Rarity was intrigued. Her best friend had been acting quite odd and, sending Sweetie Belle off for a day and night of fun with her little friends, the fashionista was ready to investigate. Trotting up to the castle, she played back in her mind what had been the last straw. "She looked positively hungry." Saying the words out loud, remembering the smoldering gaze Twilight had been giving her posterior, Rarity lifted a careful hoof and started to knock.

Spike had all his things together, even the special little shirt that was loaded with Twilight's enchantments. Predictably, somepony was at the front door just as he was about to head out and wait for the train. Waddling along on his two legs, he threw open the door, almost on the edge of annoyance at the interruption. "R-Rarity!" Spike's irritation was gone, blasted away at the sight of the mare he loved—even he knew it was puppy love, but who cared, she made his heart flutter.

"Oh, my little Spikey-wikey!" Rarity beamed at the dragon with her apprehension giving way to curiosity. "Are you heading out?" Her clever eyes roamed over the bags, over the case.

"Yup! I am going to another convention!" Spike was practically bouncing in place, "about to leave right now in fact…"

"I was here to see Twilight as well, was she home?" Rarity saw the slight tick in the dragon's features when she said the Princess of Friendship's name. "Is something wrong, Spike?"

"It's her and," Spike tried, he spent every ounce of his willpower trying to keep the name from slipping out, "Maud." He had no hope, not against Rarity's advanced forms of persuasion.

"Package!" Derpy bumped into Rarity from behind. "Oh, sorry! I have a package here for the Princess!" The mailmare held out a parcel toward Spike.

"You might as well take it up, I am going to be late!" Spike grabbed his bags and had to run on his little legs. "We'll talk when I get back, Rarity!"

"I'll take that, Darling. Oh look, it is addressed from Maud Pie." Rarity's snout curled up, she was certainly going to get to the bottom of this.

"Okay!" Derpy started to turn her head, one eye turning to watch Rarity, the other the direction she was already headed in.

"Spike are you still… Oh, Rarity!" Twilight beamed at her friend, the memory of the mare's "hidden" plot only vaguely coming to mind.

"We need to talk, Twilight." Rarity stepped in and closed the door behind her. It was time to try something bold. "I know all about it. I saw you in the street the other day, I know about Maud." The moment the unicorn said the name she saw Twilight jolt, as if she had only been peripherally awake. "So come on, let's chat."

Twilight's eyes, however, were glued to the package. The name of the sender was clear and she suddenly wanted to open it. "Wait, you know? But we were keeping it a secret!" If she knows we need to be fully honest with her. Twilight smiled at being in full agreement. "Alright, but I have to warn you, I am not going to stop seeing her."

Rarity blinked as her friend turned around. She followed Twilight all the way into the map room and parked her plot on her own little throne. "So, spill."

"I just love doing it, I can't… can I have my package?" Twilight had trouble focusing, she needed to know what Maud had sent her. Relax, calm down Twilight. Mistress didn't deliver it herself, so we can wait a few more minutes. Twilight immediately took a deep breath, then let it out.

Looking at the package, Rarity gave a nod. The package was gently retrieved in Twilight's magic and began unwrapping itself.

Pet, and Twilight. Enclosed within is a vial, you must inhale and then paint yourself with it the moment you think it safe. It is mine. I will be there tomorrow evening, so lock yourself up for me, I want my saddled filly all squirmy and ready.

Twilight blushed, her eyes flicking to the box, then to Rarity. "You know everything?" Rarity nodded to Twilight. "Well, I guess I am as safe as I am going to be." Twilight got the box open and pulled out the little crystal vial.

"What is-" Rarity froze the moment the cork was pulled. The scent that poured from within was mare, hot mare, horny mare. Ready mare. "Twilight!"

The scent was heaven, pure and simple. Rarity is still here, I think she is playing something. Twilight didn't care at this point, her Mistress' scent was heady, she closed her mouth and tipped the vial onto her snout, pouring it around her face and then dipping her head down and scattering the rest over her mane and down her spine. "Mistress…"

Rarity was in awe. Whatever the note had said, and whatever Maud and Twilight were doing, this certainly wasn't what she had expected. "I have to confess a little, tiny thing…" She tapped the bottoms of her forehooves together. "I might have exaggerated just a little when I said I knew what was going on… what is going on?"

Twilight, practically bathed in Maud's scent, felt an ache start between her back legs. She was, she isn't anymore. But she has seen us and I don't want to lie to her. "Maud is my Mistress, Rarity." Twilight felt a weight ease off her chest to tell somepony. "Her voice speaks to something in me, I can't fight it… well, I can, but that would ruin the fun."

"I...see…" Rarity's nose twitched. "And what do you two… do?" Rarity blushed hotly, she couldn't believe she had asked that. As she wrestled with her thoughts Twilight stood up and started walking toward her. The scent of "mare" got stronger, along with an undercurrent of something else.

Take her hoof. Twilight reached out with her magic, lifting Rarity's limp hoof. She smiled at her friend and started to turn. Place it on Mistress' belt. Twilight already had an idea how to do this, but Pet's words helped her make up her mind.

Rarity's shock when her hoof was guided to Twilight's flank and she felt… something. "What in Celestia's name is this?" Curiosity drove Rarity to trace the line of the invisible device, up and just under Twilight's arched tail. She felt the split as part of the belt dove down between the mare's legs. She had an idea just what it was. "Twilight! How long has she kept you locked up in this?"

