Chest heaving as she panted around the gag, Trixie had lost count of how many times she had cum, nor had any idea of how much time had actually passed. Her arms ached from the position in which they were held, her jaw was sore, and her nethers were burning. Thankfully, the machine had shut itself off after a while, most likely to prevent it from burning out. “Twiligpphh?”

Once more her plea went unanswered, much as it had been all morning, her body completely exhausted. The light suddenly flicked on, Trixie turning her exhausted eyes to the stairs. “Twilight, are you down there?” Trixie could only whimper softly, hoping to get the attention of the soft speaking mare at the top of the stairs, if only for some loosening to the restraints. “Hello? Is somepony down there?”

Upon hearing footsteps on the wood, Trixie felt a wave of relief wash over her when the petite form of Fluttershy drifted into view, the pegasus giving a startled shriek as she saw the bound and exhausted unicorn mare. “Oh, Twilight, I’ve told you not to leave them all morning. This won’t do, this won’t do at all.” Walking over, Fluttershy unbound Trixie to the point where just her gloves and gag remained, and the unicorn glanced over her shoulder to see Fluttershy had stopped. “Oh, I’m not letting you out. Twilight must have had a reason to do this.”

Trixie thought the mare was betraying that statement as she began to slip the gloves down, but then saw the length of rope that Fluttershy was holding. Once her upper arms were free, the pegasus wasted no time in wrapping the rope around Trixie’s elbows, pulling her arms close behind her back and tying it off, making the unicorn give a muffled groan. “Oh dear, you’re covered in sweat. Come, let’s sort this out.”

Fluttershy removed the gloves fully, followed by the stockings, and slipped a finger around the string attached to Trixie’s piercings, forcing her to follow as she walked away. Once up in the main room, Trixie whimpered when she saw it had gone past lunch time, meaning she had been in the basement for a good five hours, and really felt it when her stomach grumbled, but Fluttershy just let out a small giggle. “Oh, we’ll sort that out, but not until you’re clean.”

Leading Trixie upstairs, Fluttershy took her into the bathroom, where she used another piece of rope to tie the one around Trixie’s elbows to a pipe running above, then stepped back. All Tirixe could do was whimper happily as the warm downpour started, the soothing flow bringing life back into her limbs once more as she closed her eyes. “Now don’t go anywhere,” the pegasus giggled, “I’ll be right back.”

It was a several minutes later when she opened them, having felt hands running over her fur, to find Fluttershy in just her underwear in the shower as well, a bottle of shower gel held in her mouth. The pegasus then began rubbing it into the unicorn’s fur, whose eyes closed once more at the gentle touch. Too soon the shower ended; Fluttershy helped Trixie out and into the spare room, then rubbed her down with a towel. Reaching her hand up, Fluttershy unbuckled the gag, Trixie taking a deep gasp of breath as she worked her sore jaw, then looked happily at the pegasus. “Oh, thank y…”

“Ah, no talking!” Trixie let out a yelp as she felt a hand firmly slap her ass, and she bit her lip as the drying continued, at which point her arms were finally released from their bonds and the kind pegasus removed the string from her piercings at last. Looking to the side, she spotted a plate piled with food and a large glass of water, then back to Fluttershy. The pegasus had barely nodded when the unicorn shot forward, eagerly sating her hunger, so she walked towards the closet. “Now then, what should we go with?”

Trixie ignored the question as she gulped down the drink, bringing relief to her parched throat and turned to thank Fluttershy. Instead, her eyes went wide at the outfit now laid out on the side; but she had to admit, there was a certain allure to wearing such items. Having noticed Trixie had finished eating, Fluttershy grabbed the unicorn’s hand and pulled her over, standing her in front of a large mirror. “Arms up, please.”

