Gleaming Shield sprinted herself through the halls of crystal citadel and hoped that she would not run into anypony that she might regret. She looked back and saw that she had outran the guard that seemed to be misconstrued and would not listen to what Gleaming Shield had to say. This made her regret giving them the order that if they saw anypony having their way with her wife to arrest first and ask questions later.

Navigating herself through the halls carefully, the rays of dawn bleeding into the large windows off to Gleaming Shield's right. She was running around the perimeter of the citadel, the place where it was easier to outrun his guards and held plenty of hiding places. She rounded a corner and passed the servant's quarters, hoping not to disturb the servant's inside. Likely just now waking up for a full day of cleaning and watching the halls of crystal citadel. They had quite a large staff considering the size of the halls.

She slowed her pace as she rounded a corner, breathing in large gulps of air to try and catch her breath. Running after getting eaten out wasn't exactly the greatest feeling, Gleaming Shield bending down to try and catch her breath easily, attempting to open up her airways. Which in hind sight is not exactly the brightest idea.

Gleaming Shield glared up and growled, "Shut up and keep your opinions to yourself Discord."

'Eris...how many times do I have to repeat myself...I am Eris now. Damn, you must have gotten dumber after you changed.'

"Shut the fuck up..."

'Such foul language from such a pristine mare.'

Gleaming Shield groaned and said, "By the goddesses just narrate the goddamned story!"

'Fine I will. Anyway,'

Gleaming Shield leaned back up and stretched up her hooves. A few pops coming from her back. Quickly dropping her hooves and attempting to run in the opposite direction, running into something soft.

...

Cherry Pie had seen a lot of things at the crystal citadel, and some of them she wished she hadn't. But this just took the case. She rounded the corner and found a beautiful mare. At least the ass end of one. Her hind legs nicely toned and like looking at a perfect upside down U. Her tail flicked back and forth, revealing a pair of bright red lips. Quite possibly the finest ass she had ever seen. Two well rounded and well refined mounds of flesh, clearly shaped for seduction and for attention. Attention that Cherry Pie was willing to give. She dropped her basket of clothes as she stared in awe at the godlike ass that was in front of her.

Cherry had worked at Canterlot Castle a few months ago and always thought Celestia had the finest and biggest ass, but this one dwarfed her own. Her hips large and refined. She stood up fully and her strong muscled back having a thin sheen of sweat running down her coat. The musky scent of sex fresh on the air. Cherry Pie found herself advancing towards the unsuspecting mare. Cherry was now a few paces away from the mysterious mare and the mare turned, before she could react they both came crashing to the ground.

Tripping on her basket Cherry fell down, slamming her head against the crystal floor. She wanted to cuss this mare out but she could not, she was just so pretty. The mare straddling her, her inner thighs clenching around Cherry's own. Her head resting on Cherry's chest, she looked up and stared into Cherry's eyes. Cherry's eyes growing as wide as plates, she was the most beautiful mare she had ever seen. The unicorn blushing and said, "I'm sorry I...I didn't-"

"Don't be sorry...I'm glad that we ran into each other...what is a pretty mare like yourself doing rushing through the halls of crystal citadel?"

Her tone was slightly more husky than she had thought, causing the white mare to blush and respond, "Well I um-I was-"

"Hey! I think I heard her over here!"

The mare growled, "Shit, I thought I outran them."

Cherry looked around and found a utilities closet near them and pointing her hoof at the door she said, "There, go in there."

They both clambered to their hooves to scramble into the closet. The white mare going in first and Cherry following her. It was small and could barely fit one mare, let alone the both of them. But this just gave Cherry an opportunity. The white mare said as Cherry closed the door behind her, "Wait what are you!-"

"SHH!" Cherry moved her hoof up to silence the white mare. Cherry lifting her ear to listen closely.

...
"Look! A basket! She was here! Come on this way!"

