CHAPTER RELEVANT TRIVIA:
In Equestria, a cradle robber isn’t somepony interested in someone too young for them, since the age of consent is whenever a pony gets their cutie-mark. It’s somepony who tries to usurp a parent’s place, thereby “stealing” a foal away from their rightful parents.

The inspiration for the effects of a horngasm came from Romance Reports, by SleeplessBrony. The visual was just too cute to resist, so I incorporated it into my headcanon.

Visiting Family (Twilight Sparkle)

*KNOCK KNOCK*

“I got it!” Twilight called, mostly out of habit, as the castle magically echoed the gentle knocking at the front door in every occupied room. Then she shook her head, slightly exasperated.

“Of course I’ve got it. I’m the only one at home.” she grumbled to herself, as she trotted unhurriedly out of the main kitchen, where she’d been fixing another pot of coffee. (Her third, today—a princess’s paperwork was more exhausting than she’d ever imagined.)

A moment later, as she passed through the map-room, whoever was at the door knocked again. Sure, Twilight could easily open the door with her magic from here, now that she had a clear line of sight to it, but as a foal, her parents had taught her that it was basic manners to be within at least three body-lengths of the door when she opened it. So Twilight briefly sped up to a quick canter, before coming to a stop in front of the doors. Opening them, she saw two unicorns on her front step. A grey mare with a grey- and purple-striped mane and tail, and a blue stallion, with a dark blue mane and tail.

“Mom! Dad!” she said brightly, moving to hug them. Her mother first, since she happened to be standing closer. “This is a nice surprise. What are you two doing here?”

As Twilight Sparkle moved to break the hug, Twilight Velvet used the leg around her neck to pull her daughter into a kiss. After enjoying the feel of the younger mare’s lips for a second or two, the elder slid her tongue between the purple lips. The alicorn happily accepted her mother’s advance, opening her mouth to meet the other mare’s tongue with her own.

Night Light stood to one side, watching his wife and daughter make out. While the sight was nothing unusual, it was still exciting—especially since it had been several moons since he’d last seen it—and his cock started to drop from its sheath. After a minute or so, the two Twilights separated, and Twilight Sparkle turned to her father. She reared up slightly, aided by her wings, and wrapped both her hooves around his neck. After a chaste hug, Twilight kissed Night Light, and was quick to add her tongue.

The pair quickly lost track of time as they made out, but when they finally separated, Night Light saw a bright smile on his wife’s face. One which took on a hint of naughtiness when she noticed him shuffling his hind legs. She may not have hit middle-age yet—her magical power was high enough that her life expectancy could be as much as 180 years—but at 61, she had more than enough experience recognizing the subtle differences in stance (and gait) that identified an aroused stallion.

“Not that I’m complaining, because I’m always happy to see you, but what are you doing here?” Twilight asked again.

“We haven’t seen you in a couple moons, and haven’t had a real visit in even longer.” Twilight Velvet said, her tail swishing in a way that made her arousal clear to her 67-year-old husband. His magical power was a little weaker than hers, but he was still expected to live to at least 140-150, so was just entering middle-age. (Then again, even Twilight, at age 28, could recognize the signs of arousal in other ponies of either gender as easily as anypony her age. It was one of the few aspects of socialization that she hadn’t missed out on when she was younger.)

“Well, you know, the school keeps me pretty busy. Hehe.” Twilight said sheepishly, rubbing the back of her neck with one hoof.

“Oh, that’s perfectly alright, Twily, dear.” Velvet said, pulling her daughter into another hug. “We understand how busy you are. That’s why we decided to get off our plots and come visit you for once, instead of waiting around, hoping for an opening in your schedule.”

As the elder Twilight continued to comfort the younger, Night Light sauntered over to the pair. He stopped when he was shoulder to shoulder with his daughter, and leaned against her slightly, offering comfort and assurance that they weren’t upset with her. Though as he took a couple steps forward, the pressure against her body took on a different meaning. One that made her tail twitch in anticipation.

Night Light kept moving, rubbing his body along his daughter’s. As he came even with Twilight’s flanks, he ducked his head, sticking it right under her tail, without breaking his slow stride. He managed to sniff at her marehood for almost a full second, before he gave a quick snort and pulled his head away, his neck unable to bend any further. The blast of hot air made Twilight gasp slightly, and her tail flagged high.

