Running her hands over her legs, Trixie let out a soft moan from her own touch, heightening her arousal slightly. It had been several days since her encounter with Fluttershy, and each evening she had found herself restrained and sexually tortured to the point of exhaustion, Twilight having to carry her to bed on the first night. Although she had predominantly been a rather dominant mare, Trixie had found herself liking the freedom and power she had being removed from her, her body at the sole whims of Twilight Sparkle.

Looking upon the mirror one last time, Trixie gave a nod and collected her clothes from where they sat on the changing room’s small bench, as the mare on the other side waited patiently. “Everything alright in there, darling?” This was the third outfit that Rarity had made, different from the others in that the suspenders for her white stockings were attached to the white corset, which lacked cups to cover her breasts. The fashionista was eager to try out a new range, one that fit Trixie’s purposes as well, and Trixie happily modelled it, but would have to get Twilight’s permission for the photographs to be used. All without panties, on Twilight’s orders. “Trixie?”

“Everything is fine, Miss Rarity, thank you. I still wish you’d let me pay for these clothes. Beauty like this should not be for free.”

“I will hear nothing of it! You have done me a favour, and thus get a reward for the fruits of your labour. Now then, do you remember what I taught you?” Another thing Rarity had been doing was teaching Trixie to walk in her high heels; the mare now known around the town as a secondary library assistant had spotted the alabaster unicorn walking through town in similar shoes with ease, and had thus made her request.

Pushing the changing room curtain aside, Trixie confidently strode out in the aforementioned shoes, barely wobbling and almost floating across the floor. Both mares shared a giggle, before the clock chiming reminded them of the time, Trixie gathering the bags and thanking Rarity for her assistance in the matter, leaving behind Carousel Boutique as she headed home. She didn’t stop to greet other ponies, merely returning their smiles as the sun drifted towards the horizon, the town library coming into view.

Stepping through the door, Trixie gasped when she saw Twilight sat facing the entrance with a cup in her hands, and the way she was dressed. A dark burgundy corset made her ample chest seem bigger, her stocking clad legs crossed over and hiding her crotch, a pair of heels on her feet. Twilight’s mane had been put up into a sort of bun and, coupled with the light that Trixie now noticed was being provided by several candles, made the mare all the more intimidating, not to mention how calm she was as she took a dainty sip of her drink, then set the cup on the coffee table, placing her hands on her knees. “You’re late.”

“Apologies, Miss Sparkle. I was assisting Miss Rarity with a few things.”

“Really? Show me, now.” Putting her bags down and closing the door behind her, Trixie quickly slipped out of her skirt and blouse, revealing one of the sets of Rarity’s new fashion line. “Well? Model it for me, and be sexy.” Trixie took a deep breath and then placed one foot in front of the other, letting her hips move up and down as she calmly walked forward, stopping a few meters from Twilight before turning around, bending over at the waist. The librarian’s eyes started at the floor, going up Trixie’s legs and to her body as the blue furred unicorn stood back up, then turned to face Twilight once more and stood with one hip lower than the other, hand resting on her side as her other arm hung limply towards the floor. “Amazing.”

Trixie’s eyes locked on to Twilight’s almost two sizes too small panties when the librarian stood up and moved closer to Trixie. The lavender unicorn made Trixie shudder as she circled her and ran a finger over the exposed fur, before stepping in front of Trixie, so close their muzzles were almost touching. The lightest gasp for breath escaped Trixie’s mouth as several of Twilight’s fingers entered her seemingly constantly eager pussy. “You little slut, you’re liking this, aren’t you? You like it when I take your body and do what I want with it, don’t you?”

Trixie’s mind was thrown into a tug of war as to how to answer. Some of her prideful and resistant nature remained, fighting against the arousal that was coursing through her body, and she closed her eyes as Twilight pressed into a passionate kiss, Trixie letting the librarian’s tongue in with no resistance at all. She took a deep breath when Twilight pulled away, and opened her eyes to see Twilight was awaiting an answer, one that Trixie now knew, and wouldn’t have it any other way. “Yes, Miss Sparkle.”