Gleaming Shield holding her breath as she heard the sound of three guards charging out of ear shot and finally rounding the corner at the end of the hallway. Releasing a breath of relief she felt the servant mare she knew as Cherry Pie lower her hoof and said, "Okay, now that we're safe-"

Her gaze connecting to Gleaming Shield's, her eyes filled with lust and desire as she moved her hooves down Gleaming Shield's sides. The soft sensitive touch causing Gleaming to release satisfied moans, Cherry said sexily, finishing her sentence, "Now we can get down to business."

Her hooves moved down to Gleaming's butt and she slipped her hooves in between Cherry's and moved them away saying, "No...I-I can't...I have a..."

Cherry moved her hooves down her lower abdomen and causing Gleaming Shield to moan in pleasure. It felt dirty but she could not find in herself to stop. Even though every part of her brain screamed for her not to do this, it was almost like another entity took control of her hooves and caused them to slide up and down Cherry's sides. Only inches away from each other, Cherry forced up against the door. The light dangled on a string and swung back and forth, briefly illuminating her soft yellow face. Her mane and tail long cherry red. Gleaming could not hold it back anymore and allowed the sexual lust to overtake her and hooked her hooves under Cherry's knees and lifted her off of the ground and against the door.

Why was she doing this? She was married, she had a commitment to Cadence and Cadence alone. Why was she letting this mare do such things to her? Why was she suddenly hot right now? She pressed her lips to Cherry Pie and let the tension and all of Gleaming Shields objections to just disappear. All that Gleaming Shield could feel right now was the feeling of Cherry's cold hooves searching over every corner of Gleaming Shield's body.

Her lips were soft and sent waves of lust washing over her, making every kiss electric and continuing her on her haze of sexual desire. In between kisses Cherry whispered huskily, "You...you're good at this..."

Taking this opportunity Gleaming Shield opened her mouth and slipped her tongue inside Cherry Pie. Gleaming Shield dropped her hooves, keeping Cherry raised and resting on her pelvis. The feeling of Cherry Pie's bare marehood pressing against her lower abdomen caused Gleaming Shield to moan and breathe heavily in sexual desire. Her thighs embracing around Gleaming Shield, with her free hooves she caressed the fur around her cutie mark.

The sweet and elegant taste of cherry fresh on Gleaming Shield's lips, if Gleaming Shield wasn't the wiser she would probably think that she was making out with an actual cherry pie. She can feel the pie filling sliding down her slightly irritated throat, finally settling in her stomach. It was a sensational and odd feeling, Gleaming Shield knew that ponies often took characteristics of their special talents but she never knew that taste would be one of them.

Keeping Cherry Pie braced against the door, wrapping her hooves around her shoulders and pulling Cherry Pie in closer. Through out all of this she has always retained a thought of what is wrong with her. She was married, how could she do something like this? She's scum if she allows this to happen and she would be even more scum if her wife figured out about this. Yet something clung her to her overly sexual thoughts, like she has thought back to before, it is almost as if somepony else is controlling her actions. Who could have such a power over the universe that they could change a pony's gender.

'Before you even think about it no it is not me.'

Gleaming Shield grabbed the bottom of Cherry's ass and lowered themselves to the ground, being sure not to break their kiss. Gleaming Shield rolled over and Cherry Pie slipped underneath Gleaming Shield. Pressing her body down to embrace the supple and plump form of Cherry Pie. Gleaming Shield pulled away from the kiss with a loud smock and opened her eyes staring at the mare underneath her. The edges of her eyes blackened and dimmed with the amount of light that refused to illuminate the room. Cherry Pie had her eyes and mouth lulled open, her bedroom eyes staring back at Gleaming Shield with a slight twinkle. Wanting and waiting for what would happen next.

Giving a quick peck on the lips, she guided her mouth to the mare's chin and taking her tongue out she glided it under her chin and to her neck. Cherry Pie giving off a lewd moan of satisfaction at Gleaming Shield's caressing with her tongue. Pressing her tongue into the taught flesh of Cherry's neck, kissed the nice soft fur. Gleaming Shield did this for about a minute before she craned her neck and brought kisses on her collarbone. All that Cherry Pie could do was explore Gleaming Shield's body with her hooves, her hooves travelling to Gleaming Shield's back side. Trailing up her thighs and to grab at the two mounds of flesh, Gleaming Shield let out a breathy moan at the attention her plot had been receiving.

