Starlight Glimmer blinked owlishly. Her brain was boiling with all kinds of knowledge that she had never believed existed before, but that now made her feel unbelievably hot, and sent tantalizing ideas dance around in her head. "Red, Yellow, Green." She thought of the words as concepts; they were representative of things she would want to happen, things she really wanted to happen, and things that fitted neither group until she actually wanted to try them.

"I know one of you is going to greatly enjoy this part." Cadance's grin was aimed at Twilight. "Right now I want you to make a list of five things you would like to do. They can be fantasies if you wish." The gasp from her sister-in-law confirmed Cadance's prediction. "Could you both do—"

"Done!" Twilight's quill had worked so fast the ink wasn't even starting to dry, but she had a list of her five things that she wanted to do with Starlight. "Should I read them out?"

"Not yet, Twilight." Cadance looked over to Starlight, watching her carefully scribe some things down. "I want you both to have your lists, and we are going to pick one thing from each to do first."

Starlight had just finished her list when Cadance mentioned that they would actually do one of the things. Her heart sped up and she stared at the words on the page. "W-W-We are g-going to do one of these?" The world seemed oppressively thick around her, and the words on the paper mocked her with their honestly.

"We are. Color check?" Cadance looked to Twilight.

"Green!" Twilight practically bounced in place.

"Yellow." Starlight was staring at her list, and so didn't notice the wings until one had curled around her from either side. She jerked her head up to see Twilight and Cadance had flanked her, and each moved in to support her. "I didn't realize that is what you wanted to do."

"Perhaps we should read Twilight's list first?" Cadance tried to read whether Starlight would want close comfort or space, and judged the former. She felt a slight nod from the unicorn, and looked across to her student. "Twilight, your list, and why you chose each item?"

"Rope bondage!" Twilight was at the first item in her list. "Every time I see Applejack swinging a rope I… I shudder a little. I imagine wrapping a pony up with it, tying them just so." She squirmed in place and adjusted her wings a little.

Starlight's attention was riveted on Twilight now. She looked at the mare who had been her enemy, her teacher, and one of her best friends. "Green." The word fell from her lips before she realized, and she threw both hooves up to attempt to shove it back in; but it was far too late. "I mean—"

"It's alright, Starlight. I have tied my Shiny up with rope on many occasions. There are some things you have to be very careful of, but I can teach Twilight to bind you up until you can barely squirm." Cadance, with her sense of love and desire, felt the spike in Starlight. "Next please."

"Humping." This one had Twilight blush a little. "It just… it looks like fun when I see a stallion do it. I want some way to feel that… that control over another mare."

"What about stallions?" Cadance's eyes danced. "There are toys for mares to wear, a little harness and shaft, that lets them do just that. But stallions are…" trailing off the word, Cadance let out a happy sigh at the memory, "delightful, too."

"Very Green!" Starlight couldn't believe how honest she was being. Clearly there was a mad gremlin in her head making her say green over and over. Once more, she glanced at her own list and realized that "rope bondage" covered at least two of her own little kinks.

"Control." Twilight continued. "I want to make a pony realize that everything in their life can be given or taken away by me. I want them to beg and whimper for their dinner, I want them to kiss my hooves in thanks for each breath they take."

"Red." Starlight leaned away from Twilight a little. "S-Sorry, but that…" She inhaled a deep breath, finding Cadance's scent to be calming. "That might be too much for me."

"That's okay." Twilight reached a hoof out to Starlight. "Maybe I will need to get more than one pet to play with?" She looked at Cadance while Starlight recovered from her shock at her own negative reaction.

"Starlight," Cadance lifted a hoof gently under the mare's chin. "Would you like to read any we haven't covered already?"

"Drinking… stuff." Starlight tried to hide behind her list to some success. Her voice was soft, so unlike her normal confidence that it was like night and day. "St-Stallion… seed… semen. Mare milk. Fluids from… from…"

"Ohhh…" Twilight trailed off her words in surprise, listening to one of the fetishes she had forgotten, get mentioned. "That is so Green I want…" She shuddered in anticipation. "I would like that a lot!"

Starlight was trapped looking at Twilight. Enemy turned teacher turned friend… turned love interest. She breathed heavy and smiled a little. "What would—"

Twilight felt an urge to act, and leaned forward. She pressed her lips to one of Starlight's ears and whispered very softly. "I will use a spell to make us both lactate. I will milk you until your udders are dry, again and again, and use the milk for breakfast each day. And each morning, your breakfast will be taken directly from my body."

