Author's Note

This story is an unofficial chapter to Gloryshy by Anonymous Pegasus. I got the idea to write this because it felt like there should've been more to the story. It's also given me the chance to do a shipping I haven't seen anywhere else before - Flutter Burst.

EDIT (12/13/2020) - Noticed some spelling mistakes on a reread and came back in to fix them. Don't be afraid to message if there's anymore I missed.

Act 4: Sunburst

Fluttershy looked left and right before sneaking back behind the bath house to the maintenance room. It had been three months since her last visit here. She had wanted to come back much sooner, but she had been scared for a number of reasons, one being that rumors were spreading among stallions about who the mare was that was pleasing the patrons of the bath house and her name had been mentioned, though it was fortunately dismissed rather quickly. The actual reason, however, was much scarier for her, and any mare in Equestria for that matter.

During her last visit, she had been enjoying her working of giving the stallions in the bath house some much needed sexual relief by use of her mouth. But, when she discovered a second hole behind a panel behind the one she had been using, she had allowed the unthinkable, at least for herself, to happen. She had taken a stallion's penis inside her vagina, and had sex with him until he shot a full load of his cum into her. She could still remember the warm sensation spreading through her, as well as the hard shaft struggling against her as it pumped its contents inside her. In the moment, it was blissful and amazing.

On her way home, however, that bliss turned into panic. She had no idea where she was at with her cycle. She honestly had no need, as she had never engaged in sexual activities before, and didn't really worry about it when she had begun visiting the bath house. After all, it has been proven scientifically impossible, as Twilight would say, for a mare to become pregnant from ingesting a stallion's sperm. But, it was all too possible when that same sperm was plastered against the entrance to a fertile mare's womb.

Quicker than she could ever remember herself being, Fluttershy flew to the only pony she knew could help her with her potential problem: Zecora. The zebra mare was rather shocked by the assertiveness of the usually timid mare, so much that she actually broke from her typical speech pattern of rhyming. After swearing her to total secrecy, Fluttershy relayed her problem to the zebra and asked her for whatever help she could.

Fortunately, Zecora was able to help her, and produced a potion that would prevent the seed from planting in her womb for a period of one week. After that, the zebra recommended coming back and getting a regular supply of contraceptive potion that she brewed, lest she decide to engage in such risky activities in the future.

Now, Fluttershy was back at the bath house. This time, she had come prepared. She took a glass vial of purple colored liquid from her saddle bags and knocked it back. It had a disgusting flavor to it like all other medicine, but that was a minor inconvenience for its desired effect: Rendering a stallion's seed useless. The way Zecora explained it, the sperm and potion would congeal in her womb, and then would be expelled harmlessly out of her body. At this, Zecora recommended that Fluttershy find a place to void herself soon after, as once she had exited her aroused state, her body would expel it quickly.

Tossing the empty bottle into an empty pouch in her saddlebags, Fluttershy quickly snuck inside and closed the door. Calming herself, she turned around and faced the room full of water heaters and spare parts. Making her way past them, she had found the door to the cubby hole that had became her personal sanctuary. Slipping inside it, she quickly opened the wood panels and peered out into the room.

There was not a single stallion seated inside the bath house! Her jaw dropped in shock; Fluttershy thought that there were always stallions here! Why weren't there any now? She began to get flustered, as she had been looking forward to finally coming back to this place, now that she was fully prepared for any potential consequences. She also wondered what would happen if she didn't mate with a stallion before she lost her aroused state after taking the potion, and a little upset that it could potentially be a waste of a hefty sum of bits. It had taken her nearly three months to save enough for the dozen bottles Zecora had given her.

Just as she was about to give up, she heard a set of hooves enter the room. Holding her breath, she searched for the pony who walked in, and then he came into her field of view. She recognized him almost immediately. He had cornflower blue eyes, gamboge fur with light gray socked hooves, and a vermillion mane. Despite the lack of cloak and glasses, she knew it was Sunburst.

Upon seeing him, Fluttershy's heart skipped a beat. She would never admit it, but she actually had a crush on the stallion. She thought his eyes were very pretty, and his facial hair was befitting him. She also admired how knowledgeable he was about magic, even if he wasn't the greatest at casting it. The thing that made her crush on him the the hardest was the way he had with foals. He had a very good way with them; Soft most of the time, but firm when necessary.

As she stood and admired the stallion, she subconsciously brought a forehoof between her legs and began teasing her nethers, feeling them become wet with her arousal. Seeing Sunburst brought back a fantasy, though not one of a sexual nature. In it, Fluttershy and Sunburst were together as a couple, and had a pair of foals, a pegasus filly and unicorn colt, and were a happy family. She knew that she would one day want a family, and that of all the stallions in Equestria, he was the one she wanted to have it with.