"Since we met." Twilight looked back over her shoulder. Mistress must have put something extra in her scent, something that is making us… mmm. Twilight gave a little nod. "She doesn't keep me in denial, she feeds my hunger." The smell was eating at her resolve, Twilight would soon be futilely prodding at her belt, lost in need.

"But… this is locked on!" Rarity jerked her hoof back finally. Something intrigued her, but first she had to know something. "Twilight, is she controlling you against your will?" Twilight giggled and shook her head. "Twilight!" Rarity charged her own horn, then let her magic pour out in futility.

"I gave myself to her, Rarity. Maud is the best." Twilight leaned to the side and flicked a wing out; she had hit the limb with the scent and now started rubbing her cheeks against it, drinking it in along with the aphrodisiac her Mistress had sent her.

"Okay Rarity, you can figure this out. Maud is an earth pony, there is no way she could have overpowered Twilight… You really gave yourself to her?" Rarity watched Twilight nod to her; still seeking to spread the scent further. "So this is all consensual? Between two adult ponies?" Twilight smiled and gave a little nod again.

"Would you like to come and watch, Rarity?" Twilight saw the absolute shock on her friend's face. She knew she felt it too, Pet had taken control for just a moment. It wouldn't hurt, not for her to watch.

Rarity should have said "no" and run to tell… "Who would I tell about this? 'Twilight sparkle has a marefriend who likes to play games!' It wouldn't work at all… what did the letter say?"

"Mistress told me I have to go and bind myself up, she will be coming tomorrow night." Twilight did the math, or tried. It will be a lot of hours. Twilight beamed at that. Ask her to watch again, she wants to. "Would you… like…"

"Yes!" Rarity couldn't believe her motor was running. How it had gotten started she didn't know, there was nothing around she would conventionally find "sexy". By the time she had her thoughts under control Twilight was already walking, leaving her behind. Rarity did the least graceful thing and trotted after Princess Twilight.

Twilight walked into her bedroom and, leaving the door open, made her way straight for the harness. "Come in and close the door."

Rarity did as bid and entered. Her eyes tracked and focused on what Twilight was walking toward. "Kinky tack? This… this stuff is expensive…" Rarity moved over to stand beside Twilight.

"Put it on me, Rarity." Twilight squirmed at the thought of her friend binding her up. "Either put it on me or leave." Twilight grinned as a blue glow grew around the bridle. Closing her eyes and opening her mouth, Twilight felt the bit press against her snout first. She pushed her head forward, working the bit in firmly. She was gagged, but her friend hadn't locked everything on. Twilight half turned to look at Rarity.

"Oh, sorry, trying to work out how to fit this. There are far more straps than a fashion halter would have." Rarity fumbled quickly and got the bridle sorted. Pulling it over her friend's head, she pressed the first of the little clasps together, hearing it click most assuredly. "Are these locks?" Twilight nodded slightly, not wanting to disrupt her outfitting.

Rarity was hot now, she realized she was most assuredly into this. She likes this, Twilight. Your friend likes putting our tack on us. Twilight blushed. She couldn't see so wonderfully now, not with the blinders blocking her peripheral vision.

"Darling, I simply have no idea how this goes on!" Rarity was inspecting the saddle, trying to make sense of the straps. Purple magic lifted the gear up, hefting it over Twilight's back and setting it in place. "Oh, that is where they go? I think I can manage now." As Rarity worked, Twilight noticed something, she was too gentle-hooved with the tack; so she decided to teach the unicorn. Jerking away, while Rarity was halfway through fastening the girth, Twilight glared at her friend.

"What's wrong, Darling? Too tight?" Rarity had been as gentle as she could be, the outfit seemed very improper for a mare who is a princess to wear. Twilight shook her head and Rarity's eyes bulged. "Too loose?" Nod. "Oh Celestia… hold on."

Straps of thick rubber started pulling tight, tighter even than Mistress pulled them. One strap by one, Twilight was soon firmly bound into her tack; it let Twilight refocus on the scent of her mistress. Something built, an ache, a need. Twilight trotted for her bed but, just as she got close the need overwhelmed her.

Rarity watched as Twilight fell sideways onto the bed, her forehooves curled and tried to get to her back legs. The rubber tack pulled tight and the mare was denied even the attempt to try to reach her trapped vulva. "Oh my sweet merciful Princess…" Rarity watched as Twilight started to grunt, buck and squirm. The alicorn was panting hard and whimpering, desperate to reach her body, to get relief.

Let me have control, Twilight, you can relax and sleep. Pet was gentle, always gentle, and Twilight didn't resist as her other half took over. The agony of need spiked into pure pleasure and Pet whinnied again and again, wearing herself out in the bondage setup, ever spurred onward by the scent that clouded out everything now, but need.

Not quite sure when she had started, Rarity had reached back with a hoof and started to stroke herself. She watched as her best friend struggled until exhaustion, and she kept rubbing.

"Beautiful, isn't she?" The flat monotone startled Rarity so much she jumped in place, pulling her hoof away. "You aren't helping her get free?"

Gears turned, but lust had them clog up quickly. "I… I… she asked me for help…" It was all Rarity could manage at the moment; of course Maud had come in moments before she was going to get relief.

"Go home, Rarity." Maud gave Twilight's friend a look that spoke volumes. "If you want to learn about this, about either side, come back in the morning." Rarity's hooves flashed and she bolted for the open door.

Maud sealed the bedroom once more and climbed onto the bed. "Now, Pet, you get it at the source now." She lay down, her vulva pressed to Twilight's snout. Maud's pet began licking with her magic, nearly immediately.
