Yes

Timmy opened his mouth with confidence before closing it again, suddenly embarrassed.

Lila got on one knee and undid the buttons on his plastic pants. He was in-fact just wearing a regular diaper. One that he had peed in. Apparently he came ready to swim and had forgotten to get changed into a swim-diaper first. Oops.

"Come on. Lets get you in a swimmie."

Timmy replaced Jim at the changing table and he lied back on it as Jim went over to the box to fetch his friend a swim diaper for him to use. Meanwhile, back at the changing table, his mom had already undid the tables of his friend's diaper and began wiping at his loins, hairless as the day he was born thanks to the special soaps and lotions that the custom infantilism shop downtown sold. Timmy just relaxed with his hands behind his head as Lila lifted him by the back of his knees to wipe his butt and move his used diaper out of the way as Jim unfolded the new swim-diaper and slid it under Timmy for his mom.

Jim and Timmy have gone in their diapers and had their diapers changed in-front of each other since they were toddlers, and when you lived in a town where not only was it acceptable - if not expected of them - to wear diapers and use them and get changed out of them, you wouldn't find it embarrassing.

It was like seeing a relative or a close friend naked at a nudist camp: you kind of stop noticing and thus lack any shame in it.

Lila powdered him and taped him and he even rebuttoned his plastic-pants for him before helping him back up.

"Now that that's out of the way, who's ready to go swimming?"

Jim and Timmy exchanged looks before bolting out of the room, looking for stuff they wanted to bring with them.