“Well, I was hoping your mind wouldn’t be so easy to break, but now it is your body. Turn around, slut.” Trixie did as told, being called a derogatory term such as that making her shiver slightly, even as Twilight roughly pulled her arms behind her back, slipping something over them. Trixie glanced over her shoulder to see a single sleeve wrapped around her limbs, Twilight taking the two straps and crossing them over Trixie’s chest, then buckling them back up at the back. Trixie gave a small whimper as more straps secured the item around her wrists and elbows. Feeling her legs moving, Trixie looked down to see a long metal bar on the floor, with cuffs on each end which were then locked around her ankles. “Now, model for me again, my little whore.”

Taking a shaky step forward, Trixie fought to retain her balance, now more difficult with the wide stance forced upon her, but she made it a few meters before she turned to face Twilight, bending forward once more. She didn’t expect Twilight to be standing right in front of her, hand held at Trixie’s muzzle with a ballgag, but she still opened her mouth and bit down on the rubber, letting Twilight buckle it tightly up behind her head. “Oh dear, my little fuckmare looks a little stuck. How ever will she move around the library now? Come, bitch.”

It was like a whole new Twilight had taken over, her focus seemingly on humiliating Trixie in any way possible. The bound mare swallowed just as Twilight buckled a collar around her neck, attaching a lead to the ring at the front. Trixie was then led towards the stairs, trying to work out how she was going to get up them, but they went past, the mare now noticing the door underneath for the first time. Upon entering the new room, Trixie’s eyes went wide at the various equipment spaced evenly apart. Trixie now knew where Twilight's neverending supply of gags originated, as the back wall was covered with them along with various restraints, but she wasn’t given time to look as Twilight tugged her towards one nasty, but arousing, looking contraption.

Even though it seemed like her body had given in and her lust had won, Trixie still gave a muffled groan and tried to step back, but with the lead pulling her neck down, she had to move where Twilight wanted her to in order to remain upright. “What’s the matter? Don’t you think you’ll enjoy yourself here? By the time I come back, I think you’ll be begging for more, wanting that delicious cunt of yours to take something bigger!” Now she saw the machine up close, Trixie felt her lust take over once more, letting Twilight move her into position.

A single thick pole stood in one corner, with a couple of rubber pads a few feet from the floor, which Trixie was sat upon with her exposed marehood easily accessible. Twilight grabbed a rubber strap and placed it under Trixie’s breasts, buckling it around her and the pole tightly, then removed the bar from the cuffs and bent Trixie’s legs under the supports, the d rings on the cuffs being clipped in place. Trixie watched as Twilight stepped away to a lectern, where several controls were housed, and she followed the wires up to the ceiling and across to where she was sat, a thick black one coming down.

With both pleading and excited eyes, Trixie whimpered something incoherent, drool dripping from the bottom of her gag to her breasts. “Seeing as you fucked with my schedule, I am now going to fuck with you! Hmm, I think I’ll set it to random.” Trixie watched helplessly as Twilight adjusted the controls, then plugged the device in. Almost immediately the dildo on the metal pole below her moved slowly up, entering Trixie’s cunt and making her whimper, before drawing itself back, repeating the process. Looking at Twilight with wide eyes, she realised it was not the dildo moving, it was her, the pole housing some form of mechanism that moved her entire body “Well, I’ll be having a guest soon, so I’m going to leave you here like the fuck toy you are.”

As Twilight was leaving, she glanced over her shoulder at Trixie who began to moan rapidly, the machine now at full speed as the motor sent the mare onto the dildo strong and fast. She then switched the lights off. Trixie strained at her bonds, but wasn’t able to move at all, the machine fucking her was unlike any stallion or mare she had been with before. It would only stop when turned off, and even if her arms weren’t pulled tightly together behind her back, there was no way Trixie could turn it off. Nor did she want to, as the pounding of her pussy reached critical levels, Trixie giving a muffled scream as she came, the rapidly moving shaft prolonging her orgasm.