Her desire was beginning to overwhelm her, and she was almost ready to signal for his attention, but she stopped herself. Was she okay with her first time with Sunburst to be this way? Anonymously and through a wall? Her winking nethers were beginning to squash her resistance. The justification soon came afterward; If she wanted to one day be involved with the stallion, wouldn't it be good to get the question of sexual chemistry out of the way first?

She tapped her hoof three times on the edge of the hole and then turned herself around, pushing her eager sex to the cavity, remembering how the last stallion had trouble getting all the way inside. Inside the bath house, Sunburst heard the knocking and looked around for a few seconds before his eyes befell a sight he hadn't expected to see. Inside of a circular hole in the massage bench, was a mare's labia, wet with arousal and winking every so often.

Fluttershy held herself steady as she heard the stallion slowly approach the wooden box. Part of her questioned whether or not this was a good idea and if she should back out before it's too late. However, the hood steps stopped as they sounded close to her. There was nothing for a few moments, before she heard the stallion speak to her.

,"M-M-Ma'am", he stuttered, clearly nervous,"A-A-Are you a-actually o-o-offering?" Fluttershy blushed, surprised by his timidness and embarrassed that he was addressing her as ma'am. She needed to respond, so she made the loudest "mhm" sound her timid nature and nervous body would allow. After that, there was silence for a few moments, and then a rather unusual sensation for the mare; a few puffs of hot air, then something soft, yet strong, and wet, was lightly tracing at her outer folds. She gasped as she realized that it was a tongue, and Sunburst was giving her oral pleasure.

Sunburst had knelt down in front of the hole and proceeded to examine, and then lick at the hole inside that one. The mare tasted sweeter than most, but had a muskiness to her that made him think of various animals he had encountered before. A thought that the mare he was tasting was the resident animal caretaker named Fluttershy crossed his brain, but was quickly dismissed; While this would be a way to help her overcome her shy demeanor, or at least scratch the itch of estrus, he didn't see the shy mare as one to partake in such activities.

Fluttershy held her breath as Sunburst went about lapping at her nethers. She cooed softly with each pass of his tongue along the outer lips of her sex, and a gasp when the tip grazed at her sensitive clit. She had never considered a stallion giving her oral pleasure before, and while she wanted to tell him that his actions weren't necessary, she didn't want to risk being discovered. Feeling broader strokes of his tongue and quicker pace, a hoof in her mouth was all she could do to stifle the moans threatening to be ripped from her throat.

Sunburst could hear the mare moaning at his ministrations on her quim. He was happy to hear it and worked more eagerly to elicit more noise from his anonymous partner. Truth be told, Sunburst had been with a few mares already, and he found he enjoyed being with them more if they got as much out of sex as he did. That's why he worked as hard as he did with his mouth on mares; It made his own pleasure he would experience later feel as though he had earned it.

The two ponies began to settle into a rhythm, as Sunburst continued lick at Fluttershy, and the mare began pushing back into his tongue. The stallion took this as a sign to step up his treatment. Fluttershy was enjoying his ministrations when she felt the strong, wet appendage begin to dig inside her, letting out a moan as it explored deeper into her and brush up against a few miscellaneous sensitive spots. Sunburst heard the moan and dug a little deeper and harder, wanting the mare he was pleasuring to go to the moon and back from pure orgasmic bliss.

Fluttershy fought to keep her composure and keep quiet, but it was a losing battle. Sunburst knew how to use his tongue. It was a fight she had no chance of winning. A pressure was beginning to fester in her loins, and with each stroke of his tongue tip against her sensitive walls, it threatened to push her into a wave of orgasmic bliss that could very well knock her unconscious.

Sunburst could feel her velvety soft tunnel begin to clamp on his tongue tighter and tighter. Combined with the barely audible moans he could hear coming from within the hole, he knew that this mare was well on her way to nirvana. Well, who was he to keep her waiting? Motivated to push her to that veritable edge, he dove his tongue in as deep as he could and lapped at her vaginal juices.

The pegasus was already in a world of bliss, but was sent to new heights when she felt the tongue press as deep as it could reach, and could swear she felt his lips sucking on her outer folds as though he were drinking in her arousal. The pressure was starting to reach a fever pitch, and she did all she could to fight against the tide. In the end, it was all for naught. Spurred on by the stallion's eager actions, Fluttershy forced a hoof into her mouth and let loose the best orgasm in her life.