A second later, Night Light cleared the other, still closed, door and turned himself around. Then he stuck his nose back under the dark tail and started sniffing again. The scent of feminine musk was stronger than it had been before Twilight ascended, and more complicated, but no less pleasant. If anything, the mingled scents of all three tribes was even more erotic, and Night Light’s cock was as hard as it could get almost instantly.

Now that he was ready, Night Light nuzzled his daughter’s lips for a second, using his sensitive nose to determine if she was ready, too. Finding her not quite wet enough, he started licking her. After a few swipes of his tongue, he felt her wink against it, and he nuzzled her again. Her pussy now felt more swollen, and much wetter.

″Ready, baby?″ Night Light asked, bringing one hoof up to rub Twilight’s cutie mark. She bucked slightly at the contact, and he also felt her haunch muscles flexing as she widened her stance.

″I’m ready, Dad.″ Twilight moaned, once she’d positioned her hind hooves in preparation for the extra weight she was about to support.

″Mmm. Do it, Nighty.″ Velvet urged, opening her eyes and looking at him over their daughter’s back. She didn’t stop nuzzling and kissing the purple neck. ″Mount our little girl and ride her like you’ve been wanting to.″

After a few more seconds of rubbing the purple and white starburst, Night Light reared up, his chest just landing on the strong, purple back. He had to shuffle forwards to bring his dick up against the purple lips. Then he gripped her barrel between his hooves and hopped forward again, driving his cock deep into her wet heat.

″BUCK!″ Twilight shouted, her wings flaring out wide. She loved having a stallion bury himself in her all at once, that way. Another thrust, and she felt Night Light’s hips slap against hers, and his cockhead brush against her cervix. A second or two later, after Night Light had steadied his hooves, he started moving his hips, thrusting in and out, hard and fast.

Twilight quickly lost herself in the passionate rutting of a stallion who’d intentionally blue-balled himself for three days in preparation. She was so wrapped up in the feeling of the hard cock filling her that she barely noticed her mom kissing up her neck. And she completely missed the gentle pressure of the grey hoof on her neck pulling her head down. But the words suddenly whispered in her ear couldn’t be missed.

″That’s right, Twily, dear.″ Velvet whispered huskily. ″Feel your father’s weight on your back. Feel his cock filling you up. As you stand here in the door of your home. Your castle. In public, where everypony can see it. Where anypony who comes will see you being rutted by your dad. Isn’t that exciting?″

″Yes! It’s so exciting.″ Twilight moaned. Exhibitionism was more Velvet’s thing, but she knew how to drive her daughter wild with it, all the same.

″And do you know what would make it more exciting?″

″Wha—Ahh!″ Twilight yelped, as a warm, wet mouth closed around her horn. The feel of her mother’s tongue gently swirling around the fluted shaft made her moan louder as her eyes crossed. Then the suction started, and her thoughts became too fuzzy to keep track of.

For the longest time, Twilight just stood between her parents, mindlessly being pleasured from both ends. But eventually, something caught her attention. A tingling feeling. Two, actually. One in her horn, and a matching one in her nethers. They built quickly, feeding off each other, before sparking a dual climax in the young alicorn. Twilight felt her pussy winking madly around her dad’s cock, at the same time as a pulse of raw magic blasted from her horn.

The magical charge filled Velvet’s mouth in an instant, washing over the rest of her body in the next second. It raced along her nerves, lighting them up with pleasure, and making her fur stand on end. It also triggered her climax, making her moan even louder around the purple horn, which only drew out Twilight’s orgasm even longer.

The feel of his daughter’s pussy milking his cock and his wife’s orgasmic noises pushed Night Light over the edge, and he groaned as he unloaded his full balls deep inside his little princess. Not as deep as he could get, though. Since she wasn’t in season, her cervix wouldn’t spread far enough to let him into her womb, but he was still bumping against it.

After her orgasm waned, Velvet took her mouth off Twilight’s horn, and a moment or two later, Night Light dismounted the purple mare, too. His softening dick pulling out with a wet slurp, making Twilight shudder with a minor aftershock. Her horn also flared with another pulse of magic, making his coat fluff up as it washed over him.

A few seconds later, Twilight’s body relaxed, and her tangled tail drooped. Her head, too, to the point her muzzle almost touched the floor. Her wings, which she hadn’t even noticed had flared while she was being rutted, hung loose. Her mane was as frazzled as her tail, and her coat was scuffed in several areas and covered in a light lather. She was clearly asleep on her hooves.

Night Light was little better, after unleashing three days of pent up lust into his daughter’s marehood. The result of which was now dribbling down the inside of one leg. He was struggling to keep his head up.