She found a small respite when the machine went to the opposite extreme, ever so slowly making its way out of her and then back in, Trixie whimpering as the probing toy slid along her sensitive walls. She thought that was it, but let out a muffled moan when it went to about mid range, Trixie trying to close her legs to no avail. The shaft inside her began to vibrate, causing her to go wide eyed as her pleasure sensitive areas were stimulated at the same time, her wall contracting around the dildo as if they were milking a stallion for all of his seed, something that she wished she was having instead as she let out a scream, her orgasm much stronger than the last.

Her hopes that it would slow down once more to give her a chance to rest were not fulfilled as it went back up to full speed, a relentless assault on her love tunnel continuing as her muffled screams and moans drew no rescue. She managed to raise her body a little, the dildo slipping out, but she couldn’t hold the position for much longer, and that was when she realised her mistake. Instead of entering her marehood once more, the pole realigned just further back, Trixie giving a muffled grunt as the rubber phallus forced its way into her tight asshole, something Twilight had only done with her once.

Trixie was surprised to find herself enjoying the feeling, happy that her abused twat was getting some respite, even though her lips and clit still burned from the arousal coming from her unexpected insertion. Her stomach muscles tensed as her teeth dug into the rubber ball, a sudden groan coming from her as she reached a third orgasm, strong enough that her hips began to buck and her fluids released in a torrent to the floor. Taking a few deep breaths, Trixie lifted herself up once more, her leg muscles shuddering as she looked down and realigned herself, settling back down with the dildo once more in her pussy.

With a click the motor went slow once more, Trixie giving a muffled giggle. If this was Twilight’s punishment for her, she couldn’t wait for the reward if she played nice.

Returning to the main room, Twilight smiled when she saw the stallion waiting for her, who instantly smiled himself when he saw how she was dressed. Purposefully walking slowly towards him, Twilight took his hands and pulled him to the couch, letting him sit down. She dropped to her knees and moved her hands to his waist, undoing the buckle on his belt and pulling his pants down, smiling at the shaft pressing against the inside of his boxers, which were soon around his thighs. “Well, Pokey, looks like you’ve been saving up!” The unicorn gave a small groan as she began to massage his larger than usual balls, responding when Twilight slipped her lips around the tip of his cock.

“That’s because you’re worth saving it for, Twilight.” She kept her eyes locked with him as she took his shaft deeper into her mouth, his tip pressing against the back of her throat as her tongue flicked around him. From her lips to his crotch was another two inches, the main reason that Pokey was one of Twilight’s favourites, and her head began to bob up and down. She kept on it for several minutes, then allowing his tip to leave her mouth with an audible pop. “Wow… you took more than usual.”

“Oh, that’s nothing yet.” Taking a few deep breaths, Twilight placed her hands on Pokey’s hips and closed her eyes, shoving her mouth down on his cock. The stallion gasped as he felt his tip go further than before, Twilight’s throat muscles contracting powerfully around his head as her body tried to breath, his eyes wide as her face began to turn a paler shade. When she didn’t pull away, Pokey began to panic and moved quickly, grabbing her shoulders and pulling her from his crotch, holding her up as she coughed violently. Twilight eventually calmed down, opening her tear filled eyes and giving him a sheepish smile. “Guess I need to work on that a bit more, huh?”

“That was dangerous, Twilight. I know we just hook up occasionally, but I still care for you as a friend. Be careful, okay?” She gave him a small nod then moved closer, wrapping one arm around his neck and kissing him passionately, whilst her other hand dropped to his cock, giving it a small squeeze. Pokey pulled away with a chuckle, letting his hands grip her hips and pulling himself against her. “You’re insatiable, you know that?”

