A beam of morning sunlight shone through the window, dancing across Fleur’s face and causing the unicorn mare to stir from her sleep as the light pierced her eyelids. Grumbling, Fleur yawned as she stretched herself out across the bed, sitting up to rub the sleep from her eyes. Still half asleep, Fleur moved on autopilot as she rolled out of bed and into the bathroom to get ready for the day.

As she walked into the bathroom, her eyes fell on the waist bin in the corner, and the tightly wrapped remains of a very used diaper yet to be thrown out.

Fleur was jolted awake as the events of last night came flooding back to her. Her diapered fun, her messy “accident”, Fancy Pants standing in the doorway… and spanking her until she orgasmed into her messy diaper… Just thinking about it made Fleur blush from excitement.

It… it really happened…

Standing frozen in the bathroom doorway, she remembered what Fancy Pants had said to her: Daddy loves you. Somehow repeating that simple phrase to herself managed to help Fleur calm down enough to not have a panic attack right then and there. Walking up to the mirror, Fleur did her best to look presentable, washing her face, brushing her mane and tail, and putting on a tiny bit of makeup before she was satisfied with herself.

Walking to the doors of the bedroom and poking her head out, Fleur called out, “Fancy Pants?” After getting no response, she tiptoed out into the hall and began a slow descent down the stairs. As she reached the main floor, her ears perked up at the sound of someone in the kitchen, followed by the sweet smells of eggs and hay bacon. Drawn by the delicious smells, Fleur entered the kitchen to find Fancy Pants standing in front of the stove. “Fancy?”

“Ah, morning, Fleur!” Fancy Pants greeted as he walked over to her and gave her a quick nuzzle. “You’re just in time, breakfast will be ready in just a minute so please take a seat and I’ll be with you soon.”

Fleur was at a loss for words, dumbfounded at how casual Fancy Pants was being after what he had seen last night. “A-about last night…” Fleur stuttered, but was stopped when Fancy Pants pressed a hoof to her lips.

“Ah, ah, ah… there’ll be plenty of time to talk about that after breakfast. You must be hungry after your long nap, after-all…”

Her stomach betrayed her by letting out a loud growl, prompting Fleur to blush as she wordlessly trotted over to the table and sat down. She didn’t have to wait long before a plate was slid over to her, loaded high with scrambled eggs, hash browns, and hay bacon.

Levitating his own plate next to him, Fancy Pants took a seat as well as he set the plate down. “Well, as they say in Prance, Bon Appetit.”

The two ate in relative silence save for the sound of cutlery scratching against their plates. Fleur always enjoyed when Fancy Pants cooked. Despite being a noble, he preferred to do daily tasks like cooking and cleaning by himself rather than delegate them to maids and servants, something that most other nobles frequently scoffed at him for. But Fancy Pants never believe he was above doing things like a “normal pony”, which was yet another thing that Fleur absolutely adored about him.

It also helped that he was a fine good cook, not the best obviously, but Fleur could never complain after eating the food he made.

Eventually the pair finally finished eating, sitting back in silence as both waited for the other to speak. Just when the silence was moments from becoming suffocating, Fancy Pants finally spoke, letting out a sigh as he propped his hooves up on the table. “So… you’ve been keeping secrets from me, haven’t you?”

Fleur refused to meet Fancy Pant’s eyes, too ashamed to look him in the face. “Y…yes…” She squeaked out, rubbing a hoof against her foreleg. “I’m sorry for keeping this from you but… I can’t imagine how disgusted with me you must be… walking in to find me like… like… that…”

“On the contrary, my dear…” Fancy Pants interjected. “Last night was actually not the first time I saw you being such a very naughty filly.”

“Wha… what?” Fleur asked in disbelief. When could he have…

“It was several weeks ago, you see,” Fancy Pants began, “And I was on my way to my usual meeting with some of my friends, when it occurred to me that I had forgotten something back home. Despite knowing that it would take me far too long to go back and get it, I decided to retrace my steps and soon returned to our little abode. It is here that I do admit to being a tad naughty of my own, peeking in the window to see if I could catch a glimpse of my dearly beloved… and what a sight it was.

“Naturally you can imagine my surprise upon looking in to find you, the very apple of my eye, my darling Fleur, happily prancing around the house in what was very clearly an imitation of a foal’s diaper. A very used diaper I might add, begging for an imaginary pony to “punish you” and all that.”

Fleur wanted nothing more than to sink into the ground right then and there, her normal cream coat turning bright red with ever passing moment.

“As I watched you more and more,” Fancy Pants continued, “I found myself become that much more mystified… while at the same time becoming more and more turned on by what I was seeing.”

Snapping up to finally look over at Fancy Pants, Fleur’s mouth hanging open at the sight of the smile across the stallions muzzle. “Wha… what?”