Sunburst felt the mare tense and a series of very strong contractions grab onto his tongue and prevent him from withdrawing from the mare. He heard a moan that was quiet but still more audible than the others, and felt a rush of mare juice fill his mouth. He greedily drank it down, manipulating his lower jaw so his chin strap facial hair teased her clit and gave her a little extra stimulation.

Fluttershy shook in place as she came, never believing in a million years that a stallion would want to "eat her muff out" as Rarity had commented rather lewdly once during one of their spa sessions. The feeling of his warm tongue was amazing on her outer and inner folds, and his eagerness to bring her to release was something she was very grateful to have experienced. But, the oral treatment she had just received was only a precursor to what she had truly come here for. She was going to have to properly thank him once she had caught her breath.

Sunburst moved back from the hole, satisfied that the mystery mare was satisfied. Truth be told, it was the part about sex he found the most fulfilling. It made him feel good deep down inside that his partners could receive such joy from him. He waited patiently for his partner to recover her bearings, not daring to enter without a clear invitation to do so.

Fluttershy finally got her breathing and quivering under control. The orgasm she just felt had been one of the best in her whole life, but it was still outdone by one: The time three months ago when a stallion actually had sex with her. She couldn't get over the feeling of fullness his length had given her, and then the waves of hot bliss as he filled her vagina with sperm for the very first time. Despite the freakout it had caused her, it was an experience she knew she'd want to feel again. In fact, she wanted to feel it now, and not a moment later.

Sunburst kept his attention on the mare inside the massage table. She hadn't moved from her spot, and her pussy hadn't stopped winking at him. His erection was starting to hurt, and the only thing that could make it better was a mare's touch, be it with the velvety tunnel of bliss before him, or an eager throat and tongue. As he sat there, continued pondering who the mystery mare was. He had ruled out Fluttershy, but could think of nopony else in town that had a coat like that.

A muffled voice came from inside the box, one that couldn't be understood clearly. Sunburst moved to the other side of the box where another hole could be seen, and spoke into it. ,"I'm sorry",he apologized,"but I didn't hear you just now." The voice he heard was needy and insistent, albeit very quiet. It made him go wide eyed as he heard a very clear and very insistent,"Fuck me!" Sunburst couldn't believe his ears. There was no denying the quiet voice from within the box. It was Fluttershy, in all her kind glory, no pun intended.

Fluttershy blushed in embarrassment as she realized she had probably said that a tad too loud and probably clearly enough that she could be identified. She held still for a few moments before she heard a light clip clopping as Sunburst moved back over to the side where her plot was. Had he figured out who she was? Was he actually going to acquiesce to her demand?

She gasped aloud as she felt something lightly press against her passage. She tensed a little in excitement as she realized it was his stallionhood. She smiled and tried to relax as she realized he was going to put it into her. She wanted to go crazy and jump for joy. Hell, she could probably go zooming through the air and pull off some of Rainbow Dash's crazier stunts all on her own with how excited she felt!

Sunburst couldn't believe what just happened only a minute or so ago. One of the most attractive mares in the whole town was offering herself up to any stallion that so desired in this bath house, and he had just eaten her out. His cock was aching something fierce, begging to be buried inside the tight warmth that his tongue had gotten to enjoy. He had gotten his permission, and now had his hooves on the massage table to hold him steady as he lined himself up with the butter colored pegasus's foal maker, and had began to prod at it.

The feel of the warm head of male flesh caused the mare to wink reflexively. He was searching for her entrance, and once he found it, the two would be united in pure, unadulterated bliss. A moment later, and he found what he was looking for, and slowly pushed in.

Sunburst paused to gain control of himself; The minute he slipped inside, her inner walls went to work trying to get his jizz out of him. He held still and fought off the urge to start filling her cavity with his seed. Admittedly, it was something he did want to do, but never without a mare's say so. Once he had calmed down enough, he proceeded to slip more of his length into her.

Fluttershy let out soft grunts and gasps as a stallion once again fed his penis into her. The thick and veiny shaft was rubbing at rather sensitive areas as it slipped further inside her. She had no idea how big he actually was, which made finding out this way that much more exciting.

Sunburst kept apply steady pressure, slipping deeper and deeper into the mare. Her body responded by shifting and spreading apart just a bit so he could get another inch or so deeper. Then her body would squeeze tight around the shaft so as to make his withdrawal create the friction that would drive them both wild. After another second or two, he felt his tip push against a barrier, meaning she had taken all of him inside her.

Fluttershy could feel Sunburst bump into her cervix and let out a groan from the contact. Her first stallion hadn't managed to get as deep into her. She squirmed in place as she tried to adjust herself around his girth, letting out small gasps as her inner walls moved inside to accommodate the intrusion.