″We should take her up to her room.″ Velvet said, startling Night Light from his half-asleep daze. ″You look like you could do with a nap, too, Nighty.″ she added with a giggle.

″I’ll be fine for a few minutes.″ Night insisted, lighting his horn and wrapping Twilight in his magic. She was heavier than she had been the last time he’d done this, thanks to the heavier, earth-pony muscle and denser pegasi bones that came with her alicornification, but he didn’t have much trouble carrying her, despite that. At least for a while. He did have to set her down eventually, after he and Velvet got lost in the castle’s labyrinthine halls.

Twilight’s legs had gone limp in Night Light’s field, so she stumbled when she was set down. That woke her enough to get a good look at her parents, and she barely resisted giggling at them. Their manes and tails were frizzed out, like they’d been struck by lightning, and their coats were puffed out as much as they could be. It was a natural result of their bodies safely shedding the raw magic her horn had emitted, but it left them looking more like walking powderpuffs, than ponies.

After learning why they were in a wing of unused guest rooms, Twilight insisted on guiding them to her room. And on doing so on her own four hooves. But by the time they arrived, her second wind was starting to fade. Even though ponies could sleep on their hooves easily enough, it was really only good for giving them a second wind. Like a short nap.

So Twilight didn’t resist when Velvet urged her into her bed. Though she was a little surprised when her parents climbed in with her. Night Light in front of her, holding her close, and Velvet behind her. The elder Twilight made sure she was touching the younger’s horn, which would allow the alicorn’s horn to absorb her expended magic back into herself. It would help Velvet’s hair settle back down quicker.

An hour or so later, the three of them woke up, and once they were completely aware, they started talking. Catching up on what had been going on in their lives. A lot of talk was about the political maneuverings of the nobles her parents were acquainted with. Her family was a member of the nobility, but so minor it was practically in name only. Twilight Velvet was descended from the last leader of the Twilight Coterie. The ponies who’d been responsible for moving the sun and moon, until Celestia had come along.

The members of the Coterie had lost most of their power when Celestia had appeared, and Luna’s appearance, decades later, had stripped them of almost all they’d had left. They’d remained on as advisors, and minor nobility. The Twilight line had been one of the few to retain any degree of power and influence across the centuries since, even if it was only scraps.

But when Twilight Sparkle had become Princess Celestia’s student, the family had regained a measure of importance. In the eyes of the nobility, at least. But much like the princess, Twilight’s parents had wanted to protect her from the political games, so they’d never talked about that part of their lives where she could hear.

All of which meant it was strange, talking to her parents about politics. But since Twilight had become a princess, it had been nearly unavoidable. Even useful, on occasion. It wasn’t long before the conversation shifted to Twilight’s life, though. And the natural topic of interest there was Spike.

″So how has Spike been doing, these last few weeks?″ Night Light asked.

″Ah, so that’s why you’re really here.″ Twilight said with a teasing smile and a knowing nod.

“That’s not really much of a surprise, is it? After all, it’s been over a moon since Spike molted, and we haven’t even seen him once, since.” Velvet said.

“You just want him to rut you, don’t you?” Twilight accused, still half-teasing.

“Well, call me old-fashioned, but I think a colt’s first time should be with his mother.” Velvet responded.

“Spike’s almost twenty. He’s not really a colt, anymore. He just seems like it, since dragons age so much slower than even the most powerful ponies.” Sparkle explained. “He’s more than mature enough to decide who he wanted his first time to be with.”

“And who was it he chose?”

“Rarity—”

“That cradle-robbing fashionista?” Velvet interrupted, before Twilight could say that the all of the girls had been there, too. Mostly so that just in case something weird happened, they could be right there to determine how bad it might be, and what to do about it.

“Mom!” Twilight scolded. “Rarity isn’t stealing him away from you.”

“Then why hasn’t he at least visited? It’s been almost six weeks, after all.”

“That’s because he’s embarrassed. He can’t really control when he gets hard.”

“So what? That happens to everypony! Well, every stallion, at least. Especially when they first become active. Honestly, it happens at any age, really. Even my grandpa would pop boners randomly until the day he died, and he lived to over a hundred and sixty!”

“Except that Spike’s not a pony; he’s a dragon.” Twilight pointed out. “And this is one of those times when it does actually make a difference.”