Doing as instructed, Trixie just watched in silence as a black corset was slid over her chest, rigid cups to hide her breasts, and it was pulled taught at her back. “Breath out.” Once her stomach was naturally flat, Trixie felt the laces at the back being pulled even tighter as Fluttershy started to tie them up. Even though she could do the rest without assistance, having another forcibly dress her was another power play that Trixie willingly gave into as Fluttershy crouched down and lifted Trixie’s legs one at a time, then stood back up.

Trixie felt a piece of fabric following, then glanced down to see a small back patch over her nethers, with almost a string wrapping around her waist and under her tail, where it met the one running through her crotch. Following the arm on her shoulder gently pulling her back, Trixie sat on the edge of the bed as Fluttershy slowly rolled stockings up her legs, followed by sticking a pair of black, six inch heels on her feet. Standing up, Trixie wobbled a moment before regaining her balance, then crouched down as Fluttershy slipped a choker around her neck, slipped on a pair of opera gloves onto Trixie’s arms, then motioned towards the mirror.

Trixie was stunned. Reflecting back at her was a mare whose muzzle showed clear amazement that she could look so good with so little on, and she went to run her hands over her body, but was stopped as Fluttershy grabbed her arms. “Oh no, I said I wasn’t releasing you, and I meant it!” With dexterity expected of most pegasi, but not the one currently in the library, Trixie’s wrists were tied tightly behind her back, and she was about to either protest or plead when a gag was once more shoved into her muzzle.

This one was different, Trixie could feel a metal ring behind her teeth, but she could move her tongue unlike with the ballgag, and she let out a small whimper as Fluttershy used another rope to secure her elbows once more. Turning around, Trixie saw that the pegasus had gathered more ropes when she was looking in the mirror, and Fluttershy grabbed a longer one before stepping behind the unicorn. Wrapping it under her breasts and arms, Fluttershy threaded it around twice before pulling it between itself, then sent it to Trixie’s chest once more, above her breasts this time.

Trixie continued to watch, curious as to how this quiet, shy, reserved mare knew how to tie her up so securely, yet in such way that the ropes were not hurting. She gave a small moan as the ropes around her chest were pulled tight. Then Fluttershy pulled it over her shoulder, looped it intricately around all the ropes over her cleavage then over Trixie’s other shoulder. Pulling it tight caused the ropes around Trixie’s chest to compress together over her cleavage, and Fluttershy tied it off at the back, where Trixie could feel more hanging down. “Now, as you’ve been a good filly, I think you should get a reward as well.”

As she glanced down to see what Fluttershy was strapping to her waist, Trixie began drooling, covering her breasts in an unstoppable torrent of saliva. Stepping in front of Trixie, Fluttershy reached between her legs and pulled the rope through, then firmly upwards, Trixie’s eyes shooting wide. Fluttershy ignored this as she wrapped it round Trixie’s waist, tying it tightly off at the front. Stepping back, Fluttershy held up a small pink box with a long cable, clicking a switch, Trixie moaning as she felt small vibrations against her sensitive pussy, the toy held tightly in place by the taut rope. “Come on then, don’t keep me waiting.”

Walking towards the bed, Fluttershy pulled the control and Trixie with her, before she sat down on the edge of the mattress, then slid a hand down and pushed her pink panties to her ankles, kicking them away and tugging Trixie closer as she spread her legs. “Well?” Trixie gave Fluttershy a confused stare, and the pegasus just rolled her eyes as she sat up and grabbed Trixie’s horn. “Tongue, now.”

Being pulled forward as Fluttershy fell back led to Trixie burying her muzzle between the butter yellow thighs, still damp from joining Trixie in the shower, where the scent of arousal hit her nose, and she slipped her tongue out slowly, then groaned as the sweet nectar of the mare graced her taste buds. Now knowing what was expected of her, Trixie leaned further in so that her lips were pressed against Fluttershy’s lower set, her tongue slipping into the moist entrance and swirling around the walls.

