Night Light and Twilight Velvet were on a train heading for the Crystal Empire. It had been seven years since the events of Harvey Horsestein and their marriage was largely reconciled. Princess Cadance’s marriage counseling sessions had worked wonders though the sex was more memorable than the lessons.

Velvet had finally retired from writing and Night Light had joined her in retirement. While he didn’t mind serving his daughter as her personal advisor, the pay cap for retirement as a public servant maxed out at 30 years of service. Since he couldn’t earn a promotion for a higher wage level and the retirement cap had been met, he had no reason to continue to work. 50 years old was young to retire and Twilight had been sad to see him leave her service, but she still found time to service him when they both had time. Night Light was looking forward to what retirement offered him, especially since it gave him more time to be with the mare that he loved.

Twilight had three foals from her father, Prince Night Sparkle, Princess Velvet Night and Princess Shining Dawn. Incest within the Sparkle family had been largely normalized, and Shining Armor had joined the group action by becoming Gleaming Shield for ‘her’ father and remaining Shining Armor for his mom and sister. Shining Armor confessed that he found it extremely satisfying to be fucked as a mare and was completely shocked by how satisfied her father had left her, giving credence to why Twilight and Cadance enjoyed Night Light’s company as much as they did. Shining played by the rules and didn’t cheat outside of the relationship group, which pleased Night Light, but Night Light was also becoming a little more paranoid about the grandfoals entering the incest picture. They were getting older, and it wasn’t like they would be excluded from the fun forever.

Night Light mused out loud to his wife. “I’m glad that we’re finally going to see the Crystal Empire in pony, as Cadance and Shining have always come to Canterlot to see us, but I’m a little uncertain as to the timing.”

Velvet tilted her head. “What do you mean?”

Night Light rubbed the back of his neck nervously. “Well. Flurry Heart’s 10th birthday is coming up and I’m grateful to receive an invitation, but it seems like there is more to this.”

Velvet giggled. “Well. Incest is normal in our family now, but Cadance knows how you feel about foals. Ten years old is rather young and I don’t think that Cadance would try to push you past your limits. Try not to worry so much…”

Shining Armor met his parents at the train station and escorted them to the castle. He was extremely tight lipped as if speaking would cause him to break. He led them to the throne room and then stepped aside, allowing his wife as the actual ruler of the Crystal Empire to speak.

“I’m grateful that you both came so far for Flurry’s birthday. Was the journey hard?”

Night Light shook his head. “No worse than any other train ride I’ve ever had. We’re both glad to be here but I’ll confess to being a little paranoid. I worked as an advisor to Princesses long enough to know that there is more to this than attending a foal’s birthday party. So, spill it.”

Cadance winced at the pointedness of Night Light’s statement. “As you know, my parents passed away before I became an alicorn. But… since my husband’s parents are alive, I am obliged to give you both the titles of Emperor Dowager and Empress Dowager of the Crystal Empire. You will advise me on matters of importance, much like you did for Twilight while acting as her Royal Advisor before your retirement. You may travel, with a royal stipend from the Empire, but you will be expected to live in the Empire full time and enjoy the perks of being royalty.”

Night Light and Velvet were shocked. They looked at each other uncertainly. Night Light cleared his throat. “I guess that makes us official citizens of the Crystal Empire. Are there any laws we need to be aware of now that were citizens and not just visitors?”

Cadance nodded. “Just a few. First, Incest is legal in the Empire and always has been. Furthermore, there is no minimum age for the start of relations concerning incest. It is expected for the parents and grandparents of foals to teach them sexual education. And in Flurry Heart’s case… the grandfather is expected to be her first partner.”

Night Light froze in place. Velvet tried to comfort him to no avail. He spoke tightly. “How exactly is that supposed to work?”

Cadance sighed. “The tradition is old. It is assumed that if the family can’t love a foal, then the Empire shouldn’t accept them either. If you reject Flurry Heart, it will be as if you didn’t approve of our marriage and of the conception. You must make love to her, turn her into a mare, or, by the traditions of the Empire, I must disown her.”

Night Light was sweating despite the chill in the room. “But she’s so young! She hasn’t even had her first heat yet. I must do this now?”

Cadance nodded again. “A Creampie is expected. It’s better that it happens before her first heat, so you don’t sire a foal. Unless… you’d rather wait and sire a foal… I approve, of course.”

Night Light stood stock still, completely unable to respond. Shining Armor cleared his throat. “It’s okay if you want to sire her first foal. It’s not as if I wanted that honor…. We know that you gave Twilight three foals…”

Velvet’s glare at her son cut him off mid-sentence. She tutted. “Of course, Night will deflower Flurry as tradition requires. We, of course, accept the titles being offered and Imperial citizenship. But please don’t rush it.”

Cadance smiled with a hopeful expression. “I hope that you’ll join us for dinner tonight. Flurry will be there.”

Night Light nodded. “I wouldn’t miss it…”

Night Light railed against Velvet. “What the fuck am I supposed to do!”

Velvet shrugged. “Fuck Flurry and bucking enjoy it? Give her extra cream to show her that you love her?”

Night glared at his wife. “I’m being serious.”

Velvet nodded. “So am I. We are Imperial Royality now, officially, and we have royal duties. We have to offer advice on matters of importance. I’m sure our ‘vacations’ will include royal duties to wherever we are visiting… and now you have the royal obligation to fuck Flurry Heart. Could you imagine her being thrown out of the castle at ten years old? What she would have to do to survive would pale in comparison to you having sex with her.”

Night Light considered the point and sighed. “But at her age…”

Velvet cut him off. “She’s the same age that Twilight started to pine after you. Given the laws in the Empire, even if Flurry adored her father sexually, she would know that she would have to have you first. She either wants you or she doesn’t. Maybe you should ask her before you try to dismiss it outright.”

Night Light considered the point at face value. “Okay… I’ll ask her at dinner.”

* * *

“Please fuck me tonight!” Flurry Heart exclaimed.

She was wearing a white dress to dinner that might have passed as a simple wedding dress. Night Light was forced to remember the white dress that Twilight wore the night he had deflowered her. Her parents were silent, unable or unwilling to interfere with the traditions of the Empire.

Night Light sighed. “Are you sure you’re ready for this, young lady?”

Flurry Heart nodded vigorously. “I’m so ready! Look!”

She lifted her dress to show Night Light a soaked pussy that was winking rapidly. Night Light swallowed hard. “That… is an eager pussy.”

Flurry smiled warmly. “Basic Imperial Law was one of the earlier lessons I took. I’ve known for awhile that you would be my first and I was sad that you and grandma didn’t visit more often. Dad has been waiting patiently for his turn, but you have the honor of being my first. Please don’t force me to wait up to three more years. I mean… I would gladly accept your foal if you wanted to wait for my first heat, as mom suggested might happen, but I kinda want to fuck dad too but you have to be first. Please, grandpa?”

Night Light looked at Velvet and she nodded. Night sighed. “I love you enough to make love to you. Eat your dinner and prepare for tonight.”

Flurry Heart squealed. “Thank you, Grandpa. I promise that you’ll be satisfied.”

Night Light sighed.

There are limits to being satisfied.
