Sprout's Second Chance

Sunny slowly came to, drool on her pillow, and her blurry alarm clock cleared to reveal that Izzy had let her sleep in quite a bit, as it was a quarter past nine.

"Alright, little missy, I think you've slept in long enough. Up and at'em!" She heard Izzy's voice, moments before her blanket was magically lifted away, revealing her wet diaper from overnight.

"Is my little filly wet?" Izzy asked as she pulled Sunny down to the end of the bed by her hind legs.

"Hey Izzy," Zipp said, coming up the stairs with a change of diapers. "I can do this change, your water is boiling downstairs."

Sunny blushed as Izzy stepped away and went down to the kitchen while Zipp took her place at the end of the bed between Sunny's legs.

"So, all ready to head back to making smoothies tomorrow, Sunny?" The pegasus asked as she untaped the earth mare's soggy diaper.

"It'll be nice to get back to my smoothie cart," Sunny admitted as she felt the wet diaper get pulled out from under her. "As long as we can finish up the nursery by tonight. It's been a nice week off, that's for sure. But it'll be nice to get back to, well, normal. The last thing I want is for something like this to get dull."

"Mmm," Zipp commented as she got Sunny's nether regions wiped down and the fresh diaper unfolded slid underneath, and around her tail. "Well, I guess I'll just have to make sure today is anything but dull then, won't I?"

Sunny raised an eyebrow curiously as Zipp sprinkled powder over her diaper area, but then instead of taping the clean diaper up, she trotted over to her bed area, and came back a moment later. Sunny heard the cap of a bottle get popped open, with Zipp softly humming to herself. The earth mare laid there, wondering what she was up to, and gasped sharply when she felt something cool and slippery slide into her marehood.

"Zipp, what is th... Oh..." Sunny was about to ask, but the words left her brain when she realized that the pegasus was putting a lubed up egg vibrator inside her, before strapping the small battery pack to her back right thigh.

"You don't mind if your big sis makes your day a bit more interesting as we give your endurance a little test, do you?" Zipp said, smirking as she brought the diaper up between her legs, smoothed it against her stomach, and taped it securely up, making sure the egg vibrator wouldn't be slipping out.

"There we go. Now I'm sure little Sunny wants to finish the nursery so she can finally spend a night in there, but first we need breakfast, don't we?" Zipp asked.

Sunny nodded sheepishly as she rolled onto her stomach and hopped off the bed, feeling the lube on the vibrator begin to warm up and get closer to her body heat. She walked down the stairs, diaper crinkling with every step, with Zipp right behind her, and stepped into the kitchen, where Izzy was finishing up their fruit-filled oatmeal, ladling it into bowls before bringing them to the table.

Sunny stepped up to the table, and Zipp waited right until Izzy made eye contact with her before hitting the remote control tucked under her wing, causing the egg vibrator in Sunny to pulse for just a half-second, causing Sunny's gait to stagger, and for her to gasp softly.

"Zipp," Izzy chastised. "Did you break out the toys already? Talk about beating me to the fun..." The unicorn whined.

"Oh, no worries, Izzy," Zipp reassured her, switching the remote off for now. "I have a feeling there's quite a bit more fun to be had today..."
