The Fountain of Youth

"Where did all these come from?" Prince Shining Armor asked, looking at the tired stallion in the mirror. He touched his hoof to his two-tone blue mane, finding more grey hairs.

Princes Cadance appeared beside him, as young and vivacious as she ever was, and just smiled. "I like it. I think it makes you look distinguished."

"Well, I'm glad you like it," he said. He could only see his age, not just in his grey hair, but in the bags under his eyes, and the beginning of some wrinkles. He felt his age, in his back, his hips and knees. There was no denying it; he was getting old. "Though I guess it's not really a mystery where all these grey hairs are coming from," he grumbled.

"Ruling an empire does have a way of aging a pony," Cadance said.

Shining laughed out loud. That was not even remotely what he was referring to. No, the biggest source of his stress, anxiety, and grey hairs was far away... in Ponyville.

"That filly is taking years off my life."

"Flurry Heart! Do you have any idea how much trouble you're in right now!?" Princess Twilight Sparkle scolded the younger mare. "I know I promised not to tell your parents about you dating somepony while you attend my school of friendship, but you can NOT be having a relationship with a foal!"

"Auntie, he's not a foal!" Flurry Heart said. "It's Pound Cake! He's older than I am!"

"Flurry! He looks like he just got his cutie mark!"

"It's Pound Cake, I swear!"

Twilight looked over at Headmare Starlight Glimmer who just looked back with uncertainty. Twilight closed her eyes for a moment and took a deep breath. "Wait here. Do not move from that chair." She walked past Flurry out of the office to the next door down in the hallway, where Guidance Counselor Trixie was talking to the young colt.

"Twilight, I think he's Pound Cake," Trixie said.

Twilight cast a changeling disguise nullification spell on the colt. The same one that Trixie had also cast. The same one that Starlight had cast as soon as she found him with Flurry. The young colt remained unchanged.

"Twilight, it's me, Pound Cake! You know I'm nineteen!"

"What happened?" Twilight asked.

"He says he doesn't know what happened," Trixie said.

"He can answer for himself," Twilight said.

"I don't know what happened! I just woke up like this!" he said.

"Come with me," Twilight commanded. The young colt followed Twilight back to Starlight's office. She sat him in the chair next to Flurry's. "Starlight, may I borrow your office for this?"

"Sure." Starlight got up to leave.

"And Starlight-"

"I know, I know," Starlight said. "Confidentiality. My lips and Trixie's are sealed."

"With each other's," Flurry said under her breath.

"I heard that," Starlight said from the hallway as the office door shut.

"..."

Twilight looked at Flurry and at the young colt sitting next to her. "Pound Cake?"

"That's what I've been saying!" he said.

"Flurry, I don't know what kind of kinky roleplay shenanigans you two are into, but age magic is incredibly advanced, and dangerous! You know better than to cast spells like that on another pony! Without precise thaumaturgy, you could have turned him into a fetus!"

"But I didn't use any magic!" Flurry said.

"Pound already told me that you did," Twilight lied.

"No I didn't!" he said.

"Yeah, you're supposed to split us up when you do that," Flurry said.

"Dammit," Twilight cursed. "Okay, listen, this is a serious situation that needs to get un-fucked right now! For the sake of all of us, you need to tell me exactly what happened!"

Flurry Heart checked the hallway twice before she pulled the young stallion along to her dorm room. Would tonight be the night? he wondered.

"We can't go all the way," Flurry said before she grinned. "I'm not safe. But we can use our mouths." She licked her lips as her hoof reached underneath him to play with his sheath.

"I... I want to be able to kiss you after," Pound Cake said. "And I don't think I'd want to if you... you know, did that."

"Another magic job?" she suggested.

"I'd like that," he said. Her horn started to glow. "But- but before you do that... I... I'd like to use my mouth. On you. If... if you'd still want to kiss me afterwards, that is. I'd understand if you didn't."

She tousled his mane. "Yeah, that doesn't bother me!"

She laid on the bed and spread her legs. He kneeled on the floor next to the bed and started jerking himself off as he leaned forward to lick her pussy. He felt her magic push his hoof away from his dick. Her magic stroked his shaft as he licked her for the first time. "You taste amazing!"

"I know," Flurry panted. Pound Cake was doing a very good job of getting her closer to cumming. "I... I need to warn you... when I cum, I get really extra wet."

Pound looked up from his diligent lapping. "Wait, you mean you're a squirter!?"

"Okay, so I guess you know," she breathed. Pound Cake only licked faster with more intensity. "F-fuck! And here I was worried- Nggh! Pound, I- I'm gonna..!" Pound cupped her entire vulva with his mouth. He kept licking and sucking as she came hard. "F-fuck yeah! Suck my squirt! Swallow it!"

Princess Twilight threw her hooves up. "Okay! I don't need to know every single detail!"

