Starlight moaned quietly as she once again shoved her diapered crotch into the bear that had been wedged beneath her and the mattress of her crib, which had been teleported back to her bedroom after she had adamantly refused to be changed in front of Trixie's class. She figured that once the counselor had her class wrapped up, she'd be back to get her cleaned up, so why not have a little fun in the meantime?

That loss of control on stage had been surreal; she was going to have to ask Trixie to keep that spell handy in the future.

Her ears perked up at the sound of her bedroom door's doorknob turning, and it opened to reveal Sunburst.

"Well, there's my girl. Smells like you could certainly use a change. I trust you were well behaved for Trixie's class?" The vice headstallion asked. Starlight nodded as she was grasped by Sunburst's magic and carried over to the bathroom. He expertly began to untape her diaper and remove it as she was set gently down in the tub. He set the water to a lukewarm temperature, grabbed the detachable shower head, and immediately set to spraying her nethers down, keeping her tail elevated and making sure nothing got stuck or smeared on her back legs on the way down.

After about thirty seconds, she was decidedly clean back there, and was levitated out of the tub, being given a brief magical blow-dry before her tail was released from Sunburst's magical grip as she was taken back to the bedroom and set down on the changing table.

As Sunburst grabbed a clean diaper, unfolding it and fluffing it before laying it under her, he noticed how she hadn't quite finished from her plushie humping when he had come into the room.

"Well, I suppose I could take this opportunity to give the birthday girl my present." Sunburst told her.

Starlight barely saw him lick his lips before her stomach blocked her view of his head which had descended between her legs. Sure enough, she felt his tongue a moment later, and she let out a gasp. Gods, the mix of ageplay and adult naughtiness was like nothing else.

The vice headstallion didn't exactly have his work cut out for him; she was already quite worked up from her efforts before he had entered the room. He was always satisfied with how he could make her squirm, be it in their bed, in her crib, or even on the changing table. Sure enough, two minutes later, he was rewarded with a short pacifier-muffled scream and few squirts of her juices before he pulled back, sprinkled foal powder over where he tongue and teeth had just been, then brought the diaper up and taped it securely on both sides.

"What a good girl. Now I'm sure my little one is hungry for some lunch. Let's go get some."

"Hey Sandbar, you alright?"

Gallus' voice brought Sandbar out of the momentary mental distraction the stallion had found himself in standing in front of the sink of the colt's restroom outside of the auditorium.

"Huh? Oh, yeah. Sorry, got lost in my head there for a minute." Sandbar answered his boyfriend as he finished washing his hooves, then shut the faucet off.

"Are you sure? I think your cock could be seen from anywhere in the auditorium, and I haven't seen you this flustered since our demonstration with Ocellus in the tree house."

Sandbar had to mentally fight against another erection as memories from week two of Kinks and Fetishes flashed in his mind. Gallus and him had been going out for a few months now, and their dorm room activities had been the frequent source of curiosity of their four closest classmates. One night, they put on a little show for them, and before they knew it, Ocellus had joined in on the fun, which had disastrously ended in a burst of changeling magic engulfing the entire dorm and parts of the castle, giving everycreature within sudden and unexpected 'climaxes' in whatever dreams they might have been having. After a stern talking to from the then-guidance-counselor Starlight, they endeavored to be much more careful on where they had fun with each other.

Ocellus, Gallus, and Sandbar had been the first volunteers for the first demonstration of the class; interspecies relationships, polyamoury, threesomes, and how changeling magic worked with all of those, thus it had taken place in the magical crystal tree house in the remains of the Castle of the Two Sisters.

Their class was normally nearly twice the size, at eleven students, but Trixie had always been very clear on who and what the next class' demonstration would involve, and apparently, five of them weren't quite as curious when she had said the next demonstration would involve the school's headmare.

"Yeah, I'm fine. I guess that wasn't quite what I was expecting..." Sandbar replied.

"Well, you know, if you're that curious, I wouldn't mind if you wanted to try some ageplay. That's what this class is all about, right?" Gallus offered.

"Whoa whoa, I'm not saying I'm ready to dive on in or anything. But honestly, yeah, I might think about it. Besides, I'm not sure where I would even put stuff like that. So, to change the subject, we still on for lunch?"

When they had finally returned to their dorms, all six of them were plumb tuckered out after a day of Ponyville summer fun. Trixie's class rarely went past noon, and after that, the rest of the day was free to spend however they pleased, save for Ocellus, who had chosen two additional electives to take over the summer break. After a late dinner, they finally retired back to their rooms. When Sandbar discovered he was in the mood, he glanced over at Gallus and unfortunately saw that he had been out for a good fifteen minutes already.

So when he quietly went to the bathroom and took a seat on the tub, he realized that his usual train of dirty thoughts of Gallus and Ocellus weren't quite cutting it tonight as he tugged on his throbbing stallionhood as quietly as he could. After ten minutes of essentially edging himself, he began to get concerned that he was going to have to endure a night of sexual frustration until Gallus was awake and available in the morning.

But then thoughts of today's demonstration in the auditorium began to creep into his imagination. Within seconds, it wasn't Starlight in that crib, but himself. Soon enough, Gallus' disembodied voice was in his ear.

"Aw, is my little colt wet? Come on, let's get you changed."

Then, a flash of him being led into a bedroom, his bedroom, by the griffon, who then morphed into his dad.

"Son, at this rate, I think Coral will be trained before you. Come on, up you go."

The final barrier that he had been pressing against for ten minutes finally broke, and with a gasp, his throbbing erection erupted, spraying ropes of seed on the tiled wall of the tub. One... Three... Five.

He caught his breath as quietly as he could as the streams turned to drops, and he turned on the shower for just a moment to rinse off the wall. Taking a last deep breath, he shakily got to his hooves and hobbled out of the bathroom, turning off the light behind him and made his way to his bed across from the sleeping griffon. His newfound foalish fantasies began to fade in the afterglow, but he wasn't so naive to believe they wouldn't be back, and as he fell asleep, he began to wonder what he was going to do about them...

Author's Note

Sorry it took so long for another update.

No worries, it wasn't the pesky story rating, haters gonna hate and downvote and all that; I was just struggling with where I wanted to take this story, as I have shifted gears a bit to bring in other characters and try to link it to previously unrelated tales. Do with that what you will, and I hope you continue to enjoy.

Love,
Miles