"G-G-Green…" Starlight almost melted in place, and a deep-seated need for submission welled up in her. She bowed her head a little, and all the worries of the world left as she leaned against Twilight and sighed. "Very green…"

The rush of sensation had Cadance grinning happily. Love, lust, and desire bloomed between the two mares and it tickled the Princess of Love every time she saw it. "That will be Starlight's thing, since you are both quite eager for it." Cadance caught two looks of shock. "What, my student?"

"But we need to prepare for that!" Twilight voiced her opinion, running the numbers in her head. "To safely modify a mare's body like that would need us to—"

"I am sure your… honey… will be sufficient." Cadance smiled and booped Twilight on the nose. "As for something else…" With her magic, Cadance levitated her overnight bag to the table and opened it. Lifting out a little barrel device, she saw confusion on both Twilight and Starlight's faces. "This is an udder pump. I do have a filly, you know, and I want to keep my milk up. I think I can spare some for tonight."

Twilight stared at the device, and her mind raced in a hundred directions at once. Copying it, enhancing it, enchanting it, and expanding it. With her heart pounding in her chest, she suddenly realized the interest of Starlight at her side. Her snout pressed to the mare's ear again for secrecy, although Cadance could likely hear her. "You will be hooked up to one of those every night."

A soft groan left Starlight's lips, and without thinking she nuzzled against Twilight. "Is… is this right? Is this safe?" She had trusted Twilight as her teacher, what Cadance had suggested seemed a lot more intimate, but at the same time it was another form of trust. "Will you take care of me?"

Cadance watched Twilight wrap both wings tightly around Starlight and hug the unicorn close to her. "So, ropes and some milking. Perhaps some forced drinking?" Cadance pondered for a scenario to have them play out, then mentally spanked herself. "You will come up with the scenario, Twilight, and I will grade you on it."

"I… I got a book on ropes." Twilight gulped excitedly, quickly able to show she had prepared for such a moment. "There are basic harness patterns in there for mares. I practiced one on myself…"

"Then you will use that one on Starlight. Bonus marks for researching safe games first, Twilight, and more for testing things on yourself. A good domm would never do something to their pet that they themselves could not bear." Cadance claimed both lists—despite them not being fully explored—and rolled them up. "To your bedroom, my student."

Twilight was ready to jump to her hooves and gallop, but remembered there was somepony whose happiness was more important than her own. Lifting a hoof to Starlight, Twilight waited for her new submissive to reach out.

It was the big step, Starlight realized, but she lifted her hoof up and gripped Twilight's. "Your bedroom?" Twilight nodded to her. All the struggle to be the best, and the fight to exert her control over other ponies, sloughed away from her. Starlight took a deep breath as if she tasted freedom for the first time in her life; by giving herself to another.

"Come on, Starry." The nickname was made up on the spot, but Twilight liked it. Connotations of a young mare without full autonomy came to mind, and she trotted off, relying on Starlight to follow.

Cadance watched Starlight gasp and trot off after Twilight. Warmth filled her, and she plucked up the milking machine (and its tubes) and headed after her student. The castle around Cadance felt similar to the Crystal Castle, but emptier. "Twilight is going to need more ponies here, this seems a waste…"

Twilight reached her bedroom and opened the doors. The huge bed the castle seemed insistent that she sleep in now seemed to have more purpose. "On the bed please, Starry." Making her way to her special closet, Twilight used her magic to unfasten the latch inside, and pulled the doors open. Inside were prized possessions, and she had tried all of them. "Let me see… I love wearing this…" Twilight lifted out the tail-raiser.

Starlight watched as her mistress—she almost giggled dizzily at the thought of the word—stepped into a special pair of pants. Her breathing grew heavier, and she had her mouth open and panting as Twilight fastened the odd device on. "Oh…" Shifting her back legs, Starlight felt a sudden heat flush through her body at the sight of Twilight's tail being pulled upwards by the device.

"That is not a common toy for a domm to wear, my student." At Cadance's voice, Twilight spun around, her tail flagging high in the air. "But it looks cute. Where did you get it?" She stepped towards the open closet and admired the budding dominant's collection.

"I got it from a friend… I think it might be Rarity's." Twilight realized she was going to have to talk to her fashionista friend about the device, and maybe more things. "I have plenty of soft, hemp rope. Tree Hugger—"

"I see." Cadance lifted out two ropes and looked to Twilight. When Twilight shook her head, Cadance levitated out a third of them. This time her student nodded. "Very well, show me what you can do, Twilight."