“Indeed, for that was my reaction as well. After a bit of research and much thought, I think I may have figured out why the sight of you in such a way aroused me as it did.” Leaning back in his chair, Fancy Pants looked Fleur straight in the eyes. “You’ve always been a very commanding and in charge mare, something that I’ve always adored you for. However, seeing you like that, in a much more ’submissive’ role awakened something inside me, a strange yet not unwanted desire to take charge and be in control like you are. I could never bring myself to command you do something with that much authority without feeling guilty of myself, but if you were willing to try…”

Pausing, Fancy Pants reached into the pocket of his jacket and pulled out a rolled up scroll, sliding it across the table towards Fleur.

“What’s this?” She asked as she picked up the scroll in her magic.

“A contract, if you will. While I know neither of us would want this to ever become public, consider this a written agreement between us regarding a little… experiment I wish to attempt. Take your time and let me know what you think.”

Unfurling the scroll, Fleur began to read, her eyes widening at what was written before her.

This document will serve as a formal agreement between the parties of Fancy Pants and Fleur De Lis regarding a personal and secretive matter. By signing this agreement, both parties agree to the following conditions:

1. While at home, Fancy Pants will be in charge. During this, Fleur will refer to him only as “Daddy”.
2. While free to dress however she wishes out in public, while at home, Fleur will be diapered at all times.
3. While diapered, Fleur will not be allowed to use the washroom for the purpose of relieving herself.
4. Should she be in need of having her diaper changed for any reason, Fleur is forbidden from touching our removing her own diapers, and must ask Fancy Pants to do so for her.
5. Failure to adhere to these rules will result in punishment befitting Fancy Pant’s digression.
6. Should Fancy Pants command Fleur to do something she is not comfortable with doing, it is Fleur’s right to use a previously agreed upon “Safe Word” to render all previous rules of this agreement null and void until such a time she agrees to re-engage in this agreement.
7. Fleur will never be shamed or punished for using the previously agreed upon “Safe Word” at any time.

Fleur’s blush only grew brighter as she read further and further, her heart fluttering in her chest as she imagined all her wildest fantasies becoming a reality. After reading the scroll a second time, Fleur cleared her throat as she said, “Well, this is certainly a … thorough agreement, I will say.”

“I wanted to cover as much as I could. Is it to your liking?”

“Hmm…” Setting the scroll down, Fleur crossed her hooves as she considered the agreement. “Let me see if I understand this correctly. If I sign this agreement, I will thus be putting you completely in charge of our relationship, correct?”

“Yes,” Fancy Pants said with a nod.

“During this time, while we are at home and away from the public, I will be required to wear d-diapers at all times, and must use them for their intended purposes. Furthermore, I will be unable to remove them if I so desire and must inquire for you to do so. Failure to adhere to these rules will result in me being punished like the naughty filly I am, correct?”

“Y-yes.”

“Then, at any point during these events, I will be allowed to use a ‘Safe Word’ to immediately nullify these rules, am I right?”

Another nod from Fancy Pants. “I would feel terrible if I knew I made you do something you weren’t comfortable with, especially if I accidentally hurt you in the process.”

“Hmm…” Fleur tapped a hoof against her chin for a moment in thought. “Coconut.”

“I’m… sorry?”

“That will be my safe word, Coconut.”

“But… but you dislike coconuts.”

“Exactly.”

The proverbial lightbulb went off above Fancy Pant’s head. “Ah, I see. Do you have any more questions?”

“Just one… do you have a quill I could use?”

Smiling, Fancy Pants left the room briefly to retrieve a quill and inkwell, setting them on the table between them. With graceful strokes, Fleur signed her name on the line at the bottom of the document, followed by Fancy Pants signing his name right below hers. With the document now signed, Fleur climbed down from her seat and trotted over to give Fancy Pants a quick kiss on the lips. ‘I love you, Daddy.”

“I love you too, my adorable little filly. Now…” Licking his lips, Fancy Pants said, “I think a certain filly needs to be put into a fresh diaper before she makes a mess!”

Smiling, Fleur followed behind Fancy Pants as they headed upstairs, her tail swishing behind her in anticipation and excitement.

Author's Note

The inspiration for this story came to me while reading up on BDSM relationships. I have seen some interpretations where the relationship between a Dominant and a Submissive is, frankly, unhealthy, with the Dom acting like the Sub is little more than a toy or object to be used and then discarded. However, I realized that, at it's very core, a Dom/Sub dynamic is rooted in one thing: trust.

In a healthy BDSM relationship, both the Dom and Sub can only have fun knowing that the other is enjoying it as well. The Sub trusts that the Dom will only take things as far as they're comfortable with, while the Dom trusts that the Sub will let them know if they go too far or do something the other isn't comfortable with, hence the use of a Safe Word to instantly put a stop to the session. It's also why ignoring a Safe Word when used or shaming a sub for using a Safe Word are two major taboos, since it utterly destroys the trust between you and ruins the very foundation of the relationship.
