Once the ponies expressed their desires, Princess Celestia, slightly disappointed, spoke up.
"Well, it seems that you prefer occasional visits to your friends, instead of full-on support." Celestia winked. "Not that it's a bad thing. It's a way like any other."
Rainbow Dash hovered above ground.
"Can we go now?" she said.
"Of course yes! Let's go!" said Applejack as she ran towards the door... and was stopped by giggling Celestia. Applejack kicked the air around her as she was pinned.
"I thought we were free to go!" said Applejack with annoyance.
The white alicorn answered with a playful tone.
"I'd advise you get rid of your current attire before leaving."
Applejack slapped herself with her right hoof, while the other seven ponies, as if they feared a counter-order from Celestia about doing so, slowly untaped their diapers and discarded their accessories; the leaving mares got off their smocks and folded them.
Applebloom and Scootaloo left the pacifiers to Velvet, while Sweetie Belle decided to keep her pacifier and took two packs of diapers, saying that they could come in handy, if she and Rarity wished to try that again at home.
When all the ponies were finally ready to leave Velvet's house, Twilight's mother quickly handed a small black velvet sack to Rarity.
"There is the roll of film of your photos in there." she said with a big smile.
Rarity grinned awkwardly, thanked Velvet, hastily greeted Princess Celestia, Velvet, Twilight and Pinkie, and left the house with the other six ponies quickly following behind her.
When Twilight's friends left, Celestia went to the door.
"Well, that was pleasurable while it lasted, now I must adhere to my duties as a ruler."
She then flew off to the horizon,while Velvet waved to her. When she was done with the waving and came back in the house, Twilight sighed.
"Well, it seems that matter, anti-matter and strange matter have met here in my house. And I am matter..."
Some hours of forced naps, fought baths, some time in a dark corner, and a spartan and weirdly arranged dinner, it was, finally, time to go to bed.
Twilight hoped that, at least in this, Velvet was going to give some freedom of action.
Fat chance.
It was five past nine post meridian, when Velvet decided to grab Pinkie's and Twilight's tails, and bring them into Twilight's room, to much of the two ponies' chagrin.
While they were dragged up the stairs, Pinkie Pie and Twilight complained profusely.
"But I am not tiiiireeed..." said the pink pony with a whiny voice, one that seemed to mock one of an actual foal.
"Mother, once again. I don't need to go to sleep so early. I have to go to kindergarten at eight o'clock, not at six o'clock," said Velvet's daughter with a deadpan voice.
Velvet entered in Twilight's room, and closed the door. "You need those hours of sleep, Twily and Pinkie. After all, you don't want to be tired tomorrow, right?"
Twilight facehoofed.
"I don't want to, but..."
Velvet interrupted her daughter.
"Then you got to sleep now with our guest."
Twilight grunted, while Pinkie Pie continued her verbal fight.
"But I am still full of energy!"
An unfortunate, or maybe intentional, yawn followed.
"See? You are sleeping on all your fours." Velvet extracted the small bed that lied under Twilight's. "Come on, let's get ready for sleep."
While Pinkie Pie continued to argue, while pretending to be increasingly tired, Velvet's daughter sighed.
"Unavoidable embarrassing pajamas en route in ten, nine..."
As Twilight counted down, Velvet quickly unpacked the foldable bed and put sheets on it, then opened the drawer, extracted a lilac bag closed with sealing wax, destroyed the wax, opened the bag, and while she slowly revealed the content, she shouted: "Twily, put on your pajamas!" while levitating said article of night clothing out of its bag. Of course, said pajamas fit to the "theme," because it was white with a pattern of green kittens, blue hippos and pink elephants.
"Just as expected..." said Twilight, while rolling her eyes in annoyance. However, tired of the fighting, she decided to just get over with it as soon as possible, so she put her front hooves in the sleeves of the shirt and tried to fit her padded bottom in the pants. Alas, the trousers were too small to fit the diaper in, so Twilight struggled for minutes and minutes, her rage intensifying at each attempt, before hearing the giggle of an old mare behind her.
Twilight recognized it as her mother's voice.
"Mother, would you kindly explain to me how I am supposed to wear this trousers, if I have a diaper on me?"
Velvet terminated her giggle to reach to her daughter's face, pinch one of her cheeks, and say.
"You are not supposed to wear diapers, while you sleep," Twilight sighed in relief.
"It might be illogical," whispered Twilight to herself, "since she put me in diapers during the day, and now she is putting me out of them during the night. But, hey, it's not like she remembers that I was a bedwetter until I was seven, since, in her timeline, this date was never reached..." Twilight stopped mid-thought, when she arrived at that point.
"Wait... the fact that she gave me a pajamas with trousers that won't fit if I wear a diaper doesn't mean she is putting me out of them for the night..."
Twilight facehoofed at her own stupidity.
"It means she is just changing the type!"
And, while those words were thought, Velvet had left the room, and returned with a pack of pull-ups.
"Come on Twily, let’s put this on you."
Twilight took one of the pull-ups with her magic, feeling too annoyed and humiliated to even feel annoyance, humiliation, or modesty; and, after pocketing her hind legs in the garment, she pulled it up to her waist.
Meanwhile, Pinkie Pie was quickly explaining to Velvet that, no, she had no nightwear with her, and that it wasn't so cold to warrant one. Still, Twilight's mother forced the wearing of the pajamas, and relative adsorbent garment-swapping.
Once the two ponies were ready, Velvet raised the covers of the two beds as a silent invitation to get under them. The two mares complied without questions.
Velvet smiled, as she tucked the covers on her daughter.
“Do you want me to read a bedtime story to you?”
Pinkie Pie was going ot raise her right hoof, before Twilight could answer for both with a grin.
“No thanks, mother.”
Velvet smiled, kissed Twilight’s forehead, turned off the light then exited from the room, and bid them goodnight.