Flurry Heart blushed. "Sorry."

"So what age spells did you use?" Twilight asked.

"I didn't use any spells," Flurry said. "I swear!"

"I mean, aside from jerking me off," Pound said.

"Okay, yes, I did that, but it's not like I did anything special to, you know, milk his age out of him through his dick."

Twilight rubbed her temples with her hooves. "Okay. This is what's going to happen next. I'm going to work with Starlight to very carefully get him back to his proper age before I have to explain to Mrs. Cake that my niece fucked the age out of him for some twisted colt-con roleplay."

"But I-"

"And then none of us will ever speak about this again. Is that understood!?" Twilight said. The other two both nodded. "Flurry, back to your room. Pound, come with me so we can get you fixed up."

"This is bullshit!" Flurry Heart swore as Guidance Councilor Trixie escorted her back to her dorm room.

"I agree," Trixie said. "But take it from me... With everything that Starlight and I have done, I've realized that it takes a lot to get Twilight this upset. So I'd take this whole thing seriously until they can figure out what happened. After that, I'm sure she'll be quick to forgive you. But for now, just keep your nose clean." Trixie smirked and winked. "And his."

"But I didn't do anything wrong! I'm an adult! I should be able to... do stuff whenever I want!"

"Again, I agree. But you're an alicorn. Until she figures out what happened, you need to be careful with your magic. I know you didn't mean to jerk his age out of his dick-"

"I didn't!"

"Like I said, I know you didn't mean to-"

"I mean that's not what happened! I barely even used my magic at all! Aside from..." She blushed, making a jerking motion with her hoof.

Trixie put her hooves up. "Look, I'm not calling you a liar. I'm really not. All I know is that there is three sides to every story; Your side, his side, and the truth."

"I'm not angry at you," Princess Twilight Sparkle said to Pound Cake as she sorted through her books. "Let me just be clear about that."

"Am I going to get in trouble with Prince Armor?" Pound asked. "Flurry told me that if he ever found out we were dating, he'd have me sent to the gelding clinic."

"You're not in trouble," she assured him. "Firstly, I know Shining better than anypony. I know he would never do that to you, or anypony. Secondly, I don't think he... or anypony else needs to know anything about this. Especially your parents."

"Well, we can certainly agree on that," he said.

"I just want the truth," she said, pulling an old spell book from her shelf.

"Flurry already told you everything," Pound said. "Everything we did. She didn't use any other spells or anything."

"That you know of," she said, flipping through the pages of the book.

Pound wanted to argue, but bit his tongue. It was clear that her opinion on the matter would be unmoved. For his part, he could not deny the nagging doubt in the back of his mind. Perhaps she had cast an age spell on him without him knowing. Perhaps while he was asleep. Not that he minded if she wanted him to go down on her as a colt. He liked going down on her. Hell, she could have turned him into a dog for all he cared if it meant they could finally go all the way. Though he would still appreciate it if she had asked him first. Which she would have, if she had done anything like that. She would have asked, right?

"Okay. Here we are," Twilight said, arriving at the page. "This is going to take some time, and all of my concentration. But we should have you back to your old... your older self before breakfast."

~

Pound Cake rolled his shoulder. All the aches of his growth spurts through puberty were uncomfortable enough the first time around. "Well... that sucked."

Princess Twilight sat in her old office chair and sighed. The smell of o-zone and singed hair filled the room. "How in the world did she do that without you knowing!?"

Pound shrugged. "I have no idea. But are we done here?"

She nodded. "Yes, yes. You can go," she said, waving him off to leave. "To your own dorm room."

Pound grit his jaw. He and Flurry were both adults. They could do whatever they wanted. But while they were attending the school, they had to abide by school policy. And that meant no funny business.

Of course, they would only get in trouble if they got caught...

"But I didn't even do anything!" Flurry screamed.

"She didn't!" Pound Cake said, with the voice of a young colt. That being what he had become. Again.

"Obviously something happened!" Twilight said, pointing at Pound. "We need to figure out what keeps causing this! What spell did you use?"

"Nothing!" Flurry said. "I was extra careful to not use any magic at all! Not even to..." she blushed and made a jerking motion with her hoof.

"It's true! We were extra careful!" Pound said. "She didn't even use her wings or hooves to... you know, milk the age out of me."

Twilight rubbed her temples. "I realize I'm going to regret this before I even say it, but you need to tell me exactly what happened last night." The other two ponies blushed. "Yeah, I get it. You were fooling around. Can we please try to be mature about this?"

"Remember, no magic this time," Pound Cake reminded Flurry after they snuck into her dorm room.

"Yeah, I know," Flurry said, snugging the inhibitor ring onto her horn. "There. Now I can't even do it by accident." She grinned, and touched her hoof to his sheath. "Besides, I don't mind getting hooves-on."

