Marinette needs changing

As Marinette was halfway down with the other breast, she stopped. She bent her knees up and grunted a little. Alya knew what was happening, but she patted Marinette's padded bottom anyway. She felt her bottom get bigger, a sudden hotspot growing at the lump. She grunted a few more times before her legs dropped back down and she continued feeding. Alya rolled her eyes a little as Marinette made no sign of noticing her own bowel movement, too engrossed in her milk to care

Soon her breast was empty and she was able to pry the little off of her.

"I guess you were overdue, stinky-butt. Let's get you out of this thing."

"Sowy Alya," said Marinette as Alya got up, laying her back on the padded bench.

"It's okay baby girl. I know you can't help it."

She grabbed the various essentials from the nearby cabinet and dragged the diaper genie a little closer. She untaped her and opened the diaper up. While Alya was biologically predisposed for looking after a baby's needs, messy diapers were still messy diapers and Alya winced a little. As she began wiping her down, Marinette was distracted by the ceiling, various stars and moons painted on the ceiling as she reached up to them like a mobile over a crib.

Before she knew it, she felt a new, unsoiled diaper wrap around her waist and Alya took her hand before she helped her out of her sitting position.