On the mattress, Fluttershy was beginning to pant heavily, not having had attention from anypony else for awhile, her cheeks flushed as she ran a hand through Trixie’s mane, both to have something else to focus on and to keep the unicorn in place. Soon small, adorable moans sounded from her throat as Trixie somehow pushed her tongue deeper, sending shivers up the pegasus’ spine. In reward for her efforts, Trixie moaned happily as the vibrations increased against her crotch, and she pulled the rope keeping it there in place.

Her ears flicked as a sudden noise distracted her, and she pulled away from Fluttershy, who sat up as Trixie turned to face to door. At first they thought it was a customer, as they could hear them walking around the main floor, but then came the footsteps on the stairs. The door had been left open, allowing a rather agitated Twilight Sparkle to look into the room, but her expression soon changed when she saw the mare breathing heavily on the bed and the state she was in. “Fluttershy, why didn’t you say anything?”

“I… was… afraid… you’d say… no.” Calming down a little, Twilight walked over and glanced at Trixie, who averted her gaze to the floor. Tilting her muzzle back up, Twilight pressed into a deep kiss, sending her tongue through the ring and forcing Trixie’s to move out of the way, the librarian giving a happy hum when she pulled away. “I’m… sorry, Twilight. I’ll just… go.”

“No, Fluttershy, if you need release, I’m sure Trixie will be glad to help. Won’t you?” Looking up, the former showmare saw Twilight now had a crop in her hand, and brushed it over Trixie’s muzzle. “Look at her and tell me you want to help her.” She did as instructed, letting her gaze roam over the form of the panting pegasus, then back to Twilight.

“I waphh topp helpphh herpph, Miphh Sparphhlepphh.” Twilight nodded, pushing Trixie back into position, and the mare returned her tongue to its duties. Her vision was removed as Twilight slipped a blindfold over Trixie’s eyes, then the bound mare let out a yelp as the crop slammed against her ass, followed by a whimper.

“No noise, or it’ll get harder.” Trixie did her best, remained with her tongue at work as Twilight’s crop stung her cheeks more times than she could count, and she was beginning to enjoy it when the thrashes stopped. “What do you think, Fluttershy, should we change her gag?”

“Oh… my. It’s, um… big.”

“I have smaller if you want me to chan…”

“No… I’ll, um... take it.” Trixie took the chance to gasp for breath as she was pulled up, internally joyful as she felt the buckle of the gag become undone, but as before it was replaced. This time, along with a larger ball, it was accompanied by straps that kept her muzzle tightly shut, as well as making her head drop from a large weight on the end. “Trixie… move… forward.” She did as Fluttershy instructed, but felt resistance much earlier than before. Whatever was on the other end of the gag was moved around, and the unicorn found herself shift again.

It wasn’t until she felt the fur on her nose that she knew what she was now wearing, drawing her head back a little and thrusting it forwards, earning a rather loud moan from the pegasus that encouraged Trixie to keep doing it, thrusting the dildo on the end of her gag in and out of Fluttershy. She was well aware that whilst doing this Twilight has undone the rope from her waist, removed both the vibrator and her thong, and was now doing something behind her.

It wasn’t until she felt something cold and hard press against her own dripping pussy that she knew what was going on, giving a very muffled moan as Twilight pushed deeper, until the fur of Trixie’s crotch met with her own. Outside of the blindfold, Twilight reached up to take Fluttershy’s hand and pulled her into a sitting position, their lips meeting in a passionate kiss as they moaned into each other’s mouth. Twilight slowly shifting her crotch back and forth from Trixie’s.

Only once the two free mares pulled away, panting for breath, did Twilight increase her thrusts, the strap on buried deep in Trixie now shifting further in and out, the librarian smirking as her assistant’s body shuddered from the pleasure. With every fast and powerful thrust Twilight made, Trixie was forced back and forth harder against Fluttershy, whose screams of passion would rival that of a young newlywed couple on the first night of their honeymoon. Trixie herself was near the same level, but her sounds of arousal were doubly muffled, and even with the blindfold her eyes were still scrunched shut.

