Author's Note
Well, I've gone and done what I initially told myself I'd never do when I joined this site. Well, time I sold my soul to Slannesh anyways.
Eitherway, as I said in the description, this is my first attempt at writing something like this and I'd frankly love some feedback and criticism. Thanks 
The only chapter
“Bye, have a good evening,” Spring said with a polite wave as the customer left the teashop, the bell over the door tinkling as it closed behind her. And Spring let out a sigh of relief. That was the last customer of the day; it was now closing time.
Yawning a little, he glanced at the clock. It was almost nine o'clock in the afternoon; soon enough everypony would be going home and his wife would soon be on the streets with her night shift patrol in the town guard.
Spring smiled at the thought of his wife. His little Doppel; his little lovebug. Sure, most of the town was in a found the thought of him marrying a changeling ridiculous as least and downright treasonous at worst. He didn't give a damn what those ponies thought; what mattered was his love for her and nothing else to him.
Sighing softly, he removed his apron. Hanging it nearby before walking over to the shop’s main door and locking it; flipping the switch to the we're open sigh in the window causing it to go dark.
There was not a soul in the shop aside from him as he cleaned up and turned off the lights before locking the door and heading into the rapidly cooling night air. He was thankful he'd actually brought a jacket as it was actually rather chilly and had to stuff his hands in his pockets lest they freeze.
He knew Dop wouldn't be home when he got back to their small home on the outskirts of Ponyville. She never was; he worked days and she worked days. And he wouldn't deny, the only reason he opened his tea shop, Brew and Remedy, so much later than the other stores in Ponyville was because he actually wanted to spend some time with his wife.
Humming as he walked, he smirked as an idea came to mind.
“Oh, I know she won't mind,” he chuckled to himself. “Now which way to the park was it again?"
The street was quiet as Doppel quietly made walked along in the darkened streets. Her dark blue uniform helping her blend into the shadows as much as she could with her yellow chitinous skin. She could almost pass as a pony in the poor light if not for the fact her all green eyes glowed faintly in the darkness.
“Oh how lucky can one colt be~” she starting singing softly to herself. Night patrols were always boring on your own and frankly she liked the peace and quiet of the quiet streets compared to the daylight hours. Too many ponies around for her tastes; too many eyes on her.
Shaking her head, she drove the dour thought from her mind and left the introspective thinking for later. Right now, she was on the job and it was her Job to make sure that nopony harmed each other and it didn't matter how they felt about her.
As she walked, a sudden chirping filled the air with sound for a moment as the cell phone tucked away in her pocket. “What the?” She said to herself as she pulled out her phone and made the screen activate. A notification for a text message from Spring was on the screen. Opening up her messenger, the message was simple.
What you doing hun
She blinked in surprise at the straight forward text. He knew she didn't like using her phone at work unless absolutely needed and that message was way too quick for Spring. Plus it had no question mark; Spring hated when she didn't put punctuation when she messaged him so why would he not do it?
“You know what I'm doing Spring. I'm at work and I know you know I don't like to use my phone on the job,” she mumbled to herself as she typed before send it and promptly stuffing it back in her pocket.
Starting to walk again, she barely got a dozen steps before her phone chirped again. Pulling it back out of her pocket, she grumbled to herself as she saw it was another message from her husband.
I was just thinking of you and well~
As she was looking at what he sent, another message popped up causing the mares cheeks to turn beet red.
It was Spring, smiling smugly up at the camera of his phone as he held it up above him. His button up shirt was undone and pulled back, exposing his muscular body; but that's not what was making her blush like a schoolfilly. His pants were around his ankles and he was holding his cock in his hand, using it to hold it up for the picture.
And it came with a message. Just thinking my little lovebug could use a pick me up. Meet me in the park.
Her wings buzzed behind her as she looked at the phone and the scandalous picture of her husband.
“Fine, I'll be there,” she said as she typed. Before stuffing her phone in her pocket once again and starting to walk into the shadow of one the nearby buildings before she seemingly vanished into it.
Spring was waiting by one of the town parks bathrooms, leaning against the cinderblock wall as he looked around. A feeling of nervousness building in his stomach. Where was she? Normally, Dop would be her fairly quickly when the option arouse? Did something hold her up?
As he looked around more, he let out a sigh of relief as he saw a pair of green eyes appear in the shadow of a tree before Dop stepped out. The sight of his wife had that effect on him; all his troubles seemed to melt away at the sight of that cute little changeling mare.
“You're a little late my lovebug,” he said walking over to her and hugging hug.
“Oh please, you know it's harder to shadow-walk after dark,” the small mare said as buzzed a little into the air, kissing him on the cheek. It was a necessity unless he bent down; she was just on the five foot mark while he was almost a foot and a half taller than her.
“I bet that made you even more hungry my dear,” Spring said with a small grin on his face as she nodded.
“Yeah it did but we ought to be quick. Chief will have my head if she hears of me doing this,” Doppel blushed a little as she looked around, “again.”
This only made Spring laugh a little as she blushed harder. “Aww come on Dop. You know the look on Night’s face was priceless when she caught us.”
