Yes

"I um I don't know," Thalia answers blushing.

"Oh well let's check you," percy said pantsing thalia revealing that her plain white diaper had been tinted yellow.

He patted the changing table and watched as Thalia climbed up. Once she was laying down he opened her diaper and took a wipe and cleaned her then turning to Artemis he asked her to use her power to shave her. Once shaved he whispers something to Artemis who smirks and hands something to Percy that Thalia couldn't quite see. Percy rubbed some cream onto her followed by some powder he then taped the diaper up and had her stand up percy before she could look at herself he put a blindfold over her eyes.

Percy then took her shirt and bra off then started to dress her. It felt like a T-shirt that strains to hold her breasts then he put something in her mouth and after a second she could tell it was a pacifier he put what felt like a pair of leggings on and then took the blindfold off right in front of a mirror.

Thalia was mortified; she was in a dark gray onesie that had the words "punk and proud" in bubble letters across her chest and then had little lightning bolts and storm clouds covering it. It hadn't been but tended yet to show off her black diaper that was covered in cartoon raindrops that would fade when she was wet. The pacifier in her mouth was shaped like a skull and crossbones; her leggings were black and white striped. She looked like an overgrown infant and it was such a turn-on.

She began to each for her diaper but was stopped by percy who told her to wait. Then Artemis erased the mirror and reveals herself

They were in the same outfit except Artemis was in dark blue with silver letters saying "daddy's little star," it was covered with stars and moons her diaper was the same colour but with arrows and bows, her pacifier was a crescent moon and her leggings were pure blue.

"Now you two we are going to play a little game," he said, patting their bottoms as the diapers started to vibrate, pleasing them both. Thalia would have moaned if her pacifier hadn't acted as a gag.

"As you can tell your diapers are going to act as a vibrator first to cum losses," percy explains.
