilight liked the idea, a lot. "How does it work?"

"It has some enchantments on it, Pet." Maud pulled the device open, lifting it up and over the alicorn's plot. "There were already some enchantments I had on it, mainly cleaning and such." Maud adjusted the belt and reached under Twilight, working by feel with the toy.

Twilight heard a click as the tight belt settled around her waist. "That feels tight." What does that make me feel? Mistress will want to know! "It feels really good!"

"That is very good to know, Pet." Maud kept using the title, knowing it would reinforce the control on the mare. Pulling the main part of the actual chastity strap down, Maud clicked it around Twilight's dock, pulling it down and between her back legs. "You are already a little excited, it will help with that." And it did—Twilight felt a tingling sensation, a nice tingling sensation, as the toy cleaned her moisture away.

Maud had a little trouble getting the strap in place. "You are a bit bigger than most mares, Pet?" That fact, as Maud knew, was because she was an alicorn. A princess. She finally got the latches lined up and a click sounded. "There you go, Pet, all safe and sound. Now, let your tail dip again, just for a moment."

Twilight was a good pet, she let her tail dip and groaned. All her thoughts scattered as pleasure and need exploded in her groin, the latter outweighing the former enough that she knew, she just knew, she would never reach climax from that alone.

"Keep it down a little longer, feel the need, Pet, let it have you, you can move if you wish." Maud set the test in motion. She watched as the alicorn collapsed to her side, one foreleg pushing back between her back legs, stroking feebly at the invisible metal belt. "Tail up now, Pet."

The moment she hiked her tail back up, the ongoing ache ceased and Twilight was panting, hoof still rubbing at the metal. "Mistress…"

"Yes, Pet?" Maud leaned down, setting her hoof just under Twilight's jaw. "Tell me what the problem is."

"There isn't a problem, I am just so happy!" Twilight lifted her nose back, pressed it forward to boop herself on Maud's hoof.

"Good filly. I should go, now, Pinkie wanted to make a cake… another cake. Boulder will keep you company, won't you, Boulder?" Maud lifted out the little stone that was her constant companion. "When pets look at Boulder, they feel really, really happy and good."

Twilight never heard the earth pony leave, she was staring at the shelf where Maud had put the rock. Her tail was hiked way up, although it was getting tired, even after such a short time. Tomorrow would be interesting.