“We almost got arrested for public indecency!” She almost yelled but stopped herself and harshly whispered, “we're lucky it was Night and not someone else. You know how many times I've been reminded of that?”
“A lot?”
“Yeah, a fucking lot,” she hissed a little and looked around. “In the bathroom now bucko.”
“Yes ma'am police officer ma’am,” Spring saluted teasingly as they started to the door. Holding it open for his wife as she entered.
It was one of the private ones; a toilet and sink against the far side of a ten foot by ten foot concrete room. The harsh light of the room’s hurt Dop’s eyes as her eyes adjusted but it was soon gone as Spring locked the door behind him.
Before she could even say a word, he was on her holding her close as his hands went to her back. Feeling for the straps holding on her uniform’s leather breastplate. Her head close to his chest as he worked; she couldn't help but feel comfortable in his grasp. The warmth of his body though his shirt calmed her, made her feel at ease as he undid the straps. Begrudgingly letting her go, he pulled off her chest plate and casually tossed it aside before his pulling her back in.
Spring exhaled into her mane and his hands found the base of her elytra and started massaging and kneading the muscles they were anchored to. Doppel moaned and slumped against him as he did. There was no one else she trusted to touch her there, and Spring literally had magic fingers when it came to how he treated them.
“S-stop Spring! Stop!” It took all her will to say it as he let go of her in suprise.
“Huh? What's the matter?” He looked concerned, “I thought you like that?”
“I do. I really really do,” she said, blushing hard as her wings buzzed a little. “It's just I still got to go back to work. And when you do that, we tend to go all the way and we don't have the time for that right now.” However a grin grew on her face as she eyed the bulge in the front of her husband's pants.
“But we do have time for this,” she purred as she dropped to her knees in front of him, her face eye-level with his crotch as she started to undo his belt.
As she unzipped his pants and undid his fly, her hands went under his waistline and tugged down. She grinned as her prize sprang up, free from it's cloth prison.
“Oh, somepony is already excited,” she chittered, her eyes looking up at Spring as she wrapped a hand around the base of his dark green shaft and started stroking slowly. “You just couldn't wait for me to get here? To get all the sweet love I can from you.”
This earned her a moan from him as precum started to ooze from the tip of his cock. Sticking her tongue out, she licked it off, earning a small gasp from him. She hmm’d in thought for a moment, “I think I need to get a better sample.” And with that, she opened her mouth wide and took his head in her mouth.
Spring groaned loudly as he looked down at her, a hand going to her mane as she she started to sink the cock more into her mouth; bobbing her head as she did so.
He started to pet her mane. “I love you so much my little lovebug. So fucking much that I can't even describe it.”
She looked up at him, smiling up at him as best she could with his cock bobbing in her mouth. She knew it was true; she could feel the love coming off him. It was like a fine aged wine; aged and perfect. No stallion or mare would ever catch their eyes like they did for each other.
She continued to bob her head steadily on his cock; gradually making her way lower and lower. The taste of the musky flesh and every musky breath of air she took was enough to make her loins burn. And by Celestia's solar flaring orgasms, did she want to strip and ride him till the sun rose. But she had to control herself.
Soon, his ring was brushing against her lips as she went. Spring's moans were music to her ears; his eyes closed before he squeaked in surprise as he felt her finger prodding at his backdoor. Relaxing, he felt it slip in his ass as she found her mark; adding more sensations to the mix as she started to tease his prostate.
“F-fuck Dop, I.. I'm close~” He was close, so very close.
As Dop started to feel his head beginning to flare in her mouth. She stopped, opening her mouth wide, she pulled away; leaving her husband's hard cock saliva coated as she pulled her finger from his ass.
Confused, he looked at her, his cock already softening even as he watched her walk over to the sink and wash her hands. “Huh? Wha? Dop, I was about to cum,” he whined.
“Yeah, you were going to get to. But you forget I'm on the clock remember?” She said as she wiped her hands off on her pants. “so I don't get to have the fun I want till I get off work and till then you don't get to cum either. That sound fair enough?”
He looked confused but nodded, “yeah, sounds fair.”
And as she picked up her breastplate from where he'd tossed it, she grinned devilishly as an idea came to her mind. “If you be a good boy, I'll let you fuck me till I can't see straight. In the ass too if you want. But if you don't do as I ask, I'm going to fuck you.”
After saying that, she licked her hand, changling slime sticking to her palm as she walked over to her husbands and smeared it all over the head of his shaft. "If that's broken, you'll be the one sitting funny tommorow love."
He squeaked, his tailhole reflexively clenching. “Griselda?” The memories of the last time she used that on him made his ass hurt already.
“Damn right, I'll use Griselda on your ass,” she said as she finished strapping her armor on.
Walking towards the door, she buzzed into the air and gave her husband a kiss on the cheek. “Love you and thanks for the pick me up. I really needed this; now I have something to look forward to when I get off of work. See you later!”
And just like that she was out of the bathroom leaving Spring standing there, pants still around his ankles.
“Love you too hun.”
