Cheating the Cycle of Life- A Padded Pony Collab

Twilight Sparkle, Princess of Friendship, squirmed. Her bowels begged for release, but she wouldn't let me, not into her new training panties. She looked at her foalsitter, Cadence, who had styled her mane into the ponytail she wore when Twilight was a filly. "Cadence, I gotta go potty." The mare said, letting loose a low, drawn out fart.

Cadence smiled slightly, looking at the mare she was foal sitting. She hadn't been surprised Twilight was an Adult Foal, she had been infamously hard to potty train. "I'm sorry sweetie, but your potty's still being cleaned." She giggled, "You made quite the stinky in it last time. Just go in your Pull-Up, and I'll change you."

be"B-but Cadence." Twilight whined, "I'm a big filly." She pouted cutely, when she felt the start of her manure slowly start to creep out. She squeezed, trying to hold it in. She lasted for ten minufore she felt more manure start to press out of her plot. She eeped in surprise. She sighed, "Fine." The big foal squatted on the floor, lifting her padded rump into the air. Cadence watched, smiling slightly. Twilight grunted, as her tail raised. A crackling and crinkiling sound could be heard, as a lump began to form in the back of the training panties. They discolored slightly, and began to sag from the load Twilight was filling them with. She grunted, forcing out more. Two minutes later, she sighed in relief., sat down, and squished the mess.

"Now, do you feel better after pottying into your training panties instead of holding in?" Cadence asked. She pressed a hoof to the back of the diaper, "You really had to go, didn't you Twily." She teased.

Twilight stuck her tongue out at her sister in law, blushing. "Y-yes, but I still wanna use the potty." She said, standing up. The mess had smashed against her rump. A foul stench wafted through Twilight's bedroom/nursery.

Cadence rolled her eyes, playfully swatting Twilight's messy rump. "Whatever you say Twily, you know you love diapees." She teased. Twilight smiled slightly. She waddled even more than usual as she was led to the nearby changing table for a change into a nice, comfy diaper.
