Sunny was kinda, sorta ready to admit it to herself. She was pretty sure she was jealous of Sprout.

Pipp had been absolutely accommodating in every way she could with her new playmate, and her big sister had been ever the observant foalsitter, and had made more than one run out of the room to get whatever they needed for a meal or activity. But the fact of the matter was that the pair of adult foals were confined to her bedroom, spacious as it was. It was nearly the same to the hotel room she was sharing with Izzy, but she honestly missed having the run of Sprout's house, and now she was more certain that when the lighthouse reconstruction was complete, she was going to make the whole thing available for ageplaying.

"Pipp, I've been thinking," Sunny started, as they both were munching on double chocolate chip cupcakes. "You may not have to ask Sprout to try out his nursery. I've been considering making a portion of my lighthouse an adult nursery. This has been so much fun, I think it's something I want to incorporate into my living space, and it's something I want to share with all of my friends."

"That sounds like a fantastic idea, Sunny!" Pipp replied. "I'll certainly help with design choices if you'd like my input."

"Not to mention amenities for foalsitters, am I right?" Zipp asked, coming in with a couple bottles of milk.

"Absolutely. Caretaker comfort and immersion is just as important," Sunny agreed as she accepted the bottle of warm milk along with Pipp. The cupcakes they had just had made the milk taste that much sweeter, as their mouths were now eager for some liquid. "It's not like we don't have time, they won't be finished with the repairs for several more weeks."

Izzy walked up the stairs that curved up the outer edge of her home up to the second floor, carrying a bottle of chocolate milk, and trotted over to the balcony, where the door was open letting the cool night breeze in. The unicorn stepped through the door and saw Sprout sprawled out on his back, looking up at the night sky through the clearing in the canopy above.

"There's my little super soaker," Izzy commented, coming up and setting the bottle down next to his right front hoof.

Sprout blushed. He had been wearing diapers more often than not since this treatment had begun, and already he found himself wetting easier, releasing less more often instead of soaking it all at once every few hours. Yet, when he wasn't wearing, it was like nothing had changed. What he told Sunny was holding true; it wasn't undoing anything, rather it was another layer of training for his brain of acceptable places to go.

The red stallion glanced over at the bottle, wondering if he was in for another few hours of feeling small and foalish babble coming from his mouth. Izzy picked up his expression immediately.

"Don't worry, just straight milk this time, no magic tea," she reassured him. "Hope you didn't mind, I was wondering how you would like the experience," she said, taking a seat next to him.

"I didn't mind. It was... Interesting to say the least. Wouldn't mind doing it again, either," Sprout told her as he grabbed the bottle turned it over, and began to suckle at the rubber nipple. After a couple swallows, he pulled it from his lips. "I don't think I've ever seen this many stars in the sky before."

Izzy looked up, and recalled that their camping spot on the way here had been rather cloudy.

"Well, when you feel you've had enough foal time, we could camp outside the forest, and you can see a real starry night, if you'd like."

"I'd like that. Also wouldn't mind seeing more of Bridlewood. There's gotta be more in town than the Crystal Tea Room. That playground looked pretty fun, let's do that too!"

Izzy smiled down at him. She decided against telling him that Hitch would be taking over for her when they returned to Maretime Bay, figuring it would be a nice surprise for the stallion. Surprises were the best.

"Well, when you're finished stargazing, I've got your 'crib' ready for you," Izzy told him, then headed back inside while Sprout continued to slowly drink his dessert. The crickets started to get louder, and once he got the last few drops of milk out of the bottle, he rolled onto his stomach and got to his hooves. Trotting around the outer edge of the second floor, he descended the stairs and saw what Izzy had done to the couch.

It still looked like a couch, mostly, but she had added bars to the front, sides, and even to the back, making sure they all came to the same height.

"Whoa, you did this all tonight?" Sprout asked, astounded at his sleeping arrangements for the next few days.

"You get really fast at unicycling when you've been doing it as long as I have," Izzy commented. Sprout stepped up to have a closer look. It had considerably more flair than his crib at home did. Each bar had a different pattern of paint or engraving on it, like each one had come out of an arts and crafts fair, rather than the perfectly sanded and polished bars on his one at home. They didn't rise up quite as high as his did, but this was honestly much more than he was expecting on such short notice.

"It's great, Izzy. Thanks so much," Sprout said with a smile.

"Anytime! Now that you're standing, I don't even have to check to see if you need a change with how much you're sagging back there, so onto the mat, mister!"

Sprout felt himself get magically lifted up, turned over, and laid on his back, as Izzy performed what had become a routine changing by now. After that, he was picked up again and floated over the bars, where he was softly deposited onto the cushions of the couch-turned-crib.

"Sweet dreams, little Sprout. Tomorrow we can start getting things ready for our camping trip."

With that, Izzy shut off the lights and headed upstairs to her room, where she picked up her phone off of her nightstand, and opened the text she had gotten from Hitch earlier.

Izzy
Sounds great, Hitch. Sorry I couldn't get back to you earlier, was quite the busy evening getting little Spout set up for the next few days. I'll keep it a surprise and won't tell him you'll be taking over. By the way, if you're interested, I've got quite the magical tea that you can use on him.

Author's Note

Just double-checked my stats spreadsheet, and this has become my longest ageplay fic by far.

And I finally have a good idea of where I want to take it, and likely end it.

Don't worry, we've got a bit to go. As always, thanks for reading!
