It Takes a Family to Raise a Flurry

"Hey Mom, does it seem like Flurry Heart has been acting strange lately?" Shining Armor asked.

"What do you mean?" Twilight Velvet asked.

"Well, it seems to me that she's just been acting strange lately."

"Sweetie, you're just saying the same words over again. Can you be more specific?"

"Well, I've noticed that she's been acting more... provocative. The way she phrases things with those little innuendoes of hers. The way she walks around me with her tail up and... I don't know... Just the way she looks at me sometimes... It's almost like she's flirting with me."

Velvet waited. "... And?"

"And she's my daughter!" Shining said.

"And you're my son."

"What does that have to do with anything?" he asked.

Velvet raised an eyebrow. "Shining, you of all ponies should be sympathetic. Do you not see the hypocrisy here?" she asked.

On the mattress in front of her, Shining lifted his dripping face from between her legs. "What?"

Velvet motioned between them. "How is this not the exact same thing?"

"This is completely different! You're a mare that's older than me. I can't sexually aggress you."

Velvet scoffed. "Excuse me? You clearly remember things differently than I do."

"What are you talking about?"

"You really don't remember how this started?" she asked. Shining wavered. "I remember that first spring after you got your cutie mark, puberty hit you like a freight train. You were trotting around the house belly-slapping without a care in the world. Oh, the other mothers I knew tried to warn me, but I didn't believe them. But once school had let out for the summer, you followed me around the house like I had you on an invisible leash. You thought you were so sneaky, trying to get your nose up under my tail ever chance you had, sneaking little licks of my pussy as if I wouldn't notice."

Shining looked mortified. "Why would you let me do that? Why didn't you stop me?"

"You think I didn't try?" she asked. "But you were incorrigible. And I... I was weak."

"No, don't blame yourself!"

"It's true. I should have been more firm with boundaries and... and I should have kept taking my Beat The Heat. But I didn't."

"Mom?"

Velvet's eyes fluttered. "Shining, you have to understand that at the time, your father, he... he hadn't come to appreciate... that part of me the way he does now. And you were just so eager..." She bit her lip. "It just felt so good to feel wanted so earnestly, and I let you." She rubbed her forehead with her hoof. "I don't know when it happened exactly. That summer is a bit of a blur to me now. But you started getting more aggressive in your attempts to... mount me. And I... I let it happen."

Shining frowned. "I'm sorry."

Velvet shook her head. "Don't be. It's not your fault. You were just a colt that didn't know any better. I should have... I should have been more... I failed you as a mother."

Prince Shining Armor of the Crystal Empire, the former Captain of the Royal Guard of Canterlot Castle, looked around the Princess-Mother's Crystal Palace suite. "For a given value of failure, I suppose."

Velvet smirked at him with that knowing look that only a parent could give their child. "Thank you, for making my point."

Shining Armor looked genuinely confused. "How long ago did all that happen?" he asked.

Velvet tapped her chin with her hoof. "How old is Twilight?"

The question hit Shining like a bucket of ice water. "Do you really think Twilight could be my daughter!?"

Velvet shrugged. "The timing fits. But your father could tell that I had stopped taking my Beat The Heat, too. Or at least, his dick could tell. Between the two of you that summer..." Shining waited while Velvet trailed off with a goofy smile at the memory of that summer. "... I give it fifty-fifty odds."

Shining balked. "And you never thought to get a paternity test?"

Velvet looked incredulous. "For what purpose? To go after you for foal support!? You were barely out of junior high school!"

Shining felt like he was going to throw up. "How could you have let me... let that happen?"

Velvet smiled. "Give yourself some credit, dear. While you may have lacked the experience, you were so- so eager to please! And you just had a natural-born talent for it. I knew that you would make a mare a very happy wife some day. When you ended up marrying a princess, everyone else was surprised... but not me." She winked. Shining blushed. "And you've only gotten better as you've grown," Velvet purred. "Speaking of..." She rubbed the side of her leg against his erection. "Now where were we?"

Despite his erection, Shining wavered. He held his head with his hooves. "Mom, I just... This is all just a lot to take in!"

"You're telling me!" Velvet purred, licking her lips as she eyed her son's throbbing, veiny shaft.

"Mom, come on, that's not helping!"

"How about this?" she asked, taking it in her magical grasp, gently stroking him. Whatever concerns were plaguing his mind quickly flittered away like leaves in the autumn wind. She leaned over and started licking and sucking his dick. "Hmm, there you go. Let Mommy kiss it all better." Shining moaned. No matter how many times they did this, it never stopped feeling special. She really knew how to put in the effort.

He struggled to even focus his eyes. But he managed to look at her, laying there on the mattress in front of him as she blew him. Another question nagged at his mind. "What about this one?" Shining asked, gently placing his hoof against Velvet's gravid belly. "Mine or Dad's?"

Velvet's eyes smiled and she slowly pulled his dick out of her mouth. "I give you two fifty-fifty odds."

A sudden and obvious realization washed over Shining. "Wait! Does that mean that I've already fucked one of my daughters?"

Velvet rolled over and spread her legs, guiding his dick towards her pussy with her magic. "One of you has."