"But what if Princess Twilight was right?"

"I'm not using my magic!"

"No, I mean about you... you know, milking the age out of me?" he asked nervously.

Flurry rolled her eyes. "Come on. That's impossible! The only thing that can do that is advanced magic, and I must have accidently done that when I..." She blushed. "When you made me cum so hard last time. You almost made me forget my own name! So that must have been when it happened. But this time..." Her hoof tapped against the ring on her horn.

"Still... maybe I should just take care of myself this time," Pound said nervously.

"So, what, we're just gonna watch each other have another clop session together?" she asked.

"Oh, no," Pound said with a grin. "There's no way I'd leave you unsatisfied, my princess." He laid down on her bed. "Your throne is ready, my lady."

Flurry Heart smiled and climbed into the bed, straddling his face with her hips. He cupped her vulva with his mouth and happily started licking away while his free hoof jerked himself off behind her. She looked down at his eyes and smiled as she ran her hoof through his mane. "Such a good throne..."

With a face full of Flurry's pussy, the young stallion didn't stand a chance. Before long, his shaft started to throb and pulse, sending several ropes of his sticky cum arcing through the air against the fur of her back. Rather than feeling disappointed, Flurry purred from his complement to how sexy he found her. "You're not done yet, are you?"

"Mhm-mhm!" Pound's objection was muffled into her pussy. He tried to shake his head, but it was firmly clamped between her thighs.

"That's what I like to hear," she said before she gasped. He had been a quick learner, and he knew exactly what to do down there with his tongue. She gripped his mane with both hooves and moaned. "Oh... oh fuck! Oh, it's gonna be a big one! I hope you're thirsty, because I don't want to have to change my sheets again. F-fuck! I'm gonna... I'm cumming!"

"... And she squirted so much that I damn-near drowned!" Pound said. "But I didn't spill a single drop!"

Twilight grimaced while listening to their graphic re-telling of the night. "Ugh... and then?"

Flurry shrugged. "He cleaned my back with a towel and then we went to sleep."

Is it possible that you could have cast a spell in your sleep?" Twilight asked.

Flurry shook her head. "No way. The ring stayed on my horn all night."

"And there was nothing else?" Twilight asked, looking back and forth between them. "No potions or enchanted toys or anything?" They both shook their heads. She leaned back in her chair. "Listen, I know that you two were trying to be careful, but this still happened anyway. And until we can figure out what caused it, you two need to stop... getting busy."

Flurry huffed. "But-"

"No buts!" Twilight said firmly. "I'm going to fix this, again, quietly. But if this happens again, I will be telling your parents. And as for you-"

Pound put his small, colt hoof up. "Yeah, yeah. I know. You don't get to date a princess without understanding the value of discretion."

Twilight nodded. "Right. Now let's get you fixed up. For the last time... Flurry, go back to your room." Flurry huffed in objection again, but left without another word.

~

Pound Cake groaned from the aches in his growing bones again as Twilight carefully adjusted his body's age again.

"I hope you both realize how reckless that was," Twilight said. "There is some kind of magic at work here that none of us understand and it's dangerous!"

"Like you were never a horny teenage." Pound grumbled.

Twilight rolled her eyes. "That is entirely not the point. Without precise control, this kind of magic could have killed you!"

Pound shrugged. "And?"

"Do you just not care?"

"I wasn't mincing words when I said she almost drowned me," he said. "She has really strong legs and with her weight on top of me like that..." He trailed off. "And as I started to black out, you know what my thought was? It wasn't fear of dying. I mean, yeah, maybe a little..." He grinned. "But mostly, I was thinking, wow, what a way to go!"

"Right. Anything to get your dick wet," Twilight snarked.

"Not really." Pound Cake frowned. "I know a lot of stallions only think with their dick. Especially when it comes to a pretty mare like Flurry. A princess no less. I mean, who wouldn't want to rut that!? But she said she's saving her virginity for the right stallion. And I..." His face turned red in a mixture of embarrassment and shame. "I actually just like going down on her more than anything. Pleasing her. The magic jobs she gave me were fine. And I know she wanted to do more... with her mouth. But... I don't know. It just seemed so wrong to me." He looked down at his sheath. "To put that in her mouth."

Twilight looked at his eyes and saw no dishonesty there. "I can tell you are one of the good ones," she said. "I'll give you that." His cutie mark reappeared as Twilight finished another round of aging magic. "Stand over by the height chart on the wall," she instructed. He did as he was told. He was back to his original physical age.

He leaned and stretched his limbs, getting used to the feeling of his age again. "Still, once she learns how to control it, it'll be a neat trick for when I get older. It's like the magical equivalent of the fountain of youth."

Twilight froze mid-step as the cold realization washed over her. "Uh... right. Just, um, have a seat. There's one last thing I need to do before you go." She flipped through another book to the page for memory spells.