“Let’s see if we can stop that then.” Standing up with a smirk, Twilight rolled her tight panties down her legs and stepped out of them, taking Pokey’s hand and standing him up. Because of where his clothes were position, he awkwardly shuffled behind her as she walked towards one of the shelves, then stopped and turned around. “Let’s try something new.” Reaching above her head, Twilight gripped onto the rung of one of the ladders, hoisting herself into the air a little. She placed her feet on the lowest rung and spread her legs, flicking her tail between them and over her marehood, sending the scent of her arousal across Pokey’s muzzle. The stallion didn’t need to be told twice.

He stepped forward and grabbed the stringers, Twilight lifting her legs and wrapping them around his waist, her body dropping so that it took a couple of inches of his cock into her moist slit. Relaxing her arms a little, Twilight’s body slid lower down the rigid shaft, the mare moaning as it did so, before she stopped when she couldn’t take anymore. Tightening his grip on the ladder, Pokey slowly drew back and then slammed back in, eliciting a louder moan from Twilight, then did so again.

Losing her grip, Twilight wrapped one arm around Pokey’s neck and pulled him against her so that she was pressed between him and the ladder with her rump resting on one of the rungs. Her head rolled back with her mouth wide open, heavy, warm breaths blowing past his ear, her breasts squashing against him as her chest heaved heavily. Leaning down, Pokey began to nibble on her neck, eliciting a deep moan from Twilight, who squeezed her legs tighter around his waist.

Being pretty aroused from Trixie’s little show, and the knowledge of where she was now, the gap between Twilight’s moans was getting smaller and smaller, Pokey giving a small groan as he increased his thrusting speed against her tightening walls. Their lips met in a passionate kiss, tongues wrestling for control until Twilight pulled away with a scream, her limbs tensing and pulling Pokey close against her body with her walls clenching firmly down on his shaft. He didn’t last much longer, hilting inside of her with a deep groan and sending wave after wave of hot spunk into the softly moaning mare.

Once their bodies relaxed, the pair climbed back down to the floor, where Pokey took Twilight’s hand to help keep her steady in her heels, and she flashed him an appreciative smile as he slipped his pants back up. “Thank you, Pokey. Say, would you like to see my new toy?”

“Sure.” Keeping her hand in his, she led him over to the door under the stairs, a room he had not seen as of yet and did not know what was in it, but when the wooden barrier was opened his ears twitched at the small whimpers. He decided not to say anything for the moment, as he couldn’t see what was going on. Then the lights snapped on and he gave a chuckle; he had seen the mare that was bound and gagged around town and going into the library every now and then, but didn’t know why. “Well, Twilight, I think your toy might be exhausted.”

Trixie then showed signs of life, whimpering as she lifted her head to look at them. Her mane was hanging limply around her face, her blue fur matted with sweat, and her body still moving up and down on the didlo. Twilight slowly walked over and took Trixie’s nipple piercings in her fingers, giving them a small tug and making Trixie give a shriek, eyes going wide as she looked at Twilight. “Oh good, you are awake. Trixie, say hello to my good friend Pokey.”

“Hellpho, Popheyph.”

“Good filly, do you want to come out now?”

“Yeph pleaph, Mipph Sparphle.” Lighting her horn, Twilight shut the machine off, Trixie’s body slowly coming to a stop with the didlo out of her, and Twilight started to unbuckle her from the pole. Once able to stand, Trixie instead knelt to the floor as her legs felt like jelly, and she took a big gasp of breath as Twilight removed the ballgag. “T-thank you, M-miss Sparkle.”

“You are most welcome. Can you walk?”

“I… I don’t think so, Miss Sparkle, not in these shoes.” There was a small moan from the bound mare as her feet were freed from the high heels, then she felt hands firmly massaging them. Her weight was then taken, and she looked around wearily to see it wasn’t Twilight holding her, it was the stallion. “T-thank you, sir.”

“Twilight?”