Crawling back Gleaming Shield trailed her kisses down to her chest and tasting her hot and steamy flesh. Gleaming Shield slipped her hooves under Cherry, arching her back at her touch. Sliding her hooves to her lower back and rubbing the fur and skin just above Cherry Pie's flank. Squirming and writhing under Gleaming Shield's hooves, a full body shudder erupting through her very core. Rubbing her hooves up and down Cherry's back, Gleaming continued her pilgrimage down to her true quarry.

Her stomach twitched as she thought about eating out another mare, when she was Shining Armor she never dreamed of doing something like that. She always thought of herself as a gentlestallion and never thought about doing something like that. That however did not stop his curiosity at what it was like, a hard lump forming in her throat at she nervously moved ever closer to Cherry Pie's awaiting marehood. Bringing up tufts of her tommy fur in her teeth, pinching some of the skin on her way down to her waiting reward for her patience.

Lifting up slightly, she stared right at Cherry's awaiting marehood. Glistening in the dim light and bright red waiting for Gleaming Shield to give it attention. Her legs were already spread as she wanted this bad, she let out a soft moan in anticipation for what was to come. Licking her lips, Gleaming Shield prepared herself for what would come next. She would never know what it felt like if she just stared boggled at the bright pink lower lips. Sucking in a large gulp of air she lowered herself nervously to the lips, her heart thumping in anticipation. Cherry Pie holding in a breath and bracing herself harder against the cold stone floor, releasing another moan.

Now mere inches away from the swollen lips, her hot breath spreading over her inner thighs. Gleaming Shield swallowed hard to try and choke back the lump in her throat. She had no idea where to start or how she should start, her mind drawing a blank as to how to start. Pursing her lips briefly at the suspense she lowered herself down and opened her mouth. Drawing out her tongue and giving a long lick up the small chasm of flesh. Cherry Pie ripping a yelp from her throat at the rising feeling of pleasure, electric shocks moving throughout her body. Every muscle nearly tensing at the feeling of Gleaming Shield's tongue working around the soft pair of lips. Lapping her tongue in a large circle around Cherry Pie's vulva.

Gleaming Shield felt every pore and hair on her skin stand up and shudder over her body. She was slow at first but with a purr she increased in her speed and pressed her muzzle against Cherry Pie's love button. Yelps and moans of pleasure escaped Cherry Pie's now open mouth, the shouts of pleasure bouncing off the muffled walls of the closet. Gleaming Shield felt more loose and less tense as she glided her tongue all over the servant mare's pussy. Caressing her thighs, tenderizing the love muscles that Gleaming Shield was now worshipping.

Slipping her tongue inside, breaching inside Cherry Pie caused an ear splitting screech from Cherry Pie. Her breaths becoming more sex driven and more erratic. Gleaming Shield never felt more excited and more anxious than she felt now, not even the first day he joined the royal guards. Her tongue licking along the inner walls of Cherry Pie. Her hips slightly rising and falling at Gleaming Shield's steady rhythm of slipping her tongue in and out of Cherry Pie's wet pussy.

Gleaming Shield could feel Cherry Pie's muscles tense and clench as she let out a cry, leaking mare cum into Gleaming Shield's mouth. The sweet nectar of Cherry Pie spilling over Gleaming Shield's mouth and tongue. She loved the taste of a mare's juices, not to sound too disgusting, but she just found a mare's wet juices just so attractive and sweet on his tongue. Swallowing deep the hot liquid and suckling on Cherry Pie like a source of nourishment. When it was all over and Cherry Pie was done with her climax, she laid there in a sprawled mess. Sweat shining off of her in a thin sheen. Gleaming Shield wiped her muzzle and sat up, that was extremely wrong but so arousing all at once.