Sunburst did his best to maintain control. The hot, soft walls felt amazing to rub against, and her muscles fought to both push him out and keep him in at the same time. He did every trick in the book to keep from blowing his load too quickly. After a few moments, he could feel himself calm down and the pressure in his groin subside.

The two stayed still for a few moments before Fluttershy decided to slide forward a little and then back, letting out a gasp at the feeling of hard stallion meat softly grinding against her. Sunburst felt it and let out a more audible groan of pleasure. Taking that as his cue to commence, he withdrew until only his head and an inch or so of shaft was inside her, then pushed back inside. Both reacted at the sensation of flesh moving on flesh. For Fluttershy, it was from Sunburst filling her full and pushing against her most sensitive places. For Sunburst, it was Fluttershy's velvety soft tunnel squeezing against his sensitive head, driving crazy with pleasure.

The two slowly worked into a steady rhythm, with her pushing back into him and him driving into her depths. Fluttershy let out moans of excitement and pleasure. Her first time had been rough and fast. With Sunburst taking a slower pace and working into all the sensitive spots he could find, she could appreciate all the sensations that she hadn't from the rough treatment of her first stallion.

Sunburst could only hold himself back so much. After about a minute or so of the steady and slow pace, he began to pick it up. He thrust a little more roughly, and was rewarded with a mare clenching harder against his length and letting out moans of pleasure that could be heard from inside the box.

Fluttershy could feel the stallion begin to speed up, yet still push against her sensitive spots, causing her to moan loudly inside the cubby hole. She involuntarily flexed her inner muscles against him in response, her body thanking him for the pleasure in the best way it could. Sunburst's grunts of pleasure could be heard from inside the box, and she could tell her body was having the desired effect on him.

The two ponies picked up the pace more. Sunburst could be heard driving himself against the table, his balls slapping against the side. The pressure was increasing, and his tip was starting to flare. ,"Dang!" he grunted out while trying to focus on not crossing the finish line too soon.

Fluttershy had other ideas, though. She was pushing herself as hard against the hole as she could. The pressure between her legs was beginning to swell, and it would be no time at all before she'd be pushed over to edge to pure orgasmic bliss.

Sunburst was pounding away like a madstallion. Each thrust was deliberately driving against as many sensitive spots as he could. The pressure in his groin was becoming too great, and he knew he was on the verge of finishing inside the mare. He grunted out a warning to her as he was reaching a fever pitch. ,"G-gon-na C-cum!"

,"Inside me!", she answered back,"Fill me!" She was being driven over the edge, and any will to fight it had evaporated long ago. The mare pushed her flanks as hard against her lover as she could and screamed out in orgasm.

,"AAAHHH!"

Sunburst heard the scream from inside the box, and he felt her climax. The soft, velvety tunnels that he had been pushing against had now turned into a vice grip that held onto his cock for dear life. The added pressure was too much for the stallion, and he hilted himself into her on instinct.

,"C-CUMMING! AAAHHH!"

Fluttershy felt his head flare deep inside her, and then a hot shot of stallion seed hit the entrance to her womb. She held herself in place as Sunburst unloaded into her. Each pulse of his seed served to give her a mini orgasm, as her inner walls quivered over his twitching length.

The stallion held still as he unloaded in the mare beneath him. A wave of bliss was coursing through him, and he let out gasps of pleasure with each pulse of his length within her. He tried to recall a time when he'd ever done it with a mare had felt so good, but there simply wasn't.

For Fluttershy, this was hooves down the most pleasurable experience she'd ever had. The way he'd just done it was the way every mare should experience this sort of thing. Of course, they should be face to face with their partners too.

After a few moments, Sunburst finished pumping his seed into Fluttershy but left his length inside. He found the experience of lingering inside a mare's passage to be quite enjoyable. He rested his head against the cushion of the massage table and enjoyed the afterglow. After a few moments, his length had deflated enough to slip free of the mare's orifice and retreat back inside of him.

Fluttershy collapsed onto the floor, quite satisfied with how things had went. She liked how Sunburst had decided to treat her to affection first before he pushed into her and rutted her senseless. A part of her wondered if she should work up her nerve to approach him and try to become involved in a relationship. That thought was scary as usual for herself, but now had an excitement that seemed to equal the fear.

Her thoughts were interrupted by a sensation in her stomach. She looked down her body to see her stomach distending and knew immediately that Zecora's potion was doing its job. She got to her hooves and quickly darted back into the maintenance room looking for something to help with her predicament. Finding only a bucket and mop, she squatted over it and let her body do what it needed to.