“I’m teaching her manners as well. She was being punished for being late. Come on, I’ll show you to her room.” Holding the mare firmly, Pokey followed Twilight to the first floor of the library and into one of the spare rooms, then laid Trixie down upon the bed that the librarian indicated. Twilight walked over and rolled Trixie over, unbuckling and unzipping the armbinder, Trixie’s arms falling to her sides limply. “It seems I am going to have to help her. You don’t mind, do you, Pokey?”

“No, not at all. I’ll see you later.” He leaned in close and kissed Twilight on the cheek, making her give a small giggle, and she continued to undress Trixie as he left. From there, she helped the exhausted mare into the shower, the warm water and firm massage bringing life back into Trixie’s numb limbs, sending her even closer to slumber. Once they left the bathroom, Twilight kept walking with Trixie’s hand held tightly, leading her into the master bedroom.

“You did well to last that long, Trixie. Tonight, you get a reward.” Pulling out a paper bag from under her bed, Twilight pulled out a nightie, a light sheer blue except around the breasts, and it was only just see through, several stars lying on each cup. “Come, let’s get you to bed.” Trixie moved, but Twilight still had to help her into the garment, and stopped her from returning to her own room. “No, Trixie, you’re in here tonight.”

“B-but Miss Sparkle, what about you?”

“Oh, I’ll be here as well.” Twilight pulled out another nightie, the same in style but light purple in colour, with blue moon and wand on the cups. Once she was wearing it, she took Trixie’s hand and pulled her to bed, where they wiggled under the covers, Trixie unmoving as her brain tried to understand what was happening. “Trixie, if you want me to stop this, then please just say so. We can go back to just normal lessons if you want to.”

“Twil… Miss Spark...” A hand on her muzzle silenced her, and she turned to see Twilight shaking her head.

“I am only ‘Miss Sparkle’ or ‘Mistress’ when the collar is on, Twilight when not.” Trixie reached a hand up to her neck, frowning as she felt it collar free for the first time in days, excluding when she was getting washed. “So, what do you want to say?”

“I… I would like this to continue, Twilight, but there is one thing even you can not give me, whether reward or punishment.” Twilight sat up and gave Trixie her full attention, and gave her a nod. “I… I want cock, Twilight! It has been so long since I was with a stallion! Please, as my reward, let a stallion use me?”

“Hmm… I think… I think we can use this both ways. If that is your terms, allow me to lay my own. If you are naughty, then your punishment shall be watching a stallion… rut me instead. What do you say?”

“Seal it with a kiss?” Twilight giggled at the mischievous twinkle in Trixie’s eyes, leaning down and softly pressing their lips together. Lying back down next to Trixie, Twilight moved her arms and pulled her into a close embrace, Trixie returning the hug. “Twilight… for what I’ve done… I’m sorry.”

“I forgive you, Trixie. But we still have to knock your sense of pride out of you, don’t we?”

“Trixie will meet your challenge and beat it!” The pair stared at each other unblinking for a moment then descending into a fit of giggles, before finally lying still and closing their eyes. Trixie drifted off into a deep slumber whilst Twilight lay dozing a little while longer, her ear twitching when she heard the library door open. It was followed by two sets of feet on the staircase, slowly approaching her door.

“Okay, we need to be quiet here, I’m not sure how Twi would react to me bringing a filly home.”

“I’m sure it’d be fine, Spike.” A smirk crossed Twilight’s muzzle; she knew he had been getting more friendly with the fillies in town, and one unicorn in particular. Perhaps a talk with Derpy would be needed, just to be on the safe side.

Author's Note

Okay, so in light of the age rule for anthro/human stories and the age for any mature stuff being brought to my attention, there will be NO mature scenes between Spike and Dinky. All plans for this to happen have been scrapped. We may see some interaction between these two, but nothing explicit.

Anyway, the biggest complaint I received, even with the AU tag, has now been addressed. Trixie has apologised to Twilight.

But she's not given in fully as of yet, there's going to be a lot more training along the way!