She gave a small whimper when she felt Twilight pull out, not having reached her release, which turned into a muffled scream when the now lubed up shaft pressed against a much tighter hole, the tip pressing in. “Don’t resist me now, it’ll hurt otherwise.” Otherwise? It’s hurting now… but I like it! In order to show how obedient she was being, Trixie spread her legs wide, giving Twilight the access she needed to enter. “That’s a good filly. Don’t worry, I haven’t forgotten about this down here.”

The pleasure that had been removed from her pussy returned as she felt fingers easing their way in, and then felt pressure on her clit. Taking a few moments to let Trixie get used to the shaft deep within her ass, Twilight leaned forward and took one of the bound mare’s ears in her teeth, giving a gentle nibble and causing Trixie to let out a happy moan. She then started to shift back and forth, Twilight ensuring to keep her fingers working at Trixie’s dripping love tunnel as she rammed into her ass.

Twilight smirked when she looked at Trixie’s arms, seeing the limbs straining at the bonds holding, as her hands clenched and unclenched rapidly, before her fingers shot out wide as a muffled scream of passion echoed from between Fluttershy’s thighs, Twilight pulling her hand away to find it now soaked by Trixie’s freely flowing juices. The bound mare gave a whimper as she was pulled from the pegasus, blinking rapidly as the blindfold was removed and light flooded her eyes, Trixie looked up to find a furious Twilight returning her gaze. “You dare finish before our guest?”

All that escaped the mare was a muffled whimper as she tried to apologise, but the librarian just turned away, Trixie watching as she slid open a drawer and rummaged around in it. Whatever dangled from the lavender mare’s hand did not look too inviting, so Trixie tried to move back in, but with her gaze centred in one place she hadn’t noticed Fluttershy had moved, the pegasus pressing her hands down on the unicorn’s shoulders to keep them in place. Trixie gave a small groan as Twilight pulled the cups to reveal Trixie’s breasts, the showmare watching with wide eyes as the first metal jaw closed above and below her nipple, squeezing the nub tightly, and then Twilight clamped the other teat.

Trixie panted as a new pain ran through her body, panting heavily as Twilight hooked a finger around the chain connecting the clamps and gave it a tug, increasing the grip as she pulled them further away. Twilight then let the chain drop, Trixie giving a whimper as Fluttershy laid back on the bed and spread her legs. “Well? My guest isn’t satisfied. Get to it!” Trixie immediately moved over, and now she could see what she was doing, easily slid the dildo back into Fluttershy’s glistening honey pot. The unicorn eagerly shifted her head back and forth, but she still gave a muffled yelp as the crop once more struck her ass cheeks, much harder this time. Trixie kept her noises to a minimum though, remembering Twilight’s earlier instruction.

Her ears twitched as Fluttershy’s moans grew to quiet screams, the pegasus’ legs moving closer around Trixie’s head, making it hard to move, and the thrashes continued. The sounds of arousal grew louder, Fluttershy suddenly grabbing Trixie’s mane and forcing her head as deep as possible, letting out a loud scream of passion as her thighs squeezed Trixie’s head. After a few moments the pegasus fell to the mattress with an airy sigh, Trixie being released from the surprisingly strong legs, but she wasn’t allowed much respite as Twilight pulled her to her feet. “I’ll be downstairs when you’re ready, Fluttershy. And you,” Trixie briefly glanced at Twilight, then to the floor after seeing the librarian still looked angry. “I don’t think there’ll be much more today. Time to get back to work, but you’ll remain wearing that outfit. Understood?”