While Starlight watched, both alicorns approached the bed she was laying on. Her eyes kept darting between the pair, but she realized whatever happened, Twilight would do what she wanted and all Starlight could do was tell her to stop.

Twilight watched the indecision in her submissive's attention, and felt a slight pang of betrayal when it settled on her sister-in-law. As Cadance climbed up at the head of the bed, however, Twilight found her own attention focused on the Princess of Love's lower belly.

"Girls, girls, girls…" Cadance adjusted her back legs to leave her two udders exposed. A thin teat was present on each milk-filled sack, and to these Cadance attached the two hoses of the milking machine. The device sensed her body, and activated without warning.

Starlight's warm arousal turned up a notch as the two clear tubes attached to Cadance's teats started to turn white. Soft kachunk sounds were accompanied by Cadance's satisfied little sighs. She barely noticed Twilight's first touch, but when her mistress' hoof parted her back legs she snapped them closed instinctively.

"Starry, are you green?" Twilight didn't need a verbal answer, her blushing submissive opened her legs slowly, exposing her own flat udders and gave easier access to her legs. "Good girl." Using her hooves, Twilight began to wrap the rope, forming the smooth knots that wouldn't dig in and pinch, crossing the rope over and over itself, forming a diamond pattern up her leg.

"S-Sorry, Mistress." Spoken aloud, the word gained special significance for Starlight. She was allowing this. She had given permission for this to happen. "It feels good." She flexed her muscles in the bound leg, finding them strain a little in the grip of the ropes, but not painfully so. While she watched Twilight, her ears were filled with the sounds of the milking machine working on Cadance, while the milked mare loosed an odd whimper now and again.

Cadance couldn't hold still as the machine worked, and her hips rocked slightly; since she had discovered her little… fetish… she had decided that Flurry and future foals would be bottle fed. She watched Twilight work the ropes with her hooves, and Cadance mentally marked a bonus for her student for making it a personal touch.

With both Starlight's legs bound, Twilight brought most of the two ropes up. At last her horn lit, and she lifted her subject from the bed. "I need more access to you, Starry. Your tail will be pinned up, and I have a special surprise at the end." She began to weave diamonds up Starlight's body. Each rope had its place, and as more of the webbing formed she adjusted the tightness to fit Starlight.

Twilight's magic wasn't restricting her, Starlight realized. She could easily twist, kick, and probably even use her own magic to fly away. But of course she did nothing but move her legs as Twilight's hooves pushed them; Starlight Glimmer offered no resistance to the ropes binding her, except to test them in places.

Twilight changed the binding on Starlight's forelegs. Unlike her back ones, the front limbs of her submissive were bound together in the ropes. She watched Starlight's eyes as the unicorn realized this. "With my ropes around you, Starry, you will only move as I wish you to." Twilight stood up straight on two legs, and leaned up to kiss Starlight on the lips.

"Mmmm…" Starlight's eyes fluttered. She was bound, mostly, and she wouldn't be getting away except by magic. As her mistress stole a kiss, she eagerly wanted to press forward into it, but without control over her position she couldn't get any leverage. Twilight's lips broke the kiss earlier than Starlight wanted it, and she let out a little whimper of lost desire.

"I like that sound, Starry." Twilight lifted a hoof to boop Starlight on the nose. "I am going to make sure you can't stop making it." The two ropes that had started on Starlight's back legs were each played out in the knots to bind her forelegs, as Twilight planned. She lifted the last rope and began to tie a bridle out of it.

Starlight's eyes were like saucers as Twilight brought the makeshift bridle up to her face. As it pulled over her features, a little voice in her head said, I am letting her do this, it is great! The only thing she missed was the lack of a bit, or gag, but Starlight was soon distracted from the missing piece as Twilight flipped her around in the air.

"Your bridle is all slip knots, but it won't grip your head any tighter than you pull it." Twilight worked the two spare ends of rope leading from the bridle down Starlight's back, weaving them through the extra loops she had left exactly for this. At Starlight's croup, the ropes diverged. One led to the mare's tail, and Twilight gave a gentle tug on the rope to pull Starlight's head back a bit, and set the tension her dock muscles would be under.

Cadance watched as Twilight bound Starlight's dock in a tightly-woven web of the rope. She saw the shock in Starlight's eyes as she realized where the bridle's rope was connected. "Not too tight, my student."