The darkness at the edge of her eyes crawled away and she felt her strength return to her limbs. Her conscious returning to her, she felt her skin crawl at what she just did. She was now an unloyal husband and she felt her stomach turn and knot at this display. She stood up and opened the door, pressing her back against the door. The cool air washing over her, leaving the musky and hot closet walls. She slumped down and rested her head in her hooves, folded on her knees. Her marriage was over, if Cadence found out about this it's going to be all over.

Her head shot up and she said, "Then she won't find out."

"Hmm?"

She nearly jumped as she heard somepony next to her. She looked up and was hoping to see anypony but a royal guard, she looked up and saw none other than Flash Sentry. He had his helmet off revealing a well cut face and smooth features, his dark blue mane and tail was a little fuzzy and wild. Considering that he was more than likely finished with his drills and was taking a small break in between that and his guard route. Gleaming Shield stood up fast and said, "Oh Flash, thank the goddesses that you are here."

"I don't think we've met?" Flash said with confusion in his voice.

Gleaming Shield stood up and said catching her balance, "Flash it's me Shining Armor. I was transformed into a mare and now I'm trying to find a way to change back."

Flash seemed unconvinced and crossed his hooves, "Prove it that you're Shining Armor, tell me something that only he would know?"

Gleaming Shield thought for a moment and finally answered, "Back before me and Cadence got married you were shitfaced drunk and accidentally made out with Cadence, I stopped you and you said, "She's still fair game if she's not married." To which I replied with a stiff jab to your face."

Flash blushed slightly and rubbed the back of his neck timidly replying, "Okay..."

He looked back up and said, "I can't believe...hehehehe..."

He started to giggle and then burst into a full, bust a gut, laughter. Gleaming Shield scolded Flash as she said, "What's so funny?"

In between his fit of laughter he wiped a tear from his eye and replied, "You...you are a mare...and you're...and you're Shining Armor, or rather...you were Shining Armor."

Gleaming Shield folded her hooves and said, "My name is Gleaming Shield now...until I transform back..."

Gleaming Shield waited until Flash was done with his laughing fit and Flash asked, "How did this happen?"

Gleaming Shield shrugged her shoulders and said, "I just woke up like this, believe it or not-"

She was interrupted by Flash sniffing close to her, she reeled back and Flash asked knitting an eyebrow, "Is that...did you...have you-"

As if to answer his question they both heard a loud yelp belonging to a mare emanate from the closet next to them and the mare said, "Wait! Where did you go? I wanted to go for a round two."

Gleaming Shield blushed slightly and swiped a hoof through her mane. Flash let an ear to ear grin spread over his beaming face, "No. You. Did. Not!"

Gleaming Shield nodded slightly and said, "Yes...yes I did...but you can't tell Cadence, our marriage would be over."

Flash knit an eyebrow and said, "Wait, but Shining Armor is married to Cadence? And you're Gleaming Shield?"

She thought about it for a moment and then said, "Oh my goddesses, that means she already cheated on me by having sex with me. And i didn't cheat on her because I am Gleaming Shield. Oh thank you Flash, you just lifted a weight off my shoulders."

There was a break in what she was about to ask as she let out a sigh of relief, "So, I was wondering if you could help me find somepony that could fix this."

Flash thought for a moment and said, "Isn't your sister the Element of Magic or something? I'm sure she has an answer for this problem."

Gleaming Shield replied, "I never thought of that, thanks...and there was something else."

She twiddled her hooves as she formed her question in her mind, "So...the guards kind of...walked in, as me and Cadence finished...you know doing it...and lets just say that seeing a mysterious mare in our quarters with Shining Armor nowhere to be found did not bode well with them...so I sort of need a hoof at helping me out of here."

Flash shrugged, "Sure no problem."

Gleaming Shield smiled and they walked on, heading towards the entrance hall of the citadel. A few minutes yet until they would find themselves at the entrance hall. Gleaming Shield smiled as she realized that she was going to be turned into a stallion very soon. At least she hoped so.