Trixie gave a nod, Twilight stepping closer and putting a hand behind Trixie’s head, unbuckling the gag, the mare taking a deep breath before her mouth became occupied by Twilight’s, who happily hummed as her tongue slipped in. Trixie desperately wanted to return the embrace being given her, but could barely move her arms. She gave a small whimper as Twilight pulled away and left the room, then felt hands at her wrists, glancing over her shoulder to see Fluttershy behind her, and the pegasus began to untie the unicorn. Several minutes later and three pieces of rope were on the floor, Trixie slowly reaching to her breasts, taking a deep breath as she eased the pressure on her nipples, letting out a loud groan as the clamps came off, dropping them to the floor and rubbing the sensitive areas.

As she left the room, Trixie was grateful to see a skirt and blouse on the railings, quickly slipping into them and holding on to the bannister as she made her way down the stairs, followed by wobbly walking towards the kitchen, where she could hear stuff being moved around. Glad she had found Twilight, Trixie stepped towards the table and took a seat. “Miss Sparkle, might I make a request?” Twilight turned from the cabinet she was busy with, looking at Trixie with a raised eyebrow then gave her a nod. “Could I… possibly remove these shoes? They are a little too much.”

“Yes, I can see that. Very well, you may go change them.” Standing back up, Trixie made her way slowly back upstairs, stepping into her room and opening her closet. Rarity had generously made her several outfits, as well as matching shoes, and Trixie slipped her current pair off before crouching down to her collection. Choosing a similar style, but with half the height, Trixie now found it easier to move around, heading back to the main floor, walking over to the book returns as Twilight walked out of the kitchen. “I shall be busy with studying this afternoon, Trixie, so once you are done, you are free to finish.

“Thank you, Miss Sparkle.” Even after what she had just been through, Trixie hummed happily as she began to return the tomes to their respective places, something she had actually began to enjoy. Even though he was Twilight’s number one assistant, Trixie knew Spike, the young teenage dragon, was grateful for the help she provided, letting him take the time to go explore his adolescence. Both mares ignored the door as it swung open, only turning as something thudded to the floor, to find Spike staring dumbly at Trixie as a small statue near the entrance rolled around on the floor. Even with how brash as she usually was, Trixie couldn’t help but turn away from the dragon with a blush on her cheeks, which only intensified when he spoke.

“Damn… those legs.” He turned around to find Twilight sitting in one of the alcoves, having cleared her throat to get his attention, and was now glaring at him. She had caught the drake staring at Trixie quite a few times, and she couldn’t mistake what he must have been thinking; he was at that age, after all, where he was ruled more by hormones than thought, more so as he approached sixteen, even though he had good control. “Oh... hey, Twilight.”

Quickly bending down, Spike picked the statue up and put in back on the table, closing the door behind him. He then quickly made his way upstairs, the two mares sharing a small giggle at his rosen cheeks as he passed, but he stopped when he glanced into the spare room. Fluttershy was still on the bed, chest heaving as she still rested from her encounter with the showmare, and the dragon then noticed the other items strewn around the floor.

.Knowing Twilight’s preferences, he easily worked out what had transpired, picking up the gag and giving a sniff of the juices coating the dildo on the end, then obeying his body’s commands to lick the arousing scent, giving a quiet groan as the sweet taste graced his tongue. Fluttershy began to stir, so he quickly dropped the gag and left the room, slamming his door shut. His pants were now tight at the crotch, so he slowly stepped forward and lifted his mattress up, grabbing the small pile of photos he had stashed there.

Having ‘borrowed’ one of Twilight’s magazines where she ordered stuff, Spike and his marefriend had purchased some things for themselves after combining their bits together, even if neither Twilight nor Derpy would approve; the photo he had selected held the form of his marefriend staring back at him from her bed, eyes sparkling with arousal, wearing only light blue stockings and suspenders. He knew Dinky would be poking her tongue out at him were it not for the bright pink ballgag, the black strap running around her head and clashing light violet coat. Her arms were locked in cuffs behind her back, whilst her legs were spread wide by a long metal bar, her marehood on full display.

Closing his eyes, Spike imagined joining her, letting his hands move on their own accord as if they belonged to the pretty, young, and supple unicorn mare.