"Yes, Cadance." Twilight ignored her own lust. She was practically burning with need, but Starlight's had to come first. "The second rope is special." She leaned down and ran her tongue along Starlight's exposed vulva. The taste was rich, tasting like a musky seasoning that made Twilight want to spend all night lapping.

Starlight squealed in surprise at the lick. Somewhere inside rebelled at the intrusion upon what was a very private place, but Starlight had already shed that part of her. She squirmed in the bindings, and when she jerked her head forward her tail pulled up sharply. "Y-Yellow!"

Twilight froze in place. "Are you okay?" She rotated Starlight around so she could look into the mare's face.

"The tail thing… it's too much…" Starlight had to hold her head as far back as she could.

"Would looser be better?" Twilight was already undoing her weave on the mare's dock when Starlight nodded. "Tell me when…" She let a little slack out, and held it while Starlight jerked her head forward.

It was still tugging Starlight's tail, but there was no sharp pain. "I am Green for that." Starlight's voice was, to her shock, brimming with love. "Thank you, Mistress."

While Twilight rewove the dock webbing, Cadance mentally marked down a lot more points for her student.

Twilight took the three free ropes and grinned. "This will be the last part, Starry." One rope came from each of Starlight's back legs, and one from her bridle. Twilight ran the two from her legs up on each side of her swollen vulva. Looping the two ropes through the bridle rope, Twilight started tying knots in them.

Starlight squealed loudly when Twilight laid the knotted ropes along her slit. She whimpered and moaned, and could feel every fiber in the knots rubbing at her sensitive flesh. Her mind felt like mush, and as Starlight twitched one of her back legs, she moaned louder still as the knots moved.

"There." Twilight stared at her masterpiece; each time Starlight squirmed the knots shifted, working away at her folds, kneading them and pressing along her flesh. "Jerk your head for me Starry, just once." She watched as, with the commanded movement, the bridle rope tugged on Starlight's tail, and a carefully placed knot pressed against her winking clit.

Lowered to the bed, Starlight realized she was being allowed to squirm. It was a game, and she was always going to be the "loser," but as if Twilight had control of her limbs, she squirmed. Screaming in pleasure, Starlight couldn't stop once she had started. She kicked, bucked, twisted, and pulled. Each action brought pleasure beyond her imagining. When a particularly sharp jerk ground the knots of the rope firmly along her puffy lips, she couldn't hold back the orgasm that was growing. Shoved expertly into a pleasure feedback loop, Starlight kept squirming as lightning shredded her nerves with pleasure.

Twilight knew what her submissive wanted, though, and even with Starlight screaming the word "green" over and over, Twilight had to think of Starlight's fun first. Laying down on her belly, Twilight aimed her hindquarters at Starlight. The tail-raiser showed its purpose well, and Twilight knew that Starlight would see every bit of her.

The sight shook Starlight's mind free of the crazed grip of the orgasm. Her mistress' vulva was practically dripping, and without reservation she shoved her head forward. Her tail jerked up, and the retreating orgasm was quickly rushed into a second, but Starlight had what she wanted.

It was time for Twilight's own reward. She closed her eyes and relaxed as Starlight literally shoved her snout partway into her. When her submissive pulled back for air, Twilight knew that Starlight Glimmer would now have a soaked muzzle. Then Twilight felt a tongue start on her. The soft flesh parted before Starlight's eager licking, and as each lap cleaned up some moisture of Twilight's, it caused more to be made.

Starlight was deep into a new mindset. She didn't want more pleasure for herself, but her stretching neck and trembling legs ensured she received it anyway. Each time she spotted more moisture beading and dripping from Twilight's nether lips, Starlight licked, and her third orgasm wasn't even upon her before that pattern became a constant thing. She was overwhelmed by how musky her mistress was, the smell filling her nose and mind.

Cadance watched the two mares for a while, even stayed a little after her milker was done. When both ponies seemed completely exhausted, Cadance smiled. "All done, girls." There was no response from either, unsurprisingly. Using her magic, she picked at the knots that were torturing Starlight's vulva, giving her the relief she needed to sleep, and before she forgot she also loosened the strap on Twilight's tail-raiser. "I don't know where you got this toy, Twilight Sparkle, but if you keep using it so much it will have more lasting effects…" Leaving the barrel of her milk behind, Cadance left the two cuddling mares to their sleep.

Author's Notes:

Starlight: You've never really been outmatched or dominated in your life; being in a submissive role will be totally new for you. Nervous?

"I still don't know what... why it feels good." Starlight blushed and gestured to the left with a hoof. "Hey, look at that!" She flew away before any further answers could be squeezed free.
