Sunny gasped again, biting her lip as the vibrator held in place by her wet diaper pulsed again, shut off, then pulsed three more times as she was stocking the shelves of the changing table with diapers fresh out of the packs, leaving just a little space on top so they'd have room to expand and fluff up a bit.

She was pretty certain she was learning how to tell who had the remote as Zipp and Izzy undoubtedly passed it to one another as they periodically kept an eye on her from the other room. Izzy was much more random with her presses; Sunny usually felt quite a few pulses of varying intensity before it stopped. Zipp was much more of a tease, usually giving her just a single short pulse every few minutes, and the pegasus usually had an eye on what she was doing before she starting pushing buttons.

It honestly made Sunny want to just say 'buck it', smash her diaper onto the floor and start grinding away to get some relief, and she was honestly curious about what kind of trouble that would get her in with her two caretakers for the day.

When she felt the egg inside vibrate again, she stopped what she was doing and sat down on the floor, moving back and forth, hearing her diaper squish and crinkle as she pushed into the carpet.

"Ah-ah-ah, is little Sunny being naughty little filly?" she heard Zipp's voice behind her.

Sunny's ears drooped; she thought Zipp had had the remote the last time, and had passed it to Izzy, who never looked before she pressed a button. They had been incredibly good at mixing it up and keeping her guessing.

"Sunny, are you misbehaving in here instead of finishing stocking those shelves?" she heard Izzy ask, coming into the doorway next to Zipp.

"Sorry, Sunny, you're not ending this test of yours that early or easily. Think you need to be taught to not be a bad girl," Zipp chastised, coming up and giving her diaper a few test pokes with her hoof. "And it's a perfect time to get you changed too.

With that Izzy entered the room and lifted her up with her magic, levitating her towards the new changing table.

"At least you got it stocked enough to be the first one changed on it!" Izzy told her as she laid her marefriend down as Zipp took her position in between her legs at the end of the table. Zipp reached up and pulled the tapes off one by one, then pulled the front of the diaper open, revealing the modestly wet interior, along with Sunny's more-than-modestly wet marehood.

"Izzy, could you go get the paddle for me? My little sis here needs to be punished," Zipp said.

"You got it!" Izzy said, zipping out of the room and trotting upstairs as Zipp slowly removed the egg vibrator, wiped it down, then set it to the side before opening the container of wipes, and began cleaning Sunny's diaper area, going slower around her most aroused parts, watching the earth mare shudder in response. Once that was done, she pulled the wet diaper out from underneath her, rolled it up, tossed it away, and got a fresh one unfolded, fluffed up, and slid underneath her just as Izzy was coming back into the room.

"Aaand here you are, Miss Zipp," Izzy said, telekinetically passing the wooden paddle with several holes drilled into it.

"Thank you very much, Iz. Do me a favor? Hold her legs up for me," Zipp said as she stepped to the side of the table, presumably to give herself more swinging space, as Sunny gulped.

"Not like you didn't have this coming, naughty girl," Izzy chastised, as she took hold of Sunny's back legs and held them up, making sure she wasn't going to be in the way of Zipp's angle of swinging.

Zipp waited a moment, letting Sunny shudder in anticipation for a few moments, before coming down with the paddle. There was a resounding 'whap!' that reverberated off of the walls, and Sunny let out a gasp of pain, and Zipp immediately followed with more, getting into a steady rhythm. The blows weren't insanely hard, but they certainly weren't just 'for fun', either. More along the lines of 'yeah, we're friends playing with each other right now, but you still tried to pull a fast one on us, so you're going to get it'.

On the tenth blow, Zipp paused.

"Think ten is enough for her to get the message, Izzy?" Zipp asked the unicorn.

"Mm, maybe," Izzy replied, leaning down to inspect Sunny's diaper area as she continued holding her legs up. "Especially since she might have liked that."

Izzy gently ran the tip of her hoof up Sunny's folds, getting the evidence of her arousal as a shimmery coat on her hooficure.

"What a poor kinky little filly," Zipp said, motioning for Izzy to let go of her legs, while she took hold of them to finish the change. "Oh well, here's hoping you learned your lesson, and back in this goes..." the pegasus said, giving the egg vibrator a quick coating of lube before slowly pushing it back into Sunny's folds, making sure it would stay put for the few moments it would take her to get her nethers powdered and get the diaper taped up, before securing the battery pack to her inner thigh again.

"Now if you can behave yourself for the rest of the evening, there might be a little treat in store for you after dinner. Speaking of which, we should probably get started on that, right Izzy?" Zipp asked as she helped Sunny off of the table.

"Read my mind, Zipp!" Izzy said, turning to leave the room and head for the kitchen.

"And you, little missy, see if you can get this nursery ready to sleep in tonight," Zipp told her, seeing Sunny's face brighten at the possibility of finally being able to use her crib tonight. All she had to do was finish stocking the shelves of the changing table, and put the sheets on the crib mattresses. As she put the last of the unpacked diapers on the shelf, she felt the vibrator shoot off a few pulses, distracting her from her tingling flanks for a moment.

'Just have to make it to tonight...' she thought to herself.