“How so?” Night Light asked. While the family and their close friends mostly didn’t think about the fact that Spike wasn’t a pony—at least physically—there were times it really couldn’t be ignored. Dietary issues were a big one. Not just the gems, but meat, too. While ponies could eat small amounts of meat, from time to time—and the more powerful ones could eat it more often—Spike needed it regularly. Not as much as a griffon, admittedly, but still maybe half a pound a week. And medical issues had thankfully been few and far between, but they were always a minor emergency that they’d always had to talk to Princess Celestia for. When Twilight became an alicorn, the princess had confided that almost any information she’d given the family came from talking to the old Dragon Lord, Torch. Nowadays, they could just ask Ember or Smolder directly.

“Well, when stallions get hard, their bodies mostly hide it from all but the shortest ponies.” Twilight started. “But as a biped, when Spike’s cocks drop, they sit right out in front of him, in plain sight for everypony to see.”

“Wait. Cocks? They?” Velvet asked, before Night Light could.

“Yeah, like snakes and some other reptiles, Spike has a hemipene. Two shafts, one above the other, in his case.” the alicorn added, with illustrative gesticulation, at the confused look on her parents’ faces. “After he molted, they replaced the…retractable urethral extension that he had before. He pees out of the bottom one, now. And they’re not shaped anything like a pony’s cock. There’s no flare at all—or even a discernible head—and the tips are pointed, which Fluttershy says is like a dog’s penis. But the top edge of the top shaft and the bottom edge of the bottom one both have little barbs, like a griffon’s. Or a cat’s.”

“That certainly is different.” Velvet agreed.

“Yeah, and that, plus the fact that his gonads are internal—also like a reptile—means that everypony stares when they see them. Which makes Spike feel really self-conscious. The townsponies around here are starting to get used to it, but he’s worried about how ponies elsewhere would react. Especially Canterlot.”

“That does make sense.” Velvet grudgingly agreed. “Too many ponies there would react all kinds of bad to something so unusual.”

“On the bright side, at least, that means we’ll have a good reason to visit more often.” Night Light pointed out. “At least you will. With how different his anatomy apparently is, I don’t know about me, really.”

“I don’t know if he’s been with an actual stallion yet, but Pinkie, Rarity, and I have all fucked his ass before, with those futa-necklaces I made.” Twilight Sparkle said, recovering enough to sit up in bed. “Sweetie Bell, too. He prefers to stick his cocks in us, but he likes anal well enough. And we’re teaching him to be careful with his teeth while sucking cock with some of our toys. He’s not quite ready yet, but his claws are so much nicer than hooves, at least.”

“Really?”

“Yeah. They’re a lot softer than they look—softer than a pony’s frog, since they’re not calloused—And they feel great wrapped around a hard cock. A little lubrication, and it’s almost like fucking somepony’s ass.”

“I think I might have to try it. Where is Spike, anyway?” Night Light asked, a little surprised he hadn’t shown up yet.

“He’s, uh, helping Rarity dig up some gems.”

“Her again.” Velvet said, scowling playfully. “Twilight, are you sure she isn’t trying to keep him all to herself?”

“Yes, Mom.” Twilight answered, rolling her eyes. “She’s made it clear to him that she’s not looking for a permanent relationship with him. He ages too slow and would live too long for her.”

“Well, if you’re sure. I think I might have to have a talk with her, anyway.”

“If you insist, Mom. Just keep in mind, her magic’s a little stronger than Dad’s, though she almost never shows it. And she’s even more dexterous than me.”

“I don’t know why that should matter, Twilight.” Velvet said, rolling her eyes. “I only said I was going to have a talk with her.”

“I just wanted you to know, in case it turned into one of those kinds of talks.”

“I don’t have any idea what you’re talking about.” Velvet insisted, with a little sniff. One that was so like Rarity, Twilight couldn’t help smiling.

“If you say so, Mom.“ Twilight said, twisting her head around to give the grey mare a quick kiss. That didn’t end up being all that short, actually. She finally broke the kiss when she felt her dad’s cock growing between their bodies.

“Seems you’re ready for round two—“ *GURGLE*

After the lengthy pause that followed her stomach growling, Twilight sheepishly spoke up. “Oops. I must’ve missed lunch while doing that paperwork.“

“You haven’t changed, have you, Twily?“ Night Light teased. “This is why we let Spike live with you. You’d have starved, otherwise.“

“Round two can wait. Just guide us to the kitchen, and I’ll whip us up something to eat real quick.“ Velvet said, as she moved to the edge of the bed. Still smiling sheepishly, Twilight followed her parents out of bed, looking forward to the promised lunch.
